Written estimates separate equipment cost from labor clearly.

Ac Installation FAQ

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?+

Higher SEER2 ratings mean more cooling per dollar of electricity, though the payback period depends on your climate and usage patterns.

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

We won't recommend duct work that isn't needed.

Will installing central air require an electrical panel upgrade?+

If an upgrade is needed, we coordinate that work as part of the project.

How long does a typical AC installation take?+

A straightforward condenser and coil swap often completes in a day; conversions requiring new ductwork take longer.

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

Yes — for additions, older homes, or spaces where duct routing is impractical, ductless mini-splits are often the better fit.
