HVAC Service & Repair | Derry, NH

🛠️

When your HVAC system stops working, you need a licensed technician who can get there fast and diagnose the problem correctly. The Air Department handles heating and cooling repair for homeowners throughout Derry, NH and southern New Hampshire. Brad answers his own phone, gives you a straight diagnosis, and does the work himself.

The most common HVAC service calls Brad handles in the Derry area include furnaces that will not ignite, heat pumps that have stopped producing heat, AC units that are running but not cooling, and systems that cycle on and off without reaching the set temperature. Many of these issues come down to a dirty filter, a faulty sensor, or a worn component that is inexpensive to replace if caught early. Brad will tell you what is wrong and what it costs to fix before any work begins.

Older HVAC equipment in New Hampshire often runs into problems that are not immediately obvious. A system that seems to be working may be running at reduced efficiency because of a cracked heat exchanger, low refrigerant, or a dirty evaporator coil. These issues drive up your energy bills before they cause a visible failure. Part of Brad's diagnostic process is looking for these hidden inefficiencies, not just the immediate symptom that caused the service call.

Brad services all major equipment brands and all fuel types including natural gas, propane, and oil. He carries common replacement parts on his truck so that many repairs can be completed in a single visit. If your system needs a part that requires ordering, Brad will be upfront about the timeline and keep you informed. No runaround, no upselling parts you do not need.

Common Questions About HVAC Service & Repair in Derry, NH

How quickly can you respond to an HVAC repair call in Derry, NH?

Brad is based in Derry and handles most service calls the same day or next morning. For urgent situations in the middle of winter or during a heat wave, call or text (603) 315-7227 directly. He answers his own phone and will give you a realistic time.

What are the most common signs my HVAC system needs repair?

Unusual noises (banging, squealing, rattling), the system running but not reaching the set temperature, short cycling (turning on and off repeatedly), unusually high energy bills, or the system not turning on at all. Any of these are worth a service call before the problem gets worse.

Do you service all HVAC brands?

Yes. Brad services all major residential HVAC brands including Carrier, Trane, Lennox, Rheem, Bryant, and others. He also services Mitsubishi and other mini split brands. If you are not sure whether he works on your equipment, call and ask.

Is it worth repairing an older HVAC system or should I replace it?

It depends on the age of the equipment and the cost of the repair. A general rule: if the repair costs more than half the price of a new unit and the system is over 15 years old, replacement usually makes more financial sense. Brad will give you his honest read on both options during the service call.
