"It was Saturday afternoon. When I saw water spreading on my basement floor, I called Nutmeg. Within 15 minutes, I got a call back from a tech. He said he could be here within 20 minutes, and he DID. He cleared the drain from the evaporation pan. All is well, and I was satisfied with the weekend charge. Super service. Have used Nutmeg in the past for my HVAC work, and will always use them in the future."
