How to Maintain Your HVAC System for Year-Round Comfort

Your HVAC system works hard all year long, keeping your home warm in the winter and cool in the summer. Regular maintenance not only extends its lifespan but also improves efficiency and lowers energy costs. Here’s what you need to do to keep your HVAC system in top shape.

1. Change Your Air Filters Regularly

A clogged air filter makes your HVAC system work harder, reducing efficiency and air quality. Change or clean your filter every one to three months, especially during peak heating and cooling seasons.

2. Schedule Professional Maintenance Twice a Year

Having an HVAC technician inspect and service your system in spring and fall ensures it's ready for the upcoming season. They’ll check refrigerant levels, clean coils, and ensure everything is working correctly.

3. Keep Your Outdoor Unit Clear

If you have a central AC unit or heat pump, keep the area around it free of debris, leaves, and overgrown vegetation. This helps maintain proper airflow and prevents the system from overheating.

4. Check and Clean Your Vents

Blocked vents force your HVAC system to work harder. Make sure furniture, rugs, or curtains aren’t obstructing vents, and vacuum them regularly to remove dust buildup.

5. Program Your Thermostat for Efficiency

A smart thermostat can optimize your home’s temperature when you’re away, saving money on energy bills. In the summer, set your thermostat to 78°F when home and higher when away. In the winter, 68°F is ideal for energy savings.

6. Inspect Your Ductwork for Leaks

Leaky or dirty ductwork can lead to higher energy bills and poor air quality. If you notice inconsistent temperatures or excessive dust, it may be time for duct cleaning or sealing.

7. Listen for Unusual Noises

Banging, rattling, or squealing noises could indicate problems with your HVAC system, such as loose parts, a failing motor, or a clogged blower. Don’t ignore unusual sounds—have a professional inspect them early to prevent costly repairs.

8. Don’t Ignore Unusual Smells

A musty smell could mean mold growth in the ducts, while a burning odor might indicate an electrical issue. If you smell gas, turn off your system immediately and call a professional.

Shawn's Final Thoughts

Regular HVAC maintenance helps reduce repair costs, improve energy efficiency, and keep your home comfortable year-round. A little upkeep goes a long way in preventing major issues down the road.
