You can use the existing ducting in your home with a new heat pump installation. A central heat pump can distribute warm air throughout your home this winter. If you need to replace an old furnace, a heat pump could be the perfect upgrade. Let’s look at when you should consider a heat pump and help you prepare for a safer and more comfortable home.
Will Your New Heat Pump Work with Your Current Ductwork?
A heat pump can connect to existing ductwork if the system is correctly sized and in good condition. Your system might need some modifications to ensure adequate airflow and minimize energy loss.
- Duct Size: Modern heat pumps may require significantly more airflow (CFM) than an older furnace-based central air system. This is because heat pumps transfer more air at lower temperatures to heat your home. The system could produce 1.5x to 3.0x more airflow than a furnace system.
- Leakage: You will need to replace any damaged sections to ensure efficiency. Your HVAC installer will check for damage, cracks, poor seals, blockages, and insulation problems.
- Material: The duct should be rigid sheet metal, like galvanized steel or aluminum. Some fiberboard ductwork systems are compatible with heat pumps, but will require a detailed inspection to ensure they can handle the airflow without creating excessive static pressure.
- Flexible Ductwork: Flexible ducts aren’t suited to heat pump systems due to their high level of airflow resistance and likelihood to restrict air when they kink or sag. Flexible ducts should only be used in transition areas where rigid ducting isn’t feasible.
If your old ductwork was installed within the last 20 years, there’s a high likelihood that it will be compatible with a new heat pump installation in Suffolk County.
What are the Options to Upgrade Ductwork for a Heat Pump?
There are solutions if your current ductwork can’t handle a heat pump’s higher airflow requirements.
- Duct Sealing and Insulation (Minor Project): If your system is compatible but has some damage or leaks, your heat pump installer can seal the leaks (usually with mastic paste) to improve airflow. Insulation can also be retrofitted to your ductwork to improve overall thermal efficiency.
- Duct Modification or Replacement (Moderate Project): Flexible or low-quality fiberboard ductwork can be partially replaced with rigid metal ductwork. Some vents might also need replacing with larger alternatives. This directly addresses airflow bottlenecks in the system.
- Partial System Replacement (Significant Project): A partial system replacement would involve removing and replacing main trunk lines (the largest segments connected to the air handler) to improve airflow and ensure efficiency. This will guarantee the necessary airflow and low static pressure to provide consistent heating throughout your home.
Sometimes modifying or replacing your ducts isn’t feasible within your budget, but you could still switch from a furnace to a heat pump by choosing ductless mini-splits. These units don’t use ducts and can be strategically placed around your home to provide zone-controlled heating whenever you need it.
