A simple tune-up of your heating and cooling system can result in the system running more efficiently to save you money on energy bills month after month.
Replace Filters on Schedule
By changing your air filter on a regular basis, you can prevent a dirty air filter from increasing energy costs by 5-15%. Most air filters should be replaced every 1-3 months depending on use and how much dust is in the air.
Seal Ductwork Leaks
Duct leaks: If 30% or more of the air conditioned air is lost before it reaches the rooms then all the energy that has been spent heating or cooling that air has been wasted. Severely leaky ducts can increase a heating bill by up to 30%. Sealing ducts with mastic sealant or metal tape is very effective.
Clean the Coils For
Efficient cooling requires clean coils. A clean evaporator coil and condenser coil can increase efficiency by up to 20%. Clean coils annually to maintain maximum efficiency.

Calibrate the Thermostat
An under-calibrated thermostat will continue to run when no longer needed. Simply adjusting the current one or replacing it with a new programmable thermostat can help to reduce these kinds of unnecessary running times.
Check Refrigerant Levels
Low refrigerant can force a system to run harder to cool. Annually checking refrigerant levels will help to ensure your system is properly charged to prevent efficiency loss.
