He was able to diagnose the problem and repair it very quickly with parts he had on hand. It's been running smoothly for the last 3 months and we haven't had a problem since.

Thankfully Machi Mechanical came to the rescue and got everything figured out for us. Machi quickly identified that the system that was installed by the other company was completely wrong and would never draft correctly due to the type of ventilation system existing in our home. We decided to go with a tankless system after hearing all of the benefits. Steve and Kevin worked non stop to get the job done right before Christmas. The attention to detail performed on this job is mesmerizing. There isn't one piece of the system that isn't level or measured perfectly. All of the soldering is flawless. They came with the promise of having hot water by the end of the day that they began the job and Machi Mechanical did just that. I will be a forever customer and I highly recommend you do the same.

I rely on my fellow Yelpers to give me honest, unbiased reviews of local businesses. Most of my…read morereviews and searches are about food, but occasionally I have a need for another type of business and this is the first place I turn. You all led me to this small, local business and you were spot-on, so I am paying it forward by adding my review! My family had our pipes freeze in the winter storm this Christmas. Friday, it was the cold water pipe, which took seven hours of work to unfreeze. We thought we were in the clear and counted our blessings as we kept the cold water running overnight Friday -- only to discover Saturday around noon that the hot water pipe was now frozen solid. Twelve straight hours of effort with hair dryers, space heaters, boiling water pots, heating pad wraps and everything else we could think of did not work and we went to sleep Christmas Eve defeated, wondering how we were hosting the rest of my family on Christmas with no hot water, dishwasher, etc. (Our efforts did eventually pay off with the hot water coming on at 8 a.m. Christmas morning and no pipes bursting. So grateful.) During this nightmare I called a number of plumbers who list themselves as emergency 24/7 plumbers, but only Gary from Brickhaas called back. He called during the span of time that I thought everything was under control, but I asked if we could be booked for later in the week to unclog a bathroom drain I've had a problem with lately. Glad I booked them as, after the pipes thawed, the under sink drain was leaking slightly so Dominic was able to take a look at both of these things today. He called with a 20-minute heads up on his arrival, efficiently took care of the clogged sink and an aerator that was limiting water flow, installed a new kitchen sink trap assembly (which he said I could honestly take or leave; I appreciated the honesty but opted to replace for my own peace of mind), and offered solid advice about what we might do if plans to better insulate those water pipes in the future didn't work out re: rerouting the pipes from their current, poor location. He was highly knowledgeable, didn't hard sell anything and I absolutely got his card as I'll be calling them for future plumbing needs. Yelp comes through, as usual!

Calfo installed a gas furnace for me through the weatherization program. At first the air wouldn't…read morework, the ducts were completely blown apart, I called them back, they came out 4 days later and taped it all together. My stove and hot water heater were not working properly so I called another company out to check it. There were gas leaks. The leaks were small, but I prefer no gas leaks. There had been 2 inspectors in prior and there were no leaks prior to the furnace installation. The lines were old though. They said all the line needed fixed (this is true) but needed to submit a estimate to make sure they would get paid to fix it. So I sat and waited 2 weeks with a few gas leaks until they came back. Ultimately I have a 100% efficient furnace and all new gas pipes that are working properly. I got this through action housing, so even though I had to make a dozen calls i consider myself pretty lucky. Even though I complained and they had to come out 4 times for what was a 1 trip job, everyone was courteous and respectful. Both myself and my property were treated with respect. Ultimately if you aren't up for a lot of follow up avoid like the plauge.
