RV Furnace Repair
A furnace that won't light on a cold morning is more than an inconvenience. We come to your rig and get the heat back, most jobs the same day. Mobile furnace repair for Suburban, Atwood, and Dometic across the Tampa Bay area.

What we fix
Blower, sail switch, igniter, gas valve, or thermostat: every common RV furnace fault, diagnosed on-site and fixed same-day when we can.
Blower runs, then it clicks and quits without lighting, classic sail switch, igniter, or gas-valve trouble.
Fan runs but the burner never lights: the furnace is moving air without making any heat.
No fan, no heat, a failed blower motor, a control-board fault, or low battery voltage.
Lights, then shuts off in a minute or two, often a sail switch, a dirty flame sensor, or restricted airflow.
Furnace is fine but won't call for heat, a thermostat, wiring, or control-board issue.
Barely-warm vents or a rattling blower, a wheel, bearing, or ductwork problem.
Seeing something that's not on the list? We've almost certainly fixed it before.
Tell us what's happeningWhat's included
We test the whole sequence (thermostat, blower, sail switch, igniter, flame sensor, and gas valve), find where it breaks, and repair it on-site so the furnace lights and stays lit.
Most no-heat calls trace to a dirty burner, a bad sail switch, or a blower starved for air. We clean and test the burn, check airflow, and catch the small stuff before it leaves you cold.
Good to know
Here's the sequence every RV furnace follows: the thermostat calls for heat, the blower spins up, and only once the fan is moving enough air does a little paddle called the sail switch close and allow the igniter and gas valve to fire. That safety step is the #1 reason a furnace “won't light.” If the blower is weak, the intake or exhaust is blocked (mud daubers love these), or the sail switch itself is bad, the furnace runs the fan and then quits without lighting, exactly what most owners describe. It's usually a cheap fix once you know to look there, and it's the first thing we check.
If the fan runs but you're getting cold air, the furnace is failing after the blower step, so the problem is downstream: a sail switch that isn't closing, a dirty or failed igniter, a weak flame sensor, a gas-supply problem, or a bad gas valve. If the blower doesn't run at all, it's the other direction: a blower motor, a control board, a thermostat, or (very commonly) low battery voltage, because RV furnaces pull a lot of 12-volt power to run that fan. We diagnose which half of the sequence failed and fix the actual cause, not just the symptom.
RV furnaces sit unused for months, and that's when trouble sets in. Before the first cold night: make sure the exterior intake and exhaust vents are clear (wasps and mud daubers block them constantly), check that your batteries are healthy since the blower is power-hungry, and run the furnace for a full cycle so you find a problem at home, not at 2 a.m. in the cold. If it lights slow, short-cycles, or smells off, have it looked at before you rely on it: a sail switch or flame-sensor cleaning is a small job next to a no-heat night.

“I was caught in a jam at the KOA campground in St. Petersburg when my air conditioner unit was throwing a faulty code. After calling multiple people, Jared assured me he would be there as soon as possible to help since it was so hot outside. Jared showed up within 20 minutes of the call and had the issue fixed in less than that. He was professional, knowledgeable, and was fair with his pricing!”
