    Hiram did a fantastic job installing 3 Mitsubishi mini splits into our home. He was able to give us…read moresolid recommendations based on our use cases (huge downstairs space, smaller upstairs spaces) and was very communicative and professional throughout the entire process. For instance, at one point during the install he realized a drain pipe needed to be run through an existing bedroom closet. There were 2 options with regards to how to install the pipe and he consulted me explaining the pros and cons of each before doing the work. I thought this was great as opposed to just doing the work one way and not telling us. It is extremely obvious that he cares about doing good work and ensuring the end result is something both he and the homeowner can be proud of. I would highly recommend Hiram and would definitely ask for his help again in the future!

    Downgrading to two stars. I still stand by the initial review (hence the second star) - Hiram did…read morerespond promptly when we were somewhat desperate and cobbled something together that seemed to work. Until it didn't. A few months after the install, all units stopped working after a storm. After months of back-and-forth, he finally realized -- through trial and error - that the boards of all units are fried and need to be replaced. His best guess? "Your condenser probably got hit by lightning" (condenser is on the roof, but we have a lightning rod; there's been no indication otherwise that the building got hit by lightning). A few weeks pass by, some more rain, same thing happens again. Replace all the boards again. "Your condenser keeps getting hit by lightning". A few more weeks, same thing again. By this point a year has passed after the install and we have spent most of that year with our $30,000 mini splits completely non-functional. It's also pretty clear that it's an issue with the install and nothing to do with imaginary lighting. Then Hiram has the audacity to inform us that our one-year contract has expired and now we have to start paying him for repairs, even though this issue started while we were still under contract and has persisted for months because Hiram has simply been unable to fix it. At this point, I was willing to just move on and hire a more competent contractor to fix the issue. That's when we started having other contractors look at the system and realized what a horrendous job Hiram had done. Most egregiously, the wiring had been done incorrectly, creating a huge FIRE HAZARD and potentially exposing our entire household and our neighbors to significant PROPERTY DAMAGE and potentially loss of life. See attached screenshot from assessment. In addition, there have been numerous other issues with the install: - Water repeatedly leaking from the heat pumps into our house when it rains - Exposed lines - Condenser freely standing on the roof, not affixed to anything - Slopily taped line set covers - Sloppily installed water pumps - Overall poor craftsmanship See attached images. We are currently addressing the issues one by one with multiple contractors. To be clear, WE ARE STILL WITHOUT A/C TWO YEARS AFTER THE INSTALL. We only really had it working for ~6 months. Unclear if it's even salvageable. In hindsight, there were also multiple red flags that we overlooked in the beginning, but should have given us pause: - Hiram did not know that Fujitsu is Japanese. How can you not know the country of origin of your main supplier? - He drilled through brick in our apartment without any precautions, filling our entire house with brick dust. He had no idea it's hazardous to breathe in, he didn't even put a mask on himself. Our entire condo was covered in brick dust. We had a 1-year-old kid at the time. - He did not clean up properly after himself, our son ended up with a glass shard in his foot Overall, I would not recommend Hiram's services to anyone. He is polite and responsive, but when push comes to shove, his work is not just poor quality, but outright dangerous. Hiram, before you post some sob response like "I'm just trying to feed my family man", consider this - you put my family, and my neighbors' families at risk because of your incompetence. And you ultimately refused to take responsibility. You should be ashamed of your work and of your character. (Responding to Hiram's response) -- there were no "stories", I was just trying to help you figure out what could be causing this. Yes, you definitely blamed lightning multiple times. I had multiple contractors take a look at it and say the same things. This is not "Mother Nature". This is just a plain bad job.

    I need a 2nd mini split installed at my home. Received 3 estimates, all came back roughly in the…read moresame price range. 128 quoted the OEM Mitsubishi unit that I was looking for, (the others did not) along with handling all the permits & electrical needs. Their price also included a 3 year service plan. The install was scheduled 3 days after I accepted the quote, others were scheduling 2-3 weeks out. On the day of the installation, the 128 crew arrived right on time, calling ahead to let me know they were on the way. They showed up with a four man crew, 2 installers for the mini-split and 2 electricians. The work was pristine, the wiring was neat, the unit was placed on a pad and looks great! The crew (Paul, Nedim, Nick & Connor) was extremely professional and curtious. The work was completed by 3pm same day. I am 100% pleased with the work and will be using them going forward for all my HVAC needs.

Ryan was great, tried to keep my carpets/bathroom clean as much as possible and was patient in discussing my options and answering my questions. Surprisingly was able to get an appointment for install on Monday. Jared was also great. Definitely appreciate the small details and concerns to keep the carpet clean like hand carrying both the old and new water heater up 2 flights of stairs. Between the quick response/scheduling time, clean workmanship, and fine attention to detail, happy to say the leaking water heater experience felt less chaotic with 128's help! Total turnaround time, Friday 11pm to Monday 4pm hot water up and running!!

    We just recently moved and didn't know of any reliable Heating service. I looked up Gas Furnace…read moreRepairs Service and Andrew Plumbing & Heating was one of them almost at the bottom of the list. After a few attempts of calling other companies w/answering machines, I dialed Andrew Plumbing. Low & behold Andrew answered. I told him my issue and he can out to my house within hours. He thought he found the problem which were the relay and the over flow charging $330.00. After another additional 900$'s the problem was not fixed and the issue remained. I decided not to waste any more of my money for fear I would be replacing the entire furnace in unneeded parts. I had asked him if the thermostats had to be on the same temperature and his response was "no". We have two thermostats, one upstairs and one downstairs. Both are on the same base board heat system, using the same furnace. If I put the thermostats on the same temperature the system will work. But if one is on 68 and the other on 74, it will shut completely off and come on many hours later for a while and do the same again. So after dishing out $1,230.00 we just keep the thermostats on the same temperature.

    DO NOT hire this plumbing service. First of all, they sent someone that couldn't give us a…read morequote...he had to call and ask his boss from his van. Took several minutes...and he came back in the house to tell that the three jobs (a leaky shower, an install of a faucet I had purchased and a replacement of a black kitchen sink sprayer) would total approximately $1,000. They charged an $85 fee to come out, but said they would take it off the total payment. If you look at their website it states that they take all credit cards (MC/Visa/AE/Discover)..yet when I said go ahead and I handed him a credit card, he asked me if I had financial problems since I couldn't pay with cash or a check. I wrote him a check for $85 and he was coming back today to do the kitchen sprayer and install of bathroom faucet. I told him two weeks for the shower as I had to budget for it. At the time that they were expected to be here today, we got a call saying that the $85 could not be taken off these smaller jobs, but not until we scheduled the over $600 job quoted for the shower leak. This place is a rip off, and don't believe their webpage..it lies! They DO NOT take credit cards! I think it must be against the law to declare something on your website and then not accept it.
