I recently had service by DHA, and couldn't be happier with the experience. The technician arrived on time, was professional and explained everything in a way that was easy to understand. I appreciated the follow-up by email from Sheri with the full detail on what was performed and completed or if any work is still pending. I highly recommend DHA, for their expertise and excellent customer care.
Frequently Asked Questions About DHA Mechanical, Inc.
How do I know which indoor air quality product is right for me?
Determining the right indoor air quality product depends on individual comfort needs and sensitivity levels. Those with high thresholds may benefit from simple solutions like improved air filters, while those with lower thresholds might require more comprehensive air purification systems. DHA Mechanical can provide a Home Health Report Card to assist you in selecting the most suitable indoor air improvement products for your specific situation.
How can I eliminate indoor odors?
Rather than masking odors with air fresheners or candles, which can potentially worsen air quality, consider addressing the root causes. Common sources of indoor odors include bacteria, dust mites, pet dander, and mold. Installing germicidal (UV) lights in your HVAC system can effectively neutralize odors and inhibit contaminant growth. Additionally, poor ventilation often contributes to unpleasant smells. A DHA Mechanical technician can assess your home's ventilation system and recommend solutions to improve air circulation and quality.
How healthy is my indoor air?
Indoor air pollution can be significantly higher than outdoor levels, according to EPA studies. While regular cleaning helps, it can't eliminate all airborne particles. Various filtration devices, such as UV light units, air filters, energy recovery ventilators (ERVs), heat recovery ventilators (HRVs), and electronic air cleaners, can effectively remove smaller particles. DHA Mechanical can advise you on the most appropriate indoor air improvement devices for your specific needs.
Why do I need to change my filters regularly?
Consistent filter replacement is crucial for maintaining optimal heating and cooling system performance and enhancing indoor air quality. Regular changes ensure proper airflow and help keep your home free of dust, allergens, and germs. The frequency of replacements varies depending on the filter type, ranging from weekly to monthly. Your DHA Mechanical technician will recommend the most suitable filters and replacement schedule for your specific system.
