If your furnace has quit and you need it sorted fast, this page tells you what to check in the next few minutes, what is safe to do yourself, and when to hand it to a licensed technician.
Likely causes
In rough order of how often we see them:
- A tripped breaker, a switched-off furnace power switch, or a blown fuse.
- A thermostat set wrong, with dead batteries, or in the wrong mode.
- A clogged air filter choking airflow and tripping the high-limit sensor.
- A dirty flame sensor or igniter that stops the burner from staying lit.
- A blocked condensate drain on high-efficiency units shutting the unit down on a safety switch.
- A gas-supply issue, or a closed gas valve.
Safe checks you can do first
Before booking a visit, rule out the simple things: confirm the thermostat is on and set to heat (fresh batteries help), check that the breaker and the furnace power switch are on, and inspect the air filter — a clogged filter is behind a surprising share of breakdowns. On a high-efficiency unit, a quick look at the condensate drain can save a call. Reset the system once if it has locked out.
When to call a licensed technician
Stop and call a pro for anything involving gas, refrigerant, or internal electrical parts. If you ever smell gas, leave the home and call your gas utility or 911 from outside first. Repeated lockouts, burning smells, or water pooling around the unit all need proper diagnosis rather than guesswork.
What a repair visit actually involves
When a technician arrives, the first job is a real diagnosis — measuring, testing components, and reading any fault history rather than swapping parts and hoping. Once the actual cause is clear, you get an itemised quote before anything is replaced. Most common faults are a same-visit fix; the honest exception is a unit so old or worn that a repair is throwing good money after bad — and we will say so plainly rather than keep selling you parts.
Stopping it from happening again
Most repeat faults trace back to one of two things: a root cause that got patched instead of fixed, or maintenance that quietly fell behind. Once your furnace is running again, an on-schedule filter and one professional tune-up a year are the cheapest insurance against the same call next season. Our maintenance plans make the annual part automatic, and this guide explains how often different systems really need attention.
What to expect when you book
The process is simple and transparent. We start with a few questions to understand what you are seeing and find a visit time that suits you. On site, a licensed technician diagnoses the real cause rather than guessing, then explains it in plain language. You get a clear, itemised quote before any work starts, and we only proceed once you say yes. No surprise line items, and no pressure to add things you do not need.
