He left the pipe to show how much gunk came out of the system.
Angelica L.

I had a fantastic experience with Thomson Air. I needed a repair on my system, because it was turning on and off during literally the hottest week of the year. We inherited our system from the last homeowner, so we really had no idea what the issue was or how to go about fixing it. I had 2 other companies try to check out the problem, and 1 tried to re-do my whole HVAC system for 15k, and another never arrived when I scheduled an appt. Thomson felt like our last hope, and the technician Tom showed up, found the problem immediately, and fixed the issue in less than 15 minutes. It was just a simple clogged pipe that he needed to clean out. He also gave me a quick lesson as to how to prevent the issue in the future. It's hard to find honest people who want to actually fix a problem vs sell you something you didn't ask for. I'm happy I came across them, and the issue has finally been resolved!

How they missed the bright blue painters tape the first time, we will never know.

Now, full disclosure, been using thomson for 3 years now and I have to say, the people are great. Professional and polite. They are pricey but I was ok with that because they've been doing a good job and I was happy with their level of services. I have introduced this company to 3 of my friends and family. I will be sharing this review with them as well. That being said, I recently purchased a new home and despite the company my agent recommended, I decided to hire thomson to do a close inspection on the hvac system. WHAT A BIG MISTAKE. I made the inspection a week out and since we had to coordinate with the seller, I called 3 times throughout the week to confirm the time, EMPHASIZED that I was purchasing a new home and that this inspection was crucial to me. I also emphasize that thomson had to make it during the time frame as the seller was going to be leaving the house. I trusted them because they've been on time every other appointment. Needless to say, they were late. On top of that, they sent a newly trained employee for inspection. Now, I do not believe just because you're new, doesn't mean you're not qualified but that being said, I specifically requested someone more experienced. Regardless of what I said, there they were, the new employee to quote me for what is a huge purchase. Oh and due to the late arrival, the seller, of course, came back home. Embarrassing and unprofessional. Once the inspection was completed, there were some confusions around the quotation. I spoke to the technician twice and then the service manager once who all confirmed that the quotation was THE ONLY thing I needed. So the quotation was submitted for negotiation. Now, the house has been closed, done deal, I hired thomson to come perform all the services that was quoted and I found out on the day of the service that my duct work is falling apart. They initially insisted that the duct work happened to start falling apart after the inspection in which I had to go back to the original inspection report and found all the pictures. Then they said they were going to be providing a "competitive quote" where they literally quoted me more than double of what my "final quotation". Then to add the cherry on top, they were going to give me $500 off for my "inconvenience". This is all going to be costing me out of pocket now but do they care? Nope. Because Im just one customer and what was important to me was not important to them. They just provide a service and they do not own up to their mistakes. I found someone to fix everything for half the price by another company in half a day. Don't waste your money, go with someone else.

We had a great experience with Thomson AC. Brandon came out to do the estimate and gave us a very thorough quote that showed how thorough and knowledgeable they were. Flexible alternatives for payment, and not at all pushy or steering us toward more expensive options. The price was very reasonable overall. When it came time to do the actual install, James and Fayco were the main two installers and worked in parallel on the inside and outside portions. They laid our protective tarps to reduce the mess and protect the floors. They kept us updated as they were progressing and gave us a run through after showing us what to look out for. We were fortunate that their office/shop was close to our home as whoever a part didn't fit or they needed extra hardware, they put a call in and 10 minutes later another Thomson AC employee came by with the part that was needed. They tested the system for us, made sure it met specs, and were very efficient in doing the work. They stated a bit before 8am and finished about 3:30pm or so. This was for a Bosch heat pump and ADP air handler. The work is nearly done and everything very professional looking. This was our second time using them. Both great experiences!

Fixed the safety switch and gas pipe
Helen D.

I had a broken switch in my furnace that needed to be fixed for home warranty. The insurance contractor they sent out was horrible and condescending that I didnt want to work with them. So I had come to Yelp to find someone to help with our problem. Sent out a a bunch of requests but thankfully found Thomson AC. Josh was so fast to respond to me and super polite and patient with understanding my issue to truly help resolve my problem. He was also very transparent with me that they have a $90 inspect fee but if you do proceed with them, the $90 goes towards the repair cost. They were able to schedule me within the week and fixed my issue day they came out to inspect. Tom was super courteous and knowledgeable when he stopped by. He explained the issue I had and also warned me of a more dangerous issue I should be aware of. I asked him how much the repair would cost and having both done ended up being cheaper than the original quoted estimate! It was an easy decision to get both done. Tom was very fast to pick up the parts and resolve the broken switch and the other issue. The job was easily completed within 2-3 hours. I would definitely reach back out to Thomson AC if I have any other issues in the future with HVAC/furnace. They did a superb job for me and I hope for the folks reading this review, it helps you with going with them. Seems reasonable with how many reviews and highly rated they are. Can't go wrong with them!

In the two years since the installation, we've needed a few airflow adjustments, and each time the process has been easy-scheduling is smooth, and the work is handled efficiently and without any hassle. It's refreshing that their crew is alway, literally always, happy to answer questions, explain things, etc.

Multiple quotes, comparing equipment, warranties, pricing, all of it. At the end of that entire process 1st Choice was not just the best value we found, they were the best overall experience by a long shot. James the owner was involved from day one and that made all the difference. He was honest, straightforward and actually cared about getting us the right solution for our home. Not just the most expensive option or the quickest sale. The right one. That kind of integrity is honestly hard to find. The installation crew was excellent. Professional, efficient, clean and clearly very skilled at what they do. It was a complex job and they executed it flawlessly. They treated our home with respect throughout the entire process. We had a comfort problem in our home that had been going on for years and no one had ever properly addressed it. 1st Choice figured it out immediately, proposed the right fix and delivered exactly what they said they would. That problem is completely gone now. Every single interaction from the first call to the final walkthrough reminded me of what great service is supposed to look like. Responsive, honest, fair and genuinely excellent at their craft. If you are in South OC and need any HVAC work done these are your people. I cannot recommend them enough.

Kirk was FANTASTIC! Our unit is 20 years old, we have never really had regular maintenance on it. He showed up super early (they asked if that was okay, and YES thank you). Before he arrived they sent a text with his name and photo. I absolutely love this! That extra safety is so important. Kirk looked at our unit and asked some questions. He explained all they do with the "family plan" so we signed up. I am one of those that needs to be reminded of scheduled upkeep so this is perfect. He gave us the estimate before he started and I asked for a very rough estimate of a new unit (having no idea) so we decided to go with repair and hope for the best. The repair wasn't cheap but considering all the work that needed to be done as well as it being an older unit, I feel it was a very fair price. I think we did have the best with Kirk. He was able to repair our unit and give it some much needed TLC for our AC unit and furnace. He even installed our pre-purchased thermostat! Kirk was polite and considerate. He took time to answer all of our questions and ensured us that we could reach out with any questions, I believe him. Service people can often be rushed, there is a lot of work out there, but not Kirk. He didn't waste time either, I felt like he was in and out in no time at all. By the time he left we understood all that was done and what we need to do to get some additional service from our current unit. I could not be happier with the call I made this morning. I picked the right people to call!

They sent another company, I didn't get any "pre-paid" service but was quoted $3,300+ to fix it. I was graciously offered a short term fix for $1,000+ and charged $89.00 for coming out.
