Should I replace the furnace and AC at the same time?

If both are near the end of their service life, yes. The indoor unit typically houses the blower and coil for the cooling system, so replacing them together avoids mismatched equipment and a second round of labor later.

What efficiency furnace makes sense in Las Vegas?

Because the heating season is short, the operating cost difference between efficiency tiers is smaller here than in colder regions. We will walk through the actual tradeoff for your home rather than assuming the highest tier is right.

Can you install a furnace in my attic?

Yes, and most Las Vegas furnace installations are attic or closet installs. We assess access, platform condition, drainage and clearances during the estimate.

Will I need new ductwork?

Not necessarily. We evaluate duct condition and capacity before installation, and if the ducts are leaking or undersized we will tell you what that means for the new system's performance.

Do you handle permits and code requirements?

Yes. Venting, combustion air, gas and electrical work are all done to code as part of the installation.

Furnace Installation and Replacement in Las Vegas, NV

Furnace replacement in Las Vegas usually comes up for one of two reasons. Either the existing furnace has failed in a way that is not worth repairing, or the air conditioner is being replaced and it makes sense to do the whole system at once.

Rocket Air Conditioning installs and replaces residential furnaces across the valley, including gas furnaces and electric air handlers, with the venting, gas and electrical work done properly.

Furnace Installation and Replacement in Las Vegas, NV by Rocket Air Conditioning

Reasons to replace rather than repair

A failed or cracked heat exchanger

This is a combustion safety issue and it is not a repair. When we find one, replacement is the only correct answer.

The furnace is old and parts are getting scarce

Once control boards and safety components are hard to source, every future breakdown means a longer outage.

You are replacing the air conditioner anyway

The furnace usually houses the blower and coil. Doing both at once means matched equipment, one installation and a cleaner result.

Repeated repairs in a short heating season

Our heating season is only a few months. Multiple failures inside it is a strong signal.

The system has never heated the house evenly

That is usually sizing or duct related, and a replacement is the right time to correct it.

Furnace, heat pump or full system replacement

If you already heat with gas and want to keep it, a new furnace is straightforward. Efficiency levels vary, and in a climate with a short heating season the payback on the highest efficiency equipment is smaller than it would be in a cold climate. We will be honest about that instead of upselling.

If you are replacing both heating and cooling, it is worth at least discussing a heat pump, because our winters are mild enough for one to work well and it consolidates both jobs into one system.

Whatever you choose, the sizing and the install quality will matter more to how the system performs than the brand on the cabinet.

Problems we solve most often

Failed furnace that is not worth repairing

Heat exchanger failures and obsolete parts are the two most common reasons a replacement is the honest recommendation.

Combining heating and cooling replacement

Replacing both at once gives you matched equipment, one installation and better overall performance.

Uneven heating throughout the home

Sizing and duct issues are best corrected during the replacement, not worked around afterward.

Furnace work in Las Vegas homes

Most furnaces here live in an attic or a closet, and attic installations bring their own realities around access, platform condition, drainage and working space. We plan for that during the estimate rather than discovering it on install day.

We install furnaces for homeowners across Las Vegas, Henderson, Summerlin and North Las Vegas.

Frequently asked questions

Straight answers to what homeowners ask us most about this service.

It depends on the scope. Attic and closet access, venting changes, and gas or electrical modifications all affect how long the work takes, so the timeline is set once the installation has been evaluated rather than assumed in advance.
