What can you say about 3 main types of commercial HVAC systems?
Heat pump systems, which are used for either cooling or heat pumping. These are large multi-splits units that are more efficient for open spaces. Heat recovery systems, which can cool and heat buildings simultaneously. The systems save energy and are ideal for use in commercial spaces comprising of several rooms.
What are commercial AC units?
Commercial AC units usually combine the heating and cooling units in a single rooftop package, which prevents the noise it causes from interfering with occupants’ work. Keeping the package on the roof also helps the business conserve physical space.
How does HVAC work in commercial building?
The heating aspect of an HVAC system is produced by using radiators or supply air systems within the commercial building. Ventilation is accomplished by extracting contaminated air out of the building while maintaining clean air. It also circulates the internal air and removes any excess humidity.
How do you size a commercial HVAC system?
To determine the size of system you’ll need, divide the amount of Btu you need by 12,000. For example: 100,025 to 125,000 Btu is 8 to 10 tons. 125,025 to 150,000 Btu is 10 to 12 tons.
How many tons is 4000 square feet?
Simple answer: You need 0.0016 tons of AC per square foot. In general, for every 600 sq ft, you need 1 ton of AC. This is a general estimate.
How many BTUs do I need for a commercial building?
To achieve the base value of Btu Multiply the square footage by 25. Add 400 Btu for each occupant, and 1000 Btu for each window or door outside.
How many square feet can a 5 ton AC unit cool?
How many square feet does a 1 – 5 ton air conditioner cool?
| AC Unit Capacity (Ton) | Cooling Capacity Square Feet |
|---|---|
| 3 Ton | 1,400 – 1,600 sq ft |
| 3.5 Ton | 1,650 – 1,800 sq ft |
| 4 Ton | 1,850 – 2,100 sq ft |
| 5 Ton | 2,400 – 3,000 sq ft |

Several factors can affect precisely how often you schedule commercial maintenance, but a good rule to live by is to schedule a maintenance check-up twice a year. The best time for maintenance is during the spring and fall since systems endure the heaviest strain in the following seasons of temperature extremes.
Do commercial AC units have filters? In controlled indoor environments like offices, you can expect to change your filter at least three to four times a year. Commercial HVAC units operating in more difficult and unpredictable environments—such as medical or military buildings—will require more frequent air filter replacement.
What is HVAC system in commercial building?
Heating, Ventilation, and Cooling systems, otherwise known as HVAC systems, are an integral part of modern buildings. HVAC systems are in charge of keeping temperatures comfortable (usually around 72 degrees), humidity consistent (between 40-60%), and indoor air quality high (keeping C02 to less than 1000PPM).
How do you heat a commercial building?
Common commercial heating systems include furnaces and boilers. Furnaces provide heating with warm air and boilers provide heating with warm water. Furnaces and boilers can be categorized as either condensing or non-condensing.

What is the difference between commercial AC and residential AC?
The first major difference is the size. Residential HVAC units are much smaller compared to commercial systems. Commercial HVAC systems are larger because they are generally employed to cool much larger spaces. Spaces like warehouses, department stores, and even medium-size businesses benefit from these larger systems.
What are the requirements to consider in commercial airconditioning system?
Commercial air conditioners require special consideration for installation, repairs, and maintenance, as they have substantial differences from residential air conditioners. The key difference between cooling a commercial area and cooling a residential space is the amount of power required by the air conditioner.
What is commercial HVAC preventive maintenance?
