I provided an estimate for two new systems in a home. For the furnaces, I recommended a Carrier Multi-Speed 2.5 Ton Electric Furnace & a Carrier Multi-Speed X-13 3 Ton Electric Furnace. For the air conditioners, I recommended the Carrier 13 SEER 2.5 Ton Air Conditioner and a Carrier 13 SEER 3 Ton Air Conditioner. Included in the estimate is a 1 year free service maintenance agreement.
