Having a functional HVAC system is an important part of home comfort, especially during Charlotte, North Carolina’s warm summers. Knowing the most common signs that your system needs repairs can help you get your HVAC unit running properly in a timely manner and prevent major breakdowns. Here are three of the most common signs that something is going wrong with your HVAC unit.

Low Air Flow

Low or no airflow from your vents indicates issues within your HVAC system. Possible causes include dirty coils, a poor connection with the thermostat, or compression failure. First, check to see if your filter is dirty. This is one of the most common reasons for low airflow and is an easy fix. However, anything more serious should be tackled by a NATE-certified technician. Issues like compression failure need to be addressed as soon as possible. Otherwise, they can lead to massive system failures, and you may need to purchase a replacement for your unit.

Noise

Your HVAC system should run pretty quietly. The noise of air coming from the ducts is normal, and so is a humming sound when the system starts up. However, if you start to hear things like a metallic whine or thumping, there may be an issue within your system. This can be caused by factors like debris in the outside portion or parts wearing down. These can often be quickly diagnosed by a professional and fixed, provided they are caught early enough.

Humidity

A major part of your HVAC system’s job is to remove humidity from the air and keep your home’s moisture levels balanced for optimum comfort. While you may have a slight increase in humidity during the damp summer months, it should barely be noticeable. If your home has been feeling damp even when you use ventilation systems, you should contact a professional. There are a variety of reasons for this issue, and most can be fixed within a few hours.
