KC Mechanical, LLC is an HVAC company. On the Better Business Bureau, the company says it offers boiler repairs, air conditioning services and ventilation services. A 2024 Google customer whose boiler was locked out after running out of oil said they explained the problem in less than 5 minutes and found a resolution over the phone, and that the company could have just scheduled a service call instead. Another 2024 Google customer, whose unit was down during an intense heat wave, said the company took the call immediately, promised to come out early the next day and fixed the unit that day. That 2024 customer also said the tech worked with the mall maintenance team to locate the unit on the roof. A 2018 Google customer said a furnace issue left them with no air conditioning during 90+ heat, and that the company called back quickly and squeezed them into its schedule to fix the problem. A 2018 Google customer said they had used KC Mechanical for 20 years for maintenance, and then for the purchase and installation of a new furnace. Its Massachusetts HVAC licence, number 340-SM-B, held by Kc Mechanical LLC, is expired on the state registry.
Excellent knowledgable service, prompt and trusted for years. I wouldn’t put my home or business HVAC needs in any other hands. John & Jim for the Win!
I called KC Mechanical concerning my boiler being locked out after running out of oil. I had tried all the tricks of bleeding the line, etc but couldn't get it to fire properly after refilling the tank. In less than 5 minutes, I was able to explain my problem and find a resolution, over the phone. I've heard countless horror stories of "Big HVAC" taking advantage of their customers. They COULD HAVE not helped and just scheduled a service call instead, but today, HONESTY prevailed. A breath of fresh air, especially around the holidays as it is. Thank you KC Mechanical!
Highly recommend this company. I was recommended to this company by my landlord. I called this company after calling over 70 Hvac companies in the area hoping to get anyone to help me service my unit which was down during an intense heat wave. They immediately took my call and promised they would get out to me early the next day. Sure enough they were true to their word and fixed my unit that day. The tech had difficulty finding my unit on the roof that houses many other businesses units and he worked with the mall maintenance team to locate my unit. He communicated with my employees and keep us in the loop which was very professional of him. Will definitely use this company again in the future for HVAC service.
I have used their service for years!
