Do not get stuck on a hot and humid day with an air conditioner that is not working!
When your air conditioner stops working on a hot and humid day, your day can easily be ruined. To troubleshoot common air conditioner problems, first check the basic settings, fuses, and circuit breakers.
Resetting the Circuit Breaker and Basic Settings
Prior to performing any resets on the circuit breaker or changing any settings, let the unit cool down for about five minutes. When temperature and humidity levels are high, a central air conditioner may tend to stop. This is generally caused by the high pressure limit switch which is actuated by the excessive pressure of the refrigerant flowing out of the compressor. This can be corrected by simply resetting the high pressure switch which is located on the control panel. During hot and humid days, the condensate flow is higher. Check that the condensate drain is clear and not chocked with dirt or debris.
A refrigerant leak is another common problem encountered on air conditioners. An air conditioner unit, when low on refrigerant, will continue to perform lower than the designed output and the cooling will not be effective. Check whether the refrigerant has become lower with time. The loss of refrigerant may be due to a leak in the system and must be thoroughly checked by a St. Louis HVAC company.
Any leaks must be fixed and the system must be pressure tested prior to charging the refrigerant. The refrigerant must be maintained at an optimum level and should never be undercharged or overcharged. The optimum amount or level of refrigerant is provided on the manufacturer’s manual and correct charge ensures good performance and high efficiency of the unit.
Regular HVAC Maintenance
Routine HVAC maintenance is the key for the proper functioning of your air conditioner unit. If the air conditioner is not maintained as per the stated schedule and the air filters and the coils are left dirty, the performance of the unit will be affected. Dust accumulation and inadequate maintenance can result in premature failure of the compressor or fan.
During a maintenance call, ensure that the control panel and the wire contacts are checked thoroughly as the connections tend to wear out due to corrosion. The frequent switching on and off in oversized units exert pressure on the electrical controls and terminals and they may break down causing the unit to stop.
