Maintaining Any A/C System

When the temperatures climb toward 90 degrees or above, a quality air conditioner makes life much more comfortable. To make sure your air conditioning unit is ready to cope with extreme summer temperatures, it is a good idea to have some preventative maintenance done before the cooling season starts, as well as after the cooling season ends. At The Witmer Company, we can make sure your A/C unit is performing properly and efficiently with our comprehensive air conditioner maintenance service.


Since 1941, we have served both residential and commercial clients throughout the Lancaster area, providing HVAC repair and HVAC maintenance services that have earned us a reputation for quality and reliability.

Why Maintenance of Your A/C System is Crucial

Routine air conditioner maintenance helps to keep your system in peak condition, operating both efficiently and effectively to keep you comfortable through the hottest summer days. Some benefits of preventative maintenance include:


  • Lower energy costs: With regular cleaning, lubrication, and air filter changes, your A/C unit will not have to work as hard, reducing energy usage and cooling costs.
  • Reduced repair costs: With regular inspections and maintenance, potential problems can be caught early, before they cause further system damage and expensive repairs.
  • Extended lifespan: By preventing unnecessary system damage and repairs, your air conditioning unit will last longer than poorly maintained systems.
  • Warranty protection: By following the manufacturer’s recommended maintenance procedures, you will make sure your system remains protected by any remaining warranty.


At The Witmer Company, our professional technicians have the knowledge and experience necessary to handle all your HVAC maintenance and repair needs. For more information about the advantages of regular A/C maintenance, contact our team today!

  • Checking the condenser, evaporator, and refrigerant lines for leaks
  • Changing the air filter
  • Cleaning the air handler
  • Inspecting the plenum and ductwork for air leaks
