Portsmouth HVAC questions, answered
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.
What brands do you service in Portsmouth?
All of them. Our 03801 technicians are trained on Carrier, Trane, Lennox, Rheem 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.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in New Hampshire, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
Are your technicians licensed and insured?
Every technician dispatched into Portsmouth is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
