HVAC Installation Checklist
An HVAC installation checklist template that runs from delivery through to client handover, and ends at the comparison most installations never get: the commissioning readings set against the design values they were supposed to achieve. An installation is not finished when the unit runs. It is finished when it performs to the figures it was designed to, and the only way anybody knows is that table.
- Commissioning readings compared against the design values
- Warranty registered, with its conditions written down
- Filter and belt sizes captured at handover
- Certificates listed, with nothing accepted outstanding

Who this HVAC installation checklist is for
One installation, four people, and only one of them is still on site a year later.
The installing contractor
A sequence that matches the job, from delivery inspection through pressure test and vacuum to commissioning. It is also the evidence that the work was done properly when a defect is argued about later.
Whoever commissions it
The commissioning table. Design value, measured value, variance, verdict. Without the design column a commissioning sheet records only that readings were taken, not whether they were the right ones.
The facilities team inheriting it
Asset data, filter and belt sizes, the controls strategy and the first service date. This is the only moment that information is easy to get.
The client or project manager
Certificates outstanding, defects at handover and the warranty conditions. Three numbers that decide whether this installation is finished or merely running.
Where new HVAC gets installed
The sequence is the same for a rooftop unit, a split system, a VRF installation, a furnace or a replacement chiller. What changes is what the building does while the work happens. If you run one of these, the sector page goes further than the template does.
- FM service providers
Installations delivered under a contract, where whoever commissions the plant is rarely whoever maintains it afterwards.
FM service provider software - Commercial real estate
Plant replacements in occupied buildings, where the commissioning window is short and the handover data decides fifteen years of servicing.
Portfolio maintenance software - Retail and malls
Store and mall units installed to a rollout program, where the same checklist runs dozens of times and the variance column is the only comparison between contractors.
Retail maintenance software - Healthcare
Clinical and plant installations, where ventilation performance is a design requirement rather than a comfort target.
Healthcare maintenance software - Education
Campus plant replaced in holiday windows, with the handover documentation landing on a small team that was not involved in the project.
Campus maintenance software - Corporate facilities
Office cooling and ventilation upgrades, where the first complaint after occupation is usually traceable to a commissioning reading nobody compared.

What an HVAC install checklist should contain
An HVAC installation checklist records a new heating or cooling installation from delivery through to client handover. It covers pre-installation checks, mechanical pipework, ductwork, electrical and controls, then the commissioning readings compared against the design values, the certificates issued, the warranty registered with its conditions, and the asset data handed to whoever maintains it.
A. Delivery to handover, with the comparison in the middle
| Field | What goes in it | Why it earns its place |
|---|---|---|
| Installation details | Equipment type, make, model, serial, capacity, refrigerant charge and the design reference | Equipment type covers rooftop, split, VRF, chiller, boiler, air handling unit, heat pump and packaged, because the sequence is the same and only the readings change. |
| What it is replacing | New installation, like-for-like replacement, or upgrade | A like-for-like swap inherits the existing ductwork, pipework and controls. Most commissioning failures on replacements come from the part nobody replaced, and this field is why anybody looks there. |
| Pre-installation | Twelve checks from delivery inspection to recovering refrigerant from the old system | Inspect for damage before signing for the delivery. A dented casing noticed on day three becomes an argument. Noticed on the tailgate, it becomes a replacement. |
| Mechanical and pipework | Twelve checks including the pressure hold, the vacuum and the condensate run | The vacuum and the pressure hold are the two steps shortened when a job runs late, and both cause failures months later that nobody traces back to installation day. |
| Ductwork and air distribution | Eight checks covering leakage class, fire dampers, filters and cleaning before commissioning | Filter type and size are recorded here rather than guessed at the first service, which is the whole point of writing it down while the box is still open. |
| Electrical and controls | Nine checks through to the electrical installation certificate | Sensor location is on this list because a thermostat sitting in a draft or above a heat source produces a comfort complaint that looks like a plant fault for years. |
| Commissioning readings | Seventeen measurements, each with a design value, a measured value, a variance and a verdict | The reason the document exists. Air temperatures and split, airflow, static pressure, suction and discharge, superheat and subcooling, charge, currents, water flow, combustion and flue where relevant, and noise. |
| Tests and certificates | Ten entries with who carried it out, the date, result, reference and who holds it | Who holds it matters as much as the reference. A certificate that exists in a contractor's filing cabinet is not a certificate the building can produce. |
| Warranty registration | Supplier, whether it is on file, start, expiry and the conditions attached | Conditions is the field that gets skipped and the field that voids the claim. Annual servicing is the common one, and it is only enforceable if somebody knows about it. |
| Handover to the client | Twelve items from manuals and as-installed drawings to the agreed defects list | Asset data sits here: make, model, serial, filter and belt sizes. Operator training is named rather than noted, so there is somebody to ask. |
| Installation result | Completion, readings in tolerance, certificates outstanding, defects and the acceptance decision | Accepted, accepted with defects, or not accepted. Three outcomes rather than a signature, because the middle one is the honest answer on most jobs. |
| Sign-off and first service | Installed by, commissioned by with qualification, accepted by, and the first service date | The defects liability period and the first service date are written at the same moment, which is the only reliable way either of them reaches a calendar. |
The commissioning section is the one that separates a real installation record from a delivery note with signatures on it. Every reading has a design value next to it, and the design value is what the system was specified to achieve rather than what it happens to be doing. Without that column a commissioning sheet states that somebody measured a supply air temperature, which is almost no information at all. With it, the sheet states whether the installation does what it was bought to do. The difference shows up in the variance: a measurement sitting at the edge of tolerance is not a failure, but it describes a system with nothing left in reserve, and the first time a filter loads or a coil fouls it stops meeting the specification. That is worth knowing on handover day rather than in the second summer. The seventeen measurements span everything that can be wrong in a way the eye cannot see. Air side, the supply and return temperatures and the split between them, the airflow rate and the external static pressure the ductwork is actually imposing. Refrigerant side, suction and discharge pressures, superheat and subcooling, and the total charge weighed in. Electrical, the compressor and fan motor currents, which are the quickest indication of a machine working harder than it should. Water side where it applies, flow rate and the flow and return temperatures. Combustion efficiency and flue gas temperature where there is a burner. And noise, which is the reading nobody takes and the one most likely to generate a complaint that cannot be fixed afterwards without replacing something.
B. What it looks like filled in
One rooftop unit, commissioned and handed over. The result is good, and the lines worth reading are the ones that are not a tick.
| Line | Value |
|---|---|
| Installation | RTU-05, Carrier 48TC, Northgate House |
| Supply air temperature | Design 20.0 °C, measured 19.4 °C |
| Variance against tolerance | -0.6, against plus or minus 1.0 |
| Readings in tolerance | 16 of 17, so 94 percent |
| Certificates outstanding, defects | 0 outstanding, 2 defects agreed |
| Warranty, first service | 18/05/2027 to 18/05/2032, service 18/11/2027 |
Sixteen of seventeen readings inside tolerance is ninety-four percent, and the useful question is which one missed. A single out-of-tolerance reading on an otherwise clean commissioning sheet is not a reason to reject an installation, but it is a reason to write down what it was and what was agreed about it, because it is the thing somebody is most likely to be arguing about in eighteen months. The same applies to the two defects. They are recorded, dated and agreed, which converts them from a dispute into a list with an owner. The number that is not negotiable is the zero. Certificates outstanding at acceptance are far harder to obtain once the final payment has been made, and the ones most often missing are exactly the ones an insurer asks for after an incident. The warranty line carries the other quiet obligation. Five years is a real asset only while the annual servicing evidence exists, which is why the first service was booked six months out on the day of handover rather than left to whoever inherits the building. Once the unit is in service it moves onto an HVAC maintenance checklist, with the jobs raised on an HVAC work order.

How do you commission a new HVAC installation?
Inspect before you sign, do not shorten the vacuum, and measure against the design. Six steps.
Inspect the equipment before signing for it
Check the model and serial against the order and the design while the delivery is still on the vehicle. Damage found after a signature is an argument; damage found before it is a replacement.
Record what the installation is replacing
A like-for-like swap inherits the existing ductwork, pipework and controls, and the inherited part is where most commissioning failures on replacements come from.
Hold the pressure test and the vacuum in full
These are the two steps that get shortened when a job runs late, and both produce failures six months later that nobody traces back to installation day.
Commission against the design values
Take all seventeen measurements, write the design figure beside each one and record the variance. A reading without its design value proves only that somebody measured something.
Close out the certificates before acceptance
Pressure, vacuum, leak, electrical, gas, commissioning, air leakage and water treatment, each with a reference and a named holder. Do not accept with any outstanding.
Register the warranty and take the asset data
Start, expiry and conditions on the warranty. Make, model, serial, filter and belt sizes at handover, then book the first service before anybody leaves.
An installation checklist versus a maintenance checklist
Two documents that look similar and answer different questions. One happens once, the other happens forever.
| Aspect | Installation checklist | Maintenance checklist |
|---|---|---|
| When it runs | Once, at the start of the asset's life | Repeatedly, on a schedule |
| What it proves | The system performs to its design | The system still performs |
| The reference point | The design values | The commissioning figures |
| Who completes it | The installing contractor | Whoever services the plant |
| What it produces | Certificates, warranty, asset data | A service record and defects |
| Where it ends | Acceptance and a first service date | The next service |
The two are connected by one thing, and it is the reason the installation record matters long after the installation. Every maintenance visit for the rest of the asset's life is measured against the commissioning figures, because those are the only readings ever taken from the plant when it was known to be right. A combustion efficiency or an approach temperature on a service sheet means nothing on its own; it means something compared against what the machine did on day one. That is why a commissioning table with a design column, a measured column and a variance is worth the hour it takes, and why a service engineer five years later is grateful for it. It is also why the first service date belongs on this document rather than on a separate system. Routine servicing is a different job with a different checklist, and this page stops at the point the HVAC maintenance checklist takes over. Where the installation is central plant rather than a packaged unit, the same handover feeds a boiler maintenance checklist, a chiller maintenance checklist or a cooling tower maintenance checklist, and a whole building being taken on at once belongs on a site handover checklist.
When the template starts to feel limiting
The file handles one installation well. Four things get difficult the moment the installation is finished and the file is filed.
The commissioning figures end up in a project folder
They are the baseline every future service is judged against, and they live in a folder named after a contract rather than against the asset.
The first service date is a line on a form
It is written on the day everybody is pleased with themselves, and it is six months away in a document nobody opens again.
Warranty conditions stay invisible until the claim
Annual servicing is a condition on most equipment warranties, and nothing connects that condition to whether the servicing is actually happening.
Comparing contractors means opening every file
Variance against defects at handover is the comparison worth making, and on paper it is a stack of jobs nobody puts side by side.
What running this in Facilio looks like
The commissioning does not change. What changes is that the figures survive the project.
Asset Intelligence
Commissioning data stays with the asset
Design values, measured readings, filter and belt sizes and the serial number sit on the asset record rather than in a project folder.
Work Order Intelligence
The first service raises itself
The date agreed at handover becomes scheduled work, which is the only reliable way a warranty condition gets met.
Ops Performance Intelligence
Drift is measured from the baseline
Later service readings are compared against what the plant did when it was known to be right, rather than against a textbook figure.
Audit Report Intelligence
Certificates and warranties are retrievable
The reference, the holder and the expiry stay together, which is the form the question takes when an insurer or an auditor asks.
Hallucination-free by design. Atom AI answers from the records in your tenant rather than generating plausible text, so an empty field reads as empty rather than filled in for you.
Frequently asked questions
What is an HVAC installation checklist?
It is the record of a new heating or cooling installation from delivery to client handover. It covers pre-installation checks, mechanical and pipework, ductwork, electrical and controls, then commissioning, certificates, warranty and handover.
The part that distinguishes it from a job sheet is the commissioning table, where every reading sits beside the design value it was supposed to achieve.
What should an HVAC install checklist include?
Equipment details and what the unit is replacing, pre-installation checks, the mechanical and pipework sequence including the pressure test and vacuum, ductwork, electrical and controls, and the commissioning readings with their design values.
Then the certificate register with a named holder for each, warranty registration with its conditions, a handover list covering asset data and training, and the acceptance decision.
What commissioning readings should be recorded?
Supply and return air temperatures and the split between them, airflow rate and external static pressure, suction and discharge pressures, superheat and subcooling, total refrigerant charge, compressor and fan motor currents.
Then water flow rate and flow and return temperatures where applicable, combustion efficiency and flue gas temperature where there is a burner, and the noise level. Seventeen in all, each against its design value.
Why compare commissioning readings against design values?
Because an installation is not finished when it runs. It is finished when it performs to the figures it was designed to, and a reading recorded without its design value proves only that somebody measured something.
The variance also shows reserve. A reading at the edge of tolerance is not a failure, but it is a system that stops meeting its specification the first time a filter loads.
When should the warranty be registered?
Before the installer leaves site, with the conditions written down. Most equipment warranties carry an annual servicing requirement and are void without evidence of it.
Nobody discovers that until they try to claim, usually several years in, when reconstructing the servicing history is no longer possible.
What should be asked for at handover?
Operation and maintenance manuals, as-installed drawings, commissioning records and certificates, the controls strategy, named operator training, a spares list, emergency contacts and the agreed defects list.
And the asset data, specifically filter and belt sizes. It is one line on a form at handover and a wasted site visit every quarter for fifteen years if nobody asks.
Should an installation be accepted with certificates outstanding?
No. Certificates are far harder to obtain once the final payment has been made, and the ones most often missing are exactly the ones an insurer asks for after an incident.
Defects are different. They can be accepted provided they are listed, dated and agreed, which is why the result section separates accepted with defects from not accepted.
Does this cover routine HVAC servicing?
No. This checklist stops at acceptance and the first service date. Routine servicing is a different job with a different document, and the HVAC maintenance checklist takes over from there.
The connection between them is the commissioning figures, which every future service visit is measured against.
In one paragraph
An HVAC installation checklist works when the commissioning readings are compared against the design values rather than simply recorded, because a unit that runs is not the same as a unit that performs. Inspect the equipment before signing for it, record what the installation is replacing, hold the pressure test and vacuum in full, close out every certificate before acceptance, and register the warranty with its conditions before the installer leaves site.
Running is not the same as commissioned
Measure against the design, close the certificates, register the warranty and take the asset data while it is still easy to get. Once the commissioning figures are buried in a project folder, or the first service date is a line nobody reads again, the paper version has reached its limit.
