DIY HVAC Maintenance: What You Can Do & When to Call a Pro
Regular HVAC maintenance is essential for keeping your system running efficiently, preventing costly breakdowns, and extending its lifespan. While some maintenance tasks can be handled on your own, others require the expertise of a professional.
So, what can you do yourself, and when is it time to call the pros? Let’s break it down!
DIY HVAC Maintenance Tasks
These simple maintenance steps can help keep your system in top shape and prevent common issues:
1. Change Your Air Filters Regularly
? How Often? Every 1-3 months, depending on pet dander, allergies, and usage.
? Why? Dirty filters restrict airflow, reducing efficiency and indoor air quality.
? How? Locate the filter slot, remove the old filter, and insert a new one with the airflow arrows pointing in the correct direction.
2. Keep Vents & Registers Clean
? How Often? Once a month.
? Why? Blocked vents make your system work harder, increasing energy costs.
? How? Use a vacuum to remove dust and debris from vents and make sure furniture isn’t blocking airflow.
3. Check & Clean the Outdoor Unit
? How Often? At least twice a year (spring and fall).
? Why? Leaves, dirt, and debris can block airflow and reduce efficiency.
? How? Turn off the power, remove any debris around the unit, and gently rinse the coils with a garden hose (never use a pressure washer).
4. Adjust Your Thermostat for the Season
? Why? Optimizing your thermostat settings can save you money on energy bills.
? Recommended Settings:
- Summer: Set to 78°F when home, 85°F when away.
- Winter: Set to 68°F when home, 60°F when away.
5. Inspect & Clean Drain Lines
? How Often? Every few months.
? Why? Clogged drain lines can cause water leaks and mold growth.
? How? Pour a cup of vinegar down the drain line to help clear buildup.
When to Call a Professional
Some HVAC issues require a trained technician. Here’s when you should leave it to the pros:
1. Strange Noises or Odors
? Signs: Loud banging, screeching, rattling, or a burning smell.
? Possible Issues: Loose parts, electrical problems, or motor failure.
2. Weak Airflow or No Cooling/Heating
? Signs: Some rooms feel warmer or cooler than others, or the system isn’t reaching the set temperature.
? Possible Issues: Refrigerant leaks, ductwork blockages, or compressor failure.
3. High Energy Bills Without Explanation
? Signs: Sudden spikes in energy costs without changing usage habits.
? Possible Issues: Dirty coils, duct leaks, or an aging system struggling to keep up.
4. Frequent Cycling On & Off
? Signs: The system turns on and off too frequently.
? Possible Issues: A faulty thermostat, dirty filters, or an issue with the compressor.
5. Ice Buildup on Your AC Unit
? Signs: Ice forming on the indoor or outdoor coils.
? Possible Issues: Low refrigerant, poor airflow, or a dirty evaporator coil.
