Furnace Repair in Corona — quick answers

My furnace will not turn on at all. What now?

Start with the thermostat batteries and settings, then check for a tripped breaker and a filter so loaded it has shut the system down on a limit. If those look fine, the fault is usually the ignitor, control board or a safety switch, and we should come out.

I smell gas near the furnace. What should I do?

Leave the building right away, take everyone with you, and do not touch switches. From outside, call 911 or your gas utility and let them clear the home. Once they say it is safe, call us and we will inspect the furnace and gas train.

Why does my furnace keep shutting off after a few minutes?

That pattern is usually short cycling on a high limit. A clogged filter, closed vents or a failing blower motor traps heat in the cabinet, so the furnace protects itself. Change the filter, open the vents, and if it repeats we will measure airflow.

What is a flame sensor and why does it fail?

The flame sensor proves the burner actually lit. Over years it builds a film that blocks the tiny current it reads, so the furnace lights, then shuts the gas off seconds later. Cleaning or replacing it is a common, straightforward heating repair.

How quickly can you get to my house in Corona during a summer heat wave?

Call us in the morning and we aim for a same-day arrival window in Corona, including South Corona, Sierra del Oro and the Eastvale side. During a stretch of triple-digit days the calls stack up, so we sequence by whether anyone in the home is elderly, very young or medically vulnerable. While you wait, check that the thermostat is set to cool and has fresh batteries, look for a tripped breaker, and clear any leaves or dust drifts packed against the outdoor unit. Do not open the unit or touch refrigerant lines.

How it works

Step 1
Tell us the symptom
Call or fill out the quote form. We ask what changed, when it started, and whether the outdoor unit is running. That tells us which parts and gauges to load on the truck before we leave.
Step 2
We diagnose on site
We check the thermostat, the electrical side, airflow, refrigerant pressures, and the condenser coil. Desert dust plugs coils and dying capacitors are common. You get the finding in plain words before we touch a part.
Step 3
Repair and verify
We make the repair, then run the system and measure supply air temperature and amp draw so we know it is actually cooling or heating. We tell you what we saw and what to watch for next season.

Why homeowners call us

We know rooftop unitsHalf the valley has a package unit on the roof, baking all summer. We are up there regularly, so we know how those cabinets fail, where the drain pans rust, and how heat and sun break down wiring and blower assemblies.
Dust is the local enemyFine desert dust mats onto condenser coils and chokes airflow, and the system runs hot until something gives up. We check the coil on every call and tell you honestly whether cleaning will fix your cooling problem.
July gets treated like JulyA dead condenser when it is 112 outside is not a routine call. We prioritise homes with no cooling, and we say clearly when we can be there instead of leaving you guessing all afternoon.
Heating tooDesert nights get cold and furnaces sit unused for months. We do heater repair and furnace repair, including no-ignition problems, bad igniters, and blowers that hum without moving air. Same straight explanation, no upsell speech.
