Diamond Quality Services

Arrived early (30 minutes) after confirming that it was okay to do so, completed the work quickly, explained everything he checked off and was done before the weather got bad. Very good impression.

They came when they said they would and did their inspection. It's hard to evaluate their work, since they didn't actually do any.

It went great. I was mixed up on the appt date but they waited 15 minutes and I arrived within that time. I felt they did a thorough checkup of my system. They also took the time to explain what was going on and what they tested for. They also changed my furnace filter in the attic.

This whole experience was excellent. Three different people worked on the systems over 2 different days. They arrived on time, demonstrated quiet, competent professionalism and gave us clear and complete descriptions of everything they did. The work was accomplished quickly and completely. They did work inside and in the attic, and took special care not to track in dirt after being outside. The work in the attic was accomplished completely and faster than they estimated. I will definitely use them again when I need work done on my heating/air conditioning systems.

We had all the vents and return air ducts of our 1968 built home cleaned. It was DISGUSTING to see what they removed, especially in the return air vents. I cant recall the gentlemans name that performed the service, but he and his wife were very personable, clean and efficient!!! I was skeptical, because I heard duct cleaning doesn't do much- I disagree with that theory! I saw what they looked like before and what they looked like during and after.... I am glad we did it! I can even smell a difference!

I called Rita just after closing time on a Monday evening. She was out of office, so since it was not an emergency, I offered to call her the following morning. When I called the next morning, she greeted me like an old friend, and she set up call, promising me service today. She called an hour before Aaron came, as she said she would. Aaron showed up right on time...what a good guy! He asked a few questions, found the problem, and offered to take me up to the attic and show me how to fix it myself next time. Really great experience. The next time I have air conditioning trouble, this will be my first call. Thanks Diamond, and thanks Angie's list

Mr. Scott Peterson Owner Mr. Alan Vaughan Owner Diamond Quality Services 1527 West ST HWY 114 STE 500 Grapevine, Texas 76051 August 18, 2012 Dear Mr. Peterson and Mr. Vaughan: In response to our advising you on August 12, 2012 that we had electric bills of $244 and $370 for the last two months you visited us on August 14, 2012. You tested and looked at our C/H system. Following that you submitted an estimate ($15,575) to replace that C/H systems with new units. We advised you that due to the huge amount of the expense we would be seeking three other bids from Angie's List members. That was done. Each bidder was provided a copy of your proposal, minus pricing and company information, along with a card containing our contact information. The bidder visits took place on Wednesday August 15 and Thursday August 16. The contract was awarded on Friday August 17, 2012. You did not receive the contract and here is why. Scott and Alan, you both visited, checked the house inside and outside and gauge checked the outside A/C unit. You were the only one of the bidders who did not go into the attic of the house. That was the first place each of the other bidders requested to see and then inspected. Most disturbing is what the first bidder discovered. He has been in the C/H business for the last thirty years. He found that two ducts running from the A/C to vents into room ceilings were completely severed. They were spewing cold air into the attic. That is why the front dining room and my office had not received A/C at all during the last 8 weeks. The bidder went to his vehicle and found a full roll of duct tape. He spent the next 30 minutes using the full roll of duct tape making emergency repairs to the two completely severed ducts and another duct that was about to be torn open. I was in the attic with him. I was horrified to see the severed and torn ducts and how the poorly attached Radiant Barrier is starting to separate from the ceiling and is beginning to fall down. Why are the ducts coming apart? Because you did not use sufficient duct length and as a result the weighted down ties are severing the ducts. Scott and Alan why did you not find these things yourselves? You did not have enough time or concern to even check the attic. You are the only one of the 4 bidders who did not see the attic. The others all ask to go and see the attic first. Yes at ,age 70, I was in the attic three time last week, not a good thing for me to be doing. I hope you will understand why our trust in you is lost and our disappointment in you as a professionals in heating and cooling is beyond description. Charles J. SpohnAnn E.

I was disappointed in them. Aaron came out and told me my drain plug needed cleaning and he wanted to charge me $175 more. I questioned him and he told me to contact Diamond. I was surprised that this service was not included in the deal. There was some miscommunication. Service is a broad term and I assumed service mean they would include taking off the panels and cleaning out debris and drain plug.

He arrived on time, did everything as promised. He was very thorough with everything and I am very happy with the services.

Serviceman Aaron was punctual, professional and got the job done to my expectations. Very good experience.

Over all it went great. the serviceman called 15 minutes before my service window even started. He was there at 1:10 for a 1-3PM appt. He was very professional and answered all of our questions.

We called DQS requesting that they diagnose the non-functioning A/C and provide an estimate to repair or replace the ductwork at the pier and beam home we are purchasing (as the initial inspector had identified these as problem areas). The initial appointment went very smoothly and they were right on time for our appointment. However, after diagnosing the A/C and inspecting the attic ductwork, the technician told us that his Company does not go underneath houses (we told them it's a pier and beam home with ductwork beneath) and would not inspect the ductwork down there. This was disappointing as this is where the majority of the damaged ductwork is. Furthermore, we sent them our initial inspection report identifying the problem areas and stated it was a P&B home so there was no reason they wouldn't have known. When we called DQS to complain about the lack of an underhome inspection, they were very defensive and somewhat unprofessional. They made no attempts to address our concerns, provide a refund, or even point us to another HVAC company that WOULD do the job. In the end, we had to hire another HVAC company to do the job, incurring yet more costs.

I have received excellent service from this company over the past 2 weeks. They came out and did a quick repair on my A/C correcting a mistake made by a previous contractor. They took the time to educate me about my system and truly treated me like a valued customer. I was a new customer when I first called them but they prioritized my service call just as if I had used them forever. I will definitely be a customer as long as I am in their service area!

The technician arrived promptly and went over all 16 points of AC tune up with me. As a new home owner, it was very informative to know how and what is needed to maintain AC for optimal efficiency. I would recommend Diamond Quality Services to all for AC maintenance ... in this Texas heat... it's essential.

Even though the repair was not complete the first time - they did properly diagnose the problem and returned to complete the repair at our convenience.

The service guy that came out did a good job. He found a problem and I told him I had a Home warranty company that it should be covered under so he wrote everything up that was wrong so I could give the information to the warranty company. The warranty company said they would not repair it unless it was broken.

This is the cheapest overall for air duct cleaning in the area using there coupon if you only have one AC system. They did the job, scheduling is very fast. Will hire again for future needs.

Read above.They contacted me within 48hrs and set upthe appointment. They called 3 hrs before and told me what time they expected to be at my residence, and the time was precise, and they kept it well.Aaron was the service tech, and he climbed up into the attic and checked the furnace fan, and the filter, and than he went outside and checked the A/C compressor, and ran some checks, it was low on Freon, the price included up to 2 lbs, and he added about 1 and 1/2 lbs. He was polite, straight forward, and I never got the impression he was trying to snow me or add additional services. He said everything checked out, and the unit was in good shape. I was very impressed. I highly recommend Aaron and Diamond Services, they do Great work and they are honest! Wow!

He said our unit was working fine and we would use this company again.

We are very happy with the service.

Overall the service was fine, and quick.

I had a little trouble getting them to call me back at first but as soon as we connected, I was well attended to. Technician arrived on time, assessed my airconditioning unit, offered advice in economic ways to keep my home cool. Seemed knowledgeable and thorough.

THE TECH. ARRIVED PERFORMED THE SERVICES I ASK FOR, I NEEDED FREON AND THAT WAS DONE. THE COMPANY SECRETARY IS VERY RELIABLE AND HELPFUL.. I WAS VERY PLEASED WITH THE SERVICES I RECEIVED.

Their quote was reasonable. They were professional, and they were honest.

They came promptly.checked my system. they discovered that my ac had a leak. I was not able to persue repairs at that time.
