I was recommended by an HVAC contractor for HERS test for an ADU. We had an issue with our contractor and had to fire him. I explained the situation to Anthony and he went above and beyond to explain the HERS testing process and even walked me through setting up an account with CHEERS. We would not have been able to figure it out ourselves and he was super helpful. I received a confirmation e-mail for my appointment, as well as a call the day before as a reminder. Alex called about 15 minutes before he arrived as a heads up. He arrived within the estimated window and was efficient and professional. I even received a receipt before he left. If you need HERS testing, look no further.

I needed a HERS Report done quickly on an old permit that I thought was closed out from a different company. They got me in quickly and I had signed up for a more expensive test, but they let me know that I didn't need that and charge me for the lower report. They were able to turn around the report almost instantly and stepped me through the Cheers account process. I literally couldn't ask for a better experience. Thank you ERE! I did see that they had a five star rating right now, but there was only a few reviews and sometimes that can be skewed. I do really feel like these guys earned it.

The owners Shawn was so incredibly helpful & knowledgeable. He came to inspect our property the next day. We pulled our permits as "owner builder" which was a hard project, but got through it pretty well. However, I had trouble understanding what this report was all about. Shawn totally gave me the rundown on how it worked, sharing so much information with me so I was able to comprehend what was needed. We had a lil hiccup with our report, it required our plans to be modified, which he took the extra steps to help us overcome. After a long season of working with many tradesmen, handymen, other workers, inspectors, ect.... I'm grateful to have had Shawn see us over the finish line. He's great, and I recommend him to anyone who has a project requiring a HERS report. Thanks again Shawn!

It never seemed to be balanced with the rest of the house so I called these guys in to find out what was going on. When they arrived we sat down and talked for a bit about the issue and anything else I might be concerned with. Then they started the process with some kind of high tech camera that looks through walls. They were able to spot the issue so quickly it was amazing. They pointed out exactly where and what needed to be fixed. A couple of days later I got a very thorough report with pictures and all the details we talked about that day. I would give them 5 stars but they don't actually do the repairs. They said being certified by the state as "verifiers" prohibit that. However they did provide a list of potential contractors to help. All in all the service was great and I was very happy with them.
