As the temperatures rise and we start relying on our HVAC systems to keep us cool, the last thing we want to deal with is a leak. However, HVAC system leaks are a prevalent problem encountered by homeowners. Not only can they decrease the efficiency of your system, but they can also cause damage to your home and ultimately drain your wallet. 

Let’s learn more about HVAC leaks as you continue reading!

Types of HVAC Leaks

Before we get into the sources of leaks, let’s talk about the different types of HVAC leaks. There are two main types – refrigerant leaks and water leaks.

  • Refrigerant Leaks: These occur when there is a leak in the refrigerant line, causing the refrigerant to escape. This can lead to a decrease in cooling efficiency and potential damage to your system.
  • Water Leaks: These occur when there is a leak in the condensate drain line, which carries away excess water from your system, leading to mold growth and water damage if left untreated.

Now that we have a better understanding of the types of leaks, let’s explore the common sources of these leaks.

Common HVAC Leak Sources

Damaged or Clogged Condensate Drain Line

As mentioned earlier, the condensate drain line is responsible for carrying away excess water from your system. If the line sustains damage or becomes obstructed by debris, it has the potential to result in water backing up and leaking from your system.

Corroded Coils

The HVAC system’s coils are responsible for heat transfer and air cooling. However, long-term exposure to moisture and environmental elements can cause corrosion, which results in small holes and refrigerant leaks in the coils.

Loose or Damaged Refrigerant Lines

The refrigerant lines are responsible for carrying the refrigerant throughout your system. If these lines become loose or damaged, it can cause a leak in the refrigerant and impact the performance of your system.

Faulty Seals

There are various seals in your HVAC system that help to keep everything in place. Over time, these seals can become worn or damaged, causing leaks to occur.

Improper Installation

Improper installation of your HVAC system may result in different problems, such as leaks. Leaks can occur due to poorly connected components or incorrect placement.

Now that we know where these leaks can come from, let’s look at the signs that may indicate you have a leak in your system.

Signs of Heating and Air Leaks

Your HVAC system is designed to run efficiently and quietly, so any unusual sounds or behaviors should be investigated. Here are some signs that may indicate a leak in your system

Water Pools Around Your System

If water accumulates around the indoor unit or close to the condensate drain line, it may indicate a potential leak.

Unusual Sounds

Hissing or bubbling sounds emanating from your HVAC system might be a sign of a refrigerant leakage.

Increase in Energy Bills

Leaks in your HVAC system can cause it to work harder and use more energy, leading to an increase in your energy bills.

Warm Air Coming from Vents

If warm air is coming out of your vents instead of cool air, this could indicate a refrigerant leak.

Now that we’ve identified some common sources and signs of HVAC leaks, let’s talk about the methods used for detecting these leaks.

Methods Used for Leak Detection

At Elite Air & Heat, we employ various methods for detecting HVAC leaks. These include:

Visual Inspection

Our experienced technicians will visually inspect all components of your HVAC system, including the seals and connections, to look for any signs of leaks.

Pressure Testing

We use pressure testing equipment to check the pressure levels in your HVAC system, which can indicate if there is a leak present.

Dye Testing

This method involves adding a fluorescent dye into your HVAC system to help us locate the source of a leak under UV light.

Thermal Imaging

Using thermal imaging technology, we can detect temperature changes that may be caused by leaks in your system.

Once we have identified a leak in your HVAC system, it’s important to repair it promptly to avoid further damage and potential safety hazards.

Repairing HVAC Leaks

The method of repairing an HVAC leak will depend on the type and severity of the leak. Our technicians are trained to handle all types of leaks and use the appropriate methods for repair, which may include:

Sealing or Patching

In some cases, a small leak can be sealed or patched with special materials to prevent further leakage.

Replacing Parts

If a component of your HVAC system is the source of the leak, we may need to replace that part entirely.


For older systems, we may recommend retrofitting or upgrading certain parts to prevent future leaks.

It’s important to note that attempting to repair an HVAC leak on your own can be dangerous and may cause further damage to your system. It’s always best to leave leak repairs to trained professionals.
