Other General A/C Maintenance Tips
Maintaining your unit is one of the best things that you can do to ensure the longevity of your air conditioner. There are a lot of easy tasks that you can carry out as a homeowner that won’t take too much time or effort. With a little patience and your owner’s manual, you can keep your air conditioner running efficiently for years. Make sure to turn off power to your unit before opening it.
1. Clean around your unit
Take care to ensure that the two feet around your unit are free of debris like leaves and plant growth. Trim back excess flora and remove anything near or on your air conditioner so that air can flow freely.
2. Clean and straighten the fins
The fins can be cleaned by using a garden hose on a gentle spray setting and spraying from the inside out to remove debris and dust that is trapped. Avoid using too much pressure because you may damage the delicate fins. To straighten the fins, you can try a fin comb from a hardware store or use a butter knife carefully to put the fins back in place.
3. Level your unit
If the pad that your unit is resting on has tipped due to soil flattening underneath, the uneven tilt can cause the compressor to fail or become damaged. Fix the pad your unit is on until it rests evenly on the ground.
What’s Wrong With Your Armstrong Air Conditioner?
Remember to turn your A/C completely off before opening it up to look around or attempt any fix.
|Is your air conditioner...||The problem might be your...||What's wrong?||How you can fix it|
|Thermostat||The batteries in your thermostat may be dead, or the thermostat may not be on the correct setting.||Put new batteries in your thermostat and ensure that it is on the cool setting.|
|Circuit breaker||The breaker switch may have flipped.||Move the breaker switch back to the “on” position.|
|Not blowing cold air?||Air filter||If the filter is clogged with debris or dust, it won’t be able to do its job.||Replace or clean your air filter so that air can flow freely.|
|Outside unit||The air conditioner may not be able to have air flowing freely if there are dirt and debris around the unit.||Make a two-foot space around your unit that is clear and free of leaves, greenery and any other blockage so that it can vent air properly.|
|Refrigerant||If the refrigerant is leaking, your unit will not be efficient at cooling since there is less cooling fluid to run through your unit.||Get a technician who can solve this problem.|
|Insulation||Insulation is important to keep air from leaking out. Cracks, old windows and doors are all spots where cold air can escape.||Windows are the main places where cool air escapes. Consider upgrading to insulated windows or use blackout curtains.|
|Dripping water?||Condensate line||The pipe that exits your air conditioner could be clogged.||Blow compressed air through the pipe to dislodge the clog.|
|Drain line||Water can overflow in the drain pan if the drain pipe is blocked.||Check the drain line for any clogs and remove them.|
|Making odd sounds?||Blower motor or belt||Squealing sounds can come from the belt or the blower motor.||Use lubricant on the parts to help them run better without squeaking.|
|Fan blades||If the sound is repetitive like a card stuck in a bicycle spoke, there is a chance something is caught between the blades.||Switch your unit off and check the fan blades to see if anything is trapped and remove it carefully.|
When to Get a Technician for Armstrong Air Conditioner Repairs
Though there is a lot of maintenance that you can do on your air conditioner unit by yourself, there are a few things that are better addressed by a technician. Regular check-ups on your unit can help avoid significant repairs or a possible replacement in the future. If you’re experiencing any of the issues listed below, it’s best to get a professional in to fix your air conditioner.
Frozen coils typically happen when something has gone wrong in your unit. Determining the issue can be a challenge, as the source of the problem can be with the ducts, drain or internal parts that are dangerous or tricky to see and change.
Clicking sounds when your A/C turns off or on can be symptomatic of a relay issue or suggest that an internal part has come loose.
A damaged compressor can cause a lot of problems, the main one being that air won’t be flowing properly. This will take a technician to diagnose and repair, as it’s a very involved job.
Leaking refrigerant is a serious problem that can impact how well your air conditioner can cool your home. You’ll need a certified technician who can address this issue to bring your unit back to efficient standards.
