"I paid an excessive amount of money to replace the heating system. The sales rep gave us comfort that everything will be done right and the two experienced and fully licensed professionals will be doing the work and that there is a no-excuse warranty, 1 degree guarantee, and 10 years on both the service and hardware. It just so happened that after the install, I told the installer I smelt gas and to check everything. He simply waved it off and said it's fine, give it some time. I told AJ Perri multiple times that there is a gas leak and I asked them to rectify the situation. I called them multiple times to send someone to fix the issue immediately and urgently, but they refused to commit to any resolution and won't send anyone until the gas is turned off for the whole building. I explained that its a condo and that the unit itself in the utility closet has a separate gas shutoff valve. Knowing this, they refused to remediate the gas leak."
