Before You Call: Ac Installation Answers

Why does correct sizing matter more than just matching my old unit?+

An oversized condenser cools the air quickly but shuts off before it can remove humidity, leaving the house feeling muggy despite a cold thermostat reading.

What does a SEER2 rating actually mean for my bill?+

We show real numbers for your specific situation rather than a generic efficiency pitch.

Do I need new ductwork with a new AC installation?+

Not always — existing ducts are evaluated during the site visit and only modified when the load calculation or condition genuinely requires it.

Will installing central air require an electrical panel upgrade?+

Depends on your existing panel capacity and the new equipment's draw — we check this during the consultation.

How long does a typical AC installation take?+

We give a realistic timeline during the written estimate, not a generic promise.

Do you offer ductless options if central air isn't practical for my home?+

We'll give an honest comparison rather than defaulting to whichever system is easier to sell.
