Commercial
If you own commercial property that you let to business tenants, the air conditioning in those units is more your concern than you might like it to be. It is an asset you own. It is a system that carries legal duties. It is a frequent source of friction with tenants. Handled well it quietly supports the value of the building and keeps occupiers happy. Handled badly it turns into breakdown calls disputes and an unexpected bill at the worst possible moment.
Air Con North has looked after commercial air conditioning for landlords across the North-East of England for more than 25 years, from single let shops in town centres through to multi-unit industrial estates around Gateshead Sunderland and Middlesbrough. This guide sets out what you need to know as the owner rather than the occupier, in plain terms and without the jargon.
What you are actually responsible for
The split of responsibility for air conditioning in a let unit is driven by the lease. There are duties attached to the equipment itself that follow ownership and operation regardless of what the lease says. As a rule the fabric of the building and the plant that serves it tend to sit with the landlord, while day-to-day comfort settings sit with the tenant. The detail is where disputes start, so it pays to be clear from the outset rather than after something has already gone wrong.
Whatever the lease says, you cannot simply forget the plant exists. A refrigerant system is regulated equipment. Letting it run untended until it fails is both a false economy and, in parts, a breach of your duties. The sensible position is to know exactly what plant is on your property, what condition it is in and who is keeping it maintained. That knowledge costs very little to gather. It saves a great deal of argument later on.
There is a practical point hidden in all of this. The person who installed the system is often long gone, the paperwork has been lost in a handover and nobody on either side is quite sure what model is on the roof or when it last had a proper look. A quick survey settles all of that. We walk the units, note what is installed, check the condition and give you a plain written picture of where each system stands. For a landlord taking on a building or inheriting a managing agent’s loose ends, that baseline is worth having before the first summer puts the plant to the test.
F-Gas and maintenance duties
Air conditioning runs on fluorinated refrigerant gases. The F-Gas regulations place real obligations on whoever operates the equipment. Systems above certain charge thresholds must have regular leak checks by qualified engineers. Records must be kept. Any recovered refrigerant must be handled correctly at end of life. These are not optional good-practice suggestions. They are legal requirements with penalties attached to them.
The question of who the operator is in a landlord and tenant relationship is one worth settling clearly, because the duty can sit with either party depending on who has real control of the equipment. Our advice is to make it explicit in writing rather than leave it to be argued over after a problem. Whoever carries the duty, Air Con North can hold the leak-check schedule and the records so that the obligation is genuinely met. The alternative is both sides assuming the other has done it until the day neither has.
Who maintains what in a lease
The cleanest arrangements we see are the ones where maintenance is defined in plain terms before anyone moves in. There are really three common patterns and each has its place.
- Landlord-held plant. In many leases the landlord retains the main plant and recovers maintenance costs through a service charge. This keeps the equipment under one consistent maintenance regime, which protects your asset and avoids a patchwork of tenant-arranged quick fixes.
- Tenant-maintained units. In others the tenant takes on maintenance of the unit serving their demise. This can work fine. You do want evidence that it is actually being done though, because a neglected unit handed back at lease end becomes your problem to put right.
- Shared systems. Where one system serves several demises the responsibility almost always has to sit with the landlord, because no single tenant can sensibly maintain plant they share with their neighbours.
Whichever route you choose, the key is proof. A maintenance regime you can demonstrate protects you at rent review at lease end and in any dispute about condition. An empty folder protects nobody.
Multi-let estates and shared plant
Estates with several units under one roof bring their own headaches. A single system might serve two or three demises. A shared plant room might feed the lot. Common parts such as a reception or a stairwell need conditioning that no individual tenant should be asked to look after. In these buildings a scattered approach quickly turns into finger-pointing, with each tenant blaming the next for a system nobody is clearly responsible for.
The clean answer is to pull the shared and common plant under a single landlord-held maintenance regime recovered fairly through the service charge. One contractor looks after the whole site. One record covers every system. When a fault appears there is no argument about whose job it is to fix it, which matters most on the hottest day of the year when tempers are already short. We are set up to look after multi-let estates this way across the North-East, keeping one picture of every unit on the site rather than a drawer full of unrelated call-out sheets.
EPC MEES and efficiency
Energy efficiency is no longer just a running-cost matter for the tenant. Minimum Energy Efficiency Standards mean a commercial property has to meet a minimum EPC rating before it can be let. Those standards have been tightening over time. Old inefficient air conditioning drags an EPC down. A poor rating can leave a unit legally unlettable, which is about the worst position a commercial landlord can be in.
This changes the calculation on ageing plant. Replacing tired fixed-speed kit with modern inverter or VRF equipment is not only cheaper to run for the tenant. It can be the thing that lifts a unit over the threshold and keeps it lettable. We assess the existing systems in your portfolio and tell you honestly which are dragging their units down and which have life left in them. That way any spend is aimed where it actually improves lettability rather than being scattered about for the sake of it.
End-of-life replacement
Air conditioning does not last forever. The end tends to arrive inconveniently. A unit that limps through one summer often fails in the next, usually when a tenant most needs it and least wants to hear that there is a wait for parts. Planning replacement before that point is far better than reacting to a breakdown with an unhappy occupier on the phone.
There is a regulatory nudge here too. Older systems run on refrigerants that are being phased down, which makes repairs harder and the gas dearer and scarcer as time goes on. A system built around an obsolete refrigerant is on borrowed time whatever its mechanical condition. We flag these in a portfolio review so you can budget for an orderly replacement rather than an emergency one. Where possible we schedule the work for a void period or a quiet season. An orderly replacement is always the cheaper replacement.
Keeping tenants happy
A tenant with reliable comfortable premises renews. A tenant who spends every summer complaining about a unit that cannot cope starts looking elsewhere. A void costs you far more than a service contract ever would. Air conditioning is one of the most common sources of occupier grievance. It is also one of the easiest to get right.
Responsiveness matters as much as the kit itself. When something does go wrong a tenant wants it dealt with quickly. A landlord who has a maintenance contract already in place with a local engineer looks a great deal better than one scrambling to find somebody who can attend. Having Air Con North on call for your properties means your tenants get a fast knowledgeable response. You get a single point of contact who already knows the buildings and does not need the history explained every time.
Record-keeping
Good records are a landlord’s best friend. You want to be able to show, at any moment, what plant is on each property, when it was last serviced, when its leak checks fell due and what condition it is in. That record protects you in F-Gas terms. It supports your EPC position. It settles dilapidations arguments at lease end. It makes the property easier to value and sell when the time comes.
We keep this information for the landlords we work with as part of the maintenance arrangement, so that the history of every system is there when you need it rather than scattered across old invoices and half-remembered visits from engineers who have long since moved on. When a buyer or a surveyor asks the question, you have the answer ready in front of you.
Service charges and recovering costs
Where the plant is landlord-held, the maintenance is usually recovered through the service charge. Tenants are far more willing to pay a service charge they can see the value in, so a planned maintenance regime with clear records is as much about tenant relations as it is about the kit. A vague charge with nothing to show for it breeds resentment. A charge that visibly keeps the systems reliable and compliant rarely gets argued over at all.
It pays to think about how costs fall across a tenancy. Routine servicing and leak checks are ongoing running costs that sit naturally within a service charge. A full system replacement is a different matter, often falling closer to the landlord as an improvement to the building rather than a day-to-day cost. Getting this split clear in the lease and in the way the charge is presented avoids a dispute later. We lay out maintenance and any recommended replacement separately in our reports, so you can see plainly what is a running cost and what is a capital decision. That clarity makes the service charge easier to justify and the budgeting easier to plan.
Planning works around your tenants
A tenant running a business does not want engineers under their feet during trading hours, so the timing of any work matters almost as much as the work itself. Routine servicing can usually be slotted into quiet periods with a little notice. Larger jobs such as a replacement are best planned around the tenant rather than sprung on them, ideally in a void between lettings or a naturally quiet season for that business.
A landlord who handles this well keeps a good relationship with occupiers who might otherwise dread the sight of a van in the car park. We coordinate access directly with your tenants where you would like us to, keeping you informed without you having to play messenger between the two sides. Good communication here does more for tenant goodwill than people expect. Goodwill is what quietly turns into a renewal when the lease comes up.
