Response from Diamond Quality Services
There were no on site services performed for this member because the members tenant did not show at the first appointment scheduled (during a time frame desired selected by the tenant) and because afterward the member decided he would not meet us to let us in to the rental property on a reschedule appointment we had offered to make/accommodate the member with. The rental property is located in east Dallas/Garland. We offered several times for the tenant earlier in the day, but the only time the tenant was available was a late afternoon appointment. It was communicated to the tenant that we would meet at the requested/desired time although being in east Dallas during rush hour is time consuming when heading back to Grapevine as we try and respect our technicians drive time and family time as much as possible. We made concessions to meet the tenant and the tenant knew this. One of the owners (Scott) personally spoke to the tenant and explained this. The tenant said he would be there as that was the normal time for him to be home. While in route to the scheduled appointment our technician called approximately 30 minutes in advance and even though no one answered or returned his call we made the decision to keep him in route to the members rental property because of the particular problem the members tenants were having with the AC system not cooling which was in September. After arriving on site at the members rental property in east Dallas our technician made multiple attempts to provide service but after driving an hour across town to east Dallas to get there at the agreed time our technician ultimately had to leave with no one coming to the door or answering his calls. Our technician went to the door twice and and a third time to leave his business card. Then left. We contacted the owner and notified him we would only go back if he was there to let us in. He agreed and then he decided at a later date that he did not want to meet us there, but he wanted us to meet the tenant. We declined. We understand the member received a refund from Angie's List because when the refund was granted to the member we received an email from Angie's list stating that the reason was because (no appointment given in time frame desired). Not accurate! What is completely true is that we accommodated the member tenants time frame desired at the original scheduled appointment. We arrived on time for the original scheduled appointment. We did all we could do before, during and after, to try and provide service to this member and tenant. The member did not reveal the no show in his review. The member in his review did not reveal that he told (Scott) that he did not want to meet us for a reschedule to let us in for services the member requested. We think it's critical to (all) members, as well to our own business and quality reputation that we indicate pertinent details that are known. Unless someone is willing to provide the facts that are known, at the very least should beg the question as to why conceal it? Or is there a hidden agenda? The information we provide is based on actual documentation be it detailed notes or other and we will always ascribe and share in instances such as this. If not then it could simply serve to imply that we do not care and most anyone then could make the assumption based on (the grade ccccc provided by the member) curtailing an explanation, that somehow we just dropped the ball or were flippant. As a company imparting quality to Angie's List members and to all our clients who receive service beyond expectation we have been clear that if we make a mistake (and we can) we stand up and take responsibility for our mistake and make it right. If we are unwilling to do that we are deluding ourselves as individuals and as a company would have been scratched from Angie's List years ago. Instead, we go forward. Our Mission Diamond Quality Services is a group of dedicated professionals with a winning team spirit, and firm understanding of our business. We have a passion to serve those in need of our expertise and problem solving capabilities while diligently providing service beyond expectation. Diamond Quality Services

Description of Work: I am very very thankful to Diamond Quality Services because they rescued me! I got home late Thursday night from work and my air conditioner was not working. I had used Diamond Quality Services before so I went online and purchased an Angie's List coupon for a service call and made an appointment through the online system--but the first available appointment would be Monday! This was the first weekend of 105+ degree weather in August! I knew I could not stay in the house all weekend because it was too hot for me and my small dog. I would have to board my dog somewhere because I did not have anywhere to take her. To my surprise and elation, Diamond Quality Services called me back and sent someone out at 9:00 a.m. on Friday morning! They diagnosed and fixed my very old A/C and when I asked for a tune up also, they converted the coupon I had bought for a trouble call into a tune up coupon, instead of me having to pay both! The first time I used them two years earlier they rescued me also--on a Sunday! I am very grateful and impressed with their professionalism and honesty, and also compassion for others. I was very happy to receive their Invoice and saw this statement at the bottom: "Proverbs 22:1 Choose a good reputation over great riches: being held in high esteem is better than silver or gold." Love it!

Description of Work: They had to repair and replace some parts on the blower motor of my AC. It went well. They did the job within two days after getting the parts and everything is good now. Their office personnel were very kind and professional and that's why I went with them. The personnel that came out was very attentive and professional as well.

Description of Work: I originally used Diamond on an Angie's List HVAC checkup special several years ago and continue to use them several times per year to service our two unit layout. Recently, I called on July 20 and received July 22nd service to replace a bad capacitor on our upstairs unit. The technician (Julian) suggested I purchase their Advantage Protection Plan for $149. This week, I recovered much of that expense when the downstairs unit blower and blower motor required replacement. I called Diamond on Monday morning, Oct 5th, complained of a loud noise from the downstairs HVAC each time the blower ran, and Michelle scheduled a same day appointment! When the owner was unable to meet that time, his employee (Julian) covered for him and diagnosed the bad blower unit and motor. Julian said he would return the next day with replacement parts. The miscommunication occurred when I assumed that would be early Tuesday. I called midday Tuesday and left a message. The owner returned my call and we agreed on a 4 PM appointment. Meanwhile, Julian showed up at 2 PM and faced a 40 minute time to complete the job before I left for a medical appointment. Julian and his helper got it done in time with no mess and everything working fine! Great service, in part due to having a tech who had worked here several times before.

Dear Member, Thank you for making time to review and also in mentioning the value you have experienced in our Diamond Advantage Protection Plan. The July service was handled by technician Cale at the time when you also became a new Advantage Plan member. The most recent as of this week would have been Cale and assistant Mike. Julian (assistant) unfortunately changed career paths earlier in the summer but I would imagine that he was with Cale during an earlier service this year. Once again, thank you for your support. As with all Angie's List members we appreciate the opportunity to provide you with service beyond expectation and look forward to working with you again in the future. Diamond Quality Services

The member was there when our technician inspected his system. The system was very old/aged and had multiple issues both at the condenser and evaporator therefore; recommended replacing the system based on the condition of the unit. The condenser coil was damaged and not repairable. The evaporator coil was rusted and leaking. The existing system could not handle the higher pressures of conversion to 410a so changing out condenser only was not a value option.

We have a passion to serve those in need of our expertise and problem solving capabilities while diligently providing service beyond expectation. Diamond Quality Services
