Choosing a refrigeration service agreement, and the rule that changed the math

The rule almost nobody has told you about

Federal leak repair requirements used to be something only large systems worried about. Under 40 CFR 82.157 they applied to appliances holding 50 or more pounds, and only to ozone depleting refrigerants such as R-22. A small walk-in on a modern HFC blend was outside them entirely.

That changed on 1 January 2026. A new rule at 40 CFR 84.106 extends leak repair requirements to appliances containing 15 or more pounds of a refrigerant with a global warming potential above 53, which covers the HFCs and HFC blends in essentially every commercial box installed in the last twenty years.

Most walk-in coolers and freezers hold more than fifteen pounds. If yours does, you now have obligations you did not have in 2025.

For a larger operator there is more. Systems holding 1,500 pounds or more need automatic leak detection under 40 CFR 84.108, with equipment capable of detecting refrigerant vapor at 10 parts per million and alerting at 100. Existing systems installed since 2017 have until 1 January 2027. And from 1 January 2029, supermarket systems, refrigerated transport and automatic commercial ice makers must be serviced with reclaimed refrigerant under 40 CFR 84.112.

None of this is a reason to panic, and we are not going to tell you a service agreement is legally required, because it is not. It does change what you are actually buying. An annual leak inspection performed by a certified technician, documented, and retained for three years is now a compliance activity rather than a nicety, and a service agreement is the ordinary way to make sure it happens and gets written down.

The three shapes these contracts come in

Almost every agreement you will be offered is one of three structures, and they are priced very differently because they transfer very different amounts of risk.

• Time and materials, with scheduled maintenance. You pay a fee for a set number of preventive visits, and repairs are billed as they happen. The contractor carries no repair risk. This is the cheapest and the most common, and for most single-location operators it is the right one.
• Preventive maintenance with labor coverage. The scheduled visits plus labor on covered repairs, with parts billed separately. The middle option, and the one where the exclusions list matters most.
• Full coverage. Parts and labor on covered failures, sometimes with a response time commitment. Priced like insurance, because that is what it is. Worth it when a failure closes you, which is the real question rather than how many repairs you expect.

The useful way to choose is not to guess how often things will break. It is to ask what a day of downtime costs you. A restaurant that loses a full walk-in of inventory and a Friday service is in a different position from a back office break room.

The exclusions are where the agreement actually lives

Coverage pages are written to be reassuring. The exclusions page is where you find out what you bought. These are the ones worth reading in every contract.

• Refrigerant. The single most important exclusion, and very often excluded. Given wholesale HFC prices firmed above $6 a pound in 2026 and retail runs roughly double that, on a charge that depends on your line set length, an agreement that covers labor but not refrigerant has left the expensive part with you.
• How response time is defined. Four hour response can mean a technician on site, or it can mean a returned phone call. Get it in writing, and get it defined for nights, weekends and holidays separately.
• What counts as after hours. The industry structure is consistent, 1.5× for overtime and Saturday and 2× for Sunday and holidays. Find out whether your agreement rate is the straight time rate only, and what the premium applies to.
• Travel and mileage. Excluded from every manufacturer warranty schedule we have looked at, and frequently excluded from service agreements too. If your site is a long run from the contractor's base, this is not a small line.
• Wear items. Gaskets, filter driers, belts and contactors are the things that actually fail. An agreement excluding wear items is excluding most of what a refrigeration system does.
• Pre-existing conditions. Standard, reasonable, and worth pinning down with a documented condition survey at the start so that the definition does not float later.
• Who owns the records. More important than it used to be, for the reason in the first section. If your compliance documentation lives only in the contractor's system, changing contractors means losing your paper trail.

What a preventive visit should actually include

Ask for the task list before you sign. A visit that is a technician looking at a gauge for ten minutes is not maintenance, and you will not be able to tell the difference from the invoice. A real one covers:

• Condenser coil cleaning, which is the highest value task on the list and the one most often skipped. A fouled coil cannot reject heat, which costs capacity and shortens compressor life.
• Evaporator coil and drain pan cleaning, and verification that the condensate drain actually runs.
• Door gaskets checked and documented, not just glanced at.
• Defrost cycle verified through a full cycle, including termination. A defrost fault is invisible until the coil is a block of ice.
• Superheat and subcooling measured and recorded, which is how a low charge gets found before it becomes a failure.
• Electrical: contactor condition, amp draw against nameplate, tightness of connections.
• Temperature verification with a calibrated instrument, recorded.
• The leak inspection, documented, if your system is at or above fifteen pounds.

A written report after each visit, with readings instead of checkmarks, is the difference between maintenance and attendance. It is also what you will want if an inspector or an insurer ever asks.

Certification is not optional, and it is worth verifying

Anyone who opens a refrigerant circuit must hold EPA Section 608 certification. Since 2018 that requirement covers HFCs and not only the older ozone depleting refrigerants, so it applies to essentially all commercial refrigeration work. Certificates must be kept at the place of business.

In Utah there is no separate refrigeration contractor licence. The work sits inside the general HVAC contractor classification, which explicitly covers refrigerated rooms and insulated refrigerated spaces. That classification was in transition through 2026, with new experience, examination and insurance requirements, so verify current status with the Division of Occupational and Professional Licensing instead of assuming.

Ask to see both. A contractor who is comfortable being asked is telling you something useful, and so is one who is not.

Whether it pays

The arithmetic is less mysterious than it looks, and you can do it from the numbers in our repair costs page.

The case for an agreement rests on three things that are genuinely worth money, and none of them is the discount on repairs. First, condenser cleaning on a real schedule, which is cheap and prevents the expensive failure. Second, catching a low charge through measured superheat before it becomes a compressor replacement, where published labor allowances run up to 5.5 hours against 0.75 for a contactor. Third, since January 2026, the documented annual leak inspection and the three year record.

The case against is that a preventive agreement on equipment that is already near end of life is paying to maintain something you should be planning to replace. A contractor who tells you that, instead of selling you the contract, is the one worth having.
