Size

Residential HVAC customers are typically looking for smaller, maintenance-free HVAC systems that can be installed on a budget, but do not require the same level of technical skill to install. Commercial HVAC services, on the other hand, may need larger systems that require more knowledge and skill to install. On top of that, most commercial HVAC services do not require a residential installation permit.

Placement

Residential HVAC systems typically need to be installed near a patio or front door, near an air intake. Commercial HVAC services may need to install the system in a new construction project, or across a large office building. On larger commercial spaces, like malls and skyscrapers, most HVAC units are placed on the top of the building. This helps provide more spatial accommodations while also making it easier for future repairs and maintenance from technicians.

Compressor and System Size

Commercial rooftop cooling systems can range from 10 tons of cooling capacity to over 100 tons of cooling capacity. The size of the cooling system will affect both the cost and the performance of a rooftop cooling unit. Larger systems will use more energy, but require less maintenance and have a longer lifespan. Residential HVAC systems are typically limited to 10 tons, but the costs can vary widely depending on the brand and model you get for your property.

Complexity 

Some individuals will be able to install a rooftop cooling unit on their own, while others will require professional help. It all depends on the type of unit and your level of expertise. Typically, commercial HVAC systems are much more complex compared to residential systems. This is due to the size and needs of commercial spaces as opposed to residential spaces. No matter what kind of property you have, residential or commercial, we here at Howard Services always recommend hiring a top-rated HVAC contractor to help with your heating and AC services.
