StillBills HVAC Mechanical Services

StillBills HVAC Mechanical Services operates from Greencastle, Pennsylvania, and has earned a 4.8-star rating across 24 verified customer reviews. The company maintains standard weekday hours with Saturday and Sunday availability, serving residential and light commercial clients throughout the surrounding region. Their service footprint includes Greencastle, Boonsboro, Chambersburg, Hagerstown, Shippensburg, Waynesboro, and nearby communities in both Pennsylvania and West Virginia.

The business distinguishes itself through specialized expertise in oil furnace systems, a niche that several competing contractors in the region do not service. Their service menu spans residential heating and cooling installation, repair, and preventive maintenance programs. The company handles both conventional split systems and heat pump configurations, providing customers with flexible options for year-round climate control.

Customer reviews consistently highlight rapid response times during emergency situations. One reviewer described a same-day arrival after their AC failed during warm weather, while another detailed how the team resolved a heating failure on the same contact. Technicians have handled heat pump diagnostics, gas valve replacements, and oil furnace repairs. Reviewers specifically mention Bill as the technician who responded to an urgent call when their system failed, arriving within an hour and remaining available for follow-up questions throughout the adjustment period.
