Our water heater was over 10 years old and it started cycling heat on most of the time. Based on…read morepositive reviews, we called Joe, of Wolff Heating Cooling and Plumbing to replace it. First, he said he needed to make sure we didn't have a leak. Well...we had a slab leak. He referred us to a fantastic plumber (Eddy Ks Plumbing and Heating) that fixes leaks under slabs and he did a phenomenal job. We still wanted to replace the water heater so Joe was patient while all the excavation, repair, and restoration work was done. Joe did a great job replacing our water heater and even built a new stand/table for it. We were billed what we were quoted and he showed up on time and was very professional. We will definitely call him for any future heating, cooling or plumbing needs.

Brandon came out to do the estimate and was always quick to respond to my questions. I obtained five estimates, and NCB's price was by far the most competitive. Once I accepted the quote, the installation was scheduled within just a few days. Brian completed the installation and was professional, courteous, and easy to work with. There were a couple of minor issues after the installation, likely due to a miscommunication, but I contacted Brandon that evening and everything was corrected by the next morning. I really appreciated how quickly and professionally they stood behind their work. Overall, everyone I dealt with at NCB was friendly, responsive, and professional. Based on my experience, I would definitely use NCB again and wouldn't hesitate to recommend them to others.

DO NOT HIRE THIS UNETHICAL AND CRIMINAL COMPANY In Albuquerque, NM, HVAC companies must obtain…read moreseparate electrical and mechanical permits before starting work, as required by the New Mexico Administrative Code (NMAC) 14.5.2.8 and City of Albuquerque ordinances. Mr. Robert Pallulat of Nespolo Mechanical failed to acquire these work permits as required by National and New Mexico State Laws. These regulations ensure that licensed contractors perform work--such as installing, replacing, or altering furnaces, air conditioners, or ductwork--to meet state and local safety codes. * Permit Requirement: Separate mechanical and electrical permits are required for heating or cooling and electrical wiring, respectively. Nespolo Mechanical failed to acquire either of these permits. * Mandatory Licensing: Only licensed contractors are authorized to pull permits for, install, and obtain inspections for HVAC ductwork and equipment. * Law Source: These requirements are mandated by N.M. Admin. Code § 14.5.2.8 and local Albuquerque building guidelines to ensure safety. Mr. Robert Pallulat of Nespolo Mechanical violated this Administrative Code by failing to pull both electrical and mechanical permits. * We never demanded anything, we asked to speak with Mr. Pallulat due to his journey men refusing to answer our questions and redirecting us to speak with Mr. Robert Pallulat. We called and texted Mr. Pallulat (please refer to evidence folder) and he responded with informing us with the following text: "I am at a training, I will call you back during lunch." We agreed to halt work until we had a chance to speak to Mr. Robert Pallulat, but it was Nespolo Mechanical that decided to stop the work altogether. It turns out that Mr. Robert Pallulat was not in fact at a "training," and he was instead getting extensive dental work done and not able to speak. I have provided Mr. Robert Pallulat's text response that he sent on the late evening of March 12, 2026 explaining that he could not speak due to anesthesia. Before we even heard that much from Mr. Pallulat, however, the Nespolo Mechanical crew member Ricardo Rivas returned hours after the work order had been stopped to ask if he could retrieve "something he forgot" from the back, and he then roughly ripped out the furnace they had begun installing and dragged it through our backyard and out of our property. Nespolo Mechanical has advertised on public television that they are clearing out their warehouses and offering "free furnaces" but the ground truth is exactly the opposite. They have distorted a rebate offered to any HVAC company by the manufacturer into a deceptive fictitiously false advertising campaign. Nespolo Mechanical, specifically Mr. Robert Pallulat, are attempting to distort the chronological sequence of events in order to distract attention away from the fact that they were in violation of the State of New Mexico building safety codes when they bypassed the permit process from the outset: * Process: Contractors must file for permits before starting work, and work must be inspected by a city inspector after completion as required by as required by New Mexico Administrative Code (NMAC) 14.5.2.8 Consequences of Not Pulling Permits Failure to pull permits in Albuquerque can lead to fines, work stoppages, and required removal of equipment to pass inspections. It is the responsibility of the licensed contractor (or homeowner in limited cases) to pull permits before work begins. The Nespolo Mechanical HVAC project was stopped BY Mr. Pallulat of Nespolo Mechanical. They had ordered and brought to our job site a 24-inch coil, and Mr. Pallulat had informed his crew to make room for that 24-inch coil. It was when the workers on site drew our attention to 24-inches being the incorrect size for the furnace they had already begun to install that we began asking questions about what was supposed to be present and only then were subsequen serious concerns raised. Our family - our one year old child - was left without a working furnace in freezing temperatures. Mr. Pallulat told his crew to abandon our work site and clear all equipment and materials, leaving our old but fully functional units out in the yard exposed to the elements, and therefore rendering them unsafe for further use. Mr. Pallulat failed to contact us until the following day via an extremely insulting and flagrantly inflammatory email which we will respond to here in detail, item for item (please see the email and our included responses below). In addition, we have audio and video recordings that clearly document the Nespolo electrical worker describing how he planned to install the electrical lines. The drill holes he left on our wall and the hole he drilled through it illustrate the path of the electrical lines he planned to install before we agreed to halt the project until we had received confirmation and clarification from Mr. Robert Pallulat, when he was supposed to call us back "during lunch"

I felt like they were inappropriate, so I called #1 to review the "other" companies work. They were able to point out the flaws that would block my new heat pump from being green-tagged. They pointed out the green tag was missing. They didn't charge me. So, I called them again a few months later because they proved themselves to be honest people. They came in, took care of my seasonal tuning and a toilet that was not flushing. I think I've found my trusted plumbers, and that's a hard thing to do! 10/10 recommend!

I called Zach Smith out to check my AC unit his tech came out and miss diagnosed the problem they finally fixed the problem but it took a month and it should have taken a week max then it stops working again 2 weeks later and I called him out almost a month ago he said it was a different part and he would get it ordered and I still have not heard from him to this day. I called Dario from Diamond Mechanical ànd he was so respectful, kind and professional called me every day to update me on shipping of the parts.
