You can find the best HVAC and AC contractors in San Francisco by performing an online search. By viewing the top-rated local pros online, you can easily compare ratings and Top Pro statuses. You can also easily access customer reviews, as well as customer-provided photos of actual work done by the contractors.

It’s also helpful to check the contractors’ qualifications. Find out if the pros you’re considering have any credentials, certifications or licenses. For example, you can visit California's Department of Consumer Affairs website to look up HVAC and AC pros and find out if they’re licensed. 

Once you’ve identified three to five pros who seem like a great fit for your project, start asking them for free estimates. Compare the prices you receive to help narrow down the search. In the end, choose a HVAC contractor you believe has the best reviews, the most experience and the fairest prices for their services.

For some California coastal cities — like San Francisco — central air conditioning is rare. The city does not commonly experience high temperatures, and ocean breezes and fog keep the weather famously chilly. 

Still, the city does occasionally experience heat waves and record temperatures. If you want to ensure you’ll stay cool during the city's hottest days, air conditioning might be worth the cost. Contact San Francisco’s best HVAC pros to get free estimates and learn more about your options.
