"Part of the cleaners left things undone, have to call and get them to come back to finish. Otherwise, great work on restoration after a fire. They try to get it right and I would use them for the complete project."

"Nathan and his crew were able to accommodate repair and replacement on my water heater and dishwasher plumbing prep. I had a very tight window of time to get this done and they went out of their way to get the jobs done! One of the best service companies I have done business with in the last 50 years! I would highly recommend them to anyone who needs a job done and at a reasonable price, Thank you again Nathan!"

"Great experience with Flame Tech. George was knowledgeable and responsive. He provided an accurate estimate over email based on a number of photos and a few phone conversations which streamlined the bid process considerably. They replaced my AC in a few hours for a fair price and educated me on other safety considerations related to my furnace. He also helped me diagnose a rattle in my air ducts that would have given me fits. Good price, know-how, and customer service, I would use Flame Tech again."

"Joe Gendre was very professional and accommodating. I thought my porch light was bad. He searched until he figured it was the switch. Very polite. He moved some jobs around and what was supposed to be next week service became next day. The lights were out in the bedrooms and bathrooms and for an old lady like me is quite unnerving. Turned out the breaker in the panel was bad and he had to go get one since he didn't have one one his truck.I thought he would be back the next week when he had one. But again to my surprise he went and got one and came right back. I expected to pay at least 25%more and was pleasantly surprised, again, at the out come. I have already given his card to my friend across the street. Thank you for your excellent service Joe. I know this job was not a big one but he treated it like it was."

Heating and Air Conditioning FAQs, answered by experts

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?

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.
