How do I reset my HVAC system?

Sometimes, a simple reset can resolve minor HVAC issues. Here's how to reset your HVAC system:
  1. Turn off the system: Switch off your HVAC system at the thermostat.

How do I choose the right HVAC filter?

When choosing an HVAC filter, consider:
  • MERV Rating: The Minimum Efficiency Reporting Value (MERV) indicates the filter's ability to trap particles. Higher MERV ratings mean better filtration.
