A functioning heating and cooling system is essential for any household in the country. Your unit operates daily to keep you as comfortable as possible. However, in time, your HVAC system gets worn down.

Common Problems of Heating and Cooling Systems

With constant usage, you might notice some issues with your unit, especially if it hasn’t been maintained properly. By keeping an eye on your HVAC system, you are more likely to spot problems that can otherwise escalate if left unnoticed. Some of the issues you need to be mindful of include the following:

• Broken Thermostats

A thermostat is responsible for regulating the temperature in your home. With this device, you can simply set your desired warmth or coolness and relax.

But issues with the thermostat can prevent you from feeling comfortable. If your unit is no longer heating up or cooling down once the settings have changed, then there might be an underlying problem. Once you notice that something is amiss, you should check if something is wrong with the thermostat.

Before consulting a professional regarding thermostat problems, it is best to read your unit’s manual and go through the operating instructions. Doing so can help you figure out the best way to troubleshoot this device, especially if it’s an older analog or mechanical model. Changing the batteries might also do the trick. If you cannot find the answer during your perusal, it’s time to get in touch with a professional to determine the issue and know how to solve it.

• Unusual Sounds Coming From the Furnace

This problem can be tricky since a furnace normally makes noise whenever it’s in use. But certain sounds can actually indicate an underlying mechanical problem. If you notice a whining or squealing noise, there might be an issue with the blower or inducer motor. Unusual sounds can also indicate that the burners need to be cleaned.

To keep your furnace from breaking down, it is best to consult an HVAC specialist as soon as you notice these odd signs. They will be able to thoroughly inspect your unit and resolve the issue promptly.

• Dirty Filters

This is one of the commonly occurring problems with HVAC systems. With constant usage, all the dust, dirt, dander, and debris that have been caught by this component will eventually accumulate. The buildup inhibits airflow, which forces your units to work harder. This accumulation can speed up the mechanical and electrical wear and tear of your HVAC system.

The simplest way to address this issue is by cleaning your filter regularly. If the one you currently have is not reusable, you can simply replace it. A rule of thumb is to change filters at least once per season.

• Clogged Drains

Impurities that have accumulated in an HVAC unit’s drainage system can cause blockage. Unless the clog is cleared immediately, moisture will flow to areas of the machine that must remain dry, resulting in more serious problems.

To resolve the issue, remove the drain pipe from the outer part of the unit and clear it using a cleaning product of your choice. If you are having difficulty doing this on your own, hire a specialist to help you out.

• Refrigerant Leaks

The air produced by an HVAC unit is cooled down using a liquid called refrigerant. It plays a significant role in lowering the temperature of any room. Before the air that passes through the HVAC system is released, it is cooled by the refrigerant that goes through the coils. Considering its importance, it is essential to address any issues with it as soon as you notice signs of problems.

Damage caused by constant vibration in the unit or the weakening of its connections can lead to refrigerant leaks. If you have this problem, you will likely notice leakage and foul odor coming from the vents. The best way to address the problem is by turning off the unit and calling a professional immediately.

Regular DIY maintenance can help keep your unit in good condition, but having a professional service the equipment allows it to last longer and perform better. Choosing the right heating and cooling specialist to inspect your system will enable you to know if there’s anything wrong and what can be done to solve it.
