TESTIMONIAL
What Our Customers Say!
I couldn’t be more pleased with my experience with OSO Holdings Group! Not only did they install a top-of-the-line solar system, but they also replaced my roof and upgraded my HVAC system. The team was professional, knowledgeable, and efficient throughout the entire process. They specialize in whole-house efficiency, and it really shows in the quality of their work. They walked me through every step, from the solar installation to the new roof and HVAC, and answered all my questions. The installation was quick and seamless, and they left my property clean and tidy. Since everything was completed, I’ve seen a significant reduction in my energy bills and feel great knowing my home is more energy-efficient and sustainable. I highly recommend OSO Holdings Group for anyone considering solar energy, roof replacement, or HVAC upgrades!

Highly recommend OSO Holdings Group. Dazia is extremely helpful and informative; she will answer every text or call to resolve any issues or questions you have. Most importantly, she genuinely cares that you are taken care of both during and after your system is installed. I personally like that all the communication is with the owner directly.

My family and I are very content with our energy-efficient windows, air conditioner, and new roof. Every day I know it was a great investment financially and the best investment so far for our home. Dazia came into our life and mentioned that the roof and air conditioner were a possibility. It was unbelievable that everything she said was true …the right time, and in no time it was done. Dazia is definitely a woman of her word. It was a win-win. I feel confident in my choice to do this, especially with Dazia at our side. I have recommended her quality of business to my sister and my two nephews, basically my whole family that are homeowners.
