The week the temperatures spike is when an HVAC system picks its moment to quit, and the worst part is not knowing if the next callout turns into parts delays, guest complaints, and a bill nobody saw coming. This HVAC service contract puts the maintenance plan in writing, so the client can see what gets checked, what counts as extra work, and when payment is due before anything starts.

The opening section ties the agreement back to the accepted scope, then What I will do explains the seasonal visits and the checks you’ll report on after each one. The wording also draws a clear line around Changes and repairs and What is not included, so a blocked drain line or a refrigerant issue gets priced and approved before work begins. The layout uses fired-earth red with HVAC blue accents under Space Grotesk headings and Inter body text, so the technical parts read like checklists instead of sales copy.

  • It covers seasonal HVAC maintenance at Connects the agreement to the accepted scope and says how scheduling, access, findings, and payment will be handled if anything conflicts.
  • What I will do Defines the seasonal maintenance work, including scheduled visits, what gets checked and cleaned, and what gets sent after each visit.
  • Booking deposit States the 30% deposit due on signing, what it reserves, and what happens if the maintenance is cancelled before or after visit windows are confirmed.
  • Payment Spells out the 30% upfront and 70% on completion structure, invoicing timing, 14-day payment terms, and what happens if payments run late.
  • Ending this agreement Explains how either side can end the agreement, how completed work and approved extras get settled, and when visit notes get released.

Once the contract is in your workspace, you replace the names, dates, and rates to match your terms, then send it to the client to sign online. Signed terms and a clear process for access, reporting, and extras give both sides something to refer back to when a visit needs rescheduling or a repair shows up mid-season.

We went from spending hours on every proposal to creating fully customized ones in under 5 minutes. That's not an exaggeration - we timed it.

What to include in an HVAC service contract

PartWhat it covers

It covers seasonal HVAC maintenance at

Links the contract terms to the accepted scope and explains how scheduling, access, findings, and payment will be handled if anything conflicts.

What I will do

Defines what counts as seasonal maintenance, what gets checked during the scheduled visits, and what gets sent afterwards as notes and operating check summaries.

Booking deposit

Sets the 30% deposit due on signing, what the deposit reserves, and how refunds work depending on whether visit windows were confirmed.

Payment

Explains the 30% upfront and 70% on completion terms, invoicing as work progresses, the 14-day due date, and the conditions for pausing future visits if payments stay unpaid.

Changes and repairs

Covers how changes, added equipment, timing shifts, and repair work get priced and approved in writing before anything extra begins, including refrigerant quotes.

Access and site contact

States what access has to be available at the scheduled time, who the on-site contact is, and what happens when safe access or testing is not possible.

What is not included

Lists exclusions so preventive maintenance doesn’t get confused with an all-inclusive repair plan, including parts, repairs, replacements, and refrigerant work unless agreed in writing.

Leaving things tidy

Explains how the work area is kept contained and cleaned up, what the client needs to protect nearby items, and how snags get raised and checked.

Problems and limits

Sets expectations on workmanship fixes while limiting responsibility for breakdowns, downtime, losses, or delays caused by parts availability and pre-existing faults.

Ending this agreement

Explains how the agreement ends, how completed work and approved extras get paid or refunded, and includes a Signature section for sign-off.

Who it is for

HVAC contractors and heating & cooling service providers who sell seasonal maintenance visits to hotels, restaurants, and other occupied sites that need clear scope, access rules, and payment terms.

The contract in full

It covers seasonal HVAC maintenance at your site, based on the proposal you accepted, and it sets out how I schedule, access equipment, handle findings, and get paid. If anything in the proposal and these terms ever point in different directions, I will flag it before I start so we can agree, in writing, which one we are using.

What I will do

Seasonal HVAC maintenance means I come to your property for the scheduled visits and carry out the checks, cleaning, and basic servicing that keep split systems and mini-splits running steady through the hot months.

What you get is listed below. Each visit is complete when I have run the listed checks I can run on the day, and I have sent you the operating check summary and my notes. If a unit cannot be safely accessed or properly tested, I will note what stopped the test and what I recommend next.

* Two scheduled maintenance visits * Split system preventive service * Mini-split head deep clean * Condensate drain flush record * Electrical and contactor check notes * Operating check summary

Booking deposit

To book seasonal HVAC maintenance, you pay 30% of the total price when you sign. That deposit reserves my time for your visit windows and covers the admin and planning that happens before I arrive on site.

If you cancel before I have confirmed any visit windows in writing, I will return the deposit. If you cancel after I have confirmed visit windows, I will keep enough of the deposit to cover the time I have already set aside and any costs I cannot recover, and I will return the balance. If I cannot take the job on, I will return the deposit.

Payment

To start seasonal HVAC maintenance, you pay 30% when you sign. The remaining 70% is due when the job is finished, meaning both scheduled maintenance visits are complete and I have sent the operating check summaries and notes.

I invoice as the work progresses. Each invoice is payable within 14 days of its date.

If a payment becomes late, I will contact you and ask you to bring the account up to date. If it stays unpaid, I may pause future scheduled visits and hold any visit notes that have not yet been sent, until the balance is paid.

Changes and repairs

This agreement covers the maintenance work listed under Scope. If you want to change the plan, add equipment, change the visit timing, or ask me to do repair work I did not price in the proposal, I will price the change first.

Nothing extra starts until you approve it in writing. That includes common in-between items I find on site, like a blocked drain line, a failed capacitor or contactor, a refrigerant leak, or a coil that needs a deeper wash-down than access allows on a normal visit.

If a unit needs refrigerant added, I will quote that separately before I add any.

Access and site contact

You make sure I can reach the equipment at the scheduled time. That includes the outdoor condenser or rooftop unit, electrical disconnects and panels needed for inspection, indoor heads, drain runs, and any safe roof access points.

You also give me one on-site contact who can make quick decisions (for example, approving safe access, confirming which areas serve which rooms, and authorising a shut-down for testing). If I arrive and I cannot get safe access, or the unit cannot be powered and tested, I will stop and we will reschedule for the next available slot.

If you need to move a visit, tell me as soon as you can and I will offer the next available window.

What is not included

Seasonal HVAC maintenance is preventive service, not an all-inclusive repair plan. Unless we agree it in writing as a separate item, this agreement does not include parts, repairs, or replacement work, including motors, boards, sensors, contactors, capacitors, fan wheels, pumps, insulation, line-set work, or correcting poor installation.

It also does not include refrigerant top-ups, recovery, or major leak repairs. I will do a refrigerant leak check and charge verification where access and operating conditions allow. If I cannot get stable readings because of weather, load, access, or system condition, I will note that.

Deep cleaning that needs unit removal, scaffold/lift hire, or abnormal disassembly is excluded unless priced separately.

Leaving things tidy

I will treat your site like an active hotel or restaurant. I will keep my work area as contained as I can, and I will clean up normal dust and debris created by the maintenance tasks I perform.

Coil and blower cleaning can involve wash-down where access allows. You are responsible for protecting nearby stock, furniture, and finishes if they cannot be moved away from the work area. I do not repaint, refinish, or repair water damage, ceiling stains, or pre-existing corrosion. If I notice an active drain issue or signs of past overflow, I will note it.

If you raise a snag about my work, tell me promptly and I will come back to check it and put it right if it is my mistake.

Problems and limits

I stand behind my workmanship. If I make a mistake during seasonal HVAC maintenance, tell me and I will come back and correct it.

Because I am working on equipment that may be aged, previously repaired, or already close to failure, I cannot promise that maintenance will prevent every breakdown, icing event, or leak. Some failures happen without warning, especially in peak heat.

I am not responsible for losses that sit outside the HVAC work itself, like lost revenue, spoiled stock, guest complaints, or downtime caused by parts availability, power issues, water supply issues, building access limits, or pre-existing faults I did not create.

Ending this agreement

You can end this agreement by telling me in writing. I can also end it in writing if the site is unsafe, access is repeatedly not available, or invoices remain unpaid after I have asked you to bring the account up to date.

When the agreement ends, you pay for the work I have completed up to that date, plus any approved extras already carried out. If you have paid more than the value of work completed, I will refund the difference. If you have paid less, I will invoice the balance.

I will send you any visit notes and operating check summaries that relate to work you have paid for. Once paid, those notes are yours to share for the equipment on site.

Questions about this contract template

What should an HVAC service contract include?

An HVAC service contract usually includes the maintenance scope, how visits are scheduled, site access requirements, deposit and payment terms, how changes and repairs get approved, and what isn’t included. This contract also covers limits on liability, workmanship fixes, and how either side can end the agreement.

Does an HVAC maintenance contract include repairs and parts?

A maintenance contract often covers preventive checks, cleaning, and basic servicing, not parts and repair work. This contract states that repairs, parts, replacements, and refrigerant work are excluded unless agreed in writing as separate priced items.

Do HVAC service contracts require a deposit?

Some do, especially when the provider is reserving visit windows in advance. This contract sets a 30% booking deposit due on signing and explains what happens if the maintenance is cancelled before or after visit windows are confirmed.

How are changes handled in an HVAC service agreement?

A service agreement should say what counts as extra and when pricing gets approved. This contract says changes, added equipment, timing changes, and repair work get priced first and don’t start until approved in writing.

What happens if the technician can’t access the equipment on the day?

Access terms usually cover safe entry, what areas must be reachable, and who can make on-site decisions. This contract says the visit stops and gets rescheduled to the next available slot if safe access or proper testing isn’t possible at the scheduled time.

How do I avoid surprise charges in a heating and cooling maintenance contract?

Surprise charges usually come from unclear scope and vague exclusions. This contract separates maintenance from repairs, lists what isn’t included, and requires written approval before any extra work starts, including refrigerant quotes.
