All these bills must be paid. Many low priced online suppliers have no idea what their operating costs are. They've never taken a business course and they live from sale to sale. As a result, many may go out of business. The difference between our prices and the lowest priced online hvac store has to be coming from someplace.
Chances are it's coming from the support staff.
Low priced hvac sites pay their support staff less then we do, if they have support staff. They have to, their the low priced store. Low priced sites don't allow for any margin of error. If there's a problem or you have a problem with your product, low priced hvac stores may return to you reluctantly and usually because your threatned them. More often then not, you wind up with the problem and with no Customer Support to help you.
