Even before the cold weather sets in you should have your HVAC system inspected by a licensed professional. A well-tuned system provides comfort and even temperatures throughout your property. As winter sets in, the demands on your system increase. While winterizing HVAC systems for commercial buildings or multi-site properties can be a demanding task, a thorough inspection and series of check points are essential for reducing unnecessary future maintenance and expenses. Here are a few considerations to consider when implementing facilities winter HVAC and energy plans…
Replace and Check Filters
Most properties have some sort of furnace or heat pump, and many of those properties (especially newer ones) have combined heating, ventilation and air-conditioning or HVAC systems. Each type uses some type of air filter or screen to prevent larger airborne particles (up to 40 microns) from entering the system and clogging sensitive machinery. Consider changing air filters 3-4 times per year. Higher quality filters can save you money on maintenance and replacement cost.
Preventative Maintenance Schedule
Regular HVAC preventative maintenance is the best way to ensure trouble-free operation and peak performance. Pre-season maintenance is also important. It can help to avoid a system failure in severe hot or cold weather when you need it most, and it can also keep your energy bill from getting out of hand. Establishing a commercial HVAC maintenance agreement with expert professionals is a great way to keep your system running. Studies have shown that routine maintenance is a key driver in energy efficiency for commercial HVAC system.
Determine the Best Setting for Your Thermostats and Stick to a Plan
A thermostat is the main point of interface between your property and your HVAC system. When your thermostat is accurate, it’s easier to make fine adjustments that will keep your home comfortable and your energy bill low. Like all components of your property HVAC system, thermostats require periodic repairs and maintenance to keep working their best over the long term. As cold winter months approach, a professional commercial HVAC technician calibrate all the thermostats in your commercial property
Check All Equipment for Leaks or Holes
Since heated air escapes through the leaks in your ducts, your furnace has to heat longer to match your thermostat setting. And a longer running time=higher energy bills. Building owners and operation directors should always work with HVAC consultants to identify ways to make facilities more safe and efficient. HVAC is the obvious place to look for safety hazards. It is essential to make sure there are no holes in the heat exchanger and all tubes and orifices are free of debris
Make Sure Economizers Are Operating Properly
The function of the economizer is, as its name implies, to “economize” or save on cooling costs. The component allows the unit to use outdoor air for cooling, provided the ambient air is below a certain temperature and the humidity is below a certain percentage. If the economizer dampers are struck closed you will not be able to take advantage of free cooling. It is extremely important to work with your HVAC specialist to ensure that your economizer is operating properly.
Working with a service contractor that understands the history of each of your facilities and the energy challenges faced will not only keep your units running efficiently, but reliably longer. Be sure a preventive maintenance plan is tailored to meet the unique needs of your commercial facilities to provide the most comfortable and safe environment.
