Just Do It Yourself : 5 Reasons Your AC Is Not Cooling Your House

You've just come home from work or a long trip and the house feels too hot. After a quick check, you discover that the Air Conditioner is the source of the problem. Either it's not working at all or performing efficiently - as always. What could have gone amiss?

5 Possibilities

The following are five possibilities;

1. Thermostat Issues
The first place to check is the thermostat. This especially applies if the AC isn't cooling fast enough. It could be as simple as a wrong thermostat setting or as bad as a malfunctioned thermostat. If the setting is wrong, simply dial in the new desired temperature. However, if the thermostat display is blank, then the device might have failed. Perhaps the battery has died or the device has malfunctioned. Try replacing the batteries. If it still doesn't want, call an HVAC repair specialist.

2. Dirty air filter
It's not uncommon to find that your AC air filter has collected too much dust which might cause it to block. A blocked filter only allows a small amount of air to pass through. Remember that the air coming through it will also be dirty and thus unhealthy. Sometimes, it may not allow air to pass through at all. You can attempt cleaning the filter to improve performance. However, the best solution is to replace the dirty filter with a new one. This will not only boost your AC's performance but also improve the quality of indoor air.

3. Blocked condenser unit
ACs work by absorbing the heat in the rooms via an evaporator and dissipating it via a condenser unit. It means that the condenser unit has to be in perfect shape for the AC to optimally cool your house. Unfortunately, the condenser unit rarely gets the necessary attention because it's located outside the AC. If you suspect that the condenser unit might be the cause of a malfunctioned or poorly performing AC, take it outside in the open and thoroughly clean it. If the problem persists, call a professional.

4. Low refrigerant
To absorb heat from your rooms, the AC uses a special kind of fluid known as a refrigerant. It would be helpful if you had a good level of refrigerant in your AC for optimal functioning. If the refrigerant level goes below a certain point, the system may not be able to cool your home as desired. You'll know that refrigerant level is low when you see ice on the refrigerant lines, hear a hissing noise, or experience ineffective cooling on hot days.

5. Frozen air handlers
The air handler is located behind the air filter inside the AC's evaporator coils. Whenever they freeze, they block the air inside your home from coming into contact with the evaporator coils or the refrigerant. This, in turn, prevents air from being cooled, resulting in rather hot indoors. Also, it can prevent the AC from dehumidifying your air. To diagnose your air handler, remove the air filter, take out the air handler, and let it defrost for 24 hours.

Don't hesitate to call an HVAC repair professional whenever you run into trouble. Although DIY is cool, professional repair guarantees long-term results.
