Our verdict
Polarized 4.7-star big-box shop (50 5-star vs 45 1-star of 100 sampled): when techs like Tim or Rory show up on time the work is clean, but 38 reviews flag pricing complaints and multiple Yelp users report no-shows or 6-hour windows that close empty.

The evidence — in reviewers' own words
Critical
“Not an easy review for me. On a scheduled service time of 11-2 the Electrician finally contacted me and let me know that it would be 3pm before he arrived. I’ve been waiting since 10:30. He was pleasant and professional. There were significant differences in what I was told by the office and the Electrician. He quoted an outrageous price ($568) to change a circuit breaker and I asked him to leave. I have history as …”
“We called Abacus to come out and try and find what might have been a leak as we were using a lot of water every month. We were told on the phone that there will be no charge to come out and check it and that if we decided to have the work done the service call charge would be included in the work. The man came out and after checking all the toilets told us that the one in the half bathroom was running constantly and …”
“I am a member of their HVAC maintenance program, cancelling tomorrow. One of my AC units stopped working. We called to get priority service that comes with the membership, they came next day, this was great. The woman that booked it on the phone stated explicitly there would be no charge for them to come out and assess what was wrong. The repairman showed up and checked things out but immediately kept telling me …”
Positive
“Great service all around. Great communication around scheduling. Plumber was on time and did a great job. Would definitely use them again for other plumbing services.”
“Rory from Abacus came to fix one of the mini splits in my home (or should I say, help me with it, it actually wasn’t broken). I’ve had Abacus service people at my house for various things the last 2 years. Always on time, professional and reliable. I got quotes from 4 a/c companies (even Goettl which my family used to own and operate) and went with Abacus. Very happy with my decision.”
