R-22 home condenser unit low side and high side pressures when running


Pressures look good but to know if it is charged correctly you have to do a sub cool or superheat to know for sure. Rule of thumb is if turn unit it on let it run 10 minutes. If the suction line sweats and is cold. Might be proper charge.

I have a Ruud 2 ton split system and the system will not cool. The compressor and fan on the outside unit works and the fan blower on the air handler works too. The temp on the lines coming into the...


The small line coming in from the outside unit should be warm to hot and the larger line should be cool and sweating with water forming on it. I am taking for granted that the unit was working if so it sounds as if the unit is low on freon. your inside coil should be sweating a lot from top to bottom if it is only cool or sweating on the bottom but less to nothing up top you are low on freon. When very low the unit will stop working just like a broken valve in the compressor. If it is just a little low it will not cool properly and at night it might even freeze the inside coil up.

99 rodeo ran out of gas now no start


If you can hear the pump run and you get no fuel its the pump, If it blew the fuse i would say the pump tied up. That happens when you run around on empty a lot, gas is what keeps pumps cool when you run under 1/8 of a tank pump is not submerged in gas to keep cool hense pump burns up.

Heat Pump


Your inside cooling coil in the air conditioning mode could be frozen over. Change the fan setting to on and operate it that way when in the cooling mode. Turn the air conditioning OFF with the fan ON to clear the coil of frost which should take about 1 hour.

The fact that you have sweat on the large line means that the temperature of the gas inside the line is below the due point of the moisture in the air. A good tech would measure the pressures and temperature of the system to get what is called superheat to determine proper system charge of refrigerant.
