Some HVAC maintenance tasks are simple and safe enough for most homeowners to do themselves. These tasks can help keep your system running smoothly between professional visits.
1. Replace Air Filters
- Why It’s Important: Dirty filters restrict airflow, reduce efficiency, and strain your system.
- How to Do It: Check your filter every 1-3 months and replace it if it’s dirty. Make sure to use the right size for your system.
2. Clean Around Outdoor Units
- Why It’s Important: Debris like leaves, grass, and dirt can block airflow and reduce efficiency.
- How to Do It: Trim vegetation back at least two feet from the unit and gently rinse it with a garden hose to remove buildup.
3. Inspect and Clean Vents
- Why It’s Important: Blocked vents reduce airflow and strain your system.
- How to Do It: Vacuum dust and debris from vents and make sure furniture isn’t obstructing them.
4. Monitor System Performance
- Why It’s Important: Spotting unusual noises, smells, or performance changes early can prevent bigger problems.
- How to Do It: Pay attention to how your system operates and make note of anything unusual.
When to Call a Professional
While some tasks are safe to DIY, others require the skills, tools, and experience of a licensed HVAC professional. Attempting these tasks yourself can be dangerous and may void your system’s warranty.
1. Annual System Tune-Up
- Why It’s Important: Professionals perform a thorough inspection, clean components, and address potential issues before they become major problems.
2. Refrigerant Handling
- Why It’s Important: Refrigerants are chemicals regulated by the EPA. Handling them without proper certification is illegal and dangerous.
3. Electrical Repairs
- Why It’s Important: HVAC systems have complex electrical components that require specialized knowledge to repair safely.
4. Diagnosing and Fixing System Issues
- Why It’s Important: If your system isn’t heating, cooling, or running efficiently, a professional can pinpoint the issue quickly and correctly.
