About same-day serviceFlowProHVAC is a family-owned heating and cooling contractor based in Corona, California. The business started in 1994 and has been built almost entirely on word of mouth — homeowners and property managers who keep calling us because we do the job right and price it fairly.
We are a small team by design. When you call us, you get a real technician — not a sales script. We will tell you when a system can be repaired, when replacement is the smarter call, and we will never pressure you into something you do not need.
Mon – Sat: 7 AM – 7 PM
Sunday: Closed
Real homeowners and property managers across the Inland Empire.
"They installed a new system in our home last summer. Professional, efficient, and left everything spotless. Comfortable house all season."
"As a property manager I've worked with many HVAC companies. FlowPro is our exclusive partner now — reliable, fair, and they pick up the phone."
"They beat the estimate I got from another company and installed a Carrier system the next week. Honest people, clean work."
Three decades of repeat customers doesn't happen by accident.
When you call, you reach the technician doing the work — not a national call center.
We diagnose the problem, explain it in plain English, and give you the price before any work starts.
If your system has years left, we'll repair it. We'll only recommend replacement when the math actually works.
Drop cloths, shoe covers, properly sealed ductwork, and a tidy job site when we leave.
The questions we get most often from new customers in Corona and nearby cities.
We install top American brands — Carrier, Trane, Lennox, American Standard, and Rheem. We recommend the right brand and efficiency tier for your home and budget rather than pushing one brand on every customer.
Yes. Every new HVAC installation comes with a 10-year manufacturer parts warranty when properly registered — and we handle the registration for you on installation day. Coverage typically includes the compressor (or heat exchanger), coils, and major internal components. Labor warranty terms are separate.
Yes. Bring us a written, itemized estimate from any licensed California HVAC contractor for the same equipment and scope, and we'll beat it. We won't quietly downgrade equipment to win on price — same brand, same scope, lower number.

Most days during cooling and heating seasons, yes — especially if you call early. We prioritize urgent calls and most repairs are completed the same day. Our hours are Monday through Saturday, 7 AM to 7 PM.
It depends on the size of your home, the SEER rating you choose, and whether your existing ductwork needs work. A typical single-family home in Corona will land somewhere in the $7,000 – $14,000 range for a complete replacement. We provide a detailed written estimate — and we'll beat any written competitor quote on equivalent equipment.
Twice a year — once before cooling season and once before heating season. Regular tune-ups extend equipment life, keep efficiency up, and catch small issues before they become expensive failures. Ask about our maintenance plan.
