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.

Q: Can Diamond Certified hvac contractors work with Carrier products and similar items so I can get HVAC ductwork in San Francisco?
