Called on a Saturday, around 3:45 p.m. I was informed that if technician shows after 6 p.m., there would be a $150 service fee. I agreed, thinking it was reasonable if the quote wasn't outrageous and he could fix it that day given that they have a 24hr service. At 5:58 p.m., technician called to say that he was available. Imagine that. It took all of 45 seconds to explain that I had a small puncture in a plumbing pipe and he went back to his van to go ""work up the options"". He came back with a quote north of $2,100 and wouldn't be able to get to it before the next day (at the earliest). The price is outrageous. My usual plumber could get to it on Monday (at a cost of around $400), 24hrs after Abacus, but at cost that is less than 25% of their absurd quote. I laughed at the quote, telling him no and he replied (laughing), ""Yeah, I didn't think so either. Paying more than $2,100 is expensive"". It's pretty clear he wasn't planning to come prior to 6:00 as to make an easy $150 to simply present a quote. I'm chalking up the wasted money as a ""stupid tax"". I won't make the same mistake twice.

Great experience! Thank you Abacus for accommodating my hectic schedule and thank you Javier for coming out on a Sunday.

DO NOT USE ABACUS!
I had Abacus come out and look at my AC Condenser and they recommended to replace. Abacus quoted $5700 to replace, and i was able to get it done for $3200 with a higher quality unit than they quoted.

Had a failure in a Lennox AC evaporator coil still under warranty (W
which has been the subject of a settled class action law suit). The system worked fine until this coil failed but apparently Lennox coins of this era always fail. These guys told me I needed an entirely new AC unit and furnace, quoting 7,000 and 9,000 USD depending on which system I got. They never told me about the warranty issue (and keep in mind that this is a Lennox dealer). Second and third opinions from other companies was simply install a warranty replacement coil, total cost for labor under 900 USD. So be very careful dealing with Abacus. They will try to upsell you egregiously.

My AC was not blowing cool air and making a horrible noise in the attic. Contacted Abacus and they sent a technician out the very next day. The tech was on time, professional and efficient in the troubleshooting. He had identified the issue to a bad motor, cage and capacitor within the unit.
He came back with the itemized list of needed repair parts, and since my unit is over 14 years old, ""they are hard to come by"" totaling 2k (without labor). My other option was a brand-new system for 6K or 12K.
I thanked him and paid the service fee, took his itemized list and searched the internet.
I found all the parts including a contactor that was not part of the original quote for less than $400.00
I immediacy called there office and terminated any service agreement with them.

Terrible service. Only the owner is genuine, however if you look, they have many commercials (Print Ads, TV, and Radio; like on 106.9 ""The Eagle"" with Dean & Rog). How can they afford these advertisements? Because they charge like 5 or even 20 times what the repair should cost! Their service technicians are SALESMEN! Pure and simple. Most, not all, are very rude and patronizing. They will treat you as if you're very ignorant. Fortunately for me, I am a discerning consumer, and can spot a scam a mile away. It's all a scam. Buyer beware! Their shiny 150 vehicle fleet is a dead give away. Their nice uniforms would have you believe they're strictly professionals; they are not. Alan O'Neill is a very nice guy (owner), but his crews are ruining his business. They wanted, at one point, $50,000 to replace my air conditioner, then $18,000 to just repair it! Then I got a reputable company to replace it for 66 times lower than (or 0.015% of) Abacus' price! Abacus also did a lot of damage in their evaluation, which forced me to seek dry wall repairs and a painter (more money). Their top level technician, a Supervisor, talked down to my wife and I on more than one occasion. At one point, he admonished me! All of this is criminal.

kind of stupid but was looking for plumbing service, kept seeing their advertisement everywhere. good thing i came here to read the reviews. anyways on website it says REAL LIVE PERSON. im like great, so i start chatting and what do i get? Clair the bot. in which the same copy paste text it used was repetitive which is evident that its a bot. I called ""clair"" out and the bot kept saying its real but kept using copy paste to respond. if they are already LYING on their home page what more can they lie about. sure enough yelp reviews show they gouge price. i'll pass, the initial contact irritated me.

Mario came out for an electrical quote, he was very nice and answered my questions.

The quote was INSANE! $13,500 to add an additional box on my home (I was out of empty slots), 200ft of copper wire connected to a small box in my shed. Another $3,3500 to trench the 200ft! 2nd quote I received from another installer was $4,500.

Highway robbery.

My AC went out and I had called several companies trying to get a same day visit because it was really hot and my self and my 5 year old were home. They were the first to have an appointment for that day. $50 call charge was fine. My husband knew exactly what was wrong with it so we figured it wouldn't be too bad. The guy didn't even verify if our AC was under warranty before quoting us. Husband told him the AC was barely 3 years old so he quoted us again. Came back a few minutes later says oh the price went down a little then when we went to pay him the price went down a few more dollars. I feel like they play a guessing game on what they will charge to see how much someone is willing to pay. Won't use them again

Crazy Expensive! They were very responsive and friendly, but their quote for a very simple 30 min job was 3x more expensive than several other quotes. I was so shocked that I thought he had to have made an error. Nope, they are just expensive.
