Questions people ask before calling

How long does installation take?

A straight replacement usually takes one day. If ductwork needs changes, plan for two or more.

What warranty should I expect?

Most systems carry a 10-year parts warranty when registered, plus a labor warranty from the installer — ask how long their labor coverage runs.

What should I ask before I sign?

Ask about the equipment model, efficiency rating, labor warranty, permit handling, and what happens to your old unit.

Do I need new ductwork too?

Not always. A good installer inspects the ducts and tells you honestly whether they can stay.
