Additional Notes

Complaint: In 2008 we contacted Deljo to install a Mitsubishi Ductless Air Conditioning system at our home. Deljo instilled confidence in the system and commented that our house was a perfect fit for such an installation. The first summer it worked great but every spring since then the system has lost refrigerant and needs to be replenished at my expense of $250 to $500. During the first trip to fix the system Deljo claimed that leaks were normal in these systems and took no responsibility for their installation. In 2012 they began adding a chemical to 'seal' any leaks in the system. Of course this didn't work. Other service reps from Deljo have told us that these systems should never leak, so even within the company they can't get their stories straight. Just this year (after the product warranty expired) I paid them more money to conduct a leak test. Of course no leaks were found (so they can continue to charge me annually). To conduct the leak test they had to drain the system of refrigerant; however, they didn't keep the refrigerant for re-use and then charged us additional money to fully fill the system. Not sure what they did with the 4 pounds that were in the system but I thought they could re-use it. 5 days after this the condensing unit was making a screeching noise in the morning and completely shut down later that day. Deljo now wants $3500 to fix the condensing unit (hopefully); however, I will still have a leak. Alternatively, he tells me that a replacement condensing unit would not be compatible with the interior units so for $11,000 I can have a new system...that might still leak! Really? I contend that the breakdown of condensing unit was due either to the 'sealer' that they put in the loop or that the system was not filled properly. Other contractors have told me that leaks should never occur and that they cause stress on the compressor because the system is not properly pressurized. I think it was the leaking that eventually led to the condensor failing. I feel duped by Deljo because they took my money each year. They even convinced us to have a service contract with them because it would save money on the annual repairs that they knew we would have. It's unfortunate that a seemingly reputable company can't take responsibility for their own installation and products.

Desired Settlement: The air conditioning system has not worked since the second season. Even on of Deljo's service technicians said these systems should last 12-15 years. I'm asking for Deljo to replace the entire system in its entirety with today's equivalent products by the same manufacturer at no cost to me. We've paid them enough already.

Business Response: Initial Business Response /* (4000, 11, 2014/07/16) */ We have been in contact with ****ery ****** in regards to his A/C issues. We made a no charge visit to his home and conducted a refrigerant leak test. We are at this time in contact with the manufacturer in regards to repair. *** *******/Deljo Initial Consumer Rebuttal /* (4200, 13, 2014/07/16) */ (The consumer indicated he/she DID NOT accept the response from the business.) While the response describes the current status of the issue it does not propose a resolution; therefore, this issue can not be considered resolved at this time and the case is still open. Final Business Response /* (1000, 16, 2014/07/21) */ Deljo has been in contact with **** ******, and we made a return visit and an addition leak check at no charge to him on his 6 year old Mitsubishi system. We are curretly waiting for some direction from Mitsubishi,in regards to repair or replacement of the out of warranty unit. Consumer Response /* (2001, 23, 2014/09/11) */ 9/10/14 The consumer indicated ONLINE that the business responded to this complaint to his/her satisfaction. He/she also stated: Please be aware that Deljo replaced the outdoor condensing unit and has warranted the system for another year. At this stage the matter may be considered closed.
