HVAC, Electrical, Plumbing
"Anytime when I need any electrical a plumbing problems I will hire them from now on and nobody else. When I called about my hot water heater my hose was leaking and they were out the next day early in the morning. It's a family-owned business and they treat you like family and the prices are great and they're honest. So if you need any Plumbing HVAC and electrical give Shafer's mechanical a call."

"After less than 2 weeks in our new house, the sewer backed up into our finished basement. It was a huge mess, and it was so backed up we couldnâ t use our water for the whole weekend. We looked up local sewer companies, and Pronto said they could come out and give free quotes, so Chris stopped out and diagnosed what was going on. We actually needed all new sewer pipes due to the neglect of the previous homeowners. All the guys that came out were prompt, friendly and professional! They were so understanding and willing to do whatever they could to fix this quickly and properly. When inherited with an unfortunate situation, they were just so nice about the situation we were in. Chris and Seth were two of the guys we interacted with a lot who were just seriously so nice. We also interacted with Teddy, Connor, and Zimmy who were also very kind! Once we realized there was another separate problem a few days after the sewer pipes were fixed, I called Pronto back for their services again. I got a call back right after from the Vice President, John Gribble, who has been so amazing to work with! He dropped off back up heaters at our house due to having no back up heat, and had people come out ASAP to replace our HVAC system. Thank you John!!!!!! Tom Snavely and crew who replaced the HVAC were also so kind too! I had my daughter and nephew home with me the day the replaced the HVAC system, and every time they came up the stairs and passed the kids, they would smile and wave at them and the kids loved it! I appreciate them being so kind to the kiddos too! Literally every single person from Pronto that we interacted with has been nothing short of amazing. EXCELLENT customer service! They now have a customer for life with us!!!! If you want prompt, efficient service with a company that values superior customer service- Pronto is it!!!!!"
