Jennifer Gonzales: 5 out of 5 stars (Super quick response for our AC that quit working on a weekend. Very reasonable pricing. Happy we found him!)

Greg Seigerman: 5 out of 5 stars (I used Mark to install a mini split unit for my media room. He did a great job and his pricing was aggressive. I had 2 other a/c companies bid my project and they didn't come close. My only complaint now is that my media room gets too cold! Great job Mark.)

Esteban Elizondo: 5 out of 5 stars (I’ve been with CoolMark for over 2 years. He’s an expert with a quick response time and the best prices.)

Julie Domser: 5 out of 5 stars (Came out on short notice after 5:00. Fixed our problem, did a lot of our cleanup, and did it all with a smile on his face! Rates were a lot better than I expected. He is at the top of the list if I have problems again!)


Jake White: Mark came out the same day we called him and fixed our unit. He is friendly, professional, communicates well and does a great job!! We had a second issue with or unit after he came out and he worked hard to accommodate our schedule and fixed it. We would recommend him 100% and will call on him again if we have any more issues.

Maria & Gisselle Montelongo-Salas: PROMPT, PROFESSIONAL and AMAZING service.. Mark and his team, came to the rescue. Thank you again for all hard work, getting our parents home cool again.


Roxane R.: 5 out of 5 stars (I wish I could give this gentleman more than 5 stars! In a house full of women, we tend to get overcharged or told we need more work done than we actually do. Not only did Mark come out on short notice after 5:00, he fixed the problem, helped with our cleanup, and had very reasonable rates! He will definitely be our Go To guy in the future!)

Richard R.: 5 out of 5 stars (CoolMark came out on short notice, blew out the drain line, and got my A/C system going on a Friday night.)

George R.: 5 out of 5 stars (These guys are just the best. I had tons of quotes that were outrageous and this company was reasonable and much quicker than anyone else I talked to. Able to identify and solve the problem in 1.5 hours when other company's were unable to tell me what was even wrong.)

Maricela G.: 5 out of 5 stars (Mark provided exceptional service. He arrived quickly and at the exact time he had told me to expect him on a very hot Sunday afternoon. He was very knowledgeable about my AC and found the problem. My AC was working when he left and he followed up with me later to make sure everything was working good. He was fair and honest. Will definitely use this company going forward.)

Melinda D.: 5 out of 5 stars (Mark called me almost immediately after I posted my problem. He arrived right on time.

I will be calling him again for future A/C and heating services.)
