Business ProfileforAffiliated HVAC Services

5/17 (Friday) technician showed up unannounced (was supposed to be here on Monday) unprepared to perform equipment run through and test defrost cycles, which is what we called and made our appointment for. He said he'd have to come back a different day because he didn't have time to do it that day. We never heard from them again about coming back.5/28 our coolers were all running at high temps, technician came to our shop clearly already in a very bad mood and proceeded to tell me that these coolers had to be full of product in order to run at the correct temperatures and there was nothing he could do. He told me to call the manufacturer (but "good luck because you're going to be on hold for 45 minutes"), I got through in less than 5 minutes and the manufacturer's rep told me that they absolutely do not have to be full to run at correct temperatures. The Affiliated HVAC Services tech was rudely arguing out loud with what the rep was saying to me on the phone. The manufacturer sent a warranty service person down to the shop to diagnose and fix these coolers, which he said could have been done by any HVAC tech who had the knowledge and skillset to do so. We received a bill in the mail for 1/4 of an hour from 5/17 and 3/4 of an hour for 5/28. We emailed them to address this issue, they did not respond. We send back a letter with the unpaid invoice explaining why we don't feel we should be responsible for the billed amount. They keep sending invoices with no follow up abou the real issue. The bill is only $104 but this issue is based on principal and the fact that their 2 technicians did not provide any service, if anything, unreliability, unprofessionalism, a terrible attitude, and inconvenience.
