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.

When your furnace begins to make a strange noise or if it only blows cool air, it is time to call in our HVAC professionals. Our highly trained team members will promptly come out to your Michigan home to quickly diagnose and repair the issue.

Since we service and install a wide variety of furnace makes and models, we will get right to work, since we know precisely what needs to be done.

Furnace Maintenance

Proper maintenance can extend the life span of your gas or oil furnace and keep it in good working order along the way, saving you money. That is why we offer preventative maintenance programs for your heating and cooling system.

Our expert team will schedule a preventative maintenance program customized just for you and your needs. With regular maintenance, you can expect an inspection and cleaning of your furnace and its components. This helps you achieve the energy savings your efficient furnace can offer, saving you money year after year.

Regular maintenance is also a good investment. During our maintenance visits to your home, our professionals can spot a needed repair before it turns into unexpected and costly trouble for you. We will head it off, keeping your life running smoothly.

Gas Furnace Replacement in Farmington Hills, MI 48335

“I could not be happier with the service I receive from Harriman. This is the third time I have used this company and I am never disappointed. This time my old furnace was not able to be repaired but John H. and Robert, with masks and foot coverings, helped me choose a product that suited my needs and budget. The next day Jesse and Jeff arrived, also masked and with foot coverings, polite, professional and so hard working, and installed my new furnace. I was so happy to see Jesse since he installed my water heater and the city inspector commented on what a great job he did. I know that I am always going to have polite, professional people with Harriman and that the job will be done correctly and to code the first time. I would recommend them without reservation.”

Gas Furnace Repair in Farmington Hills, MI 48336

“Steve was great! He is very personable and engaging. He cleaned up and took any debris created by the repair with him. He did need to return the next day because he needed another part. We had to go out of town but Steve and the dispatcher managed to fit us into the schedule so that our furnace could be repaired and we could still leave on time. Thanks, Steve!”
