They installed our new A/C unit correctly and came out to diagnose an issue that arose two years later. They didn't waste our time and got it right. Thank Zack & Company. We're feeling really cool again. read more

Rashad and EVERYONE at Omni Air are amazing. They have taken care of us for a couple of years. This year, we had to get an entire new system installed and they were timely, efficient, and knowledgeable with the installation. Their work is immaculate. All of the crew -and Anna (who schedules and keeps the operation running), are all kind and caring. I highly recommend this company for all of your HVAC needs!! read more

We had a heater problem messaged couple of hvac guys. Zach replied quickly. He was very helpful and honest with our heater problem! They came in a timely manner. He made some good recommendations and told us how to prevent the problem from occurring again. Friendly and trustworthy would recommend! read more

We are so impressed with the responsiveness and the ability to listen to customers needs. Yesterday we called and Anna was able to set a appointment to come and see us at 8:30 next day. Our heater stopped working in Long Beach. The temperature in the house was 59 degrees, and we were freezing inside. The representative Jacob came to evaluate and determine why the heater would not turn on. He determined there were a lot of problems with a 41 year old heater. He explained he could fix the heater but he explained we would spend more money trying to fix other things because the system was so old. We agreed and decided to buy another heater. Jacob told us they could install the following day, so that meant we would be cold again tonight. Today Anna called and asked if we wanted to have them install today at 3:30! We were so happy to hear their crew had finished a job and was able to install our heater a day earlier than expected. Rashad and Armstrong arrived to disconnect the old system and prepare the work so the new heater could be installed. When they finished the second team arrived with all the new equipment and heater. Robert and Christopher arrived to finish the install, they hooked up the system and finished tonight at 7:00. Omni HVAC is the very best! We couldn't believe how they went above and beyond to make sure we had heat tonight! If we could rate them a 10 star we would! Outstanding, excellent service from the initial call to the completion of the project! Wow! This company and their employees are exceptional!! read more

Highly recommend OMNI HVAC. I called them to schedule some standard pre-winter maintenance and they offered me a free smart thermostat without my even mentioning the promotion. A couple days after they installed (which was really fast), I messed up and didn't properly close the door - causing the heat to not turn on. I called them, and they had someone come back out within 40 minutes. read more

Did our a/c stop working in the hottest day of the year so far?! Of course it did! I called Omni and they were able to schedule me for the next day. Harri came out and determined the cause immediately. He replaced the broken component, and sweet relief! The air blew cold again. I felt the price was fair. Omni will be our first call next time something like this arises. read more

My central air was 25 years old, and it was time for a new system. I shopped around for a while and Omni Air was the one I chose. From quote to purchase to installation to service "excellence". All I can say "they were very professional" read more

Hari was super professional explaining the issue and what need to be done very honest I will definitely recommend and call again and most importantly thing was the arrive in 1 hour was very quick!!! read more

Stay far away from these guys. So many better companies to choose from and unfortunately i learned the hard way. Installers are horrible and they will not stand behind their crappy service. They will blame you for their faulty product and service. read more

Key point 1. They are honest, don't try to sell stuff you don't need 2. They care about your home, cover carpet and all area they work in, and even vacuum for you 3. They are efficient, all crews are good friend, it's one of those companies people enjoy working in. 4. They go beyond construct scope, do extra to make your life easier 5. Shout out for veteran owned business! 6. With them, you are in good hand read more

I scheduled a maintenance for my home furnace, which was located in my attic and got Jakob as my tech and another tech( didn't get his name) . And they were great guys. They arrive exactly on time and were informative and quick and fast. After the service maintenance, they provided me a checklist of all the things they did so I am kept up to date and also had some recommendations for the next maintenance that i will surely like them to do. They even stayed to clean out the vent filter and kept everything as clean as possible. I had some more questions for my outdoor AC unit and they were more than happy to answer my questions. 5/5 service . read more

Other HVAC companies better start taking some notes, OMNI air HVAC is the Shohei Ohtani of HVAC companies!!! My AC unit was not working after the natural gas was restored to my condo community and condo unit after having no gas for the last few months of summer 2023 due to old faulty gas pipes that needed to be completely replaced. The SoCal Gas Company techs went to inspect the furnace and other natural gas-powered appliances before restoring natural gas, but they didn't communicate with me the state of my furnace. 3 weeks later, I couldn't handle the heat anymore, so I did what I always do when I need help with maintaining my condo, I hoped on Yelp and searched for local HVAC companies. I called OMNI on a Saturday afternoon, and Anna I think, was the one who answered the call. She answered the call right away and scheduled me in for Monday morning. Robert and Armstrong were the techs who arrived on Monday on time at 8:30 am with dark blue boot covers. They were quick to diagnose the problem and gave me a proposal to fix and do future preventative maintenance on my HVAC system. The indoor universal blower motor failed due to lack of maintenance, Robert and Armstrong replaced it with a new one. Robert suggested to go to the furnace unit with him so that he could explain to me what he was doing, and so that I could learn how to do the maintenance on it to save myself some money, who does that nowadays!! Robert educated me on how lack of maintenance on the furnace can lead to fatal carbon monoxide poisoning and is a potential fire hazard. Robert and Armstrong finished the job on my HVAC unit in 2 hours. After they finished the job on my HVAC unit, both of the guys cleaned up the area that they worked on and left it better than when they came. See you in a few months Omni for the summer maintenance on the condenser ac unit on the roof. If you are still looking for an HVAC company, stop here, hire these guys, it will be worth your hard-earned money. read more

I'm an electrician by trade so I don't really work on AC units much, but I thought to give this company a try. They sold us on a capacitor that was maybe valued at $50 and charged $500. Then tried to charge a couple hundred more to clean the AC unit. Literally just to take leaves and dust off. Then tried saying we needed a new AC unit for $10,000-$15,000. We hired another company to come out and assess their findings... Turns out everything was fine. I'm sure they have helped some people, but they have also taken advantage of so many others. Shame on this place. I recommend that If you hire this company and they suggest something needs replacing, please get a second opinion before committing with them. read more

Jakob at Omni was great. Very professional, courteous and knowledgeable. Omni was called out to do a Bi-Annual maintenance on by heater. I just recently hired them for this purpose. Jakob found that when the HVAC was originally installed they failed to install two very important safety shut off valves and gas filter. He was able to remedy this and in a very short time the maintenance and repairs were done. I feel much safer using our HVAC now. Twice in the last two years I have had two different companies out to inspect the HVAC. Neither company took the time to inspect as thoroughly as Omni. If they had they would have found these problems. Neither of them were hidden within the unit. Thank you Omni, see you again for the summer maintenance read more

My family and I value Omni Air HVAC of Orange County very much. Excellent customer service and an exceedingly kind and knowledgeable staff. Delighted in a our purchase and investment...a superior furnace. I was educated about carbon monoxide escaping into our home. Omni Air HVAC with determination removed and installed a new system within 4 hours and additionally cleared our vents. I highly recommended Omni Air HVAC to those who seek a fine product and partnering team. read more

Absolutely phenomenal response time with this company ! I called at 8:10ish am on a Thursday morning because my mini split was leaking and I didn't want it to cause any water damage. They had a technician at my home by 8:40am!!! That was my first wow factor Rob and Abraham were able to quickly determine that my drainage had been clogged and were able to get it cleared right away. They were super helpful and informative on how to prevent future drainage issues with my system. Definitely recommend these guys read more

Jakob who gave us the estimate was very professional and informative. I Don't know much about AC installations, but Jakob answered all my questions and was super helpful and very knowledgeable and able to help me understand the process of the installation On the day of the install Rob, Abraham, and Nathan showed up and were awesome. They finished the install within 5 hrs ! Not only were they fast but super detailed on the install ! I had my AC back in order to beat this hot Anaheim heat ! read more

Omni Air HVAC is a true professional in the field, if you're looking for a company with integrity and great customer service and reasonable price this is the right place. Great company and super fast response time. This company will not gouge you with false upgrades. I will be using them from here on out. Thank you!! read more

Harri, the Omni technician was prompt, courteous and very knowledgeable. He diagnosed the reason why the system quit working and had the correct part to fix the problem. We would use Omni in future. read more

Harry was extremely, helpful, knowledgeable, honest and he arrived 5 minutes before our appointment time. I will definitely use Omni again and I would highly recommend them for service. read more

THIS is the HVAC company to call when you have to replace your OLD, rusty... 1979 AC unit top to bottom. I called several companies in the area that declined the job because it was either above their skill grade or they couldn't handle the work. Greg from OMNI came out and was honest, upfront, didn't upsell me, and told me the truth about what I was looking at - regarding my install. He came up with several creative solutions for me to look over and to choose from. I appreciate so much the initial quoting effort, then how much work they put in to make sure I have AC for the summer. The install for these guys has been grueling, but not a single installer has complained. They're all smiling, all super kind, and I trust them in my home. This company is top notch. The pricing is competitive, the effort that goes into finding a solution for a sticky and hot situation is untouched, and the install overall has been efficient and has not impacted my schedule. I appreciate the honesty of an HVAC company. Where I feel I could have been price gouged, I received a really honest, competitive quote that was a no brainer to select. Will continue to use OMNI for years to come. HIGHLY recommend. read more

My AC went out during the heat wave. I was very impressed by their service. The person that scheduled my appointment tried to get an appointment the same day but everyone was on call. She called later that day and I was scheduled the next day. The technician arrived on time and change a part that was not working. He was very professional and pointed out some maintenance issues but he didn't try to sell me on a new AC or service which I greatly appreciated. I asked about cleaning out the vents and he said that his company does offer that service. I definitely will call him for future maintenance. read more

Honestly, this company is simply amazing. If I could give more than 5 stars I would. They really go above and beyond with their service. I've spoken to a bunch of HVAC companies to get my 1984 condenser replaced and none of them have been as kind and genuine as Omni Air HVAC. Greg has been helping me with my project throughout the process and has been a key reason why I decided to go with them. He takes the time to explain everything to you to ensure that you understand. In addition, he also gives you the various options and opinions but really shows that he cares about what you want since ultimately the decision is ours. Alex and the 2 other guys that came out to install the condenser and coil showcased that same genuine interaction. They were respectful of my space and thoroughly made sure I was pleased and informed. Huge shout out to them. Overall if you need any HVAC services, I HIGHLY recommend you connect with Omni Air. read more

We needed to get our ducts replaced after going through an asbestos abatement and after getting some quotes from different HVAC companies, we went with Omni Air HVAC. This team is the best and we had a great experience working with them! I worked with Ethan to get a quote and he was very responsive through text to help schedule the ducts replacement. We ran into a lot of scheduling issues with our asbestos abatement team, but Ethan always tried his best to figure something out and get us scheduled. When the day finally came to get our ducts installed, we were greeted by Rob, Armstrong, Nate, and Christian. These guys did an amazing job installing the new ducts and they were really respectful of our home. They were friendly, polite and did a great job cleaning after themselves too. We finally have heat and it's all thanks to this team . Don't hesitate to reach out to them if you need any HVAC work! read more

We received a call from our guests at our airbnb property that the air conditioner had gone out. It's an older home & as luck would have it the weather was expected to be 90 degrees. We were very pleased that Omni air arrived at the property and diagnosed the issue, fixed the problem and had us back up & running in less than 24 hours with ice cold air. Would highly recommend! read more

These guys were awesome, needed a simple ducting repair and they gave me a reasonable estimate. As they were there and working on the project, they addressed a bunch of other AC needs, installed a pump on the drain for the AC and wrapped and insulated the full unit. I will be using these guys for all my AC needs going forward! read more

I Called them for a quote few months back. Gave me two options which was great so I knew what to save. I called and spoke to Rashad recently this month to see if they honor the same quote they did. Anna was keeping me up to date on my order and scheduled it the day I was able to be home for the service. They Came down to do measurements one last time after I agreed. With the proposal. They Came down yesterday changed out both furnace and ac units. They was truthful and honest up front when they quoted me , unlike other places , I'm glad I went with this company. Robert and steve was very polite and on time for the schedule appointment. Even gave me a walk through of everything that was changed out and showed me the damaged old unit. read more

Rashad and his homie are studs. Very transparent with pricing and potential issues. Let me know that he actually didn't recommend other areas of my AC to be serviced. He's pleasant to talk to as well. Definitely knows his stuff! I'm keeping his number handy. read more

I had to call about 12 other companies before I reached Rashad on a Sunday morning before a family party and our ac stopped working. He thankfully was able to stop by and was able to replace our ancient thermostat. Saved the day, thank you so much Rashad! read more

I was having issues with my AC and needed a new unit to be replaced. i went to 3 other companies, Omni Air gave us the best quote. On the day of installation, Abraham, Robert, Nathan showed up ready to work. They were very accommodating to my needs and were nothing but respectful. AC unit working great without any issues. Highly recommend Omni Air to anyone looking for a replacement or repair. read more

Dealing with these people has been a disaster. We paid $25,000 for a new HVAC system that barely does the job. Before purchasing, we were quite explicit about the areas of the house that needed more air flow. The air flow to these rooms is still insufficient. The owners have shown no interest in fixing the problem. It took over a month to even get one of them on the phone. Zach (one of the owners) finally came out to examine the system and his only proposed solution was to charge us thousands of more dollars for an addition mini split unit. The job they were paid to do still isn't done and they charged us another $100 just to come look at it. They've had to come back over 6 times because bad airflow is not even the only problem. Sometimes the unit just doesn't even turn on. They've worked on this issue several times and it still isn't fixed. Dealing with Omni Air has been a disaster from top to bottom. Save yourself a bunch of money, time, and grief by not purchasing their services. We had fewer issues with our 20 year old half broken AC unit that Omni Air replaced. Edit: In response to the comment from Anna F., this is not a maintenance problem. The filter has been replaced several times since installation. One of these times was by an Omni Air employee. Air flow is still insufficient with a brand new filter. I notice you have no response to the fact that the unit routinely fails to turn on. You can make things right by delivering the results you promised without trying to upsell us. read more

This company provides excellent customer service. We called at 11 am on a Saturday and they were here by noon to solve our problem. Amazing! Rashad the owner handled our situation in a very hands on and professional manner. As new home owners, we are thrilled to find a company to help us with our AC needs. Definitely recommend this company!!! read more

Do not use this contractor. Total scam. Omni diagnosis: bad induction pump, bad pressure switch, cracked mixing box. Cost to replace pump and switch over 1800. Could not replace box. Recommended replacing unit for $7,500. Found HVAC contractor who installed my AC 4 years ago. Checked unit. Pressure switch fine, mixing box fine, needed new induction pump. Installed new pump for $350. Omni said mixing box bad because of yellow in gas flame. My contractor said this was a favorite of scammers. Just need to clean jets. My heater is ten years old. My contractor said they usually last 15 years Checked Amazon. You can buy heater at retail for about $1900 plus installation. Contractor can buy at wholesale. No way you should pay $7500 for a new one. read more

Based on 5-star reviews on Yelp, I called a handful of HVAC companies to help me replace the 20-year old HVAC system at our rental property. Jakob shows up within two hours of my call, and he came with lots of knowledge, expertise, and good recommendations. He pointed out what needs to be done to help us comply with the latest building code requirements, he also answer all of my product and warranty related questions. Although my husband decided to purchase from another company due to brand preference, I think that Jakob's quote was the strongest of all the quotes we received. For those who are looking to buy any solid HVAC system or a system from one of the brands owned by Lennox, I'd suggest that they give Omni Air a call. read more

My A/C started to smell recently so I used Yelp's quote bot to contact A/C contractors. Omni was the first to reach out. The owner Rashad and Tim came out to diagnose the problem as "dirty sock syndrome" and gave me a few options to clean it and recommended to install an ionizer to prevent future problems down the line. I went with the most comprehensive package. I checked out another contractor which quoted me cheaper but ultimately decided on Omni. Tim, Richard, and Mustafa arrived on time and got straight to work: one cleaning the registers, another on the roof to clean the condenser, and third to clean out the evaporator coils, flush/fix the drainage line, and install the ionizer. The team was very professional and courteous. They worked quickly, cleaned up afterwards, and even looked at my dryer vents at no cost when I asked if they did dryer vent cleaning. They said the project would take 6 hours, they were out in 5. And most importantly, my A/C no longer has the horrible smell. Shout out to Rashad, Tim, Richard, and Mustafa on a job well done. I would give them 6 stars and will definitely use them for any future projects. read more

Couldn't be happier with these guys -- my elderly mom's HVAC had a bunch of issues and after reading reviews here I was confident that Omni would give her the personal attention needed. They totally delivered -- Jacob was extremely kind, patient and knowledgeable. He called me right after the diagnostic to explain what was wrong with the system and I found him to be trustworthy and communicative, so we proceeded with Jacob's repair recommendations. The needed parts arrived very quickly and Jacob completed the repairs right away and everything now works great! I am glad that Yelp helped me find this great company to help my mom...and so I want to be sure that others can benefit by using them too! read more

Needed an emergency diagnosis and repair for a non-working central AC unit. Fast response and arrived at the home within 15 mins. Diagnosed the problem within 10 mins and although it was an easy fix would not have known the issue without their expertise. Reasonable charge for the quick response and resolution. All of this done over phone and FaceTime since I was out of state! read more
