We have been with Interstate Heating and Air since 2007 at which time they installed a new Carrier unit alongside an existing (Rudd second unit. Interstate services both units twice a year and the techs have always been professional, knowledgeable, and friendly. We recently had our 30-year Rudd unit replaced with a new Carrier and we could not be happier with the whole experience. If you need information about anything, Interstate is always courteous and prompt in addressing any question.
I would recommend Interstate to anyone looking for a top-notch company who puts the interest of their customers first. They are highly regarded and show the utmost integrity.
