The Impact of Heatwaves on Your HVAC System

If you live in southeast Georgia then you know that every year around this time we wonder if it’s going to get any hotter and sure enough, it always does. So as summer temperatures soar, what have we grown accustomed to? Cooling down indoors. This is when it’s imperative that our HVAC systems (heating, ventilation, and air conditioning) don’t fail us.

We rely on our HVAC systems to maintain a comfortable indoor environment. However, during heatwaves, when temperatures reach extreme levels, your HVAC system may struggle to keep up with the demand, leading to potential problems and reduced efficiency.

Below are some of the impacts of heatwaves on your HVAC system:

Increased Workload and Strain: During a heatwave, your HVAC system works harder and longer to maintain the desired indoor temperature. This increased workload puts additional strain on the system’s components, such as the compressor, condenser, and evaporator coils. The constant running of the system can lead to faster wear and tear, increasing the likelihood of breakdowns and the need for repairs.

Reduced Efficiency: As outdoor temperatures rise, the efficiency of your HVAC system may decrease. The system must work harder to remove heat from your home and release it outside. When the temperature difference between the inside and outside of your home is significant, the system requires more energy to cool the air effectively, leading to reduced efficiency and higher energy bills.

Inadequate Cooling Capacity: If your HVAC system is not properly sized for your home or if it’s an older, less efficient model, it may struggle to maintain a comfortable indoor temperature during a heatwave. This can result in warm spots throughout your home, leaving you feeling uncomfortable and dissatisfied with your system’s performance.

Increased Risk of Refrigerant Leaks: Extreme heat can cause the refrigerant in your HVAC system to expand, putting additional pressure on the refrigerant lines and connections. This increased pressure can lead to refrigerant leaks, which not only reduce the system’s cooling capacity but also pose environmental and health risks. Regular maintenance can help identify and address potential leaks before they become a significant problem.

To minimize the impact of heatwaves on your HVAC system, we recommend that you:

  1. Schedule Regular Maintenance: Have your HVAC system serviced at least once a year to ensure it’s operating at peak efficiency. We can identify any potential issues before they escalate and improve your unit’s lifespan through routine maintenance.
  2. Change Air Filters Regularly: Dirty air filters restrict airflow and make your system work harder. Replace your filters monthly, or as recommended by the manufacturer, to maintain optimal performance.
  3. Use Fans and Window Coverings: Ceiling fans and strategically placed floor fans can help circulate cool air throughout your home, reducing the workload on your HVAC system. Closing blinds and curtains during the hottest parts of the day can also minimize heat gain.
  4. Adjust Thermostat Settings: Set your thermostat a few degrees higher during a heatwave to reduce the strain on your HVAC system. Every degree above 72°F can save you approximately 3% on your cooling costs.
  5. Consider Upgrading Your System: If your HVAC system is old or struggling to keep up with demand, consider upgrading to a more efficient, properly-sized system that can better handle extreme temperatures.
  6. Look Into a Home Dehumidifier: Our heat comes with humidity, and this puts more of a strain on your HVAC unit. Installing a home dehumidifier is an investment into the overall health of your system and will also make those summers much more tolerable.

By understanding the impact of heatwaves on your HVAC system and taking proactive measures to mitigate these effects, you can ensure that your home remains comfortable and your system operates efficiently, even during the hottest days of summer.
