We met with Tad to discuss going solar. We are very impressed with his knowledge, professionalism, and friendly manner. We are excited to complete installation and do our part in reducing our "footprint".

I gave 3 star initially, sense my home isn't not producing near the power as predicted off their graph they show. Even though a lot of it is due to Mother Nature and is out of True home control. Ryan my sales rep has been awesome helping through the problem and even though they do not need to they are adding 4 panels at no charge to the home to help produces more energy and send me a credit for my low production months.

I am having these panels placed on my home and so far I am very impressed with TruHome. The sales rep, Ryan, was kind and not pushy. The customer service has been excellent this far. I am looking forward to getting started on this project.

We were extremely impressed with the outstanding and professional advice given to us. The total transparency of this company and the highest level of customer service we have seen in a very long time. We absolutely recommend to anyone reading this review, that Tru Home Pros experience was worth the time and at this time we are beyond satisfied.
