"If you’re looking for prompt, professional, and trustworthy service, look no further. The owner at Gonzo was very personable, and took the time to explain every step of their process in a way that I could actually understand (the communication was phenomenal). He also has an extensive background in the HVAC industry. Can’t recommend these guys enough!"

Heating and Air Conditioning FAQs, answered by experts

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.

Yes, HVAC zoning is generally considered worth the investment by both experts and homeowners. Zoned systems offer significant benefits in convenience, efficiency, and comfort by allowing you to set different temperatures for various rooms or 'zones' in your house. This ability to heat and cool only the spaces you're using leads to energy savings and lower utility bills. Zoned systems are especially effective in multi-level homes that experience temperature fluctuations, but even smaller homes can benefit from the ability to adjust temperatures more quickly. While the up-front installation cost can be high, many find it's a worthwhile long-term investment, particularly for those who plan to stay in their home for a while.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.
