Why must I change my air conditioning filters?

The most important maintenance task that is also the easiest and most neglected is to routinely replace or clean its air filters. Our customers often wonder why their AC is not cooling well and many times it’s the result of clogged, dirty filters blocking normal airflow and reducing their system’s efficiency.

With your HVAC system’s normal airflow obstructed, air that passes by the filter may carry dirt directly into the coil and impair its heat-absorbing capacity. Replacing your dirty filters regularly with a clean one can lower your energy consumption by 5% to 15%. That’s the difference between a low or high electricity bill each month.

Replace your air filters regularly for optimal performance from your AC and less repairs in the future!

What's the importance of having regular maintenance from a professional for my air conditioner?

Regular maintenance from an HVAC professional keeps your air conditioner running as efficiently as possible in the blazing summer heat of Columbia, SC and surrounding areas. Maintaining your air conditioner unit will save you money in the long run by extending the unit’s overall lifespan.

What other maintenance can I do on my AC?

The coils in you air conditioning unit collect dirt over time. Changing your filters prevents the evaporator coil from soiling quickly, but in time dirt collects anyway. This dirt and debris reduces airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check your evaporator coil once a year and clean it as necessary.

You can also minimize dirt and debris near the condenser unit. Your dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris. Cleaning the area around the coil of your AC unit and removing any debris allows for adequate airflow around the condenser.

How can I make my AC more energy efficient?

The quickest and cheapest way to become more energy efficient is to regularly change your air filters. If you’re replacing a unit, switch to a high-efficiency air conditioning unit and you may save 20-50% on your electric bills.

Why should I change my duct system?

Efficient Duct Systems optimize the home’s comfort delivery system. To create a comfortable environment in your home, an efficient duct system is a must and if you live in an older home, your duct system is outdated. In a typical home about 20 percent of the air that moves through the air duct system is lost due to leaks, holes, and poorly connected ducts.
