Rating: 5 out of 5 stars★ ★ ★ ★ ★☆ ☆ ☆ ☆ ☆The technician Jose, was easy to work with and thoroughly checked and cleaned our systems. He suggested some preventative maintenance actions to make sure our 9 year old furnace and 7 year old AC would last another few seasons. Jose replaced a capacitor and contactor in the nick of time – we sailed through a recent heatwave with our AC running like new! Highly recommend Aire Serv.

Rating: 5 out of 5 stars★ ★ ★ ★ ★☆ ☆ ☆ ☆ ☆This summer, both my furnace and thermostat died with 90 degree temps outside. Jillian and her team came out quickly, replaced my furnace and thermostat and brought the temperature in my house from 84 back to 68! The pricing was VERY reasonable, the customer service was EXCEPTIONAL, and the follow up was both unexpected and FANTASTIC! Throughout the entire process, Jillian's knowledgeable team gave me all of my options as well as their suggestions. They took away my stress about this situation as I knew I was in great hands. I would enthusiastically recommend Air Serve to anyone and everyone!

Rating: 5 out of 5 stars★ ★ ★ ★ ★☆ ☆ ☆ ☆ ☆Jillian is the best HVAC co-ordinator, never observed this professional and timely communications from any HVAC Company. Email communications means nothing without the Quality of Technicians who do the actual work in a timely and professional manner. Techs who completed the job over two distinct visits seemed in synch with Aire Serve's objective of eliminating nonsense from HVAC business. The prices they offered were endorsed by Gemini AI; fair with reasonable Premium, of course.

You’ll receive written details on parts, labor, and timing to ensure complete clarity. During every job, your local service professional walks you through the diagnosis and provides a side-by-side breakdown of costs for a quick fix compared to a full repair or upgrade.

-
Should your furnace turn on and off too often (short cycling) or certain areas never reach the set temperature, it’s likely a sign of a performance issue. Faulty sensors, dirty filters, or blower problems are common culprits, often fixed through a furnace tune-up or repair. If your carbon monoxide alarm sounds while the furnace is active—or you spot soot by registers, rust on the flue, or heavy window condensation—treat it as a safety emergency. Turn off the system, allow fresh air in, and call for emergency HVAC service immediately. In the event of any of these indicators, a professional tune-up and furnace cleaning can help restore efficiency, stabilize temperatures, and prevent surprise shutdowns. If your system is more than 15 years old, requires frequent repairs, or the repair cost is nearing half the price of a new unit, it might make sense to consider a replacement. A professional evaluation can help you weigh efficiency improvements and overall costs for furnace replacement in Techny.
