Expert Heater Repair in the Inland Empire
Redlands winters are mild compared to most places, but the cold snaps that do come through still expose a heater that's been neglected all year. Sanborn's has diagnosed and repaired heating systems across the Inland Empire since 1949, and our technicians arrive ready to fix most problems on the first visit rather than scheduling a return trip for parts.
We give you a clear flat rate quote before any work begins, and every repair is backed by our 5 Star Satisfaction Guarantee. If you're not fully satisfied, we make it right.
What Our Heater Repair Covers
We start with a full diagnostic, checking the heat exchanger, burners, ignition system, blower motor, thermostat, and safety controls. We also test for gas leaks and carbon monoxide risk, since these are safety issues, not just comfort ones. Once we know exactly what's wrong, we explain it in plain language, give you an upfront price, and complete the repair with quality parts before testing the system again to confirm it's running safely.
Have questions? We're here to help.
Signs Your Heater Needs Repair
-
Your heater won't turn on or shuts off shortly after starting.
Short cycling can be caused by a failing flame sensor, a clogged filter, or an overheating limit switch. These issues tend to get worse over time.
-
You hear banging, rattling, or grinding when the heater runs.
Banging at startup can point to a delayed ignition problem. Rattling often means a loose component, and grinding usually means metal on metal contact, which needs prompt attention.
-
Your energy bills have gone up without a change in usage or weather.
Rising heating costs with no change in habits often means your system is losing efficiency due to dirty burners, a failing heat exchanger, or a miscalibrated thermostat.
-
Some rooms heat up while others stay cold.
Uneven heating points to a problem with the blower motor, ductwork, or zone controls.
-
You see a yellow or orange flame instead of a steady blue one.
This indicates incomplete combustion, which can also signal a carbon monoxide risk. This should be addressed right away.
