You arrive at your Kenton-on-Sea house, switch on the aircon and nothing happens. Or it runs but blows warm air. It is a common story for holiday homes, and it is usually fixable. Here is what to check, why it happens and how to stop it happening next year.
Holiday-home aircons in Kenton often fail because months of salty, humid air corrode connections, capacitors weaken, insects nest in the outdoor unit, drains dry out and block, and power surges damage boards while nobody is home. Check the isolator, breaker, remote and filters first. To prevent it, have the unit run monthly, use surge protection and book a pre-holiday service.
First checks when you arrive
Before calling anyone, work through these quick checks. They solve a surprising number of holiday-home aircon problems.
1. Power
- Is the isolator switch next to the outdoor unit or indoor unit switched on? Caretakers and cleaners sometimes switch these off.
- Has the circuit breaker for the aircon tripped at the distribution board?
- Is the earth leakage tripped? If it trips again as soon as you switch the aircon on, leave it off and call a technician.
2. Remote
- Are the batteries flat? Remote batteries often die over a long absence.
- Is it set to cool mode (snowflake symbol)?
- Is the temperature set below the room temperature?
3. Filters
Open the front cover and check the filters. Dust and sometimes insects collect on them while the unit stands. Rinse, dry and refit.
4. Outdoor unit
- Is anything blocking it: sand, leaves, a nest, garden furniture?
- When the unit is on, does the outdoor fan spin? Do you hear the compressor?
If the power is on, the remote works, the filters are clean and the unit still does not start or cool, it is time to call a technician.
Why idle aircons fail
Corrosion of connections
Kenton sits between two river mouths and the sea. Salt and humidity get into the outdoor unit's electrical compartment and corrode terminals and wires. A corroded connection can stop the compressor or fan from getting power, or cause overheating.
Weak capacitors
Capacitors store electrical energy to start the compressor and fan motors. They age whether the unit is used or not. After months of standing, a weak capacitor may not deliver enough to start the compressor, especially on the first hot day.
Insects and small animals
Ants, wasps, beetles and geckos like the shelter of an idle outdoor unit. Ant nests in the electrical compartment can cause short circuits. Wasp nests can jam fans. Insects can also block drain lines.
Dried-out drains
When an aircon runs, water flows through the drain line. When it stands unused, any slime in the line dries into a crust. The first time the unit runs again, the crust blocks the flow and water drips from the indoor unit.
Power surges
When electricity returns after an outage, there can be a spike. If nobody is there to switch off the aircon, the spike can damage the control board, sensors or capacitors. Holiday homes are especially exposed because outages often go unnoticed for days.
Slow gas leaks
Salt corrosion on the coil and joints creates tiny leaks. Over months, enough gas escapes that the unit no longer cools.
Getting it fixed quickly
Kenton is a longer trip from Gqeberha, and holiday periods are busy, so help us help you:
- Send a WhatsApp describing what happens when you switch the unit on.
- Include photos of the indoor unit, the outdoor unit and both model stickers.
- Note any error codes or flashing lights.
- Tell us what you have already checked.
With this information, we can often identify the likely fault and bring the right parts, so the repair is done in one visit.
Preventing it next year
Run it monthly
Ask a caretaker, cleaner or neighbour to run each aircon for 20 to 30 minutes once a month in cooling mode. This keeps components moving, keeps the drain wet and shows up problems early.
Protect against surges
Install surge protection at the distribution board, or switch the aircon off at the isolator when you leave, and switch it back on a day before you return.
Keep the outdoor unit clean
Rinse it gently with fresh water a few times a year, and keep sand, leaves and garden growth away from it.
Book a pre-holiday service
A service in October or November covers cleaning, gas checks, capacitor testing, electrical checks and a look for insects and corrosion. Anything found can be fixed before you arrive.
Consider Wi-Fi control
Some units can be monitored and controlled from your phone. You can switch them on remotely to test them before you travel, and switch them off if guests forget.
Bushmans River Mouth, Boknes and Cannon Rocks
Everything above applies equally to Bushmans River Mouth, Boknes and Cannon Rocks. Homes closest to the sea or river mouths see the most corrosion, so regular rinsing and servicing matter even more there.
Frequently asked questions
My aircon trips the power as soon as I switch it on. What should I do?
Leave it off and call a technician. Repeated tripping usually means an electrical fault, such as a damaged compressor, moisture in the wiring or a short caused by insects.
Can a caretaker do the monthly run for me?
Yes. Show them how to switch the unit on in cooling mode, let it run for 20 to 30 minutes with doors closed, and ask them to report any noises, leaks or error codes.
Should I switch the aircon off at the isolator when I leave?
If you do not have surge protection, it is a sensible precaution. Just remember to switch it back on and test it a day before you need it.
