"Ezra and Charles are very friendly and personable. That is, when they want to take your money. What good is a 12-year warranty if you start ignoring your customers at 2 years. I needed my HVAC replaced. Because the HVAC sits on my roof, I decided to redo the roof too. Ezra and Charles came out and were really friendly so I immediately had a good impression of them. Even though it would’ve been cheaper to go with a roofer and a separate HVAC company, I decided to go with Landmark Construction Crew, aka Landmark Energy Upgrades. I figured it would be a more seamless process for one company to do both. I got this done in December of 2016. The thing with a roof is that you don’t know if it’s a good job or not until it rains so I waited to write a review. Around January 2018 ( a little over a year later ) we got some much needed rain but unfortunately, I had a leak coming from one of my vents. I emailed Ezra and he sent out a roofer. The roofer came, looked at the vent, jumped up on the roof for ten minutes and said he was done. Months later, it rained again, it leaked again, I emailed Ezra again. I decided to take a closer look at the vent and noticed that there was sunlight in the ductwork. I figured sunlight equals gap somewhere. When the roofer came, I told him and he said it’s nothing, probably just a reflection, without even taking a look. Then the roofer tells me that the next time there is a leak, I need to call the HVAC guy because it’s not a roof problem. I couldn’t believe it so I told him that HIS company IS the HVAC guy!! I used one company to do the roof and the HVAC so there is NOBODY else to blame. So, he jumps back on the roof and was done and gone in 10 minutes. About a month goes by and the rain is back and so is my leak. It’s 2019 so it rained a lot this year. Good for California, bad for me. So, I emailed Ezra again. After a few weeks, no reply. So, I email him again with pictures, a few more weeks go by and no reply. So, I call him and he picked up the phone. He sounded surprised to hear from me (probably didn’t recognize my phone number) and I start telling him about the leak. He said he didn’t get my emails but just text him my address and he’ll send somebody. A couple of weeks goes by and nothing. So, I text him again and after weeks and weeks of waiting, no reply. I’ve emailed, called, and texted so, at this point, it’s very obvious he’s avoiding me. If you are looking for a friendly company that is willing to take your hard-earned cash then Landmark is for you. But if you’re looking for a company that is accountable for their work then look elsewhere. I know I am."

Sunrun is leading the charge to create a planet run by the sun. We are building a more sustainable world, by making solar simple for over 200,000 customer's in 23 different states!

"Sunrun installed a bad roof on my house. After many months of emails and phone calls, they never sent out a repair man. Finally, under duress, I signed a form from Sunrun to use my own contractor. I signed under duress because they said they couldn't get a repair man and that this was the only way I could get my roof repaired, and there were driving rains. I told I didn't want to be personally responsible, and that's only thing I asked. But after the contractor fixed the leaks, there was more hidden damage that emerged and more leaks. They told me they won't fix the roof. The bad roof they installed was so bad that one company wanted to charge me $23,000 to fix it. He said the roof was so bad that really it should be replaced. And boy, when he looked at it, he sneered in disgust. Why did they not simply repair the roof after the first phone call. Eventually, they sent me an email with lies, such as "since the roof no longer has a running leak, Sunrun is not responsible for a repair." A blatant lie. I assumed this was an underhanded tactic written by a lawyer to fool the court in the event of a lawsuit. I thought Sunrun was a legitimate company. Even the Sunrun claims manager apologized to me for my treatment, and she said the higher ups were orchestrating everything. She seemed to be trapped in an immoral circumstance because the bosses simply wanted to get out of paying for that roof at all costs. Even from the beginning, they continually tried to get me to "work " with their contractor. They said they couldn't find the contractor and only that particular contractor could fix the roof. Why were they telling me all this. I told Sunrun, that I purchased the roof from them and to leave me out of such conversations. I truly feel this matter is about greed and avoiding the cost of their damage. They have a lot excuses, but I felt from the beginning, everything was a dodge or a put off. It's been two years and my roof still leaks. This is so cruel. I'm a senior citizen. The stress has been affecting my health and making me I'll."

Energy Efficiency Auditing questions, answered by experts

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

Yes, including optimizing settings and suggesting upgrades if needed.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.

If you want a new boiler that’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 “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.
