Heat pump or furnace? That is the first thing that matters when the heat quits in Davis, CA, because the two fail in completely different ways. Heat pumps tend to freeze up when defrost stops working, get stuck in cooling when a reversing valve fails, or quietly lean on the electric backup strips, at several times the normal operating cost, when the outdoor unit dies. Gas furnaces usually come down to the flame sensor: once oxide coats it, the burners light but the flame cannot be proven, so the board cuts the gas and locks out after three tries. After that, we most often find cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors at the end of their life.
Fault codes are where our diagnosis starts, not where it ends. On every no-heat call, Davis HVAC backs up the board's story with measurements: flame signal read in microamps, igniter resistance checked, the pressure switch tested against real inducer draft, capacitors and motors metered, and, on heat pumps, refrigerant charge and defrost operation verified. Any visit that touches the gas side also covers the safety basics. We leak-test the connections, look over the heat exchanger, and confirm the flue is drafting, since no heating repair is finished until it has been proven safe.
We service gas and electric furnaces, heat pumps, air handlers, boilers, and ductless systems across all major brands, with igniters, flame sensors, capacitors, inducer motors, and blower motors stocked on the truck, so the majority of repairs finish in one trip. If your equipment is at the end of the road, we say so honestly and walk you through the options with real numbers.

When to Call for Heating Repair in Davis
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:
- A rotten-egg, burning, or musty smell once the heat kicks on
- A heat pump's outdoor unit encased in frost or ice
- Clicking and failed ignition attempts before the furnace gives up
- A loud boom when the burners light, which points to delayed ignition
- Frequent on-off cycles that never bring rooms up to temperature
- Higher heating bills with less comfort to show for them
- Uneven heat, with certain rooms that never warm up
- Cold air, or no air at all, when the thermostat calls for heat
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. Call Davis HVAC at (530) 201-3647 at the first sign of trouble.

The Benefits of Professional Heating Repair
Some of the most dangerous heating failures are the ones nobody notices. A cracked heat exchanger can send combustion gases into the supply air, a blocked or failing flue can spill carbon monoxide into the house, and a furnace that lights late booms gas inside the exchanger, weakening it a little more every cycle. Without instruments, none of it is easy to spot. Even routine symptoms can mislead: a short-cycling furnace may have a bad limit switch, or it may simply be shutting down to protect itself from a choked filter. Clean a flame sensor without asking why it fouled, and the next lockout is already on the calendar.
Instruments and judgment are what our experienced technicians bring to both sides of that problem. We measure the flame signal instead of assuming it, inspect the heat exchanger, verify draft at the flue, and check temperature rise against the data plate so the airflow matches the fire. With heat pumps, the defrost board, sensors, and reversing valve are tested before anyone condemns a compressor, and we look at whether the backup strips have been quietly inflating your bill for weeks. Every repair we finish is proven safe and correct over a full heating cycle, which is the standard you should expect from anyone working on the equipment that keeps your family warm.
Our Heating Repair Process
We follow a proven process to ensure every repair and installation is completed to the highest standards. Here's how we handle heating repair from start to finish:
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.
Clear Findings & Upfront Quote
We show you what failed and why, and give a firm price before work begins. If a cracked heat exchanger or dead compressor changes the math toward replacement, we say so plainly.
Same-Visit Repair
Because we stock igniters, flame sensors, pressure switches, capacitors, and motors, most repairs are finished on the first visit, and your home is warming up before we pack up.
Full Cycle Verification
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.
Not Sure What You Need?
Our experienced technicians can assess your situation and recommend the best solution.

A few simple habits now, like regular filter changes and seasonal tune-ups, can add years to your system's life. Start with these practical measures our team relies on:
- Keep the area around the furnace clear so the burner gets adequate combustion air
- Schedule a professional tune-up every fall before the first cold snap finds the weak parts
- Replace filters monthly through the heating season to keep airflow strong and the heat exchanger from overheating
- Clear snow, leaves, and overgrown shrubs from around the heat pump so defrost works properly
- Keep chlorine products, paints, and solvents away from the furnace, because their fumes corrode burners
- Install a CO detector on each floor and test them every month
- Do not ignore a boom at ignition or a new rattle, since early repairs cost far less
DIY vs. Professional Heating Repair
Online tutorials may help in a pinch, yet lasting repairs and code-compliant installations usually depend on professional methods and trained technicians. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| CO Safety | An unseen hazard never gets tested | Heat exchanger and draft verified |
| Diagnosis | Parts swapped on a hunch | Readings taken before parts are replaced |
| Gas Connections | A loose fitting goes unnoticed | Connections leak-tested with instruments |
| Heat Pumps | Defrost problems misread as total failure | Boards, sensors, and valves tested properly |
| Underlying Cause | Sensor cleaned, cause ignored | The fault behind the fault diagnosed |
| Final Testing | Called fixed after a single cycle | Full cycles run, temperature rise confirmed |
