Exploring Different Types of Rooftop HVAC Units

Different Types of Rooftop HVAC Units

In Canada, where climate conditions can vary drastically, maintaining a comfortable environment in commercial spaces is crucial. Rooftop HVAC units are a popular choice due to their efficiency, space-saving design, and ease of maintenance. These systems are pivotal in providing year-round climate control for various commercial applications. As experts in commercial HVAC solutions, Roma Heating & Air Conditioning understands the importance of selecting the right rooftop unit to meet your business needs. In this article, we explore different types of rooftop HVAC systems, highlight popular brands and models in Canada, and discuss how Roma Heating can assist in optimizing your HVAC investments.

Types of Rooftop HVAC Units

1. Single-Packaged Units Single-packaged units contain all HVAC components in one compact box, making them easier to install and maintain. They are ideal for smaller commercial buildings or those with limited space for indoor HVAC components.

2. Split Systems Split systems feature components that are divided between an outdoor unit and an indoor unit, which can provide improved energy efficiency and quieter operation. These are suitable for larger commercial spaces that require flexible installation options.

3. Heat Pumps Heat pump systems are capable of both heating and cooling from the same unit, making them an economical choice for areas with moderate climates. They are particularly efficient in transferring heat rather than generating it through electrical input.

4. Gas/Electric Systems These units offer a combination of electric air conditioning and gas heating, providing a versatile solution for regions with a wide range of temperatures, typical of many Canadian environments.
