The fastest way to a fair number is to ask every business the same questions and compare the answers. 1. ### What does a typical project cost? Prices on websites are rare and rarely comparable. We ask for the range clients actually paid in the last 12 months, and what that range includes. 2. ### How long does a typical project take? A schedule tells you how a business plans. We ask for the time from signed contract to finished job, and what most often makes it late. 3. ### What should homeowners prepare before asking for a quote? A better first conversation gets you a firmer price. We ask what saves the most time and money before anyone visits. 4. ### What kind of work do you specialize in? Most businesses say they do everything. We ask what they do most and best, and what they turn down. 5. ### What expensive mistake do homeowners commonly make? Businesses see the same mistakes again and again. We ask for the one that costs their clients the most. ## See how Deltona businesses answer 5 local hvac contractors businesses, the same five questions, side by side.
