Is your air conditioner system not turning off on its own? Your home may begin to feel like an ice box, yet the air conditioner keeps on running. This is a major concern. When an air conditioner runs constantly it can run up your power bill very fast and lead to an expensive bill at the end of the month. Not only is the air conditioner hurting your wallet, but it will eventually damage itself as well. When an air conditioner system continually runs, there is a problem that needs to be corrected immediately. Hal Mechanical will help walk you through and troubleshoot this problem and let you know when to contact the professionals.
Should AC Fan Thermostat Setting Be on Auto or On?
Before you call up the professionals your first step is to check the thermostat setting. If the thermostat has been set to “On” then it will simply run and run. The “on” setting should never be used for daily use. Make sure the thermostat is set to “Auto”. This will ensure the air conditioner switches off when the desired temperature is met inside the home. At times the thermostat can malfunction and cause the air conditioner to keep on running. When a thermostat malfunctions it is time to replace the thermostat. However, it may be hard to determine if the thermostat is malfunctioning or if it is due to another problem.
Stuck AC Relay Switch
One common culprit that can cause the air conditioner to run constantly is a stuck relay. An air conditioner system is full of relays as the relays control the flow of power to the electrical components. At times the relay can get stuck which keeps power to the air conditioner running. This forces it to keep on working. Each relay will need to be inspected and tested to determine which one is stuck. The electrical relay or the capacitors may need to be replaced to correct the problem.
Clogged Air Filters, Dirty Coils or Ductwork Leak
In some cases an air conditioner system may seem like it is stuck on when that not the case. When the home isn’t cooling down on the inside, the air conditioner will run until the inside of the home is cooled. There can be many reasons why the home may not be cooling down. It can be due to an air flow restriction such as dirty coils or air filters. If the air conditioner is running constantly and the home is warm inside, check the air filters first. If the air filters are clean then the coil may require cleaning as well. At times there could also be an air leak which is preventing the inside of the home from cooling down. The air duct system will need to be checked for air leaks to determine if that is the cause. The air leak may even be due to proper insulation or there is a major leak from doors and windows.
