"Our incident happened on a Sunday and Chris was super professional, responding to our questions in a timely manner. He explained everything and gave an estimated cost right away. The repair was finished within one day and done competently. Highly recommend for gas line installation and repair as well as HVAC."
"Chris was down-to-earth, exceptionally knowledgeable, and always willing to answer any questions. Their prices were competitive and the work looked great when completed. My experience overall was amazing — I recommend them without hesitation."
"Chris was very helpful when our AC decided to stop working. He talked me through some troubleshooting over the phone, then followed up to make sure those tips worked — and they did! Super friendly and knowledgeable."
"Used this company a few times for my rental properties in London. Easy to get a hold of and always has availability for short notice jobs. I've never placed a callback service call as the job was done right the first time."
"Middlesex Mechanical did an outstanding job — quick, efficient, competitive, and very professional from start to finish. Their attention to detail truly showed. My wife has been swimming almost every day since. Truly the best investment we've made for our lifestyle."
"Chris and his team have been servicing my properties for almost a decade. Honest, reliable, and quick with itemized billing. No hidden fees. They offer solutions other companies won't. This is the only partner you'll need for heating and cooling."
"Very informative, friendly, and knowledgeable. They walked through the process of replacing the hot water tank, AC, and furnace, and answered all my questions. A great experience from start to finish. Highly recommend."
"Five stars is not enough for Chris — he's on time, responsive, and does his work very quickly and efficiently. Middlesex Mechanical is the place to go if you need a new air conditioner or furnace replacement. Well recommended."
"Chris and his staff came to the rescue when our very old furnace died on the coldest week in January. They came over right away and replaced it the very next morning — rearranging his schedule when other companies said it would be at least another week. The new furnace has made a big difference in warmth and utility costs."
"Amazing company! Very honest, fair, and super communicative. Thank you!"
"Chris installed a new furnace and AC unit in my townhouse. He was thorough in explaining the products and didn't try to up-sell in any way. The job was done in a day and both units look great. I highly recommend Middlesex Mechanical for your HVAC needs."
