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 .

Craig put together a beautiful floor plan for our 380 square-foot mother-in-law unit which included a kitchen, pantry, eat-in area, living room, bedroom, bathroom, and closet. We had a pre-existing empty bonus room which he ripped down to the studs. He added insulation, walls, electrical, gas, water, sewer, AC/heating, windows, ceiling fans, flooring, custom cabinets, appliances, vaulted ceilings, earthquake framing, you name it. The best thing about the entire build is the air gap sealing process he recommended which essentially makes the apartment sound-proof and maintains the interior temperature constant. We've used the AC minimally during the summer because it stays really cool and really cozy in the winter. As a result, we've only seen a minimal increase in our utilities. Craig was a fantastic communicator and VERY detail-oriented. He listened to what we wanted and always kept our budget in mind. The best thing about Craig however, is his integrity. This was a substantial investment for us, but we always felt like he was taking care of us. The process was smooth and painless and there were never any concerns. We've done other home renovations many of which have left a sour taste in our mouth. Craig delivered and met our every standard. Thank you Craig for turning an empty dingy room into my mother-in-law's new home and our favorite hang-out spot!!!! We will not hesitate to use Beckner Contracting and Management for our next project.

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 :-)

We were told the costs clearly, in advance, and the costs were very reasonable. We have an aging gas furnace (that we plan to replace with electric, but want to get a little more time out of), and it decided to work correctly while Aaron was looking at it, which made it a bit tricky for him to diagnose the issue. He told us the two things that were mostly likely causing the problem. We decided to ask him to replace the part that was mostly likely to be the failing part; but it was completely our decision, with no pressure from Aaron. He had the part in his truck, and replaced it quickly, along with the filter (which we had also asked him to replace). This was our first time calling Atlas Heating. Thanks to Aaron's excellent work, we will definitely be calling again, for future maintenance if we keep the furnace for that long, or for his help when we switch to a heat pump.

I would say, they did an excellent job - Starting with Jeremy, who accommodated my schedule for preliminary inspect and gave me a on the spot quote. Elder and the guys did an excellent job in covering up the entire house and finished the job in 2 days. My house had no insulation in the walls- to very less in the attic. After the insulation my Heat as well as Cold is retained inside the house. Heat turns on once in a 24 Hr cycle vs multiple times in an hour previously. If you are thinking of in wall insulation, it's totally worth it. The quote was the most competitive and they were very flexible. I am still closing out the multiple holes in the wall, will take time as i prefer to do it myself- I had plans to paint anyway .

I was initially impressed with what seemed like a thorough and well-considered estimate. It felt…read morelike the team really evaluated my attic and cooling needs. The addition of two QuietCool fans also seemed like a major plus, as I was already familiar with the product and expected it would significantly help with cooling. When it came to the insulation work, I was very pleased. The crew did an excellent job removing the old insulation and installing the new. They worked efficiently, protected my floors well, and ensured that no insulation debris entered the living areas. That part of the job was handled professionally. However, I was less impressed with the radiant barrier installation. This may partly be due to a misunderstanding on my end, as I expected a different type of material, but the end result did not meet my expectations. The biggest issue, unfortunately, was the installation of the fans. At best, it was very poorly executed. The fans are 16" units with 12" duct openings, yet they were installed directly against the gables, which severely restricts airflow. Proper installation should have included a box or shroud to help direct airflow effectively through the fans. Because of this poor airflow, the fans do not cool the attic--in fact, they appear to make things worse. I can actually watch the temperature on the thermostat increase when the fans are turned on. I reached out to my representative multiple times, but the response was disappointing. I was told they could not take the fans back, and when I asked why the attic temperature increases when they are running, I was told there was no explanation and nothing further could be done. As temperatures continue to rise, I'm left frustrated that I spent $1,200 on two fans that perform the opposite of what was promised, with no meaningful support or resolution offered. UPDATE: After posting my initial review, I was contacted by both the project manager and the owner. I reiterated the reasons for my frustration, explaining that my review reflected my honest impression of what I saw as a lack of clear communication and effective management of the project and customer expectations. The project manager apologized for the communication breakdown and asked if I would be open to giving them an opportunity to make things right. A technician was then sent out, and he took the time to fully understand the issue, carefully examine the installation, and make several adjustments to the original work. He believes these changes will help improve airflow in the attic. Since my attic has some unique characteristics, he also provided helpful suggestions for additional ways to improve cooling and airflow--something I feel should have been addressed during the initial planning stage of the project. Whether these changes will result in significant improvement remains to be seen; I'll have a better sense once the weather warms up. I do appreciate the follow-up and the willingness of the project manager to reach out and try to make things right, and I have updated my review accordingly. That said, I want to be clear that the increase in my rating is largely due to the technician and the time he invested in evaluating the full situation, as well as both implementing and proposing thoughtful solutions.

Rafael spent over an hour meticulously documenting every single detail of what needed to be done--he didn't rush through or offer a generic quote. The execution was just as impressive as the inspection. The team performed a full cleanup, replaced contaminated duct insulation , and sanitized the entire area with a DSV solution to remove odors. They sealed every entry point with hardware cloth and steel wool , and the fact that the work comes with a lifetime warranty gives me huge peace of mind.
