Commercial Ventilation Duct parts
An HVAC duct is a critical component in heating, ventilation, and air conditioning systems, designed to distribute and circulate conditioned air throughout buildings.
The air conditioner duct works in combination with specialized components like the 18" duct mount temperature sensor, which provides precise monitoring for consistent climate control, and the duct air quality sensor, which detects contaminants for healthier air circulation. Other essential products include the sampling chamber for accurate air sampling, the compressor plug and compressor that drive the cooling process, and the control board that regulates system operations. In addition, the conductivity sulfide cell enhances monitoring efficiency, while the heat exchanger transfers heat effectively to optimize performance.
At PartsHnC, we offer ventilation duct parts such as 15" vertical drain pans, dual round capacitors, 6" flange duct temperature sensors, heater elements, and more from top brands like Johnson Controls and Honeywell.
FAQs
How often should you replace your air conditioning ducts?
Air conditioning ducts should typically be replaced every 10–15 years. However, replace sooner if you notice leaks, mold, or reduced airflow efficiency.
What materials are HVAC ducts made from?
They are usually made from galvanized steel, aluminum, fiberglass board, or flexible plastic materials.
What size HVAC ducts are commonly used?
Duct sizes vary depending on system requirements, but most residential ducts range from 6" to 14" in diameter.
What causes HVAC duct leaks?
Leaks are often caused by poor installation, aging seals, or physical damage to ductwork.
