TESTIMONIALS
Hear From Our Happy Clients
Amy OstbyTrustindex verifies that the original source of the review is Google. Working with Mr. Gates heating and cooling was a great experience. Dalton was so professional and so patient as we worked through our options. He found discounts and promotions that would enable us to afford a new unit. I really appreciate his professionalism and dedication to making sure our experience went as smoothly as possible. William WattsTrustindex verifies that the original source of the review is Google. had an issue with my AC system and connected Mr. Gates via Thumbtack. I received a quick response from Dalton. His team schedule an appointment to assess the AC system. The technician found a pinhole leak in the outside coil caused by a severed wire spark. They checked the complete system and provided me a couple quotes with different options to repair the system. All this was done quickly and they left and let me review the quotes for a day and decide which option worked best for me. I felt no pressure during the process and called Dalton to discuss each of the options with him. I recommend this company to all my southern Nevada neighbors. T MillsTrustindex verifies that the original source of the review is Google. I received a referral yesterday to call Gates Air-Conditioning and Heating. He was available the same day but I had to schedule him in for today. Mr. Gates took his time to explain what was going on with my air conditioning unit. He was very professional, answered all my questions and was able to get me back up and running the same day thank you, Mr. Gates for your excellent service. Adam McGrathTrustindex verifies that the original source of the review is Google. I’ve had the pleasure of working with Mr. Gates Heating and Cooling twice now, and both experiences have been outstanding. Dalton is the definition of professionalism—honest, reliable, and genuinely customer-focused. While other companies tried to upsell me on unnecessary units and inflated costs, Dalton took the time to explain everything clearly and gave me straightforward, honest advice. His communication is excellent, and it’s obvious that he truly cares about looking after his customers. I would highly recommend Mr. Gates Heating and Cooling to anyone looking for trustworthy, top-notch service. Stephen ZeerTrustindex verifies that the original source of the review is Google. Very dependable with immediate response which you need when it’s summer in Vegas! Every detail was fully explained and were always in contact from beginning to end of project. Felt comfortable with Dalton and his techs and so appreciated their honesty. Would definitely hire again! Caroln KilgoreTrustindex verifies that the original source of the review is Google. Prompt, professional, and affordable! Cris did a fantastic job! I would highly recommend!!! Gavin YTrustindex verifies that the original source of the review is Google. Following an extremely unpleasant experience with another local AC/Heating company, I called Mr Gates to schedule an annual maintenance on my system. From the initial phone conversation through the actual service visit, I received professional, knowledgeable, and cordial treatment. I couldn't be happier! Mr Gates has my business going forward! Thank you Cris! Ragini BhaktaTrustindex verifies that the original source of the review is Google. Mr. Gates was the 2nd company we asked to evaluate our HVAC and he spent over 2 hours assessing the system's response to a change in the thermostat and measuring the temperature of the air coming into the house. He explained what defines an efficient system and trouble shot the issue. Unlike other companies, he tried to repair our existing system by adding coolant, waiting for it to circulate, and re-measuring the temperature is the air in the house. Since Mr. Gates evaluated our HVAC, our house is so much cooler! He was neat, honest, and trustworthy. When we need a new system in the future, we will definitely use this company! You will be so glad to give them a call and can trust his experience and expertise. 💪🏾👌🏽🙏🏽 jennifer snyderTrustindex verifies that the original source of the review is Google. If I could give 10 stars I would! Dalton and Cris and their entire install team were awesome. I needed to have both my AC units replaced and after getting several estimates I went with Mr. Gates Heating and Cooling. They gave me an honest and fair bid. During the whole process Dalton was in constant communication with me answering all my questions and concerns. It's so hard to find a trustworthy reputable company anymore but I found one with Dalton. I highly recommend them for all you AC needs. Iris S.Trustindex verifies that the original source of the review is Google. We have had hot air blowing from one our a/c units for the last 3 weeks as we went through multiple people to try and fix it. The last a/c company told us it was the compressor and they recommended to replace the unit instead. We were not ready to do that so we reached out to Dalton. He was able to get us scheduled the same day and within 2 hours he was at our front door. We are so thankful that he was able to save us thousands of dollars. The issue was not the compressor, it was burnt out wirings. If not for Dalton’s expertise, we would have spent a lot to replace the unit. He also gave advice on how to maintain the unit to prolong its life. Thank you so much, Dalton!! We have already provided your contact information to family, friends, and colleagues.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

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?
What exactly is included in the quote?
These align with Trane’s and Hanna Heating’s top contractor queries.
