Cold air from a furnace is usually caused by an overheating condition that’s tripped the high-limit switch, a failed ignitor that isn’t lighting the burners, a dirty flame sensor that’s shutting down the burner after ignition, or a problem with the gas valve. Each of these has a different fix and a different cost. WireNut diagnoses accurately so you know what you’re dealing with before agreeing to any repair in your Fountain home.

Check the thermostat first: make sure it’s set to Heat and the set temperature is above the current room temperature. Check the breaker for the air handler or furnace. Check the furnace filter, as a severely clogged filter can trigger a safety shutoff. If none of those restore heat, call WireNut. A complete heating failure in a Fountain winter needs a technician, not more troubleshooting.

Yes, potentially. A cracked heat exchanger can allow combustion gases, including carbon monoxide, to mix with the air being circulated through your home. This is a genuine safety concern. WireNut technicians inspect heat exchangers and will tell you clearly if there’s a crack or concern, what the risk level is, and what your options are, including whether the furnace can be safely operated while a decision is made.

Short cycling, where the furnace fires up and shuts down repeatedly without completing a full heating cycle, is usually caused by overheating from a dirty filter or blocked airflow, a failing flame sensor, a tripping high-limit switch, or a control board issue. It can also indicate an oversized furnace that heats the space too quickly. WireNut diagnoses the specific cause in your Fountain home before recommending a fix.

Heating repair costs in Fountain vary based on what’s actually wrong. A simple ignitor replacement is a modest repair. A control board or heat exchanger issue is more significant. WireNut gives you a specific price after diagnosis, before any work starts. We don’t quote ranges designed to get us in the door and then climb once the job is open.

Yes. Heat pump heating failures have their own set of causes, including low refrigerant, a failed reversing valve, defrost cycle issues, or auxiliary heat problems.
