Here’s the twist the Martins missed: It’s like judging a winter coat by how well it works in a rainstorm.
Chen laughed. “SEER is for summer. You bought a Ferrari for cooling and a golf cart for heating. I bought a Subaru—less sexy in July, but it climbs every winter hill.” The Martins learned the hard truth, which you can now learn for free: seer ratings for heat pumps
Don’t be Mark. Don’t chase a high SEER number like a trophy. Match the rating to your climate. A heat pump is a year-round appliance. Judge it by its coldest performance, not its hottest boast. Here’s the twist the Martins missed: It’s like
The Martins were sold. The install was clean. That August, the house felt like a wine cellar. Their electric bill dropped 30% compared to the window units. Mark posted a smug photo on Facebook: “Go big or go home. 22 SEER. #Winning.” You bought a Ferrari for cooling and a golf cart for heating
The comment section was a graveyard of warnings they ignored. One friend wrote: “Wait til January.” January arrived with a polar vortex. The thermostat read 28°F outside. The heat pump, which worked so beautifully in summer, began to struggle.
The Martin’s 22 SEER unit had a terrible (Heating Seasonal Performance Factor)—only 8.2. It was a cooling machine that could sort-of heat. For Vermont winters, they needed a cold-climate heat pump with an HSPF above 10 and a low-temperature rating. SEER had nothing to do with it. Act III: The Neighbor’s Counter-Story Across the street lived the Chens. They’d installed a heat pump the same week. Their unit was only 18 SEER —four points lower than Mark’s.
Logline: When the Martins moved into their drafty Vermont colonial, they thought a high-SEER heat pump was the ultimate flex. But as winter descended, they learned the hard way that not all efficiency ratings are created equal. Act I: The Summer of the Big Number Mark and Lisa Martin were tired of window AC units roaring in every bedroom. Their HVAC contractor, a smooth talker named Dave, pitched a solution: a new ductless heat pump system with a SEER rating of 22 .
