The objective is to increase your comfort level and reduce your energy expense. We provide installations for all types of heating and air conditioning equipment, plus geothermal systems, generators and hearth products. There is no substitute for the experience E. F. Laudenslager provides to all of our installations.

We were recognized by the State of Pennsylvania for over 100 years of continuous family business operation.

We Offer

  • Central air conditioning and heating
  • Ductless air conditioning and heat pump systems
  • Gas furnaces, boilers and water heaters
  • Tankless water heaters
  • Geothermal systems
  • Stand by generators
  • Gas stoves, fireplace inserts, logsets and space heaters
  • If you’re interested in supplemental heating with a cozy fireplace, stove, or log sets we can help. We install and service the best from Napoleon and Rinnai.

    Fireplaces, stoves or logs will add comfort and value to your home. Zone (supplemental) heating helps on those really cold days to assist your main heat source. Power sources – Wall furnaces such as Empire or Rinnai need electricity. Gas heaters, fireplaces, logs and stoves do not need electricity to operate and can run safely during a power outage.


    You can count on E. F. Laudenslager for a thorough repair that is done correctly by a qualified technician.

    For your benefit, we charge by the job, not by the hour. This way our technicians can tell you what needs to be fixed and the cost before the repair is performed. So you know exactly what needs to be done and you can then make an informed decision. Unlike other companies, you don’t have to worry about a big surprise when you get the bill at the end. And since we have a one year service warranty, you can be sure that we’ll do the job right the first time.


    At E. F. Laudenslager, we know that our good name only gets us in the door.

    We rely on a staff of qualified technicians who share our family's ideal that great service and honesty have kept us in business since 1894.
