Testimonials

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.

From first meeting I felt a genuine trust and professionalism from Danny. Him and his crew got us in short notice and taken care of. Means a lot to a family with a baby on the way. Easy to work with and happy with outcome.

I saved a small fortune by trusting Subzero and Danny. I was quoted an astronomical amount to replace my entire AC system and Danny came to the rescue with simple repair. I could not be more thankful for the fair and honest service that was provided.

After bad experiences with two other companies, I was wary of the whole business. Danny quickly put me at ease with his professionalism and integrity. He brought in a crew of professionals who did excellent work in replacing a complicated system. I am grateful to a professional friend who recommended Danny to me.

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.

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

We had such a great experience with this contractor. He ensured that we were happy with the AC replacement provided after it was installed by the AC specialist. He is very easy to get into contact with and returns calls promptly. I highly recommend Sub Zero Mechanical. We will be using again in the future if needed.

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!

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

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.
