"Called FH HVAC in Knoxville, IL on a Saturday with a broken AC in summer weather.

Genuinely the best HVAC service call I've had in years of homeownership."
"We run a small retail shop in Knoxville, IL and our HVAC went down on a Tuesday during a sale event.

Five stars, no question."

That avoided what would have been an emergency call in August when it finally failed — and August emergency rates are not fun.
