AIR CONDITIONING

Original Donnelly installs and services Carrier and Mitsubishi air conditioners and heat pumps. Paired with a gas furnace, they offer energy-use options and extra heating options. This combination, known as Hybrid Heat, is a high-efficiency, dual fuel system.

We offer traditional air conditioning systems, as well as ductless systems for homes without ducts. You can cool one room at a constant, comfortable temperature, as opposed to cooling the whole house.

All of our work carries a one full year warranty and has our exclusive NO-RISK GUARANTEE. If one year after installation there is not 100% SATISFACTION, we will remove the equipment and refund your full purchase amount. Time tested craftsmanship and customer service are our trademark. We maintain the highest standards of honest, dependable service.

• Comfort for you and your family
• Lower utility bills
• Quieter operation

Preventative Maintenance

80% of all emergency service calls can be avoided by regular preventative maintenance. Today's high efficiency air conditioners require a precision tune-up to keep them running at peak efficiency.

• Add years to the life of your cooling system
• Improve dependability - a well maintained system experiences far fewer problems
• Provide you with peace of mind - your air conditioner will work properly when you need it most.
