From a dead compressor at 6am to a furnace that won't ignite on the coldest night of the year, AAA Pro HVAC treats every call in Farmington, NH like the emergency it feels like to you.

AAA Pro HVAC didn't start as a franchise rollout or a private-equity roll-up — it started with technicians who got tired of watching homeowners get overcharged for underexplained work.
Our Farmington, NH fleet is stocked daily with the capacitors, contactors, ignitors, and control boards behind most common HVAC failures, so a single visit resolves most calls.

We service central air, packaged units, and ductless mini-splits, and we size every new installation with an actual load calculation rather than matching the old unit's tonnage on a guess. Refrigerant leak detection uses electronic detectors and UV dye, not a repeated top-off that never addresses the actual leak. Techs handling ac repair & installation carry the specific parts and tools this job calls for, not a generic kit.
Every furnace call starts with a combustion analysis and carbon monoxide safety check before any repair recommendation, because a cracked heat exchanger is a safety issue first and a repair line item second.

This is one of the most requested Emergency Ac Repair calls we get across Farmington, NH.
Leaky, disconnected, or undersized ductwork can waste a significant share of a system's output before it ever reaches a vent — we test static pressure and duct leakage rather than sealing blind. Mastic sealing, not just tape, on any duct joint we repair, since tape degrades in attic heat within a couple of seasons.
