HVAC Service FAQs

  • How often should I schedule heating and air service?

    The Witmer Company recommends scheduling professional heating and air service twice a year—once in the spring for your air conditioner and once in the fall for your heating system. This routine care ensures efficiency, prevents breakdowns, and extends equipment life. Call 717-229-0741 to schedule seasonal service in the Lancaster Area.

  • What are common signs I need HVAC repair?

    Uneven temperatures, unusual noises, rising energy bills, or frequent system cycling often indicate a problem. If you notice these issues, contact The Witmer Company right away. We provide 24/7 heating and air service in the Lancaster Area—call 717-229-0741 anytime.

  • Is it better to repair or replace my heating and cooling system?

    A heat pump and an air conditioner use similar technology, but a heat pump can be reversed so that it carries heat from outside (even if it’s very cold, there’s still some heat in the air) into your home for gentle winter warmth. Heat pumps are also used for ductless systems, by running refrigerant lines from the external unit to the internal unit or units instead of having it all in one outside with the air passing through a duct.

  • Do you provide emergency heating and air service?

    Yes. The Witmer Company is available 24/7 for emergency heating and air repairs. You’ll always reach a live operator, never a machine, when you call us at 717-229-0741 for urgent service.
