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.

Gas Furnace Maintenance in Westland, MI 48185

“You were recommended to us by Trane Company after another company tried to scam us into purchasing a new furnace. Mitch came out and took a look, was very pleasant and knowledgeable, and let us know that a new furnace was not needed at all, in fact, there was nothing wrong with ours. He spent a lot of time with us to make sure there was nothing going on with our furnace and explained everything in great detail. We are very appreciative that someone came out to take a look so quickly, and Harriman has become our new Heating & Air Conditioning company to call if needed. If something is needed, we would want Mitch to be the one who is sent out. We truly had a great experience and we are thankful we found a company that we can trust! Thank you all, especially Mitch.”

“The technicians arrived in a timely manner. John G and Junior where very professional and knowledgeable. They answered all my questions and shared a few tips and information that will be useful in the future. They where diligent in their work. They cleaned up and left the furnace and air conditioner, cleaner and working much better than how they found the units. I was impressed with how focused and considerate they where. It is not uncommon to get good service but to be fortunate to get the efficient and dedicated service that John and Junior demonstrated was exceptional. Thank you guys and I will be using you in the future. I will be passing on recommendations to others. Thank you for your hard work and knowledge.”

“Can not begin to express the great and professional, helpful, and prompt service I received from Josh when he came to do my annual Air Conditioning service last week!! Honestly he was such a pleasure, took time to completely answer any questions I had, explained them in terms I understood, and illustrated if I needed it. He gave me tips, and he is truly an asset for Harriman! He not only did the maintenance on the air conditioner (which was purchased from Harriman in 2019, but answered all questions I had about a previous installment of a new hot water heater!! I feel totally confident now on what to do. Kuddo’s and praises to him, he went over and above !! Thank you so much Josh, continue doing what you do, and your positive attitude!
