HVAC
Rooftop air conditioners, furnaces and ducting, diagnosed on site.
The Work
What we do
Heating and cooling fail at exactly the wrong moment — a July afternoon, or the first cold night of a trip. We diagnose the unit where it sits rather than telling you to bring the coach in and leave it for a week.
- Rooftop air conditioners: capacitors, fan motors, control boards
- Furnaces: ignition faults, sail switches, gas valves
- Thermostats and multi-zone controls
- Ducting, vents and airflow problems
- Full unit replacement when a repair isn't worth it

Sound Familiar?
Signs you need this.
- The air conditioner runs but the air isn't cold
- The unit trips the breaker or struggles to start
- The furnace clicks and blows cold, or lights then cuts out
- One end of the rig never gets warm
- A burning or musty smell when it first runs
Any of these and it’s worth a call — (385) 476-1380. We come to you.
Common Questions
Straight answers.
- My RV air conditioner runs but doesn't cool — what's wrong?
- The most common cause is a failed start capacitor, followed by a blocked or filthy coil and then a fan motor on its way out. All three are diagnosable on site in one visit, and the capacitor is an inexpensive part.
- My furnace blows cold air. Is that the gas or the electrics?
- It can be either. A furnace that clicks and blows cold is usually failing to light — ignition, gas valve or a sail switch that isn't seeing enough airflow. We test rather than guess, because replacing a gas valve on a sail-switch fault fixes nothing.
- Is it worth repairing an old rooftop unit?
- Sometimes. A capacitor or fan motor on an otherwise healthy unit is well worth it. A failed compressor on a fifteen-year-old unit usually isn't, and we'll say so rather than sell you the repair.
