Many business owners and facilities managers rely on common sense for preventing commercial HVAC problems. The truth is, common sense isn’t all that common – mistakes are made that could be avoided, saving your business or facility the hassle and expense of commercial heating and cooling shutdowns.
These are the 10 most common commercial HVAC problems facilities face and what you can do to prevent them. For help with your commercial heating or cooling system, contact Estes Commercial for quick, reliable help.
- Neglecting Maintenance
When routine maintenance is skipped, commercial HVAC problems flourish. Unmaintained systems use excessive energy, can’t keep up with the facility’s heating and cooling demands and break down more frequently. Skipping maintenance raises the cost of operation, creates comfort inconsistencies throughout your building and can shut down operations without notice when breakdowns occur.
Commercial HVAC systems should be professionally maintained twice a year. Contact Estes Commercial to create a preventative maintenance plan to provide the care your systems need to run optimally and efficiently.
- Dirty Furnace Filters
When furnace filters aren’t changed on a regular basis, your commercial HVAC system expends more energy to move air through the facility. Your system is stressed, leading to breakdowns which are likely to reduce the system’s service life.
Schedule furnace filter replacement on a quarterly basis or per the filter manufacturer’s recommendation. Your maintenance staff should check filters monthly to determine if replacement is needed sooner, especially in the summer and winter months.
- Thermostat Malfunctions
Malfunctioning thermostats cause your HVAC system to operate unnecessarily, fail to operate and cause discomfort. Check thermostat batteries regularly, have your HVAC technician test their calibration and ensure thermostats are not located near windows, doors or heat sources that could cause false readings.
- Air Imbalances
When airflow imbalances occur in your building’s ductwork, you’ll experience temperature fluctuations and uneven temperatures throughout. Dampers work to regulate airflow, so ensure they are functioning properly, allowing conditioned air to reach its intended destination.
- Refrigerant Leaks
If refrigerant is leaking from your commercial HVAC system, the system will have a difficult time cooling and dehumidifying indoor air. Refrigerant leaks force the system to overwork to make up for the losses, consuming excess energy and burdening components.
Your HVAC technician can inspect your refrigerant lines for leaks, repairing them and recharging your system if needed.
- Noisy Operation
Noisy operation can be a distraction and is indicative of commercial HVAC problems. Rattling may indicate loose ducts or components, squealing can be a sign of a bad fan belt, grinding may tell you bearings are worn.
Have your technician inspect the system if you notice strange operating noises. You want to fix these issues immediately before further damage is done to the system, causing expensive repairs and downtime.
- Improper HVAC Capacity
If your commercial HVAC systems aren’t sized properly for your facility, they will operate inefficiently, costing your business more money. They also prohibit you from depending on them to provide climate control.
An HVAC technician should perform heating and cooling load calculations for your facility to ensure the systems installed are the proper capacity. If your systems are under or oversized, consider replacing them to improve efficiency and conserve operating expenses.
- Clogged HVAC Drain Lines
When commercial HVAC drain lines become clogged with dirt and algae, condensation cannot properly exit the system. Water can back up, damaging the HVAC system and surrounding areas.
Inspect drain lines regularly and clean the lines as well as drains to prevent clogs and the expensive water damage that may result.
- Blown Fuses
If your commercial HVAC system is blowing fuses or tripping breakers regularly, components within the system may be overheating or wiring within it may be damaged. Blown fuses and tripped breakers shut down your HVAC system, causing discomfort and disruption to your staff and operations.
If blown fuses and tripped breakers are a constant problem, have your HVAC technician inspect your system to identify the source and perform needed repairs.
- Poor Indoor Air Quality
Poor indoor air quality in a facility causes discomfort, illness and lost productivity among your workforce. Avoid indoor air quality issues by changing furnace filters regularly and discussing indoor air quality solutions with your commercial HVAC company to better the environment in your facility and address the specific problems you face, such as UV lights or dehumidification systems.
