Questions To Ask Before Replacing Your HVAC
May 16, 2026 · 5 min read
The install matters more than the badge on the equipment. These questions surface the difference.
About the design
Ask whether a Manual J load calculation will be performed, whether ductwork will be assessed, and what static pressure readings they expect. A contractor who sizes from the old unit is guessing.
About the paperwork
Manufacturer warranties often require registration within a set window and annual maintenance to stay valid. Confirm who registers the equipment and what the maintenance obligation is.
- Is the permit included?
- What is the labor warranty length?
- What does the maintenance plan cost and cover?
- Who do I call for a warranty failure?
