01Heating or cooling repair
Note whether the unit starts, whether the problem affects the whole home, and when it occurs. Include any displayed error code and recent service history. Ask what diagnostics the visit includes and whether the fee is separate from repair work.
02System replacement
Identify the existing system and the goals for a replacement: reliability, comfort, operating costs or a changed floor plan. Ask how equipment selection, duct condition and controls will be assessed before comparing proposals.
03Uneven temperatures and airflow
Describe the rooms affected and whether doors, weather or time of day change the problem. Ask whether the proposed assessment includes the distribution system and controls, rather than only replacing the main unit.
04Maintenance and indoor comfort
State whether you want routine maintenance, a humidity concern investigated or help understanding filtration options. Ask what a maintenance visit includes and which findings would lead to a separate repair recommendation.
