The Portsmouth03804 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Thermostat reading several degrees off from reality
Squealing or grinding from the blower assembly
No cool air, or air that is barely cooler than the room
Heat pump stuck blowing cold air in heating mode
Water pooling around the indoor unit or ceiling stains
Skyrocketing utility bills with no change in usage
Heating and air conditioning service built around Portsmouth
A long heating season with a short humid summer, and strong demand for ductless retrofits in older homes. Our Portsmouth teams are set up for exactly that: rapid response, flat-rate pricing quoted before work begins, and no surprise overtime charge for nights or weekends.
In the 03804 area we see a lot of attic-mounted air handlers. Attic heat soak in summer and cold-soak in winter both shorten component life and make insulation checks part of a proper diagnosis.
Peak cooling demand here runs July and August. Booking a tune-up in early spring means you are not competing with the whole neighbourhood for a tech in July.

Portsmouth03804 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.
How quickly can a technician get to Portsmouth?
For the 03804 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.
What brands do you service in Portsmouth?
All of them. Our 03804 technicians are trained on Mitsubishi Electric, Carrier, Trane, Heil and essentially every other residential brand sold in New Hampshire, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Why is my furnace short cycling?
Short cycling in Portsmouth most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Portsmouth see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
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.
