DM Mechanical Services Air Conditioning & Heating

My ac went out last night and I was able to message Dwight the next morning. He responded in 20 minutes that he could hopefully fit me in that morning, and would give me updates on when he would be heading to my house. Even after a holiday, he was able to fit me in and was very professional on helping us with our need of ac, especially with this Texas heat. He got it up and running in under an hour and he was very respectful, friendly and knowledgeable about the ways to help keep our unit running properly. Thank you, Dwight for helping our family!!!

DJ came out and looked over our unit that suddenly stopped working. DJ talked to me about the issue we were experiencing, took his time to diagnose the issue. He came out quickly and was able to get us up and running within a few hours. There’s a couple more things that need fixing but we can at least be warm during the cold weather. We appreciate the help from DJ and his respect.

We had a small leak from our indoor unit, and Dwight came in and checked for any issues, as well as answered our questions, and explained what he was doing. Super helpful being new homeowners, so that if something happens in the future we know what to check for. Thank you!

I guess in every review, you always have the one person who gives a company a 1 star review. This is the first time it has been me - i usually give companies 3-5 stars, never seen a company I had to do worse with. I am not sure if the issue is so much the company as the tech. I am not sure what the issue was, but he had been out four times (although the first time was an inspection). The tech was friendly enough, I really liked him, but the problem is, it has now been two weeks and the issue is still not resolved. He first told me I needed a cleaning, and scheduled an appointment for a week later for that. During the process, he knocked down the vent cover in the bathroom. After he finished, it was cooling off VERY slowly. I was able to get it down to 82 that night, woke up the next morni

I don't usually write reviews but I felt for this company I'd make an exception. Diamond M has been servicing and installing my HVAC systems for years. I haven't ever had an issue with the customer service, technicians, or warranty personnel. All have been a pleasure to do business with. Each time I've needed service they've made sure I get taken care and the job is done right the first time. I'd recommend this company and have referred them to several people that have been thankful I have for their expertise in the HVAC industry.
