Below are some details about the most common air conditioner problems that occur and why they are happening. In most of these instances, other than in instances when you need to clean your unit to remove an obstruction, an air conditioning service technician will be necessary. However, being informed about what your problem will provide you a better description of the air conditioner or air conditioning system’s issues will assist you in providing useful information for your service technician to more quickly and easily diagnose the problem.
Power & Contactor Problems – If your outside air conditioning unit isn’t operating at all, the most culpable causes are that your unit is lacking power, has contactor issues, or it may even possibly have a broken thermostat.
Broken Thermostat – If your outdoor air conditioner isn’t providing enough cool air even if the unit is in operation, your thermostat could possibly be approaching the end of its shelf life.
Wiring Problems – Wires not installed by a professional or damaged air conditioning wiring can be a fire hazard in addition to causing other safety risks. Bad wiring can result in your unit not getting adequate power to operate effectively and can blow fuses or trip circuits.
Refrigerant Refills – Refrigerant is the chemical that chills the air inside your air conditioner or air conditioning system. If your refrigerant is insufficient you may either have a refrigerant-related issue. If you require a refrigerant recharge, it’s usually due to a leak, but not always. All refrigerant leaks must be found and fixed by a professional service technician.
Inoperable Outside Fan – Your air conditioning system’s outside fan has the role of carrying the hot air from inside your house to the outside. If the outside fan inside your unit isn’t working properly, the appropriate transfer of heat can’t happen. In addition, the air conditioner’s compressor can possibly overheat and set off the unit’s safety overload response or even cause damage inside the compressor.
It’s a good idea to inspect for a blown fuse or tripped circuit. If it is, once you’ve confirmed the blown fuse or tripped circuit, turn the unit back on to see if it start working. Additionally, it’s a possibility that the condenser is dirty. Cleaning the blockage might be a viable could be a solution. The unit’s condenser can get clogged by outdoor environmental debris.
Frozen Coil – If the coil in your outside air conditioning system freezes, this is often a sign that air-flow is obstructed. This can mean a dirty air filter or blocked return air duct-work. Frozen coils on an indoor air conditioner could be a signal of your unit being in need of refrigerant.
