About Us

While learning the trade, John Marrone imagined a better way to do business. As a result, he cultivated a vision to improve upon the status quo in the HVAC industry. He realized that many customers were not satisfied with the level of communication between themselves and the contractors that serviced their buildings and businesses. The cost of these breakdowns manifested itself in dollars, safety and stress. Marrone Mechanical sets out to create a new business model built on collaboration between the contractor and the client. The goal of Marrone Mechanical is to build a working relationship with the owner / operator of each site to anticipate HVAC service needs before they become HVAC emergencies. To catalogue the HVAC equipment in your building, to store parts for these particular machines so there is no down time waiting for orders during emergencies, to consult on new installations and products in order to engineer HVAC systems to be more sustainable and function more efficiently, these are just a few examples of the services that set Marrone Mechanical apart.

For many years now this collaborative method has produced outstanding results. Marrone Mechanical has successfully provided for the commercial HVAC needs of dozens of well known businesses in the city of Philadelphia and the surrounding region. Owner John Marrone, personally meets with each client to not only discover that client’s immediate mechanical needs but also to understand the customer’s vision for the future of their business. Mr. Marrone wants each client to understand that he is personally invested in the success of his or her building. In essence, each client has a relationship with Marrone Mechanical and that customer can be assured that Marrone Mechanical will be invested in the safe installation and production of the mechanical needs of their business. 

Prompt, professional, safe services are the ingredients that bond Marrone Mechanical with clients. Marrone Mechanical focuses on building these long term relationships with clients so they can focus on their own business. This model has been so successful that since its inception, no Marrone Mechanical client has left for another firm. “Our clients quickly realize that our model of conducting business is different. They call me, I visit them, we identify the issue and we fix the problem quickly, safely and professionally.” Think of Marrone Mechanical as a valuable extension of your own business, eagerly tending to building and maintenance HVAC needs that might otherwise distract you from the business at hand. We are merely an extension of your team allowing you to focus on what matters most to you – your business.
