Did you know there is a right way & wrong way to install your air filter? 🤯👇

It seems like a tiny detail, but that little arrow printed on the side of your HVAC filter is an important details that sometimes get's missed. It shows the exact direction the air should be passing through the filter. The filter was engineered with additional structural reinforcement to withstand the force of the air pushing against it.. When you flip it the wrong way, it's not the end of the world but there is the potential of the filter not catching as much dirt as it should, which can lead to damage to internal components, or it could be pulled into the blower wheel and cause more damage.

How to check yours right now: 1️⃣ If your filter is next to your furnace: Point the arrow toward the furnace unit. 2️⃣ If it’s in a ceiling or wall return grille: Point the arrow into the wall/duct.

It only takes a few seconds to verify, but it can prevent unnecessary damage, extending the life of your AC and keep your home much more comfortable this summer!

👉 Want total peace of mind that your system is running at peak efficiency? In addition to simple things you can do yourself, like replacing your filter, manufactures recommend you have your air conditioner inspected once a year by a trained professional. Our AC tune-up is based on the manufacture's recommended maintenance and inspection items. Call +1 760-798-3665 or schedule online (link in bio) today

Think of your outdoor AC unit like a giant, breathing filter for your home. 😷👇

Every single day, your air conditioner sucks in thousands of cubic feet of air to keep you cool. But along with that air, it’s also trapping cottonwood, lawn clippings, dust, dirt, and bugs. When that "filter" gets completely choked up with debris, two things happen:

1️⃣ Your system has to work twice as hard to pull in air (hello, spiking energy bills).
2️⃣ It puts massive strain on the compressor, which can lead to a sudden breakdown right when the summer heat hits.

A quick rinse with a garden hose can do wonders, but a professional coil cleaning clears out the deep-down grime that restricts airflow. When was the last time your outdoor unit got a good wash?
