One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

Here’s how AC professionals will clean your AC coils:

1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

2. Remove the faceplate.

3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

5. Use the vacuum hose to suck up any extra debris.

6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

7. Let the solution sit for at least 15 minutes.

8. Gently wipe away loosened grime and debris with a microfiber cloth.

9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.
