need hvac person in Jersey

I live in PA and my mother who lives in Kenilworth NJ (Union County) needs some furnace work. Do any of you Jersey folks know of someone I could trust.

Don’t know if you can trust any one east of the Mississippi. Just Kidding. Generally speaking the larger professional companies run the larger adds in the yellow pages Stay away from the one liners, brother-in-laws and next door neighbors. To be truthful I don’t see many HI’s posting on this board from NJ Good luck.
