How old is your heat pump?

[Ron]

R-454b has an ignition temp above 900 degrees. I don’t really see that being an issue.

Understood. See also Data Center Guy, I.E. Computer Geek.

Buy one online and do it yourself. Have a guy hook up the lines and charge it. That's what I'm gonna do. My mil just paid 15k for one,for a 1200sf 1 level, but I think she got hosed.

I'm looking here. A buddy went this route and replaced his for about 5k. He had a 23k quote, which was a little high.
