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.
