Q: Do energy-efficient windows really make a difference?

• <div><p>Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.</p></div>

Q: How do I check the humidity in my house?

• <div><p>You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.</p></div>

Q: Do under cabinet lights use a lot of electricity?

• <div><p>If you install LED bulbs, they will use much less energy than incandescent bulbs. LED light strips also use less power. Battery-operated puck lights use no electricity at all, but you will need to replace the batteries as needed. They are beneficial if your power goes out, too, as they will remain on as a light source. </p></div>

Q: How long does an energy audit take?

• <div><p>Audits typically take 2-4 hours, depending on the property size and energy systems.</p></div>

Q: Will a new boiler mean lower fuel bills?

• <div><p>If you want a new boiler that&rsquo;s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated &ldquo;A&rdquo; uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it&rsquo;s important to have it installed properly by a highly-rated tech.</p></div>

"No doubt they hire great installation people, but their communication and honoring their quotes has little to be desired. I will elaborate. I was given a quote, left on my voicemail. I responded the next day letting NRG know I accepted their quote. 1 week later I received a phone call telling me they wouldn't honor the quote give, and they cited the reasons as Tarif's. This was back in April 2025. I still went with NRG, albeit at a$1000.00 increase. The second reason I wouldn't recommend this company, and this for me is the final straw, after installing my solar NRG didn't let me know I needed to have an ESR release, in layman's terms this is necessary for your power company to accept your new solar system. I found out this information when they contacted me in August 2025. NEG blamed the company who upgraded my Electrical Panel. NRG INSTALLED MY SOLAR AFTER THE PANEL WAS UPGRADED. Since this company doesn't communicate with its clients I would say go with another company."

"Trust has been broken by nearly everyone I have talked to at Smart Energy Today/Lumio. It has been over EIGHT months now since my first signing with your sales representative, Josh Miller. Summer has come and gone, and we STILL have no working solar panels with zero communication from anyone in your organization on when this will be completed. The absolute TERRIBLE experience we've had was as follows: 4/14: Spoke with Josh Miller. We were told if we signed that night, we would be given 3 months worth of payments. Signed that night. 4/15: Welcome email received from Smart Energy Today with timeline saying target 6-8 weeks from finance approval with picture showing maximum timeline of 12 weeks, which would have been 7/15. 5/10: Got an email requesting for documentation with my name on the property. House is under my husband's name, so we needed to add his name to the loan. 5/24: Signed new documents with my husband's name on it. New maximum timeline should have been 8/24. 6/22: Solar panel was installed roughly around this time. After the install, I got a physical copy of a timeline showing a timeline maximum of 84 days plus one step that had a variable date range. New maximum timeline should have been roughly 9/22 without knowing what the variable timeline is. This was the final update to the timeline I got, so as far as we are concerned, this should have been the target date. 6/23: Inspection was supposed to happen in the morning. Waited until 1 in the afternoon with no one showing up and no word on when the inspector would be coming, we needed to reschedule due to work. I was told someone would call me back to reschedule, but no one ever did. I had to reach back out to Josh for help to get the inspection rescheduled. 7/2: Got letter from Service Finance Company that our first payment is due 7/28. We asked Josh about this since only the solar panels were installed, but our main panel which needed to be replaced due to age was not installed yet and was rolled into the loan. Josh acknowledged that this seemed odd and would look into it. 7/21: We got our first bill from Service Finance Company. Sent to Josh again, he said he'd look into it.8/16: Main panel replacement occurred. On the same day, we got a call from Service Finance Company that we are 19 days overdue and will be going into collections soon. Reached out to Josh again about this, and Josh promised he'd pay for the late fee. 8/18: Finally got a gift card from Lumio with the first three months of payments that Josh promised us. Since we had to resign the loan for a new amount since the main panel was rolled into the loan, the gift card was for 3 months based on the old amount, not the new amount, and it did not include the late fee that Josh promised. Was told I would get an additional gift card for the remainder by a representative who called me to confirm I got the gift card. 8/19: Got a survey from Lumio about the solar panel install. I took the survey and fully explained the horrible experience I had up until that point. The survey asked if I would like someone to contact me, and I said yes. To this day, no one has contacted me. 9/2: City of Seattle came to inspect expecting a Lumio representative to be present, but there was no Lumio representative. Josh said that no Lumio representative should be onsite. Via email, Jennifer said a Lumio representative should have been onsite. I told Jennifer Josh said this wasn't necessary, and Jennifer said there should have been. Rescheduled inspection. 9/13: Got a text from Jennifer saying I needed to schedule an inspection again, which made me think the previous inspection scheduled on 9/2 did not occur (error on her part). 9/17: Texted Josh asking for a follow up on the gift card. Zero acknowledgement. 10/12: Texted Josh again about the gift card. Josh texted me an email screenshot Alexa Gamble sent to Rachel, AJ, Catherine, and 7 other people for follow up. 10/20: Text from Ivie to schedule final electrical inspection for 10/27. I texted back requesting for 10/28, but didn't hear anything back from her. 10/28: No one shows up. 10/31: Text from Ivie saying that the technician had an emergency and her text to me never went through, now the final electrical inspection is scheduled for 11/10.11/4: Texted Josh about the gift card. Zero response. 11/10: Lumio inspection with Seattle City Light. Was told additional work needed to be done. It has been two weeks, and I have heard nothing back from anyone about when that would be scheduled or take place. This only includes the correspondence I've had in writing with your organization. This does not include the countless phone calls I have made to follow up with your inability to provide clear communication and follow through. In writing this and reliving the experience I had with your company, I am completely astounded by your organization's inability to follow up your customers. It's not just one or two, but multiple people who have dropped the ball with communication with us."
