What we did
This March, we replaced the existing heat pump at a home in Lancaster with a new unit. A heat pump handles both heating and cooling, so getting the installation right affects comfort in every season, not just one.
The installation involved a total line set length of 35 feet. Because line set length affects how much refrigerant a system needs, we added an additional 7 ounces of refrigerant to match this setup. Once the system was in place, we tested static pressure and measured it at .3, with airflow coming in at 1378 CFM. Those numbers tell us how freely air is moving through the ductwork and whether the equipment is moving enough of it to do its job.
Taking these measurements at startup is part of how we confirm an installation, rather than simply turning the system on and leaving. The new heat pump is fully operational and ready for use. For a Kentucky home that sees hot, sticky summers and cold snaps in winter, a properly charged heat pump with measured airflow gives the homeowner a solid starting point.
