HVAC is an acronym for Heating, Ventilation, and Air Conditioning. These integrated systems regulate indoor temperature levels, control humidity, and maintain proper air quality throughout your home or building.

Standard residential HVAC filters typically need replacement every 1–3 months. However, households with pets, occupants with allergies, or environments with elevated dust levels should replace filters more frequently to maintain optimal system performance.

Standard recommendations include setting your thermostat to 76–78°F (24–26°C) during summer months when you're home, and 68–70°F (20–21°C) during winter months when you're home. You can modify these settings according to your personal comfort preferences and energy efficiency objectives.
