Your air conditioning and commercial plumbing in Harvey systems are interconnected in order to contain moisture, humidity, and precipitation. Mold and mildew can be caused by leaks, flooding, and excess moisture, particularly in our humid climate. Extra water can cause significant damage.  


Methods for Detecting Water Leaks to Minimize Damage 

Sometimes water damage is obvious because water is flowing through a wall or ceiling. The first step is to turn off the water supply to the residence. Know the location and operation of your home's water shut-off valve in the event of a water leak. 



Frequently, water breaches are less noticeable. Here are some approaches to check for damage: 


Investigate your water account. Is it significantly higher than normal without explanation? 

Be vigilant and keep an eye out for stains on the carpet, walls, and ceilings, particularly around appliances, faucets, and restrooms. 

Is there a musty or stale odor in the house that cannot be explained? 

Is your flooring warping or not lying flat? 

Do you perceive a dripping sound but cannot determine its source? 

Why is the paint oozing and the wallpaper peeling? 

Do plumbing fixtures exhibit signs of moisture or corrosion? 

Does water drip from the condensate drain outside your residence when your air conditioner is running? 

The Upkeep of Your HVAC Condensate Drain 


Examine the Condensate Drain Outside the Residence. 


The initial step in maintaining your condensate drain is to locate the drain's release point. This drain should be dripping during hot, humid Gulf Coast weather and when the air conditioner is operating. This demonstrates that it is removing moisture from the air.  


This discharge should not leak when the air conditioner is turned off.  


If your drain is not dripping while your air conditioner is operating, it may be obstructed. 


If you cannot locate an exterior drain, your condensate drain may be connected to your plumbing system. This will be discussed in greater detail later in the article. 


How to Maintain a Clean Condensate Drain Inspect and maintain your HVAC condensate drain next to your domestic evaporator coil by pouring a half-cup of vinegar, not bleach, into the condensate drain every three months. 


In numerous residences in our region, the drain's opening is situated in the attic. Sometimes it will be in an entryway closet. 



Even remembering to do it once or twice per year is preferable to never doing it. 


If this form of maintenance is not your cup of tea, check with your HVAC contractor to see if condensate drain maintenance is included in the regular maintenance plan.  


Mount a Float Switch 

Install a float switch or ceiling saver switch if you do not already have one. In the event of a clogged drain and a full drain basin, these switches shut off the air conditioner. 


Your HVAC contractor will gladly demonstrate where the drain is, how to maintain it, and whether a drain pan float valve would be advantageous. 


Depending on the municipal code in your area, the installation of float switches is required for newer HVAC systems, so you may already have one or two!
