Built around how your home uses propane.

Central air conditioning cools your whole home from a single outdoor condenser, delivering even temperatures through your existing ductwork. It's the most popular cooling solution for homes that already have ducts — and modern systems are dramatically quieter and more efficient than units from even 10 years ago.

What a proper central AC replacement looks like

The quality of a replacement matters as much as the equipment itself. We evaluate the existing system and ductwork, size the replacement for the home, verify the refrigerant charge, and complete a full commissioning walkthrough so you know how the system runs.

FAQ

Frequently asked questions

How long does a central AC system last?
A well-maintained central AC typically lasts 12-17 years. Annual tune-ups, clean coils, and correct refrigerant charge are the biggest factors in long equipment life.
What size AC do I need?
Sizing depends on square footage, insulation, window orientation, and ductwork. Oversized systems short-cycle, leave the air humid, and wear out fast. We do a proper load calculation — never a rule-of-thumb guess.
Will a new AC actually lower my electric bill?
It can, especially when an older system is inefficient, improperly sized, or in frequent need of repair. We compare the equipment condition, comfort needs, efficiency ratings, and current utility programs so you can weigh repair and replacement on the same facts.
