    Our new furnace, installed by Luis
    Angella A.

    I highly recommend! Mauricio and Alfredo responded to my quote request right away and did a great job of pitching my business. Straight hustlers! They mentioned they were in the area and could come over, and I decided to take a chance with them. Our furnace broke on a Monday afternoon and we had a completely new system by Tuesday night. Alfredo and Mauricio explained what they could do and out of safety reasons they recommended we completely overhaul our system with a new furnace and air ducts. I didn't feel like they were trying to upsell us to make unnecessary repairs so they could earn more money. In fact, they were very clear I could spend $$ to patch the problem temporarily, but eventually we would have to spend $$$$ for a proper replacement anyway. Our furnace was super old and the ducts were leaking, on top of that not properly installed by the previous owner. Luis did most of the heavy lifting and I've never seen a man work so hard in my life. We had to encourage him to take a break and offered him food and coffee! I would have been fine if they had to come back and finish the job on day two but Luis was insistent on powering through. He did a very meticulous and clean install. The price they quoted us was reasonable compared to other vendors I spoke with. We will probably call these guys again when we need to replace our hot water heater.

    ASM responded quickly and serviced our gravity furnace in the middle of winter when we sorely needed heat. I highly recommend them.

    I live in SF, and no one would come out to the city last minute but Alfredo showed up in about two hours.

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.

    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.
