    Fraud via shortcuts.
    Mike R.

    STAY AWAY! Sneaky and dishonest! We hired Jensen Mechanical to install an AC system in our home. Their bid wasn't the cheapest, but the owner seemed trustworthy, at least initially.. He turned out to be a total cheat and the job was a disaster. It took a month to finish instead of the 3 days we were told it would be, the owner completely screwed up getting the proper permits with the city, lied to us repeatedly saying everything was in order, dragged his feet fixing his paperwork problems, and then argued with the inspector's safety requirement to bolt the AC unit into our roof beams. After refusing to comply and causing even more delays by trying (hiring a consultant) and failing to convince the inspector that the bolt the unit into the roof was unnecessary, he crew ultimately "faked" bolting the unit down to pass the final inspection from the City. Throughout the whole mess, the owner, Ryan Jensen, refused to actually take responsibility for his mismanagement, although he sure could run his mouth with excuses and blaming other people for things that he did wrong. We didn't know the full extent of the lies until we checked this "bolting" after the final inspection. The bolts did go into the wooden AC unit base, but were too short to go all the way through the roof surface and into the roof beams, which is what the inspector had stipulated. (A photo is attached.) Their plan was probably for us to never find out -- but one of his crew admitted that "the bolts are only for show" -- while he stood in front of our front-door home security camera! Now we have a project that is not up to permit standards and serious concerns about what other shortcuts were taken during the install. Is the wiring safe? Were proper materials used?. What Ryan Jensen did was outright FRAUD of a private consumer and to a governmental authority. He has been contacted by our attorney, but has not bothered to reply. Perhaps he is too busy cutting corners and defrauding his next customer. We have video and photo evidence to support our claims, and we will be filing complaints with the CA licensing board, with the Better Business Bureau, seeking remedy with his bond company, filing for actual and punitive damages in court, etc. If Jensen Mechanical was this brazen about lying to the authorities and taking the cheap way out in our case, what other undiscovered shortcuts have they have taken on past jobs, and what will they try to sneak past you if you hire them?

    Thank you Ryan, my tenant also thanks you !

    I was a new homeowner in 2022 when Vic (the owner) and his company, Elite Comfort Systems, saved my…read morefamily (including the feline members) from sweltering in 100+F degree weather by diagnosing and repairing my air conditioner. Since then, they've serviced the almost 22 year old system at my home, nursing it along. With each semi-annual "check-up" service, they advised me on what I needed to do, and what could wait. When funds were tight, they suggested stopgaps to help. Because of this history, when Alex showed me that my heater was leeching carbon monoxide into my home, I knew I could trust him. While I waited for my appointment, I was provided with space heaters gratis. This IS an independently owned business, and they treat customers like family. Ozzy (Osvaldo) and Anthony installed a new heat pump and air conditioner for me last week. They were at my home three days. Not only were they professional, friendly, and polite, they were also respectful of my home--taking time EVERY day to cover my carpeted areas, covering their boots as they came into and exited the house, and cleaning up any installation debris before they left each day. Ozzy and Anthony discovered that a part of the original system was not going to work as efficiently with the new system (the dampers) given the difference in the size. Ozzy explained the difference to me, noted the cost, and the pros and cons. He didn't pressure me to upgrade the items but he made sure I had enough information to make a decision. At the end of the installation, Ozzy took the time to show me how to use the new digital thermostat controls and gave me tips on how to use the system economically. He provided me information on how to follow up if there were ever any problems. Just like other times, Vic called a few days later to see how things were going (I missed the call, but still...so so kind and thoughtful). It's a lot of money to replace your entire HVAC system, no matter which company you use, but hiring one where you know you can trust the company. Simply put, you'll never have worries about trusting Elite Comfort Systems.

I found this company based on all the wonderful Yelp reviews to tune up my old gas furnace- something I do every year before the winter season to ensure optimal maintenance. They came out and immediately refused to do the service citing possible asbestos tape. I asked how this was possible when the last 15 years I've gotten service and have even asked the contractors to do a visual inspection of my system. They weren't sure but said that another employee in the area can come look and give me an estimate for a new system. I thought this was shady and it turns out, I was 100% right. They came later that day and quoted me $26K for a new system not including subcontracting to get the asbestos removed (another $1500). I was told and shown pictures that there was evidence of the same tape inside the duct work. I was told I would get these pictures sent to me with along with the estimate but never received any of them. I got someone to come out and test a sample of said material for $100 which did come out positive for asbestos. However the only asbestos that presented any harm was the tape on the outside of the system. There was no asbestos inside but it was recommended that I do more expensive air testing since Perfect Star said I would not be able to use my heater without the asbestos getting released into the air. Not only was this stressful to hear right before the cold weather, but I was very concerned that over the last decade I had inadvertently put my whole families health in danger using this furnace. Meanwhile, Raymond Kinder texted me a few days later to find out if I was going to move forward with the new unit. I told him asbestos removal was my priority. His response via text was "if they remove asbestos, you will not be able to run that furnace as the gases will not be vented out properly." This was not true. After several weeks of not using my heater and exploring other options to deal with a pretend problem they created for me, I went with Air Quality Testing who charged $540 for an air test. $640 later along with having no use of my heater, I learned that there is no asbestos running through my air or ducts. Perfect Star literally lied to me in order to attempt to get me to drop nearly $30,000 on a new system. Stay away from this company! They do not deserve your business for lying to their customers.

During the estimate phase, Constantine was a breath of fresh air. Instead of pushing generic upsells, he actually "downsold" us by engineering exactly what we needed to work seamlessly with our home's downflow ducting. He was honest, straightforward, and clearly explained the system without any high-pressure sales tactics. For the installation, Mike and Diego were our crew. They arrived a little past the initial 9am window on the first day, but they worked incredibly hard and got the entire complex job done right on schedule. At the start of Day 1, I handed them a simple "homeowner's QA" list of things I wanted to check with them at the end. They were super nice, listened, and gladly accommodated every single request. The workmanship is top-notch. They perfectly sealed the exterior wall where the lineset exits, helped me get the Kumo Cloud Wi-Fi connected to my phone, and hauled away all the old debris, leaving the site spotless. As a testament to their technical skill, when I asked about the refrigerant line vacuum test, they had pulled it down to 350 microns--which is a great number and proves they don't cut corners! Pics attached of the final setup. If you want an HVAC company that is honest in the office and expert in the field, we highly recommend the Galaxy team!
