Is Your Home's HVAC at Risk for Low Refrigerant Levels?

Is your HVAC system not cooling like it used to? Here's how to tell if low refrigerant levels are the issue and what to do about it.As the weather starts to cool down, you may not be thinking about your home’s heating, ventilation and air conditioning (HVAC) system. But if your HVAC system uses refrigerant, now is the time to have it checked before turning on the heat for the season. Low refrigerant levels are one of the most common issues with HVAC systems, and can lead to a host of problems, from decreased efficiency to complete system failure.

As the weather outside gets colder, you may not be giving much thought to your HVAC system. But did you know that low refrigerant levels can actually affect your system’s performance in winter? Here’s what you need to know about how low refrigerant levels can impact your HVAC system and what you can do to keep your system running smoothly all year long.

How Can Low Refrigerant Levels Affect Your HVAC System?

If your home’s HVAC system is low on refrigerant, it won’t be able to effectively cool your home. This can lead to a number of problems, including increased energy bills, as the system will have to work harder to cool your home. Low refrigerant levels can also cause damage to the compressor, which is an expensive repair. To avoid these problems, it’s important to have your HVAC system serviced regularly and to check the refrigerant levels periodically.

One of the most important things your HVAC system needs to run properly is adequate refrigerant levels. Refrigerant is what helps cool air as it passes through your system. If there isn’t enough refrigerant, the air won’t be cooled properly and your system will have to work harder to maintain a comfortable temperature inside your home. This can lead to increased energy bills and premature wear and tear on your HVAC system.

The Signs of Low Refrigerant Levels: What to Look For

If your home’s cooling system uses refrigerant, you may eventually have to recharge the system. Recharging the system is a relatively easy process, but it’s important to know when it needs to be done. Low refrigerant levels can cause a number of problems, so it’s important to be aware of the signs that indicate a need for recharging.

One sign that your system may be low on refrigerant is ice buildup on the evaporator coils. The coils are located in the indoor unit of your air conditioner or heat pump. If there is ice on the coils, it means that the coils are not absorbing heat properly. This can lead to decreased efficiency and higher utility bills.

Another sign of low refrigerant levels is hissing or bubbling noises coming from the outdoor unit of your air conditioner or heat pump.

The Consequences of Low Refrigerant Levels: What Can Happen if You Don't Address the Issue?

If your home’s refrigerant levels are low, it’s important to take action to address the issue. Low refrigerant levels can cause a number of problems for your home’s heating, ventilation, and air conditioning (HVAC) system, including:

Reduced efficiency: Your HVAC system has to work harder to maintain the desired temperature in your home when refrigerant levels are low. This can lead to increased energy bills and wear and tear on your system.

Damage to components: Low refrigerant levels can cause damage to the compressor and other vital components of your HVAC system. This damage can be expensive to repair or replace.

System failure: In extreme cases, low refrigerant levels can cause your entire HVAC system to fail.

How to Check Your HVAC's Refrigerant Levels: A Step-by-Step Guide

If your HVAC unit isn't cooling your home like it should, there's a chance that the refrigerant levels are low. Here's a step-by-step guide on how to check your HVAC unit's refrigerant levels: 

1. Turn off the power to your HVAC unit.

2. Locate the access panel on the side of the unit.

3. Remove the panel and locate the Schrader valve.

4. Attach a gauge to the valve and open it up.

5. If the reading on the gauge is below 30 psi, then your refrigerant levels are low and you'll need to call a professional to add more.

How to Recharge Your HVAC's Refrigerant: What You Need to Know

If your air conditioning unit requires refrigerant, you'll need to get an AC professional. The Environmental Protection Agency stipulates that only qualifying professionals can recharge your HVAC system. Do not use recharging tools unless you have professional experience with it. The refrigerant can be hazardous to you and the environment.

The Importance of Keeping Your HVAC's Refrigerant Levels Topped Up

In conclusion, it is important to keep your HVAC's refrigerant levels topped up in order to maintain optimal performance and efficiency. A lack of refrigerant can cause your system to overwork and break down, so it is important to check your levels regularly and top them up when necessary. By doing so, you can extend the life of your HVAC system and keep it running smoothly for years to come.

How can you tell if you have low refrigerant levels?

One way to tell if your refrigerant levels are low is if your air conditioner is running constantly but not keeping your home as cool as it should. Another sign is if the coils on your AC unit are frozen.

If you think your refrigerant levels might be low, the best thing to do is call a professional for help. They can check the level and recharge your system if necessary.
