Trane...they cost a little more upfront but are worth it for the long haul. The heat is transfered to a blower unit which pumps heat/air throughout the house. This is an older unit but works like a charm! I have it serviced on a quarterly basis to ensure optimal condition. Service runs about $200.00 per year for this...but well worth it. Dominion Power is the utility company. Some months run as low as a little over $100.00 and some in excess easily of $300.00.
What's your bill & company?
