I was reminded by a young lady's phone call that it was time for my reverse osmosis filters to be changed as well as the filter on my kitchen's cold water line. I set up the service to be done and was called by Jose Ortiz, the service manager that he would be at my house between the hours of 11:30 and 1:30 pm. Lo and behold, the doorbell rings at five minutes to eleven and Jose appears early! What a relief not having to wait the extra two hours. Jose was efficient and very affable, explaining what had to be done and replaced something that he said was installed wrong when the original system was put in. Very quickly done, very efficiently installed and finished within a half hour. I'm very pleased to advise anyone looking for an RO system or water filters to have AHW do the installations! Thanks to Jose!
