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.

I had reached out to County Lines about an issue with the HVAC unit in a house I had just purchased. They advised that they were booked up for a couple of weeks, but then found an opening early one AM. They showed up on time, fixed my problem and we very accommodating when it came to the billing for their time. I would highly recommend these guys anyone looking for HRV service and support. A+ in my books. Thanks again fellas!
