"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

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.
