It’s every cigar enthusiast’s dream—a room at home where you can enjoy the pleasures of the hobby without worrying about residual aromas or smoking up the house. As you might expect, there are a lot of logistics to consider to make it happen, first and foremost being an HVAC setup that can handle the job. So we asked A.N. Roth’s General Manager Richard Roth for some pointers on planning the perfect cigar room for your layout…

What kinds of HVAC systems work best for a cigar room?

Assuming the cigar room is a place to smoke and not store cigars, the best option is a ventilation system that exhausts the smoke while in use and replaces it with outside air. Called a DOAS (dedicated outside air system), this unit is a great solution in terms of performance, but can be expensive and often a challenge to install. Because the outdoor air is seldom ideal for indoor comfort, the ventilation equipment is specially designed to handle the extremes of seasonal temperatures, which leads to a premium price tag.

A more cost-effective solution would be a combination of exhaust, fresh outside air, and filtration capable of handling smoke particulate. With this kind of system, you can expect the room to get a bit smokey while in use, but to recover with fresh air in time. The good news is, like with a DOAS, the room maintains negative pressure relative to the rest of the building so no smoke would leave the cigar room, keeping the house smoke- and odor-free.  There is a bit of added maintenance, however. The filters become loaded with smoke and tar, requiring frequent cleaning or replacement.

How much space is usually needed for a separate cigar room HVAC system?  

It really depends on the size of the room and expectations of performance. A DOAS is usually a self-contained outdoor unit that requires a run of ducting to and from the room. You can expect to use approximately a 10’x10′ area outside for the unit, which then connects to the necessary duct pathways inside the home.

A non-DOAS system also requires space for hardware, though not as much. An 8’x 8′ room plus pathways for exhaust and fresh air ducts will usually suffice. However, the system size is ultimately determined by the size of the cigar room.

When building a cigar room, at what point in the construction process should homeowner’s contact an HVAC professional?

Getting an HVAC professional to help with the plans should be the first thing you do, even before talking to an architect or designer. They can determine whether there’s enough space for HVAC hardware and where the ventilation pathways should be placed. Otherwise, you might design a room and layout you love, only to find out the equipment you need won’t fit or work within your parameters.

We’ve all been there. A power outage knocks out electricity in the home and with no air conditioning or heating, inside temperatures can become extreme. That’s why homeowners are increasingly turning to generators to ensure their systems can continue to run when the power grid fails. If you’re thinking of adding a generator to your setup, here are a few things to consider…

Finding the Right Generator for the Job

Not every generator can manage the amount of electricity your home will need during an outage. Specifically, portable generators like the ones you find at your local home improvement store likely will not provide enough power and can potentially lead to electrical damage during power peaks. We always recommend permanent, stand-by generators to ensure you can keep things running safely and effectively. But even stand-by generators should be sized appropriately for the items you want to keep running when the power goes out. So ask yourself: Do you want to simply keep the pipes from freezing, the sump pump running, and the fridge and freezer cold? If so, a small generator would probably do the trick. However, if you want no drop in quality of life, including full HVAC functionality, a larger whole-house unit is best. While these do come at a higher price tag and may require an additional gas line and a larger meter, the peace of mind is priceless. Although A. N. Roth does not install stand-by generators, we can recommend a qualified installer who can do a walkthrough of your home to perform a load calculation to properly size a unit that can handle your needs.

Location Is Everything

Placement of your generator requires careful thought. They can be relatively noisy when running, so placing them near a bedroom may not be ideal, especially if it ever needs to run for several days at a time. But more importantly, natural gas and propane generators release carbon monoxide exhaust which can be deadly if not managed properly. Generators should be installed so that the exhaust is vented away from doors and windows. It’s also a good idea to invest in a carbon monoxide detector as an added failsafe. Another thing to consider is that exhaust puts out heat that can negatively affect landscaping. A qualified installer will help you find the perfect spot in terms of safety and convenience.

Maintenance Is Key

Regular maintenance is required for all stand-by systems. Generators will need to be exercised weekly, which means turning them on and letting them run for about 15 minutes. As a result, even if you don’t experience a power outage, the generator’s oil and air filter will need to be changed annually. Regular maintenance also helps you get familiar with your unit so when you do have an outage, you know how everything works and how to check and maintain the oil level.

Leave Installation to the Professionals

Installing a whole-house, stand-by generator is not a task to be taken lightly. It involves accessing your high voltage electrical panel, running new gas lines, and possibly even upsizing your gas meter. While to some these may not sound like perilous tasks, working with electricity and gas is best left to professionals. Even the smallest leak or issue can mean big problems down the line.  However, when installed correctly, a stand-by generator can do wonders to quell the worry and inconvenience brought on by unexpected outages.

 If you have any questions about installing a generator at your home or business, please don’t hesitate to Contact Us today!

There’s no question our furry little friends do a lot to brighten up our lives. But for some of us—especially those with pets that shed excessively—it can be a struggle to keep the hair and dander (and allergies!) at bay. We asked A.N. Roth’s General Manager Richard Roth for some helpful HVAC tips for pet owners and here’s what he had to say…

Is there a specific schedule you recommend to pet owners for changing their HVAC filters?  

If you’re using a 1” pleated filter, we recommend checking the filter when once per month. To tell if the pleated filter is dirty, you can hold it up to the light and verify it is still opaque or that you can see light through it, which means it’s still got some life left in it. Just because the white media has turned grey doesn’t necessarily mean it’s ready to be replaced. Once you get a feel for how often you need to change your filter, you should set a reminder on your calendar. It’s also a good idea to write the current date on the filter when you replace it.  We also recommend at least a MERV 8 filter and no higher than a MERV 11 for 1″ filters.

Another thing to be aware of with shedding animals is keeping return air grilles clean. This is the side of the system that pulls air in so pet hair can collect on the grille surfaces and restrict flow. Regularly checking the grilles and cleaning out the collected hair can be just as critical as checking the filters when it comes to alleviating pet hair and dander.

Should I be doing anything different for cats vs. dogs? 

When it comes to dogs, if your pet has access to your outdoor unit, it may choose your air conditioner as a regular spot to lift its leg. Over time the acidity of pet urine can dissolve the aluminum fins and ruin the performance of the system. It’s always best to encourage them to do their business elsewhere.

Do you recommend a specific air filtration system for pet owners?  

If protecting your HVAC equipment is your primary goal, a MERV 8 pleated filter will do the job, but we recommend using a MERV 11 if available. You can find a quality, reasonably priced MERV 11 filter at A.N. Roth’s online filter store. If you’re trying to catch particulate-sized pet dander, you’ll need to consider a polarized media filter or a HEPA style like the IQ Air Perfect 16.  More information about both of these can be found in the Healthy Home section of our website.

Is there anything an HVAC system can do to help with pet odor?  

Generally, odors should be handled at the source (that means you, Fido!), but there is technology that can be added to your HVAC system to neutralize odors. We use products called the PureAirX FM2 and RM2, which are UVC systems that produce a small amount of ozone. When applied correctly, ozone will mix in the air moving through the duct system, neutralize odor, and dissipate before leaving the duct system. This is the same process Mother Nature uses to neutralize odors by using sun rays, oxygen, and water present in our environment. (Click here for a more in depth video on the topic.)

As we say goodbye to the winter’s cold and prepare for the upcoming change in weather, we thought we’d ask A.N. Roth’s General Manager Richard Roth for some pointers on heating and cooling your home without breaking the household budget.

What are some simple things homeowners can do to reduce heating and air conditioning needs throughout the year?

A couple of really simple things to do in the summer would be to close your blinds and use ceiling fans. In the winter, you want to do the opposite. You’d be surprised how much heat the sun can generate in the home, as well as how much a fan can help you feel more comfortable at high temperatures. But for those looking to better address high bills or comfort issues, I suggest an energy audit performed by a home performance professional. The audit typically includes an infiltrometer test, infrared thermography, and sometimes a duct blaster test. I find this is the best way to get actual results. We always refer clients to Building Performance Group here in town, who are very thorough and helpful.

For those who have a traditional HVAC system, are there most efficient ways to use it?

This can be a loaded question. Generally speaking, programming a gas furnace in the winter when you aren’t home can save money. But programming an air conditioner is another story because we are also dealing with moisture removal.  I generally tell customers with conventional furnaces and AC to program heating for savings and AC for comfort. By this I mean furnaces are almost always oversized to efficiently heat the house when it is 0 degrees outside. In other words, they usually have plenty of capacity to catch up.

AC units on the other hand are sized to keep the house around 72-75 degrees when it’s 91-93 degrees outside. That means they usually don’t have lots of extra capacity. So programming for comfort means if you like it colder when you sleep, allow the thermostat to drop the temperature for sleeping but do not set the temp high when you are gone because you may not be able to recover on hot days. The AC also works much harder and uses more watts of electricity when it’s trying to recover in extreme conditions. That could add to your monthly bill.

For those with heat-pumps, these systems usually have electric resistance supplemental heat which costs 2 to 4 times as much to operate. This is important to know because if you let the house get too cold and try to warm it up the thermostat will usually use the electric resistance heat to recover.

If radiant or geothermal are beyond your budget, are there other options in traditional systems that are more environmentally friendly?  

This is another tricky question to answer because low operating cost doesn’t always mean more environmentally friendly. Generally in the U.S., the push is for electrification so I usually encourage clients to electrify their house as practically as possible. The first step is to make your home as easy to heat and cool as possible. That’s why, as mentioned before, I always recommend a home performance test. A high efficiency heat pump is also something to consider. Since heat pumps run the entire cooling season and most of the heating season, investing in a higher end unit pays off.  In contrast, air conditioners run about 1/3 of the operating hours per year as a heat-pump and the lifespan is about 75%, so there are less operating hours to recoup investment dollars.

For environmentally-motivated clients, we push them towards inverter compressor systems. When these first came out they were only in very high-end units but now there are mid-tier product offerings so you are getting most of the same utility and comfort without the Ferrari price tag.

As you can see, while there are some basic things you can do to keep costs down in the height of winter and summer, it’s not always that simple. However, with a little help or an upgrade or two you can find the right balance of comfort and expense. If you have other questions about heating and cooling on a budget, please CONTACT US. We love to talk shop!

Renovating a historic home is a commonplace occurrence. What is not commonplace is considering the “thermal envelope” of the historic home BEFORE renovations occur.

What exactly is a “thermal envelope”?

A thermal envelope includes everything on a house that shields the interior from the exterior elements: exterior walls, doors, windows. All of these elements contribute to having either a tight thermal envelope (good) or a loose thermal envelope (bad). A tight thermal envelope has little heating or cooling loss; a loose thermal envelope includes drafts and discomfort.

That being said, it’s important to consider that older homes were built during times when central heating and air were rudimentary or, in many cases, non-existent. Present day, we demand certain amenities that might be difficult to achieve in an older home. The major amenity we desire is a perfectly controlled indoor climate, no matter what the weather conditions or temperature is outside.

It is necessary to determine how to attain this ideal level of interior comfort before you renovate.

Here are some important considerations before renovation:

Find the Breaches in your Thermal Envelope

This involves doing a blower door test to find the breaches from the attic to the basement. This test determines where the leaks exist so that the house can be shored up, tightening the thermal envelope. Fixes include installing energy efficient/weatherproof doors and windows, enhancing insulation and adding air sealing to your house.

A common breach involves the Stack Effect (read our blog about this here), which is a very real problem in many of these historic homes. Essentially, this is the way air moves in and out of a building. Warm air rises, going out of the top of the house in the winter. While the warm air is moving out the top, cold air is pulled in through the lower floors. The summer brings the opposite effect: cold air falls to the bottom floors while hot air is sucked in through the upper floors.

2. Ductwork

As we stated before, historic homes were built during a time when central heating and air was not the norm. As a result, the ductwork in these homes can be too small, old and even leaky. Assessing the viability of your ducts before renovating is crucial to the future comfort of your home. A new HVAC system cannot operate with a faulty delivery system. Your HVAC professional can determine if your current ductwork can be salvaged, modified or if it needs to be replaced.

3. Furnace/Air Conditioner Size

After addressing all breaches to the thermal envelope, the homeowner needs to determine if the HVAC system is an adequate size to comfortably regulate the temperature in the house. Is it too small? Too large? A professional will be able to determine the best size for your house and your needs.

By prioritizing your comfort in your new space with the help of a HVAC specialist, you can stave off future problems that are hard to remedy once construction is complete.

At A.N. Roth Heating and Cooling, the most common problem they see is that they are not asked to get involved with a renovation until AFTER there are comfort issues. General Manager Richard Roth advises that if you don’t address your air sealing and balances before your renovation, “no air conditioner can help you.”

It is difficult to achieve a perfect “new construction” feel in an older home with respect to comfort levels. But with attention to ventilation and temperature which involves improving insulation, making your home energy efficient and air sealing throughout the space, an ideal temperature can be achieved and you can thoroughly enjoy your newly renovated space.

There are few things more miserable than the AC going out on a hot summer day. So how did folks cope with hot weather at home before the advent of the air conditioner? The answer’s simple: houses were designed a bit differently to better fit the climate and, most importantly, beat the heat.

The Shotgun House

Shotgun houses got their name from their layout—you could hypothetically shoot a shotgun through the front door and it would go all the way through the house and out the back door. One of the biggest benefits of these oblong houses was that they maximized airflow by allowing cross-ventilation through the lined-up doors and windows. This would flush out the stagnant, hot air while encouraging the flow of new, cooler air to help maintain a reasonable temperature.

Wraparound Porches

Wraparound porches not only provided ample space to gather, but also served as a solace away from the indoor heat. People would sit outside on their porches, enjoying the shade and the summer breeze. These porches also cooled down the air directly outside of the home, helping to ensure that the air that trickled in through doors or windows would be colder than the air radiating off of a sunlit porch.


Designed to improve ventilation, cupolas are small structures with windows or vents that sit atop a roof. The vents are angled downward so that the fresh air from outside filters in to provide oxygen for the people and animals inside. As the fresh air enters, heat and moisture escape, keeping things comfortable while also keeping wood and hay dry.

The Dogtrot House

A dogtrot house features a less common design that’s often associated with the South. These houses are distinguished by an open-ended passage or breezeway between two living spaces. The purpose of the hallway is to optimize airflow between the two areas—one being a living space and the other a kitchen or dining room.


Awnings are used not only for aesthetic purposes but also for providing shade, as they prevent sun rays from entering the home. While some sun is appealing, too much can cause the house to warm up to unbearable temperatures in the summertime. As an added benefit, awnings serve as a source of shade on your porch or patio as well.

Transom Windows

Dating back to 14th century Europe, transom windows are set in a horizontal beam above a door frame. In modern day designs, they are mainly decorative, but their original use was to provide ventilation while the door beneath was closed. This was ideal because air could pass through the windows while maintaining the security of the home.

Enter Modern Air Conditioning

Since Willis Carrier invented the electric air conditioner in 1902, home designs have opened up a bit, while transoms, awnings and other features that help keep a space cool have become less popular. Of course, that means when the AC goes out nowadays, things can really heat up inside. That’s where A.N. Roth can help. Since 1866, when Jacob Roth began selling and installing coal and wood-burning stoves, Louisvillians have come to rely on A.N. Roth Company for heating and cooling solutions for their homes and businesses. So next time you’re having HVAC issues, don’t hesitate to CONTACT US so we can bring comfort back home!

Over the last year, many people have become aware of the need to consider the air quality in the home. As the United States moves towards reopening post-pandemic, more are becoming aware of the need to consider indoor air quality in public spaces, especially offices and schools.

Americans spend, on average, about 90% of their time inside. Between homes, offices, schools, and other public buildings, most of the air we breathe is indoor air. Additionally, studies indicate that indoor air is often significantly more polluted than outdoor air, even in the most industrialized cities. For this reason, indoor air pollution can have more of an impact on our health than outdoor air pollution. Indoor air quality is influenced by many factors, such as the type of building, age, humidity levels, filtration, ventilation, and more.

Sick building syndrome usually presents as headaches, nausea, respiratory irritation, dizziness, and fatigue.

Higher-risk populations are more likely to experience the effects of any pollutants, for example, children, the elderly, and immunocompromised individuals. However, anyone who experiences prolonged exposure to polluted air has the potential to experience health effects. These can range from relatively mild to life-threatening depending on the person, the type of pollutant, and the exposure. There is even a condition called sick building syndrome, or SBS. SBS refers to the symptoms of illness experienced in connection to a particular building.

What’s in the Air?

Air pollutants are minuscule, often invisible to the naked eye. The EPA identifies six common pollutants which are regulated and used as indicators of air quality. Particulate matter (or particle pollution) and Volatile Organic Compounds, or VOCs, are two of the most common categories of indoor air pollutants.

Particle Pollution

Particle pollution is a huge problem worldwide.

Particle pollution is classified into three categories based on size: coarse particulate matter, fine particulate matter, and ultrafine particles. These encompass a range of pollutants, many of which are common in offices. For example, the air in many offices contains biological pollutants like bacteria, dust, mold spores, pollen, and cockroaches particulates. Buildings near busy roads or industrial areas are also likely to have fine and ultrafine particles from vehicle exhaust, power plant emissions, and smoke.

Out of all of the most common air pollutants, particulate matter causes the most adverse health reactions worldwide. This kind of pollution is associated with a range of respiratory problems like bronchitis, asthma, and increased mortality from COVID-19. In addition to respiratory and pulmonary problems, particle pollution is also closely linked to cardiovascular disease.

Volatile Organic Compounds

VOCs are gases emitted primarily from human-made sources. Sources of VOCs include cleaning products, pesticides, building materials, new furnishings, carpets, paint, copy machines, and more. As you can imagine, VOCs are common in office buildings, and especially in new developments.

Exposure to VOCs causes ear, nose, and throat irritation in most people. VOC exposure can damage the liver, kidneys, and central nervous system and cause certain cancers.

Work-Related Problems

In addition to the acute symptoms of sick building syndrome, low indoor air quality causes many other issues that can impact employees. With the advent of COVID-19, a serious concern is potential infectious disease transmission. Poor ventilation has been linked to the transmission of other diseases like severe acute respiratory syndrome (SARS), hantavirus pulmonary syndrome, and Norovirus.

Among students, poor indoor air quality increases absenteeism and lowers test scores. Alternatively, among employees, higher indoor air quality results in better cognitive function, decision-making ability, and strategic thinking. In other words, it’s in everyone’s best interest, and a sound investment, to ensure that your office building has good air quality.

How Can We Fix This?

Air-Quality Assessment

This will allow you to determine the current air quality, pinpoint potential issues, and determine solutions.

An air-quality consultation will help identify pollution sources, whether they originate indoors or outdoors. It will also consider the age and condition of the HVAC system and inspect the air handlers and distribution systems. A professional will determine the health of your building and make recommendations in regard to ventilation, air filtration/purification, as well as temperature and humidity levels.

Air Filtration

The expense of clean office air is offset by saved human resource costs.

The most crucial solution for low indoor air quality is an HVAC system that effectively filters most airborne pollutants. We previously wrote about the capabilities of the IQAir Perfect 16, which is a high-performance filtration system available for homes and commercial developments. It removes not only 95% of particles larger than 0.3 microns, but it’s also 85% effective in removing particles above 0.003 microns (the smallest that exist.) And because it’s installed into the existing HVAC system, the IQAir Perfect 16 continuously delivers fresh, medical-grade clean air throughout the building.

Once you’ve upgraded your air filtration system, regular maintenance and changing the air filters are vital to keeping any filtration system in top condition. Installing an indoor air quality monitor will also keep track of pollutants and report fluctuations.

UV Purification

The IQAir Perfect 16 is not the only way to improve air quality in your home or office. There are personal air purifiers, humidifiers, dehumidifiers, and UV germicidal air purification systems. UV purification systems use ultraviolet light to render the environment inhospitable for a range of microorganisms.

April is a great month to think about energy use, and how we can be good stewards of our environment. There are many changes individuals can make to help reduce environmental impact. That includes our residential HVAC systems.

A huge amount of energy is expended on HVAC. In 2020, about 10% of all the energy used in the U.S. was devoted to cooling building interiors. On average, more than half of American annual household energy consumption is devoted to heating and air conditioning.

Inefficient HVAC contributes to greenhouse gas emissions.

HVAC is also responsible for a huge percentage of carbon emissions. Direct greenhouse gas emissions from homes and businesses – primarily combustion of natural gas and petroleum for heating and cooking – accounts for over 12% of total U.S. greenhouse gas emissions.

As demand for more environmentally friendly HVAC systems grows, the market is rising to meet it. Here are some of the environmentally friendly HVAC technologies that are available for residential homes:

Radiant Heat

We’ve written before about the benefits of radiant flooring. The concept of radiant heat is ancient, but new technology means radiant heat is clean and accessible for everyone. Radiant flooring doesn’t have to rely on fossil fuels. It’s more efficient than forced-air heating because it eliminates duct losses and uses less electricity than forced air systems.

Radiant flooring can be achieved with hot water tubes or electric wires under the floor. Heat then rises from the floor, warming the entire home evenly. It’s not only better for the environment, but it’s also healthier for you! Radiant heat doesn’t distribute allergens as forced-air systems do.

Geothermal HVAC Systems

Geothermal energy has been used to heat and air condition buildings for decades and has many benefits. The temperature below ground remains relatively consistent throughout the year, despite fluctuations in weather. Geothermal systems tap into this free energy via an “earth loop” of underground pipes.

During a heating cycle, a geothermal heat pump extracts heat from the ground. As the system pulls heat from the earth loop it distributes it through a conventional duct system as warm air. Alternatively, the same heat energy can also be used for a radiant floor system or domestic water heating.

Infographic illustrating how geothermal systems workIn the cooling mode, the heating process is reversed, creating cool, conditioned air throughout the home. Instead of extracting heat from the ground, heat is extracted from the air in your home and either moved back into the earth loop or used to preheat the water in your hot water tank.

Geothermal systems eliminate high oil, gas, propane, or electricity bills, and are the most energy-efficient, cost-effective, and reliable home comfort system available. Geothermal systems also eliminate outdoor unit noise.

Smart Home and Zoning

Smart HVAC systems are excellent for helping homeowners save energy and lower bills. Zoning allows you to control temperatures from distinct thermostats on different floors or areas. With a zoned system, you can even control the airflow to individual rooms. This is helpful if you need more heat to a certain area, or if you want to avoid wasting energy in a room you’re not using.

Smart home solutions offer features such as energy tracking, filter alerts, maintenance notifications, and automatic energy savings when you’re out of the house. They also offer homeowners the opportunity to set up alerts when an issue arises with your system! With WiFi-enabled units, your smartphone or computer keeps you in control of your HVAC system, whether you’re at home, at work, or away on vacation.

Realizing that your air conditioner isn’t working on a hot day is unpleasant, inconvenient, and expensive. Get ahead of potential HVAC problems by using the mild spring days to make sure everything is in tip-top shape. You’ll be thankful that your air conditioner is running smoothly when summer comes around. Here are our top spring HVAC tips.

Turn Your System Off

Enjoy some fresh air! One of the best things about transition seasons is getting the chance to improve air quality in your home by turning off your HVAC system and opening the windows. Enjoy the days that you don’t need heat or air conditioning and turn on the fans to improve air circulation.

Do Some Spring Cleaning

While your windows are open, roll up your sleeves and do some spring cleaning. Clear debris from your outdoor unit. Clean the vents and make sure they’re not blocked by carpets or furniture. Have your ducts cleaned. Change your air filters. Anything you can do to keep your HVAC system free of obstructions, small and large, will improve its efficiency and prolong its lifespan.

Check Your Ceiling Fans

We’ve said it before; transition seasons are the perfect time to take inventory of your HVAC system and all of its components. That includes your ceiling fans. During the winter, set your fan to turn clockwise and push warm air back down. During the summer, running your ceiling fan counterclockwise pulls warm air up and pushes cool air back down. Most ceiling fans have a switch that changes the direction, helping you save big on your energy bill.

Check Your House for Leaks

Paying to cool the air in your home, only to have warm air infiltrate your house through leaks, is a colossal waste of energy and money. Help keep your home more comfortable and lower your bills by sealing up drafty windows and doors and making sure your attic is properly insulated.

Get Regular Maintenance

There are a few things you can do regularly to help keep your system running smoothly, but the number one thing you can do is have regular preventative maintenance. Having your HVAC system inspected by a professional will help catch small problems before they become big problems. It’s the best way to ensure that your system doesn’t go out unexpectedly. Having your system serviced routinely also helps your system run more efficiently, saving money on your energy bills.
