What Our Clients Are Saying About Us
I would like to recommend your company to anyoneSeptember 10, 2020
Your company KDM Home & Gas has just installed the CV 50 water heater to my house. The installation process was so smooth. You guys put on the carpet runner in order to avoid any scratch and damage to the carpet and the floor. Your professional guidance has highlighted the B Vent should be installed for the chimney exhaust in order to comply with the building & safety code. You have even performed leak test & dial test in order to make sure the whole installation is in a perfect manner. The registration of the warranty is also very convenient and easy.
I really appreciated that you came to my house to inspect the situation and provide the quotation to me before we decide to get the new water heater. The whole process was so smooth and communicate very well. You return all my text message on the same day basis or even within short time. I would like to recommend your company to anyone.

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.

After 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.
