Yes. In Las Vegas heat, a broken AC isn't something that can wait until next week. We prioritize no-cool and no-heat calls and offer same-day appointments whenever possible.

Yes, Mr. Gates Heating & Cooling is fully licensed and insured to perform HVAC repair, installation, and maintenance work in Nevada.

A technician will call ahead, diagnose the issue, and walk you through the problem and your options in plain language before any work begins — no surprise charges.

This is one of the most common calls we get in the summer, and it usually points to low refrigerant, a failing capacitor, a dirty condenser coil, or a duct issue. A diagnostic visit will pinpoint the exact cause.

We recommend a tune-up twice a year — once before summer and once before winter. In our climate, the AC does most of the work, so a spring check-up matters most.

Yes. Our seasonal maintenance plan includes two tune-ups a year, priority scheduling, and a discount on repairs — ask your technician or contact us for current pricing.

We repair and maintain all major residential brands, regardless of who installed the system originally.

A common rule of thumb: if your system is over 12–15 years old and the repair cost is more than a third of a new unit's price, replacement is usually the better value. We'll always lay out both options honestly.

Most single-system residential installs are completed in a single day, so you're rarely without cooling overnight.

Older systems lose efficiency over time, so upgrading to a higher-SEER unit typically does reduce summer cooling costs, especially on a system running daily in our heat.

In most cases, yes. We handle the permitting process for you as part of every installation.

We charge a flat diagnostic fee, which is applied toward the cost of the repair if you move forward with us. Call for current pricing.

Yes, we offer financing options for new system installations so an unexpected replacement doesn't have to be paid all at once. Ask your technician about current plans.

Yes. Repairs are backed by our workmanship warranty, and new installations include both manufacturer and labor warranties, details of which we'll go over before work begins.

Final pricing depends on what a technician finds on site — the exact part needed, system age, and access. We always confirm the final number with you before any work starts.
