Brian did the fall maintenance on our furnace today. He was fast, tidy and very thorough. He even completed a CO inspection on the exhaust. Very pleased with his work.

The sales and service installation were top notch. I got a new Trane furnace/humidifier with a new thermostat and air conditioner along with a secondary air conditioner installed upstairs. The technicians did a clean installation and explained everything about the new system.

Bruce Bdinka · Google

We just got our new furnace and heat pump as well as our new water heater installed by Lancaster. The sales person with whom we were first in touch, Bryce, was very professional: he listened to us, he wasn't pushy, and he responded to all our many questions appropriately showing a good subject matter knowledge and very good people's skills. Then the installation of the excellent equipment that we chose was done in an outstanding manner. The technicians Wes and Andrew and their partners Austin, Matt, and Joe were very efficient, precise, proactive and courteous in the work they did. They discussed with us any adjustments to the original plans. The solutions to presenting issues they proposed were very well thought through; it was evident that they were highly knowledgeable about the work they were doing while they always kept our best interest and the respect of codes and regulations at the forefront. Thank you very much for this excellent piece of work, I am sure this will make our home so much more comfortable for years to come.

From start to finish, Lancaster was amazing to work with—from the first onsite with Kevin to the installation with his team. Kevin was available for all of our questions, and Matt, who took the lead during installation, was fantastic. The whole crew worked seamlessly together to install both the 15-ton and 20-ton units. They took the time to address all of our issues and concerns, and came up with a great working plan to ensure both of our facilities will be well taken care of. We would highly recommend Lancaster to anyone looking for a team that goes above and beyond.

Our air conditioner died in the middle of a heat wave. We called Lancaster and were told they could have a service tech out that same day. And as promised, the tech... Jason... showed up within a few hours. Since the unit was fairly old, we thought it might be beyond repair and that we might need to buy a new one. But he quickly diagnosed the problem as a faulty part, which he replaced. We were back up and cooling in no time. Very impressed with the quick service and friendly, knowledgeable service tech. Would highly recommend.

They listened to my circumstances and covered a part under warranty. I appreciate how helpful they have been and how quickly a technician came out to take care of my furnace.
