When San Francisco experiences a heat wave like the one that hit last week, many local residents fantasize about having air conditioning to keep them cool. But even higher-end apartments in the city often don't have access to frosty A/C—and if you call SoMa home, having air conditioning will definitely cost you.

Using data from Zumper, a rental listings website, we took a deep dive to find out just how much an air conditioner is worth when it comes to monthly rents in SoMa.

For studios and one-bedroom apartments, we discovered that the median rent in SoMa is currently $3,875, making it one of the city's priciest neighborhoods. But for apartments that have air conditioning, the median price goes up even further, to $4,000. By comparison, studios and one-bedrooms without A/C rent for about $3,800. That's a price difference of $200 per month.

A SoMa Apartment with A/C: The "Budget" Option

For those seeking an air-conditioned apartment on a (comparative) budget in SoMa, a slightly more affordable option is 16 Jessie Street #207, which is on the market for $3,200—$800 below the median for apartments with air conditioning.

It's a furnished studio with one bathroom. Besides A/C, amenities include in-unit laundry, hardwood floors, a dishwasher, storage, high ceilings, and central heat. For those seeking outdoor space, there's a garden. Unfortunately, pets are not allowed.

According to the listing agent, the apartment's assets include "an incredible amount of sunlight, brand-new stainless steel appliances, cherry oak cabinets, large windows, and exposed brick and steel beams." There's also a rooftop deck with views of downtown, gas grills and "ample" seating. 

For a Few Dollars More: An Apartment with A/C Near the Median

If you've got a little extra cash to spend, take a look at 400 Beale Street, a one-bedroom with one bathroom going for $3,650 per month.

Besides A/C, apartment amenities include assigned parking in a garage, in-unit laundry, hardwood floors, a dishwasher, storage, and a walk-in closet. There's a balcony for a little outdoor space—but sadly, pets are not allowed.

According to the listing agent, 400 Beale Street's assets include "quick access to BART and Caltrain, a pool, a spa, a gym, security, and on-site management."

A Splurge Apartment with A/C

If money is no object, take a look at 338 Spear Street #26G, which is available for a pricey $4,295 per month.

This one-bedroom with one bathroom has luxurious amenities like assigned parking in a garage, in-unit laundry, hardwood floors, a dishwasher, storage, and a walk-in closet. But despite the higher price tag, pets are not allowed.

Its high-end building has equally high-end amenities, including a business center, concierge service, a residents lounge, dry-cleaning service, and a fitness center. Outdoors lovers can enjoy a swimming pool.

Here's what the listing agent has to say about it: "This full-service home is finished with Studio Becker cabinetry, Bosch and Thermador appliances, and custom lighting. This home is a pleasant walk to Union Square, world class waterfront restaurants, and the Financial District. Easy access to public transportation, 101, 280, 80, and and the Bay Bridge."
