Air Distribution System

HVAC installation costs depend on the type of system, equipment size, efficiency rating, installation complexity, ductwork condition, labor requirements, and optional upgrades. A professional HVAC evaluation and load calculation help determine the correct system and installation requirements for a home.

HVAC maintenance is preventive care intended to inspect and maintain equipment before problems develop, while HVAC service is a broader term commonly used for professional work performed on an HVAC system, including maintenance, diagnostics, repairs, adjustments, and component replacement. In other words, maintenance is a type of HVAC service, but service can also involve diagnosing or correcting an existing problem.

HVAC includes heating, ventilation, and air conditioning systems that work together to control indoor temperature, airflow, humidity, and air quality. A complete HVAC system may include an air conditioner, furnace or heat pump, air handler, ductwork, thermostat, filtration, ventilation components, and humidity-control equipment.

HVAC systems can help reduce some airborne allergens when they use appropriate filtration and are properly maintained, but filtration is only one part of indoor-air-quality management. EPA recommends combining source control, adequate ventilation, moisture control, and supplemental filtration or air cleaning. A suitable HVAC filter can capture airborne particles such as pollen and dust, while humidity control can help limit conditions that support mold and dust mites.
