AC Replacement in Las Vegas: When the Old System Is Done

Replacements we've done in the valley

Real, completed jobs from our job records, listed by job type, ZIP and month:

• Two split systems replaced, ZIP 89143, September 2026.
• Water-source heat pump replacement, ZIP 89109, August 2026.
• Packaged heat pump system replacement, ZIP 89139, August 2026.
• Gas/electric packaged system replacement, ZIP 89074, August 2026.
• Gas/electric split system replacement, ZIP 89129, July 2026.
• Heat pump system replacement with a crane lift, ZIP 89030, July 2026.
• Gas/electric packaged system replacement with duct replacement and repair, ZIP 89107, July 2026.
• Fan coil unit replacement, ZIP 89118, June 2026.
• Two gas/electric split systems replaced, ZIP 89178, June 2026.
• Heat pump split system with a new gas furnace, ZIP 89129, March 2026.
• Gas/electric split system replacement with a secondary drain float switch, ZIP 89084, February 2026.

Nearly half of the system replacements in our records over the past year were gas/electric split systems: an outdoor air conditioner paired with an indoor gas furnace. The rest were heat pumps, packaged units, and air-conditioning-only splits.

What goes in besides the equipment

A replacement is more than setting a new box on the old pad. Our job records show the same supporting work showing up on job after job, because the old parts around the equipment are usually as old as the system itself.

• Electrical disconnect. A new service disconnect at the outdoor unit, so the technician can shut off power at the equipment.
• Condensate drain. A new drain trap or a re-piped drain line, so water from the indoor coil leaves the house the way it should.
• Gas line sediment trap. On gas furnaces, a drip leg that catches debris before it reaches the gas valve.
• Flue pipe. When the old vent pipe doesn't fit or isn't sound, the flue is replaced with the furnace.
• Secondary drain pan and float switch. For equipment in an attic or above a ceiling, a backup pan and a switch that stops cooling if water backs up.
• Line set insulation. Fresh insulation on the refrigerant lines where the old wrap has cracked in the sun.

Replacing the type of system the house has

Most valley houses have a split system: a condenser in the side yard and a furnace or air handler in a closet, garage or attic. Some have a packaged unit, with heating and cooling in one cabinet on the roof or on a ground pad. Others run a heat pump that both heats and cools. High-rise condos often use water-source heat pumps tied to the building's water loop.

We start with what you have and why it failed. Sometimes the best answer is the same type of system, matched and sized correctly. Sometimes the house has changed: an addition, a converted garage, or a second floor that never cooled well. That's when we talk about sizing, ducts, or a different system type. See HVAC permits in Las Vegas for who issues the permit for a replacement.

AC replacement FAQs

Does a higher SEER2 rating save money in Las Vegas?

It can, because systems here run long hours in summer. The real savings depend on your usage and on whether the ductwork delivers the air. Have the ducts checked before choosing a higher efficiency tier.

What is the minimum efficiency for a new AC in Nevada?

Nevada falls in DOE's Southwest region, which adds an EER2 (peak-heat) requirement to the SEER2 minimum for split-system air conditioners.

Should I repair or replace my air conditioner?

Look at the system's age, how often it has broken down, and what the current repair involves. A minor part on a sound system is usually worth repairing. An older system with repeated failures, or a major part like the compressor failing, is often the time to compare replacement. Las Vegas summers are hard on equipment. See our repair or replace guide. Book online or call (702) 738-6976 to schedule.

Can you replace a water-source heat pump in a Las Vegas condo?

Yes. We replaced a water-source heat pump in ZIP 89109 in August 2026. These units usually sit in a closet inside the condo and connect to the building's shared water loop instead of an outdoor condenser. Building rules can set access and timing, so we plan the swap around them.

When does an AC replacement need a crane?

A crane comes in when equipment sits on a roof or can't be carried safely to its spot, such as a packaged unit on a second-story roof. Our records show crane lifts on replacements in ZIPs 89030, 89015 and 89129. We arrange the lift as part of the job, and you'll know about it in advance.

What happens to my old air conditioner after it's replaced?

We haul it away. Before the old equipment leaves, the refrigerant is recovered with a recovery machine, because EPA rules under Section 608 of the Clean Air Act require recovery before an air conditioner is disposed of. Venting it into the air is illegal. Metal and parts then go for recycling.
