Top 6 Signs You Need AC Coil Cleaning in Greenville, SC

Top 6 Signs You Need AC Coil Cleaning in Greenville SC

An air conditioner works in a continuous cycle to keep your home cool. It has an evaporator coil that removes heat from circulating indoor air and a condenser coil that releases this heat outside. These coils must be maintained or your AC system will decline in performance and efficiency. Dirty coils are a leading cause of air conditioner problems. Here are six signs you may need an AC coil cleaning in Greenville, SC:

1. The System Runs for Longer Than Normal

An AC with dirty coils works harder to cool an interior space to the desired temperature. It will also run for a longer period. Air conditioning systems should turn on and off at predictable intervals. But if the coils are dirty, air may blow from the vents, and the blower may run longer or constantly. Longer running times increase wear and tear, which can lead to costly repairs and breakdowns.

2. Your Energy Bills Have Gone Up

Since dirty coils cause an AC to work harder and run longer, the system will use more electricity overall. Therefore, you’ll see a higher energy bill compared to the same time last year. It may also jump considerably from month to month. Utility companies generally don’t change their rates that quickly, so take this as a sign to check the coils. If they’re dusty and grimy, a coil cleaning should lower your monthly energy bill.

3. Warm Air Is Blowing From the Vents

Heat cannot transfer as effectively through a dirty coil. Therefore, your AC unit cannot cool your home as effectively. The air it produces may be less cool, or the unit may blow warm air no matter how cool you set the thermostat. If you have a central air conditioning system, some rooms may feel warmer than others, and it may take longer for the system to reach the right temperature.

4. The Coil Freezes Up

Ice on an evaporator coil often means that buildup is causing the refrigerant to run at a colder temperature. Any moisture that condenses on the coil can freeze. If the coil isn’t cleaned, your AC may lose the ability to transfer heat and cool the air in your home. Frost and ice can also damage the coil and cause the system to break down, requiring expensive repairs.

5. Indoor Humidity Is High

The evaporator coil both transfers heat and reduces humidity. During heat transfer, condensation forms from moisture in the air that blows over the coil. A buildup of dirt impedes this process. As a result, your home will feel more warm and sticky due to an increase in humidity.

6. Your Home Smells Musty

If a musty odor is coming from your air conditioner, dirty coils may be causing fungi, including mold, to grow. Mold and mildew will continue to grow until the problem is fixed. They can even spread throughout the AC unit and your HVAC system, while mold spores will circulate in your home continuously until the coil is properly cleaned. Bacteria, algae, and other microorganisms can thrive as well.

When Should I Clean My AC Coils?

An AC coil cleaning in Greenville, SC, should be done twice a year, once during professional heater maintenance in the fall and as part of AC maintenance in the spring. If you have older equipment or use your AC more frequently, clean the coils more often. Also, consider more regular coil cleanings if you live in an area with higher air pollution, whether due to street traffic, factory exhaust, or construction.

Can I Clean the Coils Myself?

If the coils are lightly coated, clean them with a brush and cleaning solution. But it’s generally recommended to hire a professional. They are trained to handle different AC units and their parts and thoroughly and carefully clean the evaporator and condenser coils without causing damage. Specialized tools and cleaners help them remove stubborn dust, dirt, and grime and check for other issues to address.
