Question about an AC install gone wrong.
Hello! We had a new AC installed on Friday May 8th. That following Wednesday, the electrician from the company came out to finish hooking up the new AC (new to the house as well as it never had central AC). While he was working on it, the power to all of the outlets on the front of the house went out (this half is original). This includes our living room (where our internet router is and is our primary living space and is lit by only lamps), the dining room (has working overhead lighting), and our entire 2nd floor (where we have to use monitors for our baby while she sleeps). Oddly, the overhead lighting and the GFIs on the second floor still work. The wiring for these outlets is most likely knob and tube due to the age of the house (early 1800s).
The guy didn’t notice this and my wife asked him if he was going to turn the power back on before he left. He said he didn’t turn it off. So he went and tried to troubleshoot it (at an additional $352) and was unable to fix it. Luckily we had to leave for vacation that night and made an appt for them to come back on Tuesday May 26th for a fix. Well instead of a fixer, they send a quoter! They quote us $1000 for them to do another all day troubleshoot with 2 guys. If that doesn’t work, we are looking at a minimum $10,000 for total rewiring for the front of the house which will cause plaster damage we will also have to pay for separately if we don’t fix it ourselves. They are trying to say they didn’t do anything wrong during the install and that this probably happened bc we used to use a window unit last summer or a space heater this winter.
We were told by a friend whose brother runs an electrical repair and install company he believes that the AC is incorrectly grounded in the breaker box. I sent an email to the install company documenting that I’m afraid to run the new AC if it’s improperly grounded.
As of May 13th, we are without internet and power to half of our house. The install company is not taking any ownership and basically keeps asking us for more money to come out and fix it on June 4th. I have made them well aware that I have a 7 month old infant in my home and that on 5/19, the temperature inside the house reached 80°.
Any advice or history with this kind of issue?
Thank you in advance!
