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.

“Rodney came out to do an inspection/estimate on some leaking furnace pipes.

He identified the problem right away and thoroughly explained how it could be fixed, answering any questions & concerns.

He also showed me how to adjust the humidifier, replace the humdifier filter and clear out the filter pump/filter tubes. Super helpful for a first time home owner.

PPE was worn as well as shoe covers and he cleared up any dust/drywall left over from the inspection.

And he was super nice to my dogs!

Thank you for a great first experience!”

Gas Furnace Installation in Ferndale, MI 48220

“Feel free to edit as needed. This review is for all interactions with Harriman personnel from initial service call to final installation.
John – Very impressed with how thorough this young man's inspection was and how quickly he was able to diagnose the issue. He was very polite and explained the situation thoroughly. I was glad that he uncovered the larger issues before I spent a lot of money on trying to repair a system that was truly at the end of its useful life. 27 years from a Trane XL80 is an excellent run, and it sold me on getting another Trane.
Jon – Very personable and easy to deal with. He made the purchasing decision easy, and the finance application was a snap to complete. We had an approval almost instantaneously. He set me up with a temporary furnace while my equipment was being sourced, and came back with (sorry, I don't remember who was helping that day — I want to say it was another John?) to install it. I was very happy with the speed and level of service.
Jay R. & Mike A. – I had Jay and Mike in my house for three different days, as my installation was a complete replacement of furnace, central air, air cleaner, air scrubber, and hot water tank. It also required some new ducting. These guys were very polite and respectful, always taking care to use masks (installation took place during the worst of the COVID pandemic), and they never had an idle moment — they were all business from arrival to departure each day. The new furnace is now oriented properly for easier servicing, and the entire installation was very tidy and of excellent workmanship. They also did a great job of cleaning up afterwards, and on the final day, I was given a guided tour on the different components of the new system. I have been very pleased with my experience with the Harriman company from start to finish, and I plan on having them out annually to help keep this system in tip-top shape.”
