We had our HVAC ductwork cleaned and sanitized. This is a 40yr old system that has never been cleaned before. Process was very interesting to watch and quite involved taking in excess of 3 hrs. All went well, before and after pictures showed quite a difference. Happy we had it done. OHA did not disappoint!

They were able to come out the same day that I called and resolved the issue with our heater, even though I didn't get them called until after 1pm!! Steve was an outstanding tech and they will DEFINITELY be who we call again if we have any other issues! This time we had Jeremiah and he was just as outstanding as the last guy!

Bernie from OHA Heating did a thorough job assessing the problem with my HVAC unit. He explained everything clearly and gave me several options for repair and replacement.

Great customer service. We were seen a few hours after our initial call. The first company we had come out rushed and made the situation. Worse. We called OHA home service and Bernie was amazing! So helpful and informative. He taught us so much we never knew and helped us. He is honest, thorough and efficient and now we can rest easy knowing our baby doesnt have to sleep in 80 degree temperature. I wish more customer service was as thorough as Bernie and this company.
