The heat exchanger on my furnace failed in the middle of winter. Andrew was quick to respond and was even able to rearrange his other appointments to get a new furnace installed ASAP. They were candid and very professional, and were happy to answer any questions I had. I definitely recommend giving them a call!

I had County Lines HVAC do a gas fireplace pilot replacement. They replaced the pilot and cleaned everything inside and out. Everything was done quickly and professionally. The fireplace looks amazing. The two men who worked on the fireplace were very friendly and kind. The price was fair, too. Will definitely call them again.

We wanted to replace our fireplace, and we had been told previously, that it would be a very challenging job. I located County Lines through Google, and after reading all the excellent reviews, I decided to give them a call. After meeting with Andrew and discussing our options, we felt very confident that Andrew was the installer we wanted to do the job. Andrew made what could have been a very stressful experience a very enjoyable one. He is very friendly, knowledgeable and accommodating. We are both extremely pleased with how the fireplace installation turned out. The fireplace is beautiful! We will go to Andrew for any future needs we may have.

We hired Andrew and his team from County Lines to complete a retrofit of an old 2003 era gas fireplace, along with a new HRV system. We purchased the CX36 model fireplace and it is absolutely beautiful!! The HRV has removed any traces of moisture on our windows when it's extremely cold outside. Andrew and Jeff were both professional and provided tips and ideas to finish the hearth frame on which the fireplace sits and educated us on the systems installed. Highly recommended and will be using their County Lines services again.
