When extreme weather hits, you might notice that your building isn’t as good at maintaining a comfortable interior temperature as it used to be. If this is the case, an upgrade to your HVAC system could be the answer.
Read on for a deep dive into the average cost of replacing a commercial HVAC system, the best way to go about it, and the benefits of doing so.
What is an HVAC system?
HVAC stands for heating, ventilation and air-conditioning. An HVAC system integrates both heating and cooling solutions to maintain a comfortable interior temperature in your commercial property – whatever the time of year.
Commercial HVAC systems also ventilate your building, keeping the air clean and reducing humidity.
What does it cost to replace an HVAC system?
The replacement of your industrial HVAC system could cost anywhere from £3,500 to £11,000; the installation of a brand new HVAC system (with ductwork) can cost anywhere between £5,000 and £30,000.
However, you’re only likely to install an entirely new HVAC system if your current system isn’t working or has become completely out of date. HVAC systems are composed of many individual pieces of equipment. It’s far likelier – and more cost effective – to replace the different parts of your HVAC system as needed.
An evaporative cooling system, for example, is one of the most energy efficient options for industrial HVAC systems – particularly in large buildings. It uses around 90% less energy than many traditional cooling solutions, and is proven to improve the internal air quality of a building – reducing the spread of viruses.
Different parts of an HVAC system
These are the main components that make up a commercial HVAC system and might need replacing to increase your system’s performance.
Indoor unit
This is the unit that absorbs and cools heat inside your commercial building. It consists of a furnace, evaporator coil, and air blower.
Outdoor unit
This unit removes heat from inside your building. It consists of a condenser coil, compressor and fan.
Thermostat
The thermostat communicates with your entire HVAC system, telling it what temperature you want your building to be and adjusting the system accordingly.
Ductwork
Air ducts connect to the vents in your HVAC system, circulating air throughout your entire building. Ductwork is one of the most expensive parts of an HVAC system to replace.
HVAC replacement benefits
There are many benefits to replacing your HVAC system, including:
- Increased efficiency: Your system won’t take as long to reach your desired temperature.
- Energy saving: A more modern, efficient system also means less spent on your energy bills every month.
- Cheaper and easier to maintain: Whilst regular maintenance ensures the longevity of your HVAC system, a newer system will need far less expensive repairs to keep running at optimum levels.
- Quieter performance: One of the signs your HVAC unit needs replacing is if it’s making loud noises. A new unit will offer a quieter performance.
