- Air Filters: Essential for maintaining indoor air quality by trapping dust, allergens, and other particles.
How HVAC Works to Maintain Comfort
The heart of an HVAC system is its ability to effectively heat or cool an environment. When the temperature in a space rises above the thermostat setting, the air conditioning unit activates to cool the air. Conversely, when the temperature drops, the heating unit is engaged. Ventilation works simultaneously to regulate moisture levels and filter out pollutants. This dynamic balance of heating, cooling, and ventilation ensures that indoor spaces remain comfortable and safe, regardless of external weather conditions.
