In a commercial lease, who pays for HVAC replacement is decided by the lease wording, not by a general rule. Many net and triple-net leases put repair and maintenance on the tenant, while replacement of major equipment may stay with the landlord, be shared, or be recovered through operating costs. The lease decides. A condition assessment tells both sides what the equipment is likely to need before anyone signs.
Disputes over rooftop units show up again and again in commercial real estate forums: a tenant paying for servicing on a unit that is near the end of its life, or a landlord facing a replacement the tenant thought was covered. This guide is not legal advice. It explains the questions to raise with your lawyer or broker, and how a Building Condition Assessment gives those negotiations facts instead of assumptions.
Who Usually Pays for HVAC in a Commercial Lease?
There is no single Alberta answer, because each lease allocates costs differently. Most disputes come down to how the lease treats a few terms:
Repair versus replacement. Some leases make the tenant responsible for "repair and maintenance" but are silent or different on "replacement."
Capital versus operating costs. Whether a replacement can be passed through as an operating cost, amortized over its useful life, or excluded entirely.
Equipment serving one premises versus the whole building. A rooftop unit dedicated to one bay is often treated differently from central plant.
Service contract requirements. Many leases require the tenant to keep a maintenance contract in place, and a missing service history can shift the argument.
Condition at the start of the term. If the lease says the tenant returns the premises in the same condition, the starting condition matters.
Your lawyer interprets the clause. A condition assessment supplies the facts the clause depends on.
Why Does the Age and Condition of the Rooftop Unit Matter Before You Sign?
A unit with a few years of remaining life left can become a replacement during the lease term, and whoever carries that cost should know it before signing. Alberta's long heating seasons and hail exposure make this a practical question, not a theoretical one.
For Tenants
Ask what you are inheriting. If the lease makes you responsible for HVAC, an older unit with a patchy service history can turn a reasonable rent into an expensive term.
For Landlords
Know your capital exposure across the building. If replacement stays with you, a building-wide view of equipment age and condition helps you plan and price renewals.
For Property Managers
Make recoveries defensible. When costs are passed through, a documented condition baseline helps explain why a replacement was needed.
What Does a Building Condition Assessment Show About HVAC and Other Lease Items?
A Building Condition Assessment documents the observed condition, approximate age, visible deficiencies and estimated remaining useful life of the building's major systems, with Opinions of Probable Cost when scoped. At Brookstone, the work follows ASTM E2018-24 methodology, with systems and depth set in the written proposal.
For lease negotiations, the most useful sections are usually:
HVAC. Rooftop units, make-up air units, unit heaters, exhaust fans and controls, with nameplate data where it is readable and accessible.
Roofing. Membranes, flashings and drains, which often sit next to the HVAC question in the lease.
Envelope. Storefronts, doors, sealants and walls.
Electrical and plumbing. Service and distribution at a visual level.
Site. Paving, parking and drainage that may be shared cost.
Service records and nameplates help, but the assessment is based on what can be observed and what documents are provided. It is not a mechanical engineering design or a warranty.
When Should a Tenant or Landlord Order an Assessment?
Order it before the lease is signed or renewed, while terms can still change. Once the lease is executed, the assessment only tells you what you already agreed to pay for.
Before a new lease. Tenants use it to negotiate HVAC responsibility, rent abatement or a landlord replacement obligation.
Before a renewal. Both sides can revisit cost allocation when equipment has aged during the first term.
At move-in. A documented starting condition helps with end-of-term obligations.
Before a building purchase. Buyers should understand which lease obligations sit with the landlord.
Before budgeting operating cost recoveries. Landlords and managers can plan replacements across tenants.
What Questions Should You Raise With Your Lawyer or Broker?
Take the assessment findings to the people negotiating the lease. Useful questions include:
Does "repair" in this lease include replacement of major components?
If a rooftop unit fails in Year 3, who pays, and can any of it be recovered through operating costs?
Is there a cap, amortization period or exclusion for capital items?
What service records must the tenant keep, and from when?
Does the condition documented at move-in define the return condition?
Brookstone provides the building facts. We do not give legal advice on lease interpretation.
What Lease Structures Do Alberta Commercial Tenants Usually See?
Alberta commercial leases come in many forms, and the label alone doesn't tell you who pays for HVAC. Common structures include:
Net and triple-net (NNN) leases. The tenant pays base rent plus a share of operating costs, property taxes and insurance. Many also make the tenant responsible for repairs and maintenance inside the premises, sometimes including equipment that serves only that space.
Gross or semi-gross leases. The landlord covers more of the building costs inside a single rent figure, though repair obligations still depend on the wording.
Single-tenant buildings. A tenant leasing a whole building may take on most building systems, including the roof and HVAC, with replacement obligations spelled out separately.
Multi-tenant retail and office. Shared systems, common-area maintenance (CAM) and operating-cost pools are common, and rooftop units often serve individual bays.
Each lease defines its own terms. Read the definitions section carefully, because words like "repair," "replace," "capital" and "operating costs" are often defined there.
How Long Do Rooftop Units Usually Last, and Why Does It Vary?
There is no fixed lifespan for a rooftop unit. Remaining life depends on the equipment, how it has been maintained, how hard it has worked, and what Alberta weather has done to it.
Factors That Shorten Remaining Life
Missed servicing. Dirty coils, worn belts and neglected filters make equipment work harder.
Heavy heating loads. Long Alberta winters put many hours on gas-fired heat sections.
Hail. Damaged coil fins and cabinets reduce efficiency and can let water in.
Undersized or oversized equipment. Short cycling or constant running both add wear.
Tenant changes. A space converted to a restaurant or gym can demand far more from equipment sized for an office.
Factors That Support Longer Life
Documented maintenance contracts with seasonal servicing.
Component replacements such as compressors, heat exchangers or controls.
Light, steady loads in a space that matches what the equipment was designed for.
A condition assessment considers these factors together. That is why two units of the same age can have very different remaining-life estimates.
What Else Besides HVAC Belongs in the Lease Conversation?
HVAC is the most common dispute, but it is rarely the only big-ticket item. Before signing, look at:
Roofing. Who repairs leaks, and who replaces the membrane at the end of its life? Rooftop equipment curbs and roof penetrations often sit at the boundary between HVAC and roof responsibility.
Parking and paving. Asphalt resurfacing and concrete repairs are often recovered through operating costs in multi-tenant properties.
Storefronts and exterior doors. Glazing, frames and door hardware wear quickly at busy entrances.
Plumbing and grease interceptors. Especially relevant for restaurant tenants.
Electrical service. Whether the existing service can support the tenant's equipment, and who pays to upgrade it.
Fire protection and life safety. Sprinkler modifications and alarm work triggered by tenant improvements.
Accessibility. Washrooms and entrances may need upgrades during renovation.
A Building Condition Assessment can document all of these in one report so the lease negotiation covers the whole picture, not just the unit on the roof.
How Do Landlords Use a BCA Across a Multi-Tenant Building?
For landlords, a building-wide BCA turns scattered equipment into a capital plan. Instead of reacting each time a tenant calls about heat, you can see which units are near the end of their life and plan replacements.
Lease renewals. Know which equipment will need replacement during the next term before you set renewal terms.
Operating-cost recoveries. A documented condition baseline helps support recoveries where the lease allows them.
Capital budgeting. Group replacements to reduce crane mobilizations and contractor costs.
Acquisitions. Buyers can see which lease obligations sit with the landlord and which have been passed to tenants.
Our guide on Building Condition Assessments for Alberta capital budgets covers how owners turn findings into a multi-year plan.
What Should a Tenant Do at the End of the Lease?
End-of-term obligations often depend on the condition at the start. If the lease requires the premises to be returned in the same condition, normal wear excepted, the move-in record matters.
Keep the move-in assessment and photos with the lease file.
Keep service records for every maintenance visit required by the lease.
Document repairs and replacements you paid for during the term.
Consider an exit assessment if there is any disagreement about condition.
Clear records on both sides make end-of-term discussions shorter and less expensive.
Common Questions About HVAC in Alberta Commercial Leases
Does the tenant always pay for HVAC in a triple-net lease? No. Many NNN leases put maintenance and repair on the tenant, but replacement obligations vary. The lease wording decides.
Can a landlord pass a replacement through operating costs? It depends on the lease. Some leases allow capital costs to be recovered, sometimes amortized over the useful life, and others exclude them.
What if the unit was already old when I signed? That is exactly why condition matters before signing. Your lawyer can advise on your position. An assessment documents the facts.
Is a Building Condition Assessment the same as an HVAC service report? No. A service report focuses on maintenance tasks. A BCA documents condition, remaining life and cost across the building's major systems.
How Does a Condition Assessment Fit Into Lease Negotiations?
The assessment is a fact-finding tool, not a negotiating position. How each side uses it depends on its interests and its advisors.
For Tenants
Ask for a landlord replacement obligation for equipment the assessment shows is near the end of its life.
Ask for a rent abatement or allowance if you accept responsibility for older equipment.
Ask for a cap on your share of capital recoveries, if the lease allows them.
Confirm the service standard you must meet and when it starts.
For Landlords
Price the risk accurately. Replacements you will carry during the term belong in your capital budget and renewal strategy.
Set clear maintenance requirements so equipment is serviced properly by tenants.
Document condition at turnover to support end-of-term discussions.
For Both Sides
A shared, independent report reduces arguments about facts so negotiations can focus on terms. Some parties agree in advance to share one assessment and its cost.

What Does a Lease-Focused Assessment Report Look Like?
A lease-focused BCA uses the same methodology as other BCAs, with emphasis placed where the lease decisions are. At Brookstone, that usually means:
An equipment schedule listing rooftop units and other HVAC equipment with location, approximate age where identifiable, observed condition and estimated remaining useful life.
Photos tied to each piece of equipment and each significant finding.
Roof condition around equipment curbs and penetrations.
Opinions of Probable Cost for repair and replacement when scoped.
A short summary that a lawyer, broker or property manager can read quickly.
Stated limitations such as winter access, locked spaces or equipment that could not be operated.
The report is reviewed and stamped by an APEGA-licensed Professional Engineer, so all parties know who stands behind the findings.
Why Do Rooftop Unit Disputes Happen So Often?
Most disputes come from three gaps: unclear wording, no starting condition record, and missing service history. Each gap is easier to close before signing than after a failure.
Unclear wording. "Repair and maintain" means different things to different people when a compressor fails.
No baseline. Without a record of condition at the start, neither side can prove what the tenant inherited.
Missing records. Without service records, it is hard to tell whether failure came from age or neglect.
A condition assessment addresses the second gap directly and helps with the third by recording what records were available.
Which Alberta Property Types See the Most HVAC Lease Questions?
Some property types put more strain on HVAC equipment and create more lease questions.
Restaurants and food service. Kitchen exhaust, make-up air and higher cooling loads add equipment and wear. Grease exhaust and fire suppression bring their own responsibilities.
Retail plazas. Each bay often has its own rooftop unit, so equipment ages unevenly across tenants.
Fitness and medical uses. Higher occupancy, ventilation needs or longer operating hours increase run-time.
Office space. Shared central systems and zoning create questions about which costs belong to which tenant.
Light industrial and flex bays. Unit heaters, make-up air and dock-area heating work hard in Alberta winters.
Converted spaces. A space that changes use may need equipment that was never designed for the new load.
If your use is more demanding than the previous tenant's, raise it early. Equipment sized for an office may not serve a restaurant or gym well.
What Questions Should You Ask the Landlord or Property Manager?
Before signing, ask the landlord or property manager for information that helps the assessment and the lawyer.
How old is the equipment serving the premises? Ask for nameplate photos or installation records.
Who has serviced it, and how often? Ask for service reports from the past few years.
Have there been major repairs? Compressor, heat exchanger or control replacements change the remaining-life picture.
Are there warranties? Note what they cover and when they expire.
Has the equipment been damaged by hail? Ask about insurance claims or repairs.
How are costs recovered today? Ask for a recent operating cost reconciliation if the property is multi-tenant.
Answers to these questions, combined with an independent assessment, give both sides a clearer starting point.
