I've had a contract with Comfort Central for several years to assess and maintain my HVAC system. This was my first visit with Jay, and he was courteous, came within the time frame planned, and did a great job. He found a problem with the pressure tank for my water heater, and explained how they go bad. He recommended a plumber, and the problem was fixed in days, likely preventing a failure and water leak which could have been very costly. Thanks!
