Hear What Our Customers Have To Say
“This is the second time I have had Lancaster Heating and Cooling install an HVAC item. This time it was a split system. The guys were fantastic and did a great job. Couldn’t ask for a better team. Thank you.” – Jen, Google, October 2024
“We recently had our furnace, AC and hot water heater replaced by the team from Lancaster. I use the word team deliberately, as they worked as a team. From our initial contact with Cassandra to the install group of Pat, Ben and Austin. The installers worked quickly, efficiently and cleanly over the two days it took to remove the old systems and install the new ones. A minor issue was dealt with a couple of days later by Rob. While we were at it, we decided to have the ducts cleaned as well. Would happily recommend this company after this experience.” – Rod Crombie, Google, August 2024
“The team at Lancaster took care of our new furnace, and the service was outstanding. Great job!” – Bryan, Google, March 2025
