Unpredictable weather can be a real test for your HVAC system, and when it falters, comfort takes a hit. But how do you know what problem your HVAC system is struggling with?

Luckily, we’ve got the information you need.

Let’s go through the most common HVAC problems and how to fix them.

1. Dirty Filters

Over time, air filters accumulate dust, dirt, and other particles, reducing their effectiveness.

When filters become dirty, they impede airflow, causing the HVAC system to work harder to keep the right temperature. This higher workload can result in higher energy consumption and utility bills.

To address dirty filter issues, regular maintenance is crucial. Homeowners should check and replace air filters according to the manufacturer’s recommendations, typically every one to three months. Some HVAC filters are reusable and can be cleaned, while others need to be replaced. 

Other things in your HVAC system might need to be cleaned, too. Don’t neglect getting your ducts cleaned, if necessary.

2. Water Leaks

You also need to watch out for water leaks. 

These leaks can originate from various components, such as the condensate drain line, evaporator coil, or even the air handler. When left unattended, HVAC water leaks can lead to structural damage, mold growth, and compromised system performance.

Homeowners should schedule routine inspections by HVAC professionals to clean and clear the drain line, preventing clogs and potential leaks.

Installing a condensate drain pan with a float switch can serve as a secondary measure to detect and alert homeowners to potential leaks before they cause significant damage.

3. Blown Fuse

Fuses are safety devices designed to protect electrical circuits from overcurrent, and when they blow, it indicates a problem within the system.

One common cause of blown fuses in HVAC systems is electrical overloading. This can occur when there is a sudden surge in electrical current, often due to a malfunctioning component or a short circuit.

To address blown fuse issues, homeowners should first identify and rectify the underlying cause. This may involve troubleshooting the specific components connected to the blown fuse, checking for loose wiring, or inspecting the electrical connections.

It is crucial to turn off the power to the HVAC system before attempting any inspection or repair to ensure safety.

4. Malfunctioning Thermostat

The thermostat serves as the control center, regulating the temperature and enabling users to set their desired heating or cooling preferences. When the thermostat malfunctions, it can lead to air quality issues, energy inefficiency, and potential system malfunctions.

To address thermostat inaccuracies, homeowners can recalibrate the device or relocate it to a more suitable position.

Regular cleaning of the thermostat’s sensors is also essential to ensure accurate temperature readings. If recalibration and cleaning do not resolve the issue, it may be necessary to replace the thermostat.
