What’s the difference between a verified estimate and a quick estimate?
- Both estimate types include the unit, a real vent kit, and professional install.
- Quick estimates use the simplest vent kit and a baseline install — a fast starting number, no questions.
- Verified estimates confirm the unit should fit and work in your space, then price the exact vent kit for your venting plus any install add-ons you’ll actually need.
