Signs You Need AC Replacement in Los Angeles ?
Don’t know when it is time to change your air conditioner? The most frequent warning signs are the following:

Hired AOL to replace our old condenser and gas furnace with a new heat pump and air handler. Their quote was very competitive and though we ended up having to go with a more expensive unit due to size constraints and other reasons the total was still very reasonable. They did a great job and were responsive whenever we needed to get in touch. Can recommend.Posted on Google Roxana ZybleTrustindex verifies that the original source of the review is Google.

EXCELLENT Based on 210 reviews Posted on Yelp Jeff R.Verified Called AOL on NY Eve for my Dad's house in Granada Hills (I live out of town) ...he's elderly and his Caregivers told me the Heater comes on but the house isn't getting warm. Lisa answered the phone and checked the schedule to see if they could come out the same day....within 30 mins she told me Joseph can stop by...he then called me and told me what he needed to to, he did have to go back to his shop to get a part he returned to install it and replace some old wiring. He tested everything out and within 3 hours from my first call the house was warming up again. We found the cost to be reasonable and are quite happy with the service. I would use them again and can recommend AOL too. THANK YOU!Posted on Yelp Josh B.Verified Highly recommended. 3rd company that I worked with and by far the best. Dean was on time, communicative, walked through the issues ahead of any servicing. Identified a critical CO2 leak issue that was unrelated to what I called about. Will definitely lean on them for any future HVAC needs.Posted on Yelp Jonathan A.Verified I called AOL on a Saturday afternoon, when my AC failed during this record heatwave. After some initial troubleshooting over the phone, Avi & Jose arrived the following morning and completed the repairs in 2 hours, despite some challenges. My AC compressor is a high-efficiency unit with some complex electronic circuitry. Avi & Jose have particular knowledge & experience with these models, fortunately. I appreciated their professionalism, availability, and quick response!Posted on Yelp Glenn B.Verified Promp, knowleagable, neat and courteous. Avi and his crew were terrific. I had a lot of choices... I'm so glad I chose AOL Heating & Air. They will be my go-to for my service needs. Highly recommended!Posted on Yelp Reed M.Verified Avi responded promptly to our call and came to our house the same day. He explained the quick fix and its disadvantages given the short useful life of our system( which I had previously researched and which was confirmed by multiple problems we had in the 7 years we owned this house). He gave us a very fair price for replacing the system without any hard sell, which we chose to do. The team came the next morning and had the old system out and the new one installed in 6 hours. They were professional, polite, clean and quiet. Avi came by mid-day and two days later to check the completed work (the intervening day was a religious holiday). Altogether a 5 star experience.Posted on Yelp Sally N.Verified Avi is the man!!!! He is a super nice person and knows his stuffs. Our Condenser went down and I cannot afford to replace a new system. He found me a way to get a new condenser and coil with very very cheap price. We never met before and this is our 2nd time doing business with him. He treats his customer as a friend rather than as a contractor. We are so lucky to find a reliable hvac contractor and he is a man of his word!!Posted on Yelp Darren W.Verified AC stopped blowing cold air on Saturday of a major heat wave. They came out by early Sunday morning and fixed the system in 30 minutes. Super responsive and saved the day! They were responding to every AC emergency on Sunday when other companies said they couldn't come out until later in the week. If there were 10 stars I would give it to them. Thank you AOL!!!Posted on Yelp Melanie T.Verified Avi is the best. Great prompt service. Highly recommend. We were totally without AC and he he fixed our problem.Posted on Yelp Yadi S.Verified I was told during my last AC maintenance that our system was very dirty and needed a deep cleaning so that our system could operate efficiently. They provided a quote... and I was stunned at the price AND how many components needed cleaning! Decided to check Yelp for reviews and AOL stood out. Reached out to AOL and Joseph came out at the end of day to review our needs. I decided to hire them and couldn't be more pleased. They arrived on time, Jose greeted me upon arrival. Both Jose and Carlos were very professional and answered my questions during the service. I highly recommend AOL and plan on using their services in the future.Posted on Yelp Peter S.Verified AOL installed 2 new mini-split systems. The old ones were installed incorrectly, and they explained why and provided a few options on new systems and installations. Very good communication and service!
