Who Owns the Gaps in an HVAC Bid?
When an HVAC bid excludes work, leaves scope unclear, or says an item is “by others,” the real question is not just what is missing. The real question is who owns the gap.
For property owners, property managers, HOA boards, building managers, and commercial clients, HVAC bids can look complete at first glance.
There is a contractor name.
There is a project description.
There is a price.
But the important issues are often buried in the details.
One proposal may include permits, controls, electrical work, roof patching, duct modifications, startup, commissioning, warranty registration, and closeout documents.
Another may exclude some of those items, leave them vague, or mark them “by others.”
That is where responsibility gaps appear.
If nobody identifies those gaps before award, they can become owner problems later.
What Is a Responsibility Gap?
A responsibility gap is an item required for the project that is not clearly owned by anyone in the bid package.
It may be excluded.
It may be marked “by others.”
It may be mentioned but not priced.
It may be assumed by one bidder and ignored by another.
It may be part of the project, but not clearly assigned to the HVAC contractor, owner, property manager, association, electrician, controls vendor, roofer, engineer, or another trade.
That matters because unassigned work can lead to added cost, delays, confusion, and disputes after the contractor is selected.
Why HVAC Bids Create Gaps
HVAC projects often involve more than equipment replacement.
Even a straightforward replacement may touch multiple areas of responsibility.
Examples include:
- Permits and inspections
- Controls or BAS/EMS coordination
- Electrical disconnect and reconnect work
- Ductwork modifications
- Gas piping or condensate work
- Roof curb, flashing, or patching
- Crane, lift, rigging, or equipment access
- Startup, commissioning, testing, and balancing
- Warranty registration
- Closeout documents
- After-hours access or tenant coordination
Some HVAC contractors include many of these items.
Some include only part of them.
Some exclude them entirely.
If the owner or manager only compares the bottom-line price, those responsibility differences can be missed.
“By Others” Is Not a Minor Phrase
The phrase “by others” is one of the most important phrases to watch in an HVAC proposal.
It usually means the bidder is not including that work in the quoted price.
Examples may include:
- Controls by others
- Electrical by others
- Permits by others
- Roof patching by others
- Duct modifications by others
- Crane access by others
- Structural support by others
That language does not automatically make a proposal bad.
But it does require follow-up.
The key question is:
Who is actually responsible for that work?
If another vendor has already priced it, fine.
If the owner has already planned to handle it, fine.
If nobody has accounted for it, then “by others” may point to a gap in the project.
Exclusions Can Shift Responsibility
Exclusions are not just technical details.
They can shift responsibility back to the owner, manager, board, or another contractor.
Common HVAC bid exclusions include:
- Permits
- Permit fees
- Inspections
- Controls or BAS integration
- Electrical work
- Ductwork modifications
- Roof curb work
- Crane, lift, or rigging
- Structural support
- After-hours work
- Temporary heating or cooling
- Engineering
- Bonding
- Taxes, freight, or shipping
- Warranty registration
- Startup or commissioning
- Cleanup, patching, or finish repair
An excluded item may still be necessary for the project.
If it is necessary but not included, the owner needs to know who will perform it, who will pay for it, and whether it affects schedule or warranty.
Permits and Inspections
Permit responsibility should be assigned before an HVAC contractor is chosen.
Some bids include permits and inspections.
Some exclude permits.
Some say permits are by owner or by others.
Some do not mention them at all.
Questions to ask include:
- Who applies for the permit?
- Who pays permit fees?
- Who schedules inspections?
- Who handles corrections if an inspection issue comes up?
- Is any owner or manager action required?
If the answer is unclear, the owner may be left coordinating an item that should have been resolved before award.
Controls, BAS, and EMS Coordination
Controls are a common source of responsibility gaps.
One contractor may include only basic thermostat work.
Another may include building automation or EMS coordination.
Another may exclude controls entirely.
Questions to ask include:
- Are thermostats included?
- Is control wiring included?
- Is BAS or EMS integration included?
- Is programming included?
- Is testing included?
- Is a separate controls contractor required?
- Who coordinates the controls contractor?
If controls are required but not owned by anyone in the bid package, the project may face added coordination and cost after award.
Electrical Work
Electrical work is another frequent gap.
Some HVAC bids include disconnect and reconnect work.
Some exclude electrical work.
Some require the owner to provide a separate electrician.
Before award, confirm who owns:
- Disconnecting existing equipment
- Reconnecting new equipment
- New disconnects
- Breakers
- Wiring or conduit
- Line-voltage electrical work
- Low-voltage wiring
- Coordination with an electrical contractor
If electrical work is excluded, the bid may still be usable, but the owner needs to account for the separate cost and scheduling responsibility.
Roof Work and Equipment Access
For rooftop HVAC units, roof-related work and access issues can create major responsibility gaps.
Common unclear items include:
- Roof curbs
- Curb adapters
- Flashing
- Roof patching
- Waterproofing
- Structural supports
- Crane or lift access
- Rigging
- Street, alley, or parking coordination
If roof patching is excluded from the HVAC bid, the owner may need a roofer.
If crane access is excluded, the owner may need to coordinate logistics separately.
If structural support is excluded, the owner may need an engineer or structural contractor.
Those items should be identified before the contractor is selected.
Startup, Commissioning, and Warranty
A bid may include installation but leave startup, commissioning, and warranty steps unclear.
That can create problems after the equipment is installed.
Before award, confirm who owns:
- Startup
- Factory startup, if required
- Testing and balancing
- Commissioning
- Warranty registration
- Labor warranty support
- Manufacturer warranty coordination
- Closeout documents
- Owner training
If nobody clearly owns these items, the owner may have trouble confirming that the system was properly completed and documented.
Owner Responsibilities Should Be Named
Some owner responsibilities are normal.
The problem is not that the owner has responsibilities.
The problem is when those responsibilities are hidden, vague, or discovered too late.
Potential owner responsibilities may include:
- Providing access
- Coordinating shutdowns
- Notifying tenants, residents, or occupants
- Approving added work
- Hiring a separate electrician
- Hiring a separate controls contractor
- Hiring a roofer
- Handling permits or inspections
- Paying tax, freight, permit fees, or disposal fees
- Managing hazardous materials or concealed conditions
These should be clearly identified before the bid is accepted.
What Happens When Nobody Owns the Gap
When responsibility gaps are not resolved before award, several things can happen.
- The owner pays separately for work assumed to be included.
- The contractor submits a change order.
- The project is delayed while another vendor is found.
- The manager spends extra time coordinating trades.
- The board has to approve additional cost.
- Warranty or closeout items become unclear.
- Disputes arise over what the bid was supposed to include.
Many of these problems are avoidable if responsibility is clarified before the contractor is selected.
How to Find the Gaps Before Award
The best way to find responsibility gaps is to compare the bids by scope, not just price.
Ask:
- What work is clearly included?
- What work is clearly excluded?
- What is marked “by others”?
- What is mentioned but not priced?
- What is required for the project but missing from the bid?
- What requires a separate trade or vendor?
- What does the owner or manager need to coordinate?
- What should be clarified in writing before award?
Then send direct questions back to the bidders.
For example:
- Please confirm who is responsible for permits and permit fees.
- Please confirm whether controls integration is included or by others.
- Please confirm whether electrical disconnect and reconnect work is included.
- Please clarify whether roof patching is included, excluded, or by others.
- Please confirm whether startup, commissioning, and warranty registration are included.
- Please identify any owner responsibilities not already listed in your proposal.

The Better Question
When comparing HVAC bids, it is not enough to ask:
Which contractor has the lowest price?
A better question is:
Who owns every important part of the work?
If the answer is clear, the owner can make a better-informed decision.
If the answer is unclear, the bid may need clarification before award.
That does not mean the lowest bid is wrong.
It means the decision should be based on a complete understanding of price, scope, exclusions, and responsibility.
