Rooftop units (RTUs) are the quiet, hidden heroes behind modern commercial buildings. In fact, did you know that these powerful appliances deliver heating and cooling to nearly 60% of commercial buildings in many areas across North America? If you’re wondering how to improve your building’s commercial HVAC in Edmonton, we’re here to help.
Below, let’s dive into some of Weiss-Johnson’s favourite tips and tricks for boosting your RTU’s efficiency.
Replace Filters Regularly
Even the highest-efficiency rooftop units can lag behind in power when their air filters are clogged. As a result, RTU filter replacements are one of the most important year-round commercial HVAC tasks in Edmonton.
The return air filter is typically located near the RTU’s top cabinet, right before the blower. Prioritize replacing this filter regularly to keep the unit performing well. Exact timelines vary by model, so check your manufacturer’s manual or consult a professional commercial HVAC technician in Edmonton.
Adjust Thermostat Scheduling
An efficient thermostat schedule makes a real, noticeable difference when it comes to energy usage and ongoing costs. As seasons change, make it a priority to double-check the thermostat to ensure it reflects the building’s needs. For example, an RTU set up on a school building may only need cooling during the summer while school is still in session.
Additionally, multi-unit RTU setups can be configured for different building zones, further enhancing customization. For instance, programmable controls are an easy retrofit on most existing RTU systems.
Keep Airflow Clear
When air moves freely, your rooftop unit can operate more efficiently with less strain. RTUs are exposed to the full force of all the elements on rooftops, so it’s important to check them regularly for blockages and debris.
During colder weather, check the condensing coil for weather damage or outdoor buildup, such as leaves. On commercial properties with heavy pigeon activity or near trees, watch for debris as it may accumulate faster than expected. For additional protection, bolt-on bird screens and animal guards can also be installed to keep out buildup.
Ask About Upgrades
A few strategic upgrades can sometimes be the difference between an RTU that lasts longer and one that falls behind building needs. For example, a smart thermostat can seamlessly be retrofitted into your current RTU setups. Once it’s set up, this data-driven upgrade can automatically adapt to schedules while monitoring overall performance.
Other common upgrades include variable-frequency drives on the supply fan, economizer dampers that pull in fresh outdoor air when temperatures allow, and demand-controlled ventilation that adjusts outdoor air as needed.
Have a Maintenance Plan In Place
Rooftop units offer an all-in-one heating and cooling solution for commercial spaces, with many running 24/7. As a result, routine maintenance is essential. Aim to have your RTU serviced by a commercial HVAC technician in Edmonton at least twice a year. A proactive maintenance plan can also support building owners by making this process more seamless throughout the year.
Maintenance tasks may include:
- Filter replacement
- Evaporator & Condenser coil cleaning
- Belt inspection
- Exhaust inspection
One of the crucial tasks that technicians perform is cleaning both evaporator and condenser coils. Even a small amount of buildup on coils can mean a significant loss in overall energy efficiency. In many cases, a neglected evaporator coil can lead to significant efficiency losses within a few months without service.
