Daniel was really great to work with. His communication and genuine care for the work being done made all the difference in the world to me especially as we’ve never had good experiences with contractors in the past.

Daniel showed up when he said he would, and took his time to explain to me what caused my humidifier to malfunction. His customer service skills are superior and his quality workmanship made the experience a pleasant one.

I would recommend KDM Home Gas to anyone looking for quality home repair services to their heating or cooling units.
