Cobalt Construction

It was a pleasure to work with Dave, as he coordinated all the work extremely well, and everything came in on time and on budget. He was flexible as I considered different options, and didn’t try to push me to the more expensive solution, but rather laid out the pros and cons, and let me make my own decision. I’d highly recommend Cobalt to anyone considering an upgrade, in fact my parents are probably going to use Cobalt to work on their home!

My name is Cliff E. I am the owner of Ecoattics, Inc. Lic #963 041 We are a sub contractor who has worked with cobalt construction on several Energy Upgrade CA projects over the past 3 years. Their clients are in good hands. Dave is the most professional building analyst that I’ve worked with. He and Cobalt construction are committed to customer satisfaction, quality, and professionalism. Dave is always there when I need him. Saying he is knowledgeable is an understatement. I’m thankful we’ve had the opportunity to work together, I have learned a lot from Dave and Cobalt. Thanks for your commitment to Ecoattics, you have truly helped us grow and we wouldn’t have the knowledge we do today if it wasn’t for Cobalt giving us a chance. Thanks Cobalt we appreciate it!

The best thing that ever happened to me was a call from Dave Loperena. I was all ready to go with another company to replace my heating ducts when Dave called me and explained the Energy Upgrade program that he was part of with PG&E. He said I could qualify for a rebate from PG&E. So I decided to give him a shot. He came and did and energy audit and found we had 51% leakage in our duct system. Audit also showed leakage in closet where our heater is installed and in all of my recessed lights. He came up with the same estimate as the other company and told me I would get the maximum ($ 3500) PG&E rebate due to the condition of my ducts. His company did a great job on the duct installation. Very friendly crew did the job in two days. I also got the recess lights insulated at a very reasonable cost. After the final test the leakage was down to less than 6% which was great. Now I have a nicely sealed duct system that heats up fast and keeps the heat longer.
He also mentioned that PG&E had a rebate for a tankless water heater which I was contemplating because of the price. With the $ 1000 rebate it became a no brainer. Now I have unlimited hot water that come on instantly making the whole family happy.
I wrote this review late because I wanted to wait for my PG&E rebate to see if this too good to be true deal was real. Six weeks later I got my $ 4500PG&E rebate. Now I can say Dave is a true to his words. I am a very happy customer.

I talked to several engery upgrade contractors. Dave was had most reasonable quote.
He suggested improvements that resulted in most energy savings and was willing to match quotes from other vendors. I also liked that he kept up with latest changes in the program and suggested Pool pump upgrade that just got added as qualified upgrade.
We were able to complete the upgrade at same time and increase the rebate.
Most other pool/​engery contractors i talked to were not even aware of this program allowing pool pump upgrades.

We own a Residential Care Facility for the Elderly, and decided to take advantage of the Energy Upgrade California PG&E Whole House Rebate Program. We wanted to change our air ducts and replace the attic insulation. Before we met Dave we contacted several different contractors for bids. Some were extremely expensive and others didn’t give us enough information about the process.
When we met Dave, he explained in detail about the whole program and the rebate we’d be getting from PGE based on the upgrades we planned to do. His price was very competitive compared to the other contractors we had dealt with. He was very knowledgeable about the program and we felt comfortable with him so we decided to give him the job.
All the people who worked in our house were very respectful and considerate, knowing that we have elderly people in the house. Dave was involved in the process from start to finish. He made sure that everything was done right. He also submitted all the required documents to PGE on time so we got our rebate right away.
One night after all the work was completed, we were having a problem with our heater. We called Dave and told him what was happening. He came to our house at 8:00 pm to see what was going on and fixed the problem.
Overall, we are very satisfied with Dave’s work. He is easy to talk to, knowledgeable, helpful and very friendly.

We first met Dave Loperena when we were exploring a new furnace. Dave spent time educating us and then testing our house, reviewing any rebates from PGE and finally putting together not only a heating unit but also ducting and new insulation for less than his competitors.
Now a year later we are completely satisfied with not only the whole system but also with their support. I made a stupid mistake last night and Dave as well as all the subcontractors who worked with him, contacted me and worked out the mistake I was making and solved the problem over the phone first thing this morning, Saturday!
Great job a year ago and now. thanks!

Dave is one pretty awesome guy! Offered his assistance and guidance even after we decided to do it ourselves! Genuine! Gotta love that kind of person.

Dave was awesome with the energy upgrade offered by PGE! Explained the program thoroughly and pretty much took full control of the project and he even requested the rebate for me! It took very little effort on my part… he did his job and went above and beyond! Great job to Dave and to the team that helped with the work!

Talked to PG & E rep at a homeshow about their energy upgrade program/​rebate. Dave from Cobalt came out and gave us a quote on installing a new heater, ductwork and attic insulation. He was understanding of us not wanting/​needing the highest efficiency heater and worked with us on a payment plan.
His subcontractors, including EcoAttics and Integrated Air, worked well together, and they did an energy audit (part of the PG & E program) as well. Work was done quickly and efficiently, and the guys were all friendly and eager to explain what they were doing (more than I really needed to know, but it’s nice when professionals are proud of their work and can explain it in simple terms).
We qualified for the maximum PG & E rebate, despite not getting the highest end heater or the most costly work done, as we initially suspected we would have to do. Overall, after rebate we paid just over 4K and our first heating bill after the new heater/​ducting/​insulation went from $ 430 to $ 130. Even with the slight decrease in the outside temperature we know we made a great investment. And we actually have heat that we can feel now in our master bedroom!
