Effective air conditioning costs a staggering amount of money, according to homeowners. Even in the sweltering summer heat, your home is comfortable thanks to a dependable air conditioner.
Have you ever turned on your air conditioner and questioned, “why is my Air Conditioner not cooling the house?” AC problems can occur suddenly, and sometimes it’s hard to figure out what’s wrong.
Understanding some of the most typical AC issues will help you be more prepared for them when they do arise. Here are 11 of the most frequent problems when your air conditioner is not cooling the house.
1. Clogged Filters
Filter clogs may be the most typical cause of air conditioner issues. In addition to dirt, dust, and pollen, pet hair can block filters. Filters that are clogged prevent your unit’s ventilation. Your unit cannot efficiently cool your indoor space if impeded airflow. The operation of your unit’s indoor evaporator coil and outdoor condenser unit may also be hampered by clogs. The best approach to prevent such issues is to regularly clean filters and replace them when necessary. Filters should typically be changed every three months. If you have pets, you might need to replace them more frequently.
2. Low or Leaking Refrigerant
Air conditioning systems employ a substance called refrigerant to produce cool air. Moving over the indoor coil, the refrigerant absorbs heat to chill the air around it. The heat is subsequently expelled by going to the outdoor coil. Air is cooled using a variety of refrigerants, including Puron and Freon, which is still widely used but have been phased out. When the refrigerant level is low, your HVAC system may have trouble cooling your house. The system’s low refrigerant level may be due, among other things, to undercharging during installation. The system may have a leak someplace, which is the second explanation. If this is the case, you must get expert assistance right away. Both the environment and your health are at risk when refrigerant leaks. Even though it’s uncommon, refrigerant poisoning can happen if leaks are neglected for too long.
3. Dirty and Frozen Coils
The evaporator coil in your unit is kept clean by the filters in your unit, but problems might still arise over time. Installing a UV lamp can assist reduce the accumulation of dirt and enhance air quality. Because coils are constantly wet, mold and mildew can easily grow over time and cause coils to become unclean. Their capacity to function correctly will be harmed by this accumulation. Additionally, coils can overheat and stop working, particularly if the system is low on refrigerant.
4. Leaking Air
Over time, ductwork degrades. It can also be harmed by vermin and poor installation. It’s also possible for cable companies, plumbers, and home improvement specialists to unintentionally harm ductwork. These are the most frequent reasons for air leaks resulting from a heated house. Any leaks will restrict the amount of cold air entering your home because air ducts transport cooled air throughout it.
5. Compressor Isn’t Running
The compressor is the engine of your appliance. It transfers coolant back and forth between the indoor and exterior coils. If the compressor is destroyed, the system as a whole won’t be able to properly chill air. It’s possible that other, less expensive, and smaller-sized elements have failed in place of the compressor. A couple of examples are replacing the capacitor or other hard-start components that keep the compressor going. If your condensate drain is blocked and your system contains a ceiling saver mechanism, or float switch, that stops water leaks in your house, the compressor may also shut off. The best way to fix compressor issues is to replace them. Because compressors can be very pricey, you might wish to replace the entire outdoor equipment if you don’t have a warranty.
6. Exterior Fan Motor Problems
A fan inside the condenser unit moves the heated air from inside your house. The fan may experience problems, which could lead to an overheated compressor. In this situation, it is advisable to have a specialist investigate and resolve the issue. The fan won’t function if the fan motor fails, which will cause the device to overheat and shut down.
7. Thermostat Problems
The thermostat in your appliance measures the air temperature inside and changes it to meet your preset preferences. Your unit’s overall functionality may suffer if your thermostat isn’t working properly. Although it happens occasionally, fixing a broken thermostat is simple. Your settings may cause some problems; therefore, checking them may help. Try replacing the batteries if your thermostat is battery-operated. Some more recent smart thermostats may benefit from a hard restart. For the thermostat to reboot entails unplugging it first, then plugging it back in. If the thermostat appears frozen, doing this can be a quick repair.
8. Blocked Registers
Registers can also become dirty with time, much like filters, especially if you neglect to clean them frequently. Sometimes furniture inadvertently blocks registers or is purposefully closed off because a room isn’t being used. However, clogged or dirty registers prevent airflow, making your unit work harder. This raises your energy costs and makes it difficult for your air conditioner to adequately chill your house. This frequent issue is simple to resolve. Remove the registers, vacuum or wash them, then unblock or open any further registers.
9. Extra Heat From Nearby Appliances
Electrical items such as computers, TVs, lamps, and other devices can become very warm. Your thermostat’s functionality will be affected if appliances that give off heat are placed too close to it. Make sure there is enough space between the thermostat and any appliances that are producing too much heat.
10. Heat From the Sun
If your thermostat is exposed to direct sunlight, the increased heat may cause the device to malfunction. Keep your blinds or shades closed to lessen the heat burden on your home during particularly hot days.
11. Lack of Maintenance
A frequent cause of your air conditioner not cooling is inadequate maintenance. A reputable business should do regular check-ups twice a year, in the spring and the fall. A technician will examine your appliance, spot any possible problems, and take care of them before they require costly repairs.
