A home cooling system is a big investment, and it’s important to take care of it. While there are some Air Conditioner repair & maintenance tasks that you can perform yourself, the best way to keep your AC running smoothly is to schedule regular maintenance twice a year. This will ensure that your system is clean, working correctly and ready for the summer heat.
Change air filters
This simple task can significantly improve your AC’s efficiency and extend its lifespan. In addition to reducing energy costs, it can prevent dust and allergens from entering your home through the vents.
Clean coils
Air conditioning units produce a lot of condensation, and the drain line that carries it away is sometimes clogged or full of mold and mildew. It’s important to empty and clean this line regularly to avoid water leaks, which can cause severe damage to the system.
Inspect ductwork
Leaky or dirty ducts can significantly reduce your air conditioner’s efficiency and increase the cost of heating and cooling. During maintenance, the technician will inspect ductwork for signs of damage and seal any gaps. They will also replace the air filter, check the evaporator coils and test the thermostat and electrical components for proper function and operation.
Verify a functioning float switch and drain pan
Over time, the float switch in your condensate drain line may become stuck, which could cause your system to shut off unnecessarily. It’s important to have this checked regularly by a professional to make sure it’s functioning properly and preventing your system from overflowing.
Examine the unit for any electrical wiring or loose connections
The electrical connections on your AC system aren’t something you can easily inspect, so it’s important to have them inspected by a professional at least twice a year. A trained technician will be able to identify potential issues and repair them before they turn into serious problems.
Inspect the fan blades and motor assembly
The blades on your air conditioning system can become damaged by insects, debris or overheating. It’s important to have them cleaned regularly, and you should also replace any worn or broken blades.
Look for any signs of rust or corrosion
Eventually, the metal components on your air conditioning system will rust and corrode, which can lead to short circuits and fire hazards. During your maintenance visit, a technician will check all of the connections and fasteners on the unit for damage and corrosion and tighten any loose ones.
Before you begin any maintenance tasks, it’s essential to turn off the power to your air conditioner at the exterior condenser/compressor. There’s usually an exterior shut-off box near the unit, or you can find the breaker box inside your home and shut it off at the breaker panel. It’s also important to wear rubber gloves when you work around your AC unit, as the moving parts can be dangerous. You should also disconnect the wires from the unit’s terminal block to make it safer and easier to work on.
