What makes useful feedback
For a factual correction, note the page title, the specific statement, and the source that supports the change. For calculator feedback, describe the selections and the result you expected. Avoid including personal contact details, equipment serial numbers or a property address.
For equipment or service questions
We do not diagnose equipment, schedule repairs or provide contractor referrals. A qualified local HVAC professional can assess the home and equipment. Use our quote checklist to prepare for that conversation.
