Why Flex Fit™?

Flex Fit™ = Complete Climate Control for your Classic

The Flex Fit air conditioning kit updates your 1970 Pontiac Grand Prix with a complete climate control system including:

       • Powerful Air Conditioning      • Heat on the Floor      • Dehumidified Defrost

There are many reasons why Flex Fit is a great choice for your 1970 Pontiac Grand Prix. Click on any of the reasons below to learn more.

Not Just Aftermarket Air Conditioning [more]

Classic Auto Air's Flex Fit™ model-specific systems are not your typical, one-size-fits-all, low-quality, aftermarket air conditioning system. Every component was chosen for its superior design and quality rather than a low cost. Our RETROFIT designs give OE quality combined with better than original performance and reliability.

Components Selected to Fit [more]

Flex Fit™ system components have been specifically selected to fit an original, unmodified 1962 Pontiac Grand Prix. We even offer separate "heat only" and "factory air" versions. Please note: IF YOUR CLASSIC HAS BEEN MODIFIED IN ANY WAY, ADJUSTMENTS TO COMPONENT CHOICES OR MOUNTING MAY BE REQUIRED. PLEASE DISCUSS WITH YOUR SALES REPRESENTATIVE.

Electronic [more]

The Flex Fit™ system is fully electronic. No cables, micro-switches or vacuum pots to deal with. It gives you infinite control over air displacement and temperature.

Large, Separate Coils [more]

Size matters and ours are bigger! Larger AC coils provide more cooling power than small ones. This system contains AC coils big enough to cool the full passenger compartment of your 1962 Pontiac Grand Prix. In addition, it contains a large, separate heat coil, just like factory original systems, not the combined AC/Heat coils often found on an aftermarket system. (Our competitors combined coils save them $ but reduce system heating and cooling effectiveness). The theory behind our large air conditioning coils - click for more details.

Why AC Coil Size Matters?

Car air conditioning is nothing more than continuous heat transfer by two heat exchangers. One heat exchanger, the Evaporator, absorbs heat from the passenger compartment. The other heat exchanger, the Condenser, dissipates that heat into the outside air. All other things being equal, size matters. A larger Evaporator and a larger Condenser exchange more heat than smaller ones and allow the air conditioning system to cool better.

Factory Controls [more]

Flex Fit™ air conditioners are designed to use your original factory controls so your dash can retain that classic original look. Don't want to use your factory controls? We offer modern, replacement controls as well.

Easy Install [more]

Installation's a breeze! Our EZ Wire™ color coding system makes wiring connections a snap. Just match the colors.

Our EZ Cable Integrators™ simplify the attachment to your control head. Our Flex Fit™ systems are not designed to bolt-in as our Perfect Fit™ system.

Fully Customizable [more]

Use the factory controls or not, use the factory vents or not, run the ducts, lines, and hoses as you choose. Side, rather than rear, hose connections let you customize the hose layout for a smooth firewall or as you otherwise want.

Fully Serviceable [more]

The Evaporator Unit in this system is fully serviceable in the field. No glued housing like our competitors that makes field repairs impossible.

Customer Service and DEEP Product Knowledge [more]

Most of our customers are referred by other satisfied customers. Consistently among the top reasons customers give for buying from us is our customer service and product knowledge.
