The Importance of Regular Maintenance

Lack of maintenance is number one reason why systems break. Having a licensed contractor perform regular maintenance on your system is the best defense against unexpected breakdowns and expensive repair bills.

Do I Really Need Maintenance?

The short answer is YES. Every heating and cooling system benefits from annual maintenance. Professional, regular service by Energy Stars Heating & Cooling Co ensures your equipment runs at maximum efficiency. Our technicians don’t stop there. We perform necessary cleaning, checking, and find problems before they lead to more expensive breakdowns.

Maintenance Membership Benefits

Our maintenance service plan is simple. There are no hidden costs or unnecessary inspections. We give you peace of mind that your system is in good shape, energy efficiency, and safe.

Lower Energy Bills

Your system might be running, but it might not be running at peak efficiency. A neglected system loses capacity to keep your home comfortable. If your unit has to work harder to give you the same results, expect higher energy bills. Unless you call Energy Stars Heating & Cooling Co. Our regular maintenance helps your equipment running the peak efficiency.

Lower chance of a catastrophic breakdown

Everyone wants a breakdown free heating and cooling system. Having your system break down in the burning hot summer is miserable. No heat in the winter is dangerous. Our maintenance plan greatly diminishes the chance of breakdown.

Longer equipment life

Air conditioners, furnaces and heat pumps function best when they’re regularly serviced and cleaned. One bad part can cause a domino effect that causes the entire system to break down. By following the manufacturer's instructions on maintenance, you can add years of life to your system.

Fewer Repairs

With regular maintenance, our technicians can spot minor problems before they become major issues. Our regular maintenance catches common issues. Do you hear a strange sound or notice funny odors coming from your furnace? While many homeowners have these problems, it doesn’t mean you should have to live with them. Let us contain the small problems during our maintenance to keep your home comfortable.. By preventing future repairs, annual maintenance pays for itself.

Safer equipment operation

A neglected HVAC system is not only more expensive to operate, but it can put your family in danger. For example, if a furnace develops a crack, carbon monoxide gas can escape and leak into the home. An electric HVAC system can short circuit and can create a fire hazard. Our maintenance plan includes safety checks on all equipment to find dangerous issues.
