Rae H from Tustin, CA  "Nate and all the guys at ABC are amazing. When we bought our 1965 house in June 2 years ago, the home inspection came back showing insufficient insulation and a lot of ducting connections in need of repair. Nate and his team did a great job repairing everything, which allowed us to get another 2 years out of the rusty AC unit that I didn't think would make it through summer.A few weeks ago, just as the weather was getting hot and I was 9 months pregnant. and due in a matter of days, multiple parts of our cooling system broke down. Nate and his guys came out ASAP and were super upfront about what was broken, how much it would cost to repair, and what kind of longevity (or lack there-of) we could except if we decided to repair instead of replace. We knew when we bought the house that the AC system was on borrowed time, so we decided to replace. ABC got our entire condenser replaced and running flawlessly in a day. Everyone we've met so far has been friendly, clean, and very honest. We'll definitely be using ABC for all our future HVAC needs.”


Krista M from Costa Mesa, CA "I will only use ABC heating and air. Not only are they priced fairly but they do it right the first time every time. In the past I have had to call them to fix what previous AC contractors had put in wrong or no to code. Never had an issue with these guys. Also very polite and service my units yearly.”

Mike B from Newport Beach "This is an extremely professional, on time, competent, tidy and respectful organization. Their work is top notch at a fair price. What more do you want?”

Valerie V from Huntington Beach "We had a great experience with ABC! We decided at last minute we wanted AC installed before 4th of July to get ready for the heat and help with air filtration due to all the fireworks in our neighborhood and ABC was able to get everything installed before the holiday weekend. They worked quickly and efficiently and also did a great job explaining things to us because we had never had AC before. Trustworthy guys and would definitely recommend any heating and air issues you have.”

Connor F from Costa Mesa "ABC always comes through! Whenever you have an HVAC issue, it always seems to come at the worst of times... so it's been nice to have these guys come out so quickly and diagnose / fix the issues. I trust these guys and would highly recommend using them for all your Heating and Air needs!”

Kirk S from Newport Beach "I HIGHLY RECOMMEND THEM!! Such an awesome experience with this company. I got 3 quotes for a new installation AC and replacing the existing heater. They came out and inspected everything to make sure to give me a competitive bid. They were not much more than the lowest but the equipment they were using was way better and Passed Newport Beach crazy noise laws! When they went to install it they found out that during my remodel a return air duct was disconnected and cut off in a wall. They asked for my approval and they cut into the wall and found and repaired the ducting! THEY ARE SO KNOWLEDGEABLE and helpful! I am beyond happy! If you want a professional company that has good prices and quality work then you MUST use this company!” 

Cait H from Newport Beach "During escrow we had ABC heating and air come out to inspect. The two gentlemen who came out were unbelievably thorough and Nate provided us with a detailed assessment and quote shortly after. I had lots of questions and Nate was very helpful in answering them and explaining all options. We ended up needing a new furnace, ducting and our AC unit cleaned and leveled. Nate and his team worked very professionally, quickly and thoughtfully throughout the process. Would HIGHLY recommend! Thank you!”
