Couldn’t be more thankful for a awesome company. Came out as soon as I gave Ernie a call. Came out gave my unit a once over let me know my pressure switch was bad gave me a couple options on how to fix the issue. Now my family is comfortable again and just in time for this upcoming heat wave we got. Thanks again to a great fast responsive respectable company.

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

Very knowledgeable and respectful technician. Technician came back out after reviewing system to communicate with us the service needs. Not pushy for sale...really genuine and wanting to help us the best way for us.

I have been with Semper Fi for about for years. Each and every time, the technician they sent was extremely professional, ethical, clean, And efficient. These people support our military, and they do an honest and excellent job. The technician who came out today was named Devin and was an excellent young man Who was highly skilled. I gave Semper Fi Mai highest possible reading, and hope they continue to hire such excellent technicians as Devin.

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.

Excellent service and delivery for our 6000gallon sodium hypo tanks.
