Another successful install for CSO Mechanical LLC today!

Our customer’s HVAC system needed replaced, and once we removed the old furnace, we discovered 6 cracks in the heat exchanger…. something that can become very dangerous and should never be ignored.

This is your reminder to have your gas furnace inspected yearly. Regular maintenance doesn’t just help your system run better, it helps keep your family safe.

We were thankful to get our customer back up and running with cold AC again just in time for the warmer weather ahead.

Thank you to everyone who continues to trust our small family business. We truly appreciate every call, referral, and customer!

Catch of the day 🐟🧊

Yes that monster block of ice Chris is holding came straight out of a commercial walk-in refrigerator that wasn't keeping temperature.

Here's what happened: ice had built up completely over the evaporator coil inside the unit. When that happens, air can't pass through the coil to get cooled so the fridge just keeps running without actually doing anything. Meanwhile, temperatures inside the unit creep up and food safety becomes a serious concern.

Chris pulled the ice, diagnosed the root cause, cleaned the coil, and got the unit back up and running.

If you own or manage a restaurant, grocery, or any business with a walk-in cooler or freezer and it hasn't been serviced recently this is your sign to get it checked out before something like this happens to you.

ONE MORE WEEK 💙
Our team at CSO Mechanical LLC is hiking for Hike for Hope to raise money for su***de awareness and we’re in the final stretch.

If you’ve been thinking about giving, now is the time. Every dollar helps, and no amount is too small.

Thank you to everyone who has supported, shared, and encouraged us. Let’s finish strong and continue spreading awareness every life matters.

We’re sharing something that’s really close to our hearts.

As CSO Mechanical, we’ve joined the Construction Hike for Hope to support su***de prevention…. and this isn’t just another fundraiser for us. All three of us personally know someone who has taken their life, and we’ve seen the kind of pain it leaves behind. It’s something no family or friend group should have to carry.

When we learned that su***de is the leading cause of death in the construction industry, people we work alongside every day, we knew we wanted to be part of doing something about it.

We’ll be hiking on Saturday May 9th and we’d love your support as we lead up to it.

Our team goal is $500, with each of us aiming to raise $150.

When you donate, you’ll choose one team member (Austin, Sam, or Chris) to give to or you can bless more than one or all three if you feel led. Every dollar goes toward our team total and supports the American Foundation for Su***de Prevention.

If you’re able, we’d truly appreciate your support… no amount is too small!

More than anything, we want to help spread awareness and remind people that their life has real value. They matter. They’re not alone.

Thank you for standing with us. ❤️
