Crestside Ballwin Heating & Cooling

We just had a new furnace, AC and water heater installed by Crestside Heating and Cooling. We couldn’t be more satisfied with the price and workmanship. The sales and installation crew members were professional and kept us fully informed throughout the entire process.

Back in March, our 13-year-old furnace quit on a cold morning and there was a terrible smell coming from the vent. A serviceman came out that afternoon, found that the motor had failed, and one of the owners, Jeff Young, stopped by to help us choose a new furnace. Jeff was friendly, honest, and shared the company’s history — his dad started it, and now he and his sisters run it. You can really tell it’s a family business that cares about their customers. Fast forward to this past weekend — while getting new windows installed, the workers said they smelled gas. I called Spire, and they confirmed we had gas leaks and had to s
