If you live in Johor Bahru, you know what heatwave season actually feels like. Temperatures crossing 35°C, humidity that doesn’t drop even at night, and concrete buildings that absorb heat all day and slowly release it while you’re trying to sleep. During these weeks, your aircond isn’t a comfort appliance anymore. It’s the only thing standing between you and a genuinely miserable home.
The problem is that most airconds in JB homes are running on outdated filters, low gas, or components that haven’t been checked in months. Normal days hide those issues. Peak heat exposes every single one of them, usually at 2pm on the hottest day of the year, when you need the system most.
That’s where we come in. Rahima Aircond Services handles aircond cleaning, gas refills, repairs, and maintenance for homes and businesses across JB. Fast response, upfront pricing, and SSM-registered technicians who know Johor Bahru’s heat conditions inside out.
Your aircond doesn’t produce cold air. It removes heat from inside your home and dumps it outside. That works well when outdoor temperatures are moderate. When JB hits 35°C or higher, the outdoor unit has to push heat into air that’s already hot, and that gets harder the longer it runs.
The compressor works overtime. Pressure inside the system climbs. Electrical components draw more power. If your filters are clogged, your gas is low, or your outdoor unit has no airflow because it’s boxed in on a narrow balcony, that extra strain turns a slow system into a broken one fast.
Most of these problems are preventable. A proper service before peak heat catches them early, before they become emergency repairs booked mid-heatwave, when every aircond technician in JB is fully booked and parts take longer to source.
These are the issues our technicians see again and again once peak heat kicks in:
Weak or warm airflow. Usually a dirty filter or clogged evaporator coils. The system is running but heat transfer is blocked. Longer run times, higher bills, and your room never quite cools down.
AC blowing air but not cold. Low refrigerant, almost always from a leak. Topping up gas without fixing the leak just delays the problem. Our technicians check pressure, find the leak, fix it, then refill properly.
Water leaking from the indoor unit. During heatwave season, your aircond removes more moisture from the air. If the drainage pipe is even partially blocked, that water backs up fast. It’s one of the most common callouts we get in JB between May and August.
Compressor shutting down mid-afternoon. The outdoor unit overheats when ambient temperatures are high and airflow around it is restricted. If your unit is on a tight balcony or near a wall with no clearance, this will happen under enough heat load.
Tripping the circuit breaker. Electrical components under sustained load, especially capacitors and wiring in older units, can fail or overheat. This is the kind of problem that gives no warning before it becomes a safety issue.
Don’t wait for a full breakdown. These are the warnings your system is giving you:
Rahima Aircond Services covers everything your unit needs before and during heatwave season. Pricing is upfront. No hidden charges.
Filter and indoor unit cleaning, cooling check. For units with weak airflow, dust smell, or water leakage. Best first step before peak heat.
Pressure and leak check, plus gas top-up. For ACs that blow air but stay warm. We fix the leak before refilling so it lasts.
Deep clean of coils and internal parts. Removes stubborn dirt, grease, and mold. Restores proper cooling and airflow in units that regular cleaning can’t fix.
Compressor, fan, sensor, motor, PCB, and parts replacement. Same-day repair available. For ACs making noise, tripping, or not turning on.
Quarterly inspection, cleaning, performance check, and priority scheduling. Best value for AC owners who want zero heatwave surprises.
Mounting, piping up to 10ft, wiring, and test run. 30-day warranty included. For new setups or relocating your existing unit.

Areas we cover:
If your booking is scheduled but a few days away, a few simple habits reduce the load on your unit in the meantime:
Close curtains or blinds during the day, especially on sun-facing windows. Direct sunlight through glass adds significant heat load to any room. Blocking it gives your aircond a real advantage.
Check the filters yourself if you can access them safely. If they’re visibly grey or dusty, rinse them gently with water, let them dry fully, and put them back. It takes 10 minutes and makes a meaningful difference in airflow until our technician arrives for the proper service.
Don’t run large heat-generating appliances like ovens or dryers during the hottest hours of the day. That additional heat load goes straight into the same rooms your aircond is trying to cool.
These habits buy you some comfort and reduce strain. They’re not a substitute for fixing a gas leak, cleaning blocked coils, or addressing failing electrical components. For that, you need a proper service.
Every six months is the standard recommendation for most households. If your unit runs heavily every day, or if you’re heading into peak heat with a unit that hasn’t been serviced in over a year, book one now. An additional pre-season check makes a real difference.
Yes, as long as the unit has been properly serviced and you’re running it at a sensible temperature like 24°C–26°C. A well-maintained aircond handles long run times fine. An unmaintained one running non-stop is where the risk of breakdown comes in.
Your unit removes more moisture from the air during heatwave conditions, which means more condensation. If the drainage pipe is even slightly blocked, that extra water has nowhere to go. We flush the drain line during every service, which is one of the simplest and most effective things we do.
It can be. A system low on refrigerant or with a dirty coil sometimes produces cold but damp air because it’s not dehumidifying properly. Johor Bahru’s humidity makes this more noticeable. A service check will tell you whether it’s a maintenance issue or something that needs a gas refill.
