However, have you ever given thought on how to keep your air conditioning unit running in top condition at all times? We just hate it when the AC breaks down and the heat is quickly growing unbearable. So how could you tell if your AC is about to fail and what are the things you could do to prevent it from failing?

8 common HVAC issues that prevent cooling
Bad thermostat settings – it may seem too simple to be a problem, but incorrect thermostat settings could be the culprit. If you want to save money and lower your energy consumption, you should set higher temperatures during the day. However, you should not set it “too high.” During summer, you should not set the thermostat over five to eight degrees above your preferred home setting when you are away. This will make the temperature range conducive to your comfort and also decrease the amount of stress that is placed on your HVAC system North Myrtle Beach. Don’t forget to check your fan settings. It should be set to auto so that your unit will not blow warm air all throughout the day.
Filthy air filter – a filthy air filter can lead to different problems like warm air coming out from vents, frozen evaporator coil, and restricted airflow leading to cooling inefficiency. Whatever problems you are experiencing, a filthy air filter is going to make your HVAC unit work harder and prevent it from cooling properly. In case your evaporator coil, which is part of the indoor unit, freezes, it will eventually begin to melt and when the unit is located on the upper floor, there could be leaks through the ceiling below. How often you should change your filter will depend on several factors like if you have pets, have allergies, and the quality of the air filters that you are using.
Closed or blocked air vents – just like the thermostat settings, you should also check your air vents before you call an HVAC contractor. Pay close attention to areas or rooms that are more humid or hotter than the other parts of the house. Check every vent in your vent and be sure that all of the air vents are unblocked.
Refrigerant issues – if your unit is low or leaking refrigerant, you should immediately call the pros. Problems with the refrigerant are usually caught by HVAC contractors especially during routine maintenance inspections. You will know that the refrigerant is leaking if you hear a hissing or bubbling noise, the air conditioner works alright during the evening and during cooler temperatures but struggles to reach the set temperature settings during hotter days.
