Is It Time to Replace Your HVAC System?
If you’re a building owner or facility manager, knowing when to replace your commercial HVAC system can be challenging. Recognizing the signs that indicate a need for a new HVAC unit is crucial for maintaining efficiency, reducing energy costs, and ensuring comfort in your facility.
Continue reading this blog to determine whether your HVAC system needs replacement or just a few repairs.
Decreasing Energy Efficiency and Rising Utility Bills
One of the most apparent signs that it might be time to consider a new HVAC system is a noticeable decrease in energy efficiency, often reflected in steadily rising utility bills. According to the U.S. Department of Energy, HVAC systems can account for about 40% of the electricity commercial buildings use. An aging or malfunctioning system—whether an air conditioner or the overall HVAC unit—must work harder to maintain temperature, which increases energy usage.
Higher Energy Usage No Matter the Settings
If your energy usage remains high despite moderate thermostat settings, it could signal declining efficiency. This inefficiency can stem from various issues, including problems with the compressor, refrigerant leaks, or inefficient ductwork, all contributing to the system’s reduced capability to regulate temperature.
Utility Bills Spiking Over Time
Despite no significant change in usage habits, a consistent pattern of rising energy bills over time suggests that your system is becoming less efficient. This spike in energy costs is a sign that your HVAC system, especially crucial components like the air conditioning unit, may need an upgrade. Upgrading to a newer, more energy-efficient system could significantly reduce these costs and improve overall energy usage in your facility.
Frequent Repairs and Downtime
Frequent repairs in an HVAC system are not just inconvenient; they signal that the system may be approaching the end of its useful life.
Repair Bills Mounting
The cost of ongoing repairs for your air conditioner or HVAC unit can quickly add up, sometimes even exceeding the investment in a new, more efficient system. This financial burden is particularly evident in systems still using R-22 refrigerant, which is being phased out and is increasingly expensive and difficult to source. Continual investment in an aging system can be less cost-effective than opting for a modern, energy-efficient replacement.
More Unplanned Downtime and Disruptions
Frequent breakdowns that lead to unplanned outages are more than just operational hiccups; they can significantly disrupt business operations and adversely affect tenant comfort. A Building Services Research and Information Association (BSRIA) study noted that regular maintenance could reduce system breakdowns by as much as 70% and lower the risk of unplanned downtime. This high frequency of repairs and disruptions often indicates that an HVAC system requires a comprehensive assessment and possibly a replacement.
Age and Obsolescence: When Units Are Past Their Prime
HVAC systems, including central air units, typically have an average life span of 15 to 20 years. Beyond this period, they become less efficient and reliable, leading to increased operational costs and decreased performance.
Outdated Technology Lacking Modern Features
Older HVAC systems often lack the advanced features and capabilities of newer models. For instance, modern units are equipped with smart thermostat capabilities, ENERGY STAR ratings for improved efficiency, and enhanced air quality features, all of which contribute to better system performance and energy savings. The U.S. Department of Energy notes that upgrading an HVAC system could save 20-40% on heating and cooling costs.
Exceeding the Recommended Operational Life Span
Operating an HVAC system beyond its recommended life span increases the likelihood of frequent repairs, elevates energy bills, and reduces the effectiveness of cooling and heating functions. Investing in a new, high-efficiency HVAC system can be financially beneficial in the long run.
Prolong Equipment Life with Proactive Replacement
Proactively replacing your HVAC system before it completely breaks down can save you from emergencies, reduce energy costs, and provide better comfort and air quality. Upgrading to a new system with a solid warranty can be a strategic move toward energy efficiency and saving money.
