2 Signs There Is Too Much Condensation Accumulating Inside Your Home's Central Air Conditioning System


As part of its function, your home's central air conditioning system does more than cool the air. It also pulls the moisture out of the air to help keep your house from feeling muggy, especially on days when the outdoor humidity levels are high. 

However, when there is an issue with the A/C unit, such as a blocked condensate line or a problem with the evaporator coils, the moisture will build up within the unit and cause issues with running the system. Below are a couple of signs to look out for indicating that there is too much condensation accumulating inside your home's central A/C system and should be inspected by a professional repair technician.

1. Ice Forms on the Surfaces of the Evaporator Coils, Making It Necessary to Thaw Out the A/C Unit Because It Keeps Freezing Up

One sign that too much condensation is accumulating inside your home's A/C system is when the ice starts forming on the surfaces of the evaporator coils. These coils contain refrigerant that cools the air while pulling heat from it.

When there is too much moisture in the system, it will settle on the surfaces of the coils where the water will freeze. As more condensation forms, the ice will continue to grow, and the unit will stop working until it is turned off and thawed out. 

2. A/C System Shuts down Because the Excess Moisture Has Triggered the Float Switch to Prevent Further Damage to the Internal Components

Another sign that condensation is building up within the air conditioning system is when it keeps shutting down because the float switch is triggered. As part of the system's safety features, the float switch will detect an overabundance of moisture, usually from an overflowing drip pan or blocked condensate line.

If too much water is detected, the float switch will trigger and shut off the system to keep it from sustaining damage. You will need to have a repair technician find and fix the cause of the excess water and reset the float switch to get the system to turn back on.

When your central air conditioning system keeps freezing up or shutting down because of excessive condensation, there may be an issue with the drip pan overflowing, the evaporator coils may be damaged, or the condensate line is blocked. Until the underlying problem is solved by a professional repair technician, your air conditioner will continue to have problems. Contact an HVAC contractor who offers air conditioning repair services to have them check out the system and make any necessary repairs.

Cool off Your AC Bill

Every summer, I agonized over energy bills that would shoot into the stratosphere as a result of my efforts to keep cool in the heat. Every time I turned the temperature down, my bills increased. This summer, I decided to take some of the control over my energy bill back. I installed reflective film on my windows that reduced the amount of light and heat coming into the house. I started serving more cold meals or asking my husband to barbecue outside, so that my air conditioner didn't have to compete with the hot stove, and I started doing laundry at night to reduce appliance heat in the house at peak times. I also had ceiling fans installed. So far, the difference in my bill has been tremendous. This blog is a way for me to explore other ways to reduce energy drain during the summer months.
