Frequently Asked Questions

Yes! In almost all cases, we can be out to repair your system that same day! We are in the service business, so we do our absolute best to respond as quickly as possible to keep your family as comfortable, as quickly as possible.

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.

03/22/2023: updated review...as always Prof Gatsby's excels at what they do. Office team totally on top of maintenance checks and calls me to schedule to ensure I am on top of our maintenance. Easy schedule and awesome and sweet team. Had our AC maintenance check today and Jim was professional and knowledgeable and made recommendations to be more efficient. Love this team and this company! They outdo all other HVAC companies! I wish I could give 10 stars for this awesome company. We've been using Gatsby's for a few years now and the service from the office staff who call to remind us of upcoming service to schedule an appointment, to the techs who installed our HVAC and furnace systems and maintain, and to the owner who is so respected and honest, are AMAZING and professional. Truly the best in the business. THANK YOU.

Dominic was the best service person I think I have ever dealt with. If you guys send anybody but him, I will personally take it as disrespect! I love this company, I love the fact that it’s a small business, but Dom really was the icing on the cake. He was respectful, forthcoming, honest, and even though I didn’t follow through with the service, he offered me some other products and services that might help me down the line. Can’t express my gratitude enough, thank you all.

Great work by these guys. They showed up early, started promptly and did an outstanding job. I was worried about them busting through the bricks to install an exhaust but they didn't f up the brick work and patched it up nice. I highly recommend the Professor.

All of the workers are incredibly polite, extremely clean - booties over their shoes, rugs to protect the floors, the team of skilled workers have a fantastic work ethic; even when facing complications they stayed until everything was perfect. I can’t recommended them enough - they have a new lifetime customer.
