A new study from the National Institute of Standards and Technology (NIST) revealed that poor installation of air conditioning and heat pump units often leads to unsatisfactory energy performance. This research took three years to compile, with the help of surveys, field evidence, and various measurements for modeling. The most common installation errors included leaky ducts, improper refrigerant charge, oversizing of systems, and restricted…Continue
Mini-Split Heat Pumps are Quirky and Still Effective
The name "mini-splits" generally refers to heat pump systems with one outdoor unit and one or several smaller capacity air handlers. The efficiency of their operation comes via the inverter compressor and variable refrigerant…Continue
The most recognizable and commonly used mini-split system is the wall-mounted ductless system. They’re seen all over the world and are starting to become noticed and used here in North America, particularly in homes with small heating and…Continue
GUILTY! Once upon a time, I would have scoffed at mechanical engineers and contractors if they'd ask me, as the design architect, for a bigger room to put the HVAC (heating and air conditioning) equipment in.
"Are you crazy? And give up valuable storage space???"
They might have also ask me for dropped soffits and vertical chases to run the ductwork through. To which I would reply:
"What?!?! That's not consistent with my innovative and beautiful design! The…Continue
As someone who works with material and energy inefficiencies,…Continue
