Oversized HVAC Equipment: 5 Reasons Why It’s A Problem

As we’ve touched on in the past, the HVAC system has become a problem source for home efficiency, and oversized HVAC equipment is a problem with consequences that, perhaps, are not being adequately communicated.

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. Comfort Oversized equipment causes temperature swings. Shorter cycles leave your system playing catch-up—particularly along the perimeter of your home—because, by the time your thermostat feels the change in temperature, the temperature has dropped or risen several… Continue reading
