Colorado’s spring winds are formidable, capable of unsettling both homes and their vital HVAC systems.
Even though these winds are a welcome sign of warmer weather to come, it’s best to prepare for their arrival and take proper precautions to ensure that the HVAC system is safe from potential damage.
Spring Winds
During the spring, the jet stream shifts from its winter to summer location, causing windy conditions. For some unknown reason, it is powerful in Colorado.
Increased Strain on the HVAC System
Strong winds can significantly strain the system, forcing it to work harder than necessary. The primary issue arises from the increased workload.
If a system is set to heating or cooling, strong winds can counteract its efforts by introducing hot or cold air from outside through leaks and cracks. In other words, conditioning the indoor and outdoor spaces is way above its capability.
Damage to the Outdoor Unit
Strong winds can carry and blow debris like leaves, twigs, and dust directly into the outdoor unit of the HVAC system.
These obstructions can cause substantial damage to the fan and the coil, which are vital components responsible for heat transfer and air circulation. If left unchecked, this can result in costly repairs or complete system replacement.
Short Cycling
Strong winds can cause rapid temperature changes, prompting the system to short cycle. Short cycling means the system turns on and off frequently, leading to unnecessary strain and increasing energy consumption. This constant switching can also damage the HVAC system’s compressor and other mechanical components.
Noise and Vibration
Extreme winds can make the outdoor unit vibrate more, causing noise and potential component misalignment over time. The system will experience decreased efficiency, and its overall lifespan will be shortened.
Higher Energy Bill
Any disruption to regular system operation, such as increased strain or short cycling, can lead to higher energy usage and, thus, higher bills. Energy waste can become a significant financial burden, especially when users use the HVAC system more frequently during extreme weather conditions.
Preventive Measures
Here are some ways users can be preventative and protect against strong winds.
Trimming Branches And Shrubs
Overhanging branches threaten the system, potentially shedding debris directly onto the unit and impeding proper airflow. Regular trimming, especially before solid winds hit, can prevent potential damage and maintain adequate ventilation for the outdoor unit.
Remember to keep at least a two-foot clearance around the unit to allow for proper air circulation and easy access for maintenance. Also, identify branches that seem particularly close or brittle and take preemptive action to avert a potential crisis.
Checking And Tightening Loose Elements
Wind exposure can loosen bolts, screws, and panels on the outdoor unit. Users can work closely with a technician to assess and tighten loose elements.
While doing so, users can ask them to check and, if needed, straighten the condenser fins (the metal pieces that protect the coils). Strong winds can bend them, significantly reducing their effectiveness.
Investing In Windbreaks
Strategically planting windbreaks near the unit can significantly reduce the force of direct winds. Fast-growing vines like English Ivy and Virginia Creeper are great options if users don’t want to wait long for results. One could also use a fence, lattice, solid wind panels, or wind deflection boards for a more immediate solution.
Protecting The Unit During Storms
A weatherproof cover is a simple and effective defense when forecasts call for extreme wind or precipitation. Remove it promptly once the storm subsides to avoid a moisture trap.
Moreover, ensure that the cover is specifically designed to protect HVAC units. It must be well-ventilated and have secure fastenings to prevent flying away or damage to the unit itself. Also, be sure to monitor the temperature inside the unit to avoid overheating.
Maintenance Suggestions
After a strong wind storm, users need to have their system inspected.
Inspect And Clean Air Filters
Clean air filters are the unsung heroes of a healthy and efficient HVAC system. They actively trap dust, dirt, pollen, pet dander, and other particles the wind brings into the home.
Airflow is inhibited when they become clogged or dirty, and the system’s overall efficiency drops. In severe cases, part of the HVAC, like the blower fan, may fail, resulting in costly repairs.
Check Ductwork For Leaks
Gaps or leaks in the ductwork can cause significant energy losses, especially when the system is working harder than usual to keep up with changing weather conditions. Strong winds can blow open loose duct connections or even deposit outdoor debris into the ducts.
Indoor Air Quality Management
Investing in air purifiers during spring and summer can help improve a home’s indoor air quality
Along with cleaning or actively replacing the air filters, investing in air purifiers during spring and summer can help improve a home’s indoor air quality. These units help filter out pollen, microbial contaminants, and other allergens circulating in the air.
Also, use humidifiers or dehumidifiers to control moisture levels in the home. Humidity is often unpredictable in spring, especially when winds can easily deposit or remove moisture indoors.
Granted, be strategic about how to open the windows. Avoid opening windows when the wind is high, as this can let in outdoor pollen and other allergens. On calmer days, open the windows for short periods to increase ventilation and fresh air.
Monitoring Thermostat Settings
Spring can deliver temperatures that range across the spectrum, but using the thermostat wisely can save users energy and money. On warmer days, consider keeping the thermostat at a higher temperature to reduce the workload on the system. When cooler days hit, adjust accordingly.
Consider investing in a programmable thermostat to adjust temperatures automatically based on the schedule. Smart thermostats can save money by reducing unnecessary heating or cooling when no one is home.
Work With a Professional HVAC Technician
Many manufacturers stipulate regular professional maintenance as a condition for honoring warranties
Steps like changing filters, visually inspecting air ducts for debris or mold, and dusting vents are pretty straightforward and can be done by most homeowners. However, it’s essential to collaborate with a professional HVAC technician to address and resolve any potential issues effectively.
HVAC professionals have seen it all and understand the specific challenges of Colorado’s climate. They can easily spot potential problems and provide necessary repairs or maintenance to ensure the system is functioning at its best.
Additionally, many manufacturers stipulate regular professional maintenance as a condition for honoring warranties. By working with one of Premier’s HVAC technicians, users can avoid voiding the warranty and potentially save on costly repairs down the line.
