A heat pump is a hybrid creation: it provides both heating and cooling benefits. Heat pumps utilize the heat in outdoor air in order to heat your home, and provide customers with greater control over their fuel choices. By including a heat pump in your heating system, you have the option of electricity-fueled heating and cooling, in addition to gas furnace heat. Heat pumps are cost effective and extremely efficient—at 300% efficiency, you can’t go wrong! Plus, it allows you to heat your home in the winter and cool it in the summer using the same system.

We are proud to carry a full line of air conditioning products to satisfy all of your commercial cooling needs.

We will work with you to ensure you have the products and applications to fit your needs. We supply cooling services to both existing commercial buildings and new construction projects.

A thermostat is used to regulate the temperature of your home heating and cooling systems. As with all of our HVAC services, we offers sales, repair, and maintenance of thermostat units. Upgrading to a programmable thermostat can help increase your commercial building’s energy efficiency. Our technicians will work with you to determine which type of thermostat is compatible with your current HVAC system.

Ventilation and ductwork installation goes hand-in-hand with the installation of furnaces and air conditioning systems. We offer the design and installation of ductwork systems in residential and commercial structures on a case-by-case basis. We have our own sheet metal shop and warehouse, enabling us to customize our work to the customer and to stock most commonly used materials and equipment.

Air quality and ventilation are extremely important to a healthy living or working environment. We carry a selection of top quality heat recovery and ventilation systems. These units pass fresh, outside air through a heat exchanger and into your office, while the old, stale air is passed through the other side of the heat exchanger, transferring energy to the incoming air. This creates a continuous supply of fresh air, purposefully distributed throughout your home. The air can be passed through a highly efficient cleaner to ensure air quality.

Grassi Refrigeration is dedicated to meeting your business’s commercial cooling and refrigeration needs. We will work with you to determine what refrigeration units best match your needs and budget. We are committed to quality installation, repair, and maintenance of commercial refrigeration systems. Our technicians have the skills and experience to handle any application, routine repair, or emergency service.

Planned Service Agreements & Preventive Maintenance

Routine, preventive maintenance is essential to the proper function of air conditioning and heating equipment. Without regular maintenance, your commercial HVAC system may require extensive and costly repairs down the line.

Studies show with regular tune ups, a unit will maintain up to 95% of its original efficiency. For our customers, this means the cost of an annual tune-up is recovered in the amount your save on your monthly energy bills and reduced repair costs. With proper maintenance and service, your air conditioner will also do a better job of dehumidifying your home.
