Replaced a fan on a 25 year old sub-zero fridge. Technician was professional and up-front on costs and did a good job. Gave free advice on what to look out for. I know it’s just a refrigerator, but it is an old school sub zero built in, little problems can cost over 1K with one of these things. Ended up replacing a condenser fan blade for under $150, also observed a minor issue with the compressor and fixed that for free (tightened something), and good advice. Thanks!!!
