Repair or replace: how to decide
Nobody replaces an air conditioner for fun, so the first question is whether yours can reasonably be kept going. Age alone does not settle it. In Las Vegas, where equipment logs far more run hours each year than it would in a milder climate, central air conditioners often last 10 to 15 years. These point toward replacement:
- The compressor or the indoor coil has failed on a system more than ten years old
- It runs on R-22 refrigerant, which is no longer produced in the United States, so leak repairs are hard to justify
- Repairs have become a yearly event
- Summer electric bills keep climbing with no change in how you use the house
- Some rooms never get comfortable however long the system runs
A single failed capacitor, contactor or fan motor on an otherwise sound unit is a repair, not a reason to replace. If that is your situation, start with AC repair.
Sizing starts with a load calculation
Air conditioners are sized in tons, and one ton is 12,000 BTU of cooling per hour. Choosing by square footage alone, or copying whatever sits on the pad now, is how homes end up with the wrong equipment. A load calculation, known in the trade as a Manual J, works out how much heat each room gains on a peak summer afternoon from:
- Insulation in the attic and walls
- Window area, glass type and the direction the windows face
- Ceiling height and how much outside air leaks in
- Where the ducts run, which in many valley homes is a very hot attic
- How many people live there and how the rooms are used
An oversized system cools the area near the thermostat fast, shuts off, and starts again minutes later. That short cycling wears parts and leaves distant rooms warm. An undersized one runs without rest and still loses ground at 110°F. We look at the ductwork too, because a correctly sized unit connected to undersized or leaking ducts cannot deliver its rated capacity.
System types for Las Vegas homes
Most houses here use one of four setups:
- Split central AC with a furnace. An outdoor condensing unit paired with an indoor coil and a gas or electric furnace that supplies the blower. Our central air conditioning page compares single-stage, two-stage and variable-speed models.
- Heat pump. It looks like an air conditioner and cools the same way, then reverses to heat the house in winter. Mild desert winters suit heat pumps well.
- Packaged unit. Everything sits in one cabinet on the roof or beside the house, connected straight to the ducts. You see these on many older valley homes.
- Ductless mini split. One outdoor unit feeds one or more indoor units on the wall or ceiling. Ductless systems are a good answer for additions, converted garages and casitas.
Efficiency is rated in SEER2. A higher number means less electricity for the same cooling, which counts for more when the system runs for months on end. We can also check which utility rebates are currently available for the equipment you are considering.
What installation day involves
A like-for-like replacement typically takes a day. Changes to ducts, wiring or the location of the equipment add time. The work goes in this order:
- Recover the old refrigerant and remove the old equipment.
- Set the new outdoor unit level on its pad and install the indoor coil or air handler.
- Connect the refrigerant lines, brazing with nitrogen flowing through the tubing to keep the inside of the pipe clean.
- Pressure-test the lines, then pull a deep vacuum to remove air and moisture.
- Wire the unit, connect the condensate drain and its safety switch, and set up the thermostat.
- Start the system, set the refrigerant charge, and measure airflow and temperature drop.
Steps four and six take patience, and they decide how the system performs for the rest of its life. Moisture left in the lines and an incorrect charge are common causes of early compressor trouble.
Getting a replacement quote
Call 702-497-0888 and we will arrange a visit to measure the house, look over the existing equipment, ducts and electrical panel, and ask how the home feels now: which rooms run hot, what the bills look like, what you would change. You get options with the reasoning behind each one, so you can compare them on more than the label. Our licensed technicians install throughout Las Vegas and nearby Clark County communities. Financing is available, subject to approved credit.
Frequently asked questions

What size air conditioner does my house need?
That comes from a load calculation, not from square footage alone. Two houses of the same size can need different capacities because of insulation, window area, orientation and duct location. Residential units range from about one and a half to five tons, and larger homes often use two systems. We measure and calculate before recommending a size.
How long does a new air conditioner last in Las Vegas?
Typically 10 to 15 years, sometimes longer with consistent care. That is shorter than the figures quoted for milder parts of the country, because equipment here runs many more hours each year in extreme heat and dust. Yearly maintenance, clean filters and a correct installation have the biggest effect on lifespan.
How long does an AC replacement take?
Most straightforward replacements are finished in one day. Jobs that include new ductwork, relocating equipment, electrical upgrades or a change from one system type to another can take two days or more. We tell you the expected timeline when we go over the options, so you can plan for the hours without cooling.
Should I replace the furnace or air handler at the same time?
Usually yes, if the indoor unit is about the same age. Its blower moves all the air for cooling, and an old blower can hold back a new outdoor unit. The indoor coil almost always has to be changed regardless, since new systems use different refrigerants from older ones. A fairly recent, compatible furnace can often stay.
Is a higher SEER2 rating worth it here?
Often it is, because a long cooling season gives efficient equipment more running hours to earn back its extra cost than it would get in a cooler climate. How far up the scale to go depends on your electric use, how long you plan to stay in the home and your budget. We can set the options side by side for you.
