Hear What Our Customers Have To Say
“Very pleased with everyone at Lancaster Heating and Cooling. Our experience started out with the outstanding knowledge and exceptional customer service from the sale rep Cassandra Muir and continued with the prompt clean & efficient installation crew!!! Thank you all very much for everything. I would highly recommend everyone to call Lancaster for all your heating and cooling needs we know we will!!” – Charlie Puma, Google, July 2025
“I highly recommend Lancaster for purchasing a furnace and an air-conditioner. They installed a furnace for me a couple of years ago. At that time I had several quotes from different companies to compare. The Lancaster sales rep, Cassandra, is very knowledgeable, professional, and provided the best price of all the companies, without having to haggle back-and-forth. She clearly and concisely explained the pros and cons of the options that are available and helped me to pick the best choice for my situation.
This year, when I needed a new air-conditioner, I knew that I wanted to go back to Lancaster. I could not be more pleased with the service. The installers are great! …. knowledgeable, meticulous, professional, tidy and friendly.
I HIGHLY recommend this company!” – Diana Jordison, Google, June 2025
