Replaced a starter capicator, now it just bloweswarm air


On hot day your unit may not cool enough. Make sure that outside unit is clean, filter inside should be clean. If all above is good your unit may be low on Freon.

What happens when the pipe freezes?


low freon charge or your inside evap coils are dirty,,,check yourevap filter and replace if its dirty..also check your evaporater coils to see if its dirty,,,,,,,if its dirty you will need to flush and clean it...with coil cleaner and water......if all is clean and evap has good air flow..........your freon charge might be low......check your pressures hi and low.........hi side should be around 220 to 250 psi and low side should be 68 to 74 depends on the outdoor temp and indoor temps............have a certified hvac tech check the pressures.............

high side line is the small copper line
low side line is the bigger copper line............

a feedback would be good if this helps anyone...

18 year old Janitrol Heat Pump freezing up.


i would get someone to check your refrigerant levels have you ever had the evaporator coil flushed and cleaned? proper refrigerant levels and proper airflow across coils are extremley important not to scare you but 18 yrs is a long time on a heat pump 9-12 years is the point where they really loose there efficiency going for a newer one would probably cut your operating cost in half if not more depending where you live there are a lot of people not familiar with heat pumps so i suggest finding a company that specializes in them to service your unit

Air conditioner wont cool house


Could be low on refrigerant or stopped up evap coil. Dirty outside condensor. Just some thing for you tp check. Take a thermometer and measure the intake air and the closet outlet. subtract the difference is Temp Difference. Should be about 18 to 21 degrees. IOf lower than 16 degrees have a service tech to check it out. Russ

AMANA PTH153B35AE PTAC Temp drop??


PTAC temp drop should be 20 to 25 degrees across the coil. They never put a service tap on these units. I sell Amana PTACs. You may be alittle low on gas. Check your air TD and that will tell you. The compressor may be overheating due to lack of cool gas to cool the comp. May need a service tech but get a free estimate first. Rus

Air conditioner constantly running, not cooling house


Check and see if it is froze up. Check big line at outside unit for ice. check filter and replace as needed. Check outside fan to see if it is running. Wash out outside coil If fan and compressor are running and has hot small line at outside unit. If not froze up and coil is clean you will need to call in a pro. If compress over heated you may need to wait for it to restart if coil was dirty. Again make sure out door fan and or unit is running and clean.

Ac not blowing cold after outside temp reaches 98 degrees


Sounds like you have dirty condenser coils. Remove the upper shroud and check the condenser for clean. Take a water hose and gently spray out the coils paying special attention not to bend the coils over with too much pressure. This will allow more air movement through the coils and give you better cooling efficiency.

Hope this helps,

GSH13 Goodman heat pump split system is running a long time in cooling mode and will not cool below 74 degrees. A lot of condensation generated. The low side pressures 78 to 81 and high side pressures are...


Check sub cooling and super heat. the New ac units are very critical to charge. There is a charging chart on the inside of the cover to the unit outside. Check temp difference across coil. Should be 18 to 22 degress. If you have an ampmeter. Check the heat strips one 5 kw might be stuck.(sequencer). This would cause you not be able to pull down temp. Goodman unit are hard to charge to get the temp difference across coil. Feedback please

Cooling problems


Check the filters inside and the evap coil to make sure it isnt filthy. The evap coil can be cleaned with a credit card if its wet. The large line outside should sweat all the way to the compressor if its got enough freon. Will freeze when its cool outside or not sweat at all if its low. Good luck with it.

Water is not dripping from window A/C unit, air is cold but damp


HELLO .. HOPEFULLY YOUR UNIT SLIDES OUT OF THE A/C HOUSING, IF IT DOES REMOVE IT. (THERE MAY BE A FEW SCREWS HOLDING IT IN PLACE USUALLY BEHIND THE FRONT GRILL) PUT DOWN SOME OLD RUGS FIRST AND HAVE SOMEONE HELP YOU SLIDE IT OUT. GET OT THE GARDEN HOSE AND SPRAY NOZZLE. PROP UP THE FRONT OF THE UNIT SO IT DRAINS TO THE REAR. BOTH THE EVAPORATOR COIL AND CONDENSER COILS SHOULD BE CLEAN. YOU WILL NOT SEE DIRT ON THE OUT-SIDE OF THE COIL ... IT WILL BE ON THE INSIDE HIDDEN BY THE CONDENSER FAN BLADE. BE VERY CAREFUL NOT TO BEND THE FAN BLADE WHILE INSPECTING OR WASHING. BE EXTREAMLY CAREFUL TO COVER THE MOTOR AND ELECTRICAL CONTROL BOX WITH PLASTIC BAGS TO ENSURE ALL ELECTRICAL COMPONENTS STAY DRY. FACTOID: 90% OF AIR CONDITIONERS THAT "DONT COOL AS WELL ANYMORE" IS DUE TO DIRTY COILS. THERE IS ALSO A TUBE OR CHANEL THAT DRAINS THE WATER FROM THE EVAP (FRONT) COIL TO THE BACK OF THE UNIT. THAT CONDENSATE WATER IS SUPPOSED TO ACCUMILATE IN A SNALL RESEVOIUR WHERE THE SLINGER RING ON THE OUT SIDE COIL FAN BLADE PICKS IT UP AND HELPS COOL THE HOT CONDENSER COIL. SOME OLDER UNITS MAY NOT HAVE A SLINGER RING AROUND THE OUTSIDE OF THE BLADE. NOW ... MAKE SURE YOUR OUTSIDE FAN BLADE IS CLEAN. AS WELL AS THE INSIDE BLOWER FINS ON THE "SQUIREL CAGE". NOW THAT YOUR UNIT IS CLEAN AND YOU CAN SEE CLEARLY THROUGH BOYH COILS, GO AHEAD AND OIL YOUR MOTOR. CHECK TO SEE IF YOUR FAN MOTOR HAS "OIL CAPS" USUALLY THEY ARE AT THE TOP OF THE 2 ENDS OF THE MOTOR. IF THERE ARE CAPS REMOVE THEM AND USE A STRAIGHT WEIGHT (NON-DETERGENT OIL). SOME WINDOW A/C'S UNDER 12,000 BTU'S ARE SEALED UNITS. IN THAT CASE YOU WILL HAVE TO REMOVE THE UNIT FROM THE WINDOW MOUNTING BRACKET. AND FOLLOW THE SAME PROCEEDURE AS LISTED ABOVE. GOOD LUCK AND STAY DRY.
