Tahiri Heating And Cooling is a Lowell HVAC outfit where the person who quotes the job is often the one who shows up to fix it. Across nine Thumbtack reviews from 2021 to 2024, the same story keeps repeating: a system fails, and someone is on-site within the hour. In a May 2024 review, a customer said Ahmed found and fixed an HVAC problem fast and didn't charge extra even though the call came in at 9pm on a long weekend. In an August 2023 review, a customer described Tahiri — named as the owner — arriving within two hours to diagnose a condenser frozen solid during a mid-July heat wave, measuring the unit and crawling into the subattic to trace the problem back to issues with the original installation. Earlier reviews, dating back to 2021, describe the same responsiveness: arrivals within 39 minutes to an hour, same-day repairs on weekends, and clear, upfront explanations of what was wrong. On Thumbtack it holds a 4.8-star average across 56 ratings, with 95% five-star; a small share, about 3%, are 1-star. It has been named a Thumbtack Top Pro in both 2021 and 2023. Thumbtack lists its work as covering AC repair and maintenance, heating system repair, thermostat installation and repair, and plumbing drain repair. For anything from a frozen condenser to a no-cool call, this is a company reviewers consistently say gets someone out fast and explains the fix before doing it — worth confirming up front whether it's Tahiri or another technician who'll be the one showing up.

Ahmed is very responsible, expert and quick. He found the issue of the HVAC system pretty fast and fixed it without charging extra even it was 9:00 pm on a long weekend Highly recommended
So thankful! Truly appreciate how professional, timely, and communicative Ahmed was. He came to the house in less than an hour and fixed the issue with my ac unit. He also identified something that would have given me trouble in the very near future and addressed it. Again, very thankful!
My HVAC system froze up during a mid July heat wave. I mean condenser coated with ice. Tahiri (the owner) came by within 2 hours to diagnose the problem. He carefully measured the condenser, air handler crawled in the subattic. He diagnosed several issues with the install but ultimately provided a fix to get back system back to normal. Very responsive and professional, and also timely. Will hire again.
He responded immediately, came the next morning, fixed our AC quickly and was upfront about what he was doing and the issues with our system. Highly recommended!
Tahiri is a really straightforward guy came the same day answered all my questions and did a great job I would definitely recommend him to others
