Air Conditioner in the Basement – Is It Really A Good Idea?
You can choose to make your basement a sanctuary by installing an air conditioning system or make it a dungeon by blocking ventilation and impeding airflow.Schedule Free Inspection
You can spend a lot of time and money finishing the basement, but if you overlook the ventilation, your life may become miserable. The truth is that airflow affects the conditions down there and your home by extension. We wouldn’t advise you to downplay ventilation as your basement can become dusty, damp, and dangerous.
Since basement ventilation matters a lot, we shall look at why installing an HVAC system makes sense, what the HVAC code says, and what options you have before you make a move.
Why Ventilate the Basement?
Moisture is the number reason you should ventilate the basement, as nearly all homes in Washington, DC, are vulnerable to its effects. You may not notice there’s a problem until you do an inspection. Unfortunately, for some people, it might be too late to take any meaningful action.
Left unventilated, your basement can become a repository of mold spores, pungent smells and other harmful pollutants. The fact that it sits low also makes it susceptible to moisture and cold air that seeps in through wall and floor cracks. When this cold air comes into contact with the warmer air in the basement, condensation occurs. This creates the perfect conditions for mold and mildew to grow. Ventilation ensures the basement receives a constant supply of clean, fresh air that inhibits condensation and other secondary problems.
Your once stale basement will become more comfortable and habitable just like the living space above. Constant air movement ensures air doesn’t stagnate or get stale, which means fewer mold spores and bacteria growing on the basement walls.
What is the HVAC Code for Finished Basements?
If your basement doesn’t have windows, or the existing ones are not adequate for providing the right amount of ventilation, you may have to install a ventilation system for the safety and health of the occupants. You can only enjoy the living space in your finished basement by making it cool and comfortable. An HVAC specialist can help you size and install the right air conditioning unit so you can create the perfect indoor environment.
Your Basement Ventilation Options
We all like options, including how you’re going to ventilate your basement. Let’s look at the options on the table for you.
- Portable Ventilation
This is by far the most affordable and hassle-free method of ventilating your basement. You can get air moving throughout your windowless basement. All you need is an air purifier that pulls air into the unit and moves it out using a series of filters. The filter traps various microscopic particles such as dust, bacteria and mold spores before releasing fresh and particle-free air back to your basement.
Similarly, a dehumidification unit – like the JES dehumidifier – can improve the overall air quality throughout not only your basement but the rest of your home as well. Our powerful, yet energy-efficient units clean and filter the air, control moisture and humidity, and reduce odors and the potential for mold growth. These units can be ducted and are self-draining, so you don’t have to worry about emptying any buckets or reservoirs. These dehumidifiers can be directed to drain into your sump pump system or through a condensate pump.
- Mechanical Ventilation
This type uses fans to bring in fresh air and exhaust to push out polluted air. There are two ways of accomplishing it. The first is installing a fan inside the window so indoor air gets pushed outdoors. The other option is to set the air conditioner inside the window so indoor air gets pumped outside. Mechanical ventilation creates its own airflow, making it suitable throughout the year regardless of the season. On the downside, running these systems can increase your energy bill. And you must have a basement window and/or an exhaust fan.
Expand your central air conditioning system: If the indoor air in your basement is either too cold or hot, it makes sense to expand your HVAC system or add a separate unit. Extending your current HVAC system will help you regulate the basement conditions much better. However, this will only work if the existing unit can handle the extra square footage from your basement. Talk to your HVAC contractor to find out whether the AC system can adequately cool the additional space or whether a larger air conditioner will do the trick.
- Install a ductless mini-split system
If your air conditioner is fairly new but still can’t handle the extra load, get a ductless mini-split system. They’re not only capable of regulating temperatures, but they’re extremely energy-efficient and powerful. By installing them, you get maximum comfort and a chance to save your hard-earned money.
