Air conditioning can be a literal lifesaver in climates with scorching hot summers. However, many homeowners are inadvertently reducing the efficiency and lifespan of their units. Negative Maintenance Habits can cause expensive service calls, increased energy bills or the need for early replacement of your system. So, to help keep from making the same mistakes, here is a list of common aircon maintenance mistakes, with some practical advice on how to make sure yours runs smoothly for years to come.
1. Failing to Get Scheduled Professional Servicing
One of the costliest is failing to schedule professional air conditioner service. While DIY cleaning may alleviate some of the dust and dirt from your coils and connections, only qualified technicians can examine and service your refrigerant levels and do the dirty work inside your compressor. Dust buildup over time, refrigerant leaks, or worn-out parts can stress the system, causing malfunctions.
Plan regular maintenance with a reliable contractor such as air conditioner service to keep your unit running effectively. Their team can catch problems early, saving you a lot of money in the long haul.
2. Failing to Clean Air Filters or Replace When Necessary
Clogged air filters restrict airflow and make the unit work harder. This not only uses more energy but may also frost the evaporator coil or cause the compressor to overheat. Filters need to be cleaned/changed as per the usage (every 2- 4 Weeks or 4-8 Weeks). Do not Clean with Soap and Water.
Pro Tip: “Use your cell phone to remind yourself to check filters once a month. Because it will streamline airflow and eliminate 80% of typical performance problems.
3. Adjusting the Thermostat Too Low
Turning the thermostat to 18°C does not cool the room faster—it just means more work for the compressor. Rapid switches between freezing and burning are hard on the system and can boost electricity bills. Instead, use the rule of 23–25°C for a good balance between comfort and efficiency.
If you, too, have one of those units that have difficulty keeping the room at temperature, it may signal deeper problems such as refrigerant leaks or duct issues. Here’s a guide on air conditioner electrical faults to give you a start on troubleshooting.
4. Obstructing Vents or Rooftop Units
Restricted air flow will cause your air conditioner to work harder.
Vents become blocked, and airflow is not uniform, resulting in inconsistent cooling and pressure differences. Keep furniture, curtains, and stuff away from indoor vents. The outdoor unit alone requires at least 2 feet of clearance to dissipate heat. Cut the plants off, sweep away the debris, and clean the mess every once in a while.
Warning: A misclogged outdoor unit can decrease efficiency by 15% and result in compressor failure.
5. Strange Sounds or Leaks Are Overlooked
Sound and water leakage are also rare signs of the problem. Leaking refrigerant may be bad for the environment and your health, while water leaks could mean a drain pipe is clogged. Allowing these problems to continue unnoticed can cause irreversible harm.
Please inform an air conditioner service expert as soon as you see or experience these things. Prompt attention now can save on repair bills later.
6. DIYing the Damage without knowing what you’re doing
Changing Filters Is Safe This is indeed correct, but it is important not to fiddle with things like electrical elements and refrigerant all by yourself because you are no technician. I’ve done that sort of thing many times before, and it’s not terribly hard, but one wrong move, and it’s bye-bye warranty, damaged rig, or even fire. In the case of more complex problems (wiring problems, gas leaks), you should always seek help from a qualified technician.
7. Neglecting the Outdoor Unit
The outside unit receives dirt, leaves, and weather conditions. Gradually, debris may block the coils or fan blades, diminishing the efficiency of heat exchange. Rinse the unit lightly every few months and have it professionally cleaned once a year.
8. Overworking the Unit
Leaving your air conditioner on 24/7 causes more wear and tear. 4) Use rotating ceiling fans to distribute cool air, keep the curtains closed during the day, and block air leaks around windows/doors to decrease the air conditioning load. For bigger houses, look at zoning systems that only cool the rooms in use.
FAQs about Aircon Maintenance Mistakes
1. How often should I clean the filters?
At least once a month during peak use. Homes with pets or allergies might need every 2 weeks.
2. Why does my aircon smell like a gym sock?
That’s mold in the evaporator coil or drain pan. A professional deep clean will fix it.
3. Can I use a pressure washer on the outdoor unit?
No! High pressure bends the delicate fins. Use a garden hose in a gentle setting.
4. What’s the ideal humidity level for my home?
Aim for 30–50%. Too much moisture strains the aircon and encourages mold.
5. How do I know if my refrigerant is low?
Signs include warm air, hissing noises, or ice on the coils. Only a technician can safely recharge it.
6. Is car AC maintenance similar?
Absolutely! Regular car service aircond checks prevent breakdowns. Refrigerant leaks and clogged filters are common issues.
7. My energy bill spiked—could it be the aircon?
Yes. Dirty coils, old units, or duct leaks can double your costs. A professional inspection can pinpoint the issue.
8. How long should an aircon last?
With proper care, 10–15 years. Neglect can halve that.
