What Causes My AC System To Leak?

While it is summer, all you want to do is relax and make the most of your air conditioner. But, when disasters happen such as a leak in your cooling system, you suddenly find yourself rushing to know what causes it.

Stop making guesses! Instead, get to know these top reasons for air conditioner leaks.

  • Clogged Drain Line

One of the most common reasons for A/C leaks is a blocked drain line. Any blockage in the drain hole such as mold, insects, and dirt cause the water to go back into the system. Unclogging it may take time even when you use a high-performance vacuum. A quick way to unclog it and get your system back to work is to call professionals to suck the obstacle out.

  • Broken Sump Pump

If your A/C unit is installed in the basement, you can easily figure out why leaks happen. You can take a wild guess by thinking that the cause is a broken sump pump. And, you are right! Even the smallest crack on the pump prevents it from doing its job. Instead of pumping the water outside, it does the opposite. You might have it repaired or replaced depending on the severity of the damage.

  • Frozen Evaporator Coils

How is this possible when the sun’s all out? Leakage on air conditioners due to frozen evaporator coils is 100% possible because of clogged air filters. Dirt and dust that are accumulated in the evaporator coils block the air from passing through, causing the coil to freeze up. When airflow is constrained, ice will develop producing droplets of water over time. Other causes of freezing evaporator coils are damaged blower motors and blocked registers or vents.

  • Incorrect A/C Installation

Check your unit if it is positioned on the right spot or level. Doing this will assure you if your air conditioner is installed correctly (as required). Leaks can happen if installation is done in the wrong way. Let the experts do a complete examination on the system to guarantee a properly installed and designed A/C unit.

  • Excessive Pressure

Clogged or closed vents cause pressure to build up in your air conditioner. When there is too much pressure on the unit, water may begin to leak out. To avoid this scenario, make sure to leave your vents free from any blockage.

Commercial HVAC Maintenance Checklist for Summer

Your commercial HVAC system could be one of your biggest investments.  As the owner, you must be spending a large chunk of money each year on facility costs. In the US, both industrial and commercial facilities spend approximately $400 billion on energy costs annually. This figure can increase at a massive amount with a defective and inefficient HVAC system.

If you want to generate savings on facility and energy costs, a preventive HVAC maintenance is a key. Here is a maintenance checklist perfect for your commercial heating and cooling system.

Indoor Components

  • Lubricate or replace belts if necessary.
  • Check and clean fan blower to prevent dust and dirt buildup.
  • Clean the combustion blower housing to allow a smooth and fresh flow of air.
  • Clear evaporator coils, condensate lines, and drip pan.
  • Inspect and clean the burner assembly, ignition system, and heat exchanger.
  • Test all safety controls.
  • Check the wiring, connections, and control box for dislocation and wear. See if they are tightened and in good condition.
  • Replace or clean your air filters.
  • Examine your duct system for rodents, pests, moisture or dust formation.

Outdoor Components

  • Make sure to clear the condensate lines and drain pans of any obstructions such as bushes, leaves, trunks and all sort of dirt.
  • Fence the compressor to avoid wear and damage caused by outdoor and natural elements.
  • Inspect and lubricate fan motors and blades.
  • Look at all switches, connections, wirings and safety controls.
  • Measure the refrigerant level. Recharge if needed.

Cleaning and Replacing of Air Filters

Experts advise having air filters of commercial HVAC system inspected at least twice a month. Scheduling as complete inspection prevents the dust, dirt, and debris from clogging the filters. Change the filters at thrice a year or as per your manufacturer’s instruction. Or, do it if necessary. Clean air filters lower your electric cost up to 15%.

Checking of HVAC  System

Let your commercial HVAC contractor perform a periodic check on the system monthly or when needed. Include your thermostat on the inspection to know if it is operating efficiently this season. Repair or replace the thermostat or any parts of the system with damage or tear. Also, check for moisture and mold growth on both indoor and outdoor components.
