Yes, based on the information provided, it seems that you would need a 110 amp breaker for your unit. Let's break down the calculation:
Heat Strips: The AC guy mentioned that your unit has 70 amp heat strips. Heat strips are used for heating purposes, and they draw a specific amount of current. If you have 70 amp heat strips, you need to account for this in your breaker sizing.
Heat Pump: Additionally, the AC guy mentioned that your unit has a 40 amp heat pump. The heat pump is also a component that requires power, and its current draw should be taken into consideration as well.
To calculate the total amp requirement for your unit, you add the current draw of the heat strips and the heat pump together:
Total Amp Requirement = Heat Strip Amps + Heat Pump Amps Total Amp Requirement = 70 amps + 40 amps Total Amp Requirement = 110 amps
Therefore, to safely accommodate the current draw of your unit, you would need a 110 amp breaker.
Keep in mind that this calculation assumes that the heat strips and the heat pump are running simultaneously. In most cases, the heat pump and heat strips will not run at the same time, as they serve different purposes (cooling and heating). However, it's essential to have a breaker that can handle the combined maximum load of both components for safety reasons.
