HVAC reviews in Irvine, California

Ron is very patient and helpful on all the questions I have. The reception desk ladies are very nice and helpful as well. The installation crew is very professional and easy to communicate. McMaster follows all the city codes and schedules all the necessary inspections. Their price is also very competitive as well. Highly recommend.

The Technician for annual service was timely and efficient! We are exceedingly happy with our a/c and furnace from McMaster! They are the absolute best in customer service and my allergies have greatly improved with this highly efficient system! Highly highly recommend !!!

McMaster Heating and Air has been a pleasure to work with over the past 10+ years. They installed the central heating and air system expertly, and have maintained it very well. Hope to continue to do business with them for years to come!

Extremely professional organization. From the first service call to verify that my existing system was not worth repairing...to the sales manager (Christian) who walked me through the options and answered my late night email questions...all the way thru the crew who meticulously removed my old equipment and had the new system up and running in less than 2 days (complete new A/C, furnace and ducts), everyone at McMaster (including the owner Ron who stopped by numerous times to ensure everything was going to my satisfaction) was top notch. If you need service or an entire new system, don't hesitate to call McMaster. Fair prices and expert knowledge. Highly recommended A+++

McMaster Air and Heat installed my new air and heating system with the best crew. In my research, it comes down to the installation company. Each member treated my home as their own home. I asked lots of questions and they were each super nice to answer and explain the system and process.

If you are looking into a new HVAC system, call them for a very reasonable quote and the best installation. They left my home as clean as they found it. Give them a call and you will not be disappointed.

We highly recommend McMaster! Excellent installation of a new Furnace and Air Conditioner. The technicians did a fantastic job. They were polite and professional. The owner, Ron McMaster, was very accommodating with the selections he offered us and good value with the pricing.

My wife and I are so impressed with the performance of our new AC system. With a variable speed fan for the inside and a multi speed compressor unit outside it is extremely quiet and you can’t even tell that it’s running. We have a two-story house and now the temperature between the downstairs and the upstairs is 2° where before it was 8° different. The complete installation only took less than six hours and that’s replacing the furnace in the attic also. I’ve had a couple of my neighbors stop by to check out the installation and how quiet the unit is and now they’ve made appointments and are going to use McMaster for their installation. I am impressed with the workmanship of the installation and I can attest to that because I work in the maintenance field also.

We talked to five different companies regarding replacing our 3-ton 23-year-old Carrier HVAC furnace+AC system. Ron was the most impressive of the bunch, he knows his stuff and he was the only one that sat down with us to lay our our options and to answer all our questions. His estimate wasn't the lowest, but we were confident that we'd be getting a quality system expertly installed. Everyone on his team was professional and helpful during the installation and afterwards, and the new Carrier system is working great.

There's a good reason this company has been awarded Carrier's Presidents Award each year for the last 10 years, they are very good at what they do. Ron McMaster was straightforward, knowledgeable and his experience shows. He made suggestions to do things right, explained the base system and the features and benefits to upgrade and improve the system. He gave me a quote for base HVAC system and options and costs to upgrade as to my needs. He supplied us with all the information needed to make an informed decision, he made it making a choice easy.
Alexis in the office, was outstanding in coordination of removing old ducts, installation of units, inspection and city permit and inspection, great communication with phone calls and email updates.
The techs were fast, clean efficient and good at their job.
Great team representing a quality Carrier product, these folks are really good at what they do.

McMaster has given us exceptional service. They diagnosed a problem, ordered parts and returned to install them in record time! I will certainly use them again for our HVAC needs. Highly recommend!

Ron Mcmaster gave great advice and fair pricing on heating units I should consider. His installation team arrived on time and worked diligently to insulate the heater cabinet and install the heater.

MC Master Air was absolutely the best price and quality and professionalism we have experienced in the venture of home remodeling. They were very helpful, easy to deal with, and overall very knowledgeable in their field of expertise. We felt other companies paled in comparison to McMaster. I highly recommend this company who got done EVERYTHING they told us would happen with no gimmicks.

We love McMaster. Our service technician is more than just a technician, he is patient, professional, friendly, and a good listener even with all of my dumb questions. My dumb questions is where his patience matters which is why I'm glad he has a sense of humor also. Because of McMaster, our heating and AC system remains in great shape, even after 18 years. It's a good feeling to know that there are businesses like McMaster that can be trusted.

My service experience with McMaster has been positive and professional, and so good that I hired them for a second job at another property without hesitation!

I became acquainted with McMaster while researching a contractor to install a Carrier variable-speed heat pump for our home. I recall a review on their site that was roughly “these are the guys to hire, don’t bother with others.” Well said. These are the guys to hire for professional installation of a Carrier system - done right. Not only do they know the Carrier product line, they are competitive on price and their customer service is what you would expect from a first-rate contractor. Each McMaster person works like they were doing the job for themselves - down to the smallest detail. This means that there is pride of workmanship and you are treated the way you want to be treated. Their excellent service is company wide; from the owner it extends to each crew member and the office staff who coordinate and schedule.

Recently I needed to consider replacement or overdue maintenance of a 50+ year old HVAC at a condo property. I did not hesitate to call McMaster. Even though this work was a different scope, their previous work was such a positive experience that I didn’t want to consider any other contractors. Their advice was again honest and valuable. The energy efficiency of a new heat pump system was clearly the most compelling reason for replacement. An appropriate and reasonable unit was suggested, the price was within budget, and they were able to meet my remodel schedule. Communication leading up to installation day with McMaster was again first-rate. The same installation crew delivered and installed a fantastic system in just one day!

BTW: the Carrier heat pumps just work and are worth the money, especially a variable-speed setup. Just get it installed by McMaster! Again, these are the guys to hire.

Overall very happy with McMaster Heating and Air Conditioning. One of the reasons I chose them was they are a family owned/run business and they specialize in Carrier products. With that I feel that I have gotten the personal responsiveness of a family run business. The owner, Ron, came out to my house and gave a very detailed explanation of what he recommended and why. The installation team did a great job overall too. There were a few tweaks that had to be done and they have taken care of them with no problems. So far everyone I have interacted with has been great. I had a minor issue and one of their technicians Anthony came out on a holiday and squeezed me in so I wouldn't have to wait the full weekend. Would definitely recommend especially if you are planning to install Carrier products.

I had a great experience with Ron and his crew. Ron personally showed up and gave me the quote on day1. He seemed very knowledgeable and detail oriented. I got a quote from 4 other companies. Even though Ron's price was not the most competitive I still decided to go with him since they were the only one who also inspected my ducts and told me that I have asbestos. Ron sent a professional crew to take out all the asbestos. Then his team came over with brand new AC and Furnace and installed them in a day. Overall, my experience was very positive and I felt that I'm getting a value for the price I'm paying. If you have questions in your mind, I highly recommend weighing the options ( 1 stage/ 2 stage, heat pump or not? , etc. ) with Ron personally. He's not in the business of just selling a product and leaving you hanging. He gives you his best advice right away. I have recommended Ron to couple of my friends and will continue to do so.

I highly recommend McMaster Heating and Air Conditioning. Ron provided reasonable options for me based on the age of my home (100 years) and space for the equipment. He was very responsive and clearly explained each step from permitting to installation, inspection and certification. All went smoothly and he and his team were professional and conscientious for both the installation and first inspection. I would rate them higher if I could.

McMaster did a complete replacement of our HVAC system. They are an authorized Carrier provider and I wanted Carrier equipment. Their price was great (I got 3 bids) and the service was 5-star. Of the 3 companies I considered McMaster was the only one to discuss options and rebate opportunities. Their price was competitive as well. But my biggest 5-star experience was the installation. The furnace was in the attic and the access was limited. The McMaster crew came in and replaced the whole system in a day. They left the jobsite clean and the new system works great - passed the HERS test and city inspection with flying colors. I can't recommend them highly enough and I'm a persnickety person - so I've been told.

We are very pleased with the service of McMaster Air. This past Tuesday, their technician was on time and serviced both our heating and air conditioning units and replaced our two UV tubes. He was fast, efficient, polite and so helpful, too! We bought our units from McMaster Heating & Air Conditioning and only use them to do our annual service.

The entire team at McMaster did a great job for us. Everybody was helpful, quick to respond to requests, and provided a very high level of customer service.

The day of the installation was flawless. Anthony showed up early and got everything set up and installed in less time than we thought it would take. He is really nice and very helpful when questions came up.

McMaster went FAR above our expectations. We will definitely use them for future needs and highly recommend them to others.

McMaster's is the best. Honest and fair. This is the second system they have done for me. I used them in my old house and would not have trusted any one else for the job. Outstanding work and great customer service.
