Heating Repair Across Antioch

The short answer

We repair every common heating system in Antioch homes, including gas furnaces, heat pumps, wall heaters and ductless units. Each visit starts with a full diagnosis and ends with a safety check and a working system.

Heat in an Antioch house can come from several places: a gas furnace in the attic, a heat pump on the side yard, a wall heater in an older bungalow, or a ductless head in a converted garage. When one of them stops working on a cold, foggy morning, you want someone who can sort out which part of the system failed and fix it without a lot of trial and error. We provide heating repair throughout 94509 and 94531, traveling about 14 miles northeast from Danville. The sections below describe the heating systems we repair here, the questions we ask when you call, and what you can expect from the visit itself.

Heating systems we repair in Antioch

The housing stock here ranges from older single-story homes to newer subdivisions, and the heating equipment varies just as much. We work on all of it.

  • Gas forced-air furnaces, standard and high-efficiency, in attics, garages and closets
  • Heat pumps that will not switch into heat mode, freeze up or run constantly
  • Ductless mini-splits with error codes, weak output or noisy indoor heads
  • Gas wall heaters and older floor furnaces found in some original homes
  • Thermostats, zone controls and wiring that keep a sound system from responding

Questions we ask when you call

A few details help us arrive with the right parts and a clear idea of the problem. What kind of system do you have, and where is it located? Is there no heat at all, or is it weak? Does the indoor fan run? Do you hear clicking, humming or a whoosh of gas lighting and then nothing? Is there a code flashing on the equipment or the thermostat?

If you are not sure, that is fine. A photo of the equipment label or the thermostat screen can also help, and we will figure out the rest on site.

Heat pump heating problems

More Antioch homeowners now heat with heat pumps, and those systems have their own failure points. A reversing valve that sticks leaves the system blowing cold air when it should be heating. A defrost board or sensor that fails lets ice build up on the outdoor coil until airflow stops. Low refrigerant from a slow leak reduces heating output long before the system quits outright.

During a cold snap, a light layer of frost and short defrost cycles with a bit of steam are normal. A unit encased in solid ice, or one that never seems to defrost, needs a technician. We test the defrost controls, reversing valve operation and refrigerant charge to pin down the cause.

Older wall heaters and floor furnaces

Some older Antioch homes still rely on gas wall heaters or a floor furnace set into the hallway. These units are simple, but age brings real concerns: worn thermocouples, dirty pilot assemblies, failing gas valves and venting that may have shifted over the decades. We clean and repair these heaters where it is safe to do so, and we check venting and combustion every time.

When a heater is past saving, we explain the alternatives, which often include a ductless heat pump for that room or the whole house. Air District rules do not force replacement of working equipment, so you can plan the change on your own timeline.

One cold bedroom, one warm hallway

Not every heating complaint is a broken part. A common Antioch call goes like this: the furnace or heat pump runs fine, the thermostat reaches its setting, yet the back bedroom or the room over the garage stays several degrees colder than the rest of the house. The cause is usually in the air path rather than the equipment.

We look at the ducts that feed the cold room for crushed or disconnected flex runs in the attic, check whether a damper was closed years ago and forgotten, and measure how much air actually reaches the register. Return air matters as much as supply; a bedroom with the door shut and no return path can starve itself of warm air. Fixes range from reconnecting a loose run to adding a jumper duct or a small ductless head for a room that was never served well. We explain which option fits before any work begins, so you are not paying for equipment when a duct repair would do.

How the visit ends

Once the repair is finished, we run the system through several complete cycles, check temperature rise or supply temperature, confirm the thermostat controls it correctly, and test for carbon monoxide around gas equipment. You get a clear summary of what we found, what we fixed, and anything we recommend watching. We bring the same approach to heating calls in Brentwood, Clayton, Concord, Walnut Creek and Pleasant Hill.

How a visit goes

    We show you the failed part or the reading that points to it, and explain what it means for the rest of the system.

  2. Choices, not pressure

    Repair, replace or wait and watch: you get the trade-offs of each and make the call yourself.

  3. Care for your home

    Shoe covers, drop cloths and a clean work area when we leave, whether the job was in the attic, garage or hall closet.

FAQ

Common questions

My heat pump is blowing cold air. Is it broken?

Not necessarily. During a defrost cycle, a heat pump can briefly blow cooler air. If it continues for more than a few minutes, the reversing valve, defrost controls or refrigerant charge may need attention.

Do you repair old floor furnaces?

Yes, when the unit can be repaired safely. We clean and replace worn parts and always check the venting and combustion before putting it back in service.

How fast can you get heat back on?

Many repairs, like ignitors, flame sensors, thermocouples and capacitors, are done on the first visit. Some parts must be ordered, and we tell you the timeline right away.

What if my thermostat is the problem?

We test thermostat wiring and settings as part of every heating diagnosis and can repair or replace the thermostat if it is the cause.

Do you offer heating repair outside Antioch?

Yes. We also serve Brentwood, Clayton, Concord, Walnut Creek, Pleasant Hill and our home base in Danville.
