What Our Customers Say

They were wonderful. The guys will only have one appointment at a time so they get done in a matter of days. We had our entire garage rewired (the prior owner had faulty wiring to the garage and basically only the door worked) and they got it done in a matter of 3 and a half days. Would have been 3 but waiting on Avista held them up. I have nothing bad to say about this company.

Very reasonably priced. Very professionally. Quick and Prompt.....

Good job. Professional.

Nice, very professional.

The installation guys were above 5 stars very helpful in explaining everything.. David antaya was also 5+ star's he went over everything he did.. Mainstream are very professional people i made the right choice!!!

Brent and Duane made a very bad situation so much better. Fixing a situation that another company left incomplete and doing it after hours to boot. Great experience we will be returning customers.

Also had some other work done. they were great explained the work in clear language and gave me pricing options to choose from. cleaned up after all the work was done. will use this company exclusively from now on when I have future work done. highly recommend

Got my electrical problem troubleshot and fixed. Even found a way to hide the repair so it appeared as before. Left my house just as it was before, clean work area.

The job is scheduled for Friday. John was very informed, knew what, where and how to examine old ac. Diagnosis was right on. We look forward to having new system and knowing it will be supported by local company.

The quickest service, John was kind and sweet to our dog. He ran out and got the part we needed and fixed it immediately! Highly recommend!!

James was incredibly personable and communicative. He shared what he was doing each step of the way. I appreciated his professionalism with the job he did in my home.

Prompt response and very knowledgeable. The technician, Alex, was able to walk me through the repairs and how my furnace and a/c systems work together. Very transparent company and excited for our service work to take place. They provide quality service and great piece of mind.

Very professional and friendly.

Professional and took time to explain everything and honest. Didn’t know there were still honest plumbers around anymore. And affordable. Everyone else wanted over $100 just to come to the house.

Came out in 2 days and we have AC again! Great job and had everything up and running quickly!

Were able to address the problem with the AC the day after I called. Technician was on time, quickly identified the problem, and was able to fix it immediately. MUCH appreciated as we were in a heat wave

Very efficient and polite! I would like him to be sent again!

My air conditioner went out. Mainstream was at my house in 45 minutes. Really nice technician and will use them from now on.

Brent and Ryan added a regulator to control the water pressure in our house. They gave us an estimate before starting the job and explained the work to be done. They were very professional and completed the job quickly. I would use Mainstream again.
