As winter fades and temperatures rise, commercial building managers often face unexpected HVAC failures, increased energy costs, and poor indoor air quality. If your system isn’t prepared for the seasonal transition, you could experience costly inefficiencies and discomfort for tenants.
For 16 years, Harold Brothers Mechanical, Inc. has helped businesses optimize their HVAC systems, lower energy costs, and prevent unexpected breakdowns. We know that proactive maintenance and smart energy upgrades are key to keeping your system running efficiently year-round. Whether you need routine inspections, coil cleaning, or advanced solutions like smart thermostats, our team is here to help you stay ahead of costly repairs and ensure peak performance.
In this guide, you’ll learn the 12 best HVAC practices to get your system spring-ready, covering everything from preventative maintenance to energy-saving upgrades.
A thorough HVAC inspection catches small issues before they become expensive repairs. A professional spring inspection should include:
✔ Checking air filters, coils, and ductwork for dirt and debris
✔ Inspecting belts, pulleys, and moving parts for wear
✔ Ensuring electrical connections are secure
✔ Testing thermostats and system controls for accuracy
✔ Checking for refrigerant leaks
Preventative inspections help avoid costly breakdowns during peak cooling months. A well-maintained system also ensures optimal indoor comfort, keeping employees and tenants satisfied.
Spring allergens like pollen and dust can clog air filters, reducing airflow and increasing energy use. Regularly replacing or cleaning air filters ensures:
✔ Better indoor air quality
✔ Less strain on your HVAC system
✔ Lower energy costs
Consider high-efficiency HEPA filters, which capture up to 99.97% of airborne particles, significantly improving indoor air quality.
Over time, dust, pollen, and mold spores accumulate in air ducts, impacting both air quality and system performance. A spring duct cleaning helps:
✔ Reduce allergens and airborne contaminants
✔ Improve overall airflow and efficiency
✔ Prevent mold and bacteria buildup
If leaks or damage are found, sealing ducts can further improve energy efficiency and lower utility bills.
A well-calibrated thermostat prevents energy waste and ensures comfort. For spring, make sure to:
✔ Test thermostat accuracy
✔ Adjust settings for warmer temperatures
✔ Upgrade to a smart thermostat for automatic energy adjustments
Smart thermostats learn occupancy patterns and adjust temperatures automatically, saving up to 10% on energy bills. Many models also allow for remote access, giving building managers greater control.
Dirty condenser and evaporator coils reduce heat exchange efficiency, making your system work harder and use more energy. Regular cleaning:
✔ Enhances cooling performance
✔ Reduces energy consumption
✔ Extends the life of HVAC components
Clean coils twice a year, particularly before and after high-use seasons like summer and winter.
Low refrigerant levels can lead to:
✔ Poor cooling performance
✔ Higher energy use
✔ Potential compressor damage
A refrigerant leak can be costly—if levels are low, a technician should check for leaks before refilling to prevent ongoing issues.
Proper ventilation prevents stale air, excess humidity, and allergen buildup. To ensure optimal indoor air quality:
✔ Check air exchange rates
✔ Inspect ventilation fans for dust buildup
✔ Consider installing UV purification or HEPA filtration
UV light systems eliminate bacteria and viruses, further improving indoor air quality.
Spring moisture can clog condensate drains, leading to:
✔ Water leaks and structural damage
✔ Mold and mildew growth
✔ High indoor humidity levels
Flush drainage lines to remove blockages and prevent costly damage. Check drain pans for standing water, which may indicate clogs.
Routine maintenance extends equipment life and reduces repair costs. A professional tune-up should include:
✔ Lubricating moving parts
✔ Inspecting fan motors and belts
✔ Checking heat exchangers for cracks
✔ Testing system safety controls
Preventative maintenance can cut repair costs by up to 40% and ensure that your system runs efficiently year-round.
If your HVAC system is 10+ years old, upgrading to energy-efficient components can significantly cut costs. Consider:
✔ High-efficiency air handlers
✔ Variable-speed fans
✔ Zoning systems for precise temperature control
Newer HVAC technology lowers operational costs and may qualify for tax incentives or rebates
A well-insulated building reduces HVAC workload and maintains consistent temperatures. To maximize efficiency:
✔ Inspect for gaps around windows, doors, and ductwork
✔ Seal leaks to prevent cooled air from escaping
✔ Upgrade insulation in key areas
Proper insulation can reduce heating and cooling costs by up to 30%.
Building occupants play a major role in energy efficiency. Encourage them to:
✔ Keep windows and doors closed when HVAC is running
✔ Report HVAC issues promptly
✔ Adjust thermostats appropriately
Awareness = Savings: Small behavioral changes can reduce HVAC energy use by 5-15%.
More businesses are incorporating renewable energy into their HVAC systems, including:
✔ Solar-powered HVAC units
✔ Geothermal heating and cooling
✔ Energy recovery ventilation (ERV) systems
These eco-friendly solutions can further reduce costs and environmental impact.
Keeping your HVAC system in top shape saves money, prevents breakdowns, and ensures reliable performance—especially in the spring when demand increases. Simple tasks like cleaning filters, checking refrigerant levels, and inspecting ductwork help it run efficiently and avoid unnecessary strain from winter wear.
Regular maintenance—such as coil cleaning and thermostat adjustments—can lower energy bills, extend your system’s lifespan, and improve overall efficiency. If your HVAC system has outdated components, upgrading key parts like thermostats or motors can enhance performance and cut costs. A little maintenance now means a hassle-free, energy-efficient system when you need it most.
