If you are replacing a system in Las Vegas, this is the fork in the road: a heat pump that both cools and heats, or a traditional split system with a gas furnace for winter. Most articles on this answer for a national audience. The answer here is different, because our climate is different in a way that genuinely changes the math.
Why Las Vegas Changes the Answer
The standard argument against heat pumps is that they lose efficiency when it gets very cold, and in a Minnesota winter that is a serious limitation. Las Vegas does not have a Minnesota winter. Our overnight lows sit in the 30s and 40s through the coldest months, which is comfortably inside the range where a modern heat pump still works efficiently.
Meanwhile the cooling side is doing brutal work for five months a year. That reframes the whole decision. In this valley you are not really choosing a heating system, you are choosing a cooling system that also needs to handle a mild winter.
Heat Pump: Where It Wins
One System, Both Jobs
A heat pump cools in summer and reverses to heat in winter, so you maintain one piece of equipment instead of two. Fewer components means fewer things to fail and one service visit instead of separate heating and cooling calls.
Efficient in Our Winter
Heat pumps move heat rather than burning fuel to create it, which is far more efficient in mild conditions. In Las Vegas winters they spend nearly all their run time in the range where that advantage holds.
No Gas Line Needed
If your home is all-electric or does not have gas run to the furnace location, a heat pump avoids the cost and complication of adding one. That alone can decide it on some properties.
No Combustion Safety Risk
Nothing burns, so there is no heat exchanger to crack and no carbon monoxide risk from the heating side. For some homeowners that is worth more than any efficiency number.
Gas Furnace and AC: Where It Wins
Stronger Heat, Faster
A gas furnace produces genuinely hot air and recovers a cold house quickly. Heat pump air is warm rather than hot, and some people notice and dislike the difference even when the house reaches the same temperature.
Lower Upfront on Replacement
If you already have a working furnace and only the AC has failed, replacing just the condenser and coil is usually cheaper than converting the whole system to a heat pump.
Cheap Natural Gas
Where gas is already at the house, running the furnace on the handful of genuinely cold nights each winter costs very little. The heating side is simply not where your energy money goes in this valley.
Simpler Electrical Requirements
Heat pumps can require an electrical panel upgrade on older homes. A gas furnace paired with a standard AC condenser often works with the service you already have.
Side by Side
| Factor | Heat Pump | Gas Furnace + AC |
|---|---|---|
| Equipment count | One system, both seasons | Two systems to maintain |
| Winter performance here | Efficient in Las Vegas lows | Strong, fast recovery |
| Air temperature at vents | Warm | Hot |
| Gas line required | No | Yes |
| Possible panel upgrade | Sometimes | Rarely |
| Combustion safety risk | None | Heat exchanger and CO to monitor |
| Best fit | All-electric homes, full replacements, long-term owners | Homes with gas and a healthy furnace already in place |
How We Actually Decide On Site
When we quote a replacement, the recommendation comes from the house, not a preference. What we look at:
- Whether gas is already run to the furnace location and in good condition
- The age and condition of the existing furnace, since a healthy one changes the math entirely
- Electrical panel capacity and whether a heat pump would require an upgrade
- Ductwork condition and sizing, because both options depend on it equally
- A proper load calculation for the square footage, insulation and sun exposure, never a guess from the old unit's size
- How long you plan to be in the home, which decides whether efficiency gains have time to pay back
You get the numbers for both paths and we tell you which we would choose and why. If you want the installation detail first, our air conditioning and installation services page covers what the work involves.
Free Estimate on Either Option
We quote both paths on the same visit, with a real load calculation, so you can compare actual numbers for your home. 36-month financing at 0% with 90 days of zero payments.

Will a heat pump actually keep my house warm in a Las Vegas winter?
Yes. Las Vegas winter lows sit in the 30s and 40s, which is well within the range a modern heat pump handles efficiently. The cold-weather limitation people worry about applies to climates that spend extended time near or below freezing. Our winter is not that.
My AC died but my furnace is fine. Do I have to replace both?
No. If the furnace is healthy and reasonably young, replacing just the condenser and evaporator coil is usually the better value. We will tell you honestly if the furnace has enough life left to justify keeping it, rather than pushing a full changeout.
Is financing available on a full system replacement?
Yes. ACE offers 36-month financing at 0% interest with 90 days of zero payments to start on all new installations, plus a 10% discount for military members, veterans and seniors. We cover Las Vegas, Henderson, Summerlin and the surrounding valley.
