How Seasonal Allergies and AC Repairs Are Connected

When spring and summer roll around, most people in Rockwall and surrounding areas look forward to the warmer weather and blooming landscapes. But for many, the change in seasons also signals the start of allergy season — with sneezing, itchy eyes, and congestion becoming daily struggles. While most people chalk up seasonal allergies to pollen alone, there’s another factor that could be contributing to your symptoms: your air conditioning system.

Yes, your AC can play a major role in how severe your allergy symptoms are. Even more importantly, neglecting routine AC maintenance or needed repairs could make the problem worse. At D-N-D Services, we understand how important it is to not only keep your home comfortable but also healthy — and your HVAC system plays a key role in that balance.

How AC Systems Affect Indoor Air Quality

Your air conditioner does more than cool the air. It also helps filter out particles like pollen, dust, and mold spores — the exact allergens that make you feel miserable. However, when an AC unit is clogged, outdated, or poorly maintained, it can circulate these particles throughout your home rather than removing them.

Dirty filters, leaking ductwork, mold growth inside coils or ducting, and poor ventilation all contribute to diminished indoor air quality. If your system hasn’t been cleaned recently or you’re overdue for a repair, allergens can build up and continuously cycle through your home or workplace. This can make allergy symptoms worse, even indoors.

Common HVAC Issues That Impact Allergies

Here are some HVAC issues we see often at D-N-D Services that can directly contribute to allergy flare-ups:

1. Clogged or Dirty Filters: Your air filter should be replaced regularly to ensure it’s capturing pollen, dust, and other irritants. A dirty filter lets these allergens recirculate.
2. Mold in the System: Condensation within your unit or ducts can create a breeding ground for mold and mildew. Spores from these growths can trigger serious respiratory reactions.
3. Leaky Ducts: If your ducts are damaged or not sealed properly, allergens from attics, basements, or crawl spaces can be pulled into your airflow.
4. Improper Humidity Levels: Your HVAC system helps regulate humidity. Too much moisture in the air encourages mold growth, while too little can dry out your sinuses and make you more sensitive to airborne particles.

The Importance of Professional AC Maintenance

Routine maintenance is essential — not just for the performance of your AC, but for your health. At D-N-D Services, our NATE-certified technicians perform comprehensive inspections and cleanings of HVAC systems to ensure they are operating efficiently and safely.

During a maintenance appointment, we clean components, check for leaks, inspect filters, and evaluate your ductwork. We also offer duct cleaning services, which can remove years of dust, pollen, pet dander, and even mold from your ventilation system.

We also specialize in indoor air quality assessments, which include duct leakage testing and manual J load calculations to ensure your system is operating as efficiently as possible while improving the quality of the air you breathe.
