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. It’s 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.

Today I came out and installed a New Exterior Sub panel and generator inlet on the right side of the house next to the meter/main. Instructions for use and demonstrations of use were done twice, once by my hands and verbal instruction and then again by Mr. Bruno’s hands guided by my instruction.

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.

Upon arrival customer stated she had a broken drain line outside that is messing with her foundation, stated it was broken by the lawn guys, upon looking at drain line, found broken, found water just falling right at exit point, causing water to accumulate near foundation, recommend extending drain line away from foundation, also recommend better flood protection such as wet switch, customer only wanted to move forward with extending drain line, added new drain line outside and secured to base so it can’t move, flushed drain line with water to verify draining properly, no other issues at time

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.
