BLOG Troubleshooting Your HVAC System: Expert Tips from Storey’s Services Aug 26, 2025

Is your HVAC system not performing up to par? Before you call in the professionals, there are a few troubleshooting steps you can take on your own. At Storey’s Services, our goal is to equip you with practical tips to help you efficiently manage your HVAC system. Whether you're dealing with a lack of heating or cooling, unusual noises, or system inefficiencies, these expert guidelines may help you address some common issues.

First, ensure your HVAC system’s thermostat is set correctly. Incorrect thermostat settings can often be the simplest cause of HVAC problems. Double-check that it’s on the proper mode—'Heat' during the winter months and 'Cool' in the summertime. Furthermore, consider upgrading to a programmable thermostat, allowing for more precise temperature control and energy savings.

Next, inspect the air filters. Clogged or dirty filters restrict airflow, causing your HVAC system to work harder than necessary and reducing its lifespan. Regularly replacing the filters can significantly improve efficiency and indoor air quality. Ideally, check them every month, especially during peak usage times, and replace them every three months, or more frequently if necessary.

Don’t forget the ducts. Airflow issues may also stem from your ductwork. Leaks or blockages can substantially diminish your system’s effectiveness. Look for visible signs of damage along the ducts. In many cases, sealing leaks or clearing blockages can restore optimal function. However, if you notice extensive damage, it may be wise to have a professional from Storey’s Services inspect and repair your ducts.

Additionally, inspect the outdoor unit. Debris such as leaves, dirt, and twigs can obstruct the external components of your HVAC system. Make it a habit to clean the area around your outdoor unit regularly. Ensure that it has at least two feet of clearance on all sides to allow proper ventilation. This simple step can enhance efficiency significantly.

Unusual noises originating from your HVAC system are often indicators of a problem. Rattling sounds may hint at loose parts, while hissing could indicate a refrigerant leak. Although some noise is customary, sudden shifts in the usual noise level require attention. If you’re unable to identify the noise, consult with an HVAC professional.

Moreover, verify your home's insulation. Poor insulation can cause your HVAC system to work overtime, driving up your energy bills and wearing down components. Check windows, doors, and attic spaces to ensure they are adequately sealed.

Finally, regular preventative maintenance is key to extending the life of your HVAC system. Scheduling seasonal inspections with Storey’s Services can uncover potential issues before they escalate, ensuring a reliable and efficient system year-round.

While these DIY troubleshooting tips can address many common issues, nothing replaces professional care. At Storey’s Services, our expertise ensures your HVAC system operates at peak performance.
