"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."

"Do NOT use Standard Oil. They called us constantly ? sometimes 10+ times a day ? trying to earn our business, but once we were actually customers, they did nothing to communicate important information like when our contract was ending or what the renewal process was. We received a vague email saying our contract would expire soon, but nothing about automatic delivery continuing or that any action was required. So we assumed service would end and found another company with reasonable rates. Then Standard Oil showed up unannounced, delivered oil we didn?t request, and charged $0.80 more per gallon than our previous rate. When I called the first time, I was told someone would return my call within 24 hours. That didn?t happen. When I called again, I spoke with Stacey, who was rude and dismissive from the start. She told me she could not send cancellation paperwork, then abruptly put me on hold and hung up on me. She also claimed someone had already cancelled my account but still coul"
