Heat Pumps
Understanding Heat Pump Technology for Your Home or Business
Heat pumps represent one of the most efficient heating and cooling solutions available today, and at Donahue's Heating & Cooling, we’ve been installing and servicing these versatile systems since our founding in 1962. Unlike traditional furnaces that burn fuel to create heat, heat pumps move existing heat from one place to another, making them incredibly energy-efficient. During winter months, they extract heat from outdoor air—even when temperatures drop below freezing—and transfer it inside your home. In summer, the process reverses, pulling heat from your indoor spaces and releasing it outside, functioning just like an air conditioner. The technology behind heat pumps has advanced significantly over the past decade. Modern units can maintain comfortable indoor temperatures even when outdoor temperatures plummet to -15°F, thanks to innovations in compressor technology and refrigerant formulations. Variable-speed compressors allow these systems to adjust their output based on your home’s heating or cooling demands, eliminating the constant on-off cycling that wastes energy in older systems. Our comfort consultants at Donahue's Heating & Cooling design systems specifically tailored to each customer’s needs, ensuring optimal performance whether you’re heating a small residential space or cooling a large commercial facility.

Energy Efficiency and Cost Savings
The efficiency of heat pumps is measured using two key metrics: SEER (Seasonal Energy Efficiency Ratio) for cooling and HSPF (Heating Seasonal Performance Factor) for heating. Today’s high-efficiency models achieve SEER ratings of 20 or higher and HSPF ratings exceeding 10, translating to substantial energy savings compared to conventional heating and cooling systems. For every unit of electricity consumed, a heat pump can move three to four units of heat energy, achieving efficiency rates of 300-400%. This remarkable efficiency means lower utility bills throughout the year, with many homeowners in Greensburg, PA and surrounding areas seeing reductions of 30-50% in their heating and cooling costs.
The financial benefits extend beyond monthly energy savings. Many utility companies offer rebates for installing high-efficiency heat pumps, and federal tax credits can cover up to 30% of installation costs for qualifying systems. Our team stays current with all available incentives and helps customers navigate the application process to maximize their savings. Additionally, because heat pumps provide both heating and cooling from a single system, you’ll save on maintenance costs compared to maintaining separate furnace and air conditioning units.
Types of Heat Pumps We Install and Service
We specialize in installing and servicing several types of heat pump systems, each suited to different applications and property types.
- Air-source heat pumps are the most common type, ideal for residential and light commercial applications throughout Greensburg, Latrobe, and Irwin, PA
- Geothermal heat pumps utilize stable ground temperatures for even greater efficiency, perfect for properties with adequate land space
- Ductless mini-split heat pumps provide targeted comfort for individual rooms or additions without existing ductwork
Each system type offers unique advantages. Air-source units require minimal installation disruption and work well with existing ductwork. Geothermal systems, while requiring more extensive installation, offer the highest efficiency ratings and lowest operating costs over their 25-50 year lifespan. Ductless systems provide precise temperature control for specific zones, making them perfect for home additions, converted garages, or buildings with hot and cold spots. Our technicians service everything from small residential units to large commercial systems, ensuring reliable operation year-round.
Professional Installation and Ongoing Maintenance
Proper installation is crucial for heat pump performance and longevity. Our highly trained technicians follow manufacturer specifications precisely, ensuring correct refrigerant charges, proper airflow, and optimal system configuration. We perform load calculations for every installation, determining the exact heating and cooling capacity needed for your space. This prevents the common problem of oversized or undersized equipment that leads to inefficiency, frequent cycling, and premature wear.
Regular maintenance keeps heat pumps operating at peak efficiency throughout their service life. Our comprehensive maintenance programs include cleaning coils, checking refrigerant levels, inspecting electrical connections, and verifying proper airflow. We recommend twice-yearly maintenance visits—once before cooling season and once before heating season—to catch potential issues early and maintain manufacturer warranties. With our 24/7 emergency service, we’re always available when unexpected problems arise, minimizing downtime and discomfort for both residential and commercial customers. Contact us today.
