Alexander Services specializes in installing, maintaining, and repairing commercial HVAC systems for commercial buildings, multi-family units, restaurants, stores, and facilities and provides 24-hour service. For immediate service, call (919)796-4897

The following are a few services we provide for commercial clients.

  • Installation: We install heating, ventilation, and air conditioning systems in various commercial buildings such as offices, multi-family units, retail stores, hospitals, schools, industrial facilities, and more. This includes furnaces, boilers, air conditioning units, ventilation systems, ductwork, and related components.

  • Maintenance: Regular maintenance is crucial for keeping HVAC systems running efficiently and prolonging their lifespan. We offer maintenance services such as cleaning, inspecting, lubricating, and adjusting components to ensure optimal performance. We also offer preventative maintenance contracts where they schedule routine visits to check and maintain the system.

  • Repairs: When HVAC systems malfunction or break down, commercial HVAC companies are called upon to diagnose and repair the issue. This could involve fixing or replacing faulty components such as compressors, motors, thermostats, or refrigerant leaks. Prompt repair services are essential to minimize downtime and maintain comfort levels within the commercial space.

  • Upgrades and Retrofits: As technology advances and energy efficiency becomes increasingly important, we can help companies upgrade their existing systems or retrofit older systems with newer, more efficient equipment. This can include installing programmable thermostats, energy-efficient HVAC units, or implementing zoning systems to better control heating and cooling in different building areas.

  • Indoor Air Quality Solutions: Alexander Services offers services to improve indoor air quality within commercial spaces, including reducing the risk of the COVID-19 virus spreading. This could involve installing air purification systems, humidifiers, dehumidifiers, or ventilation upgrades to ensure occupants have clean and healthy air.

  • Consultation and Design: In addition to installation and maintenance, we often provide consultation for new construction projects or renovations. We can work with architects, engineers, and building owners to meet the specific needs and requirements of the commercial space, considering factors such as building size, occupancy, usage, and energy efficiency goals.

Alexander Services plays a critical role in ensuring that commercial buildings maintain comfortable temperatures, proper ventilation, and good indoor air quality for occupants while also helping businesses optimize energy efficiency and minimize operating costs.

What is the difference between a Residential and Commercial HVAC Service?

There is a difference in terms of scale, complexity, and requirements. Here are some of the main distinctions:

  • Size and Capacity: Commercial HVAC systems are typically larger and more powerful than residential systems. They must heat, cool, and ventilate larger spaces such as office buildings, retail stores, hospitals, or industrial facilities. Residential HVAC systems are designed for smaller spaces like single-family homes, apartments, or condominiums.

  • Complexity: Commercial HVAC systems are often more complex due to the size and layout of commercial buildings. They may involve multiple units, extensive ductwork, zoning systems, and more advanced controls to manage temperature and airflow in various areas of the building. Residential systems are generally simpler with a single unit or a smaller number of units serving the entire home.

  • Customization: Commercial HVAC systems often require customization to meet the specific needs and requirements of different types of commercial spaces. They may need to accommodate varying occupancy levels, specialized equipment, or specific environmental conditions. Residential systems are more standardized and typically have fewer customization options.

  • Regulations and Codes: Commercial buildings are subject to different building codes, regulations, and standards than residential buildings. The company must be licensed in commercial service. Commercial HVAC systems must comply with safety, ventilation, energy efficiency, and indoor air quality regulations. Residential HVAC systems also have regulatory requirements but may differ in scope and stringency.

  • Maintenance and Service: Commercial HVAC systems typically require more frequent maintenance and service due to their larger size and higher usage. Commercial HVAC companies often offer maintenance contracts and scheduled service visits to ensure optimal performance and minimize downtime. Residential HVAC systems also require regular maintenance, but maintenance tasks’ frequency and scope may differ.

  • Cost: Commercial HVAC systems are generally more expensive to install and maintain than residential systems due to their larger size, complexity, and customization requirements. The cost of commercial HVAC systems can vary significantly depending on building size, system capacity, equipment features, and installation complexity. Residential HVAC systems are typically more affordable upfront and have lower ongoing maintenance costs.


Overall, while commercial and residential HVAC systems serve the purpose of heating, cooling, and ventilating indoor spaces, they differ in size, complexity, customization, regulatory requirements, maintenance needs, and cost.
