Free estimates · expert technicians · honest, upfront advice.

AC replacement in Aliso Viejo swaps a worn or inefficient air conditioner for a new, right-sized one that cools better for less. Bloom removes the old unit, installs and charges the new one, and tests it. A correctly sized AC cools evenly and runs efficiently. Call (949) 593-2781 for a free estimate.

When Replacing Beats Repairing

Air conditioners last about 12 to 15 years. Past that, efficiency falls, repairs get frequent, and older refrigerants get expensive and are being phased out.

What happens if you wait:

  • A failing compressor can cost nearly as much as a new system.
  • Low efficiency raises your bill every hot month.
  • Older R-22 refrigerant is costly and hard to find.
  • A mid-summer failure forces a rushed decision.

How We Replace Your AC

The right AC is sized to your home, then installed to run efficiently:

  • Load calculation and correct tonnage sizing
  • Removal and safe disposal of the old unit
  • New high-efficiency (SEER2) AC installation
  • Refrigerant charge, thermostat, and full testing

FAQ

AC Replacement FAQs

How do I know what size AC I need?

Size comes from a load calculation based on your home's square footage, insulation, windows, and sun exposure — not a guess. An oversized AC short cycles and leaves humidity; an undersized one never keeps up. We size it correctly.

How much does a new AC cost in Aliso Viejo?

A new home AC system in the area commonly runs a few thousand dollars, depending on size, efficiency, and any ductwork. This is a general range, not a quote — call for a free, on-site estimate for your home.

What is SEER2 and why does it matter?

SEER2 is the current efficiency rating for air conditioners. A higher SEER2 unit uses less power for the same cooling, which lowers your summer bills. We'll show you the trade-off between price and efficiency.

Can you replace my AC in one day?

Most straight AC swaps take part of a day. Jobs with ductwork or electrical changes can take longer. We give you a clear time window with your free estimate.
