DynaTherm was listed on the Nest website as a recommended installer, so I gave them a call. Dave was friendly, professional and knowledgeable. He showed up exactly when he said he would and took the time to walk my 80-year old mom through the basic operational steps of her new high-tech thermostat. From start to finish, it was a great experience. I would highly recommend Dave and look forward to using his services at some point in the future when we have the need at our house. Thanks Dave!

Nelson was recommended by a friend and I couldn't be happier with the installation. He and his assistant arrived on time and finished the job in one day. Not only did he install the heater but he ran an extra wire so that I could use the fan feature only to circulate air in the summertime. He also installed a flue because the person who had installed my old heater hadn't done so. Now, I have a new heater with a properly installed flue, the right heater for my home, a fan feature, and a new programmable thermostat for a reasonable price, including hauling away the old heater. NK Heating will be my go to for any future furnace repairs or maintenance. Nelson is not only an excellent technician, but he's also a really nice guy!

Our previous maintenance visit was Sep 2022. After being dormant for the spring/summer months we were pleased to have the floor heaters start the first time. We plan to schedule a maintenance visit in the next few months. As another reviewer stated, it is challenging to find an experienced HVAC professional to competently repair and keep older equipment in running/safe condition. Chris is very knowledgeable, efficient, resourceful/timely with locating repair parts, and we really appreciate his ability to clearly explain next step repairs/costs to schedule the work.

Chris responded to my quote request within minutes and came over to do an estimate the next day. Chris was really professional and helped answer my countless questions.

When the day came around, Chris and his team were actually an hour early. They finished right on time and the job was impeccable. Really pleased that I was able to meet Chris and am grateful for their service! Will hit them up when I need an air con system.

I rarely write reviews, but my experience with Efficient HVAC was so far beyond my expectations…read morethat I wanted to recognize a company that truly deserves it. I called Gabe because I knew my aging AC system needed to be replaced. I had been hearing about heat pump systems that replace both your air conditioner and furnace, especially how energy-efficient they can be for homes with solar, but I wasn't sure if it was the right choice. Gabe took the time to explain how the systems work, answered all of my questions, and helped me weigh my options. There was absolutely no sales pressure--just honest, knowledgeable advice. I received quotes from three other companies, and Efficient HVAC offered the best value without cutting corners. From start to finish, everything went exactly as promised. Gabe communicated clearly, set realistic expectations, and delivered on every one of them. The installation was smooth, and his team was professional, courteous, and highly skilled. I've had my new heat pump system for a few months now, and I couldn't be happier. It's incredibly quiet, keeps my home cooler and more comfortable than my old system, and my energy usage has actually gone down. I'm especially looking forward to seeing the savings this winter now that I won't be relying on gas heat. If you're looking for an honest company that does quality work, stands behind its word, and genuinely puts the customer first, I highly recommend Gabe and the entire Efficient HVAC team.

It was a pleasure working with him, and I highly recommend Gabriel to anyone looking for an honest, skilled, and dependable HVAC technician. Five stars all the way!

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 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 .

Daniel stood hands above all other estimators in his consultation and he suggested relocation of furnace to crawl space after learning of our plans to remodel basement to free up valuable floor space for development. He also suggested zoned system to allow future tenant to control heat independently from main floor. Pricing was very competitive and working with the team was straightforward and professional. They showed up on time, consulted with us regularly on progress and left work area spotless. Daniel and team also worked closely with us throughout the install process to accommodate our needs to minimize any potential rework once our remodeling took place. End result is toasty home that is much more comfortable with more even heating at lower cost and we have an additional 100ft for our studio remodel. Thanks Daniel and Richard!
