HVAC Industry: Who wins with High Warranties?

Posted on August 3, 2015 at 10:26am 4 Comments

During the sales process, it is inevitable warranty periods will be raised.  I remember raving about how the latest and greatest HVAC product led the industry with the longest warranty period.  Very often this only lasted a short period of time as other Manufacturer’s would continue to match warranties with their line.  Things often got out of hand as warranties have reached ‘limited lifetime’ on parts like compressors or heat…

Should this Duct Layout be Banned?

Posted on September 3, 2014 at 6:24pm 3 Comments

When is it ok to put your ducts into an attic, tight up against the Roof Deck?  With more conventional building techniques, I would have to argue: NEVER!  I do not care how the homeonwer pleads to keep their storage space, you cannot count on delivering cool air to the conditioned space with said branch duct.  Even if you did figure out a way to secure the duct to the peak without crushing the inside diameter, the CFM is not the problem.  The real issue becomes the dry bulb temperature of…
