"Excellent company! We had a residential solar system installed in 2014. We started having problems this year with reduced production, and any rain would knock the system offline for several days, up to a week or two. The company we used was one of the many fly-by-night companies that flooded the valley during the solar boom. Like most, the company went bust. We had a great warranty, but the warranty doesn’t do much good if the company is long gone. Many of our neighbors had solar systems installed after ours and they all used Today’s Energy Store. They are all very satisfied with their systems and recommended we contact Today’s Energy Store for potential repair. Today’s Energy Store also has a second company, Solar RX, that is dedicated to system repairs. Mark, the owner, came out to evaluate the problem and came out two more times to discuss repair options. The wiring on our roof was a mess and many of the connectors had failed. One option Mark offered was to repair the wiring problems they could find, but we would most likely have continued problems in the future. A second option was to replace all the wiring and convert our DC system to AC, which is more efficient, by installing micro converters on the panels and removing the large inverter in our garage. That is the option we selected and had four additional panels installed at the same time since the original installer undersized our system. The price for the conversion and additional panels was fair and the panels that Today Energy Store sells, Sun Powe, are a much higher quality than the cheaper Trina panels that our original installer used. After Solar RX completed the repairs, they found that some of our panels were not producing, and others were producing very little electricity. Mark did some research and found that Trina had problems with panels they sold during the period when our system was installed. Solar RX sent a technician out on three separate occasions to take pictures, get serial numbers and document output readings. Solar RX contacted Trina, confirmed our panels were still within the manufactured warranty period, filed a warranty claim on our behalf, provided all the documentation and pictures and persuaded Trina to replace all 36 of our original panels. The effort Solar RX expended to have Trina replace our panels under warranty was amazing. Trina replaced the panels but would not cover that install costs. Solar RX installed the 36 new panels for a very reasonable cost. When all was said and done, we ended up with an entirely new, much more efficient system, with additional capacity, for a very fair price. We couldn’t be happier with the service provide by Solar RX. Kudos to Mark, the owner, who came out to explain the problems and solutions and helped with the work; Justin the technician that we worked with on multiple occasions who is the consuamte professional, friendly, very knowledgeable of solar systems and a very hard worker; and Lynne the Project Manager who worked with us diligently by phone and email, answered all of our questions and quickly responded to concerns. We highly recommend Today’s Energy Store / Solar RX to anyone that is considering installing a solar system or has a system that needs repairs."

"From setting up an estimate to the date of service, it all went smoothly. The only hiccup which was corrected was the miss that our garage ceiling slanted rather than being flat. From speaking with Charlene in setting up the appointment to Danny coming out to do an estimate and Roberto who did the work, they were all personable and professional. We have worked with them previously and Will came out back on 2015 and the job went efficiently and painless. The money spent was worth the investment and fair."

"If I could give 0 stars I would. I purchased a completely new hvac system for my elderly mother who is also sickly and now trapped in a home that is over 90 degrees because we cannot afford to fix this issue on our brand new system. It was installed December 31, 2021. The company came out in 2022 3 times to fix failures. In 2023 they've come out twice. Now, 18 months later on a $10k unit, the compresser failed and needs replacing. This until should get 15 years without issue and didn't even get 2. Ambient edge REFUSED to replace it without us shelling out $2300 on labor (only) as the unit itself is under warranty. They claim that they are not liable to fix any issues from Mojave air whom they assumed last year and actually suggested I reach out to the deceased former owners family to see if they will cover it!!!!! To put a nail in the coffin, the customer service manager REFUSED to provide me with a copy of my receipt where she claims it says I only have a 1 year labor warranty. Sounds pretty fishy right.... She also claimed they are not responsible for the work of the company they assumed which sounds rife with illegalities. I spoke to the State Contractors board who urged me to start an investigation as there is 4 years of implied warranty for this type of work. I will be going forward with that as well. Do NOT use this scamming company. Read the other reviews. They are scammers who DO NOT CARE about their customers and will rip you off to save their bottom line."

Home Networks started out a computer services and network cabling business in the South Bay Area with a C-7 Low Voltage classification. Because of the frequent request for electrical services, we incorporated a C-10 Electrical classification in 1999. We integrated Smart Homes with our knowledge of technology and Electrical. As the economy tanked in late 2008, our customers were interested in energy efficient fixtures and alternative energy solutions. We then evolved to who we are today Home Networks, Electric & Solar adding our C-46 Solar classification. Tesla Powerwall 3 Authorized Dealer and installer. SPAN.io Authorized Dealer and installer.
"Terrible Experience -- Unreliable and Unprofessional My experience with HNES has been nothing short of terrible. I hired them to install a Tesla Wall Connector at my home, but after 40 days, the project was still incomplete. To make matters worse, they lost a crucial part, the DCC12, which brought the entire installation to a halt. Adding insult to injury, they refused to refund the $1,000 deposit I paid—$500 initially and another $500 for the DCC12 part they mishandled. Their lack of professionalism, accountability, and respect for their customers’ time and money is outrageous. This has been one of the worst contracting experiences I’ve ever had. Save yourself the frustration and look elsewhere for your EV charger installation."

Family owned and operated! We provide expert service on all makes and models of air conditioning and heating equipment in Las Vegas. We specialize in air conditioning and heating repairs, replacements, and maintenance tune ups .
"My central air stopped working on Sunday night (during one of our famous Las Vegas heat waves). I called late on Sunday night, and Jacob from Air Zone was at my house by Monday early afternoon. He inspected the unit and quickly found a problem - one of the fuses for the air conditioner had blown. He said he needed to find-out why the fuse failed, and he found that the capacitor was bad (which caused the fuse to fail). He had all the necessary parts on his truck, and we were fixed up within about 15 minutes! One thing I really like about Air Zone (I've worked with them before) is that I trust they will only fix what is broken and not try to up-sell you on expensive repairs you might not need. Jacob talked me through why the parts failed, what I should look for in the future to spot a similar failure, and gave me some tips on maintaining the outside part of the air conditioner. We have two units at our house, and the other unit kicked-on while we were talking about the one he just fixed. He said, since he was there, that he might as well check the other unit. He did a quick inspection and said we were good to go (again, not trying to push any services I didn't need). When he was finished, he cleaned-up all of his tools and left us very happy with our repair. It's great to have found an honest and skillful air conditioner repair company. Thanks to their quick service, we didn't have to move family/pets to other parts of the house (or a hotel)."

An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:
Blower door test: $350
Duct testing: $100
HERS test: $375
HERS certification: $200
Infrared imaging: $200
The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency.
A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.
Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.
The three levels of home energy audits include:
Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.
Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.
Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
