I hired this company to do the work on my house that was recommended in a home energy assessment…read morecompleted last year. Initially Alex Minaboo, the owner, came to look the job over and in that visit recommended replacing all the heating ducts in the house. He tried to sell me a heat pump system which I did not want to do since the existing furnace is only three years old. There was nothing in the home energy assessment report indicating I needed to replace the furnace or the ducts. A few weeks later, the foreman (I think that is his role) came by to assess the job, and said he did not think the ducts needed to be replaced as they were still quite new. I opted to not replace the ducts but to proceed with the air sealing of the heating system that was recommended in the home energy assessment. Alex later said the air sealing could cause a problem for the furnace, which he said was too large for this size house. He suggested that adding an additional heat register might mitigate a potential problem with rapid cycling, and I opted to do this. In the course of All Things Good sealing the heating ducts and adding the new register, the blower on the furnace stopped working. Alex deflected and denied responsibility for his company causing the problem, disparaged another company that had installed the furnace, and argued that his company could not be held responsible for damages when something breaks in an old house while they are working on it, referring me to a clause in their contract. To fix the furnace, All Things Good charged $1200.00 in labor costs (for a job that took no more than 2 hours on site) and the blower was about $700 more). I have always thought "if you break it, you fix it" and I was floored by how this was being handled, but since I do not know HVAC systems and could not in good conscience argue that I was certain the breakdown was caused by their work, I proposed we split the bill for fixing the furnace. My offer was refused. Alex then had the gall to argue he was already giving me a discount on labor costs, and threatened that if I did not pay he would put a lien on my house. I paid the bill because it was not worth my time to fight with All Things Good. I see a number of positive reviews here and at least one that is like mine. My experience was very unsatisfactory and I will certainly never use this company again.

The team was professional and fast and they went above and beyond in explaining the water heater and the app. They even installed a new light in my basement so they could complete the work, which is helpful to me as well. And then they came back and installed some additional insulation to mute the water heater noise. The office staff was also excellent and very responsive and helped me get all the rebates I was eligible for. Look no further, All Things Good is the team you need .

Since it wasn't a major issue, we accepted it as a minor quirk. During this year's regular maintenance, technician Denali Boyd noticed this issue and offered to fix it. Denali visited twice, consulted with experts, replaced the circuit board, and made sure everything worked flawlessly. He genuinely embodies the saying: "Winners find solutions." Thanks to Denali's persistence and professionalism, our heater is finally working as it should. Dedicated professionals like him build a company's great reputation, and we are deeply grateful for his dedication. He earned Hassler Heating another well-deserved 5-star review!

We bought in a mid-century house whose furnace is located on the roof . It is a common location for…read morethis type of house, but -needless to say- it is not easy to replace that furnace when the need comes. We decided to hire ATLAS for the job: the furnace was old, and the original roof ducting did a lousy job distributing the heat throughout the house. I was always cold even when the heat was "blasting". ATLAS did a thorough and patient analysis of our old system. They decided to double up the ducts to provide more air flow, and they also organized the flow inside the ducts: it worked. Frankly, the final cost was reasonable, considering the benefits I am getting from it. I particularly recommend Nick and Scott who supervised the project: they really looked into the project, then fixed the problem. Plus: the work was clean, and the communication great all along. Happy customer :-)

What I absolutely love is how easy she makes it to make changes. I think the task of going "green" in your home can seem daunting but with her report with links to everything makes it SO easy!! Every two weeks (i.e. payday) I go into the document and purchase a couple more items for the house and get so excited throwing away / recycling or finding a new use for plastic items. And honestly, a lot of the changes we have made so far are going to save us money! The new toilet paper delivery we have, the new all natural house hold clearer... and the UNpaper towels I'm going to buy... and she's not sponsored by anyone, just finds good companies for her clients.
