I was impressed that the technician called in his supervisor to consult on a unique problem that was not at all routine. Good teamwork—A.
The install crew was prompt and efficient with their time, they cleaned up very well after completing the job, and they were very professional. We're very pleased with our new heating and A/C.
The experience was great. I will use them again, and I will recommend Abacus if the opportunity arises—A+.
Outstanding in every respect—A+.
Great service. Not only did they check all systems to make sure they were working properly, they also cleaned things I didn't know were disgusting.
Never have to worry about the quality of work done.
I liked them. I thought they did a great job, and I'm very pleased. I would use them again. They did mostly air conditioning work and a filter, and they did some other small things for me. Also, I had an electrical part that needed work, and they did a good job. I chose them because I had heard that they were really good—I wanted someone that knew what they were doing and would do a good job. I'd grade the company as an A.
They seemed to know what they were doing, and that's what I liked about them. They worked on my air conditioning unit, and I'm getting ready to have some plumbing work done and probably a little bit of electrical work, too. I would give them an A.
I used them several times before. Their workers are very professional and knowledgeable. They show up on time, they don't try to oversell you on things that you don't need, they're realistic about what's going on, and they're very helpful. They did air conditioning repair work. They get an A rating.
They're very personable, and they are professional. We had them install an air conditioning and heating system in our house, and they service it two times per year, as scheduled. I think we picked them out of a Best Pick Reports book. I would grade the company as an A.
