DO NOT USE THIS COMPANY! Over charges for most of their services and may replace parts that may not need replacing. Was told that my main board needs replacing when they replaced it themselves within a year’s time. They once sent a technician who came to “fix” a heating issue and left after about an hour, said that everything is working now and that there was “no charge” which was strange to me because no one works for free. Come to find out the next day my system was not working correctly and they had to send a manager out to fix the problem. The system has never worked correctly since. So once again I called last month regarding a heating issue and was told that my Damper Actuator needed to be replaced for $1500 so I paid half up front for them to come back the next day and tell me all I need was to replace my thermostat; they didn’t replace it with a Lennox thermostat (Which is the brand of AC unit that I have) but an inexpensive $135 Honeywell that took the technician less than 30 mins to replace and charged me the entire $750 that I paid the day before. I understand installation costs money but $615 for 30 mins seems ridiculous! When I called the company to try and get some sort of reimbursement none of the managers returned my call. Only after attempting on the fourth call after a month or so did a manager tell me that the $750 price is what they charge to replace a thermostat. This seemed to me a classic bait and switch; the sad thing is that I’ve used this company in the past trusting them but who knows if I really needed all the things they recommended. It’s hard to find honest companies who hire honest employees who do good work these days. I will NEVER use ABACUS PLUMBING, AIR CONDITIONING & ELECTRICAL AGAIN.

I had a really positive experience with Abacus Plumbing. From scheduling to the service visits, everything was smooth and professional. Nicolas handled our plumbing inspection and was outstanding—very knowledgeable, professional, and took the time to clearly explain everything. Soufiane completed our HVAC inspection and was equally thorough and professional. Both were courteous, respectful of our home, and left everything exceptionally clean when they finished. That level of care really stood out. It’s not always easy to find reliable service these days, and they exceeded expectations. I would absolutely use them again.

Sedrick provided an excellent experience from start to finish. He was incredibly personable, honest, and took the time to explain everything clearly so I felt comfortable and informed throughout the entire process. I never felt pressured at any point, which I really appreciated. He answered all of my questions patiently and made what could have felt overwhelming feel easy and straightforward. I highly recommend Sedrick if you’re looking for someone knowledgeable, trustworthy, and genuinely focused on helping rather than selling.

We have been working with Abacus for 15+ years; overall, they've been really good to work with (the bulk of the work is A/C). I am writing this review because their latest work was outstanding and fixed a bunch of issues. We have Abacus check our a/c and heating systems twice a year - summer and winter. The estimate we got this summer proposed replacing our AC units , which was extremely unexpected and not cheap. We requested a more senior technician to explain why this was just coming up, and they sent Jason Finlay. He is very knowledgeable about airflow - which was really helpful as the air in the attic wasn't circulating correctly. Unfortunately, we ended needing an overhaul of our system - which was much more expensive than the original estimate! But we are more comfortable on how the system is working. I appreciated that Jason was always available to answer any questions we had, including drawing diagrams of the work being done. The teams Abacus sent out were always professional and very helpful. So, my thanks to Jason, Jose, Hector, Eric, Michael and Pablo (I'm sure that's not a complete list.) Thanks to Abacus.
