A reset doesn't fix the underlying cause. A CO check happens on every call, standard, not an upsell.
A short list of components causes most Furnace Repair calls. 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.
Checking for carbon monoxide is baked into the visit itself.
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.
Usually a same-visit fix.
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 Hartwood furnaces with standing pilots have their own failure points that newer ignition doesn't have.
Zero response from the furnace can mean a wiring fault, not a furnace failure to avoid overcharging for parts you don't need.
What happens from your call to heat restored.
Describe the symptom and we route the nearest tech.
Ready to diagnose and often repair same visit.
Combustion analysis happens before any repair is quoted.
Most repairs finish same visit, with a final CO check before we leave.
Feedback from completed furnace repairs.
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
What Hartwood customers ask most.
We verify the actual component rather than assuming from the sound alone.
Yes, it can let combustion gases into breathing air.
You don't pay extra for us to check something that could put your family at risk.
Plenty of companies wave these off; we do not.
A dead furnace jumps the schedule ahead of routine work, even when the calendar is packed with cold-weather calls.
The parts we replace most often ride on the truck already; something unusual might need a quick order and a second stop.
Documentation isn't a special favor, it's standard.
Waiting until it's freezing means a longer wait for a routine visit.
Ask when you call and we will point you the right direction if it is outside our scope.
We dispatch heating techs throughout Hartwood — call to confirm.
