When he arrived, the first thing he did was to put on plastic shoe covers so he didn't enter our house in his street shoes. That showed me respect that I appreciated. Before he left, he offered to loan me an electric heater until we have to wait for parts. He provided excellent care and service. I definitely recommend 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

He showed up the same day and immediately diagnosed and repaired the issue. He could have upsold me on replacing expensive parts, but he is super honest and clear about what was needed and just fixed the issue.

Having someone knowledgeable and quick to respond saved me and my family from a cold night. Thank you!

I paid $150 for a diagnostic fee to DHA Mechanical. Jhonny Sibrian from DHA visited my home,…read morecompleted a diagnostic report, and provided an extremely high quote (several hundred dollars more than other quotes I had received). I was upset because I was between jobs, and I wanted to get the work done by them only if their quote matched the other estimates. Jhonny wrote negative remarks about me in his report, even though I paid $150 for it. He then put me on the phone with Paul, and we agreed on $900 (still higher than my other quotes) to repair all the issues identified in Jhonny's diagnostic report. Later, they wanted to create a contract and assured me that all issues from the diagnostic report would be addressed. They required a 50% upfront payment. I expected to pay $450, and when they sent a payment link, I entered $450. However, their payment system charged $463.50 without my consent. I complained to Paul and Sheri, and they said it was standard because they had switched to a new payment system. I disagreed and told them that on the day of repair, I would pay the remaining $436.50 by check. The contract Paul prepared failed to include the flame sensor replacement, even though it was clearly mentioned in the diagnostic report and discussed in detail during Jhonny's visit (since the flame sensor was visibly damaged). I missed this omission when signing the contract. I expected Paul to act in good faith and fix all issues based on the diagnostic report prepared by Jhonny. During and after the repair, the flame sensor issue came up again. Jhonny said it was not in the contract, acknowledged that this was a mistake, and told me Paul would correct it and that he would return to replace it once Paul approved. In good faith, I decided to absorb the earlier transaction fee and paid $450 by check instead of $436.50. After that, Paul avoided me for several weeks by not responding to emails or phone calls. Finally, he emailed me while I was out of town, stating that he did not agree to replace the flame sensor. He was rude and bullying on the phone and hung up on me. ----- UPDATE: A customer grievance BBB complaint was registered and all documentation was submitted to them and awaiting response.

Instead of asking if I had one available, they thought it was appropriate to use my BED to reach areas in my house. Completely unprofessional and disrespectful to someone's home and belongings. To make matters even worse, one of the workers used my restroom and left urine all over the toilet seat and bathroom floor. No attempt to clean it up, no apology, nothing. It's honestly disgusting and beyond disrespectful. If you're working inside someone's home, basic hygiene, manners, and professionalism should be the bare minimum. On top of all that, neither worker was even wearing a company uniform, which made the whole situation feel even more unprofessional and uncomfortable I am absolutely livid over this entire experience and would never recommend this company to anyone.
