On a Bel Air estate, the AC and furnace replacement cost is worked out one zone at a time. Each wing can have its own pair: a furnace or air handler inside, and a condenser outside that cools through a coil on top of the furnace. When one half of that pair fails, the question is whether to replace it alone or do both together. Bel Air Cooling prices that choice for you on paper.
What the pair costs on one zone
For the cooling half, a new SEER2-rated system starts around $5,000 installed, depending on tonnage and access difficulty.
For the heating half, our own service pricing shows what a furnace costs on its own: Regular maintenance typically costs between $109 and $340 in Bel Air, but it protects a furnace that can cost $4,000 to $7,000 to replace.
Your number for the pair depends on the size of the zone, the type of heating you pick and how hard the two units are to reach. To get it, send the zone, the age of each unit and a photo of the furnace closet or attic through the replacement quote form. We confirm the details on a visit and write both halves on one quote.
Both halves at once, or one at a time
The furnace and the AC share parts. The indoor coil sits on the furnace, and the blower in the furnace moves the cooled air. That is why replacing both on the same visit often makes sense.
| Choice | When it fits |
|---|---|
| Replace both together | Both units are old, the coil is tied to the failing AC, or you want one permit and one install day for the zone |
| Replace the AC only | The furnace is newer and its blower suits the new outdoor unit |
| Replace the furnace only | The AC was recently replaced and the coil matches the new furnace |
When you split the job, the half you keep has to work with the new half. We check the coil, the blower and the controls before we tell you a single-side swap is sound. If they do not match, the quote says so and shows the price of doing both.
What changes the price on an estate zone
Four things move the pair price the most in Bel Air homes.
- Where the furnace sits. Many older estates have furnaces in crawlspaces or attic platforms. Tight spots add labor to remove the old unit and set the new one.
- Where the condenser sits. Side yards are simpler than hillside pads, roofs or spots behind a landscape wall.
- The zone's load. A wing with tall ceilings and glass needs more capacity than a bedroom suite.
- The gas and venting side. A new furnace may need its gas connection or flue changed to fit.
Replacing a furnace or AC in California is permitted work. In Bel Air, LADBS issues the permit, and it is a line on the quote.
When a repair quote should become a replacement quote
Many calls start as a repair. A furnace stops lighting, or the AC runs but the zone stays warm. We diagnose it and give you the repair price first.
The line we use is simple. When an aging system needs a repair over $800, replacement usually makes more financial sense. On those visits, we put the repair price and the replacement price for the zone side by side, and you choose.
Some repairs end that conversation fast. A furnace with a cracked heat exchanger is taken offline, because it can leak carbon monoxide into the house. Most owners replace the furnace at that point, and we quote the AC with it if the coil and condenser are near the same age. For a furnace that still has life in it, heating repair is the right call, and we say so.
Gas furnace or heat pump for the heating half
You do not have to replace a gas furnace with another gas furnace. A heat pump can take over both heating and cooling for the zone, with one outdoor unit doing both jobs.
- A gas furnace keeps your SoCalGas service and pairs with a new AC condenser and coil.
- A heat pump runs on electric service from LADWP and replaces both the furnace burner and the AC.
We quote both options when they fit the zone, with the same line items, so you can compare. The heating installation page covers the furnace and heat pump equipment we install, and AC installation covers the cooling side.
FAQ
Should I replace the AC and furnace at the same time?
If both are old, usually yes, since they share the coil and the blower. If one is newer and matches, a single-side swap can work. We check that before we quote it.Can each zone on the estate be done on its own schedule?
Yes. Each zone has its own pair of units, so each gets its own line on the quote. You can start with the oldest pair and plan the rest later.Does a heat pump cost more than an AC and furnace?
It depends on the zone and the equipment. We price a heat pump and a furnace with AC on the same quote, so you see the difference for your home.What if my furnace is red-tagged?
A red-tagged furnace stays off until it is replaced or the fault is fixed. We quote the new furnace, and the AC with it if the pair is due.Book a zone replacement quote
