Replacing the heating and cooling system is usually the largest check a homeowner writes outside the mortgage. We treat it that way. You will see options before anyone starts tearing out equipment (how we recommend repair or replacement). For AC-only replacement language, also see AC replacement Las Vegas.
Only the AC side is done? See AC replacement in Las Vegas.

When replacement is on the table
We recommend replacement from the equipment, not a sales calendar. Age alone is not the quote.
A capacitor, contactor, fan motor, or control board is a repair. A compressor, a leaking coil, or a cracked heat exchanger on equipment at the end of its useful life is a replacement conversation.
Common reasons a whole-system talk makes sense:
- Equipment past useful life that keeps failing
- Refrigerant that is no longer practical to recharge
- A major repair that costs more than the life left in the system
- A system that has been consistently bothersome, season after season

How we size and install
Sizing starts with the house: square footage is not the calculation. We account for the attic, the glass, the direction the walls face, and whether one system or two is doing the work.
Gas heat plus air conditioning is still the common valley setup. A heat pump can do both jobs where the house and the electric service can support it — see heat pumps. On a straight changeout, the old equipment comes out and the line set, pad, disconnect, drain, matched indoor/outdoor equipment, thermostat, startup, and walkthrough are done cleanly.
Load calculation to ACCA standards — not a rule-of-thumb tonnage guess. Matched indoor and outdoor equipment.
Local rules require a permit and an inspection for a full system replacement. Here is how HVAC permits work in Las Vegas.
Comfort Club credit (if you enroll)
If you are on Comfort Club Gold, ask about the qualifying replacement credit when a changeout is the right path. Other Comfort Club levels and benefits are confirmed when you enroll — see Comfort Club.
System Replacement Questions
How much does it cost to replace an HVAC system in Las Vegas?
It depends on the home, so we do not quote a number before we see it. The main factors are the size the house actually needs (based on a load calculation, not the old unit's label), whether it is a heat pump or a gas furnace with an AC, the efficiency level you choose, the condition of the ductwork, and whether the equipment sits in the attic, a closet, or on the roof. After a visit we give you a quote for your house.
Do I need to replace both the indoor and outdoor units?
Usually yes. Matched indoor and outdoor equipment is designed to work together, and mixing a new outdoor unit with an old coil can cost you efficiency and reliability. We will tell you plainly if one part is still in good shape.
Is repair or replacement the better choice?
Age, repair history, refrigerant type (see what the R-410A to R-454B change means), and how well the system keeps up in summer all matter. We walk you through the repair option and the replacement option so you can decide. Our guide on repair or replace for an older AC covers the main signs.
Does Comfort Club help with a replacement?
If you are on Comfort Club Gold, ask about the qualifying replacement credit when a changeout is the right path.
