Best H E A T I N G And C O O L I N G in Phoenix AZ

Try to call them up for a appointment to get a estimate first time they screw up the date and set another time and date and once again nobody showed up .I would not recommend them since they can not keep a appointment time and show up and twice I waited at home for nothing

They are always professional and knowledgeable about the projects I bring to them. Darrell is the best!

We've used Scottsdale Air for many years now and have always been happy with their service. The office staff and the technicians have always been friendly and professional. In recent years, Scott has been our regular technician. He is a great guy and also very knowledgeable. We highly recommend Scottsdale Air and Scott!

These guys are amazing. We asked to check our air conditioning system. They found a problem in our filtration system that no one ever fixed during a routine inspection. They are honest and decent. I thank them for their excellent work.

Great service.

David did a great job of replacing 3 bathroom exhaust fans
Required him to be creative placing new fans with existing ductwork

Exceptional customer service and professionalism. Great communication. This is one of the best experiences I have had with a contractor in Scottsdale. You won't be disappointed if you call this company for AC services, repairs or replacement. I will be using them for all of my ongoing maintenance needs.

The office staff got technicians out immediately. The techs were very experienced and made sure they fixed the problem. When they needed to refer us to another company to take care of an issue staff followed up with a call to assure we had been taken care of.

My A/C stopped blowing cool air at 6:00 pm, it was 110 outside. Within one hours it was 84 inside my house. I call two providers leaving messages for after hour service needed. 911 Heating Cooling and Plumbing called back within 10 minutes and they were immediately concerned. A technician was dispatched to my house and arrived by 7:30 pm. I was so relieved to get such a quick response. It did not take him 10 minutes to diagnose the problem, he had the part in his truck and it was repaired and blowing cold air within 30 minutes. The price was reasonable and He was so courteous and kind. I am so grateful, and absolutely relish in my cool air. Thank you 911 Heating Cooling and Plumbing, your the best and I would absolutely recommend your service to all my friends and family.

New emergency service was necessary a year later. Again the response was immediate and they again were prepared to repair with the correct parts. It’s 115 outside today and my ac was back up and cooling within 2 hours. Thanks again ‼️‼️

12/21/21 Love these guys. They have helped me several times, twice when my AC went out, during hot weather. They responded so quickly and the unit was repaired within hours. They have also replaced my hot water heater, I did wait several days for that replacement, but understandably, I realized it was out on a Saturday. They do great work and reasonably priced, I have done the comparisons. Very personable, willing to explain and discuss options. I really trust and believe they have my best interest at heart. Thanks

Professional, honest, and polite! They quoted me at a fair and reasonable price for a new roof top packaged unit. They sat down and explained everything and in the end, it took about 3-4 hours for a completely new install. Definitely recommend them for any HVAC needs!!

Today we woke up to our upstairs unit blowing hot air and during this time of year that's NEVER a good thing! I called a LOCAL company who I felt was ridiculously over priced with their service call and yes I understand it's the weekend and I expect it to be pricey, but I'm certain most companies are not that high and I was right! After reading a few reviews from different companies I decided to call Semper Fi and I'm happy I made the call, from the professionalism of the answering service (Brittany) to our technician Tanner we could not be happier! Tanner was very responsive, professional and arrived at the time he stated, please note we are in PINAL County so we are not close to the valley, but I'm thankful they service our are and got our unit up and running! Thank you again Tanner, we will definitely be recommending Semper Fi to our friends and family!

If you’re in need of an HVAC company look no further. Jonathan and Sarah at High Efficiency Heating And Cooling are amazing and such a blessing. Can’t say enough great things about their quick response and willingness to come out diagnose, and fix my broken A/C after the first 100 degree day in Phoenix. Highly professional, knowledgeable, exceptional work, prompt, friendly, and most importantly trustworthy. So thankful I was led to this company. Definitely recommend them to anyone with an HVAC need.
