Show notes for How to Meet Your Energy Credits with Jonny Nylen!
Today we are getting the word out about the new WA energy code. So we have expert Jonny Nylen to share all of the changes with us.
I’m already impressed with you today Jonny!
How long have you been working in the HVAC biz?
I started in 2008, which isn’t that long, but I ran my own business along side working a full time job. So, I know a lot about the industry.
I’m looking forward to getting a few rentals so I don’t have to work as much.
I have a degree in HVAC, and have worked every job in the industry!
Sounds like you could write a book.
I’m a native Virginian but I won’t ever go back because it’s too pretty out here (in the PNW).
When I came out to the PNW I was hired by a refrigeration company, and have done system design and retrofit. As well as creating a course for them.
Then I became a GC for 2 years, but last year I became just a designated HVAC contractor. I’d rather flip houses for myself.
So, let’s jump into it. I am no expert on this stuff.
I will share a really cool report with you guys that breaks down everything that I talk about today.
But let’s kick it off with how heat pumps work.
With this energy code… it was delayed until July but the governor decided to put it into effect right away.
The biggest things is… as of Feb 1st 2021…
So there’s a code for WA on Feb 1st but there’s other code for each city that will be specific?
Some of the changes the City of Seattle are looking at is how the major alterations are affected. So whenever you open up walls you have to update to the new code.
Total up all your window and you need some numbers… U factor, R factor, and other factors and numbers. These go into a calculator. And some of that goes into the heating code calculator. You used to just go off of the square footage of the house. But now… Using the calculator helps you size things.
There are no more furnace rebates.
We are switching to heat pumps in this state. Most people think they don’t work below 40 degrees, but they do, and I’m going to explain how.
Heat pumps are air conditioners with a couple extra valves and switches outside the unit.
I can use a heat pump to create a duel fuel system.
To explain how a heat pump works I need to explain HVAC.
Liquid is not compressible, only vapor is. We have a heat pump that’s going to make vapor compress. Well if you have cold air running across a hot coal. We are condensing a hot gas into a refrigerant.
