Best Commercial Refrigeration Equipment in Dallas TX

On April 21st 2020 called Xtreme Service to have them come out and take a look the a/c unit. The response time was good no problem there. The downside was that we felt like the technician seemed a little skeptical. He wasn't sure on a lot of things. He said that I needed a new defrost board. He did try to override the system so we can have air unfortunately it didn't work. Technician said that he will a have the defrost board next morning. He came back the next day Wednesday with the new board and installed it. He check a couple of stuff but not the entire system. Then after he left it worked for 2 days. Then we had to call them again another person showed up and he said this was the problem it was frozen and showed us. The other technician said in his own words he would checked other stuff. Then 2nd technician asked me could David come back out I said sure along as it get fixed. Sat the 25th David came back out told him what the other technician said. David said it possibly could be a leak and I was kind hesitant on what he said about the leak cause the freon would leaked out along time ago and it would of got hot right away. Just seemed like a lot of uncertainty. Then he put on the receipt that I refused pma which I didn't not refused I told him I had to look some stuff to move around in my account. David didn't explain the so called warranty correctly. On Saturday the 25th I called the office spoke to a lady I asked her the maintenance warranty she started to explain and then she put me on hold and never came back I hung up. Felt like we got the run around. On Saturday the 25th another from the same company came out to look at our siding and said he will get back with me on Monday the 27th for an estimate till this day still haven't heard back about the estimate. Also I felt Xtreme Service over charged us. We were told it was $800 then they knocked it down to $550. When I called the company the other day and to ask about the price he said $550 was for the labor. We called another company they came and did awhole lot more than Xtreme Service come to found it was the blower which Xtreme Service never checked.
