I'm happy with what they did.

— William from Warsaw

Absolutely wonderful, professional and courteous service!

— Amanda from Leesburg

Needed a new thermostat for our electric baseboard heat. Joey did a great job diagnosing and installing a new one. Thanks!

— Anna from Warsaw

I recently had a gas insert put into my fireplace. From day one completely through installation, things were done professionally and timely. They made two trips to my house. Each time the person showed up on time, answered all my questions, etc. Installation was completed quickly and hassle-free. He probably ly left things cleaner than what they were when he got here. Most importantly the fire looks great. Very happy with the entire experience.
