"woke up at 4 am for work turned on the shower, no hot water, went down to the kitchen, no hot water, went dreading heading to the basement. Yep the water heater was leaking. At least a 6 yr water heater lasted 9. Called around 5:00 am. Got their digital secretary, said a man named John would call, within 15 mins he called, told me to call the office at 7:30, I was waiting until 7:45 (have to give people time to get their coffee and set up their space) Susan called at 7:30. Made an appointment, they would be at my house between 10 am and 12 am. just before 10 am I get a text John is in the hood, 5 mins later John is at the door. Took him and his guy 1 hr to replace my heater. Great Friendly service."

"Fixed two shower problems. One was linking and the other didn’t have enough hot water pressure. Jason was able to get a 29 year old shower stem unit replaced saving me hundreds of dollars on one bathroom. The second bathroom needed a water pressure adjustment again saving me hundreds of dollars."

"Huge shout out to the crew at Main Stream Mechanical. Eric came out, reviewed my current system, and gave me his recommendation for replacing my furnace and hot water heater with a new, energy efficient furnace/hot water heater. Brenda, as always, was a pleasure to deal with. Answered all my emails and calls promptly and gave me all the information I needed in a timely manner. She even went out of her way to register my new furnace and provide me with all the information I needed to apply for my rebate! Nick and Marcus did a great job installing my new furnace/hot water heater. Both were very friendly and professional. Nick answered all my questions, gave me a “tutorial” on the emergency shut off procedure for my new furnace, and did a fantastic job re-plumbing all the lines needed for the install. I highly recommend Main Stream Mechanical for all your HVAC needs."

"Dan is great. Very responsive and reasonable rates. I have had him back to perform other improvements. Would highly recommend."

No "up sell" like some of the others out there. Just honest and professional service."
