- DGDavid GoetzJan 11, 20261.0My family had a very disappointing experience with DHA Mechanical. My heating unit was only one year old and still under warranty, yet I ended up paying almost $800 out of pocket. A technician spent about four hours sitting on my roof only to determine that the igniter was bad—something that should not have taken that long to diagnose. What upset me the most was the complete lack of transparency. Nobody was upfront about the costs during or after the service visit. I only found out about all the additional fees 4 days later, after we had to call them ourselves to ask when we can get heat back on since it’s in the cold winter months. This level of service work is unacceptable and they should not be used for any warranty work. Between the overpricing, the inefficient troubleshooting, and the poor communication about fees, I do not feel this company operates in a customer-friendly or honest way. I would not recommend DHA Mechanical to anyone looking for fair pricing or clear, upfront service. I believe this company exploits families with their high labor costs on cheap parts under warranty to stay in business.
- KLKaren L.Jul 23, 20245.0First and foremost, if it wasn’t for Sheri and her boss Paul being so empathetic to my situation (no air for 5 days at the time) I would not have had the pleasure of working with DHA. Paul managed to squeeze me into his busy schedule the day I called…amazing! On site, he solved one problem only to have technician Jorge find another which required a part that had to be ordered. Once ordered, technician Anthony meticulously completed the repair. I am thoroughly satisfied with DHA’s quality of work, fair price and the exemplary, friendly customer service! Thank you Everyone!
- SRSenthil RajaDec 12, 20235.0Paul and his team are very helpful and care about their customers. They are very knowledgeable. My house was having heating issues. They diagonised the problem in my HVAC unit in short time, provided fair quotes and completed the work in a timely manner. The office staff is very nice and attentive. I appreciate you all. I would highly recommend DHA Mechanical to anyone!
- CHChris HauptSep 10, 20235.0Paul and his team are very knowledgeable. Our house from 1998 was having heat as well as AC issues. On all occasions DHA was quick to respond and had fair quotes. I will continue to use them.
Frequently Asked Questions About DHA Mechanical, Inc.
How do I know which indoor air quality product is right for me?
Finding the right indoor air quality solution depends on your specific comfort requirements and sensitivity levels. If you have higher tolerance to irritants, simply upgrading to a better air filter may be sufficient. For those more sensitive to airborne triggers, we recommend an air purification system for more effective reduction of irritants. At DHA Mechanical, we provide a Home Health Report Card service to help you identify the most appropriate indoor air improvement products for your particular needs.
How can I eliminate indoor odors?
While temporary solutions like air fresheners and candles might mask odors, they don't solve the underlying issue and may introduce potentially harmful chemicals into your living space. A more effective approach is installing germicidal (UV) lights in your HVAC system, which eliminate odors by destroying bacteria and preventing biological contaminant growth. These lights also sterilize surfaces within your HVAC equipment, enhancing overall air quality. If ventilation issues are contributing to odor problems, our DHA Mechanical technicians can evaluate your home comfort system and suggest improvements for better air circulation.
How healthy is my indoor air?
According to EPA research, indoor air can contain up to 100 times more pollutants than outdoor air. Regular cleaning helps but cannot remove all airborne contaminants. To enhance your indoor air quality, consider utilizing filtration solutions such as UV light units, air filters, energy recovery ventilators (ERVs), heat recovery ventilators (HRVs), or electronic air cleaners. Our team at DHA Mechanical can offer professional guidance on which indoor air improvement devices would be most effective for your particular circumstances.
Why do I need to change my filters regularly?
Regular filter replacement is essential for maintaining your heating and cooling system's efficiency and improving indoor air quality. Timely changes ensure proper airflow and help reduce dust, allergens, and germs in your home. Replacement frequency varies by filter type, ranging from weekly to monthly intervals. Your DHA Mechanical technician can advise on the most appropriate filters and replacement schedule for your specific units to maintain maximum system performance and air quality.
How do I determine the right indoor air quality product for my home?
The right indoor air quality product depends on your individual comfort and sensitivity levels. DHA Mechanical offers a Home Health Report Card to help select the best indoor air improvement products for you.
What is the best way to eliminate indoor odors effectively?
Instead of masking odors, address their root causes like bacteria, dust mites, pet dander, and mold. Installing germicidal UV lights in your HVAC system can neutralize odors, and DHA Mechanical can recommend ventilation improvements.
How healthy is indoor air compared to outdoor air?
Indoor air pollution can be significantly higher than outdoor levels. Various filtration devices like UV lights, air filters, and ventilators help remove airborne particles. DHA Mechanical can advise on the best devices for your needs.
