So after a quick 15 minute inspection he charged us 160 dollars suggesting us to replace the entire unit.

Would not recommend anyone go with this company.

Just a heads up, they will only service equipment IF they installed it…read more I have never heard of a service company not willing to work on equipment installed by someone else. If you buy a house, you may not know who installed it. Last week Wednesday (1/7) I called because we had a mini-split installed (DIY) and I was told that before you turn it on, have an HVAC company come out and test it, check the pressure in the lines and then turn it on. When I called, the nice lady on the phone said that they do not diagnose or work on equipment unless they have done the installation. OK, no problem, I called their "sweet" competitor and they sent out a technician within 48 hours to do the job. 2 stars only because the lady on the phone was nice, although again, I am shocked that a service company will not do service calls

Review for DHA Mechanical…read more I hired DHA Mechanical for an HVAC system evaluation. The diagnostic fee was $525 -- which felt high compared to other companies I spoke with, but to be fair, the technician spent over two hours on-site and provided a detailed report. The cost seemed tied to time and expertise, not just a flat service fee. I spoke with Paul afterward (likely the owner), and he was clearly knowledgeable, especially about zoning and more complex HVAC setups. If you're looking for a high-end, white-glove install, DHA might be a good fit. That said, there were a few misses. The attic access cover wasn't put back after the evaluation. Paul acknowledged the oversight as a simple mistake, but no one returned to address it until a day or two later, despite me notifying them promptly. More importantly, the system replacement bid I received wasn't competitive -- significantly higher than other reputable proposals -- which made the upfront diagnostic feel like a sunk cost rather than a step toward a practical solution. Bottom line: DHA brings solid technical know-how, but expect premium pricing. Clarify what your evaluation includes up front -- and keep shopping if cost is a key factor.

None of the technicians were wearing foot coverings or company uniforms, despite your response…read moreclaiming otherwise. The photos clearly show this. Also, the issue was never that the bed was "blocking access." There was more than enough room to either move the bed properly, ask if a ladder was available, or simply arrive with the correct equipment in the first place. Using a customer's bed as a tool was completely inappropriate and unprofessional. As for the restroom situation, there is proof of your technician entering and exiting the restroom, and immediately afterward urine was left on the toilet seat and bathroom floor. That mess was not there beforehand. Calling it an "allegation" instead of addressing the concern respectfully is disappointing. I shared my honest experience as a customer. Professionalism is not just about completing a job it's also about respecting someone's home, cleanliness, and basic courtesy while inside it.
