How a Cold Climate Heat Pump Cut a Quakertown Homeowner’s Electric Bill by $300–$400
PROBLEM: Our homeowner was dealing with a major heating problem: his old 25-year-old heat pump was so inefficient that his electric bills were reaching nearly $1,000 a month. The system relied heavily on costly electric backup heat and simply couldn’t keep up with Pennsylvania winters anymore.
SOLUTION: To solve the issue, we replaced his outdated unit with a high-efficiency Daikin Fit cold-climate heat pump paired with a 97% propane furnace. This upgrade immediately slashed his utility bills by $300–$400 a month and delivered the reliable comfort his home was missing.
