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. If you just need a second opinion to make sure this is the best solution for you, we can help. If you’ve decided replacement is best, we can offer you a free estimate.

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 overpaying for Utilities?

Your older heating and air conditioning system is no longer operating at it’s manufactured efficiency rating. This combined with the newer, higher efficiency systems available today, the rising cost of electric and gas makes replacing now an easy decision. Today’s systems are also safer and provide much more comfort, due to technology that wasn’t available previously. Did you know there are electric and gas rebates and financing available to replace your system and save? Click Here to learn about programs in your area.

Generally speaking, if your system isn’t working currently, you would need a repair or a service call. If everything is operating, you would most likely just need some routine maintenance / tune-up. Here’s what a tune-up includes

Honest. Professional. Reasonable. Fantastic customer service. Matt and his team go above and beyond to make their customers happy. Even though I was out of warranty on my heater, Matt made sure I was fixed right and "covered everything". I've recommended him to friends and I know they've also been extremely happy. I tell anyone interested in repairs or a new system to call the Professor ☺ Tony 6/16/23 - I've used Professor Gatsby's for a new heater, new AC system and multiple repairs. Matt and his crew are just the best.

I reached out to perform a routine AC maintenance. After the work, the service technician wanted to review information with me. Of course at this point you’re thinking… here comes the upsell. Ryan mentioned that he noticed there was not a wet switch installed. He educated me on why that is important. Considering that I already had 2 leaks in the past because the units are all on the second floor, I was appreciative. I bit annoyed that no one, including the people who installed the new units never put one on. I would recommend this company.

Somehow my HVAC unit was pumping out heat in the summer making my home feel like a sauna. A quick call to Professor Gatsby, and they had someone out the very next day!! The tech was on time, professional and explained the entire process as he repaired the system. About 40 minutes later the system was fixed and cool air started to blast through the vents. We couldn’t be more thankful for the expedited response and service. I highly recommend Professor Gatsby for all your HVAC needs.

Quality and Cost Effective Installation, Replacement, and Maintenance Services for Air Conditioning

Everyone desires a cozy living space, especially when they are at home and want to unwind. Thanks to modern technology, it is now simpler than ever to maintain a suitable indoor temperature, regardless of the outside weather. During the sweltering Jersey summer, you may stay comfortable and fresh in air-conditioned interior places. Modern air conditioning will go a long way toward improving air quality, keeping you comfortable during the hot months, and your general health.

Some of our clientele are from towns like Washington Township, Sewell, Turnersville, Glassboro, Clayton, and Williamstown, among others, in southern New Jersey. Never hesitate to give us a call if you require reliable and trustworthy HVAC services.

Air Conditioner Installation

Installing air conditioners is challenging, so it’s crucial to seek the help of an experienced professional. Poor installation may result in an air conditioner’s effectiveness degrading over time and a lower lifespan. Our skilled technicians will fully install it following the manufacturer’s instructions. As a result, your air conditioner will last longer and maintain its warranty.

Air Conditioner Replacement or Relocation

Compared to a direct air conditioner installation, air conditioner replacement or relocation can be a little trickier.

Our team performs air conditioner replacements. We do it by removing the old units, cleaning the installation area, installing brand-new weatherstripping and sealing, and installing the new units. Our team can also suggest different air conditioning equipment depending on your demands.

In air conditioner relocation, we made sure to handle units with caution because it can harm them. The old air conditioner is painstakingly taken out of its existing site, packed safely for transportation, and then expertly reinstalled at a new location without any harm.

If you need a dependable expert to handle replacement or relocation, we are here to help. During the service, our experienced technicians pay strict attention to detail and have expertise working with numerous brands. We will ensure you get a quality service that will satisfy your HVAC needs.

Air Conditioner Repair, Trouble Shooting, and Maintenance

Air conditioners require routine maintenance, troubleshooting, and repairs. We provide expert AC repair services and yearly or seasonal AC maintenance, depending on your needs. With the help of our expert service, you can keep the device operating at its best. Contact our professionals if you have any problems or if the appliance stops functioning in the middle of the summer. Our team will respond swiftly and start solving the problem right away. We will carefully inspect the unit to determine the problem and provide honest, straightforward advice on any required repairs or maintenance.
