A new 2 ton unit with new a-coil & line set installed here runs me: $1600-$1800.

Butts and Rios texted each other with directions on how to enter the home, according to the complaint.After Rios arrived at the home, she allegedly texted him that he should knock.Rios responded, “Open it, homie will…he opened it with a knife,” according to the complaint.She then unlocked the door, allowing them to enter, prosecutors said.When the victim approached the door, Rios attacked him with a metal bat and then one of the men discharged a firearm at him, according to the complaint.The victim suffered cuts and bruises to his head.

Coil cleaned?

Another good place to wipe is the back of a refrigerator, do so during your annual refrigerator maintenance when you are cleaning the coils.

This will probably take a few hours and you can't have any wood or metal touch the carpet. or you could spend a few days cutting small fibers out and have a bald spot in the carpet. either way charge them accordingly.hope this Helps,R
