Without regular maintenance, your AC could be working twice as hard during the summer months, which means higher energy bills. Not to mention that a lack of proper maintenance can cause a breakdown during the peak of a summer heatwave. We’d rather help you prevent a costly repair than have to help you out on an emergency call.

Although it is very important to have a professional provide the services for the Spring central air conditioning tune-up or heat pump Fall service, there are still things you can do to make sure that it stays in good working order between service calls. Basic maintenance includes:

  • Changing your air filter out every month (or less depending on your manufacturer) year-round.
  • Keeping the drain outside the house clear of grass, dirt and other obstructions.
  • Keeping all vents clear of obstructions such as furniture, especially the return air vents.
  • Keep your thermostat easily accessible and clear of lamps and other heat sources that could fool the system into thinking your home is warmer than it is.
  • You can extend the life of your AC unit by following these suggestions and staying up-to-date with your MD Air Conditioning Maintenance Plan.
