A single home upgrade can change how your house feels, how much you pay each month, and how exposed you are to rising energy costs. That's why one homeowner's candid breakdown of living with a heat pump in a 100-year-old house offers a useful look at what's possible, and what to plan for, when modern systems meet older homes.

In a detailed post in the r/TwinCities subreddit, a homeowner shared their experience upgrading their HVAC system in a 2,700-square-foot historic home. Their main question before making the move: "Would it work in a Minnesota winter?" 

The homeowner said they installed a 40MURA heat pump for $16,000 before rebates. Summer performance delivered immediate results: the system was "noticeably quieter than our AC," cooled the house effectively, and cost less to run. 

Winter was the real test. The OP's heat pump is connected to a furnace that automatically kicks in at low temperatures. But so far, the homeowner says it hasn't needed to switch over. 


Still, not everything has been seamless. The homeowner described a 15-degree temperature difference between floors and attributed the imbalance to ductwork that had been "set up for the air conditioner, and most of them point to the top floor." With the heat pump now sending warm air through the same ducts, it naturally accumulated on the upper floors. 

They also noticed that placing the heat pump in a closet off a home office made that space noticeably hotter and drier than expected, a reminder that layout and installation details matter just as much as the equipment itself.

Commenters jumped in with both advice and perspective on their own experiences. 

"Typically with the ducts in a house, there should be baffles that can be used to adjust how much air is being sent to different areas of the house," one Redditor offered
