Customer Testimonials

"Dave is the man!! I thought my A.C. went out last week and thought I was in for a huge bill!! It turned out to be a loose wire and he fixed it for free. How many companies would have tried to hit me up for a new A.C.??? I can bet you most of them for sure. Now he has a customer for life!! Thanks Dave!!"

-Jody, Queen Creek

"Dave found my problem when no-one else could. He was honest and cared that I am on a tight budget as a single mom. He took his time and did everything right to make sure we had ac so we weren't hot anymore! Can not express how happy I am right now and blessed to know that he cared and was going to get it right before he left regardless of what it took."

-Shelly, Mesa

“I used Mercenary Mechanical when I had a leak in my A/C unit. Their service was responsive, dependable and at a reasonable price. I have since switched from using a larger company to using Mercenary Mechanical for all of my heating/cooling needs.” 

-Lester, San Tan Valley.

"You won't need to find another A/C guy again!! We had a wonderful experience and we love their conservative, cost effective approach to cleaning, maintenance and repairs. They work outside of the Home Warranty bubble so they actually get the job right and done the first time. Timely, friendly, and excellent service. Thank you!! I've even recommended them to some other frustrated friends and they took excellent care of them."

-Courtney, Gilbert

“David did a fine job of explaining what he was doing, and what the unit specifications called for. He didn’t try to sell me any products that I didn’t need. I was very satisfied with his service package.” 

- Larry, Mesa.

"Mercenary Mechanical has serviced our needs timely and have done an outstanding job."

-Jeff, commercial customer


"Mercenary Mechanical was great. They came out right away, took care of the issue on our inspection report when we were selling our home. Prices were very good! Very friendly and professional."

-Cindy from Gilbert

"Dave was amazing! He fixed the things that the previous company didn't do quite right and made my AC safe. He even took his shoes off when he walked around the inside of my house (after telling him, that he didn't have to) lol. I appreciate you Dave! (and Angela) Ya'll are the bomb dot com!"

-Keilyn, San Tan Valley

"Dave has come through for us a few times. He did a AC inspection on a home we were purchasing and again when our AC went out. He was here in a flash, had the part on hand and fixed it right away. He saved us from the heat! I will be having him come out to service our AC on our other home once it closes escrow."

-Angela, Queen Creek
