We Fix the Reason It Quit, Not Just the Part That Failed
We Take Readings, Not Guesses
Gas pressure, temperature rise across the heat exchanger, amp draw on the blower, and microamps on the flame sensor. Those numbers tell us whether a part failed on its own or something else killed it.
Safety Comes Before the Repair
We check the heat exchanger, the flue draft, and the gas connections on every heat call. If we find a cracked exchanger or a backdrafting flue, we shut it down and show you what we found before anything else.
Parts on the Truck
Ignitors, flame sensors, limit switches, capacitors, and common blower motors ride with us. Most no-heat calls get solved in one visit instead of turning into a three-day wait for a part.
One Price, Agreed up Front
You get the number before the work happens. If the repair turns into a replacement conversation, we lay out both costs and let you decide without a sales pitch.
What People Say After the Truck Leaves
"Furnace quit on the first cold night in December. They came out that evening, found a bad ignitor, and had heat back on in under an hour. Told me the price first, which I appreciated."
"Our old unit kept shutting off after a few minutes. Turned out the flame sensor was coated and the filter was choked. Cleaned both, showed me the reading, and it's run fine since."
"They checked the heat exchanger with a camera and showed me it was fine. Another company had told me it was cracked and quoted a whole new system. Honest people."

How We Actually Troubleshoot a No-heat Call
Most heating repairs come down to one of a handful of failures, but the trick is figuring out which one before you start replacing parts. A furnace that lights and then shuts off after thirty seconds is telling you something different than one that never lights at all, and a heat pump blowing cool air has nothing in common with either. We start by watching the unit run through a full cycle and reading what it does at each step.
From there the sequence is the same every time: verify the thermostat is calling, confirm power and gas at the unit, watch the ignition sequence, then take readings while it runs. Here is what we check on a standard gas furnace call:
- Thermostat call and control voltage at the board, so we are not chasing a furnace problem that is really a wiring or battery problem.
- Ignitor resistance and the glow pattern, since a weak ignitor often lights for months before it quits entirely.
- Flame sensor microamps, which is the single most common cause of a furnace that lights and then drops out.
- Gas manifold pressure against the rating plate, because an underfired unit never satisfies the thermostat.
- Temperature rise across the heat exchanger, which exposes airflow problems hiding behind a heating complaint.
- Inducer and pressure switch operation, along with the flue for any sign of blockage or backdraft.
- Blower amp draw and capacitor value, since a struggling motor can trip the limit and mimic a dozen other faults.
What breaks around here and why
Our heating season is short, which is exactly what causes trouble. A furnace that sits idle from March to November collects dust on the burners and the flame sensor, and the first cold night is when everybody finds out. That is why the December calls come in waves. If your system has been off all summer, the odds of a dirty sensor or a stuck inducer are high.
Airflow is the other big one. We commonly see issues with airflow due to air ducts that need repairing, especially in East Highlands Ranch where the homes are larger and the duct runs are long. A restricted return makes a furnace overheat and trip the high limit, and homeowners read that as a broken furnace when the real problem is a crushed flex duct in the attic or a filter nobody changed since spring.
Up closer to the base of the San Bernardino Mountains we also deal with heavier dust and, in a few pockets, older wall and floor furnaces still in service. Those units need a different set of eyes. Parts are scarce, safety margins are thinner, and we will be straight with you when a repair no longer makes sense on a unit that old.
What a heating repair visit looks like
- 1
You Call and We Set a Real Window
A person answers, gets the symptoms, and gives you an arrival window we intend to keep. No-heat calls get moved to the front.
- 2
Full Cycle Diagnostic
We run the system and watch every stage, taking electrical, gas, and temperature readings instead of swapping parts to see what sticks.
- 3
Safety Inspection
Heat exchanger, flue draft, and gas connections get checked on every visit. If something is unsafe, you hear about it before you hear a price.
- 4
Written Price, Your Call
We explain what failed, what it costs, and whether the rest of the system is worth the repair. You decide, then we work.
- 5
Repair, Verify, and Clean Up
After the fix we run another full cycle and recheck the readings, so you know the number moved. Then the workspace goes back the way we found it.
Repair or replace, told straight
A repair usually makes sense when the unit is under fifteen years old, the heat exchanger is sound, and the fix costs a fraction of a new system. It stops making sense when you are stacking a second or third major repair onto a unit that is already past its service life, or when the heat exchanger has cracked. We give you the numbers for both paths and let you pick, because pressuring somebody into a system they did not budget for is not how you keep a customer in a town this size.
If your furnace is limping along right now, the cheapest move is usually a tune-up before the cold hits, not an emergency repair at 9pm. Highland Heating & Air keeps the diagnostic price flat at $75 for homes so there is no reason to put off finding out what is actually wrong.

Heating Repair Questions, Answered
Nine times out of ten it is the flame sensor. A thin layer of oxide builds up on the rod, the control board stops seeing flame, and it shuts the gas off as a safety response. Cleaning or replacing the sensor is a short visit, and we check the microamp reading afterward to prove it took.
That is normal after a long off season, which around here means March through November. Dust settles on the heat exchanger and burns off in the first cycle or two. If the smell lasts more than a few cycles, or smells sharp or electrical instead of dusty, shut it down and call us.
You usually cannot tell by looking from the outside, which is why we inspect it with a camera and check combustion readings. Warning signs include the burner flame moving when the blower kicks on, soot around the burners, or a carbon monoxide alarm. A cracked exchanger means the unit gets shut off, no exceptions.
Not necessarily. Heat pumps deliver air cooler than a gas furnace does, so it can feel wrong even when it is working. It also runs a defrost cycle on cold mornings that briefly blows cool. If the house is not holding temperature or the outdoor unit is iced over hours later, that is a real fault worth a visit.
We run 24/7 and no-heat calls jump the line, so same-day is normal and evening calls in the Redlands and Yucaipa area are routine during a cold snap. When the first freeze hits and everyone calls at once, we give you an honest window rather than a promise we cannot keep.
Sometimes, if the repair is small and the heat exchanger is sound. Once you are into a blower motor or a control board on a unit that age, the money is usually better spent on a replacement that comes with a warranty. We price both so you can compare instead of taking our word for it.
