When the house is heating up fast, you need a shortlist of air conditioning companies, not a search marathon. This page lists HVAC businesses serving the valley with star ratings pulled from public Google reviews. We sort the table by review volume, so companies with the most public feedback rise to the top, and any business that paid for a featured slot is labelled that way. Pick two or three to call, then skim the sections below for quick checks you can do yourself and the questions that separate a repair from a sales pitch.
123 rated ac & heating in the valley meet our bar (4.0 average or better, 10+ reviews, not marked closed; how we pick and order listings). The table shows the 40 with the most reviews. Data refreshed October 2026.
Before you book a visit, confirm the thermostat is set to cool with fresh batteries, replace a clogged filter, and look for a tripped breaker or a pulled disconnect at the outdoor unit. A frozen indoor coil usually means restricted airflow, so turn the system off and let it thaw before calling.
If someone in the home is elderly, very young, medically fragile, or if pets are inside, tell the company when you call. Many prioritize those households during heat waves.
Close blinds on sun-facing windows, run ceiling fans, and avoid the oven. Moving to a cooler room or a friend's home is reasonable on the hottest days.
Capacitors, contactors and fan motors work hardest in triple-digit heat and are common summer failures. Refrigerant leaks cost more because the leak needs locating, and older systems may use refrigerant that is costly to source.
Some homes have package units on the roof or air handlers in hot attics, which slows the work. Crews walking on concrete tile can crack pieces, and a tile roof repair crew may need to follow up.
Desert dust loads filters quickly. Changing them on schedule and keeping indoor dust down with a regular house cleaning service both ease the strain on the blower.
A new system may need a new disconnect or circuit, handled by an electrical contractor or the HVAC company's own licensed staff.
Send the details once. We text you back with rated options for the job.
In Nevada, air conditioning contractors are typically licensed by the Nevada State Contractors Board under the C-21 refrigeration and air conditioning classification. Technicians who handle refrigerant also need federal EPA Section 608 certification. Our steps for confirming a C-21 license walk through the lookup.
A company may recommend a new system. That can be sound advice for an old unit, but ask for the repair price too, in writing, so you can choose.
Scheduling a tune-up before the first long heat stretch lets a technician catch weak capacitors and dirty coils while appointments are easier to get. The valley home maintenance calendar places AC service in that window.
Weigh the system's age, how often it has failed, refrigerant type and how well it keeps up on peak days. A replacement quote should name equipment model numbers, a sizing method and permit handling.
In East Las Vegas and Sunrise Manor, where many homes have been standing for decades, ask whether ductwork has been inspected, since leaky ducts can undercut even a new system.

It varies with demand. During long heat waves many companies run booked schedules, so same-day service is not guaranteed. Calling early in the day, describing the problem clearly, and mentioning vulnerable people in the home all help. Having two or three companies from the table ready saves time if your first choice is full.
It can be, if it includes a real inspection, coil cleaning and priority scheduling in summer. Read what is covered, whether parts discounts apply, and whether the plan renews automatically. Compare that with simply booking a single spring tune-up on your own each year before you decide.
Often yes. Many valley homes have air handlers in attics, and some have rooftop units. Ask the company how they protect tile roofs and whether they will check for cracked tiles afterward. Attic work in summer is usually scheduled early in the day because of heat.
Ask the technician to show you the failed part or the readings that support the recommendation, and request a written repair price alongside the replacement price. A second opinion from another licensed company is reasonable for a major purchase, and an honest contractor will not object to you getting one.
