Commercial HVAC
Your Business Comfort Solution
At Donahue's Heating & Cooling, we understand that maintaining optimal temperature and air quality in commercial spaces is crucial for business success. Since 1962, we’ve been helping businesses across Greensburg, PA and surrounding areas create comfortable environments for their employees and customers. Our commercial HVAC expertise spans from small retail shops to massive industrial facilities, with our technicians trained to service everything from room air conditioners to 200-ton industrial chillers. Commercial HVAC systems differ significantly from residential units in scale, complexity, and operational demands. These systems must handle larger spaces, accommodate varying occupancy levels throughout the day, and meet specific industry regulations. We specialize in both servicing and installing state of the art comfort systems that address these unique commercial challenges, ensuring your business maintains the perfect climate year-round.

Types of Commercial HVAC Systems We Service
Our extensive experience covers all major commercial HVAC configurations. Packaged rooftop units (RTUs) remain the most common choice for many businesses, offering efficient heating and cooling from a single unit positioned on the building’s roof. These systems typically range from 3 to 50 tons of cooling capacity and can be configured with various heating options including natural gas, electric resistance, or heat pump technology.
Split systems provide another popular option, particularly for businesses requiring zone control or dealing with space constraints. We install and maintain variable refrigerant flow (VRF) systems that allow precise temperature control in different areas of your building simultaneously. Chiller systems serve larger commercial applications, using chilled water to cool buildings efficiently. Our technicians are equally proficient with air-cooled and water-cooled chillers, understanding the intricate differences in efficiency, maintenance requirements, and operational costs.
Energy Efficiency and Cost Savings
Modern commercial HVAC technology offers substantial energy savings compared to systems installed just a decade ago. We help businesses upgrade to high-efficiency equipment that can reduce energy consumption by 20-40%. Variable speed drives on fans and compressors adjust output based on actual demand, eliminating the energy waste associated with constant-speed operation. Smart thermostats and building automation systems provide granular control over temperature settings, scheduling, and occupancy-based adjustments.
Heat pump technology has revolutionized commercial heating and cooling efficiency. Our team specializes in installing geothermal systems that leverage stable ground temperatures to achieve coefficients of performance exceeding 400%. These systems, while requiring higher initial investment, typically pay for themselves through energy savings within 5-7 years. We also install air-source heat pumps featuring advanced inverter technology that maintains efficiency even in extreme temperatures.
Maintenance Programs That Protect Your Investment
Regular maintenance extends equipment life, prevents costly breakdowns, and maintains peak efficiency. We offer comprehensive maintenance programs tailored to your specific equipment and operational needs. Our preventive maintenance visits include:
- Filter replacement and coil cleaning: Dirty filters and coils force systems to work harder, increasing energy consumption by up to 30%
- Electrical component inspection: Identifying worn contactors, loose connections, and capacitor degradation prevents unexpected failures
- Belt tension and alignment checks: Properly maintained drive components reduce energy waste and prevent premature bearing failure
- Control system calibration: Ensuring sensors and controllers operate accurately maintains comfort while minimizing energy use
Emergency Response and Reliability
When commercial HVAC systems fail, business operations suffer. Lost productivity, uncomfortable customers, and potential inventory damage demand immediate response. Our 24/7 emergency service ensures you’re never left without climate control when you need it most.
We understand different industries have unique HVAC requirements. Restaurants need powerful ventilation to manage kitchen heat and odors. Data centers require precise temperature and humidity control to protect sensitive equipment. Healthcare facilities must maintain specific air pressure relationships and filtration standards. Our comfort consultants design systems to specifically fit these specialized needs, ensuring compliance with industry regulations while optimizing comfort and efficiency.
