At Harriman Heating & Air Conditioning, we recommend regular maintenance on your heating, ventilation, and air conditioning (HVAC) system to ensure its high efficiency and long life span. Our heating and cooling professionals are highly trained and experienced to perform maintenance on your units. No matter what your HVAC maintenance needs are, Harriman Heating & Air Conditioning is here for you.

What Does Maintenance Mean?

The term maintenance refers to preventative care you take on a regular basis with your HVAC system. The professional actions performed as part of maintenance, such as tune-ups and inspections, assist your system in running at its peak performance from day to day and extend its life.

What Is Involved in Maintenance?

At Harriman Heating & Air Conditioning, we strongly recommend regular maintenance on your system. Just like any system or unit you own, it needs routine care. You would never simply drive your car for years on end without changing the oil or rotating the tires. The same principle applies to your home’s heating and cooling system. Your system requires consistent, proper attention known as maintenance.

We suggest scheduling one of our highly trained professionals to perform preventative maintenance on your system at least once a year. The best schedule is to have one of our experts perform maintenance on your heater in the fall before you begin using it once the temperatures drop. We recommend the same for your cooler, having maintenance in the spring before its first use when the mercury starts to rise on the thermometer outdoors.

During a maintenance visit, our specially trained experts will clean and check your system. This involves checking all its parts to be sure they are in top condition and performing efficiently. Any parts showing wear and tear will be noted and discussed with you for an appropriate time for replacements.

All components of your system will be cleaned and your filter will be replaced. Your filter plays an important role in your home’s indoor air quality as well as promoting your system’s high efficiency.

We recommend changing your filter every three months or more, depending on factors in your home such as chronic illnesses, pets, and smoking. Your heating and cooling system cannot work as it is intended to work without excellent airflow, which your filter can either support or impede.

Regular maintenance keeps your system’s energy efficiency high, so you are not paying extra for energy costs. Maintenance also prevents unexpected, costly repairs and extends your heating and cooling system’s life.

We feel so strongly about regular HVAC preventative maintenance, we offer various maintenance plans. Our plans take the effort out of maintenance for you, ensuring your Novi area home’s heating and cooling system receives its needed maintenance. We designed several levels to meet the service and financial needs of all. Call us today to discuss the best plan for you.

“Omigosh! Mitch was AH-Maze-Ing!

He was very friendly and handed me his card outside the front door to verify that he was from Harriman.

He thoroughly checked my furnace and changed my filter and then took a look at my other filter (that minimizes dust in my home) and advised me when to change that. He then showed me and helped to clean some of the pipes that were picking up bacteria and showed me what to do to in order to help keep it clean. He also explained some other maintenance features and in my opinion gave me a great refresher course in my furnace since it was installed about a year ago. I then stepped away and let him do his other standard maintenance work on the furnace. As I don’t know all the specifics – he seemed to do a great job.

He then recommended me getting a new water heater (admittedly, mine is pretty old) and told me what to look for as it ages to make an informed decision about when to pull the plug on getting a new one and recommended the maintenance program to show me how to get discounts and speedy service if needed. Seriously – He was excellent. Ever since I signed up with Harriman, I’ve been nothing but pleased. Kudos to you and your team and making such great hires! I am certainly a pleased customer! :-)”
