According the psychometric chart the recommended Supply air temp. I did not have this problem prior to the new unit installation. Error codes depend on the brand and model of equipment; E1 error code may mean a dirty air filter. But as you can read in Pete's comments above, another explanation for an A/C unit that cycles between blowing cool then warm air can be a contol problem that is switching the emergency backup heat on - IF your system is a heat pump. Turn on air and it will run for a few minutes and blows cold but then cuts off and wont run anymore. The repairman says that there is a condensate collection pan as a part of the indoor unit in the attic of the house and that a drainage line is plugged, and the rising water level in the pan actuates a switch shutting off the fan/compressor unit situated outside the house at grade level. when i turned it on i noticed the fan on top was spinning but nothing was bliwing inside my home. Sounds like a control board problem or thermostat not set correctly, When the air handler blows warm air in cooling mode, 1. check that the aux heaters are not stuck "on", 2. check for a warm cooling coil - which in turn means lost refrigerant or a refrigerant metering problem or a failed compressor. If by "trapped duct" you mean ductwork is crimped that's repairable. . We have checked most of the duct work, but some of it is not visible. 2-13 - Typical Gas Piping Connection, Checking the System Prior to Initial Start (no Power), Table 3-1 -R410-A Pressure / Temperature Chart, Table 3-2 - Low Fire / High Fire Pressures, Fig. when I turned the unit on "cool", it started right up. Notice yesterday when I set the room thermostat to about 78 degrees a blue Aux Heat lite comes on. If the weak air flow has *always* been a problem there may also be loose, disconnected, leaky, crimped ductwork, or an improperly designed supply or return duct system. the ac guy showed up yesterday took the cover off went directly to the run cap. 0000014837 00000 n Warming up the air supply coming from your heating system may be as simple as re-connecting a loose or disconnected return air duct that is drawing too much cool air . Steve it sounds as if your compressor/condenser is probably working since you see intermittent cool air. I'd give your service company a call.

Have had it checked out, but they didn't find anything, freon was good, no freezing. 0000037051 00000 n if much insulation is lost, possibly un-wanted heat-gain into the blower compartment, increasing system operating cost during cooling season or vice versa, heat loss and higher heating costs during heating seasonAt DIRTY COOLING COIL / EVAPORATOR COIL - https://inspectapedia.com/aircond/Clogged_Evaporator_Coil.php we describe a blocked coolign coil and several problems that occur if insulation falls onto the cooling coil surfaces - on your system that might not be in the same area as the damage you describe.I wouldn't sweat a trivial nick or an inch of disturbed material but if the insulation is missing entirely over parts of the blower compartment or is loose enough to get drawn in I'd have it replaced. Can anyone tell me how to get back on the furnace/AC in the closet - and did the bully per chance just take out the cartridge to the AC on the roof without worry of electric shock? There's no problem with cooling or fan speed per se.Thanks in advance,Sam, On 2016-04-21 by (mod) Look for a condensate drain clog or pan leak. 0000017097 00000 n everything work but when you put it on cool it heat and when you put it on heat it heats. BUT: they said the heat to the Rheem and the furnace fan should still go on even if the roof AC was off. Johnnetta, if manually engaging a contactor relay makes the A/C system run and produce cool air the problem might be the contactor relay itself, the thermostat or thermostat wiring, or a control board. I don't know,Gary, but often when weather switches a heat pump over to backup heat we find operating defects in the backup system that were there for a long time but never evident because the backup wasn't in use. Many A/C system air handler units include a condensate overflow pan switch that will sense a rise of water in the condensate pan and shut off the air handler unit. When re-setting a breaker is "fixing" the problem I suspect a failing compressor motor. (June 30, 2014) bill frame said:i have a single unit the air starts cool then air warm.

Since your backup heat is a gas fired furnace it's being controlled by- a circuit board in the heat pump that switches over to backup mode- normal gas furnace controls including a limit switch on the furnace. Manual operation of contactor fires up compressor okay. Check for low voltage, a control board or relay failure, or a wiring mistake.
