FAQs

Does your HVAC maintenance service in Gallatin address common local issues like clogged drains?

Yes, absolutely. Our standard maintenance service for Gallatin homes includes checking and clearing the condensate drain line, which is a frequent cause of system shutdowns and water damage in our humid climate. We also inspect heat pump reversing valves and other components prone to wear from our seasonal temperature swings to help prevent unexpected breakdowns.

What is included with a new HVAC system installation from O2 Defense?

Every new HVAC unit we install, regardless of the model or price range, comes standard with integrated antiviral air purification technology. This system is designed to work within your central heating and cooling to help reduce airborne contaminants. We handle the entire installation process professionally, ensuring your new system is set up correctly for optimal efficiency and air quality from day one.

I can't afford a full system replacement. Do you offer air purification for my existing HVAC?

Yes, we do. We specialize in making air purification accessible.
