What are some common HVAC issues and how can I fix them myself?

1. Dirty air filter: A dirty air filter can cause your HVAC system to work harder and decrease airflow. You can solve this by checking and replacing the filter regularly.

2. Thermostat problems: If your HVAC system isn’t turning on or off at the correct time, or the temperature isn’t accurate, it could be a problem with the thermostat. Check the wiring or batteries in your thermostat and replace them if necessary.

3. Clogged drain line: A clogged drain line can cause water to leak or back up in your HVAC system. You can solve this by turning off the system and clearing the clog with a wet/dry vacuum.

4. Refrigerant leak: A refrigerant leak can cause your HVAC system to stop blowing cold air. This is a more advanced issue that should be addressed by a professional.

5. Loud or unusual noises: If you hear unusual noises coming from your HVAC system, such as banging or rattling, it could be a sign of a mechanical issue. Turn off the system and call a professional to diagnose and fix the issue.
