"Had a water heater go back and they determined that it was probably still under Kenmore parts warranty (since only 2 yrs old) so recommended I first call they to see (and it was where I got a free replacement through Kenmore) rather than have them do anything, so I greatly appreciated that. Since they determined that 15mins into the service call, I had them also replace an old external water spigot that was hard to turn on. They did a great job with that, even replacing the bib pipe since it had rusted and had minimal breaking into the wall."

"I needed some help moving a washing machine and dryer into my laundry room after a renovation of a floor replacement. The company came out right away, was professional, courteous, and did an excellent job installing the appliances and taking care of our needs. I would highly recommend this company."

"Acclaimed Drain and Plumbing Solutions installed our SP3 Combo Whole Home Salt-Free Filter System. While the project took one day longer than originally estimated, the system itself appears to be working well. However, communication was lacking; the team never followed up to check on our satisfaction, nor did they provide the promised instructions on how to maintain our tankless water heater. While the system is largely maintenance-free, it does require a filter change annually and a recharge every 8–10 years. Given current inflation, I am concerned about the potential future cost of that recharge. Overall, the work was satisfactory, but I would have appreciated better follow-through and customer service."

"Great! Leonard did a great job replacing the existing gas water heater with a new gas water heater. Plus Cal's services the water heater (drains, cleans) after a year if you become a member of "the club" (well worth it)."

"It was an Angie's List Big Deal that I purchased for $29.99 for a diagnostics on the heating and A/C but I was charged more because I had repair done. They were good, there had been another company that had given me more information about replacing parts so that the air conditioner could continue to be used. It is old but the other company seemed to be more willing to do the work that it would take to keep the old unit going, and Trusted seemed to want more to just replace the unit. For me, replacing the unit would just be a very difficult thing at this time. He did repair and he was effective at that. I guess he just didn't want to have the whole job, he just would have much rather pop the unit off and get another unit on, it's just easier for them. I'd be more likely to look for somebody else to use in the future."

"Stephen was great! Very thorough checking for leaks and took the time to make everything look clean and professional. We just moved into our house and he also showed us how to use our water softener and care for our hot water heater. He really took the time to answer all of our questions without ever making me feel rushed and generally was very pleasant and kind to me and my family. Thank you Stephen!"
