Commercial HVAC Maintenance Agreement Checklist

The bakery owner bought “spring and fall maintenance, filters included, priority emergency service.” On the first cold Saturday, a rooftop unit stops heating. The owner expects an included repair. The dispatcher sees an after-hours diagnostic call at the emergency rate.

Neither interpretation appears in the signed agreement. It names no units, lists no tasks, and never explains what priority service means.

Before selling the next fall maintenance visit, write the agreement so the owner, dispatcher, technician, and billing team can answer the same questions. Which equipment is covered? What happens at each visit? What needs another approval? What does the recurring fee actually buy?

Start with an HVAC inspection report for the equipment survey. Present the service and price in an HVAC proposal, then attach the accepted equipment list and task schedule to the HVAC maintenance agreement. Each dispatch becomes a work order; each result becomes a service report.

Those records should carry the same asset IDs, scope, and agreement version. A customer should not discover the repair exclusions while standing beside a failed heater.

The agreement checklist

Use this as a drafting checklist for a U.S. commercial account, not as a substitute for equipment-specific maintenance instructions or state contract review.

ACCA's commercial HVAC resources include maintenance estimating and customer comparison tools. Its older quality maintenance checklist, hosted by DOE makes a useful sales point: compare the written maintenance plan with what the contractor said during the interview. That June 2014 checklist references the 2012 standard; use it for comparison questions, not as evidence of today's technical requirements.

Count and identify the equipment before pricing it

“Three rooftop units” is a starting description. It is not an equipment schedule.

Give every included asset a durable ID. Record the full model and serial number, exact location, space served, equipment type, filter arrangement, access route, and any known deficiency. Preserve a nameplate photo and the applicable manufacturer maintenance instructions. If the refrigerant type or charge matters to the service, verify and record it rather than copying an unconfirmed spreadsheet value.

A small retail account might contain:

Price those as three different obligations. For DHP-1, say which accessible tasks are included and which pump work awaits an approved access solution. For RTU-2, document the identification problem and defer affected work until safe isolation can be established.

Do not describe an inaccessible asset as inspected and satisfactory. State the limitation, who will resolve it, and whether a return survey costs extra. Existing problems belong in the baseline record and any separate repair estimate, where the customer can decide what to correct before recurring service begins.

Give every maintenance task a due date or trigger

“Quarterly PM” tells the customer when a truck may arrive. It does not tell the technician what to do.

ASHRAE identifies Standard 180-2018 as the commercial HVAC inspection and maintenance standard addressing thermal comfort, energy efficiency, and indoor air quality. A contractor claiming conformance needs to check the applicable edition, addenda, scope, and full requirements. This article's agreement checklist does not establish conformance.

Build the technical task schedule from the applicable requirements and the installed equipment's instructions. DOE's equipment O&M summaries provide separate resources for different equipment families; a furnace, heat pump, cooling tower, and ductless system should not inherit one undifferentiated list.

For each task, record:

• the asset or component;
• the action and permitted scope;
• the interval or condition that makes it due;
• the manufacturer document or other governing basis;
• the evidence the technician should record; and
• what happens when access, operating conditions, or a defect prevents completion.

For example, a filter row can identify the inspection and replacement trigger, accepted filter, included quantity, condition record, and separate approval for rack repair. It should not simply say “check filters.”

Before the heating season, identify the heating-specific tasks due on the gas/electric unit and the heat pump. If testing requires an operating condition the visit cannot provide, record that limitation and the follow-up. A seasonal appointment label does not prove a heating test occurred.

Use service history to review intervals. A dusty stockroom may need a different filter schedule from the office it shares a roof with. If the frequency changes, preserve the reason and obtain approval when the change affects the price or contractual scope.

Define “filters included” in quantities

List sizes, depths, quantities, accepted type or rating, supplier, replacement allowance, and substitution rules by unit. Also decide who disposes of used filters and what happens when customer-supplied stock is wrong or missing.

An illustrative materials line might say:

RTU-1: four approved filters per change, up to four scheduled changes during the agreement term. Additional changes, specialty media, efficiency upgrades, and rack repairs require a separate price and approval.

That is a quantity example, not a recommended technical interval. The task schedule still needs to match the equipment and site.

EPA's MERV guidance explains filter performance and cautions that higher-efficiency media must suit the system fan and filter slot. A customer request for a different rating therefore needs technical review as well as a price decision.

Carry the installed size, quantity, rating, condition, and exception into the filter change log. If construction dust loads the filters early, photograph the condition and request an additional change or frequency review. Do not quietly consume a year's allowance in one visit and leave the customer to discover the shortage later.

Separate the maintenance fee from corrective repairs

Make the distinction visible beside the price.

Give exclusions a next step. “Condensate pump not accessible; customer to approve an access opening before pump maintenance can be quoted” is useful. “Access excluded” leaves the dispatcher guessing.

Name the repair approver and backup. If an advance spending cap exists, say whether it applies per visit, unit, event, or agreement term, and whether labor, parts, freight, tax, and after-hours rates count toward it. Receiving a service report is not approval for a repair.

Use a separate quote for corrective work and a change order when the agreed asset list, visit frequency, or service obligation changes. If the offer also promises future breakdown repair or replacement for a fee, have its state-law classification reviewed before selling it; the word “maintenance” should not be the only basis for choosing the contract terms.

Keep refrigerant records separate from routine consumables

Avoid a blanket “top off as needed” promise. Observation, leak diagnosis, repair, recovery, and recharge are different tasks, with different approval and record implications.

EPA's Section 608 recordkeeping guidance describes obligations that vary by activity, person, refrigerant, and equipment. Its 50-pound ozone-depleting-refrigerant provisions should not be treated as a universal threshold for every commercial account.

As of October 8, 2026, EPA's HFC management FAQ says the leak-repair provisions in 40 CFR 84.106 began January 1, 2026 for covered appliances with a full charge of at least 15 pounds of a refrigerant containing an HFC or an HFC substitute with a global warming potential (GWP) greater than 53. The residential and light-commercial air-conditioning and heat-pump subsector is excluded from those provisions. A small building or a rooftop location alone does not settle the equipment's regulatory classification.

Have the qualified reviewer identify the applicable rules for each asset. Write who maintains owner/operator records, who supplies service evidence, and who tracks required follow-up. The HVAC refrigerant service-report guide explains how to connect that evidence to the visit.

Treat access and shutdown as part of the appointment

Agree on roof access, keys, escorts, parking, allowed hours, tenant notice, and who can approve a shutdown. Keep alarm codes and credentials in an authorized secure process rather than a widely circulated agreement attachment.

For work covered by OSHA's hazardous-energy standard, the host and outside employer must exchange their lockout/tagout procedures. The agreement should support that coordination. It cannot replace the employer's safety program or authorize unsafe work.

Define the commercial handling of a failed appointment: contact attempts, work completed on other assets, tasks left open, rescheduling, and any return charge. If the customer cannot supply the escort for RTU-2, the report should say “access prevented” with the date and follow-up owner. It should not mark the unit complete because RTU-1 was serviced.

Make “priority emergency service” measurable

Choose the event you can deliver and distinguish it from the event the customer hopes for.

A one-hour acknowledgment target does not promise one-hour arrival. Priority scheduling does not make the repair free. If calls go to unmonitored voicemail overnight, the sales page and agreement should not imply staffed overnight dispatch.

Write the after-hours diagnostic fee, minimum, travel treatment, repair approval, and communication process. Identify critical spaces such as a server closet or temperature-sensitive storage and the customer's contingency contact. Suspected immediate hazards need the appropriate emergency or utility response; an HVAC appointment is not a substitute.

For accounts covering several trades, compare these terms with the small-facility service agreement guide. The customer should understand which vendor receives which call.

Prove the visit by unit and task

Require the service report to show the asset, tasks due, tasks performed, readings with units and operating context, materials installed, findings, photographs, final operating status, and next action. Record settings before and after an authorized change.

Give every unfinished task an explicit status: access prevented, unsafe to perform, customer deferred, operating conditions unavailable, or separate repair required. Include who was told and when. The commercial RTU reporting guide adds detail for controls, operating sequence, and follow-up recommendations.

For the illustrative three-unit site, close the visit with three outcomes: RTU-1's listed tasks completed and drain-pan recommendation still open; RTU-2's affected tasks deferred pending identification correction; DHP-1's accessible work completed and pump access unresolved. One customer signature should not erase those distinctions.

Review changes before renewal

Check replacement units, tenant use, access, consumable consumption, unfinished repairs, and actual call volume before quoting the next term. State how extra assets and changed obligations are accepted during the current term.

Have renewal clauses checked for the governing state and transaction. New York's General Obligations Law §5-903, for example, includes firms and corporations as covered recipients. For covered property service, maintenance, or repair agreements, the contractor must deliver a written renewal reminder personally or by certified mail 15–30 days before the customer's deadline to give notice of termination. That window is measured from the notice deadline, which may be earlier than the agreement's expiration. The section excludes automatic renewal periods of one month or less. A commercial customer is not by itself a reason to skip renewal-law review.

Track the actual expiration, applicable notice deadline, delivery method, price change, and customer decision. A renewal should carry an updated equipment list and open-item record into the next year.

Also state how early cancellation works: who receives notice, when coverage ends, how completed visits and prepaid fees are reconciled, and who receives the service history and outstanding recommendations. Have any cancellation charge or refund restriction reviewed under the governing law before using it.
