Five Stars HVAC Services is a Westborough HVAC contractor with two detailed Google reviews, both negative. The dated accounts describe furnace and attic-unit work, including a 2022 furnace installation that a homeowner said never worked properly and a later report of flooding after a pipe burst. In a November 2025 review, a customer said the team was difficult to schedule, left ceiling and wall repairs unfinished, and took weeks to address a leak attributed to an attic unit. Another review, dated January 2024, described repeated furnace problems, a burst pipe that flooded an in-law apartment, and difficulty getting the company to investigate or resolve the issue. Google shows 2.7 stars from three ratings. If you contact the company, ask exactly who will perform the work, what follow-up and warranty obligations are written into the estimate, and how any water damage or finishing work will be handled. The available written accounts make documented scope and post-installation support especially important to confirm before booking.
Anderson was nice and the prices were competitive but when it came to finishing the job, showing up regularly and when scheduled, he and his team failed. I would not recommend them even at their price because of the lack of follow through. One unit they installed in the attic caused a leak which discolored our ceiling. He had it repaired after several weeks of delay due to workers being "sick" and the weather being rainy but his team who were unreliable and often inexperienced did not repaint the ceiling as promised. They also left a hole in the in the ceiling and a he in our wall where they had to uninstall a thermostat. I have given him several weeks to fix these issues and he has still not sent his team. I'd recommend you pay more for a reliable and experienced group who knows how to follow-up and finish a scheduled job.
Worst company and people to work with! Very inexperienced owner and employees. They installed a new furnace in my in law apartment December 2022 and the new furnace never worked properly. My family and I traveled and a friend saw that a pipe burst flooding the whole apartment. We lost our home insurance because of a damage of more than $100,000 to fix. When we contact the company they never came to look. On the next year October 2023 when we turned the machine on it didn’t work, again tried contacting the company, they came about 2 times and didn’t know what was wrong, João kept saying that the whole house was wrong except fixing the machine. Machine worked for a week and stopped again. Then owner travelled and machine still wasn’t working it kept blowing cold air. Tried to resolve with owner (João) to come fix machine but he never got back to me. So we had to find an experienced company, the company came said condensate trap was installed wrong and emergency precious switch needed to be for propane, and combustion was incorrect and needed to be cleaned. After they cleaned, they saw the heat exchange was broken. We had to use the warranty on a 1 year old machine that never worked because the owner is inexperienced! And after the heat exchange was installed they noticed the kit was an universal kit used and they had to put one for a propane machine. Then they said the pipes outside are too close to each other causing cross contamination. At the end, we spent $5,008.75 to fix a BIG mistake and a lot of damage Five Star caused to us, and lost our insurance company. WORST COMPANY AND OWNER HARD TO DEAL WITH!
