    This is a scam. They want you to pay $40,000.00 for windows that you can get for $4,000.00

    I was prepaired for the worst, and was pleasantly surprised with the sales pitch and demo after seeing the product inside and out.

    Jason tested our new ducting and discovered that our intake box was leaking air from the attic at a…read morerate of a small bedroom every 10 minutes. WOW. So in the summer, instead of sucking in air from the inside of the house, it would be be sucking in 100F air from outside, making the AC inefficient. He took the time to drive to the store to get sealant to fix the leaks inside the intake box, and spent an hour applying the sealant himself. Did not ask for any extra money, did not complain, had a great attitude, and really wanted to make sure that he gave 150% effort to the customer. Then he re-tested the system and the system passed this time showing barely any leakage. Gave us the report and the paperwork needed for the building inspector. If you do your own HVAC upgrade without a city permit, you think you save money by not having to spend money on HERS testing. Nothing could be farther from the truth. When it comes to spending money, I'm cheap. I didn't realize that Jason's job is to make sure that the extra money you spend on upgrading your ducts/AC equipment to more efficient equipment is not in vain due to leaks in your ducts A+++ experience with using this company for HERS testing, and will recommend to others to use this company.

He came with the proper equipment to take accurate measurements, and generated a comprehensive report. He was very efficient. Furthermore, Jason had the HERS report sent to the City of Lake Forest electronically, so the city inspection went very smoothly. Great value for the services they provide, not only for the testing, but also for the reporting to the city inspectors. I highly recommend Jason and Reliance Energy Services. Thank you, Jason.

    Before I share my experience with Synergy, allow me to preface it with a brief summary of my…read moreexperience with the first company which was assigned to our case. I won't mention their name because they *did* successfully install a new water heater, but our experience surrounding a furnace replacement was so ridiculous, I wanted to let others know how bad things can get if they end up with a company that's essentially the opposite of Synergy. The process with the former company began in early August of 2025. Between then and late March or so of 2026....which covers EIGHT full months, mind you....they dragged their feet, twiddled their thumbs, and kept sending people to our home over and over and over on a seemingly endless loop to keep doing an "assessment" and taking the same measurements, again and again. When an installation date was finally set, alarm bells rang and red flags waved when the installer asked me to confirm the dimensions for the attic entrance. Again. For what had to be the 6th time. I obliged. His response was "Oh, this won't fit. But we'll try anyway". Excuse me, what? The math wasn't mathin and the logic wasn't logic-ing. The fateful day came and two guys unloaded it and said "we know it won't fit but we were told to try anyway". So they dragged it inside, tried lifting something several inches too wide through an entrance several inches too small, confirmed it wouldn't fit, apologized, and left. Shortly thereafter I received a call from either SoCal Edison or SoCal gas (whichever of the two it was) informing me that the contractor was unable to complete the service, and to please re-apply to the program again in order to move forward with another contractor. After much internal screaming and cursing I reached out to a small army of people. When all was said and done, I was able to reach someone who heard the whole tale and proceeded to arrange a new contractor, this time with Synergy Companies. The first contractor who came by, Brandon, was super nice, polite, respectful, and patient. He made his way inside our attic and was met with an HVAC nightmare. The home was built in the late 50's and everything up there hadn't changed much since, with a broken furnace and duct work from the early 60's. He made a phone call and explained the situation with another associate, and left very likely hoping he would never have to set foot in the home again. Unfortunately he did for a second follow-up assessment with someone else, but he remained as professional as ever. He informed me that the final call would fall to a gentleman by the name of Bryan who ultimately had the last say based on the photos and job details. I reached out to Bryan a few days later and was relieved to connect with someone so on top of their A-game, I actually believed things were headed in the right direction, and I wasn't being met with a load of hot air...so to speak. They actually had a unit that would fit and they clearly knew what they were doing. The difference between the prior company and Synergy was absolutely night and day. And on top of it all, their professionalism is unmatched. Bryan in particular was such a breath of fresh air (I am not trying to be punny, don't judge). Things were actually happening now that I was working with the right company. After a bit more back and fourth, a date was set, and Bryan along with Brandon (I'm so sorry, Brandon), and a third gentleman, Hector, arrived bright and early at 9am....ready to descend into the the void that is our attic. This valiant trio knocked it out in a day. ONE DAY. And let me tell you, that was no small feat. The house is cursed, but that didn't deter them. Brandon, Hector, and Bryan were miracle workers. Flat out. I'm still in awe several days later that it's DONE. They had already gone the extra mile and then some, but Bryan ended up going even further after the fact, when a new unforeseen development arose. My FIL finally had a new furnace....but he also has dementia, and he started flipping the switch by the attic to turn it on and off instead of operating it from the wall mounted controls, or phone app. Both of which are too confusing for him. And flipping the switch like that not only potentially hurts the unit, but means we can't control it on our end through the app to ensure he's comfortable. I let Bryan know what we were now contending with, and he voluntarily offered to personally come BACK the following day and re-route the wiring directly to bypass the switch, so my FIL can flip it all he wants without it being to his detriment. To whomever is above Bryan - GIVE THIS MAN A RAISE. And while you're at it, do the same for both Brandon and Hector, because they are awesome too. So there you go. I can't recommend Synergy enough. Even if they do half as much for you as they did for us, you'll be impressed and highly satisfied. Their business tagline is "We treat people right". I can confirm that they sure as hell do.

He answered all my many questions, showed me the old parts he removed, and provided a photo of the work he did below my house. I really like that he wasn't pushy and explained most of what he was doing as he was doing it.
