Water leaks in your central air conditioning system

Leaking Water: Are you in the Toronto area and need Air Conditioner repair?

Living without an air conditioning during the Toronto summer heat is impossible. Knowing this, you’ve most likely done your research and invested in a high-quality energy efficient air conditioner, keeping your home nice and cool during the hottest summer months. However, even the high-quality air conditioner requires occasional repair. Broken air conditioner can be devastating hence, prevention is the best medicine. Make sure to take preventative steps to avoid unnecessary disappointment.

When exactly should you call a heating and cooling expert for an air conditioner repair?

One of the most common reasons to call a service technician when you find your air conditioner is leaking water.

The following issues can cause water leaks in your central AC system:

Clogged Drain Line

A clogged condensate drain pipe can make your AC system’s drain pan overflow. This is probably the most frequent cause of water leakage from a central AC system, bringing many service calls to HVAC professionals as summer temperatures rise. Drain lines can become clogged with dirt, rust, algae and other debris.

Disconnected Drain Line

When Air Conditioner systems are improperly installed drain pipe fittings may not be secure. Over time, they can loosen, causing the drain pipe to disconnect from the AC unit and allowing the condensate to drain through the ceiling or onto the floor. As with a clogged drain line, the location of the leak will depend on whether the primary or secondary drain pipe is the one affected and whether your central AC system is located in the attic or in your house.

Condensate Pump Problems

A malfunctioning or dirty condensate pump can also cause water leakage from your central air conditioning system, flooding your attic or basement. Due to the continual presence of water, mold and mildew can grow inside the unit, causing it to clog.

Other Potential Causes of AC Water Leakage

Water leaks can also be caused by the following issues:

  1. Clogged air filter
  2. Low refrigerant
  3. Cracked condensate drain pan
  4. Condensate buildup in un-insulated ductwork

    What are the Risks Involved not repairing leaky air conditioners?

Many people dismiss this problem, not knowing why air conditioner repair is necessary. Don’t be one of them. These are the results of a leaky machine:

  • A leaky air conditioner costs you money. You’re paying for energy that isn’t translating into a cooler home.
  • Failing to take care of the problem will increase the wear and tear on the machine, potentially causing lasting damage and/or a breakdown of the system.
  • Ignoring the problem until it’s too late means having to buy a completely new system. You can avoid buying a new air conditioner if you pay attention to early warning signs.
