Zero Energy Associates reviews

The Verdict
Zero Energy Associates runs a tight ship on install days, but getting a callback after the crew leaves can take months. We analyzed dozens of reviews and found 14 customers praising the workmanship itself, from ductwork adjustments to heat-pump installations that dropped electric bills below $100 a month. One homeowner froze for days waiting on a furnace repair, then watched the crew troubleshoot low airflow in real time, crawl back under the house, adjust dampers, and equalize the registers in 15 minutes. That same professionalism vanishes when you need a tweak. One customer spent two and a half years on a callback list for uneven bedroom heating, finally gave up, and hired someone else. Another waited months for a simple solar follow-up. Daniel Smith's crew earns universal marks for clean installs and passing HERS inspections, but the company has downsized to two teams and the queue shows it. If you can live with a furnace that heats unevenly for a year or two, the install quality is solid. If you expect the installer to fix minor issues without a multi-season wait, look elsewhere.
If you need an HVAC or solar system installed correctly the first time and don't plan to call for adjustments, Zero Energy will deliver. If you value responsive post-install support as much as clean work, the two-and-a-half-year callback wait makes this a risky hire.
Reviews That Shaped Our Verdict
Miles has relied on Zero Energy Associates for more than 10 years to install and maintain a range of HVAC systems for his rentals and his own ranch-style home. He found every installation still performing reliably, and the systems that required HERS ratings consistently earned the top marks — the HERS inspector even praised Zero Energy Associates as one of the area's highest-quality companies. None of his rental units have experienced issues, and the system on his personal house has been trouble-free. He gave Daniel and the team five stars for their customer service and workmanship. What stands out is the decade-long, trouble-free performance combined with independently confirmed HERS excellence.
Gay J. had Zero Energy install a very green, eco-friendly furnace and extensive ductwork in her home three years ago, and the initial job looked solid. Three months later she discovered two upstairs bedrooms weren’t getting enough heat and began calling for help. Technicians suggested increasing the fan speed or fiddling with settings to shove more warm air upstairs, but the problem never got resolved. She kept calling and waiting for 2.5 years with no lasting fix or return visit. When she phoned again today, a technician named Daniel told her she was pulling “attitude” for complaining about the follow-up; she pushed back, reminding him she’d been on his list for 2.5 years. Daniel explained the company had downsized and now runs only two crews. Frustrated by the long delay and that confrontational exchange, she will hire someone else to adjust the furnace.
Bob Samuel had been freezing until the company took on a mixed HVAC and solar project at his home. After the crew finished the work, cleaned up, turned the fan and heat on and adjusted the controller, he walked the house and noticed weak air coming from the four living-room registers while the two dining-room registers were blowing strongly. The technicians explained the dining runs were on direct lines, went back into the system, tweaked a series of dampers, and in about 15 minutes produced much more equal airflow across the living area and the rest of the house. He ended up with balanced heat everywhere. The most striking addition wasn't the ductwork but a compact 3'x3' attic heat pump that handles all of the household’s hot-water needs: it pulls heat from the cold attic and feeds a water tank instead of a conventional water heater — a setup he found nothing short of a miracle. A few years earlier the same company had installed a large solar array for him; the panels have been performing well (he can pull up the system results online), even though dealing with the utility has been complicated, and a good rain will help wash the panels.

What You Can Expect
Douglas L. runs a neighborhood coffee shop and hired Zero Energy to put in a split-system AC/heater. He compared three local HVAC quotes and Zero Energy not only beat them on price but also finished the install quickly and left the shop clean. The unit has run without problems for three years, and the combination of lower cost and trouble-free operation is what stood out most to him.

Stephen Rosenthal had ZERO Energy come back to expand the rooftop system they installed on his home last year, asking them to add four solar batteries. He watched the crew arrive on schedule, tie the new batteries into the existing array, and finish the work without any disruptions. He found the price fair and the communication and on-site service consistently excellent throughout the process. What stood out for him was how effortless the whole expansion felt—seamless integration, clear updates, and a tidy install—so he plans to call them again if he needs more work.
