My condo has an HVAC system installed by GSPH as part of a new condo development project in Portsmouth NH. The system has never worked properly since the day we moved in. We have essentially no temperature control in a large portion of our condo where temperatures have ranged from the 50's in the winter to the upper 70's yesterday. I'm sure as temperatures rise it will be in the 80's in our master bedroom. Nobody from GSPH ever responds to me directly. In six months' time they have never resolved the issue, they never seem to be able to schedule a date to send a technician, and their service has been terrible. Honestly, I am at the point of wanting to hire another HVAC company to come replace the whole system. I would never hire these people. read more
