Alex you are so awesome!

The tech that came out yesterday evening was absolutely amazing! He was knowledgeable, respectful, professional, and funny! Instead of saying hey this is what's wrong with your unit and you need this, this, and this, he explained how the AC was working and what went wrong. The previous company (1 hour air 🤮) that we got our gigantic $16,000 air conditioner through about 4 years ago, sold us the wrong unit! They sold us a roof unit for a house that has all the ducts under the damn house! So after spending money with Semper Fi and having them come clean and seal the ducts as well as replace that blower motor in the 1 hour air unit....Alex came out because we couldn't get the unit to shut off. Well long story short the motherboard got fried in the spot that turns the blower off and it was stuck on! Soooo back to Alex, he explained everything and as the second Semper Fi tech to come out to our house - he lasted through all my ridiculous questions and sarcasm! Alex is truly a wonderful guy, he loves what he does and you can really tell that he cares. We had a hiccup in the process of payment and he quickly solved that (also shout out to the guy that also helped me through that process over the phone). Alex stayed through the slightly stressful conversation I had with my mom trying to decide how we could afford a new air conditioner because let's be real spending $16,000 and still owing on the unit after only four years of owning it and then spending even more money to get a new unit is kind of ridiculous! I am very glad that we had Alex come out to diagnose the issue that we were having. He knew exactly what was wrong (very quickly I might add) and he gave us different ways on how it could be fixed. Of course the easy way would be putting a Band-Aid over it but that wasn't what I wanted to do! When I say this company truly is amazing I am not over exaggerating, I feel like even though it is very costly to buy a new air conditioner especially nowadays, Semper Fi made it a little bit easier and I am in love with the fact that all of our questions and then some were answered and explained. I really can't say more about this company besides they hire very good people and they do a really good job!
Please buy Alex a good lunch 😂 or give him something special! 😋 I know he works hard, along with all the guys I have interacted with from this company!
Thank you so much!

Very personable, makes sure everything is done the proper way and checks off everything that needs to be done. He’s solving a 3 year long issue for us where many many other service techs could not. Would highly highly recommend Colin.

We had our AC quoted and they were able to install next day. I followed up with it not quite cooling, and they came right away to adjust the fan speed to get more air flowing. Semper Fi is very quick in response, which is important to me.
