Heating maintenance is the one service visit built around safety. Anything that burns fuel indoors deserves to be tested once a year.
We inspect the heat exchanger for cracking, test for carbon monoxide in the supply air, verify the flue draws properly, and check that safeties trip when they should. Those four things are the reason to book the visit even in a year when everything seems fine.
After that comes the efficiency work: burner cleaning and adjustment, flame sensor service, blower and motor checks, airflow and temperature rise measured against the manufacturer’s specified range. A furnace running outside its design temperature rise is either wasting fuel or slowly overheating its own heat exchanger.
We recommend booking in the fall, before the first hard freeze, while there is still plenty of room on the schedule.

What the fall visit covers
- Heat exchanger inspected for cracks
- Carbon monoxide testing in the supply air
- Flue and venting draft verified
- Burners cleaned and adjusted
- Flame sensor cleaned, ignition tested
- Safety limits and switches proven
- Temperature rise measured against specification
- Written report of every reading
The four safety checks
Book in the fall, before the first hard freeze. Once the cold arrives, no-heat emergencies rightly come first.
- Heat exchanger
- Inspected for cracking — it is the metal wall between the burner’s combustion gases and the air you breathe.
- Carbon monoxide
- We test the supply air for it rather than assume it is absent.
- Flue draft
- Verified, so combustion products vent outdoors instead of into the house.
- Safety limits
- Tested to make sure they trip when they should.
What happens at a tune-up
- 1
Book a visit
Spring for cooling, fall for heating. Book one or both, with nothing to sign up for.
- 2
We measure
We check charge, amp draws, capacitor values, temperature rise, static pressure and combustion.
- 3
Safety first
We inspect the heat exchanger, test for carbon monoxide, verify the flue draft and test the safety limits.
- 4
Written readings
You get a written record of every reading, which is the paperwork a warranty claim is assessed against.

Before you book
When should I book heating maintenance?
Fall, before the first hard cold snap. Once the temperature drops, everyone calls at once and emergency no-heat calls rightly come first.
Do I need this if my furnace is new?
Yes — and more so than you might think, because most manufacturers require documented annual maintenance to keep the parts warranty valid. A denied compressor or heat exchanger claim costs a great deal more than a service visit.
What is a cracked heat exchanger and why does it matter?
The heat exchanger is the metal wall between the burner’s combustion gases and the air you breathe. A crack lets combustion products — including carbon monoxide — into the airstream. It is not repairable; it means a new heat exchanger or a new furnace, and the system must be shut down until then.
