Refrigerant leaks and what to do about them

Is your HVAC system making weird sounds and not cooling your house very well this summer? If so, chances are you have a refrigerant leak.

Refrigerant is an essential part of your HVAC system. It is the liquid/gas that actually turns your home’s warm air into cold air. When your HVAC system is low on refrigerant, your AC can’t cool your home efficiently and you risk damaging your air conditioner. We’ll tell you the cause of refrigerant leaks, how to get it fixed correctly and how to keep it from happening again.

What causes a refrigerant leak?

Whenever your system was installed, the proper amount of refrigerant was added. If working and sealed correctly, this refrigerant should stay inside your AC’s coils and constantly recirculate.

However, sometimes holes and cracks develop in the coils, which causes the refrigerant to leak. As the refrigerant level drops, your space gets harder to cool, causing the air to become warmer. Usually these leaks happen due to the age of your HVAC system because the metal coils wear over time. A leak could also be due to corrosion on the coils, like grime and pollutants, due to neglected maintenance.

How to properly fix your refrigerant leak ?

Some unscrupulous HVAC companies may recommend that you just add more refrigerant to get you through the summer, but this is a very shortsighted solution. Doing this will damage your system and eventually leave you paying just as much as you would to properly fix the leak.

There are two options for fixing your refrigerant leak the correct way:

1. Find and repair the hole(s). Quality HVAC service providers have equipment that quickly detects leaks and repair them.

2. Replace the AC coil. If your system is old or in poor condition, it might be time to replace the entire coil. This option is the most expensive, but when your system is properly repaired you’ll experience better performance, lower energy bills and no more recurring leaks.

How to avoid refrigerant leaks in the future ?

In most cases, refrigerant leaks are preventable with regular system maintenance. At least once or twice a year, invest in maintenance to keep your HVAC system in optimal condition.

The Importance of Maintaining Cooling Towers

WG Speeks services and installs all types of heating/cooling needs for commercial or industrial buildings, and this includes cooling towers. Cooling towers allow the majority of the water being used to be recycled, eliminating an enormous amount of water wastage.

They are also the key to maximizing chiller efficiency and ensuring longer overall system life. But just like other HVAC units, they require proper maintenance to ensure they’re running at peak efficiency.

=>> Here are few cooling tower maintenance tips to keep in mind:

1. Inspect your motors

In many water-based cooling systems, cooling tower fan motors draw the most electricity out of any component. The standard motors operate at only one or two speeds, which can leave them using too much electricity as the overall system load decreases.

It’s important to have your motors inspected by a professional over time. You may opt to install a premium motor, because they can reduce electricity use by 8%. These high-efficiency motors are more expensive than the standard motors, but in a large commercial building with cooling needs, savings will add up quickly.

2. Manage Water Levels

Cooling towers must have the correct water level to perform that their optimal efficiency. It’s also important to note that overfilling can lead to roof damage. With daily inspection, it is easy to keep this in check. Having a meter installed to monitor water levels can simplify this process.

 

3. Ensure Contamination Compliance

There are special inspection and decontamination rules for cooling towers. These rules are mainly in place to prevent outbreaks of the deadly legionella bacteria, which causes pneumonia like symptoms. Because cooling towers are outside, they are vulnerable to contaminants like leaves, dirt and soot. This also poses a health risk. Make sure your cooling tower is tested regularly for these issues.
