HVAC Services

E.F. Laudenslager’s objective is to increase your comfort level and reduce your energy expense. We provide installations for all types of heating and air conditioning equipment, ductless A/C & heat pump systems, tankless water heaters, gas stoves, fireplace inserts, plus geothermal systems, generators and hearth products. There is no substitute for the experience E. F. Laudenslager provides to all of our installations.

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.
