Mario was very prompt, and very helpful, in dealing with our failing gas furnace (an old Goodman). He recommended a reliable, mid-priced Carrier for our 650 sq. ft. unit (in a low rise hard-loft conversion). The installers were very good and they had to work hard in a very tight alcove/space just above the washroom! They also installed a new Honeywell thermostat. Everything is now functioning really well (and with far less noise). So my wife and I were really pleased with the entire job, from beginning to end!
