Sitler and Lemmon has been servicing the Lawrence, Beaver, Butler counties and surrounding area since 1957. 

We service most brands of furnaces and a/c units. We also offer yearly maintenance agreements in which we provide service twice a year (spring service to the a/c unit and fall service to the furnace), plus a 10% parts discount. This is scheduled at your convenience and will keep your equipment running at peak efficiency with fewer breakdowns.

When the time comes to replace your unit, we can offer you many options to fit your budget. Our expert installers are friendly, neat, and clean, and provide quality installation every time.  All residential furnaces come with a 10 year parts warranty, and remember, estimates are free of charge!

Upon completion we will walk you through your system and thermostat to get you started.  Below is a list of system types and manufactures that we represent:
