I really wanted to contract with a reliable company that i knew would stand behind their work, and Abacus was my first choice. I was not disappointed. I've had many opportunities to use Abacus. I've had AC units in some of my rent properties and i've recently had a Tankless Water Heater put in by Abacus and it was very smooth. I love the professionals that came, they were very courteous and answered my questions. They've always stood behind their work and have been a pleasure to work with. I would highly recommend Abacus to any of my friends or anyone that asks about companies that are reliable and stand behind their work. Abacus comes first to mind.

Very diligent and determined to fix problem. Abacus installers did NOT test A/C this past Monday, nor did they relight water heater and gas fireplace pilots. When new A/C was wired, old wires were used and actually shorted out connection to outdoor unit. Eric worked very hard to diagnose and fix this hidden: problem...great employee."
Doug and Allan were excellent. They were friendly, explained everything, answered all my questions, and left us convinced that using Abacus was the right decision.
Ramiro and Gilmar were professional. They took extra measures to ensure our house stayed clean and comfortable throughout the duration of their service. They answered all my questions, and seemed to provide quality workmanship. Thanks!
Andrew was a very great and most professional technician he went beyond and explained the system to me, showed me the differences in the new systems and what I have, I would extremely recommend Andrew for any freind or relative. Good job Andrew and thank you.v
Isaac did a great job. We had a lot of questions about the problem and he answered all of them calmly and professionally.
Eric was very professional explained what service he was performing and also checked my A/C unit as I mentioned the system was giving off a different odor after we used our heater a couple weeks ago. He changed the filter and performed a thorough check of the heating system.
It was a true pleasure to meet and work with this knowledgeable young man. I look forward to working with him in the near future. Thank you Abacus for all of your great support.
We found Andrew to friendly, informative, and professional. Excellent job!
He was very helpful and professional.
Isaac has worked on my HVAC several times and is always thorough, professional and pleasant. He is an excellent representtive of your company.
Really enjoyed Dan coming to the house and answering all my questions. Very knowledgeable and I will be requesting him for all my services coming soon. Really good employee and person.
Both men were professional & knowledgeable. Thanks for the continued support and excellent service for my family and home.
Abacus was there for us on Thanksgiving Day when our heat went out -- forever grateful!
Jose was great. It's the people who make the company. And it was a pleasure dealing with him. Good for Abacus!
The techs were very conscious of laying down protective covering inside the house; they kept me well-informed during entire installation process; performed very, very well on tricky, challenging installation (small attic space & had to use crane to lift outdoor A/C unit over 3-story house)!
Samuel did a great job-he called a few minutes before 0800; saying he would be here in an hour and made it in 50 minutes. He was very friendly and polite. He gave an explanation about the work, answered all our questions, and gave us estimates about work we will need done later.
Very professional and assured me that everything is in working order- thank you!
Michael was super. He performed exactly the tasks I needed, and he did it very quickly. Thanks!
A very pleasant and informative guy. Would recommend him to everyone.
Honest, up front with options. Represented ABACUS very well!
Jerry was very thorough and explained our issues well. I appreciate his candidness. Good technician.
He called before arriving (came a bit early which was great) and very polite and professional.
Monte was very professional and knowledgeable. I really appreciate his recommendation on how to keep the first floor warmer during cold winter nights. No one had ever explained this to me! So, I am thankful Monte was the technician who came to my home to do the inspection!!! I hope he comes back again in the future!
Your technician arrived right on time. I was leaving for work, but my wife was home for the checkup. My wife appreciated his punctuality, as she was going to run errands in the afternoon. Jaime was professional and did a thorough check. We are considering his recommendation to add a surge protector to the system.
John did a great job checking out my heating system. Thanks
Jose was amazing! He explained how the system worked and the installation process.
Professional, courteous, detailed, and thoughtful. Isaac showed up after I called David, the manager on duty at Abacus as a follow up to a service call. Isaac assessed the situation and provided a solution that met my timing and expectations. He was professional and courteous and validated why I do business with Abacus (even though your prices are pretty high) - the quality of service and the level of expectation. nice job. Rahul
Monte, explained the process very well.
Leonard was very helpful and took his time to work through several areas that we wanted him to look at.
Leonard was super nice and fantastic. He diagnosed the problem quickly and repaired it within minutes. Wonderful person
Gio was excellent! Very knowledgeable and personable! A pleasure to work with!
John did a fantastic job. I look forward to working with him in the future.
Doug and the other gentleman with him were very professional and I would welcome them on future service calls.
John was professional and knowledgeable.
He did a great job! Now just need to evaluate his recommendations!
Isaac did a great job explaining the problem and outlining the repair options. I am very satisfied with his service.
Always professional and completely thorough.
He was great and explained everything well. He did a very thorough job
Friendly, professional, and thorough. Arrived on-time and answered all of our questions.
Juan was polite when he introduced himself and his work partner. Asked if I had any questions. They both worked well. They did the job in less time then I was first quoted which was a good thing and a bad thing. I had to cancel an appointment because I was told it was going to take 4 hours to do the job when it actually took 2 hours. This was not Juan's or his partners fault. But being over quoted on a job was a annoying.
he was great. good personality also
Great tech. He was very knowledgeable, professional and quick. Thank you!
Darrell was very professional in explaining what needs to be done .......
Andrew did an excellent job inspecting & thoroughly explaining the findings. He was consummate professional, and exhibited a pleasant, well-mannered, and jovial demeanor.
Quan found that previous installation done improperly & tech that did quality check after installation failed to determine error with thermostat & was reason heater not working. I've had increased electrical bills since installation and now am curious if this is the reason.
Very professional! Stayed with the job until he found the solution. Very patient!!!!!
Jason was very thorough, friendly, and gave great info on how to keep our heater/air conditioning healthy and we always appreciate that.
Doug was awesome! Thorough, informative, and friendly! Thank you Doug!
Jose was very thorough and professional . Explained everything in terms I could understand
