Here's one for the electrical gurus out there. I have a new house with a heat pump. When the heat pump kicks in, every electrical device in the house has a massive power sag. It's so bad that you can hear it in the microwave, bathroom fans, etc. The lights practically turn off (then immediately back on).
I had the company that installed the heat pump check it out. Their service tech spent several hours out here with several different meters checking everything out. According to him, the system is well within its specs. He did agree that it the power sags are a bit excessive though.
I'm no stranger to residential wiring. In fact, I did all the electrical work on my new house. (I even impressed the electrical inspector, and from what I hear that's pretty hard to do around here.) I went through all of the documentation that came with the heat pump and verified that I'm using the proper gauge wire. I also used some online calculators to double-check that the gauge is suitable for the amperage and length. I've triple checked the connections and verified that everything is tight.
I'm at a loss now for what to check. If anybody has any ideas, please let me know. I can provide pictures and diagrams if necessary. It's beyond annoying now. Help! Thanks!
