This company was the kindest and most honest I have ever worked with. I explained A-Apex Heating & Air Conditioning's report that I needed to replace *all* my duct work but that when I had looked at it, only a few patches were needed. Rita, who took my call, was so very patient and assured me that her company would be honest about what was and was not necessary. Scott came out and reported that while improvements could be made to make it more efficient, replacement was not necessary and repairs would not prove themselves cost effective. Scott took time to talk to me about what to look for in future contractors (no money up front, insured for liability and workman's compensation, etc.) and did not try to sell me anything I did not need. He took photos of the issues with my A/C and went over them with me, promptly provided an estimate and will be our go to in the future. I cannot recommend this company enough.

They were wonderful. They called me back after hours to set the appointment. The serviceman was outstanding. He explained what he was doing as he did it. I asked some questions about why the master bedroom was colder than the rest of the rest of the house, and he told me that there was no insulation. He even helped me with how to brush my dog and was very friendly. He didn’t rush the job at all, and was just great!

Great experience. Service man did a full check of the unit, both outside & in the attic. While the unit is old, he wasn't giving the "doom and gloom" news about having to replace it immediately like others who looked at it previously had. He added freon and told me that I could still get a few more years out of it. He wasn't there to sell additional services that weren't necessary. This gained my trust. I would definitely use them again in the future.

There was no service performed and no record of any missed or unreturned calls to this member. The member was one of the many members responding to a big deal and we experienced an overwhelming influx of calls for scheduling. Unfortunately, a handful of those calls went straight to voice mail. All recorded messages were returned. Had he left a message I, Rita would have returned his call. Please check our storefront for all our Diamond Quality Service specials. Thanks, Rita.

The member purchased 1 cooling tune up from Angie’s List, but when we got to the home we found out he had 2 units. The member asked us to do the other unit for the same amount And he would pay for it. The member would not have issued us a check if we had not completed the downstairs unit. The check which the member gave us for the work we completed on the 23rd was unfortunately washed in a washing machine and was unable to be deposited the following day. The next day I Rita, called the member and politely asked him to reissue the check and he said that he would. The member never mentioned being unhappy and now 9 months later he posted this review forgetting he still owes us. The member never re-issued us the check that was ruined. The invoice remains open for payment, for the work we completed July 23, 2012.

The member purchased one system tune-up from Angie’s List, but had two units. The member decided she would pay us direct for the second tune-up on site if we would do the other system while we were there. That said, we also honored the same coupon price for the member. When we arrived to perform service/tune-up and checked the systems for proper refrigerant levels (Freon), we found both systems had been previously overcharged. This is identified not by just measuring operating pressures, but also measuring subcool and superheat levels which tells the real condition of the refrigerant levels. Unfortunately, many air conditioning technicians only look at system pressures which actually shows minimal information at best and in no way is indicative of an accurate refrigerant charge. A proposal was given to the member to appropriately recover excess refrigerant which will prevent premature compressor failure and also 1 drain pan which was starting to show evidence of rusting through. The member chose to have no service work performed. Overcharging a system with refrigerant is not uncommon, since it is easy to assume that a system not cooling properly needs more Freon. This is routinely not the case. Some of the most common issues found for lack of proper cooling is a dirty condenser coil, dirty evaporator coil, or most commonly a dirty air filter. Of course, there are many other potential causes, but the previous three are the most prevalent. We would also report the member never paid for the 2nd system we checked and diagnosed, which is still open on our books. We are amazed by the inaccurate description this member served us with, while at the same time does not follow through with paying for services the member received. I would expect someone not happy with a service would contact the service provider for clarification or the ability to make it right. Most problems are from a lack of communication or understanding. We could have easily walked the member through why we said the system was overcharged so the member could have spoken with the second opinion from a point of understanding and accurate questions could be asked to verify the results. We, at Diamond Quality Services, realize that we have an obligation to help every member we serve by giving them an honest assessment of any system issues present at the time of diagnostic. Every member should know that if we find an issue we will always let the member know about it, and offer our solutions which, in most cases, saves the member from a much larger repair bill down the road. We will continue to diagnose system issues and recommend solutions while providing each member we serve with "Service Beyond Expectation". Thanks, Customer care

Was left without AC for several days even after the new unit was installed.
Description of Work: One A/C unit was installed, but was unable to get it to work properly with the thermostat. As a result, it did not turn on during the hottest part of the day. Although the service person came out numerous times, had to call in another A/C company to get the system to work properly.

The review by the member is inaccurate. On July 31 2012, we replaced a condensing unit (outdoor unit) only since the member did not want to replace the complete system. After installing the condensing unit and testing we found the blower motor on the furnace (indoor heater) was overheating. The furnace had been damaged by a component failure or power surge previously. Once the blower motor was replaced the system operated normally. In September the homeowner was having problems with the thermostat on this unit so the member chose to replace it with a unit purchased at a local store. The member contacted us with an intermittent problem. I, Scott Peterson, went to check out the operation at no charge. While I was there the system was operating normally. I gave the member my cell number and told him to call me when the problem was occurring so I could head over quickly. A couple of additional trips led to no solution since by the time I arrived the system was working. I met the members spouse on the last time out and she said she was so frustrated she hit the wall by the thermostat and it started working. I checked the thermostat wiring at thermostat for proper wiring again and everything looked okay. I proceeded to take the thermostat off the wall and found one of the thermostat screws to be loose. This was the cause of the intermittent problem; the members installation was not complete even though it appeared to be. Loose connections can be very problematic to identify since the wire will heat up and lose connectivity. I do not understand the review from the member since I corrected the problem that was not caused by us, and did not charge him for the additional service calls. It is odd the member is reporting 6 months after the work was completed with no negative calls to us at any time and the inaccuracies the member reported.
