They were always on time and worked diligently throughout the entire project. The installers protected my wood floors by putting down cardboard so they would not track dirt in and out and so that the equipment would not scratch the floors. The installation of my new geothermal HVAC and water heater was completed without a single hitch.

Is it actually 150 Amp? You mentioned that the seller is installing a new HVAC system without a permit and they are a construction company. What I would be concerned with is the 150 Amp service. Not unless it is a huge house with a lot of appliances and electrical load. We have finished the Home Inspection and are currently negotiating on the repairs so we're going to ask about the permits. Should I be concerned about the electricity needed to run a new AC system in this old house? Should it be upgraded to 200 amps?įurthermore, I called the city office and found out that the Seller does not have a permit to install the AC system nor one for upgrading electricity. The house currently has a 150 amps electrical system. The Seller (a construction company) is installing a new air conditioning system (with duct work).

I have a contract on a 1930s Arts & Crafts-style home in Virginia.
