Portable Air Conditioning and Social Housing: Who Owns the Risk?
Portable air conditioning is becoming increasingly common in residential properties.
For residents living in homes that become uncomfortably hot during periods of extreme weather, a portable AC unit can provide an immediate and very welcome solution.
But for social housing providers, there is a question that deserves more attention:
Who owns the risk when a resident introduces a portable air-conditioning unit into a home?
I’m not talking about who owns the appliance.
I’m talking about who understands and manages the consequences of its use.
A resident buys an AC unit. What happens next?
Imagine a resident purchases a portable air conditioner from a well-known retailer.
They haven’t modified the ventilation system.
They haven’t altered the electrical installation.
They’ve simply purchased a domestic appliance and followed the manufacturer’s instructions.
But the appliance may be moving a substantial volume of air through the property.
A single-hose portable AC takes air from the dwelling and exhausts it outside.
That means replacement air has to enter the property.
Depending on the building, that air could come through windows, trickle vents, door gaps, ventilation openings or other leakage paths.
The resident may simply see a cooler room.
The building may be experiencing a significant change in its airflow and pressure conditions.
And that’s where the responsibility question gets interesting.
Suppose the property already has mechanical ventilation.
The landlord is responsible for maintaining that ventilation system.
The resident then starts operating a portable AC.
If problems subsequently occur, the resident may report:
- inadequate ventilation
- condensation
- increased humidity
- uncomfortable air movement
- noise
- or even damp and mould.
Who investigates?
And perhaps more importantly:
Who understands the interaction between the two systems?
It would be easy to say:
“The resident bought the AC, so it’s their responsibility.”
But is that always sufficient?
The landlord still owns and maintains the dwelling and its ventilation system.
The resident may have done nothing unreasonable.
And if the use of portable air conditioning is now a reasonably foreseeable response to increasingly frequent overheating, perhaps simply saying “that’s not our equipment” isn’t enough.
I’m not suggesting that landlords automatically become responsible.
That’s an important distinction.
A housing provider cannot reasonably be expected to take responsibility for every domestic appliance a resident purchases.
Nor does the introduction of a portable AC automatically make the landlord responsible for any subsequent problem.
But there is a difference between being responsible for the appliance and understanding how the appliance interacts with the home.
That distinction is important.
Perhaps the real issue is risk management.
Housing providers already consider the interaction between:
Heating + insulation + ventilation + moisture + occupancy
Perhaps cooling needs to be added to that equation.
If portable AC is becoming an increasingly common response to overheating, providers should consider whether their policies and procedures adequately address it.
For example:
Do we provide residents with guidance on using portable AC?
Do we explain how single-hose systems interact with ventilation?
Do our repairs teams know what questions to ask when investigating a complaint?
Do our ventilation contractors understand the potential interaction?
Do our overheating assessments consider how residents are likely to respond during extreme heat?
And perhaps most importantly:
Have we decided where responsibility sits before there is a problem?
This is particularly important in the context of healthy homes.
We rightly focus on damp and mould.
We rightly focus on ventilation.
We increasingly focus on overheating.
But residents don’t experience these as separate compliance categories.
They experience them as:
“Is my home healthy and comfortable to live in?”
A resident experiencing overheating may close windows because of noise or security concerns.
They may purchase a portable AC.
They may use it alongside an existing extract fan or mechanical ventilation system.
They may make decisions that make perfect sense from their perspective.
Our buildings must accommodate real-life behaviour.
So who owns the risk?
Perhaps the answer isn’t simply:
The landlord.
Or:
The resident.
Perhaps the answer is:
The risk needs to be understood by both.
The resident needs clear information about how to use equipment safely and effectively.
The landlord needs to understand the ventilation and building implications.
Contractors need to recognise when a complaint may involve an interaction between systems rather than a straightforward equipment fault.
And housing providers need a clear policy for dealing with situations where residents introduce equipment that can affect the building’s performance.
The question I’d ask housing providers is this:
If a resident in one of your properties buys a portable air conditioner tomorrow, do you know what you would tell them?
If the answer is “we haven’t really considered it”, perhaps now is the time.
Because the use of portable air conditioning isn’t going away.
And just as we have learned that ventilation, damp, mould and overheating cannot always be considered in isolation, we may need to recognise that resident-installed cooling equipment is becoming part of the way our homes actually operate.
The question isn’t simply:
“Who owns the AC?”
It’s:
“Who owns the risk?”
And, perhaps more importantly:
“Have we understood the risk well enough to manage it?”
