Top-Rated HVAC, Plumbing & Electrical Services in Lancaster, PA

Gabe Hagy was out to my house to fix my plumbing. Haller is the Best experience I’ve ever had in a company. The techs are so well trained and honorable, and fixed any issues my heating, cooling, plumbing or electrical my old house has thrown at me over the years. Maybe if every company was as good as Haller, just maybe we’d be able to achieve world peace.

My experience with Haller since they installed our heating and cooling unit 5 years ago has been excellent. They keep in touch with us to make sure everything is okay and when we had our unit serviced this the technician (Ken K.) was fast, efficient, friendly and more than willing to answer any questions we had. We have been very pleased.

We had general maintenance done on our furnace and the technician was very professional. He used shoe covers and completed the service in a timely manner. He let us know what services he was doing which was also appreciated. I would highly recommend Haller for all of your HVAC needs.

I had a technician, Ron Losch, come out to service my HVAC system under warranty, and I couldn't be more impressed. Not only did he handle the HVAC inspection with total professionalism, but he also took the time to recommend an air scrubber to help with airborne contaminants—something I really appreciate for my home's air quality.
While he was here, he proactively checked my water heater expansion tank and discovered it had deteriorated. He was able to replace it on the spot, likely saving me from a major headache (and flood) down the road. To top it all off, he noticed some messy Pex plumbing and volunteered to clean it up with cable ties just to make sure everything looked neat and professional.
Ron is friendly, knowledgeable, and incredibly thorough. 5+ stars! I highly recommend their services to anyone looking for quality work.
