Why Indoor Air Quality Matters

Indoor air can be up to five times more polluted than outdoor air, especially in homes with limited ventilation or older HVAC systems. Poor air quality can lead to:

  • Allergy or asthma flare-ups
  • Dry skin, throat irritation, or sinus issues
  • Mold growth from excess humidity
  • Musty or stale odors
  • Reduced HVAC efficiency due to clogged filters and airflow issues

Caswell Heating & Air offers products and services that work alongside your existing HVAC system to clean, balance, and refresh the air in your home.

Our Indoor Air Quality Solutions

We provide a complete range of services and products to help you improve air quality and comfort, including:

Air Purification Systems

We install high-efficiency air purifiers that capture dust, pet dander, pollen, and other airborne particles. These systems reduce allergens and help protect your family from pollutants circulating through your ductwork.

Whole-Home Humidifiers and Dehumidifiers

Maintaining proper humidity levels prevents mold, reduces dry air symptoms, and helps your heating and cooling systems work more efficiently. We install humidity control solutions that integrate directly with your HVAC system.

Ventilation and Airflow Improvements

Poor ventilation leads to stale indoor air. We assess your home’s airflow and recommend changes to increase fresh air circulation, including duct modifications or system upgrades.

Filter Upgrades and Recommendations

Basic filters may not be enough to catch smaller particles. We help you select and install higher-efficiency filters suited to your HVAC system and lifestyle needs.

Integrated HVAC Solutions

Indoor air quality is closely tied to the performance of your heating and cooling systems. Caswell Heating & Air offers complete HVAC services, including furnace maintenance, AC repair, and thermostat installatio and repair, to ensure your system is running cleanly and efficiently.

If your system is aging or contributing to poor air quality, we can also provide guidance on furnace replacement or air conditioner upgrades.

Frequently Asked Questions

What areas do you serve?

We proudly serve Opelika and surrounding areas, including Auburn and the greater Lee County region.

Do you offer 24/7 emergency service?

Yes! When your AC or heater system goes down, we’re just a call away. Day or night, weekends or holidays, it doesn’t matter. We are here to help.

What brands do you service?

We work on all major HVAC brands and systems. Whether it’s a newer unit or an older model, we’ve got the experience to fix it right.

How do I know if I need a new AC or just a repair?

If your system is over 10–15 years old, constantly breaking down, or causing energy bills to spike, we can help you decide whether an ac repair or ac replacement is the smarter move.

Is your company licensed and insured?

Absolutely. We’re fully licensed in the state of Alabama and carry all required insurance for your peace of mind.

How often should I service my HVAC system?

We recommend a tune-up at least once a year. Ideally in spring for cooling and fall for heating. Regular HVAC maintenance keeps your system efficient and helps avoid costly breakdowns.

What’s included in a maintenance visit?

Our tune-ups include a full system inspection, cleaning, filter check, refrigerant level check, and performance testing. All designed to catch problems early and save you from needing a new unit.
