On most models, the air filter is easily accessible by removing the front panel. Remove the filter and clean it gently with a combination of warm water and dish soap or white vinegar. Let the filter air dry completely before reinstalling it. These should be cleaned once per month during the cooling season. If you have pets or allergies, consider cleaning it more frequently. If the filter has tears, holes or other damage, it should be replaced. If your unit has a foam filter, you can purchase replacement electrostatic filter material and cut it to accommodate the exact size of your model.
If you've left your air conditioner uncovered in your window or wall over the winter, you'll need to check for wasp and bees' nests inside of the unit. Avoid problems with this in the future by storing your window air conditioner in a protected area such as a basement or utility room during the off season. If you must leave your AC in the window, use an air conditioner cover.
Over time, dust and dirt will build up on the inside of the air conditioner's condenser coils. This build up will require your AC to work harder to remove heat – increasing energy consumption and your monthly electric bill.
At the start of every cooling season, clean the condenser coils. You'll need to remove the air conditioner cabinet completely in order to access the coils. They can be cleaned by blowing compressed air at them or by using a soft bristle brush and a spray bottle of household cleaner to wipe the dirt off.
Take great care in removing the dirt. If you accidentally bend or dent the aluminum coil fins, use a handy fin comb to straighten out the fins.
It is also important to remove dirt or lint build up at the bottom of the air conditioner so the condensate water will be picked up by the condensing fan blade slinger properly.
If the temperature outside the room where the air conditioner is placed becomes cool (approximately 60 degrees Fahrenheit or 15 degrees Celsius or lower), check the coils on the front of the air conditioner for icing. Ice buildup on coils means the temperature is too low for proper operation of the unit. You should use it only when the outdoor temperature rises above 60 degrees Fahrenheit or 15 degrees Celsius.
After going through a long summer pumping cool air through your home, your central air conditioning unit is finally enjoying a much-needed rest during winter. There are some essential steps that you should take to protect your AC unit during winter so that it will be ready to serve you better when the temperatures start to rise again.
Typically, the air conditioning system has been built to survive in tough weather, and some homeowners say that their AC units still work fine even when they fail to implement any protective measures during winter. However, the outdoor unit may be damaged by debris, repeated freeze-and-thaw cycles, and moisture buildup if you fail to perform any protective action during winter.
Most homeowners have been wondering whether it’s good to cover the air conditioning unit during winter. In fact, this has been a heated debate in the heating and cooling industry for long. Nonetheless, there are several advantages to covering your unit.
It may not be necessary to cover your AC unit if you live in areas that don’t experience hailstorms, but if you live in the north, it might be worthwhile if you consider covering it in winter. For instance, it’s not strange to encounter hail in the Midwest.
Although it’s difficult to know when a massive storm is coming, covering your AC units acts as a proactive measure that safeguards it against potential destruction. Dripping water from gutters and trees can also get into the system. The water turns into ice when temperatures drop which can damage the fins.
Covering your AC units helps in keeping your air conditioner coils a little cleaner since external dirt is kept at bay. This will help it to run a little more efficiently when it’s time to use it again in the summer. An air conditioner cover also makes the AC unit look better in the long run.
One of the most sensitive parts of your AC unit is the fins of your outdoor air conditioner’s condenser coils. Flying leaves and debris can cause severe problems to your unit. The coils won’t be able to release cold air to cool your home when the temperatures begin to rise in summer.
Apart from covering your unit, you should also consider cleaning the coils before the hot season begins. Sometimes, falling ice can also hit the unit with a lot of force causing severe damage to the delicate coil fins.
If you know that you’re living in an area prone to snowstorms, then covering your air conditioner unit can help a big deal. If snow accumulates inside your unit, then melting and refreezing it will automatically damage the coils. Make sure that you cover your AC unit just before a blizzard and uncover it after. You should also spare some time and clear the snow around the outside unit.
