What Our Clients Are Saying About Us
I would recommend KDM Home & Gas to anyone looking for great service at a good price.
July 10, 2020After our old (20+ years) unit gave out, I used HomeStars to obtain quotes for a replacement. Within 30 minutes of posting, I was speaking with Daniel, who was polite and helpful throughout the process. He offered a fair price and a few different products to choose from, and was able to do the installation the same week. I would recommend KDM Home & Gas to anyone looking for great service at a good price.
