Air One Tech was referred to us by our Weichert home warranty in order to fix a boiler that leaked in our basement. It took two weeks to order a part and when the company came back to fix and install the new part – they spilled new water and ripped upped old tile. They just left the mess and claimed that it was in that condition when they arrived. I have date stamped photos to prove otherwise. To add – the boiler still does not work and is now leaking from some other area. Air One Tech has refused to come back out to relook at the work and fulfill on their garuntee of service. They have refused to clean up the mess they made. They have completely dismissed themselves of the situation and are referrring us back to our home warranty company. NEVER USE THIS COMPANY! If I could give them NO STARs – I would. Horrible customer service and follow through.
