Frequently Asked Questions
What size AC do I need?
It depends on insulation, windows, sun exposure, ductwork and layout. A load calculation sizes it correctly; an oversized unit can short-cycle and leave the home clammy.
Should I consider a heat pump instead?
Many Colorado homeowners do. A heat pump cools like an AC and also provides efficient heat. Incentive programs change often, so we'll help you check what's currently available.
