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
Note to Homeowners: This article is primarily aimed at the Home Performance industry. I strive for radical transparency, so I put this in the public sphere for you to read as well.
Energy efficiency rebate programs from gas and electric utilities have become pretty common nationwide. They give rebates for replacing your furnace or adding insulation to your home. While these programs seem like a good idea, they can actually…Continue
In addition to saving energy, net-zero technologies offer a plethora of health, safety, and environmental benefits; but achieving zero energy can be prohibitively expensive. In this interview, Lucas Alm and Dan Handeen…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
