Professional Quality HVAC Parts and Supplies


Prostock stores, the retail purchasing environment for heating & air conditioning contractors, is well organized with most products on display for easy access. The retail-like feel gives you a convenient way to locally shop and plan for HVAC parts, products and supplies.


May-Hy Distributors adopted the Prostock concept to enhance our offering to local heating and air conditioning contractors. Since opening our Prostock store we have received positive feedback from air conditioning contractors of how they have improved response time to their customers. And heating contractors have been able to stay ahead of the competition from their ability to economically and quickly repair air conditioners, gas furnaces and other HVAC equipment.


Prostock will enhance the Network Program later this year. The expanded version has capability to offset the effects of price fluctuations due to fuel costs. This is one example of the benefit of the Prostock program.


Prostock replacement parts department is committed to improving the business of our HVAC contractors by providing quality services, products and supplies that earn customer trust and build lifetime customer satisfaction. We value our contractors and will continue to demonstrate respect with integrity and positive energy.  Visit the Prostock store online. Contact us for your password for full access.


Our team at Mar-Hy Distributors would like to graciously thank you for your business.
