Heating Repair Service in Rosemead

The short answer

Rosemead homes use a mix of forced-air furnaces, wall and floor furnaces, and heat pumps, and each type fails differently. SummitAir identifies your system, checks venting and safety controls, and repairs the specific fault so winter heat is dependable.

Heat is something Rosemead residents need for only part of the year, and that is exactly why heating systems here get overlooked. A wall furnace in an older bungalow, a floor furnace under the hallway, a gas forced-air unit in the garage or a heat pump that also does the summer cooling: each can fail in its own way after months of sitting idle. SummitAir HVAC Contractors repairs all of these across ZIP 91770, driving about six miles southeast from Pasadena. This page is organized around the type of heating you have, because the fixes, the safety concerns and the questions worth asking differ quite a bit from one system to the next.

Forced-air gas furnaces

This is the most common setup in houses that have central ducts. When one stops heating, the cause is usually in the ignition sequence: a dirty flame sensor, a cracked hot surface igniter, a stuck pressure switch or a tired inducer motor. Blower problems also come up, especially in units whose motors spent the summer baking in a hot attic.

We trace the sequence of operation to find exactly where it fails, then inspect the venting and the visible parts of the heat exchanger before handing the system back to you.

Wall and floor furnaces in older homes

Many of Rosemead's mid-century houses still rely on a wall heater in the hallway or a floor furnace with a grate in the middle of the house. These units are simple, but they are also old, and their pilot assemblies, thermocouples and gas valves wear out. Dust and debris fall into floor grates and can collect near the burner.

We clean, adjust and repair these heaters when parts are available, and we are honest when one has reached the end of its practical life. If replacement makes more sense, we can discuss a newer direct-vent wall unit or a move to a ductless heat pump, which adds cooling at the same time.

Heat pumps that will not heat

A heat pump that cools fine in summer but struggles in winter often has a reversing valve issue, a defrost control problem, a low refrigerant charge or a thermostat that is not configured correctly. It is also common for a homeowner to see steam rising from the outdoor unit on a cold morning and worry, when it is simply a normal defrost cycle. We test the system in heating mode and explain what is normal and what is not.

Warning signs worth a call

Some heating issues can wait for a regular appointment. Others mean you should turn the system off now.

  • Carbon monoxide alarm activation: leave the house and contact the gas utility or emergency services first
  • Smell of gas near the heater or furnace
  • Scorch marks, soot or melted wiring around a wall heater
  • Pilot light that will not stay lit
  • Heat that comes on and off every couple of minutes
  • Strange rattles, squeals or booming sounds at startup
  • Rooms that stay cold while the thermostat says the system is running

How a repair visit goes

We start with what you have noticed and when it began. Then we inspect the thermostat, the power supply and gas supply, and the heating equipment itself. For gas appliances we check the vent path, combustion air supply and safety switches, and we test for gas leaks at accessible fittings. For heat pumps we check refrigerant pressures, defrost function and backup heat operation.

Once we find the cause, we explain it, outline the repair, and get approval before replacing parts. After the repair, we run the system through several cycles to make sure it starts, runs and shuts off correctly.

If your heating equipment is due for replacement, keep in mind that South Coast AQMD Rule 1111 governs emissions from new gas fan-type central furnaces in this region and is being amended toward zero-emission requirements, so it is worth checking the current rule before buying. Rebates for heat pumps depend on the utility that serves your address. We serve San Gabriel, Temple City, El Monte, Monterey Park and Alhambra as well.

FAQ

Common questions

Do you repair floor furnaces and wall heaters?

Yes. Many older Rosemead homes use them, and we repair pilots, thermocouples, valves and controls when parts are available.

Why does steam come off my heat pump in winter?

That is usually a normal defrost cycle melting frost from the outdoor coil. If the unit ices over completely or stops heating, it needs service.

Is it safe to relight a pilot myself?

If the appliance has clear lighting instructions and there is no gas smell, many homeowners can. If the pilot keeps going out or you smell gas, stop and call.

My heater runs but some rooms stay cold. Why?

With central systems, leaky or disconnected attic ducts are a common cause. With wall heaters, a single unit simply may not reach distant rooms.

Should I replace an old wall furnace or keep repairing it?

It depends on its condition and part availability. We give you an honest assessment and compare repair with options like a ductless heat pump.

How often should heating equipment be checked?

A yearly check before the cool season catches worn ignition parts, dirty burners and venting problems before you need the heat.
