Short story: they are great for quality and service. They were not cheap, but they were competitive on price. Read below for the long story. It is December, and we were having furnace problems, and a CNG repairman diagnosed a cracked heat exchanger and shutdown the furnace because of possible carbon monoxide issue ("red-tagged"). The furnace was 25 years old, so it was better to replace than to spend and estimated $1000 to repair. 1. The estimate: It is a week before Christmas, and we are without heat. We need to act quick! Called 6 contractors for quotes, and got quotes from 4 (2 could not do the work immediately). We made an appointment with Nutmeg for the same day our furnace was shutoff, and Quentin came right on schedule. He was extremely fastidious collecting the technical details for the install, and very helpful explaining precisely what our options and limitations were. Quentin was head and shoulders above all the others who came to give us a quote. Since our AC was also 25 years old and also not working great, we included that for replacement. In case you do not know, there is cost savings to do the furnace and AC together, since you save on some money on the labor that is common. 2. The install: Quentin gave us a quote on a Thursday, we agreed on a price Friday morning, and he promised an install on Monday (two days before Christmas). They prioritize no heat situations (as I expect all do). Indeed, Monday came, and an install crew of 4 guys arrived around 7:45am. They were very polite and efficient. They tore out the old furnace and AC, and had the new ones mostly installed by 2pm. We put in a two zone system with a multistage 96% efficient furnace, and an AC with 16 SEER rating (both qualifying for efficiency rebates and tax credits, that Quentin helped with). They also replaced the coolant lines, thermostats, and dampers for the zoning. The only minor glitch was connecting our existing house humidifier. For some reason, the humidistat panel would not work when everything was re-connected. They did not have a replacement panel on the truck, so we arranged for them to come back after Christmas. They returned two days after Christmas with a new panel, and had it installed in about 45 minutes, with no additional charges. 3. The bottom line: everyone wants fast, quality, and cheap. It is hard to get all three. We feel we got fast and quality, and a competitive, but not cheap price. For us, that was an acceptable trade off. We are very happy with Nutmeg and would certainly reuse their service.
