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.

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.

“John G. is a stud! This man rolls up with just a rough idea of what we were dealing with (based on my best non-professional description) and was able to diagnose the problem with my furnace quickly AND ACCURATELY.

Beyond that he provided a level of transparency, knowledge, and clarity that left me with a level of trust I did not get from some of Harriman's competitors. I highly recommend Harriman generally, and John G. specifically.”
