The unit may be undersized,but there are other possible solutions.You can make sure you have good insulation in your attic for one.If the cool air can be kept cool longer the unit may be able to keep up.Getting double pane glass is another solution,and like the insulation will greatly lower your energy bill as well.make sure your exhaust,and return vents are open,and not blocked.The ventilation system could be undersized/clogged,or the fan may not be moving enough air through a properly sized system.There should be one speed for heating,and another (higher) speed for cooling.The outside unit may not be getting good air flow because of blockage from plant growth,or other debris.A outside unit in the shade will operate much better than one in direct sunlight.Just be sure it can get air if you place,or grow something there to shade it.Something directly over top of an outside unit will cause the air to recycle through the unit,making it less efficient.

Helping a friend install a new unit... he has 3 wires where we took out the old unit (the old unit had 4 wires) .. the (source) 3 wire is black, white & bare.... the old and new unit have black, red,...


Hello,

I suspect on teh wiring from the house the black&white will be the hot wires and the bare will be ground/neutral

use a volt meter before connecting tonew cooktop and check for;
black/bare to have 120volts
white/bare to have 120volts

if that is what you find...connect new cooktop as such;

black to black
red to (house) white

(cooktop) white and green to bare

Nuvi was locked by my 3 yr old. It is asking me to return to my security location, I have hit the reset button by the serial number and it still did not work. It is still locked.


Resetting the unit will NOT reset the PIN. Assuming your 3 year old had the presence of mind to enter the exact same 4 digits twice in a row (which is required to lock the unit with the PIN), simply take the unit to the area where your child locked it. This is the Security Location to which the unit is referring, and it will unlock allowing you to change or remove the PIN.

AC not cooling during the day


Your AC cooling efficiency is low when he ambient temperature is high and naturally it cools well when the outside temperature drops.

Please remove the filter on the grill and try to clean it under the tap water and after removing all the dust fix it back to the unit. This would increase the cooling efficiency of the unit.

Your AC is also five years old. Please avoid frequent opening of doors or windows.

Ensure that the exhaust fan and the blower of your unit are functioning normal.

The technician might not have done a proper job in fixing the area where the refrigerant would have leaked out. Please check the refrigerant pressure to ensure that no further refrigerant leak has taken place. Or even servicing your unit he would have punchered the tubes resulting in very slow leak of refrigerant resulting in no cooling or less cooling. It takes around a month to feel the pinch of it and the refrigerant. One fine morning after sometime the unit will run and it would start throwing hot air instead of cool breeze!

I recently bought a 4 ton 14.5 SEER Rudd Spilt system using R-410 and matching Rudd furnace. This system replaced a Lennox 10 SEER 4 ton unit. Now that it has gotten hot in Baton Rouge LA 90-93 degrees....


Sounds like the Unit might be low on charge.But without correct readings not sure.
The new unit with 410 will actually cool better due to higher boiling point temp. of freon type.Poor air circulation could also cause problem.Such as dirty filter, too slow fan speed,dirty coil.Also could have obstruction in freon lines either at pump,in line set,or in coil.
Get someone u trust to check it out and ask for their Rudd Dealership Training Credentials.

Fidgerdare electrtolux air conditioner


have you brought it down for a general cleaning on the 3 year period? if not then that's what it needs now.

the coil is freezing up because of dirt accumulation on the coil. even there is a filter, still with in 3 years it could have accumulated to decrease the airflow thru the coil and freeze it up.

tnx 4 using fixya,
