Today is I arrived I came and installed a new customer supplied Tesla charger in the garage area. There was already a 50 EV outlet in the garage. I use the wire for the outlet to power the new Tesla charger. Once everything was installed, the Tesla charged properly once power was turned on. I also checked on a receptacle that was worked on by another company recently. The new wire had broken off on the backside of the receptacle. I reattached it and once that was done, the receptacle worked properly. It was very nice to meet you today! If I can ever help you with anything else, please feel free to give me a call anytime. Thank you, Brandon

Mr. Nathan Callaghan did an exceptional job with my HVAC check. He was extremely thorough, professional, and knowledgeable, taking the time to carefully inspect the entire system and make sure everything was operating properly. He explained what he was checking and answered all of my questions without rushing. I really appreciated his attention to detail and the care he put into the inspection. Its refreshing to have someone who takes pride in doing the job right and genuinely looks out for the customer. I would highly recommend Mr. Callaghan to anyone looking for a dependable and thorough HVAC professional! I will be asking for Mr. Callaghan going forward on any other HVAC issues that might arise.

I had a great experience with Marc. He was very kind and courteous. He was able to give me a quote rather quickly. He was very familiar with the faucet and water filter that I had ordered. The initial quote was a little out of my budget but he was able to work with me to get it in my budget. He did a great job and was able to install everything before I had to leave for work. This is the 3rd time I’ve used TE certified and the first time I’ve used their plumbing. I would definitely use them again.

Our water heater began leaking, we called on Saturday and were able to get an appt for Monday. Martin called and gave us his ETA and arrived exactly when he said he would. He was kind, knowledgeable, and efficient. The job was completed at a rate significantly cheaper than quoted by other providers faster than anticipated. They’ve definitely earned our business moving forward.
