Frequently Asked Questions

Yes! We proudly offer financing options for homeowners and businesses across the Las Vegas Valley. Whether you’re replacing an old system or upgrading to a more efficient model, we’ll help make it affordable with flexible monthly payments. Ask us for details.

We primarily install Goodman, Amana, AC Pro, and Trane systems — known for durability and performance in the Las Vegas heat. However, we can install any brand you prefer. Just let us know your preference, and we’ll handle the rest.

Yes! We offer:

  • Quarterly and biannual maintenance plans for commercial properties

  • Seasonal tune-ups for residential homes (recommended before summer and winter)

Preventive care keeps your system running longer and more efficiently, especially in extreme Las Vegas weather.

Yes, we provide 100% free estimates on new HVAC system installations. We’ll come to you anywhere in the Las Vegas Valley, inspect your property, and give you an honest quote with no pressure.

Yes, our standard service call is $80, but we waive that fee if you choose us for the repair or installation. You’ll never pay twice.

There are several smart reasons:

  • Frequent repairs = higher long-term costs

  • Older units may have discontinued parts

  • Cracks in the heat exchanger can cause carbon monoxide leaks

  • Outdated units are less energy-efficient

If you’re in the Las Vegas Valley, we’ll inspect your system and give you honest advice.

Yes. Modern HVAC systems are designed with higher SEER ratings (Seasonal Energy Efficiency Ratio), meaning they use less electricity to keep your home cool. This can lead to monthly savings, especially during Vegas summers.

Absolutely. Seasonal maintenance:

  • Catches small issues before they become costly

  • Extends the life of your unit

  • Improves efficiency year-round

We recommend tune-ups before summer and winter — especially important in the Las Vegas heat and desert cold.

We recommend a standard box filter with a MERV rating between 5 and 8. This provides a good balance between airflow and filtration for most Las Vegas homes.

Each system requires a specific filter size. Check the side of your current filter — the correct size is typically stamped or printed there.

We offer a 10-year manufacturer parts warranty and a 1-year labor warranty on all new system installations. That’s peace of mind for every Las Vegas homeowner.

The most common causes include:

  • Dirty or clogged air filters

  • Low refrigerant (leaks)

  • Restricted airflow or dirty coils
    If you’re noticing ice buildup, schedule a service call before it leads to bigger issues.

Uneven temperatures are often caused by:

  • Pinched or broken ducts

  • Blocked or undersized vents

  • Poor duct design
    We’ll inspect your ductwork and airflow to diagnose the issue.

No. HVAC systems must be properly sized based on your home’s square footage and heat load. Installing a unit that’s too large can lead to:

  • Poor efficiency

  • Higher utility bills

  • Shortened equipment life
    We’ll calculate the correct tonnage for your Las Vegas home.

On average, HVAC systems last 12–20 years, but regular maintenance and filter changes can extend that lifespan — especially in high-demand climates like Las Vegas.

No. R-22 (Freon) was discontinued in the U.S. as of 2020 due to environmental concerns. It’s no longer produced or imported.

Most modern systems use R-410A, a more eco-friendly option. However, the industry is now shifting to newer, lower-impact refrigerants like R-32 and R-454B. If your unit uses R-22, it may be time to consider an upgrade.

Common culprits include low refrigerant, dirty filters or coils, faulty capacitors, or thermostat issues. For example, The Spruce notes low refrigerant and dirty coils as frequent causes.

Dirty filters, causing coil freeze, clogged condensate lines, or cracked drain pans are typical reasons. Better Homes & Gardens identifies seven main causes of filter issues, freezing coils, condensate clogs, and more.

Experts recommend at least once a year, ideally before summer, to ensure efficiency and prevent breakdowns.

If it’s over 10–15 years old, constantly needs repairs, or your energy bills have spiked, it’s time for a replacement.

Signs include warm or weak airflow, frequent cycling, odd noises or smells, leaks, or high humidity indoors.

You can:

  • Change filters

  • Clean coils and vents

  • Reset blown fuses or breakers
    But refrigerant leaks, frozen coils, or electrical issues require professional help.

Essential questions include:

  • Are you licensed and insured?

  • What brands do you recommend?

  • Do you finance, offer warranties, or maintenance plans?
