The National Comfort Institute Inc.’s (NCI) mission is to help its members implement HVAC and home-performance contracting through easy-to-use strategies. That mission was accomplished at its recent annual summit, where the focus was on the best practices involved with selling and installing air upgrades.
To understand airflow, one must have a firm grasp of the rules driving its characteristics and behaviors. Many of the most complicated issues a tech encounters often tie to an airflow problem, so let's look at five airflow rules that can help anyone in the industry master the airside of the profession.
HVAC contractors are always looking for a way to differentiate themselves. Addressing duct leakage is a big opportunity. This is something building professionals are concerned about, so it should be an area of focus for contractors.
These temperature-related issues are often corrected simply by renovating the duct system to cure duct leakage and air-balancing issues, which created pressure-related problems in the building. There are instances, though, when you can have the perfectly designed and installed HVAC system and these temperature complaints still exist.
The average home’s ductwork leaks 30 percent or more. And while some model building codes now require duct-leakage testing and sealing, there is still a significant amount of work to be done — and a significant amount of energy to be saved.
Air Care, a Chandler, Ariz.-based HVAC contractor, announced that it is providing Aeroseal duct sealing with the purchase of a new air conditioning unit. The offer applies to all new air conditioning units purchased from and installed by Air Care for a limited time.
