“I searched for a replacement draft inducer assembly with housing. Many places sold separate pieces/smaller kits. I liked the option offered on Shorty's HVAC. I ordered on a weekend, and patiently waited for it to arrive. Packaging was great, and product was as described/brand new. Swapping out was not too bad! My only suggestion is to offer FedEx shipping (in addition to current type) so that these quality parts can get to the site ASAP.”
