My 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.

I had an extremely frustrating experience with this HVAC shop. I initially contacted them for A/C service and was quoted between $800 and $1,200. However, after inspecting the system, the cost jumped to $2,000. Just two days after their first repair, my A/C failed again, leading to an additional charge of $315 to replace a broken capacitor (which can be done in 15 mins by myself and cost only $20)
Although the dealer waived the cost later after this replacement, the system failed again within hours, prompting a third visit. During this visit, they discovered a leak in the evaporator coil and claimed to have fixed it. Unfortunately, shortly after that repair, the A/C failed yet again. This meant I had three separate repairs in one week, and the A/C still wasn’t working properly.
While the dealer has recently offered to replace the leaking coil at no charge and acknowledged their shortcomings, my trust in them has been severely shaken. I also requested a refund for the unsatisfactory service, but they refused. The dealer also admitted the mistakes they made during the visits in the email, including failing to replace the capacitor, failing to realize the evaporation coil may be old etc. The lack of thoroughness during repairs is unacceptable. Given these experiences, I feel compelled to leave a negative review. I advise others to be cautious when considering this shop for HVAC services.

Paul 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!
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.
