What customers say
"We had ABACUS come to our home again and install a new faucet, garbage disposal and all the connecting pipes under the new sink. The experience couldn’t have been better. From start to finish, it was smooth, professional, and super pleasant. Tim Waltman was our technician, and he was fantastic. Super kind and polite, and clearly knows his craft. He took his time, did a really clean job, and everything works perfec…"
— Sergio Durante · Jan 6, 2026 · Google Reviews"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 …"
— Sherrill Jeter · Mar 4, 2026 · Google Reviews"Had Abacus technician, Ethan, came out for a 2nd opinion. Very honest appraisal and inspection. Will only recommend service that’s needed. I will use them again in the future for repairs."
— Jessica Tran · Mar 2, 2026 · Google Reviews"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."
— Gregory Bow · Mar 9, 2026 · Google Reviews"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."
