A dead furnace on a cold night isn't an inconvenience - it's an emergency with pipes on the line. We repair fast and replace honestly.
Furnaces burn fuel in your basement all winter; the margin for sloppy work is zero. Every service includes combustion analysis and CO checks, and heat-exchanger inspections are honest - condemned only with evidence you can see on the camera, never as a sales tactic. That specific scam is why half our customers left their last company.
New installs are commissioned properly: gas pressure set, temperature rise verified, venting and condensate done to manufacturer spec - the difference between a furnace that lasts nine years and one that lasts twenty.
Short-cycling - commonly a dirty flame sensor, choked filter or an oversized unit. The first two are cheap fixes; we'll tell you which you have.
Annually, ideally in fall. It's a safety check as much as a tune-up - small money against midwinter failure and CO risk.
In cold climates, usually yes - the fuel math is real. We'll run your actual usage against both options.
