"From start to completion everything for the initial quote, to showing up on time, to completing the job quickly and cleaning up was absolute professionalism. Kent , the owner, was great and everything he told me was correct. I have waited to post my evalution because I wanted to receive my first utility bill after completion. My utility bills in the summer were ranging from $250-$300 a month. I have a 2267 square foot home with a pool. My first bill since my new installation was $200.00, a wonderful drop from last year. The pool uses a lot of energy. Before, my garage was incredibly hot in the summer and I can really tell the difference. I leave my thermostat on 78 and it is actually cold at night. I highly recommend them.

"Overall the experience was a pleasant one. The work was completed very promptly when they got the part, which only took one day as my service call was late in the day. The initial visit was scheduled for a 3 hour window, however they were an hour and a half late with no call to let me know. I would have preferred a call to let me know, but it wasn't a big deal. They wear little shoe covers any time they enter the house, which I really appreciate. I also had an issue with 1 room being warmer and the technician checked it out and corrected the minor problem causing it for no charge. (Something in the attic was just tossed on to the duct that went to that room, almost completely pinching it closed.)"

"The guy who used to come out and do the maintenance of our unit, used to work for another company. He’s a really great guy. So when he started his own company we switched over to his company. He’s excellent and he’s a really good guy. The people that work there are excellent. They are very honest. They are very nice people and very polite. They are very thorough. They are very professional. If they find something wrong, they take the part and make sure if it’s under warranty and then get the stuff if needed. They are very conscientious. Their price is excellent. They are very responsive. When I call them and if they don’t answer, they call me back. The quality of their work is excellent. I would use their services again in the future."

"We met with 3 different companies to advise on getting solar panels. The first 2 companies basically just told us what size system we could get based on state and federal tax rebate levels. Heard an advertisement for Sunpro on radio and decided to call them; turned out to be a good decision. Kara with Sunpro was extremely informative and had a nice package put together for us to review. She even researched our home and had an idea of how much production we could expect with the recommended solar panels. Even after selecting Sunpro, I called Kara with questions about things I'd heard from others or something I forgot to ask. I never felt like I was a burden and she always returned my calls if I had to leave a message. The complete team with Sunoro were professional and eager to help. Satisfied with new solar system and looking forward to enjoying savings on electric bills.

"I recently reached out to collective power to inquire about their energy solutions and services. Although I didn't have any services done with them, I was thoroughly impressed by the level of information and assistance they provided. The representative I spoke to was knowledgeable and patient in answering all of my questions. They took the time to explain various energy options, their benefits, and the potential cost savings. I appreciated their willingness to provide detailed insights, even though I was only seeking information at that point. Based on my experience with their customer service, I can confidently say that Collective Power values their potential customers and strives to offer valuable guidance. While I cannot comment on their actual services, the positive interaction I had speaks volumes about their commitment to customer satisfaction and transparency. In conclusion, if their service matches the quality of the information they provide, I would not hesitate to consider Collective Power for my future energy needs."

Energy Efficiency Auditing FAQs, answered by experts

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.
