Aside from the discomfort, having an inefficient HVAC can account for as much as half of your home cooling cost according to the Department of Energy. Learn more about how your AC works and follow these tips for the best-working AC unit.
How Your AC Works
Whether you have a split system or packaged system, the cooling process works the same way. In essence, the unit is transferring heat from inside the home to the outside using a system of coils (evaporator and condenser), fans, a pump (compressor), filter, and thermostat.
The evaporator coil removes heat and humidity from the air using refrigerant and cool air is then collected and blown into the home. The condenser coil collects heat, and a fan then blows the hot air to the outside of your home. A compressor pumps refrigerant between the evaporator and condenser.
Keep Air Filters Clean
To keep your air cool and to lower energy consumption by 5-15 percent, change your air filter regularly. Depending on your needs, the frequency can range from monthly to seasonally. It may be helpful to set reminders on your phone to ensure your filters are maintained.
So how often do you make the switch? Factors that determine how often to change your filter include the type of filter, the air quality of the home, whether you have pets, pollution in your area and how many people live in your home. It’s best to check your filter monthly. If it seems dirty to you, then it’s time to change them.
Maintenance is Key
Check the evaporator coil annually and clean it as needed. If you have a split system, keep the fan, compressor and condenser clear of debris and leaves. Occasionally pass a stiff wire through the unit’s drain channels to prevent clogs. On final note – coil fins cannot be bent. If you find this is the case, you can straighten these out with a fin comb.
