Why tenant habits matter more than many landlords think
Most aircon faults do not start as major breakdowns. They start with small habits, like blocked filters, closed vents, warm outside units or units left running with doors wide open. In rental homes and business units, those habits quickly lead to poor cooling, higher power use and avoidable service calls.
For landlords, the cost is not just the repair bill. It is the tenant complaint, the lost time chasing access, and the wear on a unit that should have lasted longer. In hot places like Mbombela, White River, Hazyview, Klerksdorp and Potchefstroom, aircon often works harder than people realise. If the basic rules are clear from the start, the system stays cleaner and the tenant gets better comfort for longer.
The first rules to explain when keys are handed over
Tenants do not always know what an air-conditioner can and cannot handle. A short handover note or house rule sheet helps a lot. It should say who to call, what not to do, and which jobs are the tenant's responsibility versus the landlord's maintenance plan.
- Keep doors and windows closed when the unit is running.
- Do not block the indoor unit with curtains, cupboards or high furniture.
- Switch the unit off before cleaning around it.
- Report leaks, strange smells or weak cooling early.
- Never open the covers or tamper with wiring or gas lines.
- Keep the remote control in one place so settings are not changed by mistake.
These are simple points but they stop a lot of call-outs. A unit that is being used correctly will normally need less attention and fewer emergency visits.
What tenants can clean and what should stay with the installer
Some parts of aircon care are safe for tenants, while others need a trained technician. That line should be clear. If people try to do too much themselves, a small issue can turn into a bigger repair.
Tenants can usually help by keeping the indoor area dust-free and checking that the airflow is not blocked. They should also keep the outside unit clear of leaves, grass cuttings, packing boxes and laundry. In coastal or humid areas, dust mixes with moisture and forms grime very quickly. In the Lowveld, that can build up fast in summer, so regular cleaning matters.
- Safe for tenants: wiping the outside of the casing, dusting around the unit, keeping filters clean if the landlord has shown them how.
- Best for a technician: gas top-ups, electrical fault finding, deep cleaning, drain clearing where panels must be opened, and any work on pipes or wiring.
- Not allowed: bypassing switches, altering settings inside the unit, or moving the unit without approval.
A good rule is this: if a cover has to come off, the tenant should stop there and call for service.
How landlords can reduce call-outs during peak heat and load-shedding
Summer is when aircon problems get noticed fastest. It is also when call-out rates rise because units are pushed harder and people expect instant cooling. In rented homes, load-shedding makes things worse because units are switched on and off more often, then asked to cool a room that has already heated up.
Landlords can reduce complaints by putting a simple maintenance cycle in place. Scheduled servicing before the hottest months is cheaper than waiting for a no-cooling complaint in January. If the unit serves a tenant space or a small office, it is worth checking filters, drain lines, thermostat settings and outside clearances before peak season.
- Service units before summer starts.
- Check that the outside unit has proper airflow.
- Confirm the tenant knows the correct set temperature.
- Replace old remote batteries before they fail.
- Inspect for signs of water dripping inside or stained walls.
If a tenant says the unit only works sometimes, do not assume it is a user error. Intermittent faults often get worse if left too long.
A practical example from a rental property in Mbombela
At a rental in Mbombela, the tenant kept saying the bedroom unit was weak. The landlord first thought the system was undersized, but the real problem was simpler. The filters were full of dust, the outside unit was tucked against a wall with very little air movement, and the tenant had been leaving the sliding door open at night because of the heat.
After the filters were cleaned, the outside clear space improved and the tenant was shown the correct way to use the unit, the cooling improved straight away. No gas top-up was needed and no parts had to be replaced. That is the kind of avoidable expense many landlords face when tenants are not given clear usage rules from day one.
In places like Hazyview and Rustenburg, where dust and heat can be harsh, even a small change in habits can save a landlord from a costly visit. It is practical management, not guesswork.
When a small fault should be reported straight away
Some tenants wait too long because they think the problem will clear up by itself. With aircon, delays usually make things worse. A blocked drain can stain ceilings. A loose electrical connection can trip the unit. A weak fan or low gas charge can overwork the system until a bigger failure happens.
Ask tenants to report these signs as soon as they notice them:
- Water dripping from the indoor unit
- Bad smell when the aircon starts
- Loud rattling, clicking or vibration
- Little or no cool air from the vents
- The unit trips the power or refuses to restart
- Ice forming on the pipes or indoor coil
The faster the fault is checked, the more likely it is to stay a simple repair instead of a full replacement. That saves money and avoids tenant frustration.
Simple tenant rules that protect the owner’s investment
A landlord does not need a complicated manual. A one-page set of rules is enough if it is written in plain language and handed over at occupation. It should say how to use the unit, who may touch it, and when servicing is scheduled. If the property has more than one unit, list each room or area so no one is guessing which remote belongs where.
For commercial rentals in Klerksdorp or Potchefstroom, it also helps to assign responsibility for after-hours switching and filter checks. That keeps the system running as it should and avoids blame when the building gets busy.
Good aircon care is mostly about clear instruction, regular servicing and quick reporting. When tenants know the rules, landlords get fewer call-outs and better long-term value from the system.
