I wish there were an option to give 0 stars…read more This company has been a nightmare to work with. I had solar panels and a heat pump HVAC system installed by them. At the beginning, I was impressed by their professionalism and promises. However, although they kept saying "yes" and assuring me things would be handled, nothing was actually done. Weeks turned into months with no real progress. My project started in October 2024. The system itself works well, but the sheet metal inspection is still not completed. This has been dragging on far too long, and the lack of follow-through has been extremely frustrating. I strongly recommend avoiding this company. Based on my experience, working with them has been extremely frustrating and disappointing.

My project ended up not being the easiest however, I could tell throughout he never took his focus away and did everything possible to help support me whether it was with the utility, understanding options, permits, paperwork etc. I never felt out of my depth and knew I had his guidance at each milestone.

Where other contractors canceled appointments, arrived late, or were just no-shows - Mikel (out of their Hudson office) arrived on time and did a thorough assessment of the roof including taking drone footage. He sat with me and walked me through the whole process clearly, explaining all my choices in materials and didn't push any product or add-on. I did receive marginally cheaper quotes, but they did not leave me feeling like my home was in good hands in the same way that Mikel did, and I felt the extra money was likely to be worth it. Once I decided to go ahead with them, again, everything was done very professionally. I was kept informed of times and everybody showed up exactly when they said they would. I made a small change to the scope of the work in replacing additional plywood sections of the roof, and these were easily accommodated on short notice. On the day of the work, the crew showed up on time and Jurgan (the site foreman) kept everything moving with minimal disruption to us. I was working from home, and my wife and kids were in and out of the house for school and errands. Despite replacing the entire roof of the main building and two additions over approximately 9 hours, there was minimal disruption to our days. The house was protected during the work, and even with snow still on the ground, their cleanup crew constantly walked the property picking up and disposing of any debris, nails, old material etc. Ultimately the roof was replaced successfully and looks good. Every step of the job was explained to me, every question answered, and every decision explained. The team was professional, punctual and courteous throughout. A couple of weeks in and we've had snow, rain and strong winds. Everything is still perfect. I can highly recommend Mikel and Jurgan from Golden Group, Hudson.

UPDATE: A few hours after writing this we LOST ALL HEAT DURING A BLIZZARD. No power interruptions,…read moreit is THE SYSTEM NOT WORKING YET AGAIN. Called only to be told we'd get NO help or support for two days. Our entire house is only around 55 degrees now and we can't safely leave. DO NOT USE THIS COMPANY. I am so unbelievably upset. We called Friday asking for help and now here we are, heatless with two kids home during a blizzard. ----------------------------------- I waited a long time to write this review because we gave SumZero many opportunities to correct ongoing issues that have existed since day one of installation (a few years back). Unfortunately, we continue to have persistent problems with both heating and cooling. We have two young kids and at this point it is unacceptable these issues haven't been resolved. In the summer, our back room with vaulted ceilings is consistently 5+ degrees warmer than the rest of the house. In the winter, that same room is always about 5 degrees colder. The main living areas also had issues for the first few years, struggling to maintain temperature in the summer and leaving the house humid and unable to hold the thermostat setting some days. After extensive back-and-forth, SumZero ultimately replaced the entire outdoor unit, stating we must have received a "lemon." That replacement was installed this past summer, yet the temperature imbalance in our back living room remains unchanged this winter. Separately, we were provided a mini-split for our partial basement living room. That unit is unreliable and often does not work at night. The settings are correct, we have tried power cycling and resetting the breaker, and it still works only intermittently. It has been set to 68°F for days, yet the room is currently 56°F with no warm air blowing, despite the unit being on. My husband and I have contacted SumZero countless times over multiple seasons and years. Even after replacing major equipment, we still do not have a system that can adequately heat and cool our home as promised. The heat pump system installed through MassSave has never performed adequately in the years since installation. I understand that some older heat pumps can struggle in extreme conditions, but high-efficiency systems (like one we should have received via MassSave rebate with SumZero) should be able to handle New England winters and hot, humid summers., from my research. Ours cannot do either consistently. At this point, we are exhausted from having to address these issues every few months. While the customer service representatives and technicians are polite, no one has been able to properly fix the system. I strongly recommend going with another company if you want to avoid a long-term headache. Photos show mini split remote temp set to 68 but room thermostat shows 56, this is a common occurrence. Other photo shows main house ecobee (new thermostat for heat pump unit) set to 70 (has been set to this for months) but it's only at 65 in reality and continues to go down. The back room with vaulted ceilings thermostat currently reads 59 even though it should be at 70.

Great company! Honest people and fair prices…read more If you're anything like me, you hate shoddy work, and in the home remodeling industry, there's a lot of that. I would rather pay a premium to ensure it is done right and the quality is there. SumZero does that and more. We called, and within a day, they sent one of their experts, Raphael G., to quote us for ductless mini-splits to outfit our home. He was very thorough, offering different options that would work for our living room and bedrooms, which are boiling and humid during the summertime. He made the process extremely easy for us to understand and was willing to work directly with our condo association to accommodate their requests. We're still waiting to get them approved by our condo association, as there is a lot of work involved in obtaining approval. However, so far, the experience has been nothing but easy and painless. I'm looking forward to having the mini-splits installed.
