Air Conditioner Repair Checklist. Airconditioning units keep the atmosphere of homes and offices pleasant. When it is hot and humid, it provides cool air and refreshes the room. Since it is often in demand, air conditioner units require cleaning and maintenance.
But since it is an electronic machine, it will break down at some point. Aircon repair needs professional help like skilled technicians. However, it’s good to understand how it works.
It is to evaluate if the repairman’s assessments are reasonable or not. Where should you start? We have for you here an airconditioner repair checklist for reference! Read on!
Air Conditioner Repair Checklist
The air conditioner unit has many parts. Some are easy to repair and maintain, while others are not. I’ve included the guide below for you to look over. Usually, these are what technicians check during scheduled visits.
1. Air Filter:
An air filter protects the internal unit from contaminants in the air, like dust, fibers, and pollens. It serves as a guard to keep the air conditioner in shape. And it also protects inhabitants, especially those who have allergies.
Air Filter Repair:
Air filters are disposable. Once it is too dirty, it is time to replace it. Detaching it is not difficult, and putting on a new one is easy. As for the schedule, replacement should be at least every three months or ninety days.
2. Evaporator and Condenser Coils
The evaporator and condenser coil work together to keep the room cool. The evaporator coil removes the heat from the air indoors and cools it. Then the heat absorbed is taken out by the condenser coil and blown outdoors.
Evaporator and Condenser Coils Repair:
Please take a look at the evaporator and condenser coils for damages. Cracks or holes can cause the refrigerant to leak out and damage the air conditioning unit.
If the two are in condition, cleaning them requires a garden hose.
Condenser coils are easy to spray with water. If it is too dirty, an aircon coil cleaning solution is needed. The evaporator coil is in a narrow space. Spray cleaning is tricky, so do it slowly and at close range. Please watch out for the wires and other components near it.
3. Drain Pan and Drain Line:
The drain pans prevent water from leaking caused by condensed air. These drippings flow in the drain line and go to the collection tray. It serves as excess water disposal for the system.
Drain Pan and Drain Line Repair:
Cleaning a drain pan does not require fancy tools. A rag will suffice to wipe it. But if it is slimy and full of grime, you can just use a vacuum cleaner. It should be capable of both wet and dry elements.
A drain line would require some mild brushing. You can use a flexible brush when scrubbing the drain line. It is outside of your house where the unit drains out water. Then check the air handler and detach the vent cap from the top of the vent tee.
Continue scrubbing out the dirt, grime, and algae to prevent clogs. If there are thick algae, dispose of it by pouring a mixture of water and bleach. The ratio should be one cup of water and bleach to prevent algae regrowth.
4. Condenser and Blower Fan:
Condenser fans remove heat from the cooling system through a heat pump. Then the cool air is blown out by a blower motor. This process delivers cold air inside the room and prevents the condenser from freezing.
Condenser and Blower Fan Repair:
Condenser fans have exposure to the environment. It requires lubrication to prevent it from making a noise. When the fan is off, loosen and take out the screws of the top unit. Pull out the panel to view the fan motor. Use a syringe to inject the oil. An applicator is also another option.
The blower fan uses centrifugal force and can displace air. Inspect this part by opening the access panel covering the handler unit. Check the fan for debris, see if it is rotating freely, and there should be no vibration. Take special notice of the fan belt and pulleys. As a preventive measure, schedule belts replacements yearly.
The thermostat regulates the air conditioner’s function by measuring the temperature indoors. It instructs the unit when to switch on and off. Setting it higher can reduce the electric bill.
Check the fan speeds to see if it is appropriately running. Then, using a portable temperature sensor, you can compare it to the thermostat reading. If it’s a match, there is no problem. If it doesn’t, please call a professional to manage this item.
Observe also modulating valves or dampers. These parts must open and close with ease. The thermostat is doing well if it does. If any abnormality occurs, a skilled technician should fix it.
6. Air Conditioner Ductwork
The ductwork is a group of ducts that features metal, polymer, or synthetic tubes. It aids the air circulation from the ventilation, heating, and aircon unit inside your home. It maintains the air quality indoors and provides comfort.
Air Conditioner Ductwork Repair:
Inspect the ducts for dust, mold, and air leaks. If there is dust, wipe it off with a rug. Molds are removable by scrubbing with a utility brush. A sponge with a light detergent also helps in eliminating molds.
Air leaks can cause the formation of dust. Check all the seams and connections of the ductwork. If there are leaks, seek the help of a professional to seal the area affected.
