Condensate Concerns
Condensate water is a natural by-product of all air conditioning systems. This water is formed on the surface of the cooling coil in the attic as the warm air passes over the coil made cold by the refrigerant. This moisture "condenses" out of the air by the same process as moisture forms on a cold glass of liquid sitting in a room. Under normal circumstances this water is carried off into your house drainage system the same as water from a sink or shower. If water is dripping into the occupied areas of the house the probable causes are as follows:

Problem
Primary drain line stoppage-causing water to drain from secondary line usually located over a window in soffit.

Risks on non-repair
A drain stoppage in the secondary drain line would mean that there is no proper outlet for the flow of condensation from the cooling coil located in the attic. When the drains back up, the only available outlets are blocked and the water will overflow into the attic. There is a potential for significant ceiling damage.

Common or Uncommon
This is a common problem in the Dallas/Ft. Worth area. Generally, the drain is clogged by dust particles building up over a period of months. This may or may not become a recurring problem. Some homes require twice yearly regular maintenance and others may never have a detectable problem.

Recommended Solutions
Utilize Frymire Services for regular maintenance.
Have systems serviced by a professional heating and air-conditioning service company. Frymire Services Inc. follows the manufacturers’ installation instructions for condensate drain installation. All manufacturers recommend the condensate drains be installed with a trap of proper size and installed as close to coil as possible. All industry references to a vent tee state that it should be installed after the trap. The use of bleach or other caustic chemicals to clean drains are not recommended by manufacturers. Bleach is a powerful VOC (Volatile Organic Compound) and can be an irritant to persons with respiratory issues. Bleach is also been known to be corrosive and attack the fins of the evaporator coils. There are multiple causes related to condensate problems in HVAC systems which may include: contaminated evaporator coils, debris in drain pan, dirty blowers, dirty filters, improper refrigerant charge, and condensate drain termination problems, all of which would require a qualified service person to diagnose and repair. Frymire Services, Inc. recommends that regular inspection and maintenance be performed by a qualified HVAC service technician.
