Abacus Plumbing, Air Conditioning & Electrical

Rhiannon N.

My brand new, overly expensive 20k air conditioner that we bought from them isn't working. It's the end of May in Texas and 100 degrees. I've called 3 times in 24 hours for help. Nothing. Nobody has even returned my call but each time I call I'm told they will call me back shortly. Unreal. All of us slept in a pool of sweat last night.

Oh and when I had them come out for plumbing a few months ago, the guy knocked my makeup into the toilet and gashed the wall about 4 in long.

Very very expensive and the absolute worst service and help.

Brandon Martinez came out to diagnose our air conditioner and absolutely knew all things AC. He looked at multiple areas of the units and went in the attic to check out our duct lines. He also went over and above by hosing off the condenser on the outer unit which was clustered with dust, dirt, and grime from 10+ years of usage. Brandon was very open with what certain parts of the unit might be at risk in the future and also with how to diagnose problems on our own. Overall 10/10 for Brandon and his work.

On another note, they are offering me only $3000.00 to void a 15 year warranty. Utterly Ridiculous. To think someone would give up fifteen years of warranty for the measley of $3000.00. You just can't trust these people from the start to the end. In the beginning the salesman stated I would get a rebate from the city for energy efficency, our unit after install didn't qualify!!!All Lies!!!!

The service man calls me and said he is on his way. I confirmed that I am there and waiting for him. Three hours later I called to check and see where he is and they tell me that he went to the house and my husband said I canceled the service? number one. I am not married. Number two. If he called and confirmed it with me why did he not question why someone would say it was canceled? I have had the worst experience with them and they were not even apologetic about their service man being so lazy that he doesn't show up for the job , and not confirming that he was possibly at the wrong house. Or did he even go out to do the job? I will tell all of my friends how horrible the experience has been with Abacus. I am waiting on a callback to let me know that I am getting a refund.

Wanted to provide detail about my experience with the Abacus Team, who installed my AC and heating system. Pedro, Danny, Mauriono, and Marco were efficent and took a lot of pride in their work.
BJ and my sales person, Eric, were great to work with and offered a ton of details before I approved the work. Great value and great cost. Interviewed 3 companies before choosing Abacus.
It also helps they have an affiliation and program with Home Depot.

We live in Austin, Tx. We have 2 a/c units for our 2-story house. In 2023, we chose Abacus to replace our old a/c. I assumed that since they advertised on TV, their cost would be higher than everyone else. They were the most responsibly priced bid out of the 5 we got. The system put in was a better unit than what others quoted. In April of 2024, our downstairs a/c stopped. I was praying we wouldn't need a replacement. Due to our exceptional treatment in 2023, we called Abacus. Joshua Bronstad showed up on time. He was able to troubleshoot the unit and had it running within the hour. No replacement is required at this time. It's an old system so I know it will need to be replaced in the future. Just grateful it was a small thing and we're back to our downstairs working again. I've dealt with bad companies in the Austin area. It's good to know that Abacus stands behind their work. I saw negative reviews on plumbing. The only thing I can suggest is if someone does crappy work that you aren't satisfied with, call the home office. A different a/c company tried to screw me over and I called their home office. I emailed them photos. They refunded my fee. I filed a complaint with the TX licensing board about the repairman. Find a company that stands behind their work and will send out a new repairman to get the job done. For now, I trust Abacus.

Extremely poor customer service. Abacus originally came out to do what they considered a 1 day electrical job. The job ended up taking longer than they expected b/c one of the electrician had only been on the job for 2 weeks. (At least this is what they told us.) Anyway they said they would be out the following day to finish up the job. Waited around the house the entire day the next day and they were total no shows. Finally called them directly early that afternoon only to find out they were not coming in as they had other scheduled jobs that day that they needed to see to. They then told us they could not come out the next day either b/c they had those scheduled jobs that they need to do. However, they would be there Friday morning to finish the job. Waited until 9:30 a.m. on Friday and still received no call (even though the night before we received a text message that they would be coming) so I called them. The dispatch lady said they were NOT coming now. Also, she mentioned that she had tried to call me. We received no missed calls on any of our phones btw. Her excuse was that some technicians had called in that they would not be working on Friday. She then said but you aren't the only client who had to be rescheduled. Evidently they had to reschedule their Friday clients. Well, I am a Tuesday client technically. I should have received priority based on how long I have been waiting.

Back in Dec. of 2023 I was on a river cruise with the guy that started Abacus in Houston but no longer owns the company. He does consult with Abacus in Austin he said. He basically said such good things about the company that is why I decided in the first place to even use them. Well, this company is no better than any other company out there. Very frustrating. Beware when booking.

Got my two HVAC systems replaced at my house with new Lennox SEER28 systems...very happy with the quick and quality installation.

However, the technician who inspected my old system, since i had hopes of repairing the old R22 refrigerant based systems first....he unfortunately lied and said certain aspects of the repair would be illegal, which i later found out is not true. He did correctly state that fixing the leaky system with the back stocked R22 would be exorbitantly expensive. But nothing ""illegal"" about the repair of an old R22 system, so i'm pissed about that.

Love the new AC systems and the installation. Hate being lied to about legality of repairing the old AC though!

I wanted to change out my double shower head/handle trim in my master bath to a different hardware. Tim with Abacus came out right on time and had them replaced within the hour. He was very professional and did a great job!

A plumber from Abacus came to our house to install a new garbage disposal and after they left it started leaking. I called and scheduled them to come out and fix it and scheduled for them to come out from 2-8 that day (which was a Friday). They said someone would call 30-45 minutes before coming and that was it. A couple hours later someone called and said we needed to call or text them back to confirm them coming (which, by the way, nobody said we'd have to do) so I texted back. They never responded to the text, so I called the number they left and got a message that said, ""No one is available to answer your call at this time."" So I called the number I called to do the original scheduling and they said they had rescheduled us to Monday because nobody called them back (even though they said I could call or text and did both). They tried to connect me to dispatch, but I got the same message that no one was available to answer, so I called again to see what they could do to help and the lady I talked to basically said it was my fault for not answering my phone (and didn't seem to believe me that I texted back, even though I had a screen shot of it) and there was nothing they could do- there was nobody they could send out and I'd just have to wait until Monday. So they basically messed up my sink and then made me wait an entire weekend to do anything about it. Save yourself a major headache and stay away from this company!!!
