Air conditioning & furnace
Help for an RV that will not cool
Air conditioning is part of our RV repair catalog, alongside furnace work. We handle enquiries about rooftop units that will not cool or start, and furnaces that will not heat or start. Tell us the type of unit and what happens when you try to use it.
A description such as “the fan runs but the air is not cold” is more useful than having to guess which part has failed. If a display shows a message or code, write it down so you can share it when arranging service. You do not need to take the unit apart to describe the symptoms.
Discuss mobile or shop service
Help My RV Repairs offers both mobile RV repair and work at its Peoria shop. Call with your location and unit details to discuss which arrangement is appropriate for the work required.
Peoria, Goodyear and Cave Creek are published service areas. Mobile coverage for the actual address, and current shop availability, should be confirmed before scheduling. Our shop is at 7659 W Hatcher Rd, Peoria, Arizona 85345.
If your concern is an Aqua-Hot system rather than a rooftop air conditioner or furnace, mention that when you call. Aqua-Hot is also listed in our service catalog, and identifying the system helps keep the enquiry clear.
Information to have ready
- Your RV's year, make and model.
- The air conditioner or furnace make and model, if you already have that information.
- Whether the problem affects one unit or more than one.
- What you notice: no start, airflow without cooling, no heat, or an intermittent problem.
- Any displayed fault message, and when the issue started.
- Where the rig is parked and whether you are asking about mobile or shop work.
If you have an extended warranty or an existing manufacturer claim, have the provider and claim details available too. We work with warranty companies and manufacturers, but coverage is determined by the provider and your policy.
