El técnico fue muy profesional y contestó todas mis preguntas. Llegaron a tiempo a la cita. Creo que el costo del diagnóstico fue justo considerando que los llamé un sábado en la mañana y llegaron a la casa ese mismo día en la tarde. 100% recomendados.

I called in the evening with air conditioner suddenly not working and he came over immediately and fixed it. Very appreciative of his quick response.

We have used M.O.E. a few times now and could not be happier ... Last Thursday we had an appt. schedule to clean and serviced our system. When they opened up the unit evidently we had a power surge and there were burnt wires so since we have a home warranty we had to deal with the warranty company before continuing. Brett turned off the unit so no more damage could be done, once the warranty company denied our claim (of course!), Brett and his Dad came back the next day, did all repairs and got us back up and running!! If you need small repairs, replacement of the whole unit, or general maintenance I highly recommend these guys! They were a godsend getting our unit back up and running very qui8!

We got both units, heater and A/C installed by Mark a few years ago and it was a great experience.
This time we needed to replace some parts from the condenser and we got them installed the same day and with no issues.
He has always attend our calls and we got his support since the beginning when our old unit failed.
Thanks for your service Mark and team.

What a team! I had an AC emergency and they worked with me to find a way to
fit me in the schedule. They were able to diagnose and repair in the same day. Thank you Mark and Brett!

Yet again, Mark and his company are the best around. I wish Mark did more than AC/Heat because he deserves your business. You will not be disappointed with their work. In a world of greed and evil. Mark is a good man that is doing his part to make Arizona a better place. Honest and professional every time. They have my business for life.

Very professional, efficient, trusting, fix problem, very easy to talk with. Met the owner and very friendly and knowledgeable and shared knowledge with us to better understand our system. We are life long customers with coming out twice a year to check out our system for a reasonable price.

Came out when no one else would be able to for 2 weeks, even though we had no AC. Peter P was awesome, did the work and answered all our questions and kept us in the loop as to what he was doing.

Mark is fantastic. Honest, up front and kind. If you need an air conditioner guy pick Mark and move on with your day. Even coordinates with renters to make it easy for everyone. 6/5 stars!

You can tell Mark has a passion for the business, he hustles to find customers in every day interaction and I 100% respect the hustle and grind. I met him for a non-hvac transaction via Facebook Marketplace. Mark tosses me his business card and now he is my families hvac guy. Great service, great prices, and friendly staff. Anyone who gives this man less than 5 stars is crazy.

Newly retired and living in my AZ home again, I called Mark to service my AC unit -not cooling. He was friendly, helpful and thorough. Now, 4 yrs later I knew it was time to replace my 22 yo unit.I called Mark. Once again, he was friendly, helpful and thorough. He lent a window ac for my bedroom unti a new AC could be installed. His installers were just like him-friendly, helpful and thorough. This was a positive experience from beginning to end. I’d recommend him to anyone!!

I just had an A/C installed. I liked that they would send everything electronically and follow up over the phone. The owner and son made themselves accessible and answered all questions. There was no pressure to buy or purchase a service contract. They will meet with you at no cost and assess the project.

The installers were on time and neat. They covered my stairs and kept me informed on the progress. David was the lead and was patient with me answering all my questions and explaining how the new unit works. Everyone was professional I would recommend them.

This week the time came for us to replace 2 4ton Heat Pumps for our home … I remembered that a friend had great things to say about working with Mark of Excellence Heating & Air conditioning . I reached out to Mark and hours later the company was in my home, the options they provided were all great, made sense and we felt good about moving forward with them. We felt so good about the experience that we severed an existing business relationship with one of his competitors. Mark of Excellence will be our guy moving forward!!! Thank you Mark

I highly recommend Mark for his exceptional service. He arrived promptly within 15-20 minutes, and provided efficient, friendly, and professional assistance. His pricing was also very reasonable. Additionally, as a gesture of appreciation, he offered a veterans discount to my father, a veteran. We are grateful for his thoughtfulness and excellent service. Thank you, Mark!

I am so grateful for Mark and Brett! They came out to my home the very same day after calling them. I have not gone with anyone else since they respond so quickly. When it came down to installing a brand new unit, I only waited less than a day. They are very affordable high quality guys. I cannot thank them enough! Highly recommend!

Another prompt, professional job by Mark of Excellence. First service by Peter, but same knowledgeable, thorough service we’ve come to expect from this local small business. Well done!

I am totally pleased with the service I receive from Mark and his workers. When I need his service, they are prompt, friendly, professional and very polite. This is the only company I want to work with for my heating and air conditioning services. I trust what they do and charge. Mark put a new system in for us almost 2 years ago and it has been great. Service warranties are good too.

6/24/25 update - Called Mark of Excellence at 7am because our house lights were flickering at times. Brett came out within 2 hours to check our unit since a failing capacitor can cause that at times. Brett determined the capacitor was still fine and the flickering house lights wasn't because of the AC causing a heavy current draw. Very responsive and courteous. Definitely someone I feel I can trust.

9/16/23 update - Our AC decided to quit cooling, again on a Friday night. Sent Mark a text at 6am Saturday morning, hoping they could accommodate us on a Saturday. He replied back in less than an hour and arrived shortly after. He had us up and running in about 20 minutes (capacitor had failed). Very prompt, friendly, and reasonable pricing. I would definitely use them again.
*****
I called this company about a year ago on a Saturday morning because my AC wasn't cooling. They got out that afternoon which was great, I expected to have to endure the AZ heat until Monday. The tech (Brett) found a condenser had gone bad. I happened to have one that the previous resident had left so the tech installed it and only charged me a reasonable service call.
Then last week, about 9:30 in the evening, we had a momentary power blip and everything turned off and right back on. I noticed the AC wasn't cooling after that. Called Mark of Excellence again and he said it was probably because of the off and back on power dip. That will load up the compressor so it won't cool properly. He told me to turn the unit off for 30-45 minutes, then turn it back on. That solved the problem and saved me the cost of an after-hours service call. You can bet I'm going to call them anytime I need AC service! Great folks,
