As techs familiarize themselves with the nuances of a heat pump, there are a few common problematic areas they must concentrate on to ensure the equipment runs efficiently and effectively for years to come.
The use of ductless heat pump HVAC systems has broadened considerably since they were introduced to the U.S. market decades ago, but their technology isn’t familiar to all technicians or in all parts of the country.
There is a formula that successful contractors use to answer such questions and generate customer interest in duct upgrades. Their approach focuses on the facts about what an HVAC system is doing — they don’t share opinions or use smoke and mirrors.
A new duct sizing calculator from ASHRAE and the Air Distribution Institute (ADI) allows HVAC air distribution system designers to more accurately size ducts, especially flex ducts under varying amounts of compression, based on research results.
