7 Top HVAC Maintenance Tips: Keep Your System Running Smoothly

Regular maintenance is essential if you want your home’s heating and cooling system to run smoothly and efficiently. Southern Air Mechanical recommends the following HVAC maintenance tips to extend the lifespan of your system and help you save money on energy bills. 

1. Change your air filters

We’ve said it before, and we’ll say it again. The most simple yet crucial of all our HVAC maintenance tips is to change your air filters regularly. Dirty and clogged filters restrict airflow, making your system work harder. Reduced efficiency shortens the system’s lifespan and increases your energy bills. Check your filters every 1-3 months and replace them when they appear dirty or clogged. This small task can significantly improve the efficiency of your HVAC system.

2. Clean the vents and ducts

Over time, dust and debris can accumulate in your vents and ducts, obstructing the airflow. Obstructions lead to reduced efficiency and poor indoor air quality. To keep your HVAC system running smoothly, schedule periodic duct cleaning. You can also vacuum the vents and registers to remove visible dust or debris.

3. Keep the outdoor unit clear

If you have a central air conditioning system, ensure the outdoor unit (condenser) is free from obstructions. Trim any bushes or plants that might block airflow, and regularly remove debris like leaves or twigs. A clear outdoor unit allows for better heat exchange, improving the efficiency of your air conditioner.

4. Check and calibrate your thermostat

An essential piece of a functioning HVAC system is your thermostat. A correctly calibrated thermostat provides accurate temperature readings. Use a separate thermometer to check its accuracy and adjust it if necessary. Additionally, consider upgrading to a programmable or smart thermostat, which can help you optimize your system’s performance and save on energy costs.

5. Seal leaks in the ductwork

A leak anywhere in your ductwork can significantly impact your energy use. Leaks allow air to escape into unconditioned spaces like your attic. Inspect your ductwork for visible leaks and seal them with duct tape or mastic sealant. Insulated and sealed ducts can improve the efficiency of your HVAC system and reduce energy consumption.

6. Monitor refrigerant levels

For air conditioning systems, it’s essential to monitor refrigerant levels. If you notice your home isn’t cooling as it should or hear hissing sounds coming from your outdoor unit, it could indicate a refrigerant leak. In such cases, contact a technician to assess and repair the issue.

7. Balance airflow

Uneven airflow can result in some rooms being too hot or too cold. To address this, you can adjust the dampers in your ductwork to balance the airflow throughout your home. Adjusting airflow helps ensure that each room receives the right amount of conditioned air, improving comfort and system efficiency.
