Business ProfileforCY HAVC Supply

******** purchased this **** ** split Unit(GREE-XXXXX) from this company which name used to be ** BEST *** in July XX XXXX, at a price of ****** The warranty is 7 years on compressor, 5 years on all parts and 1 year on labor. We started to have air leaking and copper pipe ****** issues in ******* so we have another company came and recharged the refrigerant. Then on ******** this unit is not cooling again. So we had the refrigerant recharged again. Then we figure this is not the final solution as it may continue leaking. So we got hold of the ** **** SUPPLY and they sent two contracted technicians in two times with no proper solution. We then had another vendor came by giving a diagnosis. The technician said this unit is not reliable and the installation was a ****** Mouse job "Found that the mini split system supplying the server room was installed very poorly. The pump is also very close to equipment and may cause water to leak on server equipment. A previous company charged the system with refrigerant a couple days ago. There is a leak and unable to visually locate it. Due to the poor installation and equipment, we recommend removing all existing equipment and materials and do a complete reinstallation. " Then after our insist, the owner of CY HVAC SUPPLY came. But he didn't do anything either to resolve the issue. Then in ******** the copper piper started to leak water. We had a 4th vendor came by ******* and fixed the water leak. But the unit is not cooling still after fixing the air leak and recharging the refrigerant. So it could be the issue with the circuit board, or another leak. We then turned to ** HVAC SUPPLY again for warranty. They kept arguing as before and then dropped our phone. At this point, we have no way to go but filing a claim. We don't want to deal with them anymore and we are asking for a refund on the unit, plus the repairing fee of $****.
