Run through a few quick checks, look up an error code, or find out how old your equipment actually is. Most of this takes two minutes, and it often saves you a call.
Tap each one as you go. Any of these can be the whole problem.
Set to Heat (or Cool) and a temperature past the room's current reading? Screen blank or dim? Try fresh batteries.
Look for a breaker labeled Furnace, AC, or HVAC sitting slightly off from the others. Switch it fully off, then back on.
Most furnaces have a switch near the unit that looks like a regular wall light switch. Make sure it's flipped on.
A filter clogged grey with dust can shut the whole system down as a safety precaution. Replace it if it's caked.
High-efficiency furnaces and AC units drain condensation through a small pump or line. A clog or full pan can trip a safety switch and shut things down.
Most furnace control boards blink a pattern when something's wrong. You don't need to decode it — just note the pattern, or look it up in the Error Codes tab.
Search by code, brand, or just describe what you're seeing.
The serial number tells you the manufacture date — and whether repair or replace makes more sense.
Estimates use each manufacturer's published date-code format and aren't a substitute for an on-site inspection — very old or relabeled units can decode ambiguously. We're happy to confirm in person.
Our techs can usually tell what's going on over the phone. No charge to ask.
