This is the best A/C company in our area. I can't say enough good things about them. They installed my old system and... when it was time for a new system, we went with a high efficiency system plus new ducting. It is amazing and I am so happy. Their price was at least $5,000 less than other A/C companies in our area. Their service over the years has been excellent and they have always done the repairs in a professional manner for a good price. I highly recommend this company!!!!read more

We cannot say enough about Steve Allison and his top-notch crew, Junior, Phung and Victor. Outstanding job designing... and installing a 2-zone Carrier Air Conditioning and Heating system for our specific needs and comfort. Katie Allison in the office was very professional and efficient in getting all the contract and warranty documentation to us online, and setting up the HERS Duct testing and City permit and final inspection. All were very knowledgeable, personable and a dream to work with! And, the little thank you gift and cookies they sent at the end were a delightful surprise!read more

SHORT OF IT: Expertise (industry knowledge), honesty, sincerity/genuineness, value of quality and integrity are how I... would sum up Steve, his company and their offerings in my experience of them.THE LONG OF IT:There are certain purchases in life where these factors above always should come first, above anything else, especially expertise and sincerity, if you're looking to spend thousands on a brand new AC, Furnace, Duct and HVAC system (in my unique case). Without expertise and deep knowledge of industry or profession, saving a few bucks here and there could cost me a ton of money down the line.What I love most about Steve and his company during this process of evaluating different HVAC companies here in Southern California is that Steve will give you the recommendations that make the most sense for your home and your specific situation. Some of the other companies I am evaluating have withheld information or withheld making a helpful recommendation to me because they wanted to keep costs down hoping I would just sign with them, one company even pulled a gimmick like "Hey! Sign within 24 hours or the price I quoted you goes up!" I'd rather actually be told what would be the best situation for my budget, rather than someone not telling me something helpful because they think I'd be turned off by spending a little bit more. Specifically, in my case, no other company prior to Steve told me about the benefit of adding additional returns to the house when replacing a Central Air HVAC system. I am a voracious reader and someone who does extensive due diligence when it comes to anything in life, especially big purchases, I researched Steve's suggestion extensively online and learned that various HVAC experts throughout the country also said the same thing for my unique situation, confirming what Steve had told me. Can't express enough how appreciative I am of that. Only 1 other company after Steve's company made a similar suggestion. When I went back to a previous company I'm evaluating sharing with them the idea of adding additional returns, they admitted "Yea, I have 5 in my own home, sorry I didn't make that suggestion, wanted to be competitive with the bid."In my experience thus far, Steve and his company actually want you to make the best choice for your home and he is one of the most GENUINE people about the whole process and what is best for your preferred needs and situation. It gives me assurance that this is how they would do business whether it's a simple maintenance call or service call or in my unique case installing all new HVAC equipment after 25 years of having the original builder-grade stuff in my house. All the homes in my neighborhood are older, built in 1990's originally with all original builder equipment, my neighbor Kevin, who is also upgrading his home's HVAC (with a much more complex and technologically advanced setup with zoning, etc than what I'm looking at) is the one who told me about Steve and Allison Air Conditioning in the first place. Glad he did!One more thing I love about Steve, he follows up and follows through when you connect with him on questions, and he is detailed/thorough, this may seem standard, but there are two HVAC companies in this So Cal region that I met with that didn't even do that. All these seemingly minor factors add up and reveal how a company does business and the quality of what you'll be getting.Sincerity, expertise, honesty/integrity, and follow-through are always some of my primary personal factors, would recommend Steve / Allison Air on just those factors more

The service was fast, friendly, and efficient. All of the technicians were very personable and professional! It was... like doing business with family. There was no pressure sales pitch and they were very knowledgeable about their craft. They were extremely accommodating and attentive, and they promptly responded to my calls. They courteously answered all of my questions even during the installation--explaining the process--and they didn't act as if I was bothering them which I appreciate a lot! They weren't rushing through the job but took their time and made sure it was done right! I would definitely do business with them again and I would refer anyone in need of their services!! Thanks guys!read more

We had our 20-year old system repaired by Ken - he was efficient and professional and had us up and running in no time.... Our experience was so good that we ended up going back to Allison Air to quote a new HVAC system a couple of months later. Steve provided a thorough quote and explained the options and his recommendations - he offered information and no pressure. We met with several other contractors, but our decision was clear and we went with Allison Air. Katie took care of our scheduling and paperwork - everything went smoothly. Albert, Manny, and Ken installed our new system. They are obviously very experienced and work together like a well-oiled machine. Taking Steve’s recommendations on what to purchase worked out perfectly - our new system was tailored to fix our air flow issues and now we are very comfortable in every room. We highly recommend Allison Air Conditioning for repairs and new installations. You’ll get the best service from a trustworthy company. Thank you, Allison Air Conditioning!read more
