Once upon a time, factory air conditioning was one of the most (if not THE most) expensive automotive options you could buy — rarely seen at all, and then mostly on high-end American cars like Cadillac or Lincoln. During the 1960s, however, the popularity of air conditioning really took off on U.S. cars — particularly on low-price full-size cars. Let’s take a look at how many big Chevrolets, Fords, and Plymouths had factory air conditioning during this period. Some of the results might surprise you.

As with my earlier posts on manual transmission installation rates and stripped-down full-size Chevrolets, this data comes from the annual statistical issues of Chilton’s trade journal Automotive Industries, which surveyed U.S. automakers to compile installation rates for different optional equipment. It includes only full-size models (except the 1959–1963 Chevrolet totals, which include the Corvette, but not the Corvair or Chevy II), not each brand as a whole.

In the 1959–1961 period, air conditioning installation rates were low overall (6.2 percent for 1959, rising to 6.9 percent for 1960 and 8.1 percent for 1961) — SO low that you’ll notice that I cut off the Y-axis as 50 percent to make the individual bars more visible. Not many buyers were willing or able to afford the $400+ price of factory air conditioning, especially on a low-price make where the option would have added 15 percent or more to the total cost of the car. Thus, the A/C installation rates for the “Low-Price Three” lagged a good bit behind the industry average.

The main surprise is that Ford buyers were more likely to order air than were buyers of full-size Chevrolet or Plymouth models; this was generally true of other options like radio and power steering as well. Although Ford had struck out hard with its attempts to expand its mid-price brands (Edsel was gone midway through 1960 and Mercury was on life support), they were doing quite well at getting customers to pay a little more for a Ford.

In the 1962–1964 period, you’ll notice something interesting: Through 1963, the air conditioning take rate for full-size Chevrolets lagged behind the overall industry average, but starting in 1964, it leaped ahead, reaching 17.7 percent, compared to an overall domestic average of 17.1 percent.

As I noted in my earlier post about stripped-down full-size Chevrolets, I think this shift was probably related to the introduction of the midsize Chevelle/Malibu line pushing the bigger cars upmarket, but the jump was even more dramatic than I thought. Full-size Chevy sales were down a bit for 1964 (by about 19,000 units), but Chevrolet sold about 80,000 more air-conditioned big cars than in 1963.

On a percentage basis, Plymouth air conditioning sales were up even more sharply for 1964, although because Plymouth buyers had been less likely to order air before that, Plymouth installation rates still lagged behind Ford and Chevrolet, and well below the industry average. Also, sales of bigger Plymouth models were still weak during this period.

Total Plymouth production (excluding the Valiant) was 244,395 in 1963 and 274,689 in 1964, meaning Chevrolet sold more full-size cars with A/C than Plymouth sold bigger cars.

From this point on, the A/C installation rates were high enough that I’ve extended the Y-axis of the charts back to 100 percent, so bear that in mind when comparing the charts.

The big surprise in the 1965–1967 period is that the air conditioning installation rate for big Plymouths, which had previously been significantly lower than full-size Chevrolets or Fords, suddenly jumped ahead for 1966, going from 20.4 to 32.1 percent in just one year.

Full-size Plymouth sales were fairly consistent in this period, but about 31,500 more of those cars were sold with air conditioning in 1966 than in the previous year. For 1967, the Plymouth A/C installation rate climbed to 45.2 percent, a figure more comparable to midprice brands like Pontiac (46.6 percent) or Mercury (50.0 percent).

Some of the growth in factory air conditioning installations was undoubtedly due to the introduction of the LTD, Caprice, and VIP. The installation data for these years isn’t broken out by series, but I don’t think it’s a stretch to surmise that the buyers of these mass-market luxury cars were more likely to order air. However, even that doesn’t fully explain the upswing at Plymouth. (The VIP wasn’t a big seller, selling around 18,000 units in 1966 and about 18,500 for 1967, and even if every one of those cars had air, it wouldn’t be enough to account for the increase in A/C sales.)

The A/C installation figures for 1968 and 1969 come with an asterisk: For 1968, Ford (and only Ford) broke out its full-size model optional equipment installation rates by trim series, lumped together as Custom (which I assume included Custom and Custom 500), Galaxie (probably including both the Galaxie 500 and Galaxie 500/XL), and LTD. I came up with a weighted average for the chart above, but this is a very tenuous estimate because it’s not clear which production figures were used for the denominator.

It’s too bad that this kind of breakout isn’t available for each of the three brands, but that’s the way the data was published. (For 1970–1971, full-size Plymouth installation rates were broken out by series, but Ford and Chevrolet were not.)

However, it seems likely that 1968–1969 trim series breakouts for the full-size Chevrolet and full-size Plymouths would show a similar pattern, with A/C more common in the Caprice and VIP than in the Biscayne or Fury I. While the pricier models still didn’t predominate in total sales volume, they undoubtedly pushed upwards the overall installation rates of extra-cost options like air conditioning.

Comparing the beginning and end of the decade, it’s obvious that the overall popularity of air conditioning on U.S. cars had increased dramatically. This was largely a function of economics: Although automotive air conditioning was still expensive, it was a bit more affordable in 1969 than it had been 10 years earlier, both on an inflation-adjusted basis and as a percentage of vehicle base price. More significantly, median family income in the U.S. had increased from $5,400 to $9,400 per year between 1959 and 1969. Calculating how much real gain that increase represented in purchasing power is more complicated (MeasuringWorth offers several estimates of how much the 1959 figure represented in 1969 dollars), but overall, Americans in the late ’60s had substantially more money to spend than U.S. households of previous decades.

The United States Census Bureau put it like this back in 1970:

The increase in family income for 1969 is a continuation of the general trend in rising family income during the past 22 years. Between 1947 and 1969, median family income in current dollars has tripled, rising from about $3,000 to $9,400. Although some of this increase was eroded by rising prices, the rise in real purchasing power is still substantial. In terms of constant (1969) dollars, median money income increased from about $5,000 in 1947 to $9,400 in 1969, about $200 annually, or a compounded annual rate of increase of about 3 percent over the period.

The general rise in family income was accompanied by an upward shift in the income distribution. This shift can be illustrated by the decline in the percent of families with incomes below $4,000 (constant 1969 dollars) between 1947 and 1969. In 1969, 15 percent of all families had incomes below $4,000 compared with 37 percent of all families in 1947.

This was graphically illustrated by the accompanying income distribution chart:

That trend helps to explain the upswing in the overall installation rate for automotive air conditioning, which increased by about 9 to 1 over the course of the decade, but it also underscores the changing role of the low-priced domestic full-size car. Air conditioning take rates for this class surpassed the industry average in 1967, and that trend continued into the 1970s.

Factory Air Conditioning Installation Rates, 1959 versus 1969
Brand 1959 Model Year 1969 Model Year
U.S. Domestic Industry Average 6.2 percent 54.0 percent
Chevrolet, full-size 2.3 percent 62.1 percent
Ford, full-size 4.0 percent 64.3 percent
Plymouth, full-size 2.3 percent 67.1 percent

 

What I take from this, as I’ve said before, is that by the end of the ’60s, more and more buyers regarded the full-size Chevrolet, Ford, and Plymouth not as low-buck basic transportation (a role that was increasingly being assumed by compacts, intermediates, and imported small cars), but as a less-expensive alternative to full-size mid-price cars, for people who didn’t care about or didn’t want the added prestige of more upscale brands.

In the short term, the latter still had lots of momentum, including strong dealer networks and considerable brand loyalty, but I think the data in this post is more evidence that the writing was already on the wall for their eventual decline in the 1980s.

Keep in mind that the above data is only for the United States: I don’t currently have this kind of data for Canada. However, Statistique Canada (CS13-542, Table 4) indicates that the median income of Canadian individuals and families in 1969 was only $6,801 CAD, equivalent to $6,316 USD at the time — about two-thirds of the median U.S. income in 1969. Since Canadian households had less income, it stands to reason that the installation rates of expensive options like air conditioning remained significantly lower than in the U.S. So, if any Canadian readers recall air conditioning still being very rare on low-priced big cars in the late ’60s and early ’70s, you’re probably right! This was another of the various differences between the U.S. and Canadian markets.
