Air Conditioner

An air conditioner cools down the temperature inside your home or office by removing the existing heat and moisture. Nothing is worse than having a faulty air conditioner on a hot day. When you discover your AC is blowing warmer than cool air, it can be a sign that there is a problem. There is quite a common problem and luckily there are some things you can do to fix it on your own. Here are some of the factors why your air conditioner may not be cooling your house.

Dirty Air Filter

A clogged filter limits your airflow regardless of the AC you are using. Dirty filters affect the efficiency of your ac, and your system seizes to cool your home or office. If you do not know how to clean your filters in the recent past, consider calling an AC expert like Lynn’s air conditioner repair. Remember to change the central AC filter for at least one month, especially if you run the system a lot.

Refrigerant Leak

Leaking air refrigerant spells a problem for your cool and comfortable home. If your AC is not cooling your space, consider checking the refrigerant pressure. AC experts recommend seeking help from a professional right away since HVAC refrigerants can cause a health problem. Additionally, your refrigerant may not be leaking or low, but you see moisture on your unit. This could be a result of condensation. However, your pipes could also be blocked or leaking, or your condensation pump may not work. Ensure you check the condensation draining line and clean any algae on your system with bleach.

Thermostat Setting

If your HVAC unit is blowing hot air instead of cool air, you may have set the thermostat to heat instead of cool. Thermostat reading is another issue you may experience. If your AC thermostat temperature seems off, you may have exposed the thermostat to direct sunlight. This exposure prevents your AC from blowing cold air. As such, avoid exposing the thermostat to direct sunlight.

Broken Fan

Your fan helps release heat into the surrounding air. A broken fan leads to cooling issues. If the fan of your outdoor unit does not turn on, your AC will not cool your home. Consider pressing the reset or overload button to rest the unit when this happens. You can also try spinning the fan blades clockwise while the AC unit is turned off. If the fan blades do not move freely, you might have a problem with your capacitor, and it might need a replacement.

Clogged AC Unit

Your outdoor compressor must have a decent airflow to work correctly. However, you should ensure that you have at least two feet of space between your compressor and any structure. You should also ensure that your outdoor ac unit is at least five feet above your trees. When your AC starts turning on and off repeatedly, you have a potential clogging problem. Check whether your condenser is blocked or your evaporator is dirty. Always check for obstructions and give your unit a good cleaning to clear any debris.

These are some of the reasons your AC is frozen. Fortunately, you can prevent or correct most of these problems.
