McCormick Heating & Cooling

Justin and the team at McCormick Heating & Cooling were excellent. They took the time to thoroughly diagnose issues with my boiler, test multiple valves, and walk through the system carefully to identify the most cost-effective solution rather than just recommending unnecessary replacements. Their approach was thoughtful, transparent, and very professional. Justin in particular was fantastic—knowledgeable, patient, and clearly experienced. He explained what he was doing at each step and made sure everything was working properly before finishing the job. In the end they replaced the necessary components and got the entire system running perfectly. It’s rare to find a company that is this honest, responsive, and detail-oriented. Highly recommend McCormick Heating & Cooling if you want quality work and technicians who genuinely care about doing the job right.

Have always had a great experience with Mccormick Heating and Cooling. Initially was referred to them by my home warranty company. They do my yearly preseason furnace checks. And most recently, David and Angelo and Justin were here to install a new furnace. Excellent communication from the office as well as the technicians prior to arrival. Professional on-site, explained the process well, left a very clean workspace when they were finished. Kudos to them for having to do all of this in a crawlspace!!
