When your air conditioning system isn’t functioning as it used to–or has stopped functioning–you need an air conditioner service company you can trust. Air Conditioner Calgary features a team of experienced and certified HVAC professionals who can quickly evaluate your AC unit to determine its problem. Then, we can deliver the ideal fix. There are many air conditioning problems that seem to pop up more frequently than others. In this blog, we’ll discuss the most common AC problems and why they occur.


Air Conditioning System Is Blowing Hot Air


When your AC is on and you walk past a vent, you expect to feel cool air. When the air coming from the vent is warm or hot, you definitely need air conditioner repair. Sometimes the solution is an incredibly easy fix: a change of air filter. When the air filter becomes caked with dirt, it can lead to this problem and, if left unchecked, can cause other problems for your unit as well. 

The problem can also occur because your unit’s refrigerant is low, and there could even be a refrigerant leak. In addition, the unit might have dirty condenser coils or leaking air ducts. Air Conditioner Calgary can take the guesswork out of the problem and provide the AC repair service you need to get your system working properly again.


Frozen Evaporator Coils


Frozen evaporator coils are another common problem that affect AC units. Frequently, this problem is caused by a dirty air filter. However, a malfunctioning fan or blocked ducts can also affect the air circulation in the unit, which can cause the coils to ice up. Sometimes the unit’s condensate line becomes blocked, and that too can lead to frozen evaporator coils. If you notice that the coils on your outdoor unit have ice up, turn off your system and call our Calgary AC repair service right away.


AC Unit Won’t Turn On


If your air conditioning system won’t turn on, a breaker may have been tripped. Customers can flip the breaker switch back on in these cases, but if it trips again, there’s likely a loose wire. The problem may also be due to a malfunctioning thermostat. Our AC repair technicians can pinpoint why your unit won’t turn on. Our techs will bring diagnostic equipment to determine if the problem is wiring or something else. 


Unit Turns on and off Repeatedly


If your AC unit is turning on and off repeatedly, you should turn it off anc contact our air conditioner service. The repeated action can cause damage to your AC unit’s compressor. The problem, referred to as short cycling, may occur because the thermostat is malfunctioning or the air filter is clogged. If your AC unit’s evaporator coils have iced up, short cycling can also occur. This can be a frustrating issue, but Air Conditioning Calgary can inspect your unit to find out exactly why it’s occurring. 


Strange Noises Are Coming from Your Unit


Strange or unusual noises coming from your AC system should be a cause for concern. Frequently, this issue points to a wearing belt, but not always. There could be a problem with the unit’s motor bearings, which is serious. Do you hear a hissing sound? In this case, the problem could be that the refrigerant is leaking. Do you hear a buzzing noise? This is often indicative of an electrical issue. A screeching noise usually points to the compressor fan. 

Our air conditioning Calgary tech team can quickly troubleshoot this type of problem. After they find out where and why the noise is occurring, they can make the necessary repairs. We bring everything needed to address our customers’ AC issues so we can get their systems up and running as quickly as possible. 


AC Unit Is Leaking Water


If you walk by your outdoor AC unit and notice that it’s leaking, there could be several issues at play. But first–don’t panic. Sometimes this is a normal occurrence, especially on an extremely hot or humid day. However, it could also indicate low coolant levels or a blocked drain pipe. It’s not uncommon for water leaks to occur when the condensate pan is cracked or broken. It’s a good idea to contact Air Conditioning Calgary when your unit is experiencing unusual issues. With a careful inspection, we can find out why the leak is occurring and repair it before it can lead to other system problems.


Refrigerant Leak


A refrigerant leak is definitely a problem for an HVAC repair specialist. If your AC unit isn’t cooling your home as it used to, you should have the issue inspected as it could indicate a refrigerant leak. A refrigerant leak can be damaging to the environment. Your system will not cool as well as it used to and may experience other problems. Our technicians will determine if a leak is present. Then, we’ll fix it and add more refrigerant as needed. 


Ward Off Problems with an Annual Air Conditioner Tune-Up


Did you know that many common AC problems can be identified during an annual AC inspection and tune-up? Unfortunately, many types of AC problems can cause damage to other elements of your AC unit–which leads to even larger and more expensive problems. Our technicians can carefully inspect your unit before the summer season to ensure it’s working properly. We can identify signs of wearing parts such as wearing belts before that can break and damage your unit. 

We’ll check your unit’s refrigerant level, test your thermostat, and get your system ready for the warm season ahead with a complete system tune-up. While an inspection and tune-up can’t ward off all problems, it can ward off many, and support the longevity of your HVAC system.
