Turn off power, then remove the front cover. The nameplate is on the chassis, usually on a side panel or near the control box. Some older units also carry a label inside the front cover. Copy the full model number, including letters. If the label is missing, check a matching unit in another room, or measure the sleeve and photograph the unit. More on finding the model number.
In most cases, yes. Applied Comfort builds PTAC chassis to many legacy sleeve sizes, including 32, 36, and 44 inch widths and three-piece K series installations. The new chassis slides into your existing sleeve and uses your existing grille, so there is no wall work. Send the sleeve width, height, and depth with the old model number. See Applied Comfort legacy units.
McQuay, now Daikin Applied, ended its PTAC line in 2014. Replacement chassis for discontinued McQuay, Singer, and Remington series are built by Applied Comfort to the original McQuay sleeve sizes, in electric heat, heat pump, and hydronic versions. See McQuay PTAC replacement.
Read the voltage on the old unit's nameplate. Then check the receptacle: a NEMA 6 receptacle is 208/230V and a NEMA 7 receptacle is 265V. Many 265V units are hardwired with no plug. Hotels and high-rise apartment buildings often run 265V. A 208/230V unit does not run on a 265V circuit, so confirm before you order.
Yes. PTACs are set up for 15, 20, or 30 amp circuits, and the amperage limits how much electric heat the unit delivers. Match the new unit's power connection to your existing receptacle and breaker. If you want more heat than the circuit allows, plan for electrical work first.
For rooms heated all winter, a heat pump usually costs less to run. Heat pump PTACs deliver roughly three to four units of heat per unit of electricity at rated conditions and switch to electric backup only in the coldest weather. Electric heat costs less up front and suits rooms that rarely need heat. Compare heat pump and electric heat.
Pipes connected to the unit mean hydronic heat: a hot water coil fed by the building boiler. The replacement should be a hydronic unit with the coil in the same position, top or bottom, so the piping connects without rework. Applied Comfort builds hydronic replacements for standard 42 x 16 and legacy sleeves.
Yes. GE has used the same 42 x 16 sleeve since 1961. Current AZES electric heat, AZHS heat pump, and AZVS variable speed units slide into older Zoneline sleeves. Check the sleeve floor for rust and the outdoor grille for damage before installing. See GE Zoneline replacement units.
Units ship by freight from the Air Distributors warehouse in Louisville, Kentucky, or direct from manufacturer stock, to any address in the Philadelphia metro and South Jersey. Tell us about loading docks, liftgate needs, freight elevators, and delivery hours on your quote request. See service areas.
Standard 42 x 16 units are usually in stock at the distributor or manufacturer. Many legacy chassis are built to order and take longer. Your quote includes the expected lead time. If your building runs on legacy units, keep one or two spares on site so a winter failure does not leave a room without heat.
No. Air Distributors is a wholesale distributor. It supplies the units, and your maintenance staff or HVAC contractor installs them. Most replacements on an existing sleeve are a chassis swap that a maintenance technician handles. Hardwired units, electrical changes, and hydronic connections need a qualified technician.
Yes. Many quote requests are for one failed unit. Send the model number, sleeve size, voltage, and heat type, and you get a quote for that unit. If more units in the building are the same age, ask about a phased plan at the same time.
Yes. Contractors source replacement units for their customers' buildings, including help matching legacy sleeves and discontinued models. Use the quote form or call with the job details.
The right unit depends on your sleeve, voltage, heat type, controls, and quantity, and freight depends on your address. A quote built on those details is accurate. A list price is not. Request a quote to get pricing for your building.
Replacement units carry the manufacturer's warranty. Terms vary by brand, series, and component. Ask for warranty details with your quote, and register units with the manufacturer when they are installed.
