Mark Of Excellence Heating & Air Conditioning

The ac in my new construction home in Casa Grande was not blowing any air. I felt that it had to be an issue with the thermostat so I reset it several times and tried to redo the settings. But it was not blowing any air after 2 hours of many resets and swearing in 99 degrees in my living room.

I called Mark and they were able to fix it. They said the thermostat was installed incorrectly and there were other issues with the wiring. Mark said he will have a technician fix one my dripping pans in my home in Phoenix. My Scottsdale AC guy didn't even want to try to fix it and he lives down the street from me.

Had my AC go out today in a rental. Spent half the day trying to work with my home warranty to find someone before they authorized me to find my own contractor. I decided to reach out to Mark because he had good reviews, though not many, but still better than most in the Casa Grande area.

I called him around 4:45pm on a Saturday, he was out and diagnosed the issue by 5:20, a bad condenser fan motor and bad capacitor. He was very patient as I worked with the warranty company for 15 minutes. I got the approvals and he started working. He finished around 7:20pm and everything was working great. Tenants were very happy.

Mark answered all my questions I had and was very thorough with everything. His customer service is top notch and I would not hesitate to use his services again. He was very honest and did not upsell me, in fact he was straightforward and gave the recommendation based on my personal circumstances and what would be best for me, even if it wasn't the most expensive option, so I appreciate that.

For the amount of work along with the parts I thought Mark was VERY reasonable. For an emergency after hours weekend call he didn't charge any extra fees or anything. No service charge, emergency charge, or administrative or anything. He just charged me for the capacitor and motor fan. He provided the price upfront and at the end that was what I paid. No bait and switch or any tactics.

We have called Mark on multiple occasions now. He has diagnosed the problems within a few minutes. He takes the time to show you the problem and explain every way of how to fix it. Prices are very very fair. Highly recommend for all A/C or heating needs.

Mark showed up after contacting him at 9pm. Family was visiting so I really needed to get my ac fixed. Mark came ASAP and was very professional and quick. Got the AC working after 15 mins. Great service! Highly recommended.

Middle of July the AC broke on our rental home.  The tenent reported it at 10pm, but most AC repair shops don't open till 8am.  They got us scheduled for the next day but when I called back to see if they could fit us in before night fall, because our tenent has a 10 month old infant, they said they would likely be able to.   I very much appreciated their willingness to try to respond more quickly!  That week was record breaking 120 degree heat wave so I know their techs were overworked, but they were still willing to jump hoops and work overtime for us.  That is the kind of attitude that wins customers over!  Thank you!

Talk about a man of skill, integrity and great customer service. I highly recommend Mark to service your AC unit.

I had a warranty issue which was more of a manufacturer issue....112 degrees and they definitely are getting tons of calls, no problem as Mark & Brett were on the issue in less than 12 hours. I can't say enough about these guys and their responsiveness. They are first class and treat your call as it's the most important request they have. You can't go wrong with Mark of Excellence!
