Replacing an HVAC system is one of the biggest comfort and energy decisions a homeowner makes — and one of the easiest to get wrong. A unit that’s too big or too small, ductwork that was never checked, or equipment that isn’t suited to your part of San Diego can cost you for the next 15 years.
Omega Air handles HVAC replacement from the first assessment to the final inspection, as a licensed C-20 residential HVAC contractor in San Diego, so the system that goes in is the right one for your home, not just the one on the truck.
Not every breakdown means a new system. But these usually do:
Not sure which side of the line you’re on?
Our guide to the $5,000 rule for HVAC gives you a simple way to weigh repair cost against system age, and our AI-powered HVAC diagnostics can give you a straight, data-backed answer for your specific system.
If your AC or furnace has died and you need answers fast, start with our emergency HVAC repair team. We’ll diagnose it first and tell you honestly whether it’s worth repairing.
If replacement is the smarter move, we can move quickly on that too — same-day appointments are available, and we won’t push you into a full replacement if a repair makes more sense.
We look at your home, your existing equipment, and your ductwork, then size the new system with a Manual J load calculation instead of a square-footage guess. Sizing is where most bad replacements go wrong.
You get a straightforward quote with the equipment choices side by side, so you can see what you're paying for.
California requires permits for HVAC replacement, and we handle that as part of the job.
Our licensed technicians remove the old equipment, install the new system, and check ductwork, electrical connections, and drainage.
We test the system, confirm it's performing the way it should, and show you how to operate it.
We install and service all major brands, including certified Bryant installation for homeowners who want that brand specifically.
Pricing depends on system type, home size, ductwork condition, and efficiency level.
As a general 2026 range for San Diego, a standard AC and furnace change-out typically runs about 6,000–9,500, a high-efficiency heat pump system about 10,000–16,000, and a ductless mini-split installation about 4,500–12,000 depending on the number of zones.
For a full breakdown of what drives those numbers, see our 2026 HVAC pricing guide for San Diego.

Warranty coverage depends on the equipment installed. We explain exactly what’s covered before you sign.
Most standard replacements take one to two days. A full system with ductwork changes or a multi-zone ductless setup can take longer. We give you a realistic timeline in your estimate.
Size should come from a load calculation based on your home's insulation, windows, layout, and sun exposure, not square footage alone. Oversized and undersized systems both cost you in comfort and energy.
Sometimes, but mismatched equipment can reduce efficiency and may affect warranty coverage. We'll tell you honestly whether a partial replacement makes sense for your system.
Yes. HVAC replacement generally requires a permit in California, and we handle it as part of the job.
Spring and fall tend to be easier on scheduling and pricing, but if your system fails during a heat wave, don't wait. Our emergency HVAC repair team can get you answers the same day.
It depends on the equipment and current programs. Our rebates and financing page tracks what's active right now.
