"New AC unit in 2016 with recent problem being the third issue with unit since installed. Parts covered by warranty but labor and freon refill not. Most recently coil found leaking and needed to be replaced. I explained to owner past problems including my thought 3 breakdowns was excessive for newer unit. He said he would work with us to get it fixed to our satisfaction and he did just that. I would call them again for HVAC service."

"Our AC went out on Friday afternoon. The Aire Serv repair tech, came out on Saturday morning and told us what we already knew...that our 21 yr old AC unit needed to be replaced. He gave us some tips to help it limp along until we could have a new unit installed. Bill, the Aire Serv sales rep, met us at our house on Monday. We discussed different equipment and options. He was very professional and knowledgeable. He understood we would be getting quotes from other companies and assured us that his pricing be better. After meeting with three other companies, Bill was proven right. Aire Serv was more than $1000 less expensive than the closest competitor for the same Lennox equipment. We signed a contract with Bill on Tuesday afternoon, with the install scheduled two days later on Thursday! The other companies were 2-4 weeks out on installs. The install team (Richard & Justin) arrived promptly at 9am on Thursday and got straight to work. The removal and install was smooth and painless. They finished up around 5pm and spent an additional 45 minutes explaining how the new equipment worked, how to get the most out of the system, and answering our remaining questions. We went from an old, broken AC unit to a complete high-efficiency HVAC system in less than one week. Thank you Aire Serv!"

Boiler Repair FAQs, answered by experts

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

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.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).
