Testimonials

Danny answered his phone and was prompt and very pleasant. He arrived when he said he would and the repairs were cost appropriate. I would recommend him to anyone.

Our first time using Sub Zero Mechanical. And we are definitely satisfied customers. Same day service, prompt, knowledgeable, fair priced and friendly. Highly recommend this company.

Danny was referred to me. He came to give me a bid and he was by far the most affordable with the best unit! Danny and his team came out and did a full install including vents in no time. They were all very kind and cleaned up very well! If you are looking for an HVAC guy, he’s your man! Thanks Danny!!

I had received quotes from 10 different companies and subzero mechanical provided the best price and a quality product. They were very professional, responsive, thorough, and courteous. They were able to install a new HVAC system one day after the estimate, they did great work and left my house clean. Highly recommend.

The owner of Sub Zero Mechanical, LLC (Danny) isn’t just a friend, he’s family. He cares about more than just your HVAC needs. He’s the epitome of Trust. Danny came out today and performed a service update on my Rheem HVAC unit that he installed in 2021. It feels like sweater weather already in the house! If you’re sick and tired of dealing with the big DFW HVAC corporate conglomerates and their outrageous prices & quotes, give Danny a call! I can promise that you won’t be dissapointed! Please support the locals that care about your comfort. Evan

We were referred to Sub Zero, by another trusted AC contractor that doesn’t service our area. We are very happy with the outcome. Danny was prompt and offered us a good system to replace our current old AC unit. The installation was very smooth, he explained things as it progressed, and we’re now enjoying a much more comfortable house. We’re looking forward to working with Danny in the future as our needs arise. I would highly recommend contacting Sub Zero for any AC needs.

Mr. Wywias and his crew did a fantastic job installing our new air conditioning unit. Super nice and polite young men. They were very neat and cleaned up everything when they were done. I highly recommend this Sub Zero for any of your needs. 10 Stars!

We worked with Danny on our air conditioning during the below freezing weather. Not only did he temporarily fix what was a thermostat issue, he also called our Ecobee and inquired about our warranty. We are now getting our thermostat replaced from Ecobee for no cost. Really appreciate him taking the time to call for us! Excellent service, will definitely use him again.

My 16 year old ac that came with the house had stopped working and Danny came out to help under my fix’d home warranty service. Danny was right on time (right at the start of the 2 hour window) and did an excellent job. I thought I was going to have to get a new unit but he fixed everything in under 2 hours. I genuinely wish I had called Sub zero (instead of metro energy) when I first moved into this house for a general check up. Metro didn’t do anything wrong, Danny’s service was just much better. I will be recommending Danny to my friends in the area.

Danny did an amazing job, so glad we had sub zero change our heating & ac unit. Definitely would recommend to friends & family!
