Nick Addario has run Apex Mechanical's HVAC calls out of Saugus for eleven years, according to the company's own Thumbtack profile, mostly repairing and servicing heating and central air systems rather than doing new installs. The reviews people leave after hiring him tell a fairly consistent story: he shows up fast. In a November 2025 review a customer wrote that Nick came out the next day and resolved the issue quickly; a 2022 review described him fitting in a same-day look at a problem and staying clear about pricing throughout. Another from 2022 recounts him tracking down an obscure refrigerant issue in a homeowner's newly purchased house, complete with a warning that the previous owner may have overcharged the system before selling — the kind of detail that points to real diagnostic work, not just a parts swap. A separate 2024 review credits "Jeremy and his crew" with diagnosing a dead circulator pump and adding valves for easier maintenance going forward, and a January 2022 review describes working through a snowstorm to service two family properties, tracking down replacement parts and coming back a second day to finish deferred maintenance properly. Not every account is glowing. An August 2025 Google review describes a soured job: the reviewer says Nick went quiet after a leak turned up mid-job, so they hired a different plumber instead, and they're asking for a $200 refund. It's a one-sided account with no response on record, but it's a real complaint worth weighing against the pattern of praise elsewhere. Thumbtack's own numbers back up that there's some real spread here too: its 41 ratings average 4.2 stars, but 17% of them are 1-star — a wider negative minority than the individually quoted reviews suggest on their own. One thing worth noting: that 2024 review names "Jeremy" as the technician, while every other review on file names Nick. It's not clear whether Jeremy works alongside him or the review got attached to the wrong business. Before booking, it's worth asking directly how billing and follow-up communication work if something goes sideways mid-job — that's the specific gap the August 2025 complaint points to. For routine heating and AC repair, especially a system nobody else could diagnose, the record from 2022 through late 2025 leans toward fast and thorough.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Apex Mechanical. Use it to sanity-check bids, then get the real number in writing.

Nick was quick to respond and was able to come out the next day. He resolved the problem quickly and efficiently. I highly recommend him.
Hired for a job and had a leak! Hid behind his phone and Hired another plumber! You owe me 200.00 dollars
Jeremy and his crew are top notch. I have been using them for the past couple years for service and they are great. I called with a service problem thinking they would schedule it a week or even more out but Jeremy came out the same day! Not only did he come out, he had it repaired before the end of the day. Diagnosed the circulator pump had not been working, fixed it and added a couple valves for easier maintenance going forward. I would definitely recommended these guys. Thanks to my buddy Shaun for introducing me to them.
Nick was quick to schedule me in and have a look at the issue. When he arrived he was very clear about pricing and kept me informed throughout the process. He was able to figure out the obscure issue after a bunch of troubleshooting and I couldn't be happier! I would definitely contact this pro again in the future!
Nick was great, trouble shot the issue quickly and resolved faster than he predicted it to take!! Thumbs up and would rehire again!
