How a Heat Pump Works β€” A Simple Guide for Homeowners


🌑️ Introduction

You’ve probably heard that heat pumps are energy-efficient and ideal for homes β€” but how do they actually work? At Climatisation Applewood Quebec Inc., we believe educated customers make smarter HVAC choices. Here’s a simple breakdown.


πŸ” What is a Heat Pump?

A heat pump is a two-way climate control system that can both heat and cool your home. It works by transferring heat rather than generating it β€” making it far more efficient than traditional systems.


🧊 In Summer: Cooling Mode

  • The heat pump absorbs indoor heat
  • Sends it outside through refrigerant lines
  • Blows cool air inside via the indoor coil and fan

In effect, it works like an air conditioner.


πŸ”₯ In Winter: Heating Mode

  • The system reverses
  • Absorbs ambient heat from outside air, even in sub-zero conditions
  • Compresses it to increase temperature
  • Delivers warm air inside the home

Modern cold-climate heat pumps can extract heat even at -25Β°C, making them perfect for Quebec winters.


βš™οΈ Components Overview

  • Outdoor Unit (compressor + coil)
  • Indoor Unit (air handler + coil)
  • Refrigerant Lines
  • Reversing Valve (switches heating/cooling modes)

βœ… Why Heat Pumps Are a Smart Choice

  • Energy-efficient: Use electricity, not fuel
  • Eco-friendly: Lower carbon emissions
  • Dual function: Heating and cooling in one system
  • Rebates: Eligible for energy grants in Quebec

🧠 Applewood Tip:

β€œIf you’re switching from oil or electric baseboard heating, a heat pump can cut your heating bill by 30–50%.”
