The reason behind the low rating is the price they charge to come and look to see what the problem is.
I called last night which was starting to get someone to come here and look to see why my tub it flooded when I took a shower she said she would have someone here within 30 minutes and I said no wait till Sunday she asked me what time i said after 10 she said ok from 11 to 12 the technician will call you 15 minutes out so you know he will be on his way. so when the technician arrived he spent around 10 minutes with the shower discovered it was nothing might just been a fluke with my shower curtain and then proceeded to tell me well since I'm going to charge you a $149 you might as well get this package for them to look over all my plumbing and to come back service my AC and heater in the appropriate months
On their website they list that they come out and do free inspections for estimates but since there was nothing to be done so I guess that's why they charged me but a hundred forty nine dollars for 10 minutes of your time that's ridiculous
