Why is Ac Running but Not Cooling?
An air conditioner is one of the most integral parts of home appliances because it keeps your home cool and comfortable. About 87% of the US population spends on efficient air conditioning. However, an unexpected AC problem during peak summer days can cause convenience and costly repairs or replacements. While most issues require professional help from experts in air conditioning repair in Sacramento, homeowners with basic knowledge can try the fixes. If you are unsure, consulting with an expert is the best solution. There are several reasons the AC is not cooling indoors.
Here are the Possible Causes of a Malfunctioned AC
Dirty Evaporator Coil
The evaporator coil helps transfer heat from the interior to the refrigerant. Over time, the coil gets clogged with debris or mold, preventing efficient heat transfer from your house and resulting in no cold air. Sometimes, a frozen evaporator coil can also cause your AC to malfunction. Consulting with an expert in appliance repair in Sacramento is the best way to deal with the problem.
Clogged Air Filter
Blocked air filters prevent the smooth delivery of cold air output. If your AC blows hot air, a clogged air filter may be the problem. Cleaning your AC filters periodically is necessary to maintain appliance efficiency. Also, replace your air filters at least once a month for the smooth function of your air conditioner.
Incorrect Thermostat Setting
Homeowners ignore their thermostat settings which may be set to heat instead of cool. Consequently, the air coming out of your vents will be warm, increasing the indoor temperature. Another thermostat issue may be its unusual temperature. Check whether the thermostat is exposed to direct sunlight because it may prevent blowing cold air.
Refrigerant Leak
Refrigerant allows heat transfer from your home to the outer condenser unit. A leaky refrigerant can switch to low-pressure safety affecting its function to move heat out of the house. Refrigerant leaks require professional assistance because they may cause health problems.
Leaky Ducts
Leaky ducts are caused by pest infestation, mold growth, improper installation, or other factors. Ducts distribute the cool air throughout your house. Damaged ductwork affects the efficiency of your AC system, increasing utility bills. EPA recommends regular cleaning of ductwork to maintain the system’s efficiency.
Other Reasons for Malfunctioned AC Include
- Damaged Heat Pump
- Compressor Problems
- Insufficient Coolant
- Undersized AC
- Frozen Coil
- Damaged Indoor Fan
- High Atmospheric Temperature
Conclusion
Although a machine or an appliance can malfunction at any time, maintaining it can prolong its lifespan, providing convenience and preventing overspending on avoidable repairs or replacements. If you cannot fix the problem using the DIY approach, contacting the expert is the best way to deal with the problem because you don’t want to sustain injuries. Consult an HVAC professional to maintain the efficiency of your AC system.
