If you’re a business owner, you know there are many moving parts to managing and operating a business successfully. While troubleshooting employees and running payroll are likely at the top of your mind, there’s another system that is often taken for granted until it goes down: your HVAC.
Commercial HVAC systems keep your employees cool when it’s hot outside and warm when it’s cold. But that’s just the start. They also keep your energy costs down and your customers comfortable when they visit your business.
If you’re in the market for a new HVAC system or thinking about upgrading your current system, there are some things you should know first.
What Is Commercial HVAC?
HVAC stands for heating, ventilation, and air conditioning. Commercial HVAC systems are different from residential units in that they’re sized differently, have larger capacities, and are overall more complex.
Commercial HVAC units keep larger areas like office buildings, retail spaces, warehouses, and industrial buildings comfortable for employees and customers. Commercial HVAC equipment helps regulate temperature and humidity levels as well as filters indoor air quality.
Think of how important an HVAC system is to your building like lungs to your body. An HVAC system pumps clean air into your building and removes stale air and contaminants from the air. Without proper ventilation and airflow, your business will feel uncomfortable and possibly even unhealthy or unwelcoming to employees and customers.
Here are just some of the reasons why you need a quality HVAC system for your business:
Keep employees & customers comfortable
We all know how distracting it can be when it’s too hot or too cold to concentrate. Not only does comfort affect your employees, but it also affects your customers. No one wants to shop at a store where it feels like the Sahara Desert!
The ideal indoor temperature for maximum productivity falls between 68-76 degrees Fahrenheit.
Improve indoor air quality
Did you know that indoor air can be just as dirty if not dirtier than the air outside? Here are some factors that can cause your indoor air quality to suffer:
- Inadequate ventilation
- Dust
- Allergens
- Chemicals
- Carbon monoxide
Luckily your HVAC system can help filter many of these pollutants out of the air.
Help control energy costs
Your HVAC system is responsible for up to 40% of your energy usage. A properly sized and efficient HVAC system can reduce your monthly operating costs.
Types of Commercial HVAC Systems
There are several different types of commercial HVAC systems. The most common types are split systems, packaged systems, variable refrigerant flow systems, and chiller systems.
Split Systems
Split-system air conditioners are the most common type of HVAC system. They use an indoor air handling unit and an outdoor condenser.
These systems are typically used in smaller commercial buildings like small retail stores or offices.
Packaged Systems
Packaged HVAC units have all their components contained in one cabinet. These systems are typically mounted on the roof of a building or on a concrete slab next to the building.
Packaged units are more compact and require less maintenance than split systems.
Variable Refrigerant Flow Systems
Variable refrigerant flow, or VRF HVAC systems, use refrigerant to cool and heat indoor air. These commercial units allow you to control the temperature in different areas or zones.
Var refrigerant flow systems are very energy-efficient and provide great flexibility for zoning.
Chiller Systems
Chillers aren’t cooling systems, but they do play a big role in cooling your building. A chiller system uses water as the cooling medium.
Commercial chiller systems are generally used in large buildings like hospitals, schools, and office buildings.
Commercial HVAC Components
Here’s a list of some common components that make up your HVAC system. It’s good to know these terms when speaking with HVAC technicians or contractors.
Thermostat
Your thermostat is how you control your indoor temperature. You can set your thermostat to maintain a certain temperature throughout the day or set a schedule.
Compressor
The compressor pumps refrigerant throughout the system and removes heat from the air.
Air handlers
Air handlers distribute conditioned air throughout your commercial space through the use of fans and filters.
Ductwork
Ducts are responsible for transporting air to different areas of your building. Leaky or improperly designed ducts can decrease your system’s efficiency.
Condenser
The condenser is responsible for expelling heat outside of your building.
Filters
Filters remove dust, pollen, and other airborne particles from the air. These should be cleaned or replaced regularly to keep your system running efficiently.
Maintenance Matters
One of the best ways you can keep your HVAC system running smoothly is by keeping up with maintenance. When your HVAC system goes without regular maintenance, you’re more likely to experience breakdowns and higher energy bills.
- Filters should be replaced or cleaned regularly.
- Have a professional tune up your system twice a year.
- Keep debris and dirt away from outdoor units.
When to Replace Your Commercial HVAC System
HVAC units don’t last forever. The average commercial HVAC system can last anywhere from 15-20 years. But like with most things, there are some signs you can look out for that may indicate your HVAC system needs replacing sooner.
Here’s a list of problems that indicate your system needs to be replaced:
- It requires frequent repairs
- Your monthly energy bills are increasing
- You experience hot or cold spots
- You hear strange noises like grinding, squealing, or rattling.
If your commercial HVAC system is pushing 15 years or is experiencing some of these issues, it’s a good idea to start thinking about upgrading to a new unit.
How to Choose the Right HVAC System
There are many things to consider when choosing a commercial HVAC system. One of the most important things you’ll need to do is properly size your equipment.
An oversized HVAC system will waste energy, and one that’s too small will struggle to keep your employees comfortable on bad weather days.
A professional HVAC contractor can help you determine the right size HVAC system for your building. They will take into account your square footage, ceiling height, windows, insulation, and more.
While cost will always be a factor when making purchasing decisions, you shouldn’t forget about the operating costs of an HVAC system.
Smart thermostats and sensors can help you improve your system’s efficiency by allowing you to program your thermostat and much more.
Smart HVAC technology can help you:
- Programmable thermostats
- Automatically adjust based on business hours
- Integrate with a building management system to maximize efficiency
- Monitor your system remotely and diagnose issues faster
- Reduce downtime
The environment is becoming more and more important to business owners. Not only does your customers care about your business’s impact on the environment, but it can also save you money in operating costs.
Since HVAC systems make up the majority of your energy budget, investing in an energy-efficient system can help you keep those costs low. Did you know that HVAC systems that use the refrigerant R-22 are being phased out?
Older HVAC systems should be replaced because they contain refrigerant that is bad for the environment. New HVAC systems use more energy-efficient refrigerants and components that help lower your emissions.
