Additional Notes

Complaint: This company is hired to do annual maintenance of the convector units in our building, and has had this contract for some time. Among the services they are required to provide is to "clean the coil with cleaner", "note any deficiencies", and "inspect operation". Last Tuesday, May 6, they visited my home for the inspection. Yesterday, Tuesday, May 13, my downstairs neighbor informed me that my unit was leaking into her ceiling. I called Wright Mechanical and asked them to come out and reinspect the unit. The technician (one of the ones originally sent out to do the "maintenance") was unable to resolve the issue, but admitted that clearly the issue had been occurring for some time. The coil is badly rusted, and the floor beneath the unit is black and warped. I moved into my unit last December and had not until now had cause to use the AC. If Wright Mechanical had a) cleaned the coil, b) noted the deficiencies and informed me of them and c) fully inspected the operation of the unit, I would have known there was an issue and would not have used the unit, causing additional damage to my floor and my neighbor's ceiling. The fact that this has occurred in the past (as is evidenced by the condition of the coil, the floor, and my neighbor's ceiling) leads me to believe that Wright Mechanical evidently did not inform previous occupants of the unit of possible issues when doing their "maintenance".

Desired Settlement: I would like Wright Mechanical to cover the costs of repair to the floor and my neighbor's ceiling incurred due to their failing to inform me of the issue with the convector.

Business Response:

*** ******,

Thank you for the notification regarding this matter.

Wright Mechanical Services (WMS) did provide service to unit *** convectors as agreed between WMS and the Association.  The agreed proposal is attached for your review.  We provide the service to unit *** on May 5 2014 and the previous year on June 20, 2013.  Our service records show there were no issues found with the convector when serviced in 2013 and this year, 2014.  WMS has no record of service calls placed by the previous owner regarding leaks or for any additional services nor do we have record of the unit owner below *** calling in for water damage to the ceiling. 

We received a call from the unit owner of *** on May 13, 2014 indicating the convector was leaking water.  WMS responded the same day with the same technician that performed the service on May 5th.   As stated, our technician noted to the customer there was rust on the coil housing and the floor showed signs of previous leak issues.  The rust was found on the coil housing and is a normal condition.  The warped damaged flooring was from water leakage that occurred over a number of years prior to WMS association with the property and is the case for a number of other units in the building. 

Due to the age of the building and the condition of the equipment, WMS included the following language in its agreement with the Association. 


1. Due to age and condition of the convectors, Customer agrees not to hold Wright Mechanical Services responsible for damage to unit during service that may occur due to broken water lines, valves, condensate overflow or failure of equipment such as motor failure or thermostat failure.

While our contract has the above language to protect WMS for such situations, again only due to the age of the equipment and property, WMS will repair the ceiling in unit below ***.  I have addressed this with the Associations Board President and we will work together to arrange and make the ceiling repairs.  As for the flooring in ***, the damage to the flooring was due mostly to previous leaks and therefore WMS is not responsible for repairs.

Thank you for your time in this matter.
