When the heat goes out in Redmond, WA, the clock starts ticking, and the diagnosis depends entirely on what kind of system is doing the failing. On a gas furnace, the single most frequent culprit is a flame sensor coated in oxide: the burners light, the sensor cannot prove the flame, and the board shuts the gas down after the third attempt and locks out. Close behind come cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors that have quietly worn out. Heat pumps fail differently: a weak defrost cycle leaves the outdoor coil armored in ice, a failed reversing valve strands the system in cooling, and a dead outdoor unit leaves the electric backup strips carrying the whole house at several times the operating cost.
Guessing gets expensive on a cold night, so Redmond HVAC treats every heating call as a diagnosis first and a repair second. Our techs measure before they replace anything: microamp flame signal, igniter resistance, pressure switch response to actual inducer draft, capacitor and motor readings, plus charge and defrost checks when the system is a heat pump. On gas equipment, safety checks are built in, not an add-on. Gas connections are leak-tested, the heat exchanger is inspected, and venting is verified, because warm air from an unsafe furnace is not a fix.
Gas and electric furnaces, heat pumps, air handlers, boilers, and ductless systems from every major brand are all on our service list. Because the trucks carry the parts that fail most, including igniters, flame sensors, capacitors, inducer motors, and blower motors, the typical repair wraps up in a single visit. When a system has reached the end of its useful life, you will hear that from us plainly, along with real numbers for each option. Need heat back in Redmond?

Warning Signs for Heating Repair
Spotting the early warning signs gives you the chance to act before the situation spirals into something far more expensive. These are the signals our technicians see most often when a problem is underway:
- The furnace clicking and trying to light but shutting back down
- Cold rooms in one part of the house while others are comfortable
- Higher heating bills with less comfort to show for them
- Strange smells from the vents, especially rotten egg or burning
- Banging at startup caused by burners lighting late
- Thick ice or frost covering the heat pump outside
- No warm air at the registers even with the heat turned up
- Frequent on-off cycles that never bring rooms up to temperature
Don't Wait for a Total Failure
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. If you notice any of these signs, contact Redmond HVAC at (425) 969-4221 for a prompt inspection.
Frequently Asked Questions About Heating Repair
Why Hire a Professional for Heating Repair?
Heating repair carries the highest stakes in home comfort work because combustion is involved. A furnace that lights late booms gas vapor inside the heat exchanger and stresses the metal; a heat exchanger that cracks can pass combustion gases into the supply air; a flue that has stopped drafting sends carbon monoxide into the house instead of out of it, and none of these announce themselves in ways an untrained eye can catch. The diagnostic terrain is genuinely tricky too: a furnace that short-cycles might have a failing limit switch, or it might be protecting itself from a clogged filter, and cleaning a flame sensor without asking why it fouled leaves the next lockout already scheduled.
That is why Redmond HVAC does not work on hunches. Our technicians read flame signal on a meter, look at the heat exchanger directly, confirm the flue is drafting, and compare temperature rise to the data plate so the blower and the fire are properly matched. On heat pumps we check defrost controls, sensors, and the reversing valve rather than blaming the compressor, and we find out whether the electric backup heat has been running unnoticed and driving up your costs. Nothing is called fixed until it has run a full cycle and proven itself safe and correct, because your family's warmth and safety depend on it.
How Our Heating Repair Works
Our systematic workflow delivers thorough, lasting results on every job. Here's what you can expect when you choose Redmond HVAC:
Diagnosis and Safety Check
We pull the fault codes, then verify: flame signal, igniter resistance, pressure switch operation, motor and capacitor health, and charge and defrost on heat pumps, with gas connections leak-tested as standard.
Straight Answers & a Firm Price
Before any repair begins, we walk you through what broke, why it broke, and what it will cost. And if the findings, like a cracked heat exchanger or a dead compressor, point toward replacement, we say so plainly.
The Repair Itself
Most heating repairs wrap up in one trip. The parts that fail most often, including igniters, flame sensors, pressure switches, capacitors, and motors, are already on the truck, so the heat is back on before we head out.
Final Testing
A repair is not done until the system proves itself. That means full cycles, temperature rise checked against the data plate, combustion and draft confirmed on gas equipment, and every safety control verified.

A few simple habits now, like regular filter changes and seasonal tune-ups, can add years to your system's life. Put these technician-approved steps to work around your property:
- Do not ignore a boom at ignition or a new rattle, since early repairs cost far less
- Clear snow, leaves, and overgrown shrubs from around the heat pump so defrost works properly
- Never store paints, solvents, or chlorine products near the furnace; their vapors corrode the burners
- Make sure every level has a working carbon monoxide detector, and test it monthly
- Replace filters monthly through the heating season to keep airflow strong and the heat exchanger from overheating
- Book a fall tune-up so worn parts are caught before the first cold night
- Leave open space around the furnace so the burners can draw enough combustion air
Should You DIY or Call a Pro?
Some simple checks are suitable for DIY, but most heating and cooling repairs benefit from professional tools, training, and experience. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| CO Safety | An unseen hazard never gets tested | Draft and heat exchanger checked every visit |
| Diagnosis | Parts swapped on a hunch | Flame signal and components metered |
| Gas Connections | A loose fitting goes unnoticed | Instrument leak testing as standard |
| Heat Pump Faults | Defrost problems misread as total failure | Defrost controls and reversing valve tested |
| Root Cause | Quick fix, same failure next week | The fault behind the fault diagnosed |
| Final Testing | One successful start and done | Complete cycles tested against the data plate |
