Call to Discuss Your Indoor Air Quality Options Customer Reviews ONE OF MY BEST EXPERIENCES WITH A CONTRACTOR 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. Ryan W., Irvine, CA Via View All A PROFESSIONAL, WELL COORDINATED TEAM THAT DOESN'T TAKE SHORTCUTS. McMaster installed a 2 tonne central air, 3 tonne central heating, air purifier and attic insulation in my 1930's home. They were confronted by challenges at every turn that required solutions that a seasoned professional would know that met local building code. They showed up promptly each day and worked quickly and as well coordinated team that managed to complete the install in 3 days in spite of the complications. I read many reviews on Carrier equipment and concluded that the install and comissioning of the system is at least as important as the choise of equipment. The installation is neat and as unobtrusive as possible. McMaster came highly recommended by a neighbor and friend and now i am happy to continue the recommendation.

I highly recommend both Ron and his crew. They are extremely courteous and professional. All parts of the transaction; the quote, scheduling, installation, orientation to the new products, and cleanup after the job was finished were all handled by trained, uniformed, courteous crew members. It has been a sincere pleasure to do business with Ron's company. Ray J., Fountain Valley, CA Via HAD A GREAT EXPERIENCE Had a great experience. Did what they said they would do and left the place clean like they had never been in my house. Would highly recommend them joan edwards Via WE HAD A GREAT EXPERIENCE! They installed a small split system in our Adu, and a bigger system in our home. They were incredibly reliable, professional and reasonable. We had a great experience! We highly recommend them! Ana B., San Clemente, CA Via AMAZING! 10 OUT OF 5 STARS What a great company! Thorough, attentive, polite, and knowledgeable. They installed a complete new HVAC system, including new duct work, in my 66 year old home. Everything is great! Had an issue during our recent 10-day extreme heat event and they came to service the A/C unit in less than 4 hours after I called -- AMAZING! I give this company 10 out of 5 stars. Lorrie Stratton Via MCMASTER WAS THE ABSOLUTE BEST CHOICE I shopped a/c companys for more than 2 years. Hubby didn't think we needed it! McMaster was the absolute best choice. Owner Ron accommodated all of our needs. He and his installers were nothing short of professional and we are thoroughly enjoying our new furnace and a/c unit. We got the top-of-line carrier unit and are so comfortable all year around! Hubby is loving it and I'm healthier and allergies have greatly improved. If shopping for a/c, look no further. McMaster is the ABSOLUTE BEST!!!!!! Diane W., Capistrano Beach, CA Via HIGHLY RECOMMEND! High recommend, installed a new HVAC system quickly and efficiently. Eric Fults Via MCMASTER IS A STRONG TEAM . . JUST TRUST THEM!! Absolutely, McMaster is a strong team, especial Ron! He is your decision maker who always think about his customer. I won't do other choices just trust them!! Kay Y., Irvine, CA Via MOST IMPRESSIVE OF THE BUNCH 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. B I., Irvine, CA Via AC PROBLEM DIAGNOSED AND UP AND RUNNING IN THE FIRST 20 MINUTES Our AC was not working. We originally had another company out who was "stumped" on the problem, "needed to sleep on it," & complained the entire time he was in our home. I haven't dealt with any AC companies yet & this was an awkward experience. Our landlord then called McMaster. Alexis easily set up our appointment & was very friendly & professional on the phone. Our tech Anthony showed up extremely early in our time frame which is not always common in service of any kind which was GREAT! Anthony is definitely amazing & skilled at his job. He had our AC problem diagnosed & literally up & running within the first 20 minutes of being here. I was so shocked at how fast Anthony got everything going again considering the last tech from the other company was here for hours. He was very professional, informative, answered all of our questions, & was very friendly. He was finished within the hour & we have AC for the coming hot Summer months!!!! We are so thrilled with the amazing experience we had with McMaster & I am so excited to have our AC back!!! THANKS ANTHONY YOU ARE AWESOME! Joy J., Lake Forest, CA Via GREAT EXPERIENCE! TOP NOTCH PROFESSIONALISM We were very pleased that we decided to work with McMaster Heating and Air to replace our A/C and heating system in our home. Ron was very professional, knowledgeable and a pleasure to work with, as was the entire staff and installers as well. D S., San Juan Capistrano, CA Via VERY HAPPY WITH THE WORK QUALITY Very happy with the work quality on installing new AC system. Very professional installers. Very helpful and attentive staffs. Han Chen Via VERY HELPFUL IN GETTING OUR OLD AC WORKING I chose McMaster heating & Air last year after trying several disappointing companies. I found them honest and reliable. They were very helpful in getting our old AC working (before a terrible heat wave hit) as they couldn't fit us in for our installation for a couple of weeks. All the guys are clean, and professional. I trust this company and the Carrier product they sell. This AC unit is so quiet and efficient. We are happy! JB Costa Mesa Janet B., Costa Mesa, CA Via I AM VERY HAPPY WITH MY CARRIER SYSTEM Last summer, I obtained four quotes for a replacement AC and furnace. I did a lot of analysis to figure out the kind of equipment and size of unit that I thought would work well for my home. When Ron McMaster came to my house to give me the quote, he was patient and answered all my questions (and I had a lot). Of the four quotes I got, Ron provided the only one that included the size and kind of equipment that I believed that I needed. The price for the system was fair, IMO. It was not the cheapest, but it included everything I was interested in. And I appreciated that McMaster is a Carrier factory authorized dealer. The team that installed the system was led by Anthony. Each member of the team was very professional and hard-working. They made sure to clean up everything at the end of each day. Anthony was super knowledgeable. There was a loud rattle which I hadn't noticed in my original system because that system was so darned loud. But with the new Carrier system being so quiet, we could then hear the rattle. Anthony ultimately came back and replaced some kind of pipe, eliminating the poorly-routed one from the original unit's installation. Anthony was so patient tracking down what was causing that loud rattle - I was very grateful. Anthony also took time to explain the new thermostat to me. I requested that Anthony place the thermostat in a slightly different location from my original one, resulting in a hole in the drywall from the original thermostat. McMaster arranged for a person to patch and repair the drywall, which I appreciated. Additionally, Jennifer and all the office staff were very kind and helpful in all our interactions. Now I have a quiet system HVAC Contractors in Irvine, CA | McMaster Heating and Air Conditioning, Inc.

As a local, family-owned HVAC company serving Orange County since 1996, we have earned the trust of thousands of satisfied residential, commercial, and industrial clients and earned numerous positive online reviews for our exceptional workmanship, extensive industry knowledge, and dedicated customer service. Our team of HVAC specialists excels at installing, repairing, and maintaining heat pumps for year-round comfort. Heat Pumps: Orange County’s Best Choice for Year-Round Indoor Comfort Heat pumps are an excellent HVAC option for Orange County’s homes and businesses. A heat pump can be ducted (central air) or ductless (also known as mini-splits ) and provide both heating and cooling. Unlike traditional heating and cooling systems that generate heat or cold air, heat pumps work by transferring heat between indoor and outdoor environments. This unique technology works particularly well in mild climates like ours. As a result, heat pumps are considerably more energy-efficient and environmentally friendly than HVAC systems with separate air conditioners and furnaces. An Eco-Friendly & Energy-Efficient Heating and Air Conditioning Solution At McMaster, we have over 40 years of experience designing, installing, repairing, and servicing ducted and ductless heat pump systems for Orange County homes and businesses. Because heat pumps are one of the most energy-efficient and eco-friendly options, they often qualify for rebates and tax credits . When designed properly, heat pumps can meet the demands of nearly any residential or commercial space, from room additions, server rooms, and garage conversions to entire homes, multi-unit housing, hotels, restaurants, and commercial buildings. Carrier backs their heat pumps with a one-year 100% satisfaction guarantee when installed by a Carrier Factory Authorized Dealer. They also offer a limited parts manufacturer warranty for ten years. When you have your heat pump system installed by McMaster Heating & Air Conditioning, you’ll also get an AHRI Efficiency Certificate confirming the exact efficiency rating for your specific HVAC system.

This unit's unique, variable-speed compressor allows it to adapt its output to the home's needs. With tiny adjustments between 25 and 100% capacity, it gives the home only the amount of cooling or heating necessary.
