We have had the need to use Allison air conditioning a few times over the last couple of years. Every time they have been extremely professional, polite, and most importantly trustworthy as they repair and share about what needs to be done with our AC and heating. We recently had them do a very large project of replacing AC and they did a wonderful job. The great thing is the job took the amount of time quoted and they put the manpower necessary on the job to make sure that it was done quickly. It was also done with great respect for our home. They were very clean and very polite throughout the entire time. We are happy we found this company and will always faithfully be using them for any of our services that our AC/heater might need. read more

great team. Fast response with awesome results. Kept work area clean at all times. Steve really knows his business and helped guide us through the selection process. read more

I just had Allison Air repair my heater. I called and got a repairman the very same day. It was extremely cold in my house and Freddie did an excellent job getting my heater to work the same day. This is my second time working with them. They are courteous and professional. I highly recommend them for your heating and AC needs. Thank you again Freddie! read more

I have been using this company for years. Steve, the owner is excellent and he employs the best people to do the job. I have had many services done by them. They installed my new air ducts and new heating and air system, as well as my air purifier. Their Techs are knowledgeable, very polite and do a great job. If you call them you will probably be speaking to Katie. She is great to work with ; she does all the scheduling and helps you with any of your service needs. This company goes above and beyond to help you with getting your heating and air up and running. They are THE BEST! read more

Bad services. I wouldn't recommend this company. Very high in prices. Technicians are very rude when trying to explain what's going on with the system. read more

Fast service and great owners with good follow up and availability of appointments.

We have used Steve Allison's company over the years for our home's HVAC needs. He provided service to our old system, replaced our furnace/cooler (anticipating the future need to upgrade the condenser), and most recently replaced our ancient condenser with a new, state-of-the art Carrier condenser and thermostat. As with our past experiences with Steve and his team, this most recent installation didn't disappoint. Steve was personally involved from start to finish. Albert, the installer, and Ken, the technician who teamed up on the installation did excellent work. They were friendly, thorough, neat, highly competent, and professional. Both the area outside where the condenser was placed and the area in the garage where the furnace is located were immaculate! Steve and Allison Heating & A/C Serviced proved again why we continue to turn to him for our HVAC needs! read more

I got proposals for a new A/C (16 SEER) and furnace system from three Carrier authorized experts (two Award Winners), one Lennox dealer referred by Costco, and one "other" dealer. Only Allison's provided a "straight up" detailed itemized list of the exact Carrier equipment and services that they would provide. Not only that but every Allison's team member that I spoke to from Kenny the salesman, to Katie the office manager, to Junior the lead installer provided me with excellent information. The more I talked with them the more at ease I became with my first-time, major purchase of an A/C and furnace system. They were never condescending and always helpful. And, judging from the smile on the Home Energy Rating System (HERS) inspector's face, I made the right decision. The HERS inspector confirmed that Allison's installation was very well done. So, ultimately, Allison's won my business because of the positive comments about them on the internet; their respectful, affable, and helpful demeanor; their straight-forward, itemized list of the equipment and services they would provide; the 5-year parts and labor warranty; and the fact that they have been doing business for 33 years. read more

The technician Victor did an amazing job. Very friendly, knowledgeable, and thorough. Gave us confidence that our system will keep us cool through these hot times. We will definitely continue working with them in the future. read more

We called the Friday before the 4th of July weekend to have the AC unit checked at our 85year old aunties house. Steve was fantastic! He responded the same day, was kind to our Aunt, and didn't over charge her! He did what needed to be done today, made recommendations for what should be done in the future and the time frame for doing it. I can't say how much we appreciate an honest business owner! Definitely recommend you give them a call!!! read more

Referred to me by my neighbor across the street who went with Allison Air Conditioning for a full brand new HVAC install including zoning. 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. Doesn't rush you in your process. 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, who is upgrading his home's HVAC (with a much more complex and technologically advanced setup than what I'm looking at) is the one who told me about Steve and Allison Air Conditioning in the first place. He highly recommended them. 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 alone. read more

We highly recommend Allison Heating & Air for your HVAC needs. We recently replaced an existing 30%year old HVAC system with a larger unit. The house is an historical Craftsman bungalow with unusual characteristics and, much to everyone's surprise, the old unit's duct boots were all improperly installed. In addition, the new unit had a defective part which was not easily obtained. Allison employees adapted to all these problems & issues with efficiency and good humor. They responded well to any special requests, answered all our questions & even took pictures of the unit in the attic for us. The house looks like it has never been touched, no debris or cleanup necessary. The system works well, much more efficiently than the previous one. They did an exceptional job overall & we would use them again. read more

If I could give them 10 stars I would. They moved my 2 AC units and were extremely professional and reasonable. Very honest. Would highly recommend. Thanks so much Allison AC!!!! read more

Thank you, THANK YOU ALLISON HEATING AND AIR. You went over and above with service and PROMPT response and installation. The employees were neat and tidy. Compassion and polite. We are thoroughly satisfied and ecstatic That we have a cooling system thats quiet and easy to operate . SO GLAD we didn't have to wait another summer and buy more fans- They're financing options presented quite a few options COMMUNICATION with Katie and Steve was a 10+ FIVE STARS FOR ALLISON HEATING AND AIR read more

See all

I had a great experience using Allison Air Conditioning. I am a local realtor and very picky on who I use. I got two quotes from other companies and Allison had the best price and value for what I was getting. We bought a 2 ton Goodman Air handler which went in the attic and a 2 ton condenser outside. They also upgraded our return intake duct and installed a new thermostat. They showed up with three guys in two nice trucks, they crew looked clean and professional they worked hard and got it all installed by the end of day. Jr, the lead installer is so calm and smooth and Phung was great too. Brad helped Jr and they cleaned up all areas where they worked and laid down a drop cloth. Phung made sure my condenser platform was level and I appreciated that they didn't rush to install they took the time to do it all right. I will definitely refer them to all people and use them again. 10 Stars read more

Allison Air was referred to us by another air company that does not service Eastvale. Our air conditioner was making that horrid sound where you knew that you were going to be informed it was something expensive by the repair guy. Initially, we called another company, and WOW they were trying to overcharge us...and that's a gross understatement. We (thankfully) called Allison Air. They were able to come out ASAP and provided a free estimate (already different than the last company that charged $100 for a guy to come out and to see there is a problem, and then he had to schedule another guy to come out to relook at the AC unit and quote us). The quote from Allison was extremely fair and exponentially better than the initial quote. The quote matched the final cost, yay no hidden fees. They said they would show up between 8-9am, and they showed up at 8:05! The same guy that gave the estimate did the work. Have already recommended them to friends. In summary: Friendly On Time Professional Honest Well Priced read more

Great company great people they are professional organized friendly and efficient you don't need to go anywhere else go to Allison Air Cond and they will take care of you and your family read more

I am giving these people 0 stars but Yelp does not allow me. I was waiting all morning for these people to show up. I finally called them to see what is going on. They changed my schedule for the following day without calling me to tell me. I took the morning off from work. Very unprofessional. If they dont show up for their appointment, I wonder how they handle doing their job. read more

Excellent service from this company. The service technicians were knowledgeable and professional. Glad I called them. read more

Allison A/C and Heating sent a technician out to check our A/C which had stopped putting out cold air. The young technician was honest and forthright about not being able to fix it but said that his boss, the owner of Allison, would be out the next day. The owner came the next morning as promised. He was able to fix the relay to get the A/C compressor working again, fixed the fan that was making a loud noise, and installed a programmable thermostat for a total cost of $385.00. Both of them were extremely professional, honest and ethical. We highly recommend this company for the reasons stated above. We will always call them when we need repairs or service in the future. Thank you for your great company. read more

I have been working with Steve and his crew for four years now but he has been servicing our commercial building for at least 10 years. Allison Air is honest and reliable. They perform the quarterly servicing, all of our repairs and all of our HVAC unit replacements. They recently upgraded all of our thermostats, too! read more

The BEST!!! Do not call anyone else these guys know what they are doing. Clean courteous and friendly and the best pricing I have found anywhere. You got my referral "GREAT JOB". read more

Richard from Allison Air Conditioning came out to troubleshoot our non-working unit and did a very thorough and honest job. He spent a lot of time explaining things to us even though it was Friday night and I'm sure he wanted to go home. We knew we needed a new unit and he didn't try and waste our time and money with additional time and diagnostic tests. Would highly recommend them to anyone. read more

Found Allison Heating and Air through a friend and I'm so happy that I found Steve and his crew. Steve came over and did a very detailed inspection of the house taking pictures and making many suggestions to improve the flow of air for my size home. We ended up putting in a completely new system along with new ducking and relocating the furnace into the attic. It was a 5 1/2 day job, but totally worth it. The crew of Jeff, Albert and Mark came to do the install and were excellent. They are knowledgable, cleaned up daily and were always open to whatever I had them do. I would highly recommend Steve Allison and his crew if you need a new system. Thank you Steve!!! read more

Allison has been my go to company for several years for all my HVAC requirements from maintaining my older system to the recent install of a new HVAC system. Steve, Kati and their workers are all very knowledgeable and dedicated to meeting their customers requirements, be they large or small. Their work is exceptional! I have recommended Allison Air Conditioning to many friends over the years and will continue to do so. read more

Steve is phenomenal. He always goes out of his way to provide great service. They're honest, dependable and will always have my family's business! An additional note, the office is always very pleasant to talk to and gets us booked and taken care of! Thanks, Allison Air! read more

Anyone looking for an air conditioning company that comes highly recommended, look no further, Allison Air Conditioning receives my highest review for a job well done. I believe a company is only as good as its owner and Steve is the best. Having been disappointed that my Carrier air conditioner and furnace system that we spent over $10,000.00 to install lasted barely over 10 years (not installed by Allison Air) we researched companies and decided to go with Allison based on many discussions with Steve that indicated that he ran an honest and reliable company. Having just had a knee replacement and being required to sit in a CPM machine for 6-8 hours a day in addition to doing 30 minutes of physical therapy 3 times a day, I was not looking forward to suffering through this in 100+ degree weather with no air conditioning. In rode Steve on his white stallion (Okay, his white work van, same thing) to the rescue. I don't know how he worked his miracle, but within 2 days of leaving a message on his phone about which air conditioner we had chosen to replace the broken unit, he had a brand new one in and working like a charm, giving me no more excuses with which to make for not doing my knee recovery program. I was very impressed by Steve's installers as well. On the morning of installation, Jeff, Albert and Mark arrived ready to go. The first thing I noticed was that they were extremely respectful. Every time they had to come in and out of the front door, they opened and closed it completely and quietly! This may not seem like a big deal to some but we have cats that are indoor only so as not to become coyote fodder. I was expecting to have to keep watch over the front door as inevitably, someone always forgets and leaves it open a crack for the cats to escape and the flies to come in but this was not the case with Allison Air. I did not even have to mention it once and they had to come through the house many times. The ultimate test was that one of my cats, who is a big chicken, never sticks around even when family comes over. He typically heads straight under the bed. Imagine my shock when I realized that he had fallen asleep in the living room and did not hide. This has NEVER happened! These guys were so respectful and quiet that he was not threatened, very impressive! And last but not least, Steve arrived to show us how to work our fancy new thermostat, and test the unit to ensure that it was working properly and that all was well, which it was and is. But I have absolute faith that if we have any issues or concerns, all it will take is a phone call to Steve to handle them. Oops! Almost forgot a very important point. We were given a vey good and fair price for the work that was done. I was a bit nervous that with the temperature rising, we would get reamed with a huge bill. Didn't happen. We couldn't have been happier from start to finish with Allison Air. It restores my faith to know that there are still honest and dependable contractors out there with integrity. read 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

They replaced our air conditioning unit in July. It worked fine for a few weeks. When we came back from vacation, it wasn't working. I called them and let them know. They came out the next day. The problem was not related to their installation but they fixed it anyway. They could have easily put us off for a few days. We are happy with the unit and great customer service. read more

If you are looking for a company for installing, service, or repair for air conditioning and heating look no further than Allison Air Conditioning and Heating. In fact, they're the only company you need to call. Steve (Owner) and his crew installed a new Carrier furnace and air conditioner two years ago and it's unbelievable how great the unit is performing. The Carrier Unit with the 16 Seer Condenser is so efficient that it's able to cool my 2350 Sq. Ft. house at a fraction of the cost as compared to my original unit. It's like Porsche performance at Honda prices and efficiency of a hybrid. With the recent 100+ degree temperatures in Corona lately, I'm very happy that this unit works so well. read more

I turned on the heat for the first time this year, and what a racket! I turned it off right away, and made some calls. Allison Heating & A/C sent someone out the next day. Tanner came in an recognized the noise right away, but wanted to try out some of the easier solutions first. After testing the system, it turns out, he diagnosed the problem correctly. Steve, back at the office, worked up an estimate, and ordered the compressor compatible with my system. And Katie, kept me informed throughout the process. Tanner installed the compressor today, and ensured the system worked perfectly for both heating and air conditioning. What a difference - the system is whisper quiet, and every room a comfortable temperature. I would absolutely give them a call, if you're in needed for trustworthy, and competent support! read more

Steve has been my AC guy for many years . He has done service , repairs and upgrades in my home . He does good work and on time . He always cleans up behind himself. With that said his pricing is fair . read more

What can I say. There is a reason for all the positive reviews for this company. I received service yesterday on my system. Richard from Allison called in the morning to confirm an appointment window and the service tech (Ken) was on time and called me when he was on his way. Great start....gets better. Ken was clean, polite and explained everything he was about to do and very open throughout his diagnosis. He was very thorough and methodical. He did not try to pressure me to buy things that were not necessary. He narrowed the problem down to 2 potential causes, and even suggested we try the less expensive of the two and said if that did not solve the issue he would come back out at a discount to install the more expensive part should the first procedure fail to resolve the issue. Who does that these days? I will tell you, an honest company, that's who. It was a complicated issue but the first procedure appears to have worked so I am a happy camper. My system is over 20 years old and I know it is just a matter of time before it gasps its last breath, but when I need to install a new system, guess who I intend to call? Hard to find honest people in business these days but this one is a gem. If you are indecisive about who you are going to call for your service, look no further. Allison Air, you have a great tech in Ken, a good ambassador for your company!!!! read more

My first impressions were good. Steve was very informative and was open to my concerns regarding our new unit. I had new ducts,ac, gable fan in attic,and furnace installed with permits. It took 5 days for install, but ran into a problem when one of the installers foot went threw my ceiling. That repair job took another 2 days. The installer apologized and checked to see if we were satisfied during the repair process. You could tell it really bothered him , guess it doesn't happen as often as you might think. It passed inspection and airflow check. The new system works great , no complaints. read more

These guys are the best. Superb customer service. Steve is great. We had a last minute emergency and they came out the next day to take care of this. read more

Best AC Company I have ever worked with! The owner Steve is so easy to work with and is very honest. His employees follow suit also. We have used this company for the past 6 years as they help us get through a few summers with our old AC and they also installed our brand new Carrier AC along with a new furnace, vents and return. They did a wonderful job! I totally recommend them if you are in need of AC or furnace work. read more

I have always been very satisfied with Allison Air Conditioning. I have 2 air conditioners , one upstairs and the other downstairs. My downstairs ac had been giving me problems for a couple years and they would always come out and recharge the freon for us. We didn't want to pay the huge cost of a new system because we heard it would be around $10-$12,000. We finally got a quote from Steve, the owner, and it was way lower than we thought. We were shocked. They installed it in a half day and we are now extremely happy with our new ac. The guys that installed it were very professional and friendly. Would definitely recommend Allison Air to anyone that needs ac repairs or replacement. We plan on using them again when the upstairs unit goes out. read more

I waited until we had a 107 degree to test the system Allison A/C installed last April. It works perfect. So,if integrity, creditably,honesty are important to you, then Steve Allison is the man you want to deal with. Allison A/C designed and installed a new system complete. Absolutely everything was replaced. The old stuff was hauled out. And I couldn't be happier. You may be happy if you go with the cheep guy, truly a shot in the dark. I'm positive you'll be happy with Steve, he's one of the good guys. read more

I decided to hire Allison Air Conditioning due to many Yelp's positive reviews. Most reviews mention honesty which is quite rare to find these days in this cutthroat business. I want to confirm that Steve, the owner is an honest man. Of course, every job site is different and mine did experience a few hiccups but Steve responded quickly to resolve any problem. Pricing was reasonable and Steve was willing to provide financing options. I ended up with two awesome systems installed. Thanks Allison Air Conditioning. read more

My house is only five years old and we've live there for only four. We had an issue with the A/C shutting off unexpectedly and had another Air & heating company come out (for the third time in a year) and they told us the compressor was about to go out and would need $4500 to change it out. Given that, I called Carrier headquarters to see if my unit was still under warranty and it was. Carrier gave me the numbers of a couple of folks in my area to call, and one was Allison Air. I needed a second opinion, and also to see if I really needed a new compressor. Richard, the technician came out and was very knowledgeable, friendly and walked me through the process of him checking my capacitor and compressor to see if anything looked like it needed to be replaced. After spending about an hour or so, testing and inspecting my unit, nothing was found to be critical or even borderline. Richard also checked my thermostat and saw evidence of something that probably caused my unit to shut off the way it did. Richard did not pressure me to buy or have him replace the thermostat. I am pretty handy and have replaced several thermostats before over the years. Bottom line, I paid the service fee and felt that I was treated very fairly. Richard was honest and dependable. I recommend Allison Air Conditioning to anyone who is having problems with their A/C or heating. read more
