PHS Mechanical says it has kept homes and businesses in Shelton, CT and New Haven County comfortable for over 35 years, with a small team led by its owner. One recent customer wanted air conditioning in the upstairs bedrooms of a house built in the 60's, without units hanging on the house or mini-split boxes in the rooms, and wrote that Pat came up with the solution and that it is nearly invisible and silent. When a recent customer's AC stopped working, PHS Mechanical was there the next day; that customer said the company also helped with furnace work over the winter. A 2025 customer said Pat and his guys handled a natural gas conversion quickly and neatly. A 2025 reviewer wrote that Pat and his team found and fixed the family's mini split after other companies couldn't. A 2024 customer said Pat and his crew installed a two-unit split zone a few years earlier, then arrived the day after one call to fix and recharge the unit. A 2023 customer described a central air/heat pump install and a repair to a hot water boiler at a fair price. A 2022 customer said Pat and his team replaced a 26-year-old gas furnace and central air conditioning system and answered their questions about the new equipment. A 2022 customer said brand new equipment failed within 6 months, that the owner was unwilling to discuss options and would not return to look at the problem, and that the matter would go to the State of CT department of consumer protection. It holds an active Connecticut S1 heating and cooling contractor licence, HTG.0403836-S1, under PHS Mechanical LLC.
The most beautiful thing you will never see. Pat and his team solved an AC installation problem that two other companies were at a loss to answer. I asked for retrofitted AC in upstairs bedrooms in a house built in the 60’s. I didn’t want units hanging on the house or mini- split boxes in the bedrooms. Pat came up with the solution. Not only is it nearly invisible, it is absolutely silent and installed in such a way that there are no drafts because of just a gentle moving and exhausting of the air. We’ve just had extreme heat in May and it is such a joy to use. Thank you!
My AC stopped working yesterday, and PHS Mechanical was here today already getting everything taken care of. He also helped me with some furnace work over the winter, and every experience has been excellent — great communication, reliable timing, thorough follow-up, and just genuinely great service all around. It’s hard to find people who are this dependable and professional these days, so I wanted to give credit where it’s due. Highly recommend!
Pat and his guys handled my natural gas conversion perfectly. They worked very quickly, neatly, and couldn't have been easier to deal with. My neighbor had used them previously and had the same experience
PHS Mechanical did a fantastic job when my families mini split decided to stop working. Pat and his team came through when other companies couldn't. They were professional, knowledgeable and took all the steps to find and fix the issue. Highly recommend 10/10.
I have used Pat and his crew for 10+ years. Pat is one of the most honest contractors I have had the pleasure of working with. Pat responds quickly, provides amazing service and is very fairly priced. I highly recommend Pat to anyone in need of HVAC services.
