Arrived on site per customer request of getting a furnace replaced. Took the necessary measurements and worked up some pricing for a replacement. Return air grill inside the home was 26 x 16. Tested for CO in the home found none.the new furnace install includes a new AMS furnace of equal size and blower capacity. Includes transitions to ducting and vent connections. Includes a new thermostat as well. Took half down to today to get the job started. Thank you for choosing CPI Plumbing and Heating Inc.
