Reviews

Both Eric Medina and Chris Barrett were super professional, friendly, and clearly knew exactly what they were doing. They explained the issue, fixed it quickly, and even cleaned up after themselves — which I really appreciated. I’ll definitely be calling them again for any future plumbing needs. Highly recommend!

Eduardo Martinez was very personal and very helpful great service

I received exceptional service from Tim and Eduardo. They came out on time, diagnosed my air condition challenge and explained how they were going to resolve my problem. They were very concise and creative in resolving my challenge. I would 100% recommend them to a friend or family member. Great service.

These guys are awesome. From the install of new system last year to the check ups since. I would recommend them for whatever you need done. Fair price, but service above any others I’ve used. Very friendly staff and things explained in ways I understood. Enoch has been out twice for check ups and he is a great guy. So glad I chose to go with CoolMasters.

I have been using Cool Master for more than six years and have been very happy with their work and technicians. Customer service at Cool Master is very accommodating, courteous and professional. Their technicians are very thorough, knowledgeable, friendly and professional. The technician Humberto Vargas was our recent technician and he was on time to our home! He’s was very knowledgeable and patient, he was exceptional! He called me at work after the my AC check up and gave me the report and recommendation for the unit. My husband described Humberto Vargas as awesome! I am completely satisfied with my service!! 😊

I got very good customer service. Great experience.

Very professional company. I highly recommend their services.

Humberto Vargas very professional and went above and beyond to get our unit fixed, his inspection report was honest and on point. Pricing was absolutely more than fair, I'm going to call them again in the future, can highly recommend them to anyone 👍🏽

Eduardo provided Expert recommendation on the filter replacement. He included surge protectors installation. Service was done in less time expected and clean up after the installation. GREAT CUSTOMER SERVICE! Thank you

Dominick did a great job, very thorough.explained how the system worked Tm came by and inspected the work. Good follow up. .i am looking for a recommendation for an air quality monitor.

Thanks for your great service. I highly recommend Eduardo for all your HVAC needs.

Eduardo was fantastic!! He was on time and extremely thorough. He explained everything he did and made sure all my concerns were addressed to my satisfaction. Great service!

Cool Masters Services serviced my heating & cooling unit and reported significant leakage in the 67 year old unit. No other vendor noticed this despite years of service. For this, I'm truly grateful it finally got noticed and properly repaired. I couldn't be more pleased with the finished product. No more leaks and my system is completely refurbished. Thank you, the team who completed this work. Thank you, Humberto for identifying and reporting the leakage! Thank you, Ian and Chris for supporting all the repair work that was needed. Despite challanges, you kept focused and knocked out the work very professionaly. A huge thanks and relief at my end knowing the refurbished work is to spec and upgraded.

Recommend them for service and value
They won’t take advantage of you and will even make suggestions on savings.
Prompt and very courteous

Edwardo was prompt, informative and considerate.... We appreciate his service

Eduardo with Cool Masters is alway professional and very hard working. He stays at the job until you are 100% satisfied. He has been to my home before and I was excited to see that he was my tech this time. He explained my problem and promptly fixed my ac. I will request him in the future.

Chris was very personable and professional, he listened to my concerns and provided me with info on how to keep pipes flowing smoothly. They also did a great job connecting my pipes together in my crawl space. I would highly recommend them and will use their services again.

Apparently, I needed a new HVAC system after shivering in the nine-degree weather at Christmas. Eric came out to do the estimate. He arrived on time (even a couple of minutes early, which says a lot to me). After checking out the system, he explained everything to me and answered all of my questions. The system was installed, and they've checked on it several times. Gabriel and Joey are two of the wonderful young men they have working for them. Everyone has been super polite, friendly, and professional. If you need a new HVAC system, repairs, or maintenance, you won't be sorry if you choose them!

I've had my new HVAC system for a couple of years now. The guys come out twice a year for maintenance. Today, 3/11/25, Eduardo came out. He did an excellent job. He was polite and courteous.

The customer service is very good and the service provider of cool masters are Punctual, Professional, Courteous, polite and kind.. I would highly recommend them for all of your HVAC Service needs

Very professional and excellent job!

Best choice for HVAC systems. I have 4 systems and trust all my services with Cool Masters. Techs are very courteous and never try to up sell you!

My technician Humberto Vargas, was very helpful and very knowledgeable about everything involving my unit. A smooth and efficient service.

I have been using Cool Masters for years. I always receive great feedback and excellent service.

He was very thorough. Very professional as well

Always professional, never pushy with up sales or add-ons. And I've never gotten a bad vibe ever from their techs, I generally feel safe leaving them alone to do their work unsupervised. Can't recommend them enough!

Quick and excellent service

Gas hot water heater replacement. Competitive price and the job was quickly scheduled after the estimate. Upon arrival , the Service Technician suggested we relocate the water heater in our mechanical room to free up space- no additional charge. Good job cleaning up afterwards.

Eduardo is fantastic, he knows my system here and is good with my 2 dogs !

Professional, reliable technicians.
Great customer service.
Used for 10+ years.

Thanks.

Cool Masters came out. I thought they only did plumbing but discovered they also do HVAC as well. Great service and I trust them!

Discovered upstairs AC not working on the first hot day of the spring last Saturday. Called several places who said they could schedule a call next week.

Called Cool Masters around 11 AM, and dispatcher said they could set me up for 2-5 PM that day. Jonathon called and arrived at 3 PM. He found a tripped breaker, and that the most likely problem was the compressor. But when he checked, he found no problem with the compressor itself, but that a seldom used heating component that prevents ice from forming when AC is running in cooler outside temperatures was the problem. He disabled the faulty, but unnecessary part, and immediately problem was solved. He checked the Freon level, found it was down slightly, and topped it. off.

Jonathon is by far the most professional and the sharpest technician I have ever dealt with for any home repair. He noted that the unit was 21 years old, and provided current estimates for replacement when it inevitably dies. His advice for the time being was to "run it 'til the wheels fall off". When that day comes, I will be calling Cool Masters, and asking for Jonathon.

Eduardo was FANTASTIC. He gave all the information that I needed to keep my two systems running in sync along with some tipps that will keep my systems running in good condition. He was very polite and on time.

Cool Masters Inc dod a great job on our plumbing job! The team was very efficient, knowledgeable, and tidy in our home.

Cool Masters consistenly offers great service. Today Eduardo did an excellent job checking over my HVAC system to ensure it was functioning at its best. I appreciated the quality work he did and the time he took to answer my questions and offer advice. I definitely recommend Cool Masters for great service and quality products.

Extremely knowledgeable and explained everything to me in layman terms. Very polite and personable. Very good experience in all ways.

Javier was friendly, competent, and on time to service my HVAC units today! Thanks, Cool Masters!

I worked with Eduardo and he was very professional and timely. He identified the problem and came back for the repair quickly once the part was in. I appreciate his report of his work which included lots of photos.

Cool Masters has always treated us very well. We are so appreciative of each tech’s willingness to share their thoughts and honesty on best steps to care for and repair our heating/cooling systems. Today Eduardo did an excellent job of inspecting our A/C and offering his expertise on what to expect with our current system as well as what we anticipate will be a fairly quickly need to replace that system. We’re grateful to Eduardo and the entire Cool Masters team for their honesty, expedient service, and excellent care for their customers.

Great customer service. They did a great job.

great costumer service from Mike, fast response from the company,We got our heat unit fixed on no time.

Cool Masters was prompt and professional and friendly. Did a great job for me.

Their service was spectacular they handle my problem with efficiency at a low cost and we're very Available for any questions I am happy to use their service again and would definitely refer them to any of my friends or relatives. I have used their service on 3 other prior occasions with no complaints at all. The owner Mario Sandoval will go to extra mile To satisfy your AC And heating needs.

Excellent service, timely and very professional. Not pushy and very reliable.

Raul Flores was extremely professional, kind, and did a great job of explaining what he was doing and why. We purchased a yearly maintenance plan and look forward to dealing with this company again in the fall and for years to come.

They are always on time and keep us posted on their arrival time. I would like to note that yesterday the technician put 2 of our on 65 so that he could test them. We didn't realize this until last night when we were freezing cold. The units ran almost nonstop for 5 hours. I wish he would have let us know he set them that low so that we could have reset the temp.

Raul was excellent. He handled things quickly, explained things well, and worked late to resolve our problem. We are so glad we chose Cool Masters and that they sent Raul.

Raul was very professional and went above and beyond to get our unit fixed; his inspection report was on point, and pricing was absolutely more than fair.
I will use Cool Master again and can only highly recommend them👍🏽

Amazing service! Speaking to Kimberly to get scheduled was a joy, and I’m looking forward for our first humidity consultation 🙂

Very professional and thorough. Did a great job on explaining what he was doing and what maintenance I will need. Chris was also helpful and honest on what parts of my AC unit were worth replacing before needing a whole new one

Amazing, caring company!

Very good service. I appreciate all the knowledge my service technician had. He was very good at explaining any concerns l had.

Very professional and process from estimate to installation was quick and efficient. We are loving our new HVAC system!

Enoch did a super job. He was professional and explained my new thermostat system to me and put me at ease with my 1st WiFi system. Enoch completed the work in a timely manner.

I looked at their reviews, and they were good, so I call them and needed service right a way. They didn't disappoint. Christopher was able to come to our home earlier. He fix the proble with our heat, and he was a very nice man. So everything is great and we now have a company we will use to maintain our a/c s and heaters. Thank you Cool Masters, we are very happy.

Johnathan responded within seconds of my Yelp request. Was overly accommodating and kind! It’s hard to find people who still blow your mind in service and being a true knowledgeable professional of their trade! My new go to!

Christopher was excellent! He took me step by step on what needed to be done and explained all the cost to and gave me a military discount! He is awesome!

I’ve always had fantastic experiences with Cool Masters. Great service with fair pricing. Their techs are professional, knowledgeable, friendly, and they do a great job explaining what’s going on with my hvac systems. Raul was our tech today and he was exceptional!

Extremely professional, very quick, and the best part is they got the repairs covered under warranty and my AC is finally blowing cold air!! Thank you Johnathan!!
