Atlas Heat Pumps designs and installs Mitsubishi cold-climate heat pump systems for homes in Ithaca, Tompkins County, and nearby Finger Lakes communities. We are a Mitsubishi Preferred Diamond Contractor and a NYS Clean Heat participating contractor.
Every cold-climate heat pump we install provides both heating and air conditioning. We design each system around the home instead of relying on a one-size-fits-all equipment package. That means checking the heating load, layout, existing ductwork, electrical capacity, equipment location, refrigerant-line route, drainage, and rebate requirements before recommending a system.


A heat pump installer should do more than select equipment from a square-footage chart. The system must be sized for the home’s heating load and selected for its capacity during an Ithaca winter. The quality of the piping, electrical protection, drainage, testing, and startup work also affects comfort, efficiency, reliability, and equipment life.Atlas specializes in Mitsubishi heat pumps. We install complete systems and provide ongoing service for the systems we install. During your free in-home estimate, we explain the available designs, show you preliminary pricing, and identify the details that will determine your final installed cost.
Atlas installs several types of Mitsubishi heat pump systems. The right choice depends on your home, your existing heating system, and how you want the finished installation to look.

A ducted heat pump can often replace a forced-air oil, propane, or natural gas furnace. It provides central heating and air-conditioning through ductwork. We evaluate the existing ducts before determining whether they can be reused or need changes.

Ductless systems deliver heating and cooling directly to individual rooms or zones. Indoor units can be mounted high on a wall, close to the floor, or recessed into a ceiling. A ductless design can be a good fit for homes without usable ductwork or for rooms that need independent temperature control.

Many Ithaca homes are best served by a combination of equipment. One part of the house may use a ducted air handler with existing ductwork while another uses wall-mounted, floor-mounted, or ceiling-recessed units. Mitsubishi systems allow us to design around the home instead of forcing every room into the same solution. This install in Cayuga Heights had steam radiators and a finished basement. So we ran ductwork to a new air handler in the attic for the second floor and then installed a combination of low-wall and high-wall heads on the first floor since ductwork was not a viable option due to the finished basement. All those indoor units are tied to this single outdoor unit.

Mitsubishi intelli-HEAT can add heat-pump heating and air conditioning to a compatible existing furnace. This may be appropriate when a homeowner wants to reduce fossil-fuel use while retaining the furnace as part of the system. Compatibility and rebate eligibility must be confirmed for each home.
