We have the Dandelion geothermal heat pump installed for about a year. We are very happy with the system and it has worked reliably through cold months (heating) and heat waves (cooling) and provided significant savings and improved comfort. Full Story: More than 2 years ago we had to move to a bigger house (over 2500 sq. ft.) and the high heating/cooling cost was a big concern for us. The house had more than 50 years old oil boiler. It was falling apart and nobody wanted to repair it. It couldn't heat the house properly on cold days. That first winter we paid more than 6000$ for heating oil. The central cooling system was about 15 years old but it was in terrible condition and according to a few companies we contacted the system was beyond repair and required full replacement. Naturally we started looking for a replacement for our heating and cooling. Our first idea was to save money and just get a new oil boiler and AC system. We were shocked when we learned that the cheapest oil boiler will run us at about 15k and the AC system at around 10k (we got quotes from multiple local companies but all the quotes were in the 20-30k range for heating+AC). We started looking at other options and eventually after plenty of research done we stopped on Dandelion. Their quote after all incentives matched the boiler+AC and regular heat pump price (for our size house with our number of rooms we needed 2 regular heat pumps). Given that a geothermal heat pump is a more efficient, long lasting and low maintenance solution compared to all other options we went ahead with the project. Our Dandelion representative was honest and direct which we liked. He made it very clear from the very beginning that in order to allow the low price the Dandelion system will not work for all houses (our project can be rejected after initial inspection) and it takes on average a year to finish all stages of the project. For our specific case, after initial inspection, Dandelion concluded that they will not be able to use existing ductwork in attic (due to very high ceilings in the house which would affect heating) and they won't be able to install new ductwork in basement since it is not straightforward due to house's layout. We were given an option to find an independent ductwork installer to do the ductwork in accordance with Dandelion specification. After some consideration we decided to go ahead (since the ductwork in the attic was in such terrible condition that it required replacement anyway). The whole installation process (design, permit, drilling, tranching, unit installation) took about 9 months, we signed the final contract in December/January and the unit was installed in September. After installation it took a while to close the permit due to slow response from our town but luckily for us we could start using the system right away. I would say the whole process from contract signing to closed permit took around a year. We didn't have any major issues during the installation process, communication, scheduling and actual work were on top notch level. Moreover, we had to do a lot of different updates in the house over the first few years and I would say the Dandelion team was one of the most professional teams we had. The system itself is night and day compared to our old boiler. We were surprised how well the system keeps our house warm. While the boiler struggled to keep our biggest room even at 65 during coldest days the geothermal system kept 71 degrees reliably across the whole house even on coldest nights. Another big benefit for us was the fact that the Dandelion system doesn't dry air as much as the boiler. With the old boiler I had terrible xerosis every winter. With the new system I didn't have any issues, average humidity over winter in the house was about 50%. Unfortunately I cannot compare cooling since our old system didn't work when we moved in but the Dandelion system holds 73 degrees in our house reliably even during heat waves. Now in terms of money saving. It is hard to compare apples to apples since along the way we installed attic insulation (it's actually of the requirements for the geothermal, since it works great only if you have well insulated house) and installed heat pump water heater for hot water (it used to be heated by the boiler). As I have mentioned before, we spent around 6000$ (4 zones, 69F during day, 65F at night) for heating with an oil boiler for the heating season. For Dandelion, during the past heating season we paid around 1316$ (71F across the house day and night) for the whole season. Even given our insulation improvement and minus water heater the difference is staggering. Few words about service calls. We had a minor leak shortly after installation and the issue was fixed a few hours after we emailed them. read more

I converted my 1955 Cape Cod style home from natural gas to ground source (geothermal) heat pumps in 2023. I had done a bunch a market research and had gotten quotes from (3) different HVAC contractors. Dandelion Energy was the stand out solution for multiple reasons. 1. Thoughtful and detailed analysis on the front end. I found out that not every home is an easy retrofit (although I was lucky my home was). Dandelion's attention to detail gave me comfort that the solution was being truly custom designed for our home. 2. Vertical Integration of the well drilling. The other 2 contractors were planning out sub-contracting out the well drilling. This would have added additional cost and complexity and would have made me work as a project manager. Dandelion owns their drills so the drilling was just part of the overall installation. 3. Utility Rebates - Where I live in MA there is a program from "MassSave" in which the utility provides $15,000 incentive for a whole home HVAC replacement. Again the other contractors told me that I would be responsible for filing for and collecting this incentive. Not Dandelion! They took the $15,000 directly off the purchase price and handled all the paperwork. It has been nearly a year since the installation, the new systems are super quiet and provide a great even heating and cooling for our home. One last comment, I did a lot of research on Air Source vs Ground Source heat pumps and had conversations with (2) neighbors also relacing their outdated HVAC systems. The neighbors went will air source heat pumps because it appeared on face value to be less expensive (up front purchase price). In hind sight I was able to show them that with the state and Federal Tax credits (30% for Geothermal / 0% for Air Source heat pumps) that my system cost less up front AND it is cost far less to operate as Geothermal is pulling a constant 55 degrees from the ground whereas it has been below freezing in MA for most of January and February and although their Air Source systems were able to heat their homes the used a lot more energy to do so. read more

Bought a house with 40 year old furnace and Central AC Condenser, so knew we would need a replacement soon. Had some foresight that natural gas prices were going to go up, and they almost DOUBLED over the past year...so glad we got this installed! Getting geothermal is a longer process, split into 3 parts: 1.) Drilling - Crew showed up after permitting and were able to get the drilling done in 2 days. Were very professional and we altered to the drill location in the field to make sure the rig could safely core out. The new hole was positioned near a security camera, so I was able to watch them do the whole drilling process - efficient and professional, quality of work was excellent. 2.) Trenching to house - Crew showed up approximately a month after drilling - seems like we were put on a monthly schedule once drilling started. Trenching was done in a day and inspection a few days later. Any problem areas in the trench was foamed and the penetration through concrete foundation was clean with no issues. Dirt was put back in place and lawn was actually graded better than I had prior to the trenching. 3.) Heat pump interior work setup - A month after the trenching the crew showed up to finish the work (on the hottest day of the year, mind you). They neatly and efficiently installed the piping and heat pump in the existing furnace location. I thought there would be a lot of piping blocking my crawl space, but the crew went the extra mile and hid the piping up, so the crawlspace stayed open. Electrical installation was clean, with drywall removal minimized. Overall quality of work of the product installation has been excellent. The permitting and initial process took a little bit longer than expected, (the whole process took about a year from contract to install), but I'm glad I will be avoiding the high cost of natural gas this winter in Westchester.

There's no question I would choose Dandelion were I to start again from the beginning. From end to end, they were knowledgeable, helpful, and professional. They streamlined such a massive project into the most efficient, painless process possible. The cost was comparable to other quotes I got for geothermal, and Dandelion offers a much higher level of service and experience, making them an easy choice. Geothermal itself might be a difficult sell compared to other alternatives - in my case the cost was comparable over the lifetime, although I think it would have been more favorable if I didn't require a brand-new duct system as well. But since I went into this project decided on geothermal, Dandelion was able to offer the best value. My only regret with this project is that I used a third-party for my duct installation. I had baseboard oil heating, so I needed a brand-new duct system in addition to the standard geothermal hardware. My sales rep mentioned that Dandelion was starting to offer duct installs as well, but I was hesitant to trust them compared to an experienced HVAC company. But the difference in professionalism between Dandelion & the other company was night and day, and the most stressful part of the install was trying to manage the schedule of two separate companies. I think the install would have been much smoother had I gone all-in with Dandelion. During Dandelion's install, I was very impressed with the high levels of professionalism and care taken by the install crew. They went above and beyond to tailor my system to all of my wants. In the end, everything was exactly as I would have hoped for. We just made it through a fierce heat wave in comfort with our new geothermal system, and we're so glad we made the leap. Dandelion was an excellent partner throughout the entire project. read more

I cannot speak highly enough about my experience with Dandelion Energy. As a homeowner, the idea of transitioning to geothermal energy seemed scary as hell, with visions of massive yard disruptions and complex installations dancing in my head. But Dandelion completely changed my perception with their exceptional service and dedication to the customer experience. From the very beginning, they understood the hesitations and uncertainties I had about making such a significant change. They guided me through every step of the process with transparency and patience, making sure I felt informed and empowered in my decision-making. Their communication was top-notch, keeping me updated on changes in available rebates and tax credits, which ultimately made the transition even more financially feasible. But what truly sets Dandelion apart is their commitment to finding reasonable financing options for homeowners. They recognize that going green shouldn't mean going broke, and they really go to great lengths to make sure their solutions are accessible to everyone. Now that my geothermal heat pump system is up and running, I couldn't be happier. Not only do I feel like a more responsible citizen by reducing my carbon footprint, but I also appreciate the cost savings and efficiency that come with it. Dandelion has turned me into a total convert on green energy sources in the home, and I couldn't be more grateful. Thank you, Dandelion, for making this journey such a positive and transformative experience. You've truly exceeded all my expectations, and I can't recommend your services enough to anyone considering making the switch to geothermal energy. read more

We contracted with Dandelion Energy to replace our natural gas, forced air furnace with a ground-source heat pump furnace in central Massachusetts. Dandelion was very professional and helpful during every step of the process. The project involved drilling two 318-foot-deep holes in our tiny backyard, installing closed loop piping in those holes and connecting the two loops (in parallel) to our basement via a trench in a very narrow path along the side of our house, removing our old furnace, installing the new heat pump system, and using the existing forced air system with the addition of a couple of airflow-balancing ducts. We were impressed with the skills of all the Dandelion personnel from drillers to trenchers to installers to electricians. They were polite, accommodating, and willing to explain the details of what they were doing. The whole process took longer than we wished (Jan 2022 - Apr 2023), which was probably due to personnel shortages as Dandelion expanded into Massachusetts. As expected, we had to add some topsoil and replant grass in our yard, but there is no evidence remaining of the pipes underground. And we no longer have the ugly and noisy outdoor air conditioining fan unit. Overall, we have been very pleased with the results. Even though our house is quite well insulated, our home has been more comfortable, with more even temperatures during this our first winter of heat-pump heating. So far, the system has worked perfectly. We highly recommend Dandelion and its ground-source heat pump systems. Like us, you will feel good for the planet when your natural gas line is disconnected. read more

Dandelion Energy installed a 6-ton system to replace our oil furnace and AC. Every step of the process was managed by our professional and courteous account manager. He handled any issues that arose throughout the process and connected with the individuals necessary to resolve those issues. The whole process took about 13 months from signing the contract, more than they told us up front, however, given that COVID set them back and that they are a growing company, it wasn't horrible. I wish the wait times between drilling, trenching, and install were shorter, but I think that will change as they hire more teams for our area (CT). We had a couple of issues during drilling that were out of the teams control, but they resolved it pretty quickly, during the trenching, we had a bigger issue. Initially, the company did not feel that they were at fault, but after numerous emails and a lot of photos, the company determined that they needed to send another team out to resolve the issue. Our install team was stellar, extremely hard-working, professional, and communicated throughout the entire process. I would absolutely choose Dandelion Energy again if I owned a second home. Despite some of our frustrations, we are extremely happy with our investment, the cooling has been phenomenal. Although I don't want to rush winter, I look forward to experiencing the heating side of things as well. Great company, great system. read more

As my oil water heater was going bad and my AC was way over do, we decided to look into a more self-sustainable solution. With Oil prices skyrocketing we wanted to get away from relying on oil and found geothermal was the answer. Dandelion did a great job answering all our questions about transitioning from an oil-based water heater and furnace to electric and geothermal. The removal of the large AC Condenser from outside of our house removes an eyesore and loud device creating a backyard that is more enjoyable. Not worrying about oil prices is great. Removing of the basement oil tank has provided an exceptional amount of extra storage space. Having the hybrid large water tank that is connected to the geothermal has been a game changer providing much longer hot water. Owning for over a month so far, the only issue we had was with a small water leak from the wall where the pipes came into the house which was patched up quickly and after a few storms we haven't had any additional water leaks. The system has kept the house at a very comfortable 69 degrees. Overall, I would recommend this to everyone who has a house capable of using geothermal. Dandelion was very precise on what the process would be and how long it would take for completion of each step. It was a pleasure working with them! read more

Dandelion finished our geothermal heating and cooling system installation a few weeks ago. Every single person I dealt with at the company was lovely, from the salesman to the installers to the account managers. The drilling process was amazing and fascinating to watch. The inside installation took longer than expected (three full weeks vs. the two weeks they had estimated) but they were very apologetic about the delay and they took the time to get it all right in the end. The system is working incredibly well. Night and day difference in comfort compared to our previous heating system, an old oil furnace. It even kept us warm during the cold blast last weekend, when it was only 6 degrees outside. I am thrilled not to need oil anymore. I can't wait to see how the AC feels in the summer. The project took about ten months to complete, from signing the contract to being completely done. The salesman originally estimated we would have our system finished by "late fall" and that is exactly what happened. It is a multi-stage process and I believe there is a significant waiting list to get started, so if you're interested start the process ASAP! read more

We had units installed several years ago, one stand alone and one with a split, replacing 3 LP furnaces. We expected the cost of installation. We DID NOT expect the absolutely HORRIBLE after-market service. ('can't even call it 'service') and the associated service costs. We've recently waited months for parts supposedly 'shipped to the wrong place'. 'Have bought an expensive service contract which is laughable. All 3 units were just 'serviced' last month and the stand alone has broken down yet again in single digit weather. It's day 2 of waiting for Dandelion to respond with a service date. So, I'm sitting in my home right now with 3 auxiliary heaters running and the room barely keeping 65 degrees, when it's 11 degrees outside. Their unit is running constantly and can't keep up. I can't wait to see next month's electric bill after this. Perhaps they will get here before the end of the week, who knows??? I'd tell any perspective buyers to find another 'green' energy heating & cooling source. This company cannot support the systems they sell. read more

If you're on the fence about geothermal, I'd recommend going for it. If you care about the Earth and/or care about your wallet, this system is for you. If you are patient, as the process takes months from start to finish, this is for you. If you appreciate top notch customer service and a company at the top of its game, call Dandelion. I know the cost seems daunting, I get it, but the cost of financing my geothermal is $80 less a month than last year's propane budget and, while propane will certainly rise in cost over the following years, my loan payment never will. I mean, why would anyone NOT get this system installed? Seriously? Thank you Dandelion. Excellent service, clean and professional install, and it looks and works great! PS- You ever stand near your central air unit, while it labors away midsummer, and feel the heat radiating from it? Well, Dandelion uses that energy to preheat the water entering your hot water tank! Pretty dang cool (pun intended). read more

Highly recommend Dandelion for geothermal install, we did our homework before signing with them and the other geothermal installers were unable to offer the same warranties and 'package' install that Dandelion offers. The other installers basically do 1 of 4 different aspects of the install and they make it clear that 'they won't be responsible for the other aspects.' So if a pipe breaks, you can expect the drillers to blame the trenchers, who will blame the heat pump installers, who will blame the electrical, etc. You don't have that risk with Dandelion, as they handle all aspects of the install. Dandelion walked us through the process from start to finish, the installers were all professional, courteous, and knowledgeable in their respective areas, answered all of our questions, helped us with the clean energy rebates, and we're very happy with our new, quiet, and super-efficient geothermal system! read more

I read the two older negative reviews I could find and wonder whether Dandelion has just improved their service or the reviewers are particularly inexperienced with construction? I'm very pleased with the overall process and with the installation. Everyone I encountered was pleasant and very professional. Yes my front yard was torn up but that was clearly communicated. Yes it took several months for permitting and scheduling but I was never given any other expectation. I'm thrilled that I will never buy heating oil again. P.S. I'm in East Hampton, Long Island and not SF, California. Not sure why Yelp is picking up my location incorrectly. read more

They installed a geothermal heat pump system, which replaced my oil furnace and central air conditioner. The process took a long time, about a year from signing the contract, including four months from the initial drilling to the installation of the heat pump, but it was worth it. I will have to reseed the front lawn and level out the ruts from the machines, but that is a small price to pay to be done with fossil fuels. They removed my old furnace and AC condenser, the install is nice and clean and the system is working very well, keeping my house at a constant 71 degrees. read more

The entire process with Dandelion was an easy, pleasant experience. I got rid of a 2000 gallon oil tank! I have 4 heating zones. My house is now warm in the winter and cool in the summer. The subsidies from the government and Con Ed are amazing. Dandelion files all the paperwork. You don't have to front any money, it all comes off the original estimate. There were a few hiccups in the beginning, but the system has been running smoothly for over one year. I highly recommend this system and company. read more

We are very happy with our geothermal heating and cooling system. In addition to heat, it gives us AC and hot water, which we did not previously have in the building where the new system is installed. We plan to install a solar PV system to offset the power demand from the circulators and fans, but even without that, our electricity bill is very reasonable, and much lower than our propane bills used to be. The financing Dandelion offers makes the whole project very affordable. read more

Dandelion finished installing our Geothermal heating and cooling system in May of this year. Throughout the whole process, Dandelion was with us every step of the way. Everyone whom I had the pleasure of interfacing with has been great to work with. During each phase of the project, you are provided with details on what will occur and the appropriate amount of time the phase is expected to take. If issues arise, you are informed of any changes relatively quickly. read more

I live in Nassau county. My experience with Dandelion Energy has been great. Crews were professional, knowledgeable, courteous, and energetic; they went above and beyond and exceeded my expectation. System used is of high quality and I am already seeing the savings two weeks into using it (I had oil for hot water and heating, plus two CAC units both rated @ SEER 16). The office constantly communicates with me on the progress, especially during the 3rd stage. read more

We had great experience with all the people we dealt with including the energy consultant, drilling, trenching and the HVAC team. People were knowledgeable and explained the work being done with patience. The work site was always cleaned at end of the day and when the system was commissioned. Overall work was completed in less time than expected. The system itself is quiet and working efficiently since it was commissioned at end July. 2023. read more
