Frequently asked

Is bigger equipment better?

Oversizing can cause comfort and humidity problems. Sizing is a technical question for a licensed professional, not a price question.

Why do quotes differ on ducts?

Because duct condition is judgment-based. Getting the assumption written down is what makes bids comparable.
