Most homeowners have limited knowledge of their HVAC systems and how they operate. Though you need an HVAC contractor to perform necessary repairs, you should still be able to determine if your equipment is having issues or when to schedule routine maintenance. Here’s what you should know about your unit.

What Do You Need to Know About Your HVAC System?

1. How Old It Is

Most HVAC systems have a life span of about 10 to 15 years with proper upkeep. Units that haven’t had regular maintenance are likely to experience issues even sooner and may require replacement equipment. When you know the age of your system, you can gauge its remaining service life and plan ahead.

2. When to Replace the Air Filter

Air filters ensure your heating and cooling equipment functions correctly. They also maintain the air quality in your home, which prevents mitigates with allergies or other respiratory problems. Filters must be changed according to schedule, which varies based on factors like the size of your equipment, whether you have pets, and how often you use the system. In general, replace filters every two to three months—monthly if you have animals in the house.

3. Which Noises Are Abnormal

While all HVAC systems make some noise when operating, banging or squealing is not typical. Odd sounds can indicate that components are loose, broken, or grinding together. Don’t ignore them for too long; call an HVAC contractor before the system breaks down completely.

4. How the System Operates

Some HVAC systems have central air ducts that carry hot and cool air around the home, while others use refrigeration lines and in-room units for zoned climate control. When generating heat, some systems heat water; others use hot air to turn water into steam. There are also heat pumps, which don’t actually generate heat but instead move air around the home to control the temperature. Basic operational information helps you detect any problems before they get worse.
