Preventive Maintenance Contracts A quality pre-season inspection of your heating and cooling equipment provides many benefits. Equipment life is extended, operating costs go down, comfort levels go up, costly emergency repairs can be avoided, and potential hazardous conditions can be detected early. Safety, comfort, and energy savings are great reasons to sign up for your fall furnace inspection. With a maintenance contract you always receive priority service, never pay a service call fee, receive discounted labor rates, enjoy a one-year warranty on all repairs, and if an emergency occurs after hours you are not charged overtime rates. It’s a quick, easy process. Print and send in your Maintenance Contract What do our Customers Say About Us?

FAQ's Q: Is having a carbon monoxide test performed on my furnace really important? A: Yes. This simple test has two important benefits – one is safety and the other is that it provides important diagnostic information about the condition of your furnace. I recommend having a carbon monoxide test performed every fall. High levels of carbon monoxide at start up indicate service related issues. If levels are over 100 parts per million (P.P.M.) this would be a indication of more serious issues that need to be resolved. Levels even higher signal other serious issues with the furnace. Let us give your furnace a carbon monoxide check-up – enjoy peace of mind and increased furnace efficiency.
