"My heating system wasn’t working properly, so I put the job at Angie’s list and Ray was the first one to call, very professional and he sent his tech (Isiah) right away and was able to remedy the issue in a timely manner. Very happy with the service with Ray’s HVAC and Isiah. Saving their contact details as my HVAC guy from now on."

"ABC Castellos Heating & Cooling came when they said they would and took the time to explain to me the Homeowner, what they were going to do. They also performed a AC System check which they did as part of their service. They also took the time to ask questions about my system. Desmond was very professional. i would recommend them to any one who needs their service."

"We searched for a long time for a company to replace a current central A/C which was not particularly old, but the handler up in the attic was nearing the end of life so we had to replace the whole system. Speer seemed most knowledgeable, offered a product we were comfortable with (Amana) and were also professional and prompt. Of note we had a troublesome smart thermostat which required that they return multiple times to address - they did not consider the job done until this was fully operational. Overall we were very pleased, but the summer will tell!"

"The HVAC tech Jay was everything a homeowner could wish for in a contractor. He called 30 minutes before he was scheduled to arrive to say he was on the way, he was on time, friendly as can be & extremely knowledgeable, hard working & honest. He tried everything he could think of to repair the condenser before telling us it needed to be replaced. He didnâ t do what others would and just give us a price, he gave us options as far as equipment was concerned & the different price points. The folks at AAA HVAC went above and beyond with our system. What started out as a simple Condenser replacement turned out to be needing an entirely new HVAC system because the old system was completely mismatched & undersized for the size of the house & condenser we have, causing all kinds of problems. Including our original condenser dying in under 5 years. Long story shorter, it was an unexpected financial hit and they not only inspected, quoted & replaced everything within a day, they worked with me on financing. Jay even returned the very next day to fill out the invoice with all model & serial numbers that was requested by the manufacturers for any future warranty repairs, just registering the equipment on line was not good enough. I would without a secondâ s hesitation recommend AAA HVAC & Jay. I look forward to working with them on all our Future HVAC needs."

Heating and Air Conditioning questions, answered by experts

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?
