My last review was in June of 2022. I'm still here! I just had my attic HVAC unit serviced due to a leak. They're almost done with the job. They responded to this job like all of the others...promptly. I watched this house built in 1996 and Xtreme has been the only company to take care of my HVAC/AC equipment. It's still working well. On one occasion, Mark told me that I didn't need to replace equipment just yet, which turned out to be a big moneysaver. After all this time, I can trust them for cost of services and equipment as well as the way they take care of business. Thanks guys.

Great company. They came out the same day I requested service and fixed the problem right away. They did not try to upsell me or try to sell me an entirely new system. The technician, Matt, was professional and knowledgeable. 10/10 recommend.

Matt came to investigate a heater issue with rain water being backed up in our flute. He was super quick to diagnose and propose very honest solutions. He was very objective on how to best approach the problem. Lucky for us, the solution involved some pretty straight forward fixes. He didn't try and sell us on some unnecessary solution but instead found a creative middle-ground fix for us. He was super knowledgeable on all aspects of the heating system and very thorough in his assessment. I would recommend Matt and Xtreme Heating & Air Conditioning to anyone. Great experience and very fair cost. Highly, highly recommend!

We had a home in escrow and discovered a problem with the blower fan. They were prompt to respond and had the problem fixed immediately at a excellent price. We have used Xtreme Heating and Air Conditioning for years while we lived in Corona. Great people, great service!!

My parents, elderly, house hallway was full of water. Mainly when the air conditioner was on. Contacted Xtreme Heating & Air and received a quick response. They were on-time and knew exactly what they were doing. It is fixed and no more leak. Now restoration company can do their job. Thank you for your quick response and fixing the problem.

Extreme Heating and Air had serviced the heating and air at our home for 16 years, so when it came time to look at new equipment they were one of three companies that we contacted. Mark was very competitive and his crew recently installed a new heat pump system which means we no longer will have those high winter bills for natural gas and lower electric bills during the summer with the more efficient unit. Thanks to Mark and his crew of James, Sal and Angel who worked so efficiently to remove our old system and install our new on. We love it!

Super nice company to deal with on getting our new AC/Heating units. Very reasonable and even finished our project in 4 days instead of 5. They truly went above and beyond our expectations.

We can't say enough of how much we appreciated their hard work from start to finish!

Virginia R., San Francisco, CA Via Yelp Testimonial


My technician is the best knowledgeable

Matt know his ac heat pumps. Would recommend this company because Matt is very professional

We opted to replace our 16 year old HVAC system, which had experienced some "issues". Mark initially visited our home to survey existing equipment and our needs then provided a very reasonable estimate in writing, which we accepted. Amanda, the office manager, is great to work with, and guided/scheduled the entire process. The installers.....Clint, Mike, James.... were outstanding, on-time, very respectful of our home and property. The tear out and installation was carried out rapidly, professionally. and cleanly, with very little disruption of our lives/routines.

Amanda then scheduled a HERS Rater test (required by the State) for us, pulled permits, and scheduled the final inspection...all without a glitch. The new system works beautifully....much quieter and more efficient than our old one. We would HIGHLY recommend Xtreme and it's staff...they are consummate professionals.

Larry F., Winchester, CA Via Yelp Testimonial


The last company who attempted to fix our heater 10 yrs ago said we needed a whole new heater. At that time, we couldn't afford a new heater so we went to Google online and fixed it ourselves. When my heater broke this time, I was worried that I would be told to get a new heating system again.

I called Xtreme and they said they could come out in a half hour for my estimate! Unfortunately, I wasn't home but they came the next morning. The repairman knew exactly what was wrong. He patiently fielded multiple questions from my husband during the repair. He didn't just take the easy way out and tell me to get a whole new heating system. He fixed it and I'm nice and warm! He even said that I may save on my electric bill as a result of his awesome job repairing my furnace!

Very efficient and great workmanship! Fast and reliable!

Service cost less than half of the other five quotes

Excellent in all areas! Had Xtreme move my A/C unit from the back of the house to the side. Service cost less than half of the other five quotes I had. They will be my only phone call for future HVAC needs!

Thanks so much from a long term loyal customer

Hi guys,

I just wanted to thank you so much for what you did for my sister Bunny.

You saved her from being cheated by other companies who wanted to overcharge her. In addition, your service was terrific.

Again, Thanks so much from a long term loyal customer.

They have always come through with the right solution

As a Contractor, it's vitally important to work with other contractors you can trust and rely on. Xtreme Heating and Air Conditioning are exactly that type of business, trustworthy, knowledgable and they follow through and complete their job with excellence and passion. Anybody can drive around in a truck and throw AC units together and make promises that are not kept. It takes a real professional and friendly staff of dedicated individuals to excel as a Contractor servicing Residential and Commercial clients. Whether it's trouble shooting, new install or retrofit and upgrade, they have always come through with the right solution. I've been working with Xtreme Heat and A/C since 2008 and they continue to always do an outstanding job - every time ! Give them a call - you won't be disappointed.

Their dependability and professionalism, along with the quality of the work performed, is why I continue to do so

I have known Mark Born for the past 11 years and have done business with Xtreme Heating and Air Conditioning for as many years. During this time, I have referred their services to many other communities throughout the Inland Empire. Their dependability and professionalism, along with the quality of the work performed, is why I continue to do so. During our last company picnic, while all employees were over 100 miles away from their communities, an emergency arose that had to be attended to right away. I immediately contacted Mark and although the community in question was out of their normal service area, he sent a technician to do the work as a courtesy to myself. I have been in the Property Management industry for over 15 years, and I have never come across another HVAC company with more integrity and exceptional customer service. I have and will continue to recommend Xtreme Heating & Air Conditioning to anyone with the utmost confidence.

Suzi E., Trilar Management Group

I wish there were more stars to give!!

I can't recommend this company enough!! I wish there were more stars to give!!

We bought a new house that had the AC on the fritz. It was well over 100 degrees and no other companies would come out for at least 2 weeks.

Mark was at my house within 2 hours and had it diagnosed and fixed in an hour.

Thank You So Much!!

Todd F., San Diego, CA Via Yelp Testimonial

I never have to worry or give much thought to whether or not they will be on time and take care of the problem.

This is a letter of recommendation for Xtreme Heating and Air Conditioning Company. I have been using Xtreme for my HVAC needs for 3 years. They have been great to work with. They are one of my best vendors. I never have to worry or give much thought to whether or not they will be on time and take care of the problem. I have the owner's number and when I need an answer to a problem that can be fixed in house he is quick to give technical support over the phone. With that said, I feel very lucky to have a relationship with Xtreme.

Brian S., Equity Residential

Xtreme Heating & Air exceeded our expectations

We were a little shocked when we first discovered the need to replace our over 30-year old AC system. However, Mark explained in detail what we needed and why we needed it. From there, his installers did exactly what Mark said they would. As the very professional installers went through the two day task of replacing our old unit, we saw what 30 years would do to a heating & air conditioning system. When the installation was complete, we experienced an immediate and drastic improvement in our climate control. Three days after the installation was complete, Mark came by and checked the work, and explained the future maintenance to us. Xtreme Heating and Air exceeded our expectations in the installation process, the savings on our utility bill from having a more energy-efficient system and the improvement in climate control our new HVAC system made! Many thanks to Mark Born & his friendly and competent staff!

Look no further than Xtreme Heating & Air Conditioning

To any potential customer planning on installing a air conditioner or heating system in your home. Look no further than “Xtreme Heating & Air Conditioning, Inc.” Located in Temecula, CA. (951) 698-3600. We had a brand new system installed on 7-20-11 at a cost no one could match or come close to. The installers were very professional, courteous, and did a clean job. Our system is working better than I ever expected. Give them a call. You will not be sorry.

John & Alice, Murrieta, CA

We want to thank Mark and your installation team on an extremely pleasant experience.

The care they took in installing our system including the zoning was outstanding and the system works wonderfully. We look forward to working with your company in the future maintaining our system in the same way. You are welcome to have others contact us so we can again express our total satisfaction.

Dan & Barbara B., Grand Terrace, CA

I recommend XTREME heating and air!!!!

I really appreciated XTREME heating and air and the tech Ryan who came out this week to look at whether we could move our air conditioner to get better efficiency. He was professional and honest and not trying to convince us of anything but very honestly told us our conditioner was too small for the size of our house. While we could not afford to purchase anew one and being of advanced age, we knew we had no option on this. But so thankful to Ryan for his honesty and understanding of our situation. While we could not buy another one, I will definitely not hesitate to call him should we have a breakdown. I recommend XTREME heating and air!!!! Thank you!

Wendy S., Murrieta, CA Via Yelp Testimonial

In Love With Our New AC

I wanted to let you know how happy I am with the new air conditioner you installed. Your installation team did a great job and cleaned up every day. The new unit works so much better than the old since you made some changes. In these days of disappointment with many services, your company went above and beyond expectations in updating our air conditioner system. Since our neighbor referred us to you it looks like you have two very satisfied customers in Grand Terrace. Thanks again for doing a wonderful job.

Mike K., Grand Terrace

Xtreme Heating got us an appointment right away

Our upstairs heater went out. Xtreme Heating got us an appointment right away. The service tech that came out was on time, very polite and knowledgeable. He was able to troubleshoot the problem right away. Though the part he needed wasn't on his truck he called around and found it available in town. He scheduled the follow-up appointment to work around my schedule. When he returned he was not only on time, but he was early. I will definitely use them when it is time to get the air conditioner serviced for the summer. I highly recommend Xtreme Heating and Air!

Happy With Heating and Cooling System!

Amanda, I'm very pleased with my new heating and cooling system. Ron, Mark and Travis were great throughout the installation project. It was obvious that they are skilled in their trade. You are lucky to work for such a superb company. I am glad I chose to go with Xtreme Heating and Air Conditioning.

I Just Wanted to Say Thank You

I just wanted to thank you all for the great job you did on the Suite in Murrieta. I know that the job got very demanding at the end but I really appreciate you guys coming out on such short notice to finish things up. Mark, you have a great team working for you and you all are a pleasure to work with. I look forward to working with you in the future! Again, thank you for the great job!!

Nicole, Murrieta

Thank You Xtreme!

Hello ! Ryan came out this morning to work on our mini-split unit that had not been operating efficiently. We wanted to let you know that we were very impressed with him. He was very courteous, quick and had our unit up and running fast. We will recommend your service and Ryan. Thanks a lot.

Steffi and Mike Korte

Everyone is really impressed

Everyone is really impressed with the work that Ron and his crew did upstairs. This is the first summer where the server didn't overheat - and even on the hottest days it never got above 78 degrees in that area.

-Patrick Astleford, Rayzist Photomask, Inc.

Quick diagnosis and repair

Matt Peterson was our technician. He arrived promptly in our service window and quickly diagnosed our problem. He also cleaned and checked the performance of our A/C unit. He called the office to get an accurate estimate for parts and labor for our needed repair, and the office called within two days to schedule service once they received the part. Matt returned to complete the repair, again within the service time window, and quickly repaired and tested the unit.

We have been extremely (no pun intended) happy with our Bryant system that Xtreme installed over 12 years ago. They did an excellent installation that was worth every penny and more, and the unit has worked fantastically until this first repair incident in 2020 (actually the unit was still operating, but had a failure code that wouldn't clear). We would highly recommend Xtreme for all you heating and cooling needs!

-Jeff Dunn


Thank you to Mark and his team. They did a excellent job moving our air conditioning units. They were very friendly. His team checked everything thoroughly and cleaned up after the job was done. I highly recommend this company.

Thanks for doing an amazing job

We've used this company several times for both repairs and an install of a new unit. The guys are very knowledgeable. The new unit worked wonderful all hot summer long. My daughters complained it was too cold in the house. The house is now evenly cooled, no more hot rooms in part of the house. Thanks for doing an amazing job.

We have used XTREME for a few years, they have given us excellent Service each time, but today I had them over to check out the heater I must say that they (Ryan) surpassed any serviceman for his service And knowledge, not to mention his attention to our problem.

Take 5 stars now,and another 95 for being the best.

Don S., Temecula, CA Via Yelp Testimonial

Thanks to technician Matt for his professionalism

Had Temecula XTREME do my yearly ac checkup/maintenance last April and this second week in June has proved the wiseness in that. Thanks to technician Matt for his professionalism and noticing and closing an opening in wiring conduit that gave access to insects, etc.

Best service and knowledgeable in all aspect of HVAC work.

I have used XTREME in my home since 2006. Best service and knowledgeable in all aspect of HVAC work.

In addition, my family owns a couple of commercial buildings and we have been using XTREME since 2006. XTREME came highly recommended by a special inspector. Their professionalism and knowledge of both commercial and residential HVAC is amazing.

I will continue to refer XTREME Heating & Air.

The office staff at XTREME Heating & Air is always able and willing to assist.

Thank you XTREME Heating and Air for the great service you have provided me and my family.

Treated my family like it was theres

Great company to work with, came out explained everything to me that they wanted to do. We worked on some things added a entire new system as well as replaced all the Duct work in the house. Showed up on time ever day and cleaned before leaving. Treated my family like it was theres which was comforting for the wife. Over all great experience, new system works great, had an air flow issue and they were out in a day or two and adjusted everything to make the house perfect in all the rooms.

XTREME Heating and Cooling gets 5 stars from us. Our heater was down during a cold spell and XTREME was on it. From "Hello, how can I help you" to "Thank you for your business" we received excellent service and care. We found our technician Matt very knowledgeable and skilled at his profession. Start to finish we had a wonderful experience with XTREME. Thank you guys!

fixed our problem and their pricing was very fair.

I've hired XTREME Air a couple of times. We live out in a rural area in the Unincorporated area of Hemet and most companies will not service us because we are too far out. XTREME showed up on time both times, Ryan was so helpful and fixed our problem and their pricing was very fair. I highly recommend them and Amanda is Awesome to deal with. Great Company!

Kimberli H., San Francisco, CA Via Yelp Testimonial

Always excellent work. Both office and Techs are very professional. I have had them out multiple times. Always have the best price and do great work. I wouldn't call anyone else.

Scott C., San Diego, CA Via Yelp Testimonial

They are very reasonable and friendly.

We needed to move our AC unit from one of the side of the house to the other. XTREME heating and air was recommended by a good friend. They came out and did everything in one day, and did a great job! Fast foward several years later, our AC had been working great and then all of a sudden stopped. I did not hesitate to call EXTREME again. They came out the same day and were able to figure out what the problem was and fixed it. They are very reasonable and friendly. I will not hesitate to use them again.

Dan C., Irvine, CA Via Yelp Testimonial

Technician was courteous and professional.

I used XTREME to perform an inspection and "tune up" of my heater and air conditioner unit. They arrived when they said they would, and the Technician was courteous and professional. I would recommend them.

Geoff S., Temecula, CA Via Yelp Testimonial


I would highly recommend XTREME Heating and A/C. I called them after AC quit working. Amanda did a great job in scheduling both Trent and Matt to fix our AC problem. I believe this company does a great job in taking care of its customers. All very knowledgeable about the business. Our AC problem has been fixed and out Unit is running great.

If you are looking for a fair and honest company to solve your heating or air conditioning problem call XTREME.
