What People Say About Us
Professional and courteous!
They did an awesome job with precision and expertise!
Joe was the technician and he was great--super friendly and thorough. I've used other local companies and they were in and out in 20 minutes but not Joe. Joe was different and better--he flushed the system, hosed off the outside unit, tested the output temperatures and more and kept me updated along the way. Prior to the appointment I received text and email reminders. What was really impressive was that I received a text when Joe was on the way and it included his name, photo and a brief bio that included his hobbies--it took away the uneasiness of a "stranger" coming over. I don't remember who I spoke to on the phone to schedule the appointment but she was kind, professional and informative.
Update! I used Prof Gatsby again, this time to fix a dripping tub faucet and a bathroom sink that regularly clogged for no reason. Previous attempts by others to resolve the problems were unsuccessful. Bob, from Prof Gatsby arrived on time. He was super nice and great at explaining things. He provided options with zero pressure on me to make a fast decision. I decided what I wanted and let Bob work his magic. It's been a few weeks since the repairs and I could not be happier! Everything looks great and works great.
He quickly assessed the problem and repaired it and then went above and beyond to make sure to find the cause of the problem to try to prevent it from happening in the futuee.
He then came back later in the week to do an additional equipment replacement with Patrick.
Both were not only highly professional but also great customer service and attention to detail.
They don’t make the customer feel badly asking questions and it’s great to get the answers as a homeowner who doesn’t have the same knowledge.
Look no further than Professor Gatbsy’s. You will NOT be disappointed.
Would highly recommend

Professor Gatsby. They are the best.
I had a great experience with Professor Gatsby. Chris and his partner did a terrific job in installing the air conditioner. After the air conditioning installation was done, Chris fully explained what he did to me. He answered all the questions I had.
They took care of everything with help from TJ and another guy who came in to lend a hand.
Everything was done to perfection.
Steve made the deal easy to understand and took care of all the paperwork from ACE.
Thanks, Guys!
Kept me informed of what he was doing.
THEY are all so knowledgeable and professional . THEY actually do their job while making "customer service" a thing. thanks Sean
They were here when they said they would be.
They were very friendly and respectful. As we had new carpet put in and they respected our request to put shoe covers on when walking on the new carpet.
They took the time to show us all the work that was done and took the time to explain the system. Making sure we knew how to work the system and answering any questions that we had. They didn’t leave till they were 100% sure we had all our questions and concerns answered.
I would highly recommend them and would definitely use them in the future.
The installation was completed efficiently and with great attention to detail. Our Home is now more comfortable than ever, and we've already noticed an improvement in energy efficiency. It's clear they take pride in their work and truly care about customer satisfaction. John and Jose both were Professional and friendly.
We highly recommend PROFESSOR GATSBY'S to anyone looking for reliable high-quality HVAC SERVICE.
Thank you again

P.S. My daughter uses Professor Gatsby as well. They replaced her HVAC system and did some plumbing work for her.
We had gotten several quotes from reputable companies in the area. To be honest, the spread of prices was narrower than I expected. I will say that Professor Gatsby's was the highest initially, but we made some concessions on single vs dual stage blower etc and were able to reach a price that we were happy with. Especially since it included attic air-sealing and adding blown-in insulation.
Brandon Simpkins was very helpful in explaining all the work that would be done in detail as well as laying out our options. He also helped walk us through the process of applying for and getting all the rebates and financing for the project, and was able to get the installation of a whole-home humidifier included in the project scope as well. He was also very communicative, responding promptly to any questions/calls we had.
On install day, the crew from Professor Gatsby's showed up at 7:30AM as promised, ready to go. The install crew was at the house all day until almost 5PM and they were busy the entire time. I will say though, it is an extremely clean-looking installation. Even to the detail of the wire/pvc/gas routing you get the feeling that it was done to a high standard, and the space was clean as a whistle when they left. Jose, Jacob, and Lee were all communicative, friendly, detail-oriented, and you could tell they cared about the quality of the work. Jose, the head installer for the day, was especially communicative and kept me up to date about install progress, encouraging me to take a detailed look multiple times and ask questions so that I was fully comfortable with everything.
Now I am just waiting for the paperwork so that I can get the township to come out for the inspection for the final permit approval. To be honest, I don't expect them to find much of anything. And if they do, I am confident that Professor Gatsby will resolve it promptly and courteously.
Between the clear, detailed, and friendly communication, the flexibility on scope of work to adjust for pricing, and the quality of the install, I can only give praise so far. The equipment installed carries a strong warranty for labor and parts as well. Fingers crossed I won't have to use those warranties but they are invaluable to have for peace of mind.
knowledgeable. I would highly recommend to everyone who needs HVAC or plumbing work.
Ordinarily,the decision to replace them would have been one which required a lot of thought and consideration on our part.
But fortunately,the inspection was done by a serviceman from Professor Gatsby's.Thanks to a suggestion from a friend two years ago,we have used them for other inspections and services,and have been very pleased with their thoroughness and overall professionalism,at a reasonable cost.
The Gatsby team arrived at our house precisely at the arranged time(that in itself seems like a rarity with service people these days)
They went right to work. This was an especially challenging assignment,since our considerably sized heater was in the attic,with a very narrow entry point.So not only was it tricky to remove and bring down the old heater down the ladder,but of course the new one had to be brought up.
The crew worked diligently.
One of the things that really impressed us was that they showed a true sense of teamwork.
Well,after several hours,the work was done.Both the heater and AC unit were tested,and to say that we were pleased with the results would be an understatement!
The team also gave us a very thorough explanation of all the work that they had done,and answered all of the questions that we had for them.
If we had hired another company to have the work done,the results might have not been as satisying for us.
But the Professor Gatsby's team were superstars.Their hard work and professionalism brought us great satisfaction and we couldn't be happier with the results!
April '25 - compressor clean and a soft start installed. Excellent service from Dom D.
Problem solved!
EXCELLENT Based on 569 reviews Cindy Miller2024-09-11Trustindex verifies that the original source of the review is Google. They saved the day!! I had water everywhere and they were able to dispatch a technician to my house immediately! The technician was courteous, professional and really knew his stuff! Thank Professor Gatsby!! Grace Zuccarello2024-09-06Trustindex verifies that the original source of the review is Google. 2 gentlemen showed up to take a look at our water pressure and well pump. Unfortunately they were not able to preform any tests because the previous plumber had left shoddy work, and they didn’t want to risk it. They suggested a few names for us to call. Their fee ($225, I think) was not cheap to pay, but at least they were honest and didn’t cause us bigger issues.

Thank you! Matt Chimento2024-08-23Trustindex verifies that the original source of the review is Google. Steven Mays2024-08-23Trustindex verifies that the original source of the review is Google. My existing system had a failure. I called Gatsby, and they sent a technician to diagnose the issue. Unfortunately the parts were unavailable and backordered 3 months. I verified this myself by hunting down the parts and not being able to find them anywhere. After discussions with the service manager Fury, I asked to get a quote on a new system. I received quotes from other companies as well, to ensure I was getting a fair price. The salesman Steve gave me a quote that was a few thousand less then the competition, and after researching the Amana line of products I decided to go with Gatsby for a new system. Steve then went above and beyond by going back to the main office to get AC units so that my family would be comfortable until the new system could be installed. This was 5:30PM on a Friday - superb customer service. Kyle and his crew started at 7:30 and finished at 7:30. It was a long day. At the end, Kyle walked me through everything explained everything they did thoroughly. The technicians were clean and treated my home with care, and went above and beyond replacing a valve that supplied my humidifier. It is now day 2 with the new system and it is humming along. It's super quiet. After the install I texted Steve the salesman a few questions and received answers back promptly. I did a lot of research on the system and the Amana S Series with a heat pump is the real deal. It replaced my carrier infinity system and it is much quieter, performs at least as well, and was several thousand dollars less. Along with top notch customer service, clean install, 10 year parts and labor warranty - I really feel Gatsby went above and beyond in every way possible. Edward Knowles2024-08-21Trustindex verifies that the original source of the review is Google. Always send great and personable professionals to our home. Thanks again for another good experience. Thanks Joe! Ray Dudek2024-08-19Trustindex verifies that the original source of the review is Google. Sean M was extremely knowledgeable in all facets of the system. Explained precisely what he would do and what recommendations he suggested to ensure peak performance. Very friendly and clearly an experienced technician. I would highly recommend him for any heating or AC needs. I hope to see him again!
