One of the most commonly encountered problems residential owners face is a leaky air conditioner. In the advent that you find yourself in a scenario like this, it's important that you turn off your unit and contact 72 Degrees Air Conditioning and Heating as soon as possible for service in Fredericksburg and Kerrville. Water emanating from an HVAC unit can cause damage to the electrical components of the unit. In this overview, we will take a look at some of the reasons why an HVAC unit leaks as well as the importance of contacting a professional HVAC Company for repairs.
Damages To The Joint
When the joint between the unit and the drain line gets damaged, a leak may occur. This usually happens when the unit has been in use for several years. The joint essentially becomes worn out over time, and it is extremely difficult for a homeowner to identify and replace the joint.
In some instances, a unit may leak as a result of improper installation. For instance, a cooling unit needs to be installed in a way that allows the front end of it to be a little higher than the rear end. A basic rule of thumb that most professionals follow is a one-inch difference in elevation from the front to the rear end of the unit. Leaking occurs when there is less than a one-inch difference between the elevation of the front and back end of an HVAC unit.
Once a unit has been installed, it needs to be sealed to prevent cold air from escaping the facility in which the unit is placed in. In some situations, a unit may leak because it was not properly sealed from the outside. If it's not sealed correctly, warm air surrounding the outside of the unit can enter the unit and subsequently get condensed as a result of the cold air that's generated by the unit. Eventually, this condensation leads to a build-up of moisture on the inside of the unit which causes it to leak onto the outside of the unit.
Rested Drain Pan
Some units may leak as a result of an old or rusted drain pan which has surpassed its life expectancy. This typically occurs in older units that have been in use for more than 5-10 years. Drain pans are made of different types of metal sheets. Over time, as the unit is being used, these metal sheets eventually become rusted and worn out. At some point, the metal sheets may become so rusted that small holes form in several areas of the drain pan, which leads to leaks.
Each unit is outfitted with drain holes which are located at the rear end of it. Sometimes these drain holes get clogged with dirt, dust and other small debris. This blockage prevents the unit from draining moisture. This moisture will instead build up and cause water leakage. This is why many manufacturers proclaim that units need to be cleaned at least once per year by a Fredericksburg Air Conditioning Repair expert.
