You may be wondering how does condensate safety switch work? Let’s break it down. Overtime when slime, algae, mildew and/or bacteria accumulates in your drain line, it can eventually block the water from draining properly. A clogged drainpipe can create a dangerous mechanical problem for the air conditioner the longer it goes unaddressed.
If your indoor unit is installed horizontally in your attic, there may be an auxiliary overflow pan to catch any condensation drip if the main condensate line is backed up. If it doesn’t have the secondary tray or if the auxiliary line becomes blocked, the water will eventually overflow causing damage to your floors, sheetrock, walls, and ceilings of your Sacramento home. By the time you notice a leak in an indoor unit, whether it’s been installed vertically or horizontally, the work will be both extensive and expensive to repair. HVAC replacement guidelines may require you to then purchase the safety switches to avoid the damage from happening again.
This is where the air conditioner safety switch comes into place. A condensate switch is a device that automatically shuts off your AC when condensation and moisture is detected at a certain level in your drain pan. A safety switch on AC unit can prevent a leak from happening after a signal is sent to the compressor unit to turn off. Deactivation of the compressor will bring the dripping to a halt as condensation will no longer form from a unit that is off.
A condensate safety switch is mounted on the side of your drain pan or directly on your secondary drain port on the evaporator coil. There’s a float inside the switch that will rise if the water level of the pan fills up, notifying you that there is an alarming amount of water that has built up. Whenever the switch closes, the contacts energize at a low voltage and send a signal to the control board to shut down operations. At a normal level the switch is open and it only closes when it needs to notify the unit to shut down because of the condensation level.
- Prevents a leak and overflow: Little to no moisture will accumulate in the drainage system because your system will be signaled to turn off once any condensation drippings trigger it.
- Saves money on costly home repairs: This device prevents any costly catastrophes of flooding, sheetrock, or unit to have to be replaced unnecessarily by water that could have been avoided.
- Provides 24 hour water damage protection in your attic, closet or garage ensuring that your secondary drain pan does not fill up with water.
- Peace of mind: Sleep comfortably on those warm California nights knowing that your AC will not become ruined by water damage.
Although there are many brands and variations of switches, they generally fall under two HVAC safety switch categories which are float or sensor. Both of them are prevention devices that provide protection for your HVAC unit.
A Float Switch is an ac safety switch that trips on when the water level reaches a certain point and sends a message to your AC unit to shut off. An HVAC technician will then be able to come in and find the source of the issue before any flooding takes place.
A Sensor Switch automatically turns your AC off once a few drops of water are detected. The couple droplets of water activate the switch to prevent any water damage, leaks or clogs. Switch installation can be on the inside or outside of the drain pan.
There are three primary locations where an AC system safety switch can be installed including the primary drain pan, secondary drain pan or the drain line. While installing a condensate switch on the primary drain may be sufficient for your home, depending on the size and location of your unit, you should consider having more than one backup.
For example, it is important to consider having a condensate switch connection on more than one of your drain pans to collect any water that overflows from the primary drain pan inside the AC. Having this additional protection will ease your mind.
Your Primary Drain Pan sits inside the air handler and your switch can be attached to the horizontal drain line coming from the main port. You can also install it in the secondary port (different from the secondary drain) or wherever space most clearly allows.
The Secondary Drain Pan is there to be reinforcement in case the primary drain pan fails to hold the excess water due to any clog or other reason. Installing a switch on the secondary pan will provide another layer of protection for your HVAC unit and home.
These switches shut off the system immediately and can be installed inside drain pans or be placed on the floor near your secondary pan for backup of any flood issues or water damage occurring.
The condensate drain switch (or multiple switches) you need will depend on a number of factors including the location and orientation or the air handler as well as your preference of protection.
A certified technician will be your best resource in determining the proper installation location.
