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.

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

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.
