I was looking to replace my rental tankless hot water system with an owned unit. I called a few reputable vendors and I found Marnie from Convertible Heating and Air Conditioning to be very knowledgeable, friendly, and fair. She knew the exact model I was renting and its specs, and was able to recommend a newer, more efficient model. It was super simple to communicate with Marnie and I didn’t feel any pressure at all when speaking with her. I was able to book an appointment on my preferred day, the techs came on time, they laid down a protective rug, and worked efficiently to replace the water heater. It’s been a week and everything’s going well. I have no hesitation recommending Convertible Heating and Air Conditioning to my family and friends.
