I called Abacus at 10:30 on Friday morning before the snow storm was coming into Austin. The electric fireplace was not working and I was concerned about potential loss of power over the weekend. Both an electrician and a plumber showed up and they waited to make sure that the the fireplace was working before they left. They were very professional and took a real interest in getting the job done. We are VIP members and they informed us about their services they provide which are included in the membership. I was so pleased that we were taken care of the same day that I called. If no work was necessary there was not to be a charge for giving a quote for repair. Repair was necessary and it was fixed within a reasonable time frame. Thank you, Abacus for the pleasant experience. ~ Marilyn C

Outstanding Service – Fast, Friendly & Fixed on the Spot! I couldn’t be happier with the service I received from Alonzo at Abacus! I was able to get an appointment this very morning—no waiting, no hassle. Alonzo arrived right on time and was incredibly friendly, professional, and knowledgeable. He performed a thorough diagnostic, explained everything clearly, and was able to fix the issue on the spot—quickly and efficiently. He didn’t miss a thing and made sure everything was running perfectly before he left. And the best part? The pricing was excellent—incredibly fair for such fast and high-quality service. I'm beyond satisfied and will absolutely recommend Alonzo and Abacus to anyone needing reliable, top-notch service. No reservations—just great results! ~ Leslie G

I had an AC outage and Abacus was able to come out quickly to get me repaired and back up and running. The technician Nick was provided tremendous customer service and was very professional. He arrived on time and was amazing with his quick diagnosis. He walked me through all the details of his diagnosis and repair recommendations. He presented me with several options and allowed me to weigh the pros and cons of each one in a very fair manner. Never did I feel pressured to selecting the most expensive option and I really liked that about the technicians on site. I really appreciated his ability to get me repaired and honest opinion on best path forward that will help this house cool. I couldn’t recommend this company more for your HVAC needs. ~ Travis T

A few months back we had an estimate for some AC duct work to improve comfort in one part of our home and were qouted a price. Well we finally got around to getting it complete. Today the 2 man crew showed up to start our project. A few minutes after starting they asked to talk to us. They informed us part of the work we had been qouted was unnecessary. They explained the reasoning and how the other part of the project would achieve the same results. This really impressed me and my husband with their honesty. Their honesty really shows they work for a company who is there to genuinely help their customers and not just to make a buck. This saved us from spending unnecessary money. We will definitely use Abbacus in the future for any of our plumbing or hvac needs. ~ Raquel B

Started our semi-annual HVAC service / tune up today, and Nik was incredibly professional and friendly. System isn't new by any means and is showing various signs of expected and unexpected wear and tear, so he walked us through the good news, bad news, options and recommendations. I'm glad we reached out proactively, and am looking forward to using Abacus for the foreseeable future. Follow up: replaced our AC unit, and Erick and Carlos were absolutely great. We were working at home and they were there for the majority of the day but we barely knew they were there. Took the time to show me all the work they did in the attic and around the condenser, made sure everything was working as planned, and cleaned up so you wouldn't know they were even there... ~ Tex P

This is my first experience with Abacus Air Conditioning repair. The whole experience was great from beginning to end. Martha took the call and set the expectation of the technician being at my place within 4 hours. She encouraged me to review their website for discounts. I found one for new clients. The Technician was here within two hours. I received a picture of him prior to arrival. Deandre was very professional and courteous. He provided quotes for labor needed. He also, provided before and after photos. His quote was exact and to the penny and no other fees were charged. The A/C problem is resolved and working great! Kudos to Deandre Rodriguez and Abacus Company. for an excellent job. I am an extremely satisfied customer. - Robert C. ~ Bob C

My 20-year-old tankless water heater started delivering hot water with sporadic gaps of cold water. I contacted Abacus using their online service request site. Within the day I was scheduled for a visit by a technician in the following week. The technician gave me status updates about his time of arrival and he arrived on time. He was polite and very knowledgeable and gave me options for troubleshooting, repair, or replacement. Due to the age of my heater, I opted to have it replaced and he scheduled installation for two days later. The installers arrived on time. They also were very polite and respectful of my house and within 3 hours had removed and replaced the heater. They installed it according to code. Everything works perfectly and I am very happy the entire process. ~ Ted D

Editing to add a new experience We had another great experience with Abacus, this time with Teddy. Teddy showed up on time, very polite, and very helpful. I showed him the main issue we were having with a toilet, and he immediately provided multiple solutions for us to choose from. While he was here, he gave us free estimates for other things around the house I asked him to look at. He came back the next day and had our new toilet installed in less than an hour. Another excellent experience and will continue using Abacus. Terrific experience with Omid. He explained what was causing the drain, gave me my options (including prices) for cleaning the drain, and clean the drain immediately. He was polite from start to finish. Would recommend and will be a return customer. ~ Evan L

This was the first time using Abacus. My husband called in the later part of the evening and VOILA...there was Hunter on the phone calling us first thing in the morning the next day sharing he would arrive in about 30 mins. He arrived on time and was an absolute delight, a professional and fixed everything with ease! We will definitely ask for Hunter if we have any other plumbing needs! Plus we will contact Abacus NOW, that we have had an exceptional experience (GREAT ONE), for some of our electrical needs, but that will have to wait till this fall. THANK YOU FOR PICKING UP THE PHONE, FOR BEING POLITE and PROFESSIONAL FROM THE VERY START and FOR MAKING THE WHOLE PROCESS "EASY" AND FOR HELPING US SO QUICKLY! Sincerely, Mr. and Mrs. McCullers ~ Tricia M

ABACUS came by for some plumbing work. The technician Dion was great. Very professional and explained things as he was completing the work. Very reassuring and knowledgeable you could tell he did a high quality job. ABACUS was great to work with. In a recent service call I had one of my air conditioners stop responding to the thermostat. ABACUS came out and did a thorough job of trouble shooting. It required new wiring so they temporarily put in an external wire to get things working. Installation team came back in a couple days to install the permanent fix. They did a great job! We bought the units from them and they stand by their work. They’ve alway been professional and trustworthy. I would recommend them for any HVAC, plumbing, and electrical work. ~ Bill A

We had a major electrical problem and called Abacus Electric, they came out the very next day and tried to fix the problem, Matthew Hicks was unable to after searching for hours. He required additional help to trace and find the problem. They ended up working for two days in order to find the problem and get it fixed, but not once did they act like they were upset about being there so long and working so late. They were very professional and diligent. I was worried that it would cost a lot because they had to come two days and spent so many hours working on this problem, but the price was reasonable. I am very satisfied. I want to say thank Matthew Hicks, Josh Lerma and the other gentleman that was with you, sorry I didn't get your name. We appreciate your service. ~ Rosalie B

Abacus was great, they handled a full replacement of 3 separate heating and A/C systems in my home. Daniel, who advised us on the replacement options after he inspected our old system, was also involved in the installation, and is just fantastic, he is extremely professional and conscientious, and a great communicator. I’ve never had someone explain systems and various options in that level of detail so clearly and patiently. Joe managed the team behind the install behind the scenes but came by multiple times to be sure everything was on track and he was just great. I especially appreciated the final tuning, air flow analysis, and walk through of the systems both Daniel and Joe gave us after everything was installed. The service options and long warranty are great as well. ~ John S

Our tankless water heater had stopped producing hot water when we returned from trip on Saturday. I called Abacus and they scheduled a repair technician to come Monday. Isaac arrived at noon and determined the unit had shut down. He restarted unit and then made certain hot water was flowing to all areas of house. He explained how the unit worked, reasons it could have shut down, made recommendations going forward. He was very professional, thorough in his explanations, including pricing and scheduling options should we want to replace our unit which is now 18 yrs old. We appreciated Abacus’s quick response and resolution to our issue. We highly recommend them for all plumbing repairs due to their professionalism, quick response, and integrity! ~ Karen F

I cant rave enough about Abacus. This is the second job they have done at our residence. Their team start to finish is timely, professional, and polite. Compared to some other service industry competitors in the Austin area, Abacus is head and shoulders above them. Today a small hiccup and road bump in our work. It was unbelievable how quickly, professionally, and responsive their whole team was. They fixed the issue that was 1 in a million and it was done right. I will have their team back to my house for any issues with HVAC plumbing or electrical. In a market where too many up charge and give attitude because its Austin and they can, Abacus is different. And for any or all of these reasons, they will continue to get my business over the others. ~ Dave K

Abacus has been my go to plumber for the last year now. They installed a new tankless water heater, repaired shower cartridges, and repaired valves to ensure I'm receiving proper pressure from the city line. They are all considerate and friendly and work hard to find solutions. My recent experience with Sean Sedia was a great example. For some reason, our water heater was not providing sufficiently hot water. Sean came out and attempted to diagnose the issue with the manufacturer. After many attempts and back and forth with the manufacturer, it was Sean to identified the issue (a $9 part had failed) and got our system up and running. He was very persistent in his attempts to solve our issue and did not give up. Very appreciative of the plumbers and Abacus team. Thank you Sean. ~ Alex Y

Abacus replaced my HVAC system and my Hot Water Heater. Since the first visit, everyone has been professional, knowledgeable, and explains what they are doing, and what they have found. I signed up for the VIP membership, and it is the best thing you can do. I don't have to worry about maintenance or any issues. Every technician and customer service rep I have talked with have been awesome. They leave the place clean, and before they leave, show you pictures of what they have done or seen. Five stars are not enough for them,, they deserve 10 stars,,, If you are looking for someone you can count on, look no further,, this is where you need to go,,I really cannot say enough good things about them, they are the best, and the best decision I could have made, you will not be disappointed, and be glad you went with them. ~ Jan H

I've used Abacus to change out my garbage disposal and this time around it was for our water heater. Both experiences have been great. Our water heater stopped working on Thursday evening, I called that same evening and I was able to have an appt scheduled for Friday morning. Teddy Linnell came out, assessed the situation and we were fortunately able to install a new water heater that same morning. He was kind, informative, clean and best of all, he didn't wake up my sleeping toddler while doing his work hahaha. Honestly, I haven't had a bad experience, I feel their pricing is reasonable and they are a quick turn around. I'll be reaching out to them to replace my electrical panel (whenever I'm able to save up the money). ~ Marli E

Abacus and their technician Pedro were an absolute pleasure to deal with. I was kept informed via emails and texts of the appointment date and time, as well as when Pedro was on his way and at his arrival. In the process of the requested yearly gas furnace inspection he was very gracious, informative, and knowledgeable about our system, what he was going to perform and afterwards, what he had done with pictures to back it all up. He took his time doing the job and in explaining everything in detail. His care and professionalism was demonstrated in so many ways, even to the point where he put protective covering over his shoes to walk three feet into our house to look at the thermostat. He then emailed his report and the pictures he took for me to have on record. I will use Abacus again and definitely request Pedro to be our tech. ~ David L

ABACUS Plumbing truly came to our rescue during a last minute issue in the middle of our kitchen remodel. They were responsive, professional, and quick to get someone out when timing really mattered, which immediately took a lot of stress off our plates. Technician Jared Melton was outstanding. He clearly knew his stuff and worked efficiently and was clearly focused on doing the job right, not just getting it done fast. He was calm, respectful of our home, and incredibly professional, just exactly the kind of person you hope shows up when things are already stressful. Overall, we were extremely happy with the experience from start to finish. ABACUS delivered when it counted, and Jared is a huge asset to their team. I wouldn’t hesitate to call them again for the next phase of our kitchen remodel. Highly recommend. ~ Sergio D

Called ABACUS to come check out the lost of water pressure and possible leak underneath the slab. Dustin was the first technician to come check out for my water pressure issue, he was very helpful and informative. Dustin and tech checked prices for other work and we saw ABACUS had discount for sewer cleaning. Told him I would like the service. Andres Barriosnueva came out and provided the service, he suggested we did a scope to see if we had a sewer issue. Andre was very informative. Scheduled that service and Donald came out to provide the borescope service. Donald was very informative and provided a quote for a service. ABACUS team was very informative and helpful. Will be using them in the future for the quoted work. ~ Eder R

Jason, the tech/journeyman who quoted the job was excellent. First, he listened. Then, he walked the house to clarify the problems, explored the attic with its extensive flooring and then gave me three possible solutions with pricing from which to choose. He then arranged a crew to complete the work the same day. Eduardo and Juanito arrived within an hour, worked efficiently and cleaned up as they went. They then explained the new 20 amp line, gfi plugs, breakers and switches they had installed until they were sure I knew how it all worked. In other words, what to do to reset wall plugs and breakers that might trip. Very pleasant and professional men who provided excellent service. Will not hesitate to use Abacus in the future. ~ Bob F

This is the second time I've used this company for a leak in my home and again they were awesome. I initially contacted another company, who charged me $100 and sent a plumber who stated that he couldn't help me and advised me to contact an AC repair person. I contacted Abacus who sent over a plumber who had no problem correcting the leakage and they waived the service fee. What I like the most about this company is the integrity displayed by their technicians. On both occasions there were opportuities to overcharge but they were quick to let me know when additional repairs weren't warranted. My technician was Michael and he was very honest, personable and professional. I have decided to become a member as I already know that this is the only company I can call and count on for honest, efficient service. ~ Barbara S

I lost all power at my home.😵‍💫. I called Abacus and a technician was dispatched the same day. Jason arrived and immediately identified the problem. My panels were a fire hazard and thank God blew out my power before starting a fire. Jason’s expertise combined with his customer service and genuine care and concern raised the bar to new heights and he walked with me and explained everything along the way. He made me feel like family and made sure I was taken care of. I felt confident with the decisions that I made. Brad and Walker spent 2 1/2 long days replacing my panels and rewiring my home throughout. I have to give Ms. Lucy, Office Manger/AP Coordinator a big thank you as well. You helped me breathe😌. I recommend looking into their Peace of Mind yearly membership plan. MY ABACUS TEAM WAS GREAT! THANK YOU ALL!!! ~ JoAnn B

I called for help late in the day and still was able to make an appointment for the following day. Alex arrived on time and I had received his picture before he came. He quickly diagnosed my problem in a professional, and efficient way. While doing the repairs he found a couple other problems which he discussed with me and I opted to have serviced. My home is older and hasn't had good maintenence. Before leaving he made sure he answered any remaining questions. Alex was friendly, competent, professional, easy to talk to, explained his action plan and reasoning, and efficiently fixed all my problems. Excellent work from him. I would definitely use this service again and will ask for Alex. ~ Elaine C
