Q: Why won't my AC cool after a power outage?

• <div><p>Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. </p></div>

Q: How do you remove mold from an air conditioner?

• <div><p>You may be able to <a href="https://www.angi.com/articles/how-rid-your-ac-mold-and-more.htm">clean mold from your air conditioner</a> in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. </p></div>

Q: What are the warning signs of not enough return air?

• <div><p>The first sign you're not getting enough return air is if some parts of your home feel hotter or colder than others. If nothing else is causing that, leaky air ducts are your next clue. If the air pressure feels different in every room, this is also usually a sign of insufficient return air.</p></div>

Q: How do professionals clean AC coils?

• <div><p>Here&rsquo;s how AC professionals will clean your AC coils:</p><ol><li><p>Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.</p></li><li><p>Remove the faceplate.</p></li><li><p>Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.</p></li><li><p>Use a soft-bristled fin comb to remove stubborn caked-on debris.</p></li><li><p>Use the vacuum hose to suck up any extra debris.</p></li><li><p>Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.</p></li><li><p>Let the solution sit for at least 15 minutes.</p></li><li><p>Gently wipe away loosened grime and debris with a microfiber cloth.</p></li><li><p>Reattach the faceplate, plug in your AC system, or turn the breaker back on.</p></li></ol><p></p></div>

Q: Can a frozen AC unit cause damage to the system?

• <div><p>If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.</p></div>

The first sign you're not getting enough return air is if some parts of your home feel hotter or colder than others. If nothing else is causing that, leaky air ducts are your next clue. If the air pressure feels different in every room, this is also usually a sign of insufficient return air.

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

Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.
Remove the faceplate.
Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.
Use a soft-bristled fin comb to remove stubborn caked-on debris.
Use the vacuum hose to suck up any extra debris.
Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.
Let the solution sit for at least 15 minutes.
Gently wipe away loosened grime and debris with a microfiber cloth.
Reattach the faceplate, plug in your AC system, or turn the breaker back on.

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.
