Proven Solutions to Counter Air Conditioning Unit Smells

Smelling HVACWhen you press the power on button on your AC, your expectation should be to feel the AC actually powering on and not emitting smells. Homeowners have been victims of stinky side effects of cooling systems and this affects the overall comfort in the home.

There are solutions that are proven to work to deal with conditioner’s smells. Learning the causes of these smells and understanding how the solutions work can liberate you.

Causes of AC Smells

Mold and mildew are the primary suspects causing air conditioning smells. Circulating air in your home causes airborne contaminants to settle within the system. This can happen even when the system is idle during winter.

When the contaminants in your system pair with the damp and cool conditions, mildew and mold forms which carry the smell into your home together with the circulating air.

The other cause of smelly ACs is dirty air filters. Your air filtration system pulls odor-causing contaminants from the air supply as it circulates. If you don’t change your air filter regularly, the captured contaminants may recirculate back into your home when the AC is in use.

Not all smells in your home originate from the AC unit. Some may be picked up elsewhere and then re-circulated throughout your HVAC system. Check out for substances such as exhaust fumes, chemical cleaners, perfumes and candles.

Fighting AC Odors

There are several ways you can deal with air conditioning odors. The following are easy to follow and implement.

Change Your Habits

Making simple changes to your day-to-day habits can help rid odors from your indoor space. For instance, when showering or cooking, use exhaust fans to blow away any smells. If you are using chemical cleaners remitting toxic fumes, you can switch to natural cleaners.

To remove contaminants from your home, vacuum your floors and clean surfaces regularly. Any linen should be washed frequently to discourage accumulation of dirt.

Change Your Filter Regularly

Your air filter should be changed at least once in 3 months. Such regular changes help in removing contaminants from your system thus preventing any recirculation of air back into your home. This minimizes the smell. If you can, switch to high efficiency filters that have higher MERV ratings.

System Cleaning

Components such as evaporator coils should be cleaned on an annual basis by a qualified HVAC professional. This works to reduce the smell and also enhance the efficiency of your AC unit. When dirt, mildew, and mold accumulate on your coil, they reduce air flow hence lowering the unit’s efficiency.

During the cleanup process, also check the ductwork, drip pans, and condensate drains. This helps in preventing the buildup of contaminants.

If resources permit, go for a whole home air purifier to help you pull pollution completely out of your home. This creates a cleaner and healthier indoor environment.
