AC Installation & Replacement in Corona, CA

Corona summers are long and they hit hard. From June straight through to October, you’re depending on your AC to do its job every single day. When it can’t keep up or it finally gives out, All Pro Cooling, Heating, Plumbing & Electrical installs new systems for Corona homeowners who want the job done right.
We’ve had an office in Corona since 1991 and our techs run calls across the city regularly, from the neighborhoods off the 91 near Norco to the newer developments on the south end toward Eastvale. We know the housing stock here and what it takes to cool it through an Inland Empire summer.

When Replacement Makes More Sense Than Another Repair

Not every repair is worth doing. Here are the situations where a new system is the smarter financial call:

  • It’s 10 or more years old and starting to need regular attention
  • A single repair is going to run more than 40 to 50 percent of what a new system costs
  • Runs all day and the house still never really cools down
  • Energy bills have been climbing without any obvious explanation
  • R-22 refrigerant is what it runs on. It’s no longer in production and gets more expensive to source every year

Both options go on the table before we do anything. Repair gets a fair look. If replacement is the smarter move, we’ll show you exactly why with the numbers behind it.

What We Install

All Pro installs central split systems, heat pumps, and ductless mini-splits. For most Corona homes with existing ductwork, a central system is the most cost-effective choice. If the ducts are in poor shape, we’ll tell you that upfront before recommending you put a new system on them.
Heat pumps handle both cooling and heating from one unit and perform well in Corona’s mild winters. Ductless mini-splits are a good fit for room additions, garages, or spaces where extending ductwork isn’t practical.
On efficiency, we focus on SEER2 ratings. A higher number means lower monthly operating costs. We’ll show you the real payback difference between efficiency tiers so you can make an informed decision.

How the Installation Goes

We start with a home assessment. We look at your existing equipment, check the ductwork, and run a load calculation sized to your home. Then we put together a written estimate with the specific equipment we’re recommending and what it costs.
Most installations wrap up in one day. We remove the old system, install the new equipment to manufacturer specifications, and run a full performance test before we leave. You get a walkthrough on the controls and thermostat before we pack up. And if anything feels off in the days after, call us and we’ll come back.

Financing Available

A new AC system is a significant purchase. All Pro offers financing options for qualifying homeowners so you don’t have to pay for everything upfront. Ask about current offers when you call.

How long does an AC installation take in Corona?

One day for most installs. If there’s significant ductwork involved, it may extend to two. We’ll tell you before we start.

Do you handle permits?

Yes. We pull all required permits and schedule inspections. You don’t have to deal with the city on that.

Is a heat pump a good fit for Corona?

Yes. Corona’s winters are mild enough that heat pumps run efficiently year-round. You get one system that handles both heating and cooling without a separate furnace.

What happens to my old equipment?

We remove and dispose of the old system as part of the installation. That’s included.
