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.

I would definitely recommend.

My 86-year-old mother lives alone and recently told me that her house has been freezing for months. Because I do not live close by, I sent an HVAC serviceman out (from another company) to look at her system. After seeing pictures of the attic and HVAC components, it was clear that she needed an entirely new system, including air ducts (which had decayed through the years) and she needed additional blown-in insulation to reach an R30 factor. Using Yelp and other Google searches, I identified four HVAC contractors in her area. Two of the four estimators were arrogant and had trouble answering my questions over the phone. They spent most of their time telling me how good their companies were and how bad the competition was (even though I did not give them their names). The other two contractors, one of which was OakRidge Energy, seemed very experienced. Both were very kind to my mother and were very professional with me over the phone. The two arrogant guys provided ridiculously high quotes. The third was quite a bit less. OakRidge provided the best price and threw in a free "before and after duct pressure test." My mother was so happy that I had chosen OakRidge Energy because she "really liked the guy that came out to estimate the job." We signed the contract on a Wednesday, the team arrived on that Friday, and they had the entire job completed by 3:00 pm that Saturday, just three days after signing the contact. The office team, Rebecca and Hannah, were excellent as well. They were always available, pleasant to work with, knowledgeable, and very responsive. And the owner, Chris, responded to each of my technical questions, via email, in minutes. Although I did not meet the installers, my mother, sister, and brother-in-law did. They were all very impressed with how Armando, Carlos, and Cesar went about their business. They were very pleasant, were very clean and organized, knew exactly what they were doing, and seldom took a break. I asked my sister to look over the review that I had written. Here is her response unedited.... "Randy that was PERFECT! They were amazing & so professional. We all felt so comfortable with them that Mom went away for the day and Phil & I sat downstairs. Never once did we feel we needed to stand over or watch them, it was weird how much trust we had in them they just came across as hard working, honest guys and they truly were. We really got lucky with them and trust me Mom is warm up there." I strongly recommend that you ask OakRidge Energy to provide an estimate for a home energy survey or an HVAC system upgrade, if needed.

RKM reached out immediately and sent Technician Ruben. From the moment Ruben arrived, he was courteous, professional, and respectful. He thoroughly diagnosed the problem, explained everything in clear, easy-to-understand terms (no technical jargon overload), and got right to work. He replaced a faulty capacitor and performed a full system check to make sure everything was running perfectly. The repair was completed efficiently, and my AC is now blowing ice-cold air. Ruben even took the time to show me a couple of maintenance tips to help prevent future issues. I'm extremely impressed with his knowledge, speed, and friendly attitude.

    We had Tim from TopNotch Energy Compliance Services come out for a full home energy assessment…read morebefore moving into our new (to us) 1963 house, and it was honestly one of the most useful parts of our whole renovation process so far. Tim spent two full days on site running a blower door test, duct leakage test, thermal imaging, and smoke diagnostics, and he walked us through everything as he went so we actually understood what he was finding and why it mattered - not just handed us a report full of jargon at the end. He caught things we would have completely missed, including flagging that our existing 5-ton AC system was likely oversized for the space it's conditioning, which turned into a whole important thread in our renovation planning. What's stood out most is that he's kept answering our follow-up questions after the visit, even though the paid assessment was long done. Because he's independent and isn't trying to sell us ductwork or a furnace, we've trusted his read on things more than any of the contractors who are also bidding on the work - there's no incentive for him to tell us anything other than what he actually sees. That kind of honesty has been rare to find in this process. If you're buying an older home or planning a renovation in the Inland Empire area, get Tim out before you sign off on any HVAC or insulation work. Worth every penny.

I tried to have my Home Warranty work on this issue last year, but the contractor kept insisting that I needed to hire a contractor and make sure that he had a skinny employee on staff. Well Intelli-HOME Energy ended up being a savior. With the evaluation it was determined that my bedroom alone was receiving 1/4 of the air conditioner air flow. No wonder last summer I froze and my roommates we over heated. They came in and determined that the previous owners contractor had left the old ducts in the attic from the remodel and Intelli-HOME Energy removed both sets of ducts and put in new ducting work along with more insulation. The true test comes in this summer when the heat is on and how cool will the house stay and keep my energy cost down.
