Called them after our HVAC system quit working, due to our dog (probably) chewing through wires. The guy repaired the problem, charging us nearly $300, which seemed high, but we had no issue with it since we didnt know the nature of the problem. We didnt think there was any problem until our utilities bill increased from $85 to nearly $500. The utilities company sent a guy out to check on the problem, which he identified as the heating pads not shutting off when the A/C switched on. Called Hughes back to look at the problem, and the guy looked at it and said that the problem was our one-year-old Ecobee, advising us to replace it. I did not think this was a sound diagnosis, as it essentially rested on the astronomically unlikely coincidence that our thermostat went bad at the exact same time he was doing the repair work but for unrelated reasons. Even though Im not an HVAC expert, I spent ten years in computer repair, and I know a bad diagnosis when I hear one. When I brought this up to the guy, he told me hes been doing this for 20+ years, and when I still wasnt convinced he was right, he walked out of the conversation (I was away from home, talking through my wifes phone) and he left the house, telling my wife as he left that he unhooked our heater entirely, leaving my wife and four-month-old son without heat in February. We called another HVAC company, and the second I said **high utilities bill** the tech I spoke with immediately knew what the problem was and told me exactly what the utilities guy had discovered before I even gave him any additional information. He came out the next day and told us that the wires for A/C and heat were touching each other after the Hughes person shoved them back into the box, and this was an extremely common issue that any HVAC person should have been familiar with. He also told us that the way the Hughes guy repaired our broken cable was not the proper because he disconnected our auxiliary heat (maybe not a big deal in Florida, but still not something that he should have done, if he even knew that he was doing that). So the competent HVAC guy ran a full new wire and fixed the Hughes guys mess and charged us only $85 (when I told him what we paid Hughes, he was flabbergasted). We also had the utilities company professional come back out and verify that the HVAC unit is no longer having the problem it had after the Hughes person messed with it, proving that his diagnosis of our Ecobee was incorrect. For all the bluster about **Ive been doing this for twenty years** this guy clearly has no clue what hes doing, and were out roughly $1,000 (maybe more, as we dont know how much this is going to cost us on the next utilities bill yet, for the days it ran before we got it fixed). Had we trusted his misdiagnosis of the thermostat, we would have been chasing an issue that wasnt a problem, costing us even more money and leaving us without heat for God knows how long before we would have gotten it fixed. The man is arrogant, and his arrogance prevents him from learning how to fix what are apparently extremely commonplace issues in his chosen profession. Steer very clear of this company.
