Called Hawthorne to come check why the pilot in my water heater wouldn't stay on. Ivan, the technician was very friendly. He told me it was the thermocouple and it would be about $359 to replace right then, but proceeded to tell me I should replace my water heater since it was old. Seemed reasonable since it was installed 13 years ago. When he quoted me $1800 for install I started to realize what kind of company this must be. I told him I would call them back the next day so I could do some research. At that point, and I guess to be expected since I didn't fall for the criminal act, Ivan's tone changed and he became very short with me. I've called three companies since then for quotes and all have quoted the thermocouple for half the price as Ivan quoted and $800-$1,000 less for a new water heater. I certainly wouldn't recommend this company based on my experience.
Update: the owner called me and refunded my money for the inspection and listed to my concerns with the technician. Changed starts to 3 for that as I appreciated the concern.
