Very personable and patient!

Both technicians that came to our home were great! They were very personable, and very patient. My mother in-law has a hard time with her English, as it is her second language, but they were both very patient with her, and made sure she understood everything that needed to be done. On their customer service alone I would recommend this company. We live in an old 1980's trailer which made it hard to find parts needed to fix our heating system, but they did all the research they could to try and find the parts needed. I am so glad I decided to call Mainstream Electric and will continue to use their services in the future.

Great seasonal service!

Great seasonal service today on our furnace and air handler/AC unit. Matt Miller did a very courteous and professional job describing all that he was doing and did and made additional recommendations on future service and care. He was very knowledgeable and had great interpersonal skills. We have used Mainstream for other projects as well and have always been satisfied with the work performed. I can say with honesty that they have not always been the cheapest, but they have always been the best. 'Good service is not cheap and cheap service is not good.' If you ever need a plumber, electrician or HVAC specialist, I highly recommend Mainstream.

Cody was respectful, personable, courteous, answered all our questions we had during his visit, knowledgeable. Cody helped us get in touch of the appropriate people, to finance the work that our home needs. He helped get the work scheduled so that we wont need to wait longer to get the work taken care of.
