Common Summer Allergies In Your Home and Their Impact

Ever notice that you start sneezing more when spring & summer roll around? You're not alone. Here's a quick rundown of the usual allergen suspects:


  • Pollen: Trees, grasses, and weeds release pollen, which can enter your home through open windows and doors.


  • Mold Spores: Warm and humid conditions promote mold growth, releasing spores into the air.


  • Dust Mites: These tiny creatures thrive in higher temperatures and humidity, contributing to indoor allergens.


  • Pet Dander: Pets often shed more in warmer months, increasing the presence of dander in your home.


These allergens can cause symptoms like sneezing, coughing, itchy eyes, and exacerbated asthma. Maintaining good indoor air quality is essential for reducing these symptoms and ensuring a healthy living environment.

The Role of Your HVAC System in Filtering Air

Your HVAC system is your best friend when it comes to keeping indoor air fresh. Here’s how it helps:


  • Air Filters: Quality air filters trap dust, pollen, and other particles. High-efficiency filters, such as HEPA filters, can capture even smaller particles.


  • Air Purifiers: Standalone or integrated air purifiers can remove contaminants from the air, providing an extra layer of protection.


  • Ventilation: Proper ventilation helps reduce indoor pollutant levels by bringing in fresh outdoor air and expelling stale indoor air.


  • Humidity Control: Your HVAC system can regulate indoor humidity levels, preventing the growth of mold and dust mites.


Regular maintenance and upgrades to your HVAC system can significantly improve its effectiveness in maintaining good air quality.



Our top tips for an allergen free home: 1. Clean & Change Air Filters Regularly:          Helps combat dust and pollen.          2. Upgrade to HEPA Filters:          Capture 99.97% of airborne particles.          Helps with pet dander and smoke particles.  3. Use Air Purifiers:          Helps combat allergens, dust, and bacteria.  4. Ensure Proper Ventilation:          Open windows and use exhaust fans.          Helps combat indoor pollutants and stale air.  5. Use Dehumidifiers:          Helps combat mold and dust mites.


Impact of HVAC Upgrades on Indoor Air Quality

Upgrading your HVAC system can drastically improve indoor air quality. Here’s a snapshot of the improvements you might see:
