I had 2 hvac systems installed on 12/8/23. Within 24 hours, one system stopped working due to "poor airflow." it was resolved, then on 2/1/24 (approx. 1.5 months later, the same system is now down - awaiting a technician). How is this possible? Total of 5 people (including installation, and 2 troubleshooting calls later), it is not working again. It hasn't even been 2 full months. Update: 2/2/24. Technician + Manager came out to troubleshoot, the issue was given high priority, and issue has been resolved. Although I was frustrated with the issue, Prof. Gatsby did resolve it by giving the issue high priority and appropriate level of attention. Was already signed up for long term maintenance package with them, will continue to do business with them. Update: 2/19. The Unit is non-functioning again (mere 17 days later - since last review). Quite frustrated with Professor Gatsby, and experiencing proper buyers remorse. On average, every 3 weeks, I have had to have a service call with professor Gatsby on a unit installed in Dec' 23. Very disappointed and frustrated. Would not recommend again.

Frequently Asked Questions

If you think about it, you really won’t know if you chose the right contractor for the job until its been installed. That’s why you want to make sure they have a money back guarantee and guarantee your satisfaction 100%, like we do.

When we come out to perform your estimate, we will identify what you have now, what your home should have and what’s important to you to help you make an informed decision on the level of efficiency that you’re looking for. If you won’t be in the home a long time, it may not be necessary for you to invest in the most efficient system. We can inform you about current rebates and 0% financing and at what efficiency level you can get them during your free estimate.

There are many things to consider when deciding to replace or repair.

Have you had a thorough diagnosis from a reputable company?

It’s important to be educated on what’s wrong with your system to make the best decision for your home

Are you having frequent repairs on your system?

As systems age, like your car, will cost you more and more up until the point of complete failure, often times at the most inconvenient time, like the dead of winter
replacing your system before these continued repairs will save you money and also keep your family comfortable.

Are you noticing that your utility bills are high?


Did you know that up to 70% of your home’s energy usage is correlated to your furnace, ac & water heater?

Many people don’t know how inefficient their system is or how much they can save with higher efficiency equipment. Studies have show, there is a tipping point, often around 15 years that says the level of efficiency drops from the advertised efficiency so your older system could be costing you more than it would be to just replace and then not have worries of large repairs.

Is your current system out of manufacturer warranty?


Operating an older heating system that’s out of warranty leaves you exposed when there is a major failure. Often times parts aren’t available.

Is your system obsolete?

The cost of repairs can be put towards a new system for more years of comfort

We find that when getting multiple estimates, no estimate is created equally. That’s why we spend time explaining to you exactly what your home should have, present you with options and leave with you a detailed proposal explaining everything you will be getting with us. We guarantee you pass your township inspection and perform heat load calculations to ensure that your home is being heated and cooled with the proper sized equipment.

The first step is to get you set up with a free estimate. Our technicians will come to your home, measure your home and equipment, determine what’s best, present your options and spend as much time as needed with you to ensure you’re 100% comfortable with us. We’ve been told we’re the most knowledgeable and thorough, when compared to our competitors. If you choose us, we will provide you with an installation date, start your permit and start working on the office portion of your project. We even call you the night before as a courtesy reminder! We send enough experienced technicians to your home to complete your installation in only 1 day, in 95% of our installations.

In most cases, our installations take 1 day. We send enough experienced technicians so we are able to complete that day. Our priority is to make sure you aren’t without heating or cooling.

We are proud to work with the local utilities like PSE&G, South Jersey Gas & Atlantic City Electric. They have programs that offer applicable rebates & 0% financing. In addition to these, we work with several other banks. Each of these has their own credit approval criteria, which our technicians will happily educate you on.

Not necessarily. This really depends on the age and condition of your equipment. Older systems use older refrigerants and can have different size equipment. Due to compatibility with these components, you may need to change both. We generally recommend replacing it together to save money if the equipment is older, but our technicians can help you decide what makes the most sense for your home.

We find that often times, a home’s existing heating and cooling system is the right size. How we make sure we get it right is by performing ACCA approved heat load calculations. If you have other estimates, ask the contractor what the load calculation says the home calls for. Our guarantees protect you from needing to worry about this but it is part of our process to ensure quality installations.
