Is it illegal to run an R-22 air conditioner in Arizona?

No. Owning, running and servicing R-22 equipment remains legal. What ended is the manufacture and import of the refrigerant itself, so service relies on reclaimed supply.

How do I know if my system uses R-22?

The outdoor unit's data plate lists the refrigerant, often as R-22 or HCFC-22. Systems installed before 2010 are likely candidates. Read the plate; do not open any panel to find it.

Can I just replace the outdoor unit and keep my indoor coil?

Not with current refrigerants. The indoor coil and outdoor unit must be matched for the same refrigerant and capacity. A mismatched pairing loses efficiency and can shorten compressor life.

My technician suggested a drop-in refrigerant. Should I accept?

Ask three things: whether the system currently leaks, how the blend behaves at Phoenix outdoor temperatures, and how the mixed charge will be labeled. If the system leaks, a blend is money into the same hole.

Will a new system need different ductwork?

Often the ducts need sealing and sometimes resizing, especially if the new system is a different tonnage or a variable-speed model. Our duct sealing page explains what a leakage test reveals.

Should I replace a working R-22 system on a rooftop package unit?

The same logic applies, with a crane and curb adapter in the scope. Our rooftop unit replacement page covers the specifics.

Are there incentives for replacing an R-22 system?

Utility programs and manufacturer promotions exist and change often. We do not publish amounts; the current list lives on our rebates page.

How long does an R-22 replacement take?

Most split-system swaps are a one-day job when electrical and ducts are ready. Line set rerouting, attic air handlers and panel work extend it. Your evaluation will state the expected duration in writing.

R-22 System Replacement: Retiring the Old Refrigerant on Your Terms

If your air conditioner still runs on R-22, it is running on a refrigerant that has not been manufactured in this country for years. This page explains what that means for repairs, why so-called drop-in blends deserve caution, and how to replace the system before summer makes the choice for you.

Why the old system got expensive

Somewhere in the Valley this afternoon a technician is standing beside a condenser from the previous century, gauges on, working out how to say it kindly. The system is low on R-22. The United States stopped producing and importing R-22 at the start of 2020. What remains is reclaimed gas and whatever distributors stockpiled, and scarcity sets the price. Each leak repair on an old system is a purchase of a shrinking product, poured into equipment that predates current efficiency minimums and is asked to survive 112-degree afternoons on an APS or SRP time-of-use plan. The gas is one cost. The electricity is the quieter one. Our refrigerant guide covers the chemistry; this page covers the decision.

The phase-out in plain language

R-22 depletes the ozone layer, and an international agreement scheduled its retirement decades ago. New equipment using it stopped in 2010. Production and import ended in 2020. It remains legal to own an R-22 system, to run it, and to service it with reclaimed refrigerant. Nobody will make you replace it. The market will simply keep raising the cost of not replacing it. One more wrinkle: the refrigerant that replaced R-22 is now being phased down for new equipment in favor of lower-global-warming blends. A system bought today rides on that newer generation, which is one reason to buy once rather than twice.

The drop-in blend problem

Alternative blends marketed for R-22 systems exist, and some technicians reach for them. Understand what you are agreeing to.

They are not truly drop-in. Pressure and temperature behave differently, and capacity in extreme heat is usually lower, which in Phoenix is the whole point.
Oil compatibility. Older systems use mineral oil; many blends return oil to the compressor less reliably without changes.
Mixing. Adding a blend to residual R-22 creates a cocktail no gauge can identify, and the next technician has to guess.
The leak is still there. A blend does not fix the hole. If the system lost charge once, it will lose the new gas the same way.

A blend can be a reasonable bridge for a tight system with one honest season left before a planned replacement. It is a poor answer for a leaking one. Our refrigerant leak repair page explains how leaks are found and why topping off is not a repair.

What changes the scope

An R-22 swap is a whole-system project, not a condenser swap.

Indoor coil. An R-22 evaporator coil cannot run on current refrigerants. The coil, and usually the air handler or furnace it sits on, is part of the job.
Line set. Old copper carries mineral oil residue and may not be rated for the higher pressures of newer refrigerants. Replacement or a proper flush is decided on site, and the route through a wall or attic drives labor.
Electrical. The new condenser's nameplate sets breaker and wire requirements, and older panels do not always cooperate.
Home type. A rooftop package unit has no line set but needs a crane and a curb match. A split system in a two-story tract home may need attic work in a 155-degree space.
Ducts and sizing. A new system on leaking ducts or the old tonnage repeats the old mistakes. A load calculation and duct assessment belong in every bid.
Recovery. The old refrigerant must be recovered by certified technicians, never vented. It is the law, and it is the right thing.

Planning before the summer failure

A decision made in October is calmer than one made at four in the afternoon in July with the house at 90 degrees inside. Have the system evaluated while it still runs. Get the load calculation done. Sort out financing on approved credit so the paperwork is not part of the emergency. Then schedule the install for a shoulder month when crews are not triaging. Honesty demands the other side too: a tight R-22 system that holds its charge, cools the house, and belongs to someone moving next spring can be maintained and left alone. The repair-or-replace guide gives you the arithmetic, and a maintenance visit each spring keeps a leak from surprising you.

Questions to ask any bidder

Which refrigerant does the proposed equipment use, and is it the current generation?
Are the indoor coil and air handler included, or only the outdoor unit?
Will the line set be replaced, flushed, or left as is, and why?
Did you run a load calculation, or copy the old tonnage from the nameplate?
How will the old R-22 be recovered and documented?
What electrical changes are needed, and are they in the price?
Is the quote flat-rate and complete before the crew arrives?

The next step

A web page cannot tell you whether your system is leaking, how much charge it holds, or what tonnage your house needs. An on-site evaluation can, and it ends with a written plan you can act on this season or next.
