I am new to this forum and this is my first post. I joined as I have not found any answers to my hvac question
I am currently in the market for a new central air system for my split entry home built in 1956 that is 1300 sqft. I have no duct work of any kind in the home. I will have new duct work, air handler etc installed in the attic and will only send air to my main floor. My current heating system which I plan on keeping and using uses a gas furnace with forced hot water through baseboard/radiators. In the quoting process two of the contractors suggested I add a heating element (furnace?) to the central air system to provide heat as a secondary source, i.e. as a backup to my current system. They will run a gas line to the attic where I presume they will install another furnace. I am not sure if I am comfortable with having a gas line to the attic but I presume if done properly like anything else it should be fine. I asked about a water coil instead of a furnace as they would not have to put a hole in my new roof but with New England winters they were hesitant The added cost to add heat is short money so that is not an issue.
My main question is, does it make sense/worth it to have a backup heating system?
Also, in adding a heating element to the system, will that take away the optimization of the cooling function which will be the main reason behind the install.
Please advise and Thanks your all your help
