Signs that your air conditioner needs maintenance
Reduced cooling performance
- If you notice that your air conditioner is not cooling your home as effectively as it used to or if there are hot spots in certain areas, it may indicate that your air conditioner needs attention.
Increased energy bills
- A sudden spike in your energy bills without a change in your cooling habits could be a sign that your air conditioner is not running efficiently.
Unusual noises
- Strange noises such as grinding, rattling, or squealing coming from your AC unit may indicate that there are loose or damaged components that need attention.
Weak airflow
- If the airflow from your vents feels weak or is not consistent, it could be due to clogged filters, blocked ducts, or issues with the blower motor.
Foul odours
- Persistent musty or foul odours when your AC is running might be a sign of mould or mildew buildup in the system, which requires cleaning and maintenance.
Frequent on and off cycling
- If your air conditioner is turning on and off more frequently than usual, it could be a sign of a malfunctioning thermostat or other internal issues.
Water leaks
- Puddles of water or excessive condensation around your AC unit might indicate a clogged condensate drain or other drainage issues.
Unpleasant smells
- Burning or pungent smells coming from your AC could indicate overheating or electrical problems that require immediate maintenance.
Age of AC unit
- If your air conditioner is older and hasn’t received regular maintenance, it’s more susceptible to problems and may benefit from a thorough inspection and tune-up.
Air Conditioner cleaning and maintenance tasks
Safety first! Before you start any repair, make sure you disconnect your appliance from the power source. An air conditioner is an electrical appliance that needs to be treated with extreme care.
Inspect and clean the filters
One of the easiest and most crucial tasks in spring Air Conditioning maintenance is cleaning or replacing your air filters. Over time, dust and debris accumulate in the filters, reducing airflow and making your air conditioner work harder than it needs to. To clean your filters:
Step 1: Turn off the air conditioner
Before cleaning the air filters, make sure the AC unit is turned off to ensure safety.
Step 2: Locate the air filters
Air filters are usually located near the return air duct or in the indoor unit of the air conditioner.
Step 3: Remove the filters
Gently slide out the filters from their slots. Be careful not to damage the filter or surrounding components.
Step 4: Check for debris and wash the filters
Inspect the filters for dust, dirt, and debris buildup. Use a vacuum cleaner or a soft brush to remove dust and debris. If the filters are washable, rinse the filters under running water to remove the dirt. You can use mild detergent for stubborn stains.
Handy hint! Use a Quick Clean Kit to easily remove dust and debris and clean hard-to-reach nooks. This kit can be used for all makes and model of air conditioners.
Step 5: Let them dry
Shake off excess water and allow the filters to air dry completely before reinstalling them.
Step 6: Reinstall the filters
Slide the clean and dry filters back into their slots securely.
Check the outdoor unit
Throughout the winter, your outdoor unit may have gathered leaves, dirt, and other debris. Make sure it’s clear of any obstructions and wipe it down with a damp cloth. While you’re at it, inspect the unit for any signs of damage or wear. Check if the fan blades are in good condition and not bent. If you notice any issues or suspect that air conditioner spare parts are required, it’s best to call a professional HVAC technician for a thorough inspection and repairs.
Test your thermostat
Spring is an excellent time to test your thermostat and ensure it’s functioning correctly. Turn on the air conditioner and set the thermostat to a temperature lower than the room temperature. You should hear a click sound, indicating that the thermostat is signalling the AC unit to start cooling. Allow the AC to run for a few minutes and monitor if the temperature drops as expected. If the AC doesn’t respond to the thermostat’s settings, it could indicate a problem with the thermostat. You can replace the thermostat if needed.
Clean the coils
The coils in your air conditioner play a crucial role in the cooling process. Over time, they can get covered in dirt and grime, hindering their efficiency. Use a soft brush or a vacuum cleaner with a brush attachment to gently remove any visible dirt, dust, or debris from the coils and surrounding areas. Be careful not to bend the delicate fins. Air conditioner coils can be cleaned using a simple solution of mild household detergent and water. Firstly, ensure the power to your AC unit is switched off. Apply the mix with a low-pressure sprayer on the coils, and let it drain or rinse lightly with a garden hose.
Seal the leaks
Air leaks in your ductwork can lead to energy wastage and reduced cooling efficiency. During your spring HVAC maintenance, take some time to inspect your ductwork for leaks. Run your hand along the seams and joints to feel for any escaping air. Seal the leaks with duct mastic or metal tape, as regular duct tape won’t hold up over time. This DIY repair can significantly improve your system’s efficiency and keep your home cooler without overworking your AC.
Lubricate moving parts
Lubricate moving parts, such as fan motors and bearings, to reduce friction and maintain smooth operation.
Adjust the temperature for the warmer season
Set the right temperature for your comfort and energy efficiency. While it may be tempting to turn the AC down to the lowest setting during heatwaves, doing so can strain your system and lead to higher energy bills. Instead, aim for a comfortable temperature between (22-26°C). Using a programmable thermostat allows you to adjust the temperature based on your schedule, saving energy when you’re not at home.
