First Response Air Conditioning & Heating Inc. is really top-tier. Their entire team is wonderful, reliable, and genuinely committed to taking care of their customers. Ivan is extremely professional, trustworthy, and an absolute expert in his field. He gave me honest guidance and made the whole process stress-free. Brandon came out to calibrate my furnace, and now it's running like brand new. He took his time, explained everything clearly, and delivered outstanding customer service from start to finish. His professionalism and deep knowledge really stood out, and you can tell he takes pride in doing things the right way. The level of care, honesty, and craftsmanship this company provides is rare to find. If you're looking for a dependable team to maintain or repair your HVAC system, look no further. These guys are the real deal, and I highly recommend them to anyone who wants quality work and true peace of mind. read more

These guys are good. My AC quit in the middle of heat wave last week. Called First Response in panic. They tried to fit me in. Ivan came at 7:30pm exhausted, but in full spirit. When I explained the symtoms, he immediately knew what was wrong. Replaced the defective part, my AC was up and running. No-nonsense guys. I strongly recommend the First Response guys. read more

We called First Response AC/Heating when our furnace stopped working. Brandon was at our house in 2 hours. He very systematically checked all possible causes, thermostat, circuit breaker, as well as everything in the furnace. He found a deteriorating door switch which he bypassed, restoring heat. He did not try to sell us something we didn't need. He was very pleasant, competent, knowledgeable, and patiently answered all our questions. We will definitely use this company again and can recommend them without reservation. Mike/Darlene read more

Honest, reasonable pricing, punctual, and more than anything, they are experts in both heating and air conditioning. I have used Ivan and Brandon at least 4 times and they always amaze me! I highly recommend! read more

I would give 0 stars if that were an option. Brandon came out during an extreme heat wave in which caused our AC to go out. My husband had a feeling of what may have caused it but unfortunately was out of town on business when this happened so he couldn't check it. I along with my 2 young children were desperate so my husband called First Response to come out and diagnose our problem. Brandon came and seemed very friendly and honest however evil has many faces. He showed up and checked our unit and gave us 3 options: 1 - fixing the compressor for $9,700, 2 - new unit $12,000, option 3 - new unit $14,000. The stress this caused on my husband and I was absolutely overwhelming! Obviously desperate with 2 small children in a home which was up to 90 degrees at this point we stressed about how we would come up with such money. The stress about this was so overwhelming I decided to reach out to an old family friend (who works in commercial AC and which I felt bad to do but again - I was desperate). He was so kind and said he didn't trust that we needed a new unit and volunteered to come check it out the following day. THANK GOD! That night I spent $550 on a portable AC unit which I had to figure out how to install on my own just to make the house livable. The temps outside reached 102. The following day the old family friend came and diagnosed the problem in 2 minutes and it ended up being THE MOST COMMON PROBLEM in AC units. The capacitor. The FIRST thing they train AC techs on. The MOST LIKELY to go out in a heat wave! He stressed how much this is happening in the residential AC sector and how more people need to expose these companies for fraud, and how it's making all AC companies look bad! ... So this company tried to sell us on a new AC unit when all we needed was a $30 part!!!! I can't stress this enough .. this company is CORRUPT! They will take advantage of you! Avoid at all costs!! We reached out to Ivan the owner in hopes he would do the right thing and at least refund our diagnosis fee of $85 and they will not respond to our calls/texts. Clearly can't even do the right thing when they know they are in the wrong. Currently disputing the charge with our bank. read more

When there's a heat wave, the last thing you want to hear from your spouse is "our A/C stopped working!" Especially in a two-story house that heats up quickly, it can get pretty uncomfortable. Eager to find someone who could come on the same day, we called around and landed on First Response Air Conditioning. They said then could send someone same day but it would be sometime between 4-6p, which worked perfectly for us. There is an $85 diagnostic fee, but if you remember to mention (I didn't unfortunately!), they have a coupon on their website that waives that fee for your first time using them. I got a text and phone call from the technician, Jody R., who let us know he was en route. He showed up and immediately jumped in to diagnose the situation. He was friendly, explained clearly to my husband what our potential issues may be, and then jumped in to identify the problem (it was our compressor!). He fixed it quickly and efficiently and within no time, we were feeling the cool breezes from fully functioning A/C. Thank you First Response and especially to Jody - highly recommend their services! read more

Great service . They came fast and fixed my unit in the summer heat wave we had a home warranty but decided we trust first response to be honesty read more

Ivan and his team did a great job. They are very knowledgeable and efficient. Price was also reasonable. I am very happy the work. I highly recommend them. read more

Nothing but a positive experience with First Response. I had a busted AC unit amidst the crazy heatwave and First Response was the first company to call me back. Ivan arrived a few hours later and within minutes diagnosed the issue. He immediately drew up the cost of the part and no hidden fees or what not. Thankfully, he had the part on him and got us up and running within 20 minutes. It was a hot week and I overheard him talking to another customer and making time to see them. So appreciate his efforts and skills. This is a local and family operated business, I'm all for supporting our community and Ivan did not disappoint. Highly recommend their services!! read more

They responded quickly and replaced my air conditioning unit on one of the hottest days of the summer in one day. Brandon was amazing as well as the other technicians who contributed to the horrible situation on a 97° heat day. Nothing but praises for these guys. read more

This is a family-owned and operated company that stands behind their name. They are professional, courteous, knowledgeable, cost effective and deliver "World Class Service". They truly care about their customers so do not bother with anyone else as they pale in comparison. I purchased a home a few years ago with a hard to diagnose heating issue on a heat pump system. Had 3 different HVAC companies come out and each one replaced multiple components without solving the problem. Then I called First Response Air Conditioning & Heating. Brandon came out and worked hard to find the problem. He went the extra mile by calling the manufacturer for some much-needed technical help which led him to the root cause of the problem. He then fixed it and worked flawlessly for years. Just called Brandon out again because a part one of the other companies replaced failed. Brandon and his dad Ivan found the replacement part right away and their team replaced it the next day. This is how it is done folks. read more

Called First Response Air regarding my T-Stat from the initial contact customer service was upmost! I was able to speak to Technician within an hour of my request! Brandon explain of possible issues that could be causing trouble, which honestly I didn't expect this type of quick response being that it's very hot, I expected them to be extremely busy, set up appointment for next day Brandon was timely, as soon as he saw my T-Stat he assessed problem and fixed it, I then asked for system tune up which he did! AC system is great! After speaking with Brandon he mentioned that First Response is a family run business based here in Yorba Linda, it's great to have businesses like this in our city! If you are in need of an AC tune up give these hard working folks a try!! read more

Within 24 hours I had my system diagnosed and a new outside ac unit installed and cooling my home. Service was prompt, courteous, fair, honest, respectful and reasonable!! No surprises. So grateful for this awesome business! read more

I really appreciate First Response. I had an issue with having to relocate my thermostat and with no hesitation was able to come out the same-day and explain in detail what it took how far they can go out and a quote .So thank you Ivan. Matt was able to come over and get it done within the hour Very professional and would highly recommend this company. read more

I had a great experience with these guys. They were up front with pricing and did a great job with my HVAC. Highly recommended

If I could, I would give them 10 stars. Our AC went out last night and by 10am it was miserably hot in our house today. I called First Response and at 1pm our AC was fixed. Ivan squeezed us in on this extremely busy holiday weekend and sent a technician right out. I haven't had an experience like this with a company for as long as I can remember. I would recommend First Response to anyone. Thank you so much Ivan and team, this weekend would've have been horrible if you didn't go above and beyond. read more

I put in the request in the evening and had Ivan gave me an appointment for the next day. Brandon arrived and diagnosed the problem with the capacitor (which he replaced) and the electric motor which he had to obtain. Ivan came back out the next day with a generic electric motor (the OEM was backordered) which required some rewiring to install. A very knowledgable team including Jody; did a quick, clean job, highly recommend. read more

Never fixed the problem. They just left without fixing and decided lunch was more important.

Love the service, fast response and knowledgeable. Highly recommended, price was right.

First Response was VERY quick to respond and came out the very next morning after I texted them. Matt was on schedule and very friendly and quick. He brought shoe covers/booties as to not dirty my floors. My only complaint is regarding what I paid (please take this with a grain of salt as I realize labor these days is quite expensive): 1. As someone who knows nothing about ac units and most handy work in general, I did not know I had to change out my filter (that's my own mistake). I thought I had a much bigger issue which was causing a leak from the emergency line (pipe), but turns out it was just because I needed to change out my filter. That cost me $295. He did say he would take 30 minutes to blast/clean my lines with nitrogen, but it only took 5 minutes because there wasn't an issue at all with my lines, they were working fine and were doing what they were supposed to be doing. Still cost me $295. 2. He told me he would "throw in" changing my filter and cleaning my coils in that $295 fee. However, bc I did not have a hose spout at the front of my condo where my AC unit was, he was unable to clean my coils, and therefore decided to knock $40 off. So my total was $255 to change my filter and clean my line for 5 minutes. 3. When they initially called me, they told me it would be $65 just for the diagnosis and visit which I agreed to. So that means it cost me $190 to change my filter and to "clean my lines." Now when I asked him how bad were the lines, he said they weren't clogged or bad. When I asked if I even needed them cleaned, he gave me a mix of answers. At one point he said yes, and another point he said not really because the issue was my filter. When I stated "oh gosh I feel like I basically am paying $295 to just have my filter changed," he just shrugged his shoulders, which indicates to me he knows deep down inside that I am paying WAY too much (which is also why I think he knocked $40 off because he couldn't clean my coils). I totally understand that these repairmen work on an hourly basis and they had to make the trip to my house and assess the situation and get paid but at the end of the day I wish they were a bit more fair with the price, than what I feel like was taking advantage of a girl who doesn't really know any better than pay $255 for her filter to be changed. I'm still giving them 4 stars because they were punctual and did the work. read more

They sure did respond very quickly to when I called and asked if they could come look at my AC that had just stopped working. They came next day (not same day bc I called at 6pm) and found the issue right away. They worked with my warranty on the system to get the part free of cost, and were very fair on the labor charges. They showed me some other things I also needed to get done to make sure my system would be on top shape! If I had any constructive feedback is that sometimes they'd say "I'll follow up by X, and wouldn't get back to me" so I did have to do a bit of chasing. But it didn't bother me too much bc they were very nice and willing to help. Would call them again for sure and do recommend them! Really felt like I could trust their expertise! read more

It's been a long time since I've trusted a business. First Response will EARN your trust. I wish other businesses would follow their model. Super courteous and when they're done, you will have a thorough understanding of you air or heating unit. You will know exactly what you are paying for and why. They go the extra mile cleaning the unit and adding additional precautions at no extra cost. Nick and Mike worked on my unit today and were super professional and clean. If you're weary trusting today's businesses, you can relax with these guys read more

Ivan and his team were awesome. Was real honest with what we needed to get done and saved us some money along the way. The other company I used before would have just fixed it and not care if I have to fix it again. Thanks to this team we have our new go to guys to get our air fixed!! Really happy with them. Update 12/17/2018 Came to our house today to do maintenance on our system. Really happy with their team of people. Always friendly and respectful. Definitely recommend to anyone needs their system fixed or maintained. read more

On time, great knowledge, diagnosed and fixed my furnace fast. I highly give my recommendation read more

My A/C broke down in the middle of the heat wave a few weeks back and the big name companies wouldn't show up for at least 4-5 days so I reached out to First Response on a Sunday night, they called me right back and were at my house first thing Monday morning. Ivan was very knowledgeable and figured out the problem right away. He had us back in business in no time. read more

I called First Response this morning and was schedule same day for 11-1230 window. Brandon arrived within that window and troubleshooted my unit and did a service check. Turns out the capacitor was going bad and he replaced. Service was good, timing was perfect and very professional. They also notify you via text when the technician is en-route, plus the invoice is emailed to you after the service is completed. Give them a shot the next time you need AC service. read more

Ivan & Jodie we're god-sends on a Sunday evening, after hours, and during the Labor Day holiday weekend no less! Ivan diagnosed the problem with our condenser within seconds of walking in the house. He was extremely knowledgeable, professional and friendly. He had the replacement part on-hand and the repair was completed in just a few minutes. If you are having issues and need help, don't hesitate or bother researching any further, just call First Response! read more

Our AC went out a couple days ago in the busiest time of the year for these guys and they were able to send me a technician next day when everyone was scheduling for a week out. Mind you we have a baby... Ivan came out and even touched base about being late(well appreciated). He was able to fix our problem in under 20min and got out of the way for us to enjoy the rest of the day. Great work ethic. Honest and straightforward. No BS up-sell or trickery. Definitely worthy of a future call. read more

I burnt the board on my furnace and the contactor on my AC unit. I couldn't get anyone out until next Monday and it's 100 degrees today. Luckily Ivan came to the rescue in less than an hour. He was super friendly and knowledgeable. He showed and explained everything he did. He also gave me a discount. I highly recommend him. read more

Sometimes, buying Major Appliances is kinda like buying a Car, and your experience is only as good as your "Salesman". I was about to go with another popular Company in the area when they turned "Car Salesman" on me. I called 1st Response to get another bid and Ivan came and scoped out the job. He was professional and straightforward and he had my deposit check in 30 minutes. The installation was on time with no "line item mystery charges" and finished in a little over 1/2 the time promised. I'm actually happy the other company "slimmed out" because there's no question who my HVAC Company is going forward. read more

Judy booked us into the first slot available during the heat wave for an inoperable air conditioner. She was very kind and even called to get us in a day earlier due to a cancellation. Matt arrived on time, was very knowledgable and fixed the problem with a bad capacitor in minutes. We now have cool air and are very comfortable. Very reasonable prices, great service from all across the board. Highly recommended! read more

Shows up in a mask, comes on time, finds the problem in minutes and fixes in minutes. Glad I called them and Ivan got the job done. Surviving the heat wave. Loved especially how soon I was able to get an appointment in with these guys. read more

Trustworthy, fast, lifesavers. Ivan and his team came out so fast and helped us before the hottest weekend of the summer. I can't thank them enough for coming on such short notice and making this happen! I will forever be thankful for them! read more

Great job Matt showed up only two days after I reported the problem whereas other companies could only come 5 to 12 days later, which was greatly appreciated considering the heat wave that we were having. He fixed the problem quickly and professionally. As a bonus, he even replaced the air filter on the ceiling, which was hard for me to reach. He also used American made parts, which will hopefully last longer than the cheap Chinese part used by another company last year, which blew and caused the AC to fail. read more

I can always count on First Response!! We purchased our AC from them 3 years ago, Saturday evening of Labor Day weekend and my AC goes out ‍ I call and Ivan answers and is professional and pleasant on the phone, assures me they can fit me in for Sunday. On Sunday Ivan showed up on time and was just as pleasant in person, he wore a mask at all times and respected our home. Thankfully it was just blown fuses, Ivan replaced them then gave me a discount on the cost!!! Thank you First Response, Thank you Ivan!!!!! read more

First Response Air Conditioning and Heating lived up to their name and standard! I called to have someone come check my AC unit which had stopped working, and they responded with a home inspection and repair within one hour. Yes, one hour!!! We are impressed with their prompt response to our request given that all other companies had given us a one week timeframe. The repair was done within minutes and the cost affordable. We can now sleep comfortably especially during the weekend heat wave in OC. Thank you First Response!!!! ~James and Sagui Doering~ read more

My AC unit broke and Ivan came out the same day I called. He diagnosed the issue and helped me understand what was wrong. Then two days later came and replaced my unit. Great customer service and speed of service. Would recommend them to anyone! Super happy with my experience with first response. read more

Ivan and son are amazing. We have no problems with our new A/C. Thank you for a great job.

Ivan and his team were able to fix my AC unit when two other companies couldn't figure it out. It was a quick fix after Ivan went down the list to figure out what the actual AC issue actual was. read more

Called First Response on a Saturday morning when our 20 year old condenser crapped out. Ivan - the owner - was at my house within an hour and immediately gave me multiple options. Having dealt with prior HVAC contractors, I was pleasantly surprised by how reasonable the quotes were. There were able to install a completely new system - HVAC and all - within 6 hours. Immediately recommended them to several friends and family. read more
