Kelly's can provide and install just about any brand you may want. However our experience allows us to recommended some HVAC equipment over others.
There is often no reason to pay more for certain systems. They do not last any longer or provide benefits exceeding the higher cost.
Kelly's sells, services, maintains and installs: Day and Night, Carrier, ArcoAire, Rheem, Heil, Bryant, Tempstar, RUUD, York, American Standard, Trane, Goodman, Lennox and others!
Much has changed since your last system purchase! There are 2 stage furnaces, 2 stage compressors, variable speed blowers, modulating valves, seer ratings from 13-21. AND Lots of "bells and whistles" to choose from.
AND just a few manufacturers make most of the brands.
AND these manufacturers all use many of the same internal components.
AND each HVAC equipment manufacturers GUARANTEES are materially the same.
