"The technician's (Tim and Chaun) that did the installing of my HVAC were courteous and professional. Tim made sure everything was working to his satisfaction before he left and told us he would check back in a day or so to make sure it was functioning properly. My wife and myself very pleased. I should also state two years ago we had a new HVAC installed by Swift and continually had problems with it. After many service calls with little luck correcting the issue, Swift installed a new unit. Five more stars to Swift for integrity!"

"Job was completed in one day. It was convenient. I woke up with no hot water. Called Hill's (it was on a Friday) around 10am and they had one of their plumbers call me right back so I could explain the problem. He gave me a time that he would be at my home. He called me when he was on the way. He arrived at the time he had said he would (3:30pm). He showed me the problem. Water heater was leaking. (It was 22 years old). It needed to be replaced. I didn't have time or a truck to go purchase one myself. He replaced it and we had hot water by 6pm."

Heating and Air Conditioning questions, answered by experts

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

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.

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.
