"This pro arrived to the job about an hour and a half early than scheduled time and gave his honest professional opinion on what my problem was regarding a leaky toilet. He also gave me the option to totally remove it it but based on his professional opinion, the project seemed to only require replacing a leaking water supply line which was less work to replace. I appreciated having the option for repair but trusted his professional opinion. To date, the repair appears to have remedied the leak. Will continue to monitor the ceiling below for a couple of weeks to see if everything is fixed. So far so good! I will be calling him backhand would recommend for hire!"

"Kyle and Marc were on time, professional and very knowledgeable. They understood what we are looking to do and were able to provide quotes immediately. We expect that we will contract with them for a new hot water heater or a tankless hot water heater. I expect that their work is as exemplary as their representatives are."

"Great. They called to make appointment. Called to let me know they would be there in 15 minutes, Were on time, professional, efficient. Due to house and plumbing being 50+ years old, they did have to find a part at the supply store but came right back and finished the job. They advised us to get the lower shut off valve fixed in the future and sent us an estimate. Very pleased and would recommend them to my friends.$199"

"Total Mechanical Systems went the extra mile. In one week they fixed my water heater and the igniter on my furnace. They were prompt and did exactly what they said. Their service techs are knowledgeable, and when the tech who came to my house couldn't diagnose the problem, he called in a more seasoned tech. They both worked on it for some time but only charged me the $99 diagnostic fee. Well done!"
