Same-day service!

Able to obtain same day service to troubleshoot a hot water issue. Technicians showed up promptly and wore masks, gloves and foot covers. Thoroughly explained three options for resolution in a professional, no pressure manner. I highly recommend this company.

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.

Excellent !

Crew was very efficient and knowledgeable. Replaced HVAC with next day service for first responders. System is working well and installed superbly. Will give it a run for a while to better judge but it is a quality name Lennox system. 10 year parts and service so expect there will be no problems. Good job!

Above & Beyond

Technician Steve, was very thorough in his investigation. Went above what I asked for, we had a black water flood and I was just asking to have the toilet and sink reinstalled. He put his camera through my sewer system to make sure that we were not going to have future issues. He made sure that I was able to see what he saw. It was educational to say the least and he was great at explaining what was in there. Feel very safe using his services and do not feel that he is taking advantage in any way. Highly recommend Steve!!

Very Professional

It was really shocking the amount of damage our pipes had and mr Johnson helped to explain what the issue was... He worked within our budget and created a couple of quotes with positive solutions. We went with the one we felt was necessary and he worked quickly getting that issue resolved. Very professional and knowledgeable.

I had Mainstream come out for an annual inspection of my hot water heater. After the inspection, it was determined that the water heater needs to be replaced. The technician, Cory, was very professional and made all of the necessary arrangements. Later the same day, Shane came out and replaced the water heater. Shane was very professional and knowledgeable. I am very pleased with the employees and the work that was completed by Mainstream.

Very Happy

We had them come out for a yearly maintenance on our water heater. They were thorough and gave good recommendations for continued maintenance and use. We also had them install a new furnace and air conditioning unit. They were very quick and efficient. All the crew members were courteous and respectful of our home. I am very happy to recommend them to others.

Our water heater was making noises it shouldn’t. Chandler was professional and very knowledgeable. He educated us on the issues and answered all of our questions. I recommend this company.
