“Horsetooth Heating and Air was super professional and quick when our heater fan went out last winter. Kyle got it back up and running quickly and was very thoughtful in terms of keeping it within our budget and not talking us into anything we didn’t need. We’ve had him back to keep our AC running well. Highly recommend!”
