A heating and cooling system needs proper care and maintenance to operate efficiently and prolong its natural life span. If you’re absentminded or cut certain corners, you’ll likely experience untimely breakdowns with your HVAC equipment, which can leave you with uncomfortable indoor temperatures, a hefty repair bill, and even a system that needs replacing before its time. To get the most comfort and value out of your investment, make sure you don’t do any of the following.

3 HVAC Maintenance Mistakes to Avoid

1. Adjusting Temperatures Too Frequently

Your system works hard to give you the comfortable temperature you desire. However, when you frequently adjust the temperature setting from a higher to a lower setting and vice versa, you put stress on the unit’s internal components, which may ultimately lead to malfunctions.

As such, it’s best to select your ideal temperature setting and stick with it. Alter your indoor temperatures without tinkering with the thermostat by opening or closing your windows and wearing more comfortable clothes indoors.

2. Forgetting to Replace the Air Filter

HVACThe performance of your heating or cooling equipment is affected when your air filter is dirty. The filter traps dust, pollen, and other harmful contaminants and prevents them from circulating indoors, improving your indoor air quality. 

In addition, a buildup of these particles can clog the filters and suppress airflow through the HVAC system, forcing it to work harder than normal, which may shorten its working life. Avoid this problem by replacing—or cleaning, if it’s a reusable model—your filter at least four times annually or whenever necessary.

3. Neglecting Scheduled Maintenance

Check the owner manuals and take note of when you should have your furnace or AC compressor inspected. Ignoring preventive maintenance means you’ll continue to operate your equipment even if there’s a potential problem.

If these issues aren’t resolved quickly, your unit may break down, compromising your comfort. If this happens often enough, you may be looking at a replacement system. HVAC technicians are knowledgeable not only in changing air filters and repairing damaged parts but also determining possible complications to your unit.
