Technicians seem to be pretty good guys when they finally reach you, that is.
Example 1. Furnace Tune-Up on an HVAC System. scheduled about 2 weeks in advance. The date rolls in, and nobody shows up, no calls, no voicemail, no texts, no emails. Calling them to check - "we called you yesterday and rescheduled". A load of ... untruth.
Example 2. They follow up on the generator installation estimate. I received two calls, two voicemails, two texts, and two or three emails. So they can reach me, huh.
Example 3. The Furnace Tune-up guy is here. Great experience all around - polite, professional, answered every question I had.
Example 4. Water heater expansion tank replacement. See example 3.
Example 5. Whole-house humidifier installation. Scheduled a week in advance. Appointment window 11 am - 3 pm. 2:10 pm, there is a call "we need to reschedule, they do not have a humidifier in stock, they will have one tomorrow .... we need to reschedule 2 weeks from now".
I hope my experience helps you make your decision

Dylan came out to reroute 2 bathroom fans that were not vented out of the attic. He walked me through the whole process of changing the ducts to insulated ones, installing the vents in the sidewall, sealing the area, etc. It was hard to find a company that does this specific work, and the price was very reasonable. Dylan and his partner were clean in their work, and they took away the old ducts for me at no extra fee.
I am also impressed with T-Mark’s professionalism and accessibility. They answered my calls quickly and arrived on time with notice beforehand. So if you’re tired of being ghosted by companies or contractors, give T-Mark a try.

Dylan from T-Mark was absolutely incredible. I reached out needing electrical work done, and he showed up the same day, even though it was his birthday. That alone says everything about his professionalism and dedication.
He handled the job quickly, explained everything clearly, and made sure everything was done safely and correctly. Super friendly, trustworthy, and really easy to work with.
Highly recommend Dylan for any electrical work. If you need someone reliable who goes above and beyond, he’s your guy.

We had some gas pipes moved and added. The price was competitive. Mike (& Jose) did a great job. We went over what they would be doing and when they finished Mike went over everything with us. We’re very happy with the work and would recommend T-Mark.

Outstanding Service and Professional Installation by T-Mark (Technicians Nick Trigilio & Ahmed)
I am writing this review to express my complete satisfaction and highly recommend T-Mark for any HVAC needs. From start to finish, the experience was exemplary, thanks to their fantastic team.
T-Mark sent technicians Nick Trigilio and his associate Ahmed to install a new Trane Heating furnace system, along with a new thermostat and a CO2 monitor. The complexity of this job was handled with skill and precision, demonstrating why they are considered highly qualified.
Nick and Ahmed’s professionalism was evident in every aspect of their work. They were not only incredibly efficient in completing the entire installation promptly but also maintained a clean and organized work area throughout the process. Beyond their technical expertise, both technicians were cordial and pleasant. Their excellent demeanor made the whole installation experience stress-free and enjoyable.
