We are very happy with McMaster Heating and A/C. The guys showed up on time, with masks, booties and tarps to protect my floor. I really appreciated them respecting and caring enough to be careful and safe. I am extremely particular but couldn't find a thing to complain about even if I tried. They were very professional, polite, work fast, extremely efficient and did a wonderful job with installation. read more

About five years ago I had McMasters replace my furnace in our Irvine Condo, and a few weeks ago we called them to replace our a/c! I am so impressed by this Company that if I could give them 10 stars, I would! They are on time, clean and very professional throughout the whole process of our estimate, installing our units and seeing us through the HERS testing to a successful "pass!" I am thankful to have found such a company! Ron, keep up the outstanding work! I will call you when our a/c gives out in our home in Foothill Ranch! (Hopefully not for years, tho!) read more

No complaints whatsoever. The office staff was professional, had good communication skills, and generally easy to work with. They even were able to schedule a same-day after hours appointment. Our technician, Justin, arrived on time (a bit early, actually), quickly repaired our broken condenser, and saved us from two weeks of roasting in our own house. I would definitely use McMaster again, but hopefully I won't have to do so in the near future (crosses fingers). This was probably one of my best experiences with a contractor. read more

We are a small business in San Clemente & we are so impressed with the service McMaster's provides! They are quick to respond to all of our needs! We highly recommend them for all of your Heating & Air Conditioning needs! read more

I have used McMaster in three different homes now and I would never use anyone else. I just moved and used McMaster to install a new hvac. I also had to have asbestos ducts removed and new ones put in. Ron is honest and reliable. And his crew is fantastic and did a great job. you wouldn't even know they were here after it was all done. there is no point calling anyone else just use them and you will be extremely satisfied, as I am read more

They were very courteous. Always helpful. I would highly recommend their services. They did a very good job of installing our ac and furnace. Started on time and finished it the same day. Whenever I had problem they immediately came and serviced. read more

I want to be sure that the record is clear here........ I am not sure what contractor referred me that has refused to work with me because I still work with AC Cool who referred me at my other home in Irvine, no issues and they just went to my home a month ago to service that AC. They don't work in Laguna Woods due to the strict rules and issues so they referred me to Ron McMaster. Also I was never rude to Mr. McMaster's staff, I explained that until I had city sign off and HERS, I was not going to pay the balance and I NEVER withheld money that was paid by McMaster to the LW Association which was $250. I had already been in their offices and they told me it could be 30-60 days and McMaster was paid within a week of finishing the job which was when the city and HERS inspections passed. I am pleased that he now has adopted some new paperwork to make sure that communication is clear as that was our issue. They did a good job but the communication and constant calls to get money were absolutely embarrassing on his part. He was paid a deposit and the remainder was paid when the city and HERS were complete which is standard, the association was a completely different story and I did not in any way hold Mr. McMaster hostage on that one. I still stand by my original review - good work, terrible communication and bullying when everything doesn't go his way. read more

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. read more

They came to us from a neighborhood recommendation. We replaced both upstairs and downstairs units. Increased duct returns. Added a 2nd return to upstairs unit. They improved the downstairs return build in the wall from original home builders. Crew of 4. Work done in 2 days. WiFi Thermostats. Lots of rebates and easy to get from Carrier and SCE. Very professional 5*****. Have recommend to other neighbors too. Big saving on monthly electrical bills since replacing units. read more

im very impressed by ron (the owner)! I called him 2 days ago and asked for him to come out to install our AC unit and do all the finishing touches for our home (so that we can move in on time) and even with his busy schedule he was able to pull through within 1 day!! They are extremely professional and do their job in a timely manner! Thanks again Ron! read more

I normally do not take the time to write reviews but felt compelled to do so after the professional outcome of my installed HVAC system by McMaster Heating and Air. Just yesterday, the Irvine City (HVAC) inspector complemented the workmanship. And that was similar with the third party HERS testing technician who stated that work that he has seen from McMaster has always been top notch. I initially chose this company because of the great cost savings. It is my recommendation that you do your due diligence when looking for an HVAC company but I highly recommend including an estimate from McMaster Heating and Air. I have been more than satisfied with the outstanding and professional work that they have done for me. read more

From start to finish, McMasters fulfilled every promise. They were prompt, professional, respectful of my home and furnishings, friendly and polite, and delivered a quiet, efficient heating and air conditioning system that far exceeds our expectations. The new unit is exponentially quieter, more efficient, easier to program than the old one, and we are very satisfied with the decision we made. We had several other quotes, but James at M.M. was the only rep who suggested personal, specific solutions to our noise and air flow problems. They redesigned and replaced our ducts, replaced all our vents, and enlarged some of them to give us a wonderful new system. I highly recommend them - they are as good as it gets! read more

We needed to replace our aging furnace and was referred to Ron McMaster by several work colleagues. One particular colleague is the type of guy who does his homework and is the go to guy for all home improvements. As a Factory authorized dealer for Carrier, Ron has great technical insight to the product and install. Our house has had a pex re-pipe and I was a little concerned that the pipe location within the attic space would obstruct the install and be prone to damage. I'm very impressed to say that the install technicians re-routed the pipes and created easy access to the furnace, they must have read my mind:) read more

We needed a new AC to replace our 30 year old system. We got several quotes from local Carrier Installers. They did a great job with the installation. It was quick and the installation crew were pleasant and explained everything. We highly recommend this company. read more

Changed 21 year old HVAC with Carrier Infinity series 2-stage dual zone HVAC. Anthony came to do the measurement and explained very clearly for different options. He was very knowledgeable and patient. The quote he provided was the lowest among 4 bids. It took 2 days to haul way old system, install the new system, replace ducting with R-8 in the attic, add duct to newly added loft. It was challenging to move the new furnace up into the attic since the opening was barely wider but the crew did it without any damage. Anthony was always here for help, he did everything including efficiency report, pulling city permit, meeting with inspectors and applying Carrier rebate and Energy upgrade rebate for us (I got them all in 8-10 weeks) It was pleasant to work with Anthony and McMaster. Very happy with our new HVAC. read more

We used McMaster to replace our old FAU - A/C unit on our home in Portola Hills several years ago. We were very happy with the service and equipment, and loved how quiet and energy efficient our new unit was. We recently purchased a home in need of major renovation in Laguna Niguel. James, Anthony, and crew were extremely helpful - we relocated the unit from the garage to the attic, put all new ducting throughout the home, and installed a new a/c unit on the side of the house. I've recommended McMaster Air to neighbors in the past, and will gladly do so again in our new neighborhood. read more

Hi Ron, I just wanted to say thank you for the AC unit. We love it and it works great. Your recommendation was exactly what we were looking for. It is quiet and cools the house down quickly. Your crew was fantastic and kept things clean. They showed up when the said they would. I love what they did in the attic. Of all the contractors I have ever worked with, and I have worked with a lot, this was the best experience I have had all the way around. Thank you very much. read more

My mother hired McMaster Heating and Air Conditioning based on strong recommendations and we are so glad we did. From the initial consultation to when they finished installing the unit in her home, they were amazing. All phone calls and emails that my mother sent had prompt and friendly responses. When providing recommendations regarding specific products to best meet my mother's needs, they stayed objective and were very considerate of my mother's life demands. As noted, my mother is 70 years old with a comprised immune system. Not only did they arrived on time during the two appointments and worked efficiently, but they also made sure all employees wore masks and booties. I would recommend this company to anybody who is interested in working with a professional local company. Thank you for treating my mother with care! read more

Dear Ron, Let me begin with a hearty thank you to you and your extremely professional staff for the recent complete home HVAC system replacement, upgrade, zoning & controls, and commissioning. This project started with Anthony - who truly listened to our requirements, understand our need to add zones to our home, and his ability to develop proper load calculations and models using the Carrier units best matched for our home, lifestyle, and interest in energy efficiency. His proposal was on target and he worked with us to refine it further as the full scope of zoning was better understood. We really appreciated Anthony's honesty, integrity, commitment to the project, and tenacity in sticking with the project from beginning all the way through the HERS testing. I want to also recognize Christina who kept us in constant communication and your world class installation crew of Mike, Kevin, and Carlos who were polite, always on time, and CLEAN!!! (I wish more contractors were as neat, clean, and caring about our home and wood floors as your crew.) Ron, the new ductwork these guys built on-site was of amazing quality. Mike, Kevin, and Carlos always showed a high degree of attention to detail. The proof was in the HERS test as the completed system performed flawlessly with less than 6% total leakage! To say that my wife and I are delighted with our new Carrier Performance / Infinity 4-ton HVAC system would be a tremendous understatement. We now wake up to a warm house without the annoying blast of super-heated, dry air we used to put up with in our old system. With the zone controls we can bring the downstairs temperature up 2 degrees in the morning while allowing those remaining in bed upstairs to sleep peacefully. We then bring the upstairs zone temperature up later once everyone. Smartly the cooling zone controls have achieved exactly what we were looking for as the system now delivers the volume of cold air exactly where we want it, when we want it, and perhaps most importantly quietly without blasting us in the face or back of the neck. In addition the outside condenser is not only very nice looking but far quieter than the unit we replaced. Frankly I think this Carrier condenser is one of the quietest home units I have heard in a long time. In closing - I am recommending McMaster Heating & Air Conditioning Inc. to my friends and neighbors. Please feel free to use me and this project as a reference read more

Great service, showed up on time, very professional, and the price was very fair! We will always recommend them

We are very happy with McMaster Heating and Air Conditioning. I called a handful of other companies and decided to go with Ron and I'm so happy we did. Ron and his team are honest and reliable and they did a fantastic job replacing our AC units. I will definitely contact them again in the future. read more

I had a heat pump installed for my rental condo in Laguna Hills. McMaster does top notch installation workmanship with quality Carrier equipment at a good price. This system is quite an upgrade over my previous hvac system. read more

We researched several options before choosing McMaster to replace our AC unit and water heater. They were professional and did a great job.

Our company has used Ron and his team just a couple of times but he has made a customer for life! He is honest, kind, patient and efficient. We know our clients are in good hands when we refer them to McMasters! read more

Yes, 5 stars! Excellent sales and installation. Ron's final quote and the delivered A/C and FAU were exactly what we discussed. Installation was very professional. Total clean up of areas (almost like they hadn't been here!). Can't wait to see a decrease in my utility bill! read more

I had gotten several estimates and McMaster's was the best. Ron was very professional and honest with me. I'm happy that we went with McMaster Heating and Air conditioning. I would recommend them to anybody! read more

They put in my new units, 3 years ago. When the fan went out, in a hot spell, they did their best to get it fixed immediately.

Several weeks ago, I had an Heating and A.C. company come to our home to have our annual system inspection. At the end of the "visit" I was informed that my heating system has become dangerous due to the holes and rust spots in my fire box, and it was stressed that I should not turn it on, ever! The tech sat down with me and presented a quote of 16k. to replace the furnace and to include the replacement of my A.C. unit. After he left, I called a friend in the plumbing industry, he recommended Ron McMaster's Heating & A.C. I called Ron, mentioned the referral, and he set an appointment with me that afternoon. He checked out the system, and said he'd respond later that day with a quote. When he presented the quote, it was half of the previous quote. We negotiated the financial aspects, set the install appointment, paid my deposit and waited for the install date. The crew arrived a 8 a.m., said the entire install would take till 3 p.m. The crew was very polite, and efficient, cleaned up when they finished and left just before 3 p.m. The conversations that I had with Ron's office administrator were excellent. She kept me informed with every step of the process. She was great, the crew was great, and Ron, was the best of all. He came out several days later to review the install and spent some time with me regarding the proper use of the thermostat. Ron and his company are excellent, and I've already referred Mcmaster's to several of my friends. read more

This review is way past due. As I should have put this up earlier. I know homeowners will agree with me when I say that finding a good contractor is no easy task. We have all been there. Company seems good upfront but the work quickly become sub par, phone call don't get returned, and it seems that you start to get nickeled and dimed after they start the job. Not to mention those times that we want to try to save a buck and it turns out to be a horrible mistake. This company is none of the above. Let me start out by saying I work in the trade industry. I do container crane maintenance and do considerable amount of electrical and mechanical work also including air conditioning. I take great pride in what I do and it shows in my work so i expect it to show in a contractors work in my house. In order to keep well trained and educated employees you have to provide them with a career not just a job. You have to follow the rules and McMaster does just that. They are not the company that pay there guys under the table with no benefits. These guys have uniforms, workman's comp, training, ect....because when a guy is working in a 120° attic shoved in the corner you want him taking pride it what he does and not just throwing it together. I had a full a/c system installed in my house and had several quotes. Some of the contractors just walked in my house came up with a size unit took 15 mins and Gave me a quote. (This was Costco) McMaster did a full load calculation based on my house and gave me a emailed quote the next day. After meeting all contractors and with my background i knew hands down no question about it that I was going with McMasters. Theses guys are honest and top notch. Use them you will not regret it. Out of all the contractors I have had ever work on my house and looking at every aspect of a great contractor i have to say I was most impressed with McMasters heating and air conditioning read more

Back in Feb 2010 I was shopping for center AC for my house. I went to carrier website and only look for authorized dealer with platinum service. 4 companies show up in my area so I decided to call all 4 companies for bidding. Among with all other 3 bidders Ron from McMaster did offer me most cost saving plan and suggestion. He is very easy to work and give out very useful information as far as type of equipments, optional package and installation date. He also provided me the necessary information for my tax return and rebate information. Now the AC is been installed for more than 3 months and I am still very happy with it. read more

I wanted to share my experience with McMaster Heating & Air. Last December I decided to replace my furnace and A/C unit as my original furnace went out after 45 years of service. I worked with James Maloney on the pre-sales side and picked the top of the line furnace, A/C and Filtration system offered by Carrier. The products were all installed in one day's time. That said, there was some minor damage done to my crown molding during the installation of new vents/returns. Ron McMaster the Owner, got involved and brought in a contractor to fix my crown molding immediately. This was done within 2 days of my system being installed. Furthermore, Ron the Owner came out to fit my vents/returns personally around the crown molding to ensure that the finish work was impeccable. This type of Customer Service is something that most companies lack in this day and age. I would HIGHLY recommend Ron McMaster and his company for your heating and cooling needs. They are the only contractor out of 5 that I received bids from, that do proper testing before and after installation to ensure my system is as efficient as possible. They also processed all rebates on my behalf making the experience all that more enjoyable. Thanks to the whole McMaster's team for all of their hard work and dedication to my satisfaction! with gratitude, Josh Ward read more

We used McMaster to replace our HVAC and they were amazing. Our heater broke during the coldest part of the winter and the crew worked really hard to get the new system installed as quickly as they could. In fact, they stayed until 7:00 on New Year's Eve so that we would have heat on New Year's Day. The crew is great and all of Ron's leads are experts at what they do. We got several quotes and I feel like McMaster was the most honest in terms of what we needed, and we ended up saving money. Don't go anywhere else for your HVAC needs. read more

I recently had McMaster air replace my older a/c and furnace with newer more efficient units,what a difference why didn't I do this sooner! I highly recommend them. read more

I got estimates from 7 different vendors. McMaster was not the most expensive nor was it the least expensive. However, they were the most thorough and professional. I found them by searching for the Carrier website for Carrier dealers. I also read their reviews on Angies List and Yelp. I'm very happy with my decision to use McMaster. They installed a new furnace and AC unit for me. All of the 3rd party testing came out with flying colors and the system is working well. I even had them change out the new thermostat with a fancier one and did not receive any pushback or compliant. They were very accommodating. I would definitely recommend them to anyone who is looking to upgrade their system. read more

We just replaced our two 20-year old 3-ton air-conditioning system units with top-of-the-line 2-ton Carrier Air Conditioning/furnace Units. The contractor we used was McMaster Air & Heat in Irvine, CA. We couldn't be more pleased with the services they provided. All the people we dealt with are professional, knowledgeable, friendly, and competent. This was a four-day job that included an initial leak test, load calcs, complete attic reducting (including new air returns in multiple rooms), new compressors, post-install leak test, etc.. They arrived everyday on time, and left the house very clean. The Tustin City inspector was very impressed with the work done, and signed off the inspection in minutes. Our house leakage went from 7ft0 to 1.9ft0 - below the required number of 2.1ft0 allowing us to get all possible energy rebates. Overall, a great job! read more

We just installed a brand new heating and air system with McMaster. Ron, the owner, bid the job. We liked him and his bid came in under the other two companies who had bid the job. The crew, led by Jaime, were clean (drop-clothes and booties the entire time), considerate of our family and especially our dogs, and overall went above and beyond our expectations. They ended up redoing the entire duct system in our attic which was not included in any of the other bids we received. Don't even think about it....call McMaster. Professional, great pricing, quality crew. read more

We have had the pleasure of working with Christina Dietz and Ron McMaster to have air conditioning installed in our son's home in Laguna Beach. The permitting process in Laguna can be challenging. Christina's patience, kindness and professionalism got us through the process, long distance, with remarkable ease. She and Ron helped us to select the unit that met our needs for cooling, efficiency, and low sound emission from the condenser. They replaced duct work, and installed the unit and air cleaner, which are now treating our son to cool, clean air. He is a newly allergy-free and comfortable happy camper, and we are all delighted. McMaster's pricing was fair and appropriate. We had an excellent experience working with Christina and Ron, and would highly recommend them to anyone looking to install an air conditioning system. read more

I got my AC and Heating unit through McMaster Heating and Air 2 years ago. Yesterday, my AC unit wouldn't turn on. I sent an email to Ron (the owner) with pictures of the fault showing in the display. He recommended I reset the switch at the main circuit. I did and it worked. I am very happy with the customer service provided by this company on numerous occasions. read more

I had McMaster install an air cond. in a rental home in may 2015 and they did a good job. I have waited until now before writing a review as i wanted to see if we had any problems. Through all the heat this summer not one problem. I am very satisfied and will use them again. read more
