A reset doesn't fix the underlying cause. A CO check happens on every call, standard, not an upsell.
Furnace failures in Nashua cluster around a handful of parts — ignitors, flame sensors, gas valves, heat exchangers. Each gets tested with a multimeter and combustion analyzer, not replaced on a hunch, not parts-cannon guessing.
What doesn't change from visit to visit.
Every service call ends with a combustion analyzer reading, whether you ask for it or not.
When the temperature drops hard, a dead furnace jumps ahead of tune-ups and non-urgent repairs on the schedule.
A fixed price, set upfront.
We didn't build separate teams for separate fuel types.
Every safety check comes with an actual printed or photographed reading, not just a verbal 'you're fine'.
Six repairs that cover most of our winter calls.
Cracked ignitors and carbon-fouled sensors cause a large share of no-heat calls.
Testing confirms the fault first.
A cracked heat exchanger can leak combustion byproducts into the airflow, not assumption based on age.
Short-cycling or mid-cycle shutdowns often trace to the limit switch or a struggling blower before condemning the control board.
Older Nashua furnaces with standing pilots have their own failure points that newer ignition doesn't have.
We rule this out first to avoid overcharging for parts you don't need.
Four steps, safety checked at every one.
Describe the symptom and we route the nearest tech.
Ready to diagnose and often repair same visit.
Safety checks come first.
Most repairs finish same visit, with a final CO check before we leave.
Recent reviews from winter heating calls.
Home hospice care for my father meant the furnace absolutely could not fail during that stretch of winter. They prioritized our maintenance visit without me even having to explain why.
— F. Adegboyega, family caregiver
Antique shop with a furnace almost as old as some of the inventory. They knew exactly how to work on it instead of pushing a full replacement.
— W. Castellammare, shop owner
Foster three kids and safety is non-negotiable in our house. The CO check came with an actual printed reading, not just a thumbs up.
— N. Ijeoma, foster parent
Converted barn we live in has an unusual heating setup nobody wants to touch. This tech figured it out and fixed the actual problem.
— T. Vukovic, homeowner
Run a small bakery out of our converted garage and the furnace shares a wall with the proofing room, so temperature swings matter more than in a normal house. They understood why that mattered.
— J. Odukoya, home baker
