"Mr. Brian Langford made all the arrangements with the installation of our gas hot water heater from Lowe's via McCarthy plumbing. He was extremely helpful,patient, professional and available to answer all questions. Due to his approach to his work, we will be working with both companies in the future. Only concern I have is the warranty between Lowe's and AO Smith Hot water heaters. Once the heater is installed, Lowe's severs ties. If there is a problem with the hot water heater, you cannot return it to Lowe's although it was purchased through them, this is clearly stated on the Hot water heater in bold writing."

"Wonderful. Joe, Nelson, and the entire team did a great job. Polite, friendly, and efficient. Cost-effective too. We will definitely consider using them again for the inevitable kitchen and bathroom remodeling."

"We originally found AMS via Angie's List, and the owner came out very quickly to do a free inspection and talk to use about everything he was seeing -- high potential for mold within the walls of the shower, and other possible areas (on drywall of opposite side of walls, floor, etc.) He showed us all readings on the tools he was using, talked to us in detail about what he recommended -- namely, complete destruction of the tile-walled shower due to multiple instances of bad grout (old shower) and the resultant mold problem within the walls as well as on the floor of the shower. He also recommended some touch-up painting with anti-mold paints where water spotting occurred on our main level ceiling, rather than a more complex/expensive and in his view unnecessary ceiling patch. His crew was excellent, keeping things very clean and on schedule and luckily no major issues were found besides demolishing just the existing shower and raising up the old linoleum flooring followed by completely painting all exposed areas with Aftershock anti-mold primer paint to minimize problems in the future. He stayed at the estimate of about $3K for this work as agreed. (I eventually put in a new shower and floor myself.) For his second visit, he came out for another free inspection of some mold exposed in a main level bathroom ceiling when some plaster that had been wet down a few years ago when doing some cleaning broke away. This was a very small mold spot, and had a companion of some other mold shadowed behind wallpaper. AMS did another free inspection of this problem for me today, and advised that it was something I could definitely handle myself - ceiling and walls were bone-dry all around the area and it would be simple to just remove a patch of the wallpaper (which we plan to remove in this room anyway), scrub the mold with appropriate cleaner, re-plaster the small area of the ceiling that would need it, and then paint with Aftershock primer paint. He even gave me recommendations on places to get all my materials, including the brush I would need to match the existing ceiling texture. Even when I offered to pay for the inspection, he refused -- just asked me to write up a couple reviews, which I'm happy to do. I'm the type of person that likes to find high-quality businesses to form relationships with. As much as no one wants to use a mold remediation service, I would definitely call AMS again if I need to."

"Excellent company! My water heater stopped working on New Years Eve. Unfortunately, the water heater is behind my HVAC, so they had to remove the HVAC, remove the old water heater, install the new heater, and replace the HVAC. They did a perfect job. They also replaced the freon in my HVAC, because the prior repairmen didn’t add freon. In addition, they fixed the jets in my spa. The team arrived on time, displayed professionalism, and cleaned up afterwards. I would definitely hire them again."

"Jerry's Plumbing & Heating (Jerry's) was the assigned plumbing contractor in a home warranty plan that I've had for years.  I've used Jerry's in the past for small repairs but nothing of this magnitude or complexity.
Over the weekend of December 13-14, I suspected that my well pump had failed (no water) and made the necessary phone contacts.  Jerry's representatives were at the house Monday, December 15, in the mid-afternoon.  After they confirmed that the pump had indeed failed, they explained what they needed to do and we subsequently agreed to contract terms.  Jerry's people then returned to their shop to get the necessary repair parts. Once they had the parts, the on-site job supervisor, Doug LNU, said we'd have water before they left that evening.  Jerry's people got started late Monday afternoon and worked until nearly 12:00 midnight the same day.  As Doug had earlier represented, "we had water before they left."
When I was younger, I worked in a construction trade.  In the intervening years, my wife and I have owned a no. of homes.  Without reservation, I can say that I've seen few companies or their people work as hard or diligently the way these guys did either making repairs e.g., replacing a roof or installing an HVAC system.  Based on the experience that I had with Jerry's, I would recommend them w/o reservation.

"At 7pm on Saturday the 15th, In the middle of the Presidents` Day holiday, the value on my tenant’s apartment radiator started to leak at the rate of 1/2 c every half hour. My house, and the radiator, is 111 years old. I frantically called two 24 hour emergency plumbers and none of them came through. I then called Magnolia, who I had never used before, and Jose Vilche came to my house 40 minutes later. He had to drain the radiators and shut off the water flow as he could not remove the valve, but about 8:20 the next morning he arrived with his assistant, Angel, to cap that radiator and refill the system. He returned on Tuesday, as I had to work on Monday, with his supervisor who was finally able to remove the valve. The radiator stays capped until Tuesday the next week (accommodating my work schedule) when Vincent and Angel install the new valve. I had them also install a new drain valve on a second apartment radiator. So now, after all the draining and bleeding and testing for water balance, the radiators are functioning better than they ever had before. While Magnolia is not inexpensive, the cost was definately worth my peace of mind. Jose was in constant contact with me, he arrived exactly on schedule, explained each step along the way and worked diligently on my horrible problem until it was resolved. Thank you Magnolia- this was a stressful time for me and I was very satisfied with the service I had received!"

"We had a pipe burst early in the evening during one of the severe cold snap and called several plumbers.  We were told it would take anywhere from 1 to 4 days before anyone could get to us.  Constantly Running said it would probably be the next morning, but if they could get here sooner they would.  45 minutes later, one of their plumbers called.  He came out and promptly did the work.  The next week, their dry wall person came out and repaired the ceiling.  They were very prompt, professional, and courteous.  I felt they were very reasonably priced, as well.
