Heating and air conditioning service built around Portsmouth

Nobody in Portsmouth wants to spend a day waiting on a technician with a four-hour window. We quote a 2-4 hours target response time for this ZIP and hold crews locally so that number is realistic.

Local homeowners often run their system harder than the design intended, especially during July and August. That accelerates wear on contactors, capacitors and blower bearings.

Local equipment profile:New Hampshire homes are most often served by boilers, furnaces and cold-climate heat pumps. A long heating season with a short humid summer, and strong demand for ductless retrofits in older homes.

Heating season here is October through April. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Portsmouth03803 HVAC questions, answered

Is my system low on refrigerant, or is it leaking?

Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.

Is my carbon monoxide risk something I should worry about?

With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Portsmouth, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.

How quickly can a technician get to Portsmouth?

For the 03803 service area our target response time is 2-4 hours from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.

How much does an HVAC service call cost in 03803?

A diagnostic visit in Portsmouth typically runs $75 to $150, and that fee is usually applied toward the repair if you approve the work. Repair prices are quoted as a flat rate before we start, so the number you approve is the number you pay regardless of how long the job takes.

Do you charge extra for nights, weekends or holidays?

No. Our pricing in New Hampshire is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.

Do you offer maintenance plans?

We do. A two-visit plan in New Hampshire covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
