I would recommend Karl and his team to anyone. They've replaced 2 furnaces and a swamp cooler for me, and have worked alongside me on a handful of other projects. They are always prompt, friendly, and professional. They produce good work at reasonable rates. I plan to have them back this fall to replace my boiler.

I've used KJ Thomas for the past 2 years now for services, minor repairs and most recently a furnace replacement. They've always been reliable, professional and on time, and took their time to explain what they were doing and why. I'm no HVAC expert but their work looks good quality as far as I can tell. I would recommend them.
