At Harriman Heating & Air Conditioning, we know furnaces—gas and oil. Our heating, ventilation, and air conditioning (HVAC) team of professionals has been installing, repairing, and maintaining gas and oil furnaces here in the Farmington Hills area since 1996.

Our professionals always maintain the highest standards. Along with our prompt and courteous service, you will always be satisfied with a job well done.

Furnace Installation

At some point, all furnaces need replacing, even with consistent professional maintenance. Furnaces typically can last 15 to 20 years with regular maintenance. If you notice your furnace is no longer working efficiently or if it stops working all together, it is time to replace it.

When that time occurs, call our knowledgeable experts. We can be in and out with little inconvenience to you and your lifestyle. We make it our goal to work around your schedule, and we always leave your home in the same, or better, condition than we found it.

If you are currently looking for a new furnace, call and speak with someone on our team. We install all makes and models of furnaces, so we will be sure to find the perfect fit for your home, needs, and budget.

How Much Money Can a New Furnace Save You?

Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit's AFUE value and compare it to a newer, more efficient system. You can even customize it to better match your home's system for a more accurate calculation.

- Aaron H.

Gas Furnace Repair in Southfield, MI 48076

“The original technician who performed my routine maintenance had diagnosed a need for repair. My heat was going to be out for the night. After a call Harriman scheduled Mitch to come out the same day. Mitch was courteous and inquisitive. He heard a sound and upon investigation discovered that there was a just a bit of debris and there was no problem with the furnace! But Mitch did not stop there, he was curious about whether a nearby radon fan could be impacting airflow. Upon further investigation it was revealed that the air flow for my high efficiency furnace was being blocked outside. The other technician missed all of this. Thanks to Mitch I won’t have to spend my Christmas money on an unneeded furnace repair. Merry Christmas 😃”
