Condensation On My Air Conditioner Unit: Should I Be Worried?

Condensation On My Air Conditioner Unit: Should I Be Worried?When something is wrong with your air conditioner, it will let you know in a number of different ways. Maybe you have a gut feeling your energy bills are too high, and you certainly know when your home is uncomfortable. Another sign your air conditioner is failing is condensation collecting on and/or around it. Switch the thermostat and your panic buttons off, and keep reading before you make your next call.

What Harm is a Little Water?

Water condensation on your air conditioner’s evaporator coil is normal. However, as you’ve realized, water leaking from your air conditioner onto your floor is not acceptable. Depending on where your indoor A/C unit is located, condensate leaks may cause damage to your ceiling, walls, flooring and/or other building materials and property.

What to Do?

In order to know what to do about a leaky A/C, it’s helpful to know how condensation forms and the most common reasons why it’s leaking. Condensation forms as a result of water vapor in warm airflow being pulled across the cold evaporator coil. Under normal conditions, the condensate drips into a pan, flows down the drain and through a tube away from your home. End of story — unless your A/C unit is experiencing these problems:

  • A blockage in the drain tube is causing an overflow. Your HVAC technician uses either a powerful blower or heavy-duty vacuum to push or pull the blockage through. Then, the line is chemically treated.
  • The float switch has malfunctioned. Some air conditioners have a float switch that turns off the unit when water fills the drip pan too high. If your A/C is equipped with such a device, but it’s not working, it needs to be repaired or replaced.
  • The drip pan has rusted through or it has broken. Your technician can simply replace the drip pan.

Ask your HVAC technician or plumber if your A/C has a float switch. If not, you’d be wise to have one installed in the drain trap. For assistance repairing air conditioner condensation problems in your Portland home, please contact the professionals at Roth Heating & Cooling today.

Discover Creative Ways to Hide Your Outdoor HVAC Unit

Discover Creative Ways to Hide Your Outdoor HVAC UnitLet’s face it, your outdoor HVAC unit is not the most attractive feature on your property. Also known as the condensing unit, the outdoor component of your HVAC system is installed where it is for optimal performance, not for how it meshes with your landscaping design. Fortunately there are ways to make the outdoor unit less obtrusive. Here’s how.


The simplest way to hide the outdoor HVAC unit is to plant around it, but be careful what you plant. Choose ornamental grasses that don’t grow too tall and that are easily managed. Some smaller-sized shrubs are fine, but avoid bushes that might interfere when your HVAC tech works on the unit, like thorny rosebushes or prickly holly. Keep shrubs trimmed back so there’s a 2- to 3-foot clear space around the unit for good ventilation.

Do not plant trees or shrubs that are likely to drop seeds, fruit, or debris that might clog the venting around the unit’s metal cage. Plant debris can close the vents and restrict airflow around the unit. Good airflow ensures that the condenser can exhaust heat properly.


Erecting a fence around the condensing unit is an easy way to hide it. Leave at least 2 feet around the condenser and an entrance/exit to the unit for your technician. Whatever material you choose for the fence should permit airflow. Check with your local zoning authority to make sure you comply with all regulations for fencing.

Building a dedicated, well-ventilated structure around the unit is another option. A utility closet, constructed with materials that harmonize well with your landscaping, could be erected to house tools as well as the condensing unit. The roof of the structure should be at least 5 to 6 feet above the unit and well-ventilated.

A trellis is another easy solution for keeping the unit out of sight. Plant attractive vines such as clematis, passionflower, or trumpet vine to grow up the trellis.
