Heater & Furnace Repair in Granada Hills, CA
Closet and garage furnaces are the norm in Granada Hills, and many of them are older standard efficiency units. We check the burners, igniter, flame sensor and venting, and test for carbon monoxide on every heater call.
Furnace repair in Granada Hills: closet and garage furnaces
Most requests for furnace repair in Granada Hills come from the 1950s to 70s ranch homes that make up much of the area. In these houses the furnace usually sits in a hall closet or in the garage, and the ducts run through a low attic. Many of those furnaces are standard efficiency models that vent through a metal flue. A smaller number of homes still have an original floor furnace. Knollwood and the hillside streets near O'Melveny Park add guest houses and studios with their own heat.
Common heating failures in Granada Hills homes
- Burners light, then go out. A dirty flame sensor, or on older units a weak thermocouple.
- Furnace overheats and short cycles. Closet furnaces often have small return grilles. Add a dirty filter and the furnace trips its limit. See furnace short cycling.
- Loud blower or no blower. Worn motor bearings and failed capacitors on older belt or direct drive blowers.
- Garage furnace safety. A furnace in the garage must sit up off the floor and have the right protection. We check the platform, the gas line and the flue.
- Flue problems in the closet. We make sure exhaust gases go up the vent and do not spill back into the hallway.
Floor furnace repair in Granada Hills
Original floor furnaces still turn up under hallways in older homes. They collect dust and debris through the grille. We clean them, check the pilot, valve and limit, and test for carbon monoxide. If a floor furnace is not safe to keep, we tell you plainly and explain the options. See wall and floor heaters.
Repair or replace?
A closet furnace of 20 years or more that needs a heat exchanger, or an old furnace with an AC that is also failing, is the time to look at a new system. A heat pump air handler fits in most of the same closets and covers both heating and cooling. Granada Hills is in the City of Los Angeles, so a replacement is permitted through LADBS, and we handle that. See furnace installation or furnace repair.
Carbon monoxide: what to do
If your CO alarm goes off, do not look for the cause. Get everyone out of the house, call 911, then call SoCalGas. Call us once the fire department or the gas company says it is safe to go back in. Every heater repair we do includes a carbon monoxide test and a look at the flue and gas connections.
Safe checks before you call
- Thermostat set to Heat, a few degrees above room temperature, with fresh batteries if it has them.
- Look at the filter. If it is gray and packed, replace it.
- Check the breaker and the service switch next to the furnace (it looks like a light switch).
- Make sure the furnace door or panel is closed tight. Most furnaces will not run with it loose.
- Clear the hall closet around the furnace. Boxes and coats against it block the air it needs to burn safely.

Frequently asked questions
Can my closet furnace be replaced with a heat pump?+
In most cases yes. A heat pump air handler fits in the same closet and gives you heating and cooling in one system.
Do you repair floor furnaces in Granada Hills?+
Yes, with a full gas safety check.
Is it safe to store things in my furnace closet?+
No. A gas furnace needs air for combustion and space for service. Keep the closet clear, and never store paint, cleaners or anything flammable there.
My Granada Hills furnace is in the garage. Does it need anything special?+
Gas furnaces in garages normally need to be raised off the floor and protected from car impact. We check this on every visit and tell you if anything is missing.
How far is Granada Hills from your base?+
Just over the Newhall Pass from Santa Clarita, so same day service is common.
How fast can you come?+
Same day in most cases, 24/7 for emergencies.
Do you check for carbon monoxide?+
Yes, on every heater call.
