Why Your Air Conditioning Needs Regassing Even in Winter

Many drivers associate air conditioning solely with hot summer days, assuming the system does not need attention during the colder months. In reality, your air conditioning system is just as important in winter as it is in summer. Leaving your AC turned off all winter can cause system leaks and compressor failures. Here is why you should service your air conditioning year-round.

Clear Windscreens & Rapid Demisting

Air conditioning systems do not just cool the air; they remove moisture from the cabin air. When you turn on your car's demister on a damp winter morning in Paisley, the AC compressor runs to remove humidity. This dry, warm air clears condensation and defogs your windscreen much faster than normal heaters. Running the AC in winter is essential for clear visibility and safe driving.

Preventing Seal Dry-Out and Leaks

The refrigerant gas in your AC system contains a specialized lubricant that circulates through the system. This oil keeps the rubber seals and O-rings lubricated and flexible. If you leave your AC turned off all winter, the oil settles at the bottom of the system. The seals dry out, shrink, and begin to leak refrigerant gas. Running your AC for at least 10 minutes a week year-round keeps the seals lubricated, preventing gas leaks and expensive repairs.

Why You Need a Professional Regas

Air conditioning systems naturally lose about 10% of their gas per year through the hoses and seals. If your system is low on gas, the compressor has to work harder, increasing fuel consumption. Our AC service includes recovering the old gas, performing a vacuum leak test, refilling with fresh refrigerant (R134a or newer R1234yf), and adding fresh compressor oil to ensure optimum performance.

Anti-Bacterial Cabin Sanitization

Moisture inside the AC evaporator can lead to bacteria and mold growth, causing musty odors and triggering respiratory allergies. We offer anti-bacterial sanitization treatments to clean the air ducts and refresh your cabin. Visit K66 Motors on McGowan Street for a full AC service.
