I think most people rent heater, but buy furnace because furnace can be used for over 10 years. If you pay $60/month, you pay $7200 in 10 years. A new one will not cost that much.
best furance is $5000. last 25+ years. warranty everything at least 5 year. Key parts for life. Yearly maintance visit $150.(you may do it every 2 years).
So nobody rent furance.
Thanks a lot. I suppose purchasing is still a better choice in respect of saving money. I also talked to a neighbor who rented furnace. She told me in the last 10 years she changed 2 furnaces in the old house. So she prefers rental to owning a furnace for the long run. I guess it really depends on how we perceive the thing and how long we want keep the house.
