Every HVAC company I called either didn't answer or was booked out for weeks. AOL Heating & Air was completely different. Avi, the manager, genuinely cared about our situation and made sure a technician was sent out the very same day. Christian and his associate arrived promptly, were incredibly professional, and quickly diagnosed the issue. After multiple other HVAC companies told us we needed a brand-new compressor that would cost us thousands of dollars, Christian found the actual problem and repaired our condenser in just 30-40 minutes. Not only did they save us thousands of dollars, but they restored our air conditioning and had cold air flowing through our vents again the same day. Their honesty, expertise, and compassion are hard to find these days. If you're looking for an HVAC company that truly cares about its customers, provides honest assessments, and doesn't try to sell you repairs you don't need, AOL Heating & Air is the company to call. Thank you, Avi, Christian, and the entire team, you turned an incredibly stressful situation into a huge relief!

He was professional, extremely quick, efficient, and thorough from start to finish. Dryer Vents Express did a flawless job removing the significant buildup of clogged lint from our dryer vent, which has made a noticeable difference in our dryer's performance. Our dryer now dries laundry much faster and more efficiently, which should also help conserve electricity and reduce unnecessary energy consumption. I highly recommend Dryer Vents Express (Carlos and his team) to anyone in need of professional dryer vent cleaning and maintenance. Outstanding service, excellent workmanship, and truly exemplified customer service!

I chose Dryer Vents Express based on their positive reviews and they did not disappoint. Carlos was very quick to respond and sent over two of his guys the very next day after I initially sent the online request for a quote at 9pm the night before. They were very professional and efficient and just after a few minutes of starting the job, they were able to remove so much trapped lint including a huge strand of lint that even shocked them. They continued to remove a bunch more lint and cleaned up everything once they were done. The price was very reasonable and will make sure to schedule with them every 6-12 months to make sure my dryer vents remain clean! Thanks guys!

Leo was amazing! First off, when I called Leo's Home…read moreSolutions, they picked up the call right away and were able to give me 2 appointment options for a specific window of time for the next day! Leo was very thorough and professional, after the walk through consultation and then proceeding with a protocol and solution, I felt much more at ease & safer with his expertise! Calming my completely freaked state of mind! He found 2 openings on the exterior of my house and fixed them: put a screen over the exposed gable vent, quickly & impeccably, as well as covered an open vent pipe on the roof Also, as I was scrolling through all the exterminator options, I realized I didn't want a van that screamed exterminator in front of my house! Besides the name "Leo's Home Solutions", being nicely "general", I got a great feeling of the work Leo's company could provide from the glowing reviews and I was right! Everything was at an extremely fair price too! I highly recommend Leo's Home Solutions!

Leo and his team at Leo's Home Solutions came out and did one hell of a job. Their team was incredibly coordinated and completed both the crawlspace and attic in a single day. The attic didn't have any infestations, but they carefully identified potential entry points and blocked them off to help prevent future problems. In the crawlspace, they completely removed all the trash and animal remnants, including droppings, then sanitized the area with a lemon deodorizer and bacteria-killing treatment. They also fully replaced the mesh lining on the vents surrounding the house, including both the crawlspace and attic vents. Within a couple of days, the flies were gone and the lingering smell had cleared up. What I appreciated most was that Leo was responsive, straightforward, and willing to fully address an unpleasant problem rather than just putting a temporary band-aid on it. The price was fair and reasonable considering the amount and quality of work his team put in. Crawlspace and animal-related problems are not something you want to deal with, but Leo made the process much easier. I'd recommend Leo's Home Solutions to anyone dealing with crawlspace odors, animal intrusion, cleanup, sanitation, or sealing work.

I used Elite Air for a dryer vent cleaning and had a great experience. My tech, Ido, was super…read morefriendly, fast, and really knew what he was doing. My 3-story vent ended up being more complicated than expected, but he explained everything, got into the tight attic space, and handled it like a pro. The price did go up because of the extra work, but he was fair and worked with me. Everything is running perfectly now. I'd definitely use them again and recommend asking for Ido!

I normally don't write reviews, but this company's service was so bad that I feel obligated to warn…read moreothers. 1. Late and unprofessional arrival The technician called at 11:33 am and said he was 15 minutes away. At 12:30 he still hadn't showed up so we called him. He said he called us by mistake and meant to call another client. He then said he would be at our house in an hour. At 1:52 PM he called saying he would arrive in five minutes. At 2:02 PM I looked out the front door and noticed he was sitting in his van. At 2:03 PM he simply drove away. When I checked my Ring camera, it showed that he pulled in at 2:00 PM, took his ladder out, never knocked on the door, then put it back and left. We called him immediately. He claimed he knocked for 5 minutes and "no one was there," and said he would turn around. He did not. We called the company and were told he would come back shortly. He finally returned 25 minutes later with no explanation. 2. Bait-and-switch pricing I was quoted $199 for negative air cleaning of vents and returns. The technician looked at the vents and told me "negative air does not actually clean," and said I would need a different cleaning. He quoted $1,200 -- then said they were "running a special" and could do it for $800. When I questioned the price, he then offered a "final best price" of $600 to clean just two vents. No special materials, all manual labor. In other words: massive upsell and pressure tactics. 3. Unprofessional attitude When I refused service and told him I would not be paying more than the quoted $199, he told me he had "driven two hours" to get here, as if that justified changing the price on site. I told him I don't appreciate bait-and-switch tactics. After this experience, it was clear they rely on deceptive pricing and hope customers will cave in. Completely unacceptable. If you want honest, professional service, look elsewhere. This company wasted my time, was dishonest about pricing, and showed zero respect for the customer.
