In winter, we keep the windows and doors shut, run the furnace all the time, use our fireplaces and create really dry air inside our homes. That warm and toasty home feels good when it’s cold outside. But here are some signs the air in your home is too dry:

Given the dirty nature of bathrooms, and toilets in particular, all homeowners want to find fast and easy ways to clean in these spaces. That’s why many choose to use the drop-in toilet cleaners that often come in the form of bleach-chlorine tablets. These tablets may seem like simple solutions, but they are often more trouble — and damage-causing — than they are worth.
If you use drop-in toilet cleaner tablets, we recommend you change to a different method for keeping your toilet bowl clean. You may like the fresh blue look of the water when using in-tank tablets, but you are actually damaging your toilet — and the long-term cost of repairs and replacements to your toilet far outweigh the short-term ease of dropping in a cleaning solution.
Here’s a look at how these drop-in tablets came to be, why they are harmful and what you can choose to do as an alternative.
Air conditioning is a convenience we rely on during the hottest days of summer and — for those of us who live in the Southern United States — for many months of the year. While these useful appliances don’t usually give us any trouble, they are also known to leak, which can cause extensive water damage to your home. In this guide, we’ll teach you how to easily prevent this potentially catastrophic situation with a simple, affordable and easily installable device called an AC float switch or safety switch.
How Do Air Conditioning Units Work?
Most air conditioners serve two primary functions — Removing heat for the air and dehumidifying that air. We’ll briefly describe each of these functions below:
Air conditioners remove heat from the indoor air by making use of a remarkable law in physics. When a liquid turns into a gas — a process known as phase conversion — it absorbs heat. An air conditioning unit takes advantage of this law by forcing certain chemical compounds to evaporate and condense over and over within a coil system.
The chemical compounds used in this process are called refrigerants, which have properties that allow them to evaporate at fairly low temperatures. Air conditioning units are equipped with fans that bring in the relatively warm air from the surrounding environment and move it over these coils filled with cold refrigerant, which are known as evaporator coils. Central air conditioners contain entire duct systems that funnel air to and from these coils.
This cooling cycle consists of two main stages:
- The refrigerant is converted to a gas: When warm air flows past these low-pressure, cold evaporator coils, the heat from the air is absorbed by the refrigerant inside the coils as the refrigerant converts from liquid to gas.
- Compression and conversion back to liquid: To continue cooling efficiently, air conditioners must convert these refrigerant gases back into a liquid, which they accomplish with a compressor. This compressor puts the refrigerant gas under high pressure, which creates undesired heat. The heat that results from compressing this gas is then channeled outside the building with the help of another fan and another set of coils known as condenser coils. This causes the refrigerant gas to cool and condense back into a liquid, and then the cycle starts over.
2. Removing Moisture
In addition to removing heat from the indoor air, most air conditioners also serve a second function — removing moisture from the air as it passes through the evaporator coil. As you now know, when warm air is moved over the evaporator coils and the refrigerant liquid inside evaporates, the surrounding air cools. As this air cools, moisture from the air will condense on the outside of the evaporator coils.To get rid of this moisture, air conditioning equipment contains drain pipes that allows the collected water inside the unit to drain. The water runs down the evaporator coil to a drip pan that temporarily contains the water until it goes down the drain.
What Is a Wet Switch/Float Switch?
Every once in a while, however, the drain pipes become clogged with debris and dirt, in which case they will no longer be able to effectively remove the water. Considering that a single HVAC unit can collect up to 20 gallons of condensed water a day, it’s not hard to imagine the damage that could occur if the water could not be adequately drained.
An HVAC wet switch/float switch, also known as a condensate overflow switch, serves to prevent this pan from overflowing if the AC drain stops working properly. The switch is activated when the level of the water in the pan comes above a certain point, causing the switch mechanism to trip/float to rise. When this happens, the switch will then send a message to the AC unit, and it will shut off, stopping the phase conversion and creation of condensation. At this point, a technician can locate and fix the source of the leak before water damage occurs.
Where Is the Wet Switch/Float Switch Located?
The location of the wet switch/float switch depends on the orientation of your HVAC equipment. Horizontal units typically have a secondary drip pan, which is found under the unit to prevent excess condensation from doing damage. The wet switch/float switch is attached to this secondary drip pan.
For vertical units or horizontal ones that don’t have a secondary drip pan, you can install a float switch on the PVC drain pipe of the unit, which will become activated if the flow of water becomes obstructed. Some HVAC equipment have a condensate pump installed with it, which the condensation drains into from the AC equipment and is pumped out rather than letting gravity drain it. These pumps also come equipped with a mechanism that resembles a float switch and works in the same way by shutting off the equipment and thereby preventing serious water damage.
Why Do I Need a Wet Switch/Float Switch? What Benefits Does It Provide?
Regardless of the location of your AC, it is critical to have a wet switch/float switch, or, depending on the type of unit, a condensate pump. An AC wet switch/float switch provides the following benefits:
- Reduce or prevent water damage: This safety switch will turn off the compressor, which, as you learned above, is in charge of the AC unit’s condensation process. By installing an AC wet switch/float switch, you’re avoiding what could be a disastrous event.
- Prevent dangerous mold growth: As any homeowner knows, areas that collect moisture are susceptible to mold. If not prevented from leaking moisture can get into unnoticed areas and microbial spores can grow and spread to other nearby areas such as the wall. Mold is not just an eyesore, but can also be foul-smelling and endanger the health of those who breathe it in. If your AC equipment is leaky, mold removal is an issue you might be forced to deal with. Of course, by installing an AC wet switch/float switch, you’ll no longer have to worry about this happening in the first place.
- Save money: Water can cause more damage than you might imagine. A leaky pan or drainage pipe can cause serious structural damage. It may leak into a nearby wall, ruining your AC unit and the wall as well. Installing this simple, affordable switch may save you thousands of dollars worth of damage.
To give you a better idea of how destructive water damage can be, keep in mind that the average cost for drying your property out from a water leak that is “clean,” which means no other damage occurred, is $2,700. The average cost of drying out a home and fixing the damage done to carpeting, drywall and other areas is around $7,500. Costs can be even higher depending on how much water is involved and how extensive the damage is.
While a leak may seem like just an inconvenience, a leak can severely damage a home if not dealt with quickly. In addition to damaging areas like drywall and carpeting, it may also eventually lead to:
- Fire caused by water coming in contact with electrical sources
- Rotting or softening of wood and various other organic materials
- Staining as a result of particles or minerals found in the water that seeps into wood, stone and other porous materials.
Wet Switch or Float Switch?
A common alternative to the float switch is a wet switch, which also detects when condensate water overflows. However, it does this in a different way. Unlike float switches, wet switches are normally placed in a secondary drain pan, which is usually dry. If there is an overflow in the primary pan, it will flow over into the second one. The wet switch, upon detecting this moisture, will turn off the unit to prevent water damage.
