  • How do I know which indoor air quality product is right for me?

    Selecting the appropriate indoor air quality product depends on your specific comfort needs and the sensitivity levels in your home. For those with higher tolerance thresholds, a simple upgrade to a better air filter might suffice. However, if you're more sensitive to irritants, an air purification system may be necessary to reduce triggers effectively. DHA Mechanical offers a Home Health Report Card service to assist you in determining the most suitable indoor air improvement products for your situation.
  • How can I eliminate indoor odors?

    While air fresheners and candles may temporarily mask odors, they don't address the root cause and can potentially introduce harmful chemicals into your home. A more effective solution is to install germicidal (UV) lights in your HVAC system. These lights help eliminate odors by killing bacteria and inhibiting the growth of biological contaminants. They also sterilize surfaces within the HVAC system, improving overall air quality. If poor ventilation is contributing to odor issues, a DHA Mechanical technician can assess your home comfort system and provide recommendations to improve air circulation and ventilation.
  • How healthy is my indoor air?

    Indoor air can contain up to 100 times more pollutants than outdoor air, according to EPA studies. While regular cleaning helps, it can't eliminate all airborne particles. To improve indoor air quality, consider using filtration devices such as UV light units, air filters, energy recovery ventilators (ERVs), heat recovery ventilators (HRVs), or electronic air cleaners. DHA Mechanical can provide expert advice on which indoor air improvement devices would be most beneficial for your specific situation.
  • Why do I need to change my filters regularly?

    Consistent filter replacement is crucial for maintaining optimal performance of your heating and cooling system and enhancing indoor air quality. Regular changes ensure proper airflow and help keep your home free from dust, allergens, and germs. The frequency of replacements varies depending on the type of filter you use, ranging from weekly to monthly. Your DHA Mechanical technician can recommend the most suitable filters and replacement schedule for your specific units to ensure peak system efficiency and air quality.
