Question about Air Conditioners

1 Answer

Lennox Elite Model # CB30M-65-4P I had my A/C fixed while back because the freon lines keep hitting each other from the vibration which causes a leak in the line every 6 months to a year and since then my heater does not work. It will not blow heat only cold air. It was working just before repair. I bought the home 2 yrs ago. can you also suggest what I might could do to keep the freon lines from hitting each other? because4 this is the last time they will be able to repair it next time I will have to replace the unit... Thanks

The copper the big line should have a insulating foam wrapped around it called rubetex which eliminates any rubbing. They should never be that close also. Now is this unit a heat pump?

Lennox Elite air handler will run cold for a while, then it will blow warm air out until the safety switch is moved, then it will make a noise in the system which sounds like air hissing, then the cold air...

sounds like installer broke on yellow wire between thermostat and condenser. your switch is breaking the 24 volt signal to cobdensor when the internal float is activated. moving the switch is somehow allowing bobber to drop enough to reactivate 24 volt and condenser comes back on. refrigerant starts to recirculate again and thats what your hearing in the lines. the switch prevents evap coil pan from spilling over into your return when the drain is clogged. use a shop vac and clear your drain. i blow it out with compressed nitrigen. after line is clear prime it wuth 32 oz of water.

About 6 LBS what you need to do is cut the lines back and Install a coupler and braze the lines together. Then hook your guages up to the system pull a 30 inch vacuum with a vacuum pump. Then you can start charging the system with freon liquid through high side guage and gas through low side guage. Charge the unit till the big line probably 3/4 inch sweats back to the compressor till a half dollar sized ring is on the compressor where the line goes into.Let me know

The fan is running and blowing cool air out of the unit but there is no air coming through the vents, what are the possible problems? (Lennox Elite series)

The unit could possibly have a frozen indoor coil. Turn ac to off...and fan switch to on...wait 45 minutes and see if air flow improves. Check for dirty filter which can lead to freeze up. Low on freon is also a possibility.

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.

Help. Wrong suction line installed on Lennox HS26-060

Call up the company that installed it. They should be responsible for the work even though it has been 7 years. And if they don't want to replace lines then try to offer to buy the new copper if they throw in the labor. Sounds only right to me. If the person that owns the company wants to keep Lennox warranty. I think they offer 10 years on compressor. But do it as soon as you can I am sure the small copper line is wrong size also. Good luck let me know how it goes. ken

I have a Coleman 5T 13 Seer Heat Pump. When the unit is running there is a lot of vibration (outside unit) and I hear a tinny sound (possibly like the fan hitting something). This seems to be worse...

First thing I would ask is did they locate the leak in the system before they recharged it? Your answer is YES to all three of your questions. If the unit is overcharged you can get what is called a liquid flood back to the compressor and this condition can cause compressor failure. Fans are balanced at the factory when manufactured. If a blade is bent or damaged it will throw it out of balance.
