The question we hear over and over is always the same: can the ducts be kept?\u003c\/p\u003e\u003cp\u003eOften, yes - at least partially. The \u003cstrong\u003e18,000 BTU GREE Airy R32\u003c\/strong\u003e moves \u003cstrong\u003e883 ft³\/min\u003c\/strong\u003e and operates at \u003cstrong\u003ehigh static pressure\u003c\/strong\u003e, allowing it to reuse an existing network where a low-pressure ducted system would not make it past the first branch. But a complete answer requires measuring rather than assuming.\u003c\/p\u003e\u003ch3\u003eWhat We Check on an Existing Network\u003c\/h3\u003e\u003ch4\u003eHow Much Airflow the Network Can Handle\u003c\/h4\u003e\u003cp\u003eAn 80,000 BTU gas furnace may have moved 1,200 ft³\/min through this network. An 18,000 BTU ducted system moves a maximum of 883. The network is therefore generally large enough - the opposite risk is the issue: oversized ducts create air speeds that are too low and poor reach in distant rooms. We rebalance the system, and sometimes reduce duct sections.\u003c\/p\u003e\u003ch4\u003eSealing\u003c\/h4\u003e\u003cp\u003eThis is the point that most often disappoints. A thirty-year-old network leaks into the crawl space or attic, and every percentage point of leakage is conditioned air that is paid for and then lost. Sealing the joints costs little and pays for itself faster than any efficiency difference between two units.\u003c\/p\u003e\u003ch4\u003eReturn Air\u003c\/h4\u003e\u003cp\u003eOlder forced-air networks often have one large central return. This works as long as bedroom doors have clearance beneath them. Otherwise, the closed room becomes pressurized and stops being properly served.\u003c\/p\u003e\u003ch4\u003eThe Plenum and Connection\u003c\/h4\u003e\u003cp\u003eThe indoor unit measures \u003cstrong\u003e44.48 x 29.69 x 11.81 inches\u003c\/strong\u003e. Connecting it to the existing plenum almost always requires a custom transition. This is a shop-fabricated part, not a catalog accessory, and it must be included in the quote.\u003c\/p\u003e\u003ch3\u003eCertified Figures\u003c\/h3\u003e\u003cp\u003eAHRI Certificate 216618234, ENERGY STAR listing 4514338.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSEER2 of 24.5\u003c\/strong\u003e - the highest cooling efficiency of the entire ducted-system range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEER2 of 14.0\u003c\/strong\u003e and \u003cstrong\u003eHSPF2 of 9.4\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-8 °C\u003c\/strong\u003e: 15,500 BTU\/h, COP of 2.86\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-15 °C\u003c\/strong\u003e: 17,000 BTU\/h, COP of 1.8\u003c\/li\u003e\n\u003cli\u003eDown to \u003cstrong\u003e-30 °C\u003c\/strong\u003e: 10,100 BTU\/h at maximum capacity\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAt -15 °C, the unit delivers \u003cstrong\u003e17,000 BTU\/h\u003c\/strong\u003e, more than at -8 °C and 94% of its rated capacity.

The ducted system heats the home for almost the entire season, the furnace handles peak demand, and you retain a second heat source in case of a breakdown. We only remove an existing system when it is genuinely at the end of its service life or when the space is needed.\u003c\/p\u003e\u003ch3\u003eComfort\u003c\/h3\u003e\u003cp\u003eMoisture removal of \u003cstrong\u003e3.80 pints per hour\u003c\/strong\u003e.
