How We Repair Your Rinnai Wall Heater
Furnaces, boilers, heat pumps, radiant systems and space heaters produce heat with burners, elements or a heat pump circuit, protected by safety controls.
We service current and older Rinnai Wall Heater models. Bring the model number to the phone call if you can: it helps us check part availability before we arrive.
Safety first: Install carbon monoxide detectors near sleeping areas. If one sounds, leave the home and call 911.

Is the repair guaranteed?
Yes. Parts and labor are covered by our 90-day warranty. If the same problem comes back within that time, we return and fix it.
Do you work on all Rinnai models?
We repair current and older Rinnai models. Some discontinued parts can be hard to find; if that is the case for your model, we tell you before you pay for a repair.
Should I repair or replace my wall heater?
A wall heater typically lasts about 15 to 25 years. If yours is well inside that range and the repair costs less than half the price of a new one, repairing usually makes sense. Near the end of its life, or when the repair costs more than half of a replacement, replacing is often the better value. We give you an honest opinion either way.
