Commercial HVAC Replacement — Planned, Not Panicked
Every commercial HVAC system has a lifespan. The question isn’t whether you’ll replace it — it’s whether you’ll do it on your timeline or the equipment’s. Circulating Air helps Los Angeles facility managers plan and execute system replacements that minimize downtime, maximize efficiency, and eliminate the escalating repair cycle.

The Problem
The Repair Spiral: When Fixing It Costs More Than Replacing It
You know the pattern. The first repair was reasonable. The second was expected. By the fifth emergency call in 18 months, your maintenance budget is gone and the system still can’t hold setpoint on a 95-degree day.
Aging commercial HVAC equipment doesn’t just break more often — it breaks more expensively. Parts get harder to source. Refrigerant becomes obsolete. Energy costs creep up as efficiency degrades. And every breakdown generates tenant complaints, service disruptions, and management headaches that don’t show up on the repair invoice.

What We Do
Strategic Replacement — Engineered for the Next 20 Years
We don’t just swap old equipment for new. We reassess your building’s needs, evaluate what’s changed since the original installation, and design a replacement system that accounts for current occupancy, updated codes, and modern efficiency standards.
System Assessment & Planning
Detailed evaluation of existing equipment condition, remaining useful life, and repair-vs-replace economics — plus load recalculation for current conditions, not the original design assumptions.
Equipment Selection
Brand-neutral recommendations matched to your building type, budget, and operational requirements. We spec what fits your building, not what earns us the biggest margin.
Phased Replacement
For multi-unit buildings, we sequence replacements to maintain partial climate control throughout the project. One zone comes down, gets replaced, comes back up, then the next.
Refrigerant & Controls Integration
Transitioning from R-22 or other legacy refrigerants to current-standard systems with full decommissioning, plus connecting new equipment to existing building automation systems.
Utility Rebate Coordination
We identify and help you capture available SCE, SoCalGas, and LADWP rebates and incentive programs for high-efficiency replacements.
Why Circulating Air
Why Facility Managers Trust Us With Replacement Projects
Six decades replacing what other contractors installed. We’ve replaced commercial HVAC systems across every era of Los Angeles construction — from 1960s office buildings with original equipment to 2000s developments ready for their first major lifecycle replacement.

How Commercial HVAC Replacement Works
What to Expect
1
Assessment & Recommendation
We inspect your existing system, review maintenance history, and provide a clear repair-vs-replace analysis with projected costs for both paths. No pressure — just the math.
2
System Design & Rebates
If replacement is the right move, we engineer the new system around your building’s current reality and check all applicable utility incentive programs before finalizing equipment selection.
3
Phased Installation
We remove old equipment, install new systems in planned phases, and coordinate with your operations schedule. Occupied buildings stay operational throughout.
4
Commissioning & Balancing
New equipment is tested under load, airflow is balanced across all zones, and controls are calibrated. We verify performance matches design intent before signing off.

Common Questions About Commercial HVAC Replacement
What facility managers ask before committing to a system replacement.
How do I know if it's time to replace rather than keep repairing?
Can you replace our system without shutting down the building?
In most cases, yes. We specialize in phased replacements that keep partial climate control operational throughout the project. For single-system buildings, we schedule the cutover during the mildest weather window or during planned building closures. Our crew depth — 150+ employees — means we can staff multiple phases simultaneously to compress the timeline.
How long does a commercial HVAC replacement take?
A single rooftop unit swap can be completed in 1–3 days. Multi-unit phased replacements across a large facility may run 4–12 weeks depending on scope and equipment lead times. We provide a detailed schedule during the proposal phase so you can plan around the work.
What happens to our old equipment?
We handle full removal, including refrigerant recovery and reclamation per EPA standards. Old equipment is disposed of or recycled through certified channels. You don’t have to coordinate anything — removal and disposal are built into the project scope.
Are there rebates available for high-efficiency replacements?
Yes. SCE, SoCalGas, and LADWP all offer incentive programs for qualifying high-efficiency commercial HVAC equipment. We identify applicable programs during the proposal phase and help you capture every available dollar. Rebate availability and amounts change periodically, so we verify current programs at the time of your project.
What happens after the replacement is complete?
