I went to a home today to check a system that was a 2002 Trane split heat pump system, 2 ton and correct size for the 800ish sq ft home, lady recently retired from the Air Force and just wanted to know if it’s working properly since she’s seeing $275 electric bills, I checked her duct work best I could since she just had insulation blown in and was pretty hard to see everything but nothing blowing around up there and was hot so doubt any air loss, I said I’d put my digital gauges and an amp clamp on and check it out, when I asked if she’d like to see the gauges she said Oh Yes, she’s retired plane mechanic and some folks couldn’t care less about seeing anything but after she told me what she did for a living I figured she’d be interested, everything was working well within spec (I was a little surprised how well) and she asked for a quote to add mini splits in another part of the home that has a flat roof but also asked my opinion on installing Solar, I asked didn’t you mention you’re going to rent the house out? She said Yes that’s my plan, I said well I don’t see how that would help you, you’d be putting out any upfront $, responsible for maintenance and Not see any benefit on your electric bill but tenants will get the break on their bill As Far As I Know? So did I give her a good opinion?
