In a lot of Culver City houses, the air conditioner and the furnace are really one machine. They share a blower, a thermostat, a control board and the same ducts. So when HVAC repair is what you need, the part that failed may be the one both systems lean on, and one visit can put heat and cooling back together.
How the repair price is set
We do not quote a repair over the phone, because the same complaint can trace to a part worth very little or to one that costs real money. The number comes from three facts we gather at your house.
- The failed part. A capacitor and a control board sit at very different price points.
- The labor to reach it. A unit in a hall closet opens in minutes. One in a low attic or under a floor takes longer.
- Whether the part is on the truck. Common capacitors, contactors and fan motors travel with the technician. A board for an uncommon model may need ordering.
You see the failed part, you hear what it does, and you get the price in writing before anything is swapped. If you decline, nothing gets changed. Describe the symptom and which system quit through the repair booking form, and we will send a technician carrying the parts that symptom usually calls for.
Shared parts that stop heat and cooling together
These are the components we test first when a whole system goes quiet, because a fault in any of them takes down both modes.
- Blower motor and its capacitor. The same fan pushes warm air in winter and cool air in summer. A weak capacitor can leave it humming without turning.
- Control board. It tells the blower, the burners and the outdoor unit when to run. A failed relay on the board can stop everything at once.
- Thermostat and its wiring. A dead thermostat or a broken wire at the air handler cuts the signal to both systems. Upgrading to a smart thermostat is an option once the wiring is sound.
- Condensate safety switch. Many systems shut down when the drain pan fills, to keep water off the ceiling. A clogged drain line is a common reason a system trips off in summer.
- Transformer and fuse. A small electrical fault here kills the low-voltage side of the whole setup.
These parts ride on the truck, so the repair can be finished in one visit. When a part has to be ordered, we tell you the day it arrives and come back to finish.
What to tell us when you book
The more we know before we arrive, the better the odds we leave with the system running. A few details help.
- Which mode failed. Cooling only, heating only, or both.
- What it does now. Silent, humming, blowing room air, short cycling or tripping a breaker.
- Where the equipment lives. Attic, garage, hall closet or a floor furnace under the house.
- The brand on the label, if you can read it without moving anything.
That short list lets us load the truck for your call, not for a generic one.
When only one side has failed
If the furnace still heats and only the cooling has stopped, the fault is often outdoors at the condenser: a contactor, a capacitor, a fan motor or a refrigerant leak. Our AC repair visits start at that unit.
If the AC still cools but the heat will not come on, we look at the burner side: igniter, flame sensor, pressure switch or gas valve. Our heating repair team handles those calls the same way, with the part named and priced first.
Either way we test the shared parts too, because a weak blower capacitor can fail in the other season next.
If you smell gas, leave the house before anything else and call SoCalGas or 911 from outside. Then call us once the utility clears it.
Repair first, and when we raise replacement
Our default is to fix what broke. We raise replacement only when the repair stops making sense, such as a cracked heat exchanger on the furnace or a failed compressor on an older system that still runs R-22. R-22 is no longer produced, so those repairs depend on reclaimed refrigerant. In those cases you get two written options, the repair and the replacement, and you pick.
FAQ
Can one technician fix both my AC and my furnace?
Yes. The technician tests the shared blower, board and thermostat, then the heating side and the cooling side. If both need work, both go on the same written estimate.
Why did my heat and AC stop at the same time?
Usually because a shared part failed: the blower motor, its capacitor, the control board, the thermostat wiring or the condensate switch. We find which one on the first visit.
Is a humming air handler worth a call?
Yes. A hum with no airflow often means a capacitor or motor problem. Running it that way can overheat the motor, so switch it off and book the visit.
Do you work on floor furnaces and attic units?
Yes. Access changes the labor, so tell us where the unit is when you book. It goes into the written price.
What happens if the part is not on the truck?
We order it, tell you when it arrives and come back to install it. The price you approved stays the price.
