Common AC Problems To Look Out For
In preparation for the Saskatchewan summer months, you will want your AC to be working effectively. Luckily, you do not need to be an expert to be able to tell when there is something wrong. Here are some common AC problems to be aware of so you know what to look out for.
Hot Air Blowing
On a warm summer day, the last thing you want is hot air blowing through the home. If you notice your AC is blowing hot air, first check the air filter and also check the coils on the outside unit to ensure they are not dirty. Also, ensure there is no loose ductwork or blocked air vents. If everything checks out, it is likely that there is a problem with the compressor. Insufficient lubricant, blocked suction lines, or electrical problems can cause compressors to fail. These issues will need to be dealt with by a professional.
AC Compressor Break Down
The AC compressor is the part of the system that moves refrigerant through to cool the air. Because compressors are a component that gets constant use, they tend to wear out quickly. However, they may also break down for a few reasons including electrical issues, lack of lubricant, too much or too little refrigerant, or dirty condenser coils.
The good news is, that there are a few warning signs to indicate AC compressor failure. Signs the AC compressor is about to break down include warm air blowing, the circuit breaker tripping, and shaking or unusual noises when the air conditioner kicks in.
Frozen Evaporator Coils 
Even on the hottest Saskatchewan day, evaporator coils have the potential to freeze. Since evaporator coils are an essential component of your AC, your system becomes useless until they are defrosted.
Evaporator coils absorb heat from inside the home. As heat is absorbed, it causes condensation build up on the coils. Coils can freeze due to a number of issues such as dirty air filters, dirt build up, and low refrigerant levels. Frozen evaporator coils significantly slow down the AC system’s cooling ability. If the coils on your AC system have frozen, be sure to immediately turn off the system and allow them to defrost, and schedule a professional to come and fix the problem.
Evaporator coils are not the only AC component that can freeze. Condensor coils on the outside unit can also freeze. This can be prevented by keeping debris away from the unit and regularly cleaning the coils.
Strange Noises
If your AC unit has been making strange noises, it is likely you have been blocking them out. There are a a few noises that indicate a problem with your AC.
Clicking noises – Clicking noises usually indicate a problem with the thermostat, which is an electrical issue. Keep in mind AC systems do make clicking noises when they start up and shut down, but ongoing clicking is a sign of a problem.
Squealing noises – Squealing noises are caused by the belt. Often belts will go out of alignment or wear out. A malfunctioning fan motor or blower wheel can also cause squealing noises.
Grinding noises – Grinding noises indicate there is an issue with the motor. Popping or pinging indicates metal is loose, and rattling indicates cover panels are loose and need to be tightened.
Banging noises – Banging noises indicate that a compressor replacement is in order. A banging noise is likely coming from inside the compressor from a loose or broken piece.
Screaming noises – Screaming or whistling noises indicate a refrigerant leak. If you hear these, turn the AC off and call a professional. Refrigerant leaks not only damage the unit, but are a health danger. Screaming noises can also indicate that the internal pressure inside the compressor is too high. This is also a safety issue, and should never be ignored.
Being aware of common AC problems will ensure you know when it is time to call in a professional to service your system. Catching problems early allows them to be taken care of so you enjoy a cool home all summer long.
