What Customers in Lancaster Are Saying

“From the initial call for water pressure issues, to the final clean-up after installing our new water softener, it was a delight to work with Haldeman Mechanical. The serviceman was professional, knowledgeable and wore a mask while he was in our home (we did, too, while we interacted with him). Ken explained the problem to us and the remedy, and installed the softener neatly in the next visit. We are VERY satisfied with Haldeman Mechanical.” – Deb Bendit (Google review)

“I have been using Haldeman Mechanical for a number of years and I have been very happy with their services. The repairmen arrive on time and do a fabulous job, over and above what I have previously experienced. Please give them your business….You won’t be sorry!” – Debbie Cornelius (Google review)
