AC Replacement in Cerritos & Los Angeles
Power Pro Plumbing, Heating & Air replaces air conditioners across Cerritos, Norwalk, and greater LA and Orange County, sizing modern high-SEER2 systems with a proper load calculation when an aging unit breaks down repeatedly or drives up bills.
Modern systems are a genuine upgrade, not just a newer box: today's high-SEER2 equipment cools more effectively on significantly less electricity, runs quieter, and manages humidity better. Our certified technicians size the new system to your home with a proper load calculation — the step that separates a great installation from an expensive disappointment.
We make the decision easier too: free estimates, honest repair-versus-replace math, financing options, and $500 off any A/C system, equipment, or installation right now.

What are the signs your AC needs replacing?
Your AC is likely ready for replacement when you see several of these signs together:
- Age past 10–15 years — efficiency and reliability both decline from there
- Cooling bills that rise every summer without a usage change
- Repeated repairs, or a single repair quote approaching half a new system's cost
- Uneven cooling and humidity the system used to handle
- An older unit using phased-out refrigerant that's costly to recharge
- Low SEER-rated equipment that costs far more to run than modern systems
Which AC systems does Power Pro replace and install?
Power Pro replaces and installs every air conditioning system type:
- Central AC systems, matched to your existing or upgraded ductwork
- Ductless mini splits for homes without ducts or with zoning needs
- Heat pumps that replace both AC and furnace with one efficient system
- Hybrid systems pairing a heat pump with gas backup
Why does right-sizing a new AC matter?
Right-sizing matters because an oversized AC short cycles — cooling the air fast but never dehumidifying, wearing itself out with constant starts. An undersized one runs flat-out all day and still loses ground at 4 PM in August. We calculate your home's actual load from square footage, insulation, windows, and duct capacity, then recommend equipment that fits. It's more work than matching the old label, and it's why our installations perform.
AC Replacement FAQs
When should an AC be replaced instead of repaired? +
Once a system is past 10–15 years old, breaks down frequently, cools inadequately, or a repair quote reaches a substantial fraction of replacement cost, new equipment usually wins. Rising energy bills seal the case — old units cost more per hour of cooling every year.
How can I lower my cooling bills with a new system? +
Higher-SEER2 equipment is the biggest lever — modern systems deliver the same cooling on much less electricity. Pair it with a programmable or smart thermostat, sealed ducts, and annual tune-ups, and the difference on summer bills is substantial.
How long does an AC replacement take? +
Most straightforward replacements finish in one day. Projects adding ductwork changes, electrical upgrades, or a system-type switch (like central to ductless) can take longer — your estimate will include an accurate timeline.
Is there a discount on new AC systems right now? +
Yes — $500 off any A/C system, equipment, or installation (residential only; can't be combined with other offers; expires 12/31/26). Free estimates and financing options are available too.
