Jordana Siracusa

I highly recommend Associated Heating and Air. Everyone was professional. Came on time and got the job done efficiently. We love our AC unit. We found them through Costco and we feel like we got a fair price for a high quality system.

Wonderful experience working with Mr. Lam Tran. He is very helpful and trustworthy as he clearly explained all the details and make sure they are understood. I planned to get quotes from different contactors but decided to go with AH&A right after meeting Mr. Lam, our first quotation. Thank you very much so making this process such a pleasant experience.
Also, very happy with the professional installation by Victor and Leo. The whole HVAC system was installed in one day. They make the installation process seem effortless.

Levi Asuncion

The two main guys, Matt & Diego, were very nice to work with. They are very trust worthy fellows. My wife and I felt at ease with them during the whole installation process. They kept things clean and were mindful of covering areas that would get dirty from the work being performed. They notified us when they were going to make excessive noise, coming or going from the house, and keeping us updated of the installation progress. The work was completed on time and it all went smoothly. I highly recommend this company and its people.

Excellent from the sales staff Carlos to the install techs. Matthew was lead in our split install and he and his crew were on time, neat, polite, listened to my requests and concerns, and performed exactly as they said they would.
Also follow-up on real good. Coming from a Costco referral I would highly recommend Associated. You are welcome to call or write me for any install details.

It was a pleasant experience starting with a complimentary consultation with Ethan, through the Costco program. He was very professional, knowledgeable, and most importantly, honest. He evaluated our system and like the other reviewer said, giving us several options to choose. We ended up replacing multiple units of furnace and A/C throughout the house. Diego leads the installation team. The entire crew showed up on time and cleaned the working area every day before calling for the day. Diego very patiently answers questions during the installation. We are very happy with the service and will continue to use this company for any future maintenance. Thank you Ethan and Diego. Your team rocks!





I contacted Associated Heating & Air through Costco. I met with Ethan who did an assessment of our HVAC system, answered all of my questions, and was very thorough in his support. I was given a comprehensive proposal with different options and what I really liked was there was no pressure. Ethan continued to answer all of our questions and was always very helpful. We decided to replace our furnace and A/C. The installment team led by Diego were excellent and was extremely thorough. I didn’t realize how much needed to replaced as well as that we were out of compliance/not up to code since we had never replaced our HVAC system for more than 20 years. Working with Ethan and Diego and the team was a excellent experience. I found Associated Heating & Air to be such a outstanding vendor and really appreciated the professionalism. Our HVAC system works great and we’re very happy.

Technician Lam Tran came out and worked quickly to replace a starter in our condenser which immediately made both ac’s on each floor work like brand new. He was courteous, friendly, fast and kind. Thank you Lam for making this summer heat more bearable!



John P.


Dave Brown the manager, team of service people, and installers do excellent work. I have a mini split system installed in my attic with the compressor outside. The unit heats and cools very well and has silent operation. Dave personally visited my home with a technician to service my system and ensure it is operating correctly. The service from this team is OUTSTANDING! Thank you!



Robyn W.


I’m very happy with my ac unit and the service past and present. These guys break down the details I can understand from the way the unit works, the costs and financing. Thank you Chris Carillo, who came to do service at my house today, nice guy and showed me exactly what small parts needed replacing and why. I don’t part with my money easily, especially with the high costs of everything these days and they worked with me, do thank you
