Scott-Lee Heating will help improve the comfort level of your home environment this summer.
In the hot summer months, the last thing one wants is for the air conditioner to blow warm air and make the inside of the home as unpleasant as the weather outside. Hot or warm air from the air conditioner can be a reason for concern and should be checked. There are many reasons that could cause the air conditioner to blow warm air, of which some can be easy to address. However, some others need professional help and troubleshooting at the hands of a trained, qualified and experienced St. Louis HVAC technician.
The following are some of commonly known reasons for warm air blowing out of an air conditioner.
Most modern HVAC’s have digital programmable thermostat settings and at times, these can get confusing for new HVAC owners to understand. HVAC owners should use and check the instruction manual while using the air conditioner. One should make sure to check if the fan setting is set to ‘ON’. This setting allows the fan to run even when the AC is off, blowing normal air into the vents. When the AC is not on, this ‘normal’ air may feel warm.
Clogged Air Filters
Clogged air filters can severely hamper the functioning of the air conditioner causing it to over use energy and reduce efficiency. Moreover, it can lead to less cooling due to inefficient cooling. The air conditioning system should be maintained on the outside as well as the inside. A homeowner should ensure that the unit does not accumulate dirt and debris and is regularly cleaned.
Blown-Out Breaker Switch
Warm air issuing from the AC also becomes a concern if one part of the air conditioner’s unit is not functioning and the other one is. This is often found when there is a power outage and power supply to the outer unit is cut by a tripped breaker switch. It can be rectified by locating the tripped switch in the electrical breaker and flip it back on. However, if the problem persists, it could indicate a more serious electrical issue.
Refrigerant leakage is also another reason for warm air blowing from the AC. In such a case, neither is adding more refrigerant a solution, nor is a short term fix like using sealant to fix the leak a sustainable plan. Refrigerant leaks should always be repaired by a trained and qualified HVAC technician, who will know the right method and use the correct options to stop refrigerant leaks.
Frozen AC Unit
A frozen AC unit will stop the AC from functioning altogether. This often happens when there is either a refrigerant leak or due to a clogged air filter that will lead to a frozen evaporator coil. If left unchecked, this can cause permanent damage to the air conditioner.
