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.

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.

Welter is the Man!…read more I have an aging Buderus GB142 condensing boiler that has been having those old age boiler things happening. I had been using a local service with a monthly support agreement but recent experiences with under trained techs led me to search for someone more familiar with my boiler. After having been quoted $4,900 to repair my boiler for error codes and inaccurate pressure readings from Company A, I contacted Welter and he came in and assessed a few problems. The issues were addressed efficiently, parts were replaced, connections were repaired the boiler was deemed ready for service and the total bill amounted to less than 20% of Company A. Long story short, Welter is an experienced plumber, heating pro, with a positive attitude and excellent troubleshooting skills. Highly Recommend Welter for any heating / hot water issues.
