Report
They did exactly what they said they would do, when they said they would do it and with the highest degree of expertise and professionalism. Their pricing was very fair and their guidance was excellent. All of the electricians they sent to my home were polite, courteous and considerate. I will use them for all of my electrical needs in the future and will recommend them without reservation to my family, friend and neighbors!

Chris and his family do a fantastic job start to finish. With covid things were harder than typical yet they still did right by us. Sold and installed a 20K generator with whole home auto transfer switch. Never again will we lose power. They handled all the permits and coordinating with other contractors. Service: Installation

Report
My Generac generator worked fine for 7 years. JHACS took over the maintenance contract in April and then the storm hit this week and the generator didn't work. They sent two guys over who spent an hour looking at it (and poring over large bound manuals which did not inspire confidence) and then left. 2 other guys came the next day, spent half an hour and then told me it needed a new stator (which would have to be ordered and takes a whole day to install).
The office suggested I might want to just buy a new generator! I emailed them asking for cost to fix the one I have and how long it would take and they replied " When I have a minute to breathe I will provide an estimate". Generac told me to get a second opinion when I told them what JHACS said about the stator needing replacement. I cancelled my maintenance contract with them now and they won't even give me a pro-rated refund of the annual fee.

I have to say that this company is honest and they provide excellent service. My wife has not been happy with the company that installed our generator as it didn't work properly once installed. I received a letter in the mail from Generac regarding my plenum and decided to contact JHACS as they are a certified dealer. JHACS came to diagnose the plenum issue and they serviced my unit. I am beyond pleased and will be calling them to enroll in their service agreement for generators. Quality service! Thank you JHACS!
