Gas Furnace Installation in Plymouth, MI 48170

“We first used Harriman when our previous furnace stopped functioning in cold weather in 2020. All the companies I contacted said they had no one to send for at least 24 to 48 hours. Harriman promised to send a technician within hours and they kept their word. We then used them for maintenance and eventually decided it was time to replace the old furnace. There are not enough words to describe the detailed level of service and installation of our new furnace from the point of purchase with Jon to completion of the installation. Jesse and Jeff were an amazing team of installers. They were very courteous and professional taking time to describe the process and answer all our questions. James was incredible solving a problem with the heat pump that was installed years ago by another company but would not function in the heating mode. James solved the problem and got it working. The office staff were always very friendly and responsive making sure we were kept informed of all schedules. It has truly been a great experience working with everyone at Harriman.”
