May 23, 2024 3 mins to read

Heating, Ventilation, and Air Conditioning (HVAC) systems are the unsung heroes of home comfort, silently working in the background to ensure your living space remains a sanctuary regardless of the weather outside. However, like all heroes, your HVAC system requires a little support to continue performing at its best. Whether you’re a new homeowner or a seasoned DIY enthusiast, understanding the basics of your HVAC system and learning a few maintenance tips can save you money, improve your home’s energy efficiency, and extend the system’s lifespan.

The Basics of HVAC Systems

Before we dive into maintenance tips, let’s quickly cover what an HVAC system comprises. At its core, an HVAC system controls the temperature and air quality in your home. This includes Broan-NuTone:

  • Heating: This is typically done through a furnace or boiler that heats air or water, distributing warmth throughout your home.
  • Ventilation: This process exchanges indoor and outdoor air, removing contaminants, moisture, and odors from inside your home.
  • Air Conditioning: Air conditioners remove heat and humidity from your home, keeping you cool during warmer months.

Understanding these components is the first step in maintaining a comfortable home environment.

Maintenance Tips for Your HVAC System

1. Regularly Replace or Clean Air Filters

One of the simplest yet most effective ways to maintain your HVAC system is by regularly checking and replacing the air filters. Dirty filters restrict airflow, reducing efficiency and putting extra strain on your system. Depending on your filter type, you should replace or clean it every 30-90 days.

2. Keep Your Vents Unblocked

Furniture, curtains, and rugs can block vents, preventing air from circulating properly. Ensure all supply and return air vents are clear of obstructions to maintain consistent temperatures throughout your home.

3. Schedule Annual Professional Maintenance

While there are many aspects of HVAC maintenance you can do yourself, a professional technician should check your system annually. They can perform a more thorough inspection, identifying and fixing potential issues before they escalate.

4. Seal and Insulate Ductwork

Leaks and poor insulation in ductwork can significantly reduce your system’s efficiency. Inspecting your ducts for leaks and ensuring they are well-insulated can improve your HVAC system’s performance and reduce energy costs.

5. Monitor Thermostat Settings

Investing in a programmable thermostat can significantly enhance your HVAC system’s efficiency by adjusting the temperature based on your schedule. Setting your thermostat to a lower temperature in winter and a higher temperature in summer when you’re not home can lead to substantial savings.

6. Keep Outdoor Units Clear

If your HVAC system includes an outdoor unit, keep it free from debris, leaves, and plants. Ensure there’s at least a 2-foot clearance around the unit to allow for adequate airflow.

7. Listen for Unusual Noises

Pay attention to your HVAC system’s operation. If you notice unusual noises, such as banging, grinding, or whistling, it may indicate a problem that needs professional attention.


Your HVAC system plays a crucial role in maintaining a comfortable and healthy home environment. By following these essential maintenance tips, you can ensure it continues to operate efficiently and effectively for years to come. Remember, regular upkeep not only extends the lifespan of your HVAC system but also improves your home’s air quality and reduces energy costs. Stay proactive about your system’s maintenance, and don’t hesitate to consult with a professional for annual check-ups or when issues arise.
