When people think about their HVAC system, they often think about heating and cooling. Indoor air quality (IAQ) consideration is just as important, especially if someone in your home has asthma, allergies, or other respiratory issues. Some effects of poor IAQ include fatigue, headache, congestion, dry skin, and so forth. For now, you may have no symptoms at all; still, your health in the future might be impacted due to poor air quality.
At DT Air Conditioning & Heating, we believe everyone deserves a good and comfortable home experience. Therefore, we provide customized indoor air quality services to help clear away airborne pollutants and create a healthier space. From whole-home purification systems to dehumidifiers, duct sealing, or other specific fixes, everything we do is tailored to your unique needs and not an off-the-shelf template.

The approach we take is the hands-on approach; it's fully comprehensive. We never install a filter and walk away. We evaluate your entire system and assist you in choosing which tools would work best for your home. Here's a list of some of the solutions we provide:
Advanced systems remove particulates from the air, including bacteria, pollen, pet dander, and VOCs, which makes them ideal for relieving allergy and asthmatic symptoms.
Moisture control inside your home will prevent mold and bring comfort through all seasons.
Dust and allergens accumulate in the ductwork over time. Cleaning and sealing the ducts can dramatically improve airflow and air quality.
With the ability to trap fine particles, high-efficiency filters prevent their circulation through your air.
We help bring fresh air in while removing stale air, making your environment a place of fresher and more balanced air.
A well-maintained AC system doesn’t have to work as hard to cool your home. Clean coils, proper airflow, and correctly calibrated components help reduce energy consumption.
Benefits include:
Competitor resources consistently note that neglected systems without proper AC maintenance often lose efficiency long before they fail completely.
Many AC failures don’t happen suddenly—they develop over time. Maintenance allows technicians to identify worn parts, loose connections, or airflow problems before they cause system shutdowns.
Preventive maintenance helps:
Air conditioners are major investments. Regular maintenance helps protect that investment by reducing wear and tear on critical components.
Routine service can:
In many cases, maintenance can add years to the usable life of an AC system.
Maintenance isn’t just about the equipment—it’s about how your home feels. A tuned system delivers better airflow and more consistent temperatures.
Homeowners often notice:
For homes with airflow challenges, duct-related services may also help.
During maintenance, filters and internal components are checked for dust and buildup that can affect air quality.
Regular service supports:
This is especially important for households with allergies or respiratory sensitivities.

Common consequences include:
Many emergency service calls we receive in Plano could have been prevented with routine maintenance.
Most manufacturers and HVAC professionals recommend professional AC maintenance at least once per year—ideally before peak cooling season.

AC Repair:
Maintenance reduces the likelihood of needing repairs, but repairs may still be necessary as systems age.
Even if your system is still running, these signs suggest maintenance is overdue:
If these symptoms sound familiar, scheduling maintenance now can help restore performance.
Yes. Annual maintenance helps keep your system efficient, reliable, and operating within manufacturer guidelines, especially in Plano’s demanding climate.
Maintenance can’t prevent all repairs, but it significantly reduces the risk of major breakdowns by catching small issues early.
A clean, well-adjusted system operates more efficiently, which often results in lower energy usage and reduced utility costs.
Over time, neglected systems lose efficiency, require more repairs, and tend to fail earlier than well-maintained units.
Basic tasks like filter changes are helpful, but professional maintenance includes inspections and adjustments that homeowners can’t safely or effectively perform on their own.
We approach maintenance as more than a checklist. Our technicians focus on system health, performance, and long-term reliability—while clearly explaining what we find and why it matters.
