Just as a tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort.
Keep your cooling and heating system at peak performance by having a contractor do annual pre-season tune-up. Contractors get busy once summer and winter come, so it's best to check the cooling system in the spring and the heating system in the fall. To remember, you might plan the tune-up around the time changes in the spring and fall.
The REMC's HVAC tune-up rebate is designed for air source heat pumps and central air conditioning systems. Gas furnaces are not eligible unless part of a central air system.
Something that you can do yourself is to inspect, clean, or change air filters once a month. This will also help maintain your system in between tune-ups. A dirty filter can increase energy costs and damage your equipment, leading to early failure.
