Furnace and water heater installation
December 31, 2023
I understand the demand for service from a reputable contractor like HR Stewart however, I waited over a month without heat during an unseasonably cold weather streak before they were able to install the new furnace. I also don't think the team discussed any of my concerns regarding the placement of the new water heater with the estimator I spoke to. I needed room for my new softener and iron filter and asked that the new water heater be installed high enough for a brine tank to be installed under it and this was not relayed to the plumber who installed the new water heater. He installed it at a height that doesn't allow room for a brine tank. This was the reason I was going with a tankless water heater.

Well done HR Stewart!!!!
June 30, 2022
From initial quote to final installation, all that was done was extremely professional and courteous. Events required to push our installation up a full week which was 100% realized and done by HR Stewart (our AC went out completely and we were facing record breaking high temperatures). All work was done EXACTLY as proposed and we are in a home with an exceptional HVAC system. Well done HR Stewart and the installer who drove ALL of this, Eric Jacobs!!
