When it comes to cheeseburgers, paychecks and defensive tackles, bigger is better. But, for HVAC equipment, that’s not always the case. As we’ve touched on in the past, the HVAC system has become a problem source for home efficiency, and incorrect equipment size is a problem with consequences that, perhaps, are not being adequately communicated. Here are five reasons that oversized equipment is no good: 1. Dollars & Cents Oversized equipment has a higher initial cost and costs more to operate.

Longer run times reduce cycle losses and bolster efficiency. It’s also just plain hard on your stuff. An oversized compressor is destined for a short life. 2.

The short story is this: The pioneers of energy efficiency came primarily from government-funded weatherization programs around four decades ago.
