Spotting a Broken Condensate Float Switch

During the cooling season, your AC is put under the stress and strain of competing with the Florida heat and humidity. Considering how hot it is outside, and what your AC has to do to keep your home cool and comfortable, it’s no wonder that it may develop a problem at some point. Of the various things that can go wrong, a broken condensate float switch is relatively minor, but it has important implications for other parts of the system. During the cooling season, you need to make sure that every aspect of your system is in good working order. At Astro Air, we want your home to be comfortable. You can call us for air conditioning repair service in West Palm Beach, FL any time.

In order to understand what a condensate float switch is and how it works, it’s necessary to understand the role of the evaporator that sits in your indoor air handler. The evaporator is a set of pyramid-shaped coils that circulate cool, liquid refrigerant that has come from the outdoor unit. As the blower pulls in your warm indoor air through the ducts, the refrigerant absorbs the heat from the air, which causes it to evaporate (hence the name!). This process causes the moisture in the air to condense, which leaves moisture on the outside of the coils. If this moisture were to collect in the indoor air handler, then it could cause damage to the blower motor or any other components.

There is a condensate drain pan fitted just below your evaporator coils that collects this condensation so that it doesn’t drip outside the indoor air handler or within it. This is connected to a drainpipe that leads to the other drains in your home. The condensate float switch is a device that shuts the system down when the level of the condensation in the pan becomes too high or begins to overflow. If you AC stops working or won’t turn on, the level of condensate might have triggered this switch, and you’ll want to call a professional to find out the source of the overflow. However, if there is a problem with the condensate switch itself, it can cause you AC to turn off for no reason. If the condensate switch is not working at all, it might fail to turn off your AC when the condensate is too high, which can cause water leaks and damage to your system. It’s a small but important part of your AC system, and one of the many things your technician will check during your annual maintenance visit.
