Heating Repair Across Livermore

The short answer

Heating repair in Livermore covers gas furnaces, heat pumps, ductless systems and older floor or wall heaters. We identify which system you have, test it for the specific fault, check safety on gas equipment, and explain the repair and price before starting.

Not every Livermore home heats the same way. Newer neighborhoods tend to have a forced-air gas furnace or a heat pump, while some older houses still rely on a floor furnace, a wall heater, or a mix of systems added over the decades. When the heat stops working, the fix depends on which of these you have, and that is where EliteFlow HVAC Repair Service starts. We come from Danville, around 11 miles to the northwest, and repair furnaces, heat pumps in heating mode, ductless units, and older gravity-style heaters throughout Livermore and the rest of the eastern Alameda County area. Cold, clear winter nights in the valley make a dead heating system more than an inconvenience, so we focus on a clear diagnosis, a straight answer about the cost, and a repair that holds up for the rest of the season.

Matching the repair to your heating system

A gas furnace failure is usually electrical or ignition-related: an igniter, flame sensor, pressure switch, or blower motor. A heat pump that is not heating may have a stuck reversing valve, a defrost control fault, low refrigerant, or a thermostat that is not calling for the right mode. Ductless heads fail in their own ways, often sensors or drainage. Older floor furnaces and wall heaters have pilot assemblies and thermocouples that wear out.

Knowing this up front lets us arrive with the right parts on the truck and avoid wasted time.

Heat pump heating problems

Heat pumps are becoming more common across Livermore, and their winter behavior surprises some owners. Air from the vents feels warm rather than hot, the outdoor unit periodically goes quiet and may release steam during defrost, and the system runs longer cycles than a furnace. All of that is normal. What is not normal is the outdoor coil staying encased in ice, cold air blowing for long stretches, or backup heat running constantly.

We check defrost sensors and controls, the reversing valve, refrigerant charge, and thermostat settings. A thermostat configured for a furnace instead of a heat pump is a surprisingly common cause of poor heating and high bills.

  • Outdoor coil frozen solid for hours: defrost or airflow problem.
  • Cool air in heating mode: possible reversing valve or charge issue.
  • Electric bills spiking in winter: backup heat strips running too often.
  • Frequent short cycles: sizing, thermostat placement, or a control fault.

Older homes with floor or wall heaters

Some of Livermore's older houses still have a floor furnace under a grate in the hallway or a wall heater between rooms. These units can last a long time, but their pilot lights, thermocouples, and gas valves eventually wear, and the grates and combustion chambers collect dust and debris. We clean, test, and repair them where parts are available and safe operation can be confirmed.

When parts are no longer made, or the unit shows signs of combustion problems, we explain the alternatives, which range from a ductless heat pump to a small forced-air system, so you can plan rather than scramble.

Gas safety and the Air District rules

Any gas heating repair ends with a check of flame quality, venting, and gas pressure. If we find signs of a damaged heat exchanger or poor draft, we tell you plainly and will not leave an unsafe appliance running.

Homeowners sometimes ask whether new Bay Area Air District rules mean their gas furnace has to go. They do not. The rules apply when an existing furnace fails or is replaced, and from 2029, newly manufactured gas furnaces must meet a zero-NOx standard. If your furnace is repairable, repairing it is allowed; the rules simply shape what you buy when replacement comes.

How to help us help you

Before your appointment, note any error code blinking on the furnace control board, check the filter, and confirm the thermostat batteries and settings. Tell us whether the problem is no heat at all, weak heat, odd noises, or a smell. Those details shorten the diagnosis and get your house warm sooner.

FAQ

Common questions

What types of heating systems do you repair in Livermore?

Gas furnaces, heat pumps, ductless mini-splits, and older floor and wall furnaces, as long as parts are available and the unit can be made safe.

Is it normal for my heat pump to steam outside in winter?

Yes. During defrost the outdoor coil melts frost, and the moisture can look like steam. It should finish within a few minutes.

Why does my heater smell like burning dust on the first cold night?

Dust that settled on the burners or heat strips over summer burns off at first startup. If the smell lasts more than a short while or smells electrical, shut it off and call.

Can my old floor furnace still be repaired?

Often, yes, if replacement parts exist and it passes safety checks. If not, we will lay out replacement options.

Do the Air District rules require me to remove my gas heater?

No. They apply only when existing equipment fails or is replaced. A working furnace can stay.

What other areas do you serve for heating repair?

We also work in Pleasanton, Dublin, San Ramon, Brentwood, and Clayton.
