    I think he deliberately quotes low to get selected and then increases the price when he visits…read more Also he needs to stop exaggerated claims that are at least borderline lies. It seems he does not try to understand well what the customer is asking: his answer to my "why"s were not good. Details: He quoted me $150 to fix a low refrigerant issue. on visiting, he told me $260 saying that the system has 0 feon. That made me suspicios. The pressure of the system when off was over 200 PSI as shown in the attached picture. Suspecting that he was lying, I weighed myself with his 410 gas tank before he started putting in the refrigerant: 68.9kg. After he was done, I again weighed myself with the gas tank: 67.7kg. So he only put in about 2lb (1.2kg) of refrigerant, certainly less than 3lb. Even after seeing my weight measurements, he told me he put in 4lb. I asked him how did he came up with the 4lb number: he said by looking at the pressure readings: I think he knew he was bullshitting. The system label says it holds 68.8oz 410a (4.3 lb). so it was only about half empty. A 25lb gas tank costs ~300 so. the cost of 2lb 410a is less than $30. so he should have asked for $180 ($150+$30). After complaining, he did reduce the price from $260 to $200, which I consider fair (other quotes were $100-$250). My main issue is his deliberate-seeming low quote and what seems to be deliberate lying.

    These guys were awesome! Very responsive and when installing a min split in my guest suite. I got…read moreseveral quotes and they came in away below the others as well. Gracias Strong Cool!
