Review

While being serviced I also had a “class in session” moment with my technician Mark Hilson😂. He taught me a lot about how to treat my system better as a first time home owner. I was doing an awful lot of things wrong and neglecting my poor system until it got fed up and left my family to die😩. He was a second opinion btw because I didn’t feel comfortable with the other company and I was right! They tried to get me out of $2000 to do absolutely nothing that was gonna fix the problem! All my system needed was a good cleaning and now we are back in the AC. This company is the most reliable and trustworthy I’ve run into. Thank you! Will be doing further business in the very near future.

I had a great experience with DJ and TE Certified. I had a Tesla charger installed by DJ and got a quote for a whole home surge protector. I was able to get a quick appointment with DJ. He was able to work around my schedule. He gave me a call to confirm and showed up on time. DJ is such a professional! He is very nice and polite. He is patient and explains everything and answers any questions I had. He is very knowledgeable and does great work and a very clean installation. While he was here I asked for a quote for a home generator hookup and he was very familiar with this type of project. I will definitely be using TE Certified and requesting DJ as my Technician.
