"Great experience with seasonal maintenance check. They arrived early in appointment window, checked furnace, humidifier, & air conditioning, explained everything clearly. They replaced a filter, examined every part of air conditioning system, made some recommendations, had easy payment system. I will look forward to using them again!"

"Our residential AC is in a converted bus. We are new to the area, and first called several other companies who could not work on it (because they were RV repair technicians and not HVAC certified) or would not work on it (because most HVAC certified technicians were not work on motorhomes). We are so grateful that Pacific air was willing and able to work on our unit. We are fully satisfied with the work they did, as well as the very reasonable fee they charged."

"I recently had Comfair Heat and AC install a new furnace, and I couldn’t be happier with the experience. From start to finish, the team was timely, professional, and incredibly friendly. They showed up exactly when they said they would, walked me through the process, and completed the installation efficiently without cutting any corners. Their pricing was very fair compared to other quotes I received, and the quality of their work truly stands out. The new furnace runs perfectly, and the difference in comfort is noticeable already. Overall, Comfair delivered fantastic service, and I highly recommend them to anyone needing heating or AC work. I’ll definitely be using them again in the future."

"My central air system was failing to turn on at the beginning of summer. my first estimate stated that I had needed a new furnace @ cost 💲 6500+ . Luckily I was able to find Matt on Angi’s list. He was available the following morning . His recommendations were back to basics - cleaning of the furnace and AC unit , and a few simple repairs to both the AC and furnace - $850 later my AC unit is back to functioning normally! Matt was very knowledgeable , honest and provided excellent communication on what his findings were so I knew exactly what the game plan was. I really appreciate his straight forward, honest approach and would highly recommend him to anyone ! Thank you Matt !!"

Air Conditioning questions, answered by experts

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.
