The majority of households in Canada use air conditioning. Air conditioning utilization increases during summer. Some of the users, however, experience difficulties when starting their air conditioners. When troubleshooting for problems common with those appliances, some of the most prevalent issues include failure to turn on, thermostat glitches, condenser problems, frozen evaporator coil, and leaking or dirty ducts. While regular air conditioner maintenance will sort out many of these issues, an occasional emergency can arise with your AC system. Smile HVAC is a professional company dealing with the installation and repair of air conditioners. This article will inform you about the most common air conditioners’ issues and how to fix those problems.
Failure of Electric Control
One common issue prevalent in air conditioners is a failure to turn them on. Unavailability of power could be something as simple as a blown fuse or a tripped trip switch. One will therefore have to relax the trip switch or replace the blown fuse. Trip switches shut off after a power surge; this is an essential aspect since it averts homes from catching fires. Moreover, the wire connection should be checked. Electrical and wiring problems can result in damage and fire.
Thermostat glitches are another common issue faced by homeowners. If the thermostat is faulty or calibrated wrongly, the air conditioner may not turn on. If the thermostat is set to the lowest temperature setting and the system fails to start, then you should consult a technician to correct the calibration. The older dial-type thermostats often have calibration problems, but sometimes the recent programmable thermostats are hard to program. One should consult the thermostat manual to ensure that he or she programs the thermostat properly.
Dirty Condenser Coils
Also, condenser problems, which heat things, are common in air conditioners. The condenser has a crucial role to perform. The primary function of a condenser is discharging the removed heat from the air. This is accomplished by releasing the heat outside the building. The outdoor unit consists of the condenser coil, which is exposed to dirt, various pollutants, and soot that makes it grimy. Dirty coils interfere with the heat transfer, therefore, overworking the unit. It can malfunction the entire AC system.
Frozen Evaporator Coil
A frozen evaporator coil could be another common problem with air conditioners. Temperatures slightly warmer than desired could be caused by the evaporator coil. Within the coil, there is a coolant that absorbs heat. The evaporator coil accumulates some ice when there is a reduced flow of air. After this happens, it leads to slightly hotter air or absence of air supply from the conditioner. To solve this issue, start by assessing the level of damage. Allow the coil to defrost. This is achieved by letting the unit rest for some time. If the problem is not solved, then call a professional to fix your air conditioner.
Dirty Air Filter
The limited airflow could be caused by air filters containing dirt, low refrigerant, and blocked backflow of air within the ductwork. Small particles, grime, muck, and the unpleasantly sticky substances can also accumulate on several parts of the air conditioner; filter area, air condensation area, and evaporator coils area. Air conditioners are made up of components that are at risk of being dust and dirt accumulation points. Waste accumulation leads to reduced competence of the various parts of the conditioner leading to less productivity. The waste build-up also damages the air conditioner. It is advisable to follow the manufacturer’s directions on when to replace or remove debris from the filter. If the airflow seems to be obstructed, one should examine the filter and remove all dirt from it.
Warmer air could be a result of the improper flow of air through the air conditioner’s ducts. Central air conditioning systems are sealed, and their vents span along walls and ceilings. These ducts get damaged and torn along their course more than often. Ducts deliver ventilation air as part of the supply air. Tears facilitate the escape of cool air from the ductwork. Leaks in the ducts cause a general increase in the house temperatures hence demanding more work from the air conditioning system. This leads to more use of power, therefore a higher electricity bill. One of the ways of resolving this scenario is by using duct sealing tapes. However, calling a professional to seal leaky ductwork produces the best results.
The compressor is a significant part of the framework since it regulates pressure within the air conditioner and ensures proper refrigerant flow. Compressors work hard and will eventually need to be replaced. Compressor functionality depends on the amount of dirt on the coils, refrigerant flow levels, and capacitors’ types and efficiency. Seek help from professionals if the air conditioner is blowing out slightly warmer air than before. Many air conditioner problems related to the compressor are misdiagnosed. It is advisable to seek the services of a professional in repairing air conditioners.
Let’s take a look at the tell-tale signs of an imminent air conditioning repair:
Sign #1: If there is little to no airflow
Sign #2: AC is blowing warm air
Sign #3: Bad smell coming from the AC
Sign #4: Unusual sounds coming from the AC
Sign #5: Crashed/malfunctioned thermostat
Sign #6: Moistness in the home
Sign #7: Moisture leaks in or around AC
The Air-condition system needs to be serviced regularly to avoid potential malfunctioning in the future. Even if it is working perfectly now, don’t miss out on maintenance, especially before summertime. Having a failure or any issue with your AC during the hot Canadian days will definitely be a pain. This article presented common issues with air conditioners and how to fix them. If you are unable to resolve any issue, call the Smile HVAC team to handle it ASAP.
