Worst I’ve seen in 34 years!

I’ve never seen a capacitor blow up and cause all the wires to melt together like this before… and I’ve seen hundreds of blown caps over the years! I even had to fix the wires inside the unit to the compressor, crank case heater, both High and Low Pressure switches… even had to replace 24V t-stat wire that was all melted together about 18”-24” away from the unit!! 😳

Well, we’re 1/2 way through August now, but after an actually pretty mild summer McGarrett AC is finally all caught up and able to offer same day service again (in most cases). So if you’re noticing that your AC isn’t acting like it should or you just want a check up to make sure things stay a...

You know that August has arrived when it’s 10 o’clock on a Friday night and you’re still out running calls with 2 more to go… And the last 2 are willing to wait as long (or as late) as it takes for us to get out there!!!

Here’s a few pics from the install we did yesterday… We have a few “Before” pictures mixed in with the “After” so you can see the difference.

In addition to it just being a SUPER clean install, we have pics of the new “Return Air Plenum” that we added (last system just had holes cut into furnace 🤦‍♂️), a new “In-Line Filter Cabinet” for 20x25x4” R/A filters, a new safety drain pan with a new “Aqua Guard Safety Float Switch”, a new “PVC Ball Valve” with a riser for pouring bleach and cleaning drain-line out (this is to isolate the coil allowing for an easier and more efficient way to clean the primary drain line).

We’ve also added in a new “Reme Halo” air purifier for her in her supply air (the same one I have in MY house and love) and we put in all new “Start Collars-With Dampers” in every S/A duct (for balancing airflow and giving her total air control) attached to the new R8-Insulated “Supply Air Plenum” that we installed on the system to top it all off!! 👍😁

On the outside, we installed a new “3.5 Ton 454B RUUD Condensing Unit” after thoroughly flushing out the copper line set with RX-Line Flush. This is to remove any R22 contaminants left in there from the previous system. We put in a new 16 in.³ Liquid Line Dryer, pulled the system into a deep vacuum for over an hour and opened up the “King-Valves” introducing the new 454B Freon into system. We then dialed the charge in to the manufacturers spec’s and her new system is back up and running, back blowing and cooling better than ever!!

Happy 4th of July Everyone!!
🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸

Some really helpful advice for you all… If you can find any free time over the long holiday weekend, take a few minutes and pull your water hose over to your condensing unit outside, wash out all that dirt from inside of your coil (You can find some How Too videos on our page if you have any questions). Keeping that coil clean outside will give you better comfort inside! It will also giving you cheeper light bills and will reduce the strain on the unit allowing it to live a longer life (and that ac units NOT cheep). Trust me, it’s well worth the time and effort!!👍
Have A Great Weekend!

*If you ever have any questions about anything, you can always call on us! We’re always happy to help!

We will be open July 4th for all your emergency calls! 🫡 🇺🇸

✨ Happy July Everyone!! ✨

It’s only the 1st day of July guys, but we’re going to be starting the month off with our first heat wave of the year!

Homeowners, our AC Systems WILL be put to the test this week for the first time in 2025. With temperatures expected to be above normal all week and as high as 98° for the next 5+ days, it’s going to put a strain on those AC systems! 🥵

Please, let McGarrett AC help you help yourselves… When you get time TODAY, go check out our videos on how to wash your condensing coils. Keeping those coils clean is something that’s so simple to do, but it has such a drastic positive effect on your AC systems!!

Comfort, lower light bills, less strain on your equipment so that it may last you longer… all from keeping your coils clean!!

STAY SAFE OUT THERE!!
Never stay in a hot house for long, escape to the grocery store, friend’s house, or even just sit in your car until help arrives!

** Remember to check on your elderly and either bring in your pets or make sure they have LOTS of water!!

Here’s a few pictures of installs from 2025 that i remembered to get - I just wish I had all the before pics to go with them.

Our guys are some of the best when it comes to quality and attention to detail 👍

*Some of the best pictures I have to offer are the ones I never took! Those are the ones that we were able to FIX the AC and KEEP RUNNING for another year (or longer 🤞)!! Our goal is to always fix 1st and only replace as a last option!👍
