Safety-first diagnostics
Every heating call starts with a combustion and CO check. If we find a cracked heat exchanger, you'll hear it straight.

Frequently Asked
Heating & Furnace Repair questions,
answered honestly.
Why is my furnace blowing cold air?
+
Most often a flame sensor issue, failed igniter, low gas pressure, or a stuck safety switch. Sometimes it's just a thermostat set to 'fan on' instead of 'auto'. We'll diagnose it in one visit.
How often should a furnace be serviced?
+
Once a year, ideally in fall before the first real cold snap. A short annual tune-up dramatically reduces mid-winter breakdowns.
Is it safe to keep running a furnace that's making noise?
+
It depends on the noise. Rattling can be a loose panel; booming on ignition can point to delayed ignition — a real safety concern. Turn it off and call us if you're unsure.
Do you service heat pumps too?
+
Yes. Heat pumps, dual-fuel systems, and straight electric furnaces are all part of what we do year-round.
