It can be very concerning to see an appliance leaking water. On a hot humid day, no one wants to see an air conditioner leaking.
There can be several reasons why your air conditioner has dripping water.
A dirty air filter can cause your evaporator coils to freeze. Refrigerant goes through the evaporator coils and absorbs heat. When a dirty filter restricts the airflow, ice forms, and drips.
The first sign of a frozen evaporator can be warm air blowing into your home. Frozen evaporator coils can’t absorb heat from the house.
Turn off your HVAC unit if you notice ice build-up and dripping water. Other reasons your coils could be frozen are from blocked vents, faulty blower motor, or dirty coils.
Let the ice on the coils melt (this shouldn’t take long on a warm day), and then change your filters. If the filters don’t stop the ice and water on the coils, you might have a more serious problem.
If your HVAC unit is low on refrigerant, then it can also cause your evaporator coils to freeze.
There are a few easy signs that let you know the refrigerant is low:
- The air isn’t cooling
- You notice refrigerant leaking
- There’s a hissing sound coming from the unit
A refrigerant leak is a costly and complicated fix. Call an HVAC technician immediately if you suspect a leak.
Drain pans are located near the evaporator coils and catch any condensation from the HVAC unit. Sometimes they crack or overflow causing water to leak from your unit.
You might be able to fix a cracked drainpipe with sealant or use a wet-dry vac to empty a drip pan, but it’s best to let professionals evaluate problems.
Condensate Drain Line
If you start noticing water backing up into your home from the HVAC, then a common problem is a clogged condensate drain line.
Sludge, dirt, and mold are the most common culprits for these back-ups.
You can purchase special vacuums designed to unclog this line, but it might be easier to hire someone else to handle this.
Also, check the condensate pump. This pump pushes water outside away from the home, so if this pump breaks you will need a replacement.
How Much Water Should My Air Conditioner Be Leaking?
Don’t be alarmed every time you see water near your HVAC unit. Small amounts of water are normal during regular operation.
On especially hot days, expect a little more condensation to form and drip from your drain pipe.
Those who like to run the air conditioning constantly might also see higher amounts of water coming from the unit. Have annual inspections done to ensure everything is in working order.
