H-Mac Systems

H-Mac Systems was established in 2003 to serve as a reliable source for commercial/industrial HVAC equipment and parts. We started in a modest, windowless office with a handful of manufacturers and a strong desire to make a contribution to the Heating, Ventilating, and Air Conditioning industry. Today we are one of the country's leading e-commerce HVAC distributors, stocking thousands of name-brand products in our purpose-built office/warehouse facility located in Southborough, Massachusetts. Since the beginning in 2003, customer focus has driven everything we do.

Commercial and industrial gas heaters are a great choice for heating large, open spaces. They're economical, reliable, and more efficient than electric heaters. Whether you choose a natural gas heater or a propane gas heater, only the fan and control component require electricity to run-so you'll use far less electricity to heat your workshop, warehouse, conference space, or other facilities than you would use with an electric heater. Whether you go with a propane or natural gas heater will depend upon a variety of factors.

Commercial and industrial electric heaters are affordable and versatile, making them a go-to heating solution for many offices, warehouses, storage spaces, and more. They're reliable and typically safer than fuel-fired heaters, since there is no combustion process and no noxious fumes or combustible gases that may escape. Electric heaters are efficient-they retain that efficiency even as they age-and are especially affordable to operate if you live in an area with low utility costs. Furthermore, they're easy to install, and they come in a variety of styles to suit your application.

A good ventilation system is essential for good indoor air quality, and it's especially important in commercial and industrial settings where people may be working around chemicals, gases, and other particulates and contaminants. The right system helps prevent condensation and mold and lowers the risk of respiratory issues among your employees. When choosing your ventilation system, you have to consider whether you want to expel the indoor air, as you would with a roof fan, or if you need to exchange it with outdoor air, which can be done with energy recovery ventilators.

Having to interrupt your work and decrease your productivity for an electrical issue that's beyond your control is incredibly frustrating-not to mention costly. That's why commercial and industrial generators are so important within warehouses, offices, and other facilities. These organizations keep commercial generators on hand for backup in case of a power outage or other emergency. Some industries and job sites rely on them exclusively-a construction site doesn't always have access to electrical outlets, for example.

Appropriate heating is important for the safety and comfort of your employees as well as to protect your equipment, products, pipes, and more. The type of heating system you need will depend upon the size of the space, insulation and efficiency, your power source, and temperature variables, among other factors.

H-Mac Systems is one of the country's leading AC supply companies carrying thousands of the best air conditioning units from trusted brands like Amana, Koldwave, MovinCool, Port A Cool and more. Which cooling system is right for you? It will depend on what part of the country you live in, the size of your space, the temperature range you're trying to control, whether you need both heating and cooling or just cooling, and more.
