ER Hall Heating, Cooling & Electric

My heating unit is about a year old installed then start having problem. I don't think they are honest to me. I kept calling them to come out fix the problem, they said will call back but never did. Called them back, kept having excuses not coming out to fix the unit. No heat in the winter for 2 weeks. Tired of them. I called a different company; came out 2 hours later, the unit fixed in less than half an hour. ER Hall Heating definately is not trust worthy.
