How Allentown's Climate Affects HVAC Replacement
In Allentown's climate, the HVAC decision between gas furnace and heat pump depends on your home's specific heat load and gas availability. Modern cold-climate heat pumps (Mitsubishi Hyper Heat, Bosch IDS) operate efficiently down to -13°F and are viable primary heat sources. A hybrid system — heat pump for cooling and mild weather, gas furnace as backup below 15°F — provides maximum flexibility in Allentown's extreme cold.
