I used them for my air conditioning, and they've done plumbing for me. I would rate the overall experience with an A+. When I was having air conditioning done, we had scheduled two or three appointments, and they would call and would tell me why they weren't going to be here because older people were having troubles with their air conditioners, and they felt like they needed to do older people first. I said no problem, that's just exactly what we need. I would highly recommend them to a friend.”

“I wasn't really there while they were there. It was an easy process. It wasn't difficult or anything. They replaced my plumbing line. I'd give them an A+. I haven't had any problems with it. I guess I really won't know if it's all fixed until I have any issues, but I haven't had any.”

“They were professional, courteous, on time, did what they said they were going to do and cleaned up. I thought they were thorough and well run. I had a pretty major leak under the slab that they had to mitigate. Given the situation, I'd give them an A+. First time I ever used them, and they came through in a pretty bad situation really well.”

They were able to send their plumbing guy out within a day or two. So it's just a pretty expedited and smooth process. There was a pipe leak inside the home. I think it was a sewage water pipe that the previous owner had nailed into with a nail. When we took out the nail, it started leaking. I would say they get an A overall.”

“That was a while back. They were fairly responsive. The guy that actually came out did a good job explaining what the issue was. They came out to examine a leak we were having and do kind of a minor repair to fix the leak. It was a leak in our bathtub that was causing water to come downstairs. I would grade them as an A.”

“We were very satisfied. Very reliable, they showed up on time. They gave us all the information, answered all the questions, they made recommendations, they gave us the cost estimate and stuck to it. They did plumbing, a gas line on the balcony to our grill and they did some electrical work. They exchanged a plug. I think that was it for last year. I would give them A+. I really don't have any complaints.”

However, when we first we called, they responded right away but they did some work but didn't find a leak until I called the next day because the unit was running but no cool air and our house was all foggy from the Freon leak and the air stopped cooling. I called again and they came out again, and fixed and replaced all. Then the final result was wonderful.”

“As always, Roland was on time and fixed the problem. He is always courteous and helpful. We always call and request him.”

“They knew exactly what they were doing, which was nice, and they guaranteed all of their services, which is the reason why we went with them. They're a reliable company. They came out for an estimate on a couple of things, but the main thing that they did is, we had an electric tankless water heater put in on the plumbing side. Then, the electrical workers came in to make sure it was all hooked up properly. We had a temperature issue, but that was on the plumbing side, and they fixed it right away. My parents had had work done with them, so they recommended the company to us. I would give the company an A-.”

“I like that they're honest. The three guys that I had out there were open and honest about what needed to be done and what didn't need to be done. They're very courteous and professional. The first time we had them come out, they installed an igniter onto the existing water heater, and then they put in a water filtration system. The last two guys were out for air conditioning work, and the second guy had to come out and put some Freon in one of our old existing air conditioning units. I would rate them as an A-grade company.”

“They're really professional in their attitude, they answered all of our questions, they took the time to listen to what it was that we were asking, they gave us the information that we wanted, and they fixed the problem. With the plumbing issue, we had a situation with our kitchen sink, which they fixed. Then, we had some questions about the performance of our water heater, and they answered our questions about that, too. I would recommend them to a friend or neighbor. I would grade the company as an A.”

“They just did everything that they said they were going to do. They installed a toilet and installed a water heater. I heard some reports about the company, and that is why I chose them.”

“They let me know when they're on the way, and they do the job right. They installed a faucet and a pipe. I chose them because people said that they liked the service. I would give them an A.”

“We've used them for years with no issues. They did some plumbing work recently. We used them for years—we just always call them. They're a grade-A company.”

“We've had them a couple of times. The whole thing is great, the service is good, the people they send out are very capable, and I have no complaints. They did two different things. Once, somebody actually cut our outside pipe for the water, and the water was all over the place. They came in and repaired that. The other problem was, we had a leak in the house, and they came in and looked at that. I would give them an A.”

“The people from Abacus know what they're talking about, and they do the work. They installed the NuvoH2O water conditioning system, and they put in a new hot water tank that heats as you're using it, which is just wonderful. They get an A+ because they really helped me out a lot.”

“They were very professional, courteous, and polite, and my wife was impressed with how clean they were and how nicely they explained the problems and the solutions they proposed. We signed up for their plumbing contract, so they did a general inspection and then diagnosed a problem with a drain. I'd rate them as a solid A.”

I think that they were more technically proficient than most I've had experience with. They were cordial and very professional—it was just an overall positive experience. I'd give them an A+.”

“Abacus Plumbing put in a new hot water heater. They got here when they said they would and did what they said they would do for what they said they'd do it for. I just knew a little about them from what other people had said. I'd give them an A+.”

“The plumber from Abacus came on time, did a good job, and left. He replaced the cartridge in the bathroom. I would give them an A+.”

“The plumber's knowledge and ability to fix our problem made it a positive experience. I had three plumbers out here before him. We had a water line break in the slab. He managed to isolate it and turn it off, so our foundation wasn't totally eroded. It was the weekend before Thanksgiving, the in-laws were coming, it had been going on for a week, I'd had three plumbers out here, and nobody knew what to do. The last one cut a hole in the wall and left a mess. The guy from Abacus Plumbing came out on Saturday and fixed it all and cleaned up the other one's mess. I cannot say enough nice things about it. We chose Abacus because they were the first people who said, 'Yes, we can send somebody out tomorrow. We will find the leak, we will fix it, and somebody will be there working until it's fixed.' They're A+. We have recommended them to other people, too.”

“Abacus Plumbing fixed a water leak on my line right next to the water meter. They were friendly, pretty professional, and got the job done as needed. I would grade them an A+.”

“I called them on a Sunday, they came the same day, and they repaired the problem in a couple of hours. They fixed a leaky showerhead that was leaking in the shower and behind the wall. I called someone I knew that uses plumbers often, and he recommended them. I would grade them an A—good service, and no complaints.”

“There was a pipe leakage—it had burst—so Abacus Plumbing came to see what needed to be done, and they did it. They came out early in the morning. Everyone else we called, it would have taken a while, or they weren't available. Abacus gets an A.”

“We were very pleased with Abacus Plumbing. They actually called and said that they could come sooner than they had anticipated, and they were able to save us and get the work done quickly. We were quite happy. They actually ended up having to replace the valve on the main that connects the water meter to our house. That was the main thing we called them out for, and they had to do quite a bit of work to do that. We'd actually worked with them a couple of years earlier and had good results. Abacus is an A.”

“It was friendly service. The guy from Abacus was really clean with his work and really friendly. I had a plugged drain in the sink. I would go with an A for them.”

“Abacus Plumbing fixed a clogged dishwasher line for me. In summary, everything was great. They did a great job, and I didn't have any issues with them.”

“They replaced a section of pipe that was covered with roots. I would give them an A. They knew what they were doing, and they did it well.”

“The gentleman that came to do the work was very pleasant and easy to work with. He replaced some pipes under our sinks where we had a leak, and then we had some old pipes that needed to be replaced, so he did that, too. My husband chose Abacus Plumbing. I tried two or three different companies, and I didn't like them, so I thought that I might try Abacus. Also, I heard from another homebuilder, and he recommended Abacus. He said, 'You might want to call Abacus. They do a good job.' I'd give them an A.”

“I was needing someone to come after hours, and the guy was really nice. They didn't fix it the first time, but he came back and fixed it. He found the problem—it was a plumbing leak. Abacus gets an A.”

“They did plumbing work. The plumber was friendly, and I would give them an A.”

“Abacus did plumbing work for us. The guy that came out appeared to know exactly what he was doing. He explained everything very well and went through the whole process with us—what needed to be done, what the costs were going to be, and so forth. Then, when he got the parts in, he returned and installed everything. We don't have any complaints. I would give them an A.”

“The service person from Abacus Plumbing was fantastic. He came out and inspected all of our stuff and made sure we had no problems in the house. He was able to get out here very quickly and solve my problem. Abacus is great, and they deserve an A+.”

“I liked the high quality of the work from Abacus Plumbing. They replaced a hot water line and fixed a fitting that was causing a leak. I would give them an A+.”

“Everything about using Abacus was good. The job they did, the friendliness, the customer service of the technician—everything about the experience was positive. I had a leak in my tub, so they came and replaced the pieces and installed a new faucet and faucet overflow. The technician was so good. They're an A+.”

“Abacus Plumbing has actually done work for us within the past couple of weeks. I had a plumbing problem with an unusual requirement, so by using resources that they had, they researched the equipment that I needed and came up with a product that is so new it's not even on the market yet. It's literally the only one that can solve the problem. It was a little bit of repair and replacement. We had a major repair, but this was a new part. By unusual effort on their part, they found this brand-new product that wasn't even on the market yet and couldn't be found anywhere else, and they fixed the problem. The gentlemen had fabulous attitudes, and they were very respectful of my home. They did everything in a timely fashion. It's an A+.”

“We use Abacus for plumbing. They fixed the toilet, unclogged the drain, and put in a plumbing fixture. They did an excellent job, and I would use them again in the future. They're an A+.”

“Abacus Plumbing has done some work for us in the past. They were out here three times. They fixed a clogged drain, changed a water heater, and fixed a water main break coming into my house. The quality of work they did was excellent each time. I thought the technicians were courteous and did a good job. I'd give them an A+, and I'd tell a friend or a relative to use them.”

“They showed up on time. They're very clean and left the area neat, and they're very polite. The last time I used Abacus Plumbing, they replaced two water heaters. The time frame they completed the work in was excellent, and the quality of work is excellent, too. The workers that came out were very nice, very polite, and were in uniform. I trusted them near my home. They called back, followed up, and it's all good.”

“Abacus Plumbing did work for me a while back. I thought they were excellent, and they did a great job. We had a leak that needed to be taken care of, so they took care of everything that was necessary and cleaned everything up. Their customer service was excellent. That was my first time using the company. I would give them an A+.”
