    The reason the rules say no pricing exactly for things like this. There's lots of ways to price. One company charges huge mark ups on the cheap parts that fail often but bids systems so low that...

    That's exactly right. A restriction can act as a metering device. Can't get any more specific since someone reading this might try and DIY which is not allowed here.

    Sound like it's going to be expensive. You have at least one restriction, the liquid line can not be cooled lower than the 95 degree ambient air. Root cause is the poor install.

    Call the dude back that was there 2 weeks ago. I warranty any work performed, as does most everybody.

    Doesn't sound like a compressor issue to me either. You lost all the refrigerant so there's a leak somewhere. I would not advise a high dollar repair on a 15 year old AC.

    liquid line colder than ambient. Temp drop across the drier?

    Have someone add return air to the basement and keep it low to the ground. With the fan on it will greatly help even the temperatures.

    If it can get to 72 it's not undersized. Have the stage delay timer disabled and use temperature differential for staging.

    Turning the breaker off is a good idea if you don't need heat now. It will have to be repaired before AC season or your bills will be crazy high with heat and AC running at the same time. If the...

    Did it keep the house at set temperature the previous 6 summers? If so then have it repaired. Also check on how much price difference between a new coil and a new air handler, often times it's not...

    Not allowed and dangerous. Your 80% furnace flue was a negative pressure so the units could be common vented. The PVC flues are positive pressure. Since air will take the path of least resistance the...

    X3 on good tires. Sliding around on 1/2" of snow sounds like you're way over due for some new rubber. When it gets 8" or more deep I throw a set of chains in the van. They help a bunch on those long,...

    No you didn't damage the motor. It's designed to handle that or else customers would need a new inducer assembly any time the drain line plugged up.

    Gravity is the force that causes the water to...

    The v drive motor tells the control board that it's working too hard. The board then slows the blower so the motor isn't damaged. The furnace also has a temperature limit switch that shuts the fire...

    Over heating and low air flow go hand in hand. Checking total external static pressure (TESP) takes 2 minutes or less. If it runs fine with no filter I'd guess you're lacking enough duct for the...

    It happens. Got three out there right now with cracked exchangers that second opinions called good. Some folks think an exchanger is fine so long as the roll outs are not tripping. That's not how I...

    Leave it alone for now and start saving for a new furnace, could be several years before needing replaced. Make sure to get the annual service done in the fall so when the bad news comes you have...

    Switch to emergency heat and call on Monday. Many heat pumps don't have a low pressure switch and will run even though all the refrigerant leaked out.

    Shoot for 350-400 fpm of air through the filters so they don't plug up so fast.
    Figure out if those filters get it or if two are needed to get the required surface area .

    Those coils run quite a bit colder than the ambient temperature so at 40 outside there will be frost. The units are supposed to go into a defrost mode to clear it off.

    Just for a little perspective that would be a 100,000 BTU furnace only running for 7.9 hours a day. If you're not living there I'd suggest draining all the water from the house and turn the heat off.

    Combustion appliances need a specific amount of air to burn correctly. When there's not enough combustion air in the area it has to be brought in, sometimes using outside air . Using a window would...
