Ask us about our Preventative Maintenance Plans

“Why Get Preventative Maintenance Done? My unit is fine.” Many customers ask this question. Your unit is a machine like any other. Tune ups are needed from time to time to ensure the best performance, and make sure everything works as it should. There are benefits beyond just peace of mind.

Improved air quality
Furnaces with dirty filters can harbor dust, dirt, and even mold. Keeping these clean and in good condition improves air quality, and is especially important to those with asthma or allergies.

Lengthen the life of your unit
Failing to take care of your unit means it won't last as long. Just like a car with no tune ups will wear out faster, so will your heater. Let us help you get the most out of yours.

Increased efficiency and cost savings
Units that aren't maintained are inefficient and can run 20% harder. This difference shows up on your electric bill, as well as more frequent malfunctions. Preventative maintenance can help avoid high electric bills, as well as costly surprise repairs.

What Do Preventative Maintenance Plans Include?
Our highly trained technicians will come and perform an in depth 22 point tune up on your system. The process is hassle free, usually takes less than an hour per unit, and is always performed with the utmost care. You also get the following exclusive benefits.

Preferred customer same day scheduling
No matter how full our schedule is, as a preferred customer you will always get same day service for service calls.

15% off all parts and labor
Enjoy a 15% discount year round off any service call, and 15% off all parts and labor.

24 hour emergency service - with no overtime charges
Why pay time and a half overtime rates if you need us when you could pay 15% less than our regular rate? Days, nights, or weekends, this will always be available to you as a preferred customer.

Bi-Annual System Tune Up
In Spring and in Fall we will provide you a courtesy call and email letting you know it’s time for your seasonal tune up. This tune up makes sure your system is operational, and ensures it is prepared for the upcoming seasonal change. In addition, we can often find potential problems when they are small and easy to fix. These tune ups are at no cost to you!
