Saved me over $300!!!! : )
5 Stars
Saved me over $300!!!! : )
My HVAC Co wanted to charge me $383.00 for a 15min install. During my 6mo free inspection after install, he came out to check out my system. After all said and done, he recommended i get a surge protector. That's when he quoted me that charge. I asked to see what it looked like, went to his truck, showed it to me and said that it will only take him 15 min to install. Of course I knew they always charge ridiculously for labor. I took a picture of it and told him I will think about it ; ). Why didnt they recommend it during the sale?? What if I did have a power surge and it ruined my Daikin system? So dissappointed at them.After watching a few install on YT, I saw how easy it was to DIY. I also asked a friend how to wire it. I took my time doing it to make sure I got it right. Made sure I turned the main breaker off and tested it with my volt meter to make sure it wasnt live. Total time around 20-30min!Totally satisfied knowing I have some kind of protection for my brand new Daikin.
