A: It's similar to top-of-the-line heat pumps from companies like Lennox and Trane. But, unlike the competitors, Brazzle's total carbon footprint is substantially lower because it doesn't use HFCs or other high-global-warming-potential (GWP) refrigerants.
We don't have a precise decibel rating yet, but we know that you and your neighbors love a quiet night's sleep, and quiet is a top priority for our engineering team. The noisiest part of a heat pump or air conditioner is its compressor. We are reducing compressor noise with sound insulation technology borrowed from automotive brands like Lexus and Mercedes-Benz. We also use a multiple-speed compressor that uses the low (quiet) speed setting most of the time.
How does our heat pump actually work? Draw a diagram.
I want to show that the CO2 stays outside. Preempt any safety questions about this.
Explain how heat pumps are 300-400% efficient (or more).
On its own, the Brazzle Heat Pump can heat a home when it's as cold as 10°F outside. [TODO: refine this number.] Fortunately, for really cold days, Brazzle can be paired with supplementary heating such as an electric heating element or (gasp) a natural gas furnace (just for occasional use on very cold days)
