Air Conditioner Maintenance in Winnsboro, TX 75494

“I had just put in a new capacitor a week ago and our side of the house was not getting cold. I have an older American Standard unit for our Master BR side of the house and a bit panicked about Labor Day weekend coming up. Called Jon Wayne at 9 am and they had Justin out by 11 am and it was low on freon! Even the expense of R22 could not express how pleased I was with their response so I can plan on a cool weekend with the family!! Highly recommend these guys and I just met them. Will use from now going forward! Thanks Justin and Jon-Wayne Company!”
