I have pets and toddlers and they took my concerns about chemical disinfects seriously and offered several options to make sure I was comfortable with what was used in our home. They really seem to take pride in their work and enjoyed sharing before and after pictures to demonstrate all the improvements they made to our crawl space.

My house used to have cold spots and heater would kick on every 20 minutes. Now there are no cold spots and the house stays warmer a lot longer and again much quieter from external noise. I would highly recommend his services.

I went out for four bids, and Element was the last one. The equipment and pricing were all over the place, and honestly, I was getting pretty frustrated by the time Ernest from Element showed up. From the start, he stood out. While others barely glanced at the attic, Ernest went straight up there and spent more time than anyone else had. When he came down, he pointed out two big things: first, my system needed increased airflow, and second, getting the old unit out was going to be a tight squeeze. I could tell he actually cared about the details. He recommended the smallest unit that had been bid so far, which surprised me. I brought up efficiency concerns because another model seemed better on paper. But Ernest explained that for our specific climate, heating performance mattered more--and the smaller unit he recommended was actually more efficient in that context. When I got Element's quote, it wasn't the cheapest--but it was the most complete. It included everything: permits, inspections, even replacing three ducts. There were no surprises. I had a few more questions before moving forward, and Ernest took his time answering every single one. Once I signed the agreement, their project management team was punctual and professional all the way through to the certification process. The whole install was done in a day, just like they promised. I'm more than happy--not just with the heat pump itself, but with the entire experience. Everyone I interacted with at Element was professional and easy to work with. Highly recommend.

We moved into a new home last November that was substantially bigger than our previous rental…read moreapartment. We were much colder than we had anticipated, given both the increase in space and the antiquated (35 years old!) furnaces that it came came with. Worse, still, was the weighty PG&E bill that came through just a few weeks later. Ouch. As things started to warm up, we started exploring options to replace our 36 year old furnaces which we knew were a ticking time-bomb in the fear of having to house my Southern Californian in-laws who would not tolerate anything but a balmy 72. We spoke to 13 different vendors, based on Yelp searches and those little coupon books that we seem to get monthly in our mailbox. Element was one of those coupon book vendors but when I went to look them up on Yelp, I was pleasantly surprised. Ernest came out in spring and spent over an hour with us, measuring the size of our registers, inspecting all of our ductwork, and answering all of the questions I had about what kind of improvement we could expect. Then, we waited. There are a lot of decision points to make: should we replace our ducting, what kind of ducting should we get, heat pump or furnace, what efficiency furnace, AC or not? Half a dozen other projects happened over the summer and as the days drew shorter, I decided to go ahead and resurrect our furnace discussion. The benefit of waiting over the summer was that we discovered AC wasn't really necessary where our house is, due to the tree cover that keeps the house cooler. However, the air quality in the Lamorinda area was about as bad as anticipated (200+ AQI), with the now unfortunate annual wildfires. This, plus some consulting with both Ernest and our pest control contractor, helped us decide on: new aluminum ducting (rat proof!), a high efficiency furnace, no AC for now (but a coil so that we could easily install it later), plus some pretty heavyweight IQAir filtration. Unfortunately due to all of the supply chain issues, the price for our estimate went up by $2K or so since we originally reached out. That said, not installing central AC saved us $7K or so - so waiting was likely the right decision. Element's quote came in very competitively against other vendors, who were cheaper on the furnaces but more expensive on the ductwork. What I liked about Element (and Ernest's salesmanship) was the numerical and very professional way they approached the system design for our home and how duct sizing was based on solid engineering principles. I was a little wary about the duct work (it is not cheap) This professionalism carried through to the crew who came and did the install, and their office manager Mac. We had a few issues during and after the install - because this is the real world after all - and Mac and the team made sure to follow up on each of these. Our water heater went out and so we had no hot water for a couple of days. We weren't able to relight it ourselves and it turns out it needed a new ignition unit - the team at Element sent a technician over and a plumber when that failed. There were a few small cosmetic blemishes left over (marks on the wall, and some construction mess in our subarea) that they fixed immediately when prompted. We also were missing an overflow valve on the AC unit that caused inspection to fail, but they came out and installed that before scheduling another inspection which passed. So far, in two weeks of having this new heating system, we are very very happy. The house heats up from 62 in the morning to 70/71 much quicker than before. The system is about 1/5th of the noise of the previous system - with the new fatter ducts, there is almost no discernible "whoosh". The house heats evenly too - areas of the house that would get too warm before are now about right, and our living room with a high ceiling actually gets comfortably warm. The furnaces seem considerably more energy efficient too - using about 2/3rds the natural gas despite the fact that we typically run them for twice as long! Our electricity usage is a few kWh lower each day too. Overall, pretty happy with Element and their work. I wish this sort of project didn't cost nearly as much but hopefully we can stretch these furnaces another 35 years ;-).

I usually like to give…read morecompanies the benefit of the doubt and give them opportunities to make it right, but my experience with Attic Masters and Adam have been nothing but endless frustration. First, they didn't show up to our scheduled appointment on Nov 29, at 8AM even after I received 2 confirmation emails, and text reminders about the appointment (attached below are photos of the confirmations). I specifically chose this company over Attic Bros because I was told that they work on the weekends and complete jobs on weekends. In hindsight, I wish I would have just gone with Attic Bros from the start. Two guys came at 2:30pm instead on Saturday after I had called them at 10:30am about how no one showed up. The 2 guys only put up 2 films of radiant barrier and left at 5pm. On Sunday morning, the remaining workers showed up and "finished" at 2:30pm, however they didn't rodent proof my crawl space until I had pointed out the holes to them. They did it after I had pointed out the holes. Additionally, they never rodent proofed my the attic side vents. They rodent proofed the roof, sure, but I would have thought the side vents would be included (they didn't have a ladder to reach it so they didn't do it). I had to hire a third party to fix the holes/gaps on the side vents instead because Adam and his company didn't want to come back to fix it. I was told they'd call me back when they can schedule me in, but after a week I gave up and just hired another company. Also, they damaged one of my kitchen lights when they were doing work in the attic. Adam also said he would send someone to fix it and that it's "easy" but nothing ever came of it. The 3 stars I gave them is because the insulation looks decent and that they still came on Sunday to follow through on the project, but if they could lie to me about "fixing the side vents from the inside" who knows what else they may have lied about. I am concerned about this company's integrity. Also- Adam is rude and defensive on the phone, and doesn't really let his customers speak.
