Common signs of insufficient return air include uneven temperatures, with some parts of your home feeling hotter or colder than others, and noticeable differences in air pressure between rooms. You might also observe that more air is blowing in rooms closer to the AC unit. Leaky air ducts can also be a related issue or clue.

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.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.
