Just finished up a routine maintenance and tuneup on a American Standard gas furnace that we installed in 2016 in the Newcastle Delaware area. Had to replace a control board which was covered under warranty and also turn the blower speed up so I can get the temperature difference within limits. Other than that, the unit itself looked immaculate and needed a little love and care. Thank you so much to Dawn for longest in your home and trusting us with your comfort!
