Best service

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!

Great Service

We had some plumbing work done by Mainstream. The plumber (Sam) they sent out was GREAT. He listened to what we wanted done; gave us advice about things that could become issues and was very conscientious. We took his advice about our 15+ year old water heater and replaced it. My husband raves about how great it is to have really hot water. We plan to have Mainstream do work for us in the future.

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!!

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.
