Air Conditioner Not Cooling Well

Is Your AC not cooling enough

Is Your AC not cooling enough?

Summers are hot, they are humid and they are extremely uncomfortable. But all these discomforts can be alleviated by the installation of an air conditioner in the room. By decreasing the room temperature and cooling it to a point where it makes the room extremely comfortable, the air conditioner is a blessing which makes the hot summer months bearable.

But there might be times when the air-conditioner is not able to provide the promised cooling effect. This makes for an extremely hot, irritating and frustrating summer with one literally feeling “hot under the collar”. There are many reasons for the air conditioner not working properly and some of the main problems commonly faced are:

  • Air filter clogging: The fundamental work of the air filter is to ensure clean and hygienic air percolates into the room. Thus excessive use of the air conditioner in summer tends to make the air filter quite dirty as it traps dirt and dust particles present in the cool air entering the room. This results in the clogging of the pores of the net of the same thereby reducing the amount of cold air entering the room thereby making the room considerably hot and uncomfortable. When such a situation occurs, the air filter either needs to be cleaned or replaced.
  • Coils are dirty: The work of the condenser coil is to ensure that the heated gas coming from the evaporation coil cools down considerably and gets converted into liquid by releasing its latent heat. But if these condenser coils become dirty and get covered with leaves, plants, debris etc., it will not be able to release heat to the atmosphere outside thereby making the air-conditioner much less effective than it should be. Cleaning the condenser coils generally solves this problem.
  • Coolant or refrigerant charge is less: The circulation of the coolant through the evaporation coils helps cool the flowing air surrounding it thereby sending this cool air into the room. But the presence of insufficient coolant hampers this process and can even cause damage to the air conditioner. Filling it up with sufficient refrigerant generally solves this problem provided a leakage is not the reason for this insufficiency. In case of a refrigerant leak, simply replacing the amount leaked will not solve the problem and will only result in financial loss. In this instance unless the leak is detected and sealed, the air conditioner should not be used. Some warning signs which can help identify a plausible refrigerant leak are:
    • Icy build-up on the copper coils entering the compressor,
    • Room takes a really long time to cool down to the temperature set and
    • Strange hissing sounds start emanating from an air conditioner when in operation.
  • Compressor is faulty: Known as the heart of the air conditioner, the compressor is responsible for the cool comfort one experiences in a room. The work of this compressor includes a refrigerant compressing motor which then helps to circulate this coolant through both the evaporator coils as well as the condenser coils. Thus any fault in the motor or any other part of the compressor stops the air conditioner from functioning and needs to be corrected by placing a call to a HVAC service provider like https://www.airtimeheatingandairpro.com/ .
  • Defective thermostat: It is this unit which ensures the auto-sensitivity of the air conditioner. Depending on the temperature set, the thermostat tends to cut off the compressor when the temperature is reached and start it again when the temperature goes down. Thus any fault in the thermostat will automatically result in the malfunctioning of the compressor thereby rendering the AC unit ineffective in cooling the room.
  • Atmospheric temperature is high: Every air conditioner comes programmed to operate effectively at an optimum surrounding temperature. Thus any hike in the surrounding temperature causes the air conditioner to lose its efficiency and an extremely high atmospheric temperature can even completely stop the AC from functioning.
  • Undersized AC: The capacity of the air conditioner installed should be such that it is proportionate with the dimensions of the room. However, due to either budgetary constraints or sheer lack of knowledge, many a times people tend to buy undersized air conditioners. These units when installed are not able to cool the whole room effectively and may also trip and stop working completely when under pressure during the extremely hot summer months.
  • Faulty remote: The remote helps to control the temperature settings and other functions of the air conditioner like air outflow, spread of the air flowing out etc. This creates a problem since the air conditioner can only work when the remote sends it proper signals. Thus it needs to be replaced with a new remote for the air conditioner to start working perfectly fine again. 

Other common reasons include a fault in some of the other lesser important parts like the compressor capacitor, control board, choked capillary etc. In order to ensure that these problems do not recur, it is important to ensure that maintenance of the air conditioner is regularly scheduled and carried out with honesty and sincerity.
