A simple, no-jargon explanation for Arlington & DFW homeowners. Why your AC blows cold air — and what can go wrong in Texas heat.
A simple, no-jargon explanation for Arlington & DFW homeowners. Why your AC blows cold air — and what can go wrong in Texas heat.
Your air conditioner doesn’t “create” cold air — it moves heat out of your home.
Here’s exactly how it works in plain English.
Located in the outdoor unit. Compresses refrigerant gas, raising its temperature and pressure (like squeezing a balloon).
Outdoor coils release the heat into the Texas air. The hot refrigerant turns back into a liquid.
Lowers pressure so the refrigerant gets very cold — ready to absorb heat inside your home.
Inside your air handler or furnace. Cold coils absorb heat from your indoor air — blowing ice-cold air through the vents.
Result: Your home stays comfortable even when it’s 105°F outside.
High humidity + extreme heat make your AC work harder than almost anywhere else in the country. That’s why regular maintenance (coil cleaning, refrigerant checks, capacitor testing) is essential to keep it running efficiently.
It moves heat. Cold air is the result of heat being removed from your indoor air.
12–15 years with proper maintenance. Many last 18+ years in DFW when serviced yearly.
Seasonal Energy Efficiency Ratio. Higher SEER = lower energy bills. We recommend 16+ SEER for new installs in Texas.
No — it’s illegal without EPA certification and usually means there’s a leak that needs repair first.
