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.

Upgrading to a programmable thermostat can help increase your home’s energy efficiency. Our technicians will work with you to determine which type of thermostat is compatible with your HVAC system.

Ventilation and ductwork installation go 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.

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 home, 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.

Adding a fireplace or freestanding stove into your home can increase its energy efficiency, as well as add value to your home. We carry a variety of gas, electric, and propane fireplaces and will help you find the perfect unit to match your home, style, budget, and heating needs. Grassi offers the largest selection of clean-burning, high-efficiency hearth products in Walla Walla.

An air filter plays a vital role in your home’s forced air HVAC system. The air filter cleans the air and removes bacteria and harmful particles. Improving your home’s filtration system is an important first step in improving indoor air quality. Regularly changing your filters also helps your air conditioner and furnace stay cleaner and operate more efficiently. Our pleated, MERV-rated filters are made using Kimberly-Clark cotton-poly blended media and are tested according to ASHRAE standards. Our air conditioning filters and furnace filters are made with heavy-duty beverage board frames to prevent airflow bypass.
