Ben Uscilla came out the morning after a 25-year-old furnace started giving trouble and spent more than an hour walking through repair against replacement before anything was signed. That December 2025 customer chose a new furnace and describes an easy-to-read contract and a deposit — the same unhurried start several other homeowners describe. Evergreen Heating and Cooling is Ben's owner-operated company in Hamden, Connecticut. A December 2024 reviewer notes that Evergreen is the name he now trades under, after running Highwood Mechanical LLC, and a May 2025 customer hiring him a second time says the crew stayed the same through the change. Anthony, Jake and Leia come up by name in the reviews, and the company holds a 5.0 rating across 26 Google ratings. Heat pumps are what customers describe most. An August 2026 homeowner had a new heat pump and ducted system put into a 100-year-old house; a July 2026 customer had a multi-zone install with completely new ductwork running both a ducted air handler and a ductless unit; and a March 2026 multifamily owner replaced old gas heaters with two ducted heat pumps after Ben explained the process in detail. The work covers boilers and air conditioning too: a May 2026 customer had an entire boiler and air conditioner system installed with the existing ductwork repaired along the way, and an April 2026 homeowner, referred by another contractor for an oil-fed boiler, got an immediate response and a competitive quote. He also turns up on other people's problems. In a November 2025 review a homeowner says Ben got the heat back on even though it was not his install; in a March 2025 review a customer says he sorted out a faulty mini-split another company had put in. In a February 2025 account a homeowner describes him asking about pets, allergies, children and whether the family likes the windows open before quoting anything. A strong call for a heat pump, a boiler, or a full system replacement where you want the owner designing it and a small crew doing the work. Ask which towns he covers from Hamden before booking, and get the equipment options in writing alongside the quote.
Ben and Anthony were extremely accommodating in fixing our air conditioning unit on a recent hot and humid August day! Would recommend Evergreen HVAC to anyone looking for competent and efficient service.
Ben and his team did a phenomenal job with the installation of a new heat pump and ducted system in our 100 year old home. He was extremely communicative and an excellent owner operator. He was fair, honest, and everyone on the team was the same way - from the crew to the office. We had an issue with cooling a few weeks after installation and Ben took the time to repair / diagnose the issue expeditiously, as well as ensure follow up that everything was going smoothly. We highly recommend Evergreen, they obviously take tremendous pride in their work and it shows.
I could not speak more highly of Evergreen Heating and Cooling. Ben and his team are absolutely top notch. I had heat pump installation with completely new duct work with a multi zone system running both a ducted air handler and a ductless unit. From the start of the process they made me feel confident in choosing them and I felt heard in the needs for my home. They made applying for permits and inspection seamless. Their communication both directly to the owner as well as his office staff was always friendly, accessible, efficient and effective. His team on site was extremely kind and professional and their work goes above and beyond. The attention to detail, tidiness and quality of work they performed in my home should be the industry standard. On top of this Their work has gained them being a diamond level installer for Mitsubishi products making their warranty best in class. I could not recommend this company more highly.
Evergreen Heating & Cooling is one of a kind. They are great people that do even better work. My hot water tank started leaking fast just weeks after closing on a new home. One quick call to these guys and they had it taken care of immediately and done with perfection. Evergreen is top notch and will be the only group I call for my home.
Ben and his team ( including Leia) were polite, professional, clean and efficient. Ben was quick to respond to my questions and kept us informed about installation time lines, etc. A company that takes pride in their work...hard to find these days. 5 stars!! *****
