While I wasn’t excited to be in need of an all-new HVAC system for my 1960s-built home, the team at C.M. Mose reallyyyy took great care of me from start to finish… from Amy on the phone for the (dreaded) appointment; an experienced and super helpful repair team (sorry! I forgot their names- my son met them); then (Amy’s husband!) Jason guiding me through the entire process starting with quotes, and giving me needed reminders (like I needed to sign one more form for the financing to be fully submitted); to the prompt, helpful, courteous and confident installation team of Hayden and Justin. Seriously. Everyone I worked with was professional, understanding, easy to work with and highly competent. This company is doing things right, and I appreciate that, especially with such a sudden/unwanted purchase. Thanks, everyone, for making it a positive experience. 🙏🏼

DARIN was super helpful and located and fixed our bad outlet in about an hour, I was super impressed and appreciate his expertise. It turned out the problem wasn't even where we thought it was, but he figured out how the circuits were connected and fixed the wiring, and didn't try to oversell services, and also fixed the labeling in our breaker box while he was at it. I feel like I have been well taken care of by a trustworthy electrician and feel confident in his work and the condition of my home. Thank you, cm Mose!

Chris did an amazing job! He’s thorough, friendly, professional and is very respectful. He explains everything and takes pictures of every step he takes. I would recommend Chris any time! C.M. Mose is lucky to have such a knowledgeable, kind and respectful employee. Treat him well, good...
Chris did an amazing job! He’s thorough, friendly, professional and is very respectful. He explains everything and takes pictures of every step he takes. I would recommend Chris any time! C.M. Mose is lucky to have such a knowledgeable, kind and respectful employee. Treat him well, good employees that treat the company like it’s their own are hard to come by. All about the customer and his work that he can do for the customer!

We had our 50 year old electrical panel replaced and I can’t say enough good things about this company and Darrin. He was professional, knowledgeable and went above and beyond- he even sprayed a wasp nest he found in our backyard. You don’t find service like that these days. I highly recommend them.
CM Mose never disappoints. You can be sure of excellent service, because of Chris’ attention to customer service. He calls or texts with his ETA, wears shoe covers, and explains everything he’s completed. I appreciate that he treats me with respect and gives me piece of mind about the...
CM Mose never disappoints. You can be sure of excellent service, because of Chris’ attention to customer service. He calls or texts with his ETA, wears shoe covers, and explains everything he’s completed. I appreciate that he treats me with respect and gives me piece of mind about the condition of my HVAC, generator, or plumbing issues. Thank you!

I recently had four light fixtures installed, and the experience was fantastic from start to finish. The electrician arrived on time, worked efficiently, and made sure everything was installed safely and exactly how I wanted. The quality of the work was excellent, and they cleaned up the area afterward, which I really appreciated. Professional, friendly, and reliable—couldn’t ask for better service. I will definitely be using them again for future electrical projects!

Very professional guys. As a local mechanic guy I like supporting other local businesses. I will definitely call them again!
Patrick and the rest of the CM Mose crew were amazing! They installed our Generac whole house generator faster than we expected. They were very thorough and found an issue we need to address in the future. The installation looks very professional and like it was done during the build process....
