    Frequently Asked Questions for Heating & Air Conditioning in San Francisco, CA
    Q: What are clients of Diamond Certified hvac contractors saying about contractors in San Francisco, CA?
    A: Verified Altai Mechanical Customer, 1 of 10
    "We were in this horrible limbo with Bayside Mechanical, who said they would replace our heat pump in 10 weeks, but we still had not heard back from them even 4 months later. We found Altai's contact info through a recommendation from a nearby heat pump salesperson and Altai Mechanical had our heat pump installed roughly 10 days after our initial conversation. Altai is knowledgeable, friendly and committed to making the customer happy. I have recommended him to anybody I've spoken with who is looking for a new heat pump I really like how Samir took the time to explain what he planned to do. He explained our options to us, explained how we could save money by picking certain units and worked tirelessly to install our heat pump. This gave me very high confidence in his honesty and abilities" - Nicholas H.

    Verified Schmitt Heating Company, Inc. Customer, 1 of 314
    "When they came to look at our heating, they explained in layman's terms how the forced air heat would be installed. Their knowledge sold me compared to other companies. They were efficient, came on time, and kept things clean. They always informed us of what they were doing and kept us up to date." - Jane B.

    Verified Heating and Air Experts LLC Customer, 1 of 97
    "I would say they were knowledgeable and got the job done. I spent a great deal of money on it, but it is the original air conditioner for the house 89-90, not an inexpensive fix. At a minimum, if they need that type of work, give them a call. I am happy with the work they did and their professionalism. They were nice young men and knew what they were doing." - June W.

    Verified Galaxy Heating & Air Conditioning Customer, 1 of 84
    "They are the best of the best, top tier. I used to be in the trades and I think they are exemplary. You won't notice they are there. They are really good people, no loud music and clean up after themselves. Their willingness to listen and work with me instead of selling a product, I self diagnosed the problem and instead of doing it their way, they listened, tested my theory and that was the problem. I ended up saving thousands of dollars and they considered my input of value. The level of care" - Matthew S.

    Verified Ortiz Heating and Air Conditioning Customer, 1 of 244

    Q: What are some of the most popular brands that Diamond Certified hvac contractors use when working with San Francisco residents?
    A: Diamond Certified hvac contractors use top-quality brands like Fujitsu, York, Ruud, Lennox and Johnson Controls.
    Q: What types of HVAC troubleshooting do hvac contractors offer?
    A: HVAC contractors offer a variety of cooling system installations, including central air conditioning systems, window air conditioners, ductless mini-split systems, and heat pumps. Central air conditioning systems are the most popular option, as they are connected to a home's ductwork and are capable of cooling an entire home at once. Window air conditioners are a more affordable option and are easy to install, but they are limited to cooling one room at a time. Ductless mini-split systems are a great solution for homes without ductwork, as they can be connected to wall-mounted air handlers or ceiling-mounted cassettes. Heat pumps are a great option for mild climates, as they can both heat and cool a home.
