Can I call for furnace maintenance on a hybrid system?

Years ago I called my local, Terrell heating maintenance corporation about a possible hybrid heater.

This combines a gas furnace plus a heat pump. In Texas the freezing season is brief plus not too intense. A heat pump system works totally well for the heating function most of the time. When it gets below forty degrees, then the gas furnace is tagged in, then for Terrel living, that means I only use my gas furnace on the freezing winter season mornings, then most of the time the heat pump works for heating plus it is consistently used for AC. I love having energy efficient settings. Well the other afternoon I noticed that when my furnace was tagged in to supply heating, nothing happened. My heat pump ended up working double time on emergency heat. My energy costs started to skyrocket. What was wrong with the heating function? I had a moment of panic because I didn’t know who to call! Hybrid heaters are specialty items. Not every corporation sells them! Can I call for a normal Terrel furnace maintenance when the heat pump is paired with the hybrid system? Do all Terrel, TX heating suppliers do repairs on dual fuel systems like mine? I asked around plus found that not everyone is skilled in the section of dual fuel. I finally found a boiler maintenance corporation in Terrell that could handle both the gas furnace plus heat pump. They made the necessary repairs in no time flat. They also worked on my heat pump so I was nice for almost a whole year.
