Success Story Spotlight:

Lost about who to pick from a dizzying array of HVAC specialists?  Stop surfing and read this review!  Mike with Alliance HVAC was my choice after a year of research on HVAC and 8 competitive quotes.  I am an IT professional; no details go unnoticed; I am picky and high maintenance!  Not only was he the most inexpensive meeting my budget, but he gave me the most bang for my buck with a consumer grade 3 ton Rheem gas heating and air conditioning solution (pics posted on Yelp — Allied Gardens).  There was no prior AC; the job included removing an old furnace, building the system completely in the attic, and adding two vents on the far side of the house.

I learned about Mike through a friend; his business is a well kept secret (maybe not any more lol).  With Mike you get straightforward honest personal customer service, unlike a mega corporation that is more concerned with funding its advertising campaign, or evading accountability by sending unqualified technicians after you sign the contract.  In fact, out of 30+ contractors I have had renovating my 1968 home, including a $30,000 kitchen renovation I just finished, Mike (and his work partner) were the most thorough perfectionists, accountable, positive, communicative, easy to work with, and most courteous not to cause damage or disruption while doing heavy renovation.

I was at the house supervising during the entire job as I work from home.  I even explored the attic (which was not an easy or comfortable setting) with him to understand the work and decisions involved, which Mike explained and educated clearly. Mike has broad experience including gas, electric, roofing, plumbing, air flow, and structural integrity.  He has been part of a family owned HVAC company since his teenage years.  He can anticipate problems so that the job was done completely and correctly the first time, and when it was clear the best solution was going to take more time, patience, and physically demanding work, Mike of his own volition and without complaining put in the extra hours and effort, and even upgraded certain hardware at no additional cost to me.

As Mike is the owner and the primary technician who will quote and implement your HVAC solution start to finish, you may need to be patient from a scheduling perspective as his priority is for all of his customers (and their emergencies).  That said, he was always on time, or else communicating changes in advance.

You owe it to yourself to call Mike, get a quote, and see for yourself how he has set the bar with customer service and quality project implementation for the HVAC industry!

Update: 12/22. Heat and A/C still working perfectly…It’s a lifesaver!

"I called Alliance to fix the AC in my office, they were easy to reached, returned my call promptly, they showed up on time and fixed both of my AC units for the fraction of the quotes I had gotten from other companies. They were fast, efficient, courteous and very professional. They were honest and did not try to give me a service I did not need after I told them I know nothing about AC systems. I would highly recommended them to all my friends and family and will use them again in future. Thank you for making our office nice and cool again."

"Our AC unit went out during a heat wave. Other companies were 2 weeks out for an appointment. I then called Alliance and Mike was out within a few hours. He took 2 minutes to look at the unit was able to diagnose the problem and have it fixed and serviced within an hour. He was friendly and professional. I will definitely use Alliance again and highly recommend them."

"These guys were amazing!! My wife called them at 9 o'clock at night when our air-conditioner broke and Mike the owner answered the phone and was able to schedule an appointment the next day to come out and fix our air conditioner. Not only were they on time but they called beforehand to make sure that I was home and ready for the appointment which was extremely courteous. Once they were here they were very friendly and nice, they worked extremely well with dogs around and they were able to troubleshoot the problem immediately and find a solution. I even needed a part that they did not have on the truck and they immediately went out to the store and got the part and fixed my air conditioner. They did all of this with in one hour and the price was so reasonable that you absolutely have to call alliance if you ever have air-conditioning issues or want the best and most honest business owner in the air-conditioning business!"

"First of all, I’ve never had better customer service. When I called Alliance, Michael, was very kind and helpful. He answered all my questions and even tried to diagnose the problem over the phone. It ended up, I needed a new heating unit for my four bedroom house. Michael had advised me on which unit to get and installed it very promptly. I am very happy with Alliance Heating and Air and will use them for my shotty air conditioner when summer comes....waaaa waaaa waaaa. I would definitely recommend this company to a friend."

"our ac broke on one of the hottest days and we have a 3 month old. i called probably 12 places and mike was the only one willing to come out the same day. he arrived and fixed the problem right away. thanks for such great service mike!"

⭐⭐⭐⭐⭐ Yelp
"Short and sweet: I called several AC repair places and Mike was the only one who could come out the same day. Since this was an upscale rental property - I had to have it fixed "that day". He came out - He fixed it, was great with my renters and he gave me a fair price - I couldn't ask for more. I forgot to mention I am not local we did it all over the phone and email! THANK YOU, I would utilize AH&AC again and have recommended to to others."

"This small family owned business offers honest service and competitive pricing. They usually can't get to you for a few days because they are overloaded and don't work weekends so keep that in mind if you’re in a bind over a weekend. Other than that not being available over the weekend this is a solid company to do business with."

"Alliance Heating & Air Conditioning assisted with an A/C issue in an apartment after a leak a few years ago. I had such a positive experience that I held onto their card just in case and I'm so glad I did. My current A/C unit stopped working and I was able to get an appointment just a few days after I called (I'm sure this is the "busy season") and the repair itself took less than an hour. I'm so happy with their service, pricing, and quality. The owner, Mike, also spent time speaking to me about what I could do to maintain my A/C unit and keep it running for several more years. So grateful for a company I can trust!"
Carebot B | San Diego, CA

"If I could give 6 stars, I would! Quick background - 3 years ago I had a bad interaction with the company that soured my opinion of them. Since then Michael has reached out on numerous occasions to personally apologize and even offered to give me a discount on A/C related work Since I did not have any A/C work needed, I reached out to Michael to see if he could install a ceiling fan for my master bedroom - He offered to do it at half of what he would usually charge for the labor. He showed up half hour before his appointment and did top notch work; and also offered some tips on how we could improve airflow to our room - I'm very pleased with his workmanship and will definitely use Michael again for any A/C related work in the future."

"Our central A/C system stopped working over the weekend. On Monday, we paid "AirMaxx Heating & Air-conditioning" to inspect it and they quoted us $6,000-$7,000 to replace the system + the condenser. We freaked out at the cost, since we don't have that kind of money laying around. Our AC system is also only 10-years old, so it doesn't make sense there would be that large of an expense. Luckily, we had the common sense to call someone for a second opinion. Michael Rotter and his team at "Alliance Heating & A/C" came out on Wednesday and proved to be honest, honorable and knowledgeable! Not only did they say we didn't need to replace the system, but it only needed to be cleaned. Instead of it costing us $6,000-$7,000, it only cost of $249. Lesson learned? Always get multiple opinions for large quotes AND always make sure you call Alliance Heating & A/C FIRST. They are HONEST and understand the value of retaining repeat customers, for less money, actually makes them MORE money over time. We'll never call anyone else. Michael and his team are our go-to solution, as long as we live in San Diego. Thanks Michael -- you're an awesome person and professional. PS: We also learned that AirMaxx is either incompetent or dishonest. Quoting us $6K-$7K for a $250 job is inexcusable."
