As with all appliances, you'll get more out of your air conditioner if you maintain it properly. In addition to helping you save energy and keeping your home more comfortable, maintenance can add years to your AC's life. Here are three maintenance tips that extend the life of your air conditioner.
1. Change the Furnace Filter
Furnace filters serve an important function by protecting your HVAC system from dust. With a clogged or damaged furnace filter, dust and other contaminants circulating through your system may collect inside your air conditioner. This can lead to overheating as the dust traps exhaust heat around internal components.
Changing the furnace filter is the most basic HVAC maintenance task that every homeowner should be comfortable with. The filter is located in an easily accessible area near the furnace and can be replaced by simply opening the filter grate. Many technicians recommend changing the filter monthly to protect your furnace and air conditioner from damaging dust buildup.
2. Clean the Evaporator Coils
In a central HVAC system, the evaporator coils are located above the furnace blower inside the home. Refrigerant is cooled before it reaches your evaporator coils and expands within the coils to absorb heat. However, dust and dirt on the coils can cause your AC to underperform by blocking heat transfer. This often results in long cycle times, frozen coils, and increased strain on your AC.
Even with regular filter maintenance, your central AC evaporator coils can become clogged with dust and grime through normal use. DIY-oriented homeowners can clean the evaporator coils themselves with a wire brush and commercial coil cleaner. Alternatively, you can leave the task to your HVAC technician as a part of your regular professional HVAC maintenance plan.
3. Keep the Condenser Clear
Modern central air conditioners are connected to a condenser installed outdoors. This unit is responsible for circulating refrigerant and expelling heat from your home outside. Obstructions around the condenser can inhibit the heat removal process, which may lead to overheating in the condenser.
In spring and summer, greenery is the most common culprit behind a blocked AC condenser. Trim grass and shrubbery around your condenser regularly to ensure proper airflow. You should also take caution when placing lawn decorations or furniture near your condenser.
Central AC maintenance requires minimal effort and rewards you with years of efficient operation from your HVAC system. Contact an HVAC technician for professional maintenance and additional tips to prolong your air conditioner's life. For more information, contact a company like Wyoming Air.
