Even the best air conditioning systems can run into trouble from time to time—especially in Lanzarote’s harsh coastal climate. Here are some of the most common issues we come across, what causes them, and how they can be avoided.
The problem:
Water dripping from the indoor unit, running down the wall, or even forming puddles on the floor.
Common causes:
Prevention:
Regular maintenance. Most water leaks are easy to avoid if the system is cleaned and checked once or twice a year.
The problem:
The unit is running but the room never seems to reach the right temperature.
Common causes:
Prevention:
Keep the filters clean, and make sure the system is serviced regularly. If the system was never sized properly in the first place, that may need to be addressed too.
The problem:
Strange rattling, buzzing, or humming from the indoor or outdoor unit.
Common causes:
Prevention:
A routine inspection can often catch these before they become serious. If something suddenly sounds off, switch it off and get it checked.
The problem:
The system won’t start at all.
Common causes:
Prevention:
Check the basics first (fuses, power, remote batteries). If everything looks fine, it’ll likely need a technician to diagnose properly.
The problem:
The evaporator coil is frozen over, sometimes with ice dripping when it melts.
Common causes:
Prevention:
Keep filters clean and windows shut when the unit is on. If it ices up regularly, stop using it and call for a service—it’s only going to get worse.
The problem:
A burning smell when the unit starts or runs.
Common causes:
Prevention:
Always investigate burning smells. If it’s more than a quick puff of dust, switch it off and get it looked at—especially if it smells like burning plastic or wires.
The problem:
Short cycling—where the system runs for a short time, turns off, then starts again quickly.
Common causes:
Prevention:
Aside from maintenance, short cycling is often a sign the system is too big for the space. This can reduce efficiency and wear the system out faster.
The vast majority of problems we see could have been avoided with regular maintenance. Even something as simple as a dirty filter can lead to leaks, poor performance, or system failure.
If your system’s showing signs of any of the issues above, or you just want peace of mind, get in touch—we’re happy to inspect it and keep it running right.
