Professional HVAC Installations
Our team is highly experienced in the technical side of heating, ventilation, and air conditioning (HVAC). Any HVAC system installation we recommend is informed by decades of industry experience, and always tailored to your space, how it’s used, and your goals.
All commercial air conditioning systems we design, whether for heating or cooling, are chosen to meet the performance and aesthetic requirements of your premises. This way, your indoor spaces are closely controlled for humidity, temperature, and air quality.
If your business premises house manufacturing processes, stock storage, or welcome members of the public, a modern HVAC solution can be essential to the success of your operation.

How HVAC works and the types of HVAC systems
Commercial HVAC systems often use a combination of heating and cooling technology, along with an air movement system to control an indoor climate. For instance, vents and ducts that transport air between the outside and inside environments. Expert engineers and technicians can design HVAC systems according to specific applications for maximum energy efficiency and effectiveness.
Examples of common HVAC system types include:
Split system - separate components for heating and cooling with a central control.
Hybrid split system - utilises two different heating power sources, typically gas and electric.
Packaged system - heating and cooling components housed together in a single unit.
Ductless system - heating or cooling that functions without using air ducts.
Zoned system - individual HVAC systems for separate areas or rooms.

Before any work begins on an installation for a new commercial HVAC system, we conduct a thorough site survey. This is essential so our team can record the size and layout of your premises, both of which are factored into our design and installation approach.
This auditing process also analyses air flow throughout key spaces to identify risks and any areas that might require targeted solutions, such as extraction hoods to remove chemical fumes. If you are unsure whether or not your current system needs upgrading, we can offer unique insights.







Our Heating Solutions
Every business, no matter how big or small, has heating needs. At OKEL, we make sure your premises are comfortable while minimising energy consumption. Our systems will also help protect sensitive equipment and machinery.
Warm Air Heating

If you require quick heating that can maintain optimal temperatures with minimal energy consumption, warm air heating could be your best option. We can supply warm air heater models for all sizes and complexities of commercial premises, ranging from 10 kW up to 150 kW.
Our warm air solutions are available as either electric or gas warm air heaters, with the OKEL team providing tailored recommendations.
Electric Air Heaters

Improve comfort in your commercial space and help your business become more eco-friendly with an electric fuel heater. These gas-alternative systems are ideal for heating large spaces, with the versatility to be effective in smaller buildings as well.
At OKEL, we are experienced in designing and installing electric warm air heating systems for commercial premises. We will provide a long-lasting bespoke electric solution, whether you need to supply a factory, warehouse, sports hall, or office space.
FAR Infared

These systems provide spot heating to directly warm objects and surfaces in their path, including people. Our FAR infrared heating systems allow for straightforward zoning within commercial premises to further increase energy savings.
Infrared heating systems are often most efficient in spaces with varying footfall, such as restaurants, warehouses, exercise studios, and religious buildings. Here, ceiling or high wall mountings help save valuable space.
Radiant Tubes

Benefit from an even and consistent heat distribution with radiant tube heating. The result is greater comfort for staff and guests, as well as greater energy efficiency for your commercial spaces.
Our radiant tube heaters range from 10kW to 100kW, with capacity depending on the size of your premises and any unique aspects of your operation. We conduct thorough site surveys to determine your optimal heating requirements.




Air Conditioning for Commercial Spaces
Controlling temperature is vital for all kinds of businesses, from warehouses and industrial manufacturers to care homes and retail showrooms. We are experienced at installing bespoke cooling solutions in all kinds of commercial settings.
Evaporative Cooling & Ventilation Systems

Evaporative cooling is an energy-efficient and environmentally friendly way to cool large commercial spaces. By using water to naturally cool incoming air, these systems provide a constant supply of fresh air while significantly reducing energy consumption. Ideal for warehouses, factories, and other large open-plan buildings, evaporative cooling delivers cost-effective comfort and improved indoor air quality.
Air Conditioning Solutions

Regardless of how large or small your commercial properties are, we have the right air conditioning units for you. Take care of your team and equipment with consistent temperature control from OKEL. This includes Variable Refrigerant Flow (VRF), split, ducted, and wall-mounted air conditioning systems, so areas within your space are temperature-controlled for maximum safety and efficiency.
Destratification Systems
Powerful fans circulate air throughout large spaces to ensure even heat distribution. By automatically monitoring indoor environments, these fans switch on and off as required to conserve energy and provide a consistent temperature. Destratification systems can be paired with warm air heaters for a complete temperature control solution.

Frequently Asked Questions
- Will a heat pump work in cold weather?
Yes. Although heat pumps will be more effective in warmer climates, they can still provide warmth in colder weather. When sized and installed correctly, heat pumps from leading manufacturers function all year round.
- Can your HVAC systems provide heating and cooling?
Yes. Air conditioning is often associated with cooling spaces. However, these systems can provide efficient heating as well. If your space requires high air quality alongside air temperature control, a professional HVAC system could be the best option.
- Do your HVAC systems comply with health and safety requirements?
Yes. All heating, ventilation, and cooling solutions we provide are tested to ensure they comply with all relevant health and safety regulations and best practices for your business.
- How do I know if I need an HVAC system?
Certain kinds of business premises will need effective ventilation infrastructure to support key operations and protect staff and visitors. For instance, chemical manufacturing plants need powerful air movement systems to remove harmful gases from the environment. Any business which requires people to be inside for long periods of time can benefit from an HVAC system to improve the quality of the air.
- How to tell if my HVAC system needs updating?
If your existing HVAC system isn’t performing as it should, this can mean uneven temperatures within rooms, higher than expected energy bills, loud noises, and more frequent breakdowns. Even if you don’t notice any of these things, it can be worth checking your system if it’s old, to ensure it still meets the demands of your space.
