    I would highly recommend Felipe Sierra. I called him on Saturday and was almost sure I wouldn't be able to find anyone to come by and check our unit. I explained to Felipe that I needed someone immediately because we were leaving town and he agreed to come over the next day which was Sunday. He was prompt and very professional. He checked our unit and I felt he was very honest and his fee was very reasonable. Our unit was cleaned and he recommended we change the filter. Even though it was Sunday, I felt he took his time and explained in detail all we needed to know. With so many dishonest people in the world, it sure was nice dealing with someone as honest and kind as Felipe.

    My AC broke down in the hottest time of the summer...called phillip and he was here the next morning. He is very friendly and honest, changed the part and cleaned my AC. He worked quick and was very efficient! Happy to have found a very reliable person. I recommend phillip for all of your AC and heater needs.

    I have had 3 people come to try to fix my heater. Ive gotten answers to repair some parts all the way to replacing the whole unit. Phil did not change any parts he just cleaned the parts and didn't try to get me to replace anything. Its unfortunate we don't have more honest people like him. He did a great job and I recommend him to anyone looking to get work done on their AC/Heater unit. He made me aware of some parts that might fail in the future but did not try to pressure me into changing them. Thanks Phil

    I was having concrete in my backyard put in and I needed my air conditioner moved so In asked my brother in law and he recommended Phillip at Sierra air conditioning and heating. he had already worked on my brother inlaws house several times so I felt I could trust him. I realized he's a cool dude. his price was a little pricey but he does clean work and he stands by it. My AC actually runs better after he worked on it. (turns out it was a little low on freon.) He even did a maintenance for the furnace too while he was here. Im very happy.

    We called Phill and he was here the next day. My heating system had stopped warming the house and we did not want to wait until it got colder. Phill immediately knew what the problem was. My heater would come on but there was no air coming out. he replaced the fan motor that he already had in his van without having to make a trip to the parts house which saved us time.

    long story short, our heater is up and running and his price was very reasonable. hes very easy to talk to and informative. I was also impressed that he wore shoe covers to not get my carpet dirty. i really appreciated that.

    I can't say enough good things about phil. Ive been having him service my AC and heater since I bought my home in 2009. Ive recommended him to my family multiple times. he replaced the outside unit on my sisters house and fixed my moms furnace last year. His prices have always been fair too.

    I had the service technician, Phillip, come out to my house because my furnace wasn't working. He climbed into the attic and before I knew it, I could feel the hot air coming from the grills. He said the flame sensor was dirty so he cleaned it up. that simple. he only charged me for the service call. he did not try to sell me a new unit or tell me that I needed something I didn't. I will keep his number for future service. thank you!!!!!

  • Happy customer

    Extremely happy with the service that Phillip provided. A kind and honest man that did not try to sell me unnecessary service or part. However, he did give me the option to improve my air conditioning unit at a fair price. Thank you!!!

    Im very happy with the service and professionalism of sierra heating and air. After 2 companies were not able to find the problem, I finally called sierra air and phillip was able to repair my air conditioner, I will definately be reffering you to my friends and family.
