Check Your Thermostat

If you’re not feeling the cool breeze from your AC, it’s important to check your thermostat settings. If you set your thermostat too high, the AC might not even turn on. For instance, if your AC is set to 28°C and the current temperature in your home is 24°C. Also, if you’ve set your AC to the ‘auto’ setting instead of ‘on,’ it might not be cooling your home effectively. 

There are a few things you can do to investigate what’s going on. Ensure that the breakers are functioning properly, and check to see if the air conditioner shut-off switch is flipped.

Change Your Filter

One of the most important maintenance tasks for any homeowner is changing the air filter in their heating and air conditioning unit. A dirty air filter can lead to a number of problems, including reduced airflow, increased energy consumption, and even system failure. If you haven’t been regularly changing your air filter, your AC probably has a dirty air filter that is now clogged. 

A clogged filter in your AC unit restricts the airflow in your home and could potentially damage other parts of the AC like the evaporator coil. It’s important to check your filter every 30 days, and remember to clean it regularly.

Clean Condenser

Your condenser unit is an essential part of your air conditioning system, and it’s important to keep it clean and well-maintained. When dirt and debris get into the condenser, it has to work harder to pull in the air and cool it. 

Fortunately, cleaning up your outdoor condenser unit is something you can do on your own. Just be sure to turn off the power to the unit before you start cleaning. Then, use soap and water to remove the buildup of dirt. Once you’re finished, be sure to turn the power back on and check that the unit is running smoothly.

Get the Right AC Size

Air conditioners come in a range of sizes, and it’s important to choose the right size for your home. If your air conditioner is too small, it will have to work overtime to cool your home, which will wear it out more quickly.

If your air conditioner is too large, it will cool your home too quickly and then shut off, leading to wasted energy and uneven cooling.

Check for Leak in Ductwork

A leak in the ductwork of your home could be costing you money and ac not blowing cold air. When ductwork leaks, cold air is filtered out into the walls instead of reaching the vents.

This not only means that your home is not being properly cooled, but it also means that you are paying for cooling that is not benefiting you. To ensure that your ductwork is in good condition, have it inspected regularly and repaired as soon as any leaks are detected.

Check for Frost

An air conditioner freezing up is not normal behavior and can indicate a serious problem. If your AC unit freezes up, it may be due to a clogged filter causing a dirty coil. This means the frozen evaporator coil can’t absorb any heat, and the ice will continue to build up.

Another possibility is that the condensate line is blocked, which prevents the excess moisture from draining properly. This can cause the coils to freeze and the ice to build up. Finally, low refrigerant levels can also cause the coils to freeze. If you notice your air conditioner freezing up, be sure to check these potential causes so you can fix the problem as soon as possible.
