Harp Mechanical LLC's Connecticut HVAC licence, HTG.0399313-S1, is active on the state registry under the holder H.A.R.P. MECHANICAL LLC. A 2024 customer, who wrote that they had been a customer since before the company was bought by a much larger corporation, said they were called less than 12 hours before a winter service appointment that had been scheduled 4 to 6 months earlier, because of a lack of personnel. That 2024 customer said the appointment was rescheduled, and that when they called about a missing confirmation they were told a supervisor had bumped that week's scheduled appointments during a cold snap because the company expected emergency calls.
I have posted positive reviews before and I’ve been a customer long before they were bought by a much larger corporation. I continue to be bombarded both by text and by email offering services from this company, but was called less than 12 hours before an appointment that has been scheduled 4 to 6 months before for winter service at the end of October due to a lack of personnel. The appointment was rescheduled for tomorrow between eight and 12 (Tuesday 12 324. I am used to getting notifications both by email and text confirming an appointment and had not heard today so called in at 1:30 and got somebody who was very nice who assured me that I would get a callback probably very quickly. It’s two hours later and I contacted them again. I was told that due to the cold snap the supervisor who told them to bump all the appointments that were scheduled this week because they expect an emergency calls. this is certainly understandable, but given the fact that this company bombard me telling me to ask them for services and schedule them when they can’t keep their own schedules. I find it both bizarre and disturbing. I’m afraid they have gotten “too big for their britches“. They clearly make promises they can’t keep
