Real reviews from real customers across Greater Pittsburgh.
"I called to have my water hot tank replaced because it was leaking. The team at Keller heating and cooling had the job done in a few hours with new lines and fittings as well. There was no mess left behind and they hauled the old tank away."
"Our heat went out this week, which is always stressful during these cold days. We called Keller Heating and Cooling, and they sent someone out right away. Thankfully, the issue turned out to be a common part that needed replaced. Responsive, knowledgeable, and quick!"
"This is the 3rd or 4th time I have used Zach and his crew over the last couple years. They are always quick to respond/arriver and get things figured out and fixed. Fair pricing and always professional."
"Very professional and knowledgeable crew! Zach and his team are very transparent and take the time to educate their clients on whatever system they may have. The two guys he sent out were amazing."
"Will not use another heating and cooling company. Mr. Keller and his crew came out and installed my new furnace in a day, after talking to him just a few days prior. Very professional and neat."
"Zack has done several furnaces for us now. I'm always amazed how fast he can get me an estimate and the turnaround time for a start date is incredible. He has taken care of us in emergency situations and has always given a super fair price."
