Every home and situation is different so when planning for a new furnace there are several factors you need to consider.
You need to ask yourself about the fuel options available in your area.
Is the cost for the fuel relatively stable or does it fluctuate? This will maybe be the determining factor of whether to go with an electric furnace or gas. The other thing to consider is climate. If you have mild winters then an electric heater will work just fine but if the winters are harsh you may have to opt for a hybrid system to get the best out of your heat pump and your other alternative fuel source. The other thing is the cost of fuel, even your heating dealership would advise you to opt for the heat and AC product that will be more favorable to your pocket. You may also look into a system that saves you money not just on the upfront cost but also running cost. If so, how long will it take for the system to pay for itself, and if you plan on staying in that home long enough to reap the full benefits? You could easily make an informed decision by contacting a heating business and getting a professional to help you. Another thing to keep in mind is that you must have heating maintenance yearly to avoid preventable breakdowns. HVAC maintenance impacts the way your system runs and may also impact your energy bill. It may affect the number of times you will have to call an HVAC repairman for boiler repair. You could also take your time to make sure they are licensed and skilled enough to do your furnace/heater installation. You would not want someone who will mess up your hydronic heating system then you have to pay someone else to rectify their error.
