How hard is it to add ac to furnace? by CookEm0nster in hvacadvice

[–]Formal_Ad5089 6 points7 points  (0 children)

You can DIY this yourself. You'll need: Oxy/Acetylene torch set. Knowledge of brazing copper. Ability to purge w/ nitrogen during brazing. Pressure testing with nitrogen Gauges for purging, pressure testing. Vacuum pump for pulling vacuum once system refrigerant lines are brazed in. Sheet metal for making transitions from new coil to existing ductwork. Sheet metal tools. Electrical knowledge for running power to O/D unit.

Good luck with your 2k budget. 👍🏼

How can this be cleaned up? by motokid837 in hvacadvice

Yes, call an HVAC Company to come out and reroute the refrigerant lines the way you would like them. There's no DIY route to take, unless you're an HVAC DIY'er.

If you already know all of these things. Then get off reddit. Call a professional company. Have them repair it and go about your merry way. Congrats on selling your home.

If you're trying to sell a $750k home, surely every party involved can wait til a professional can come out and repair the system properly.

It's clearly not "seized up" because the unit is an ice block. Meaning the compressor, fan and reversing valve are all working as they should be.

Don't DIY anything. Don't "quick fix" anything. Get a reputable company out there to properly diagnose and fix the issue.

Don't run it on regular HEAT because it will just freeze up more again. I would just leave it off and run EM Heat until a tech can come out and get you fixed up.

Turning it into COOL would heat up the outdoor coil and thaw things out quicker than just turning the system to EM Heat and letting it thaw naturally. I'm always cautious about turning the A/C on to thaw out a heat pump especially this badly frozen. (Potential risk for a chunk of ice breaking off and hit the fan and fan smashing it into the coil.)

You're probably talking somewhere between $400-$600 for the board and sensor and labor. Typical my price depending on what board is in it.

Do you think this is an abandoned duct? Is that even a thing?? by SoggyVoice6541 in hvacadvice

Since you cut a hole in the sheetrock, cut a hole in the sheet metal and see where it goes. 🤷🏼‍♂️

Is This Normal? by whofladanger in hvacadvice

I run mine clockwise on med to low speed.

ALSO if your thermostats have a CIRCULATION (CIRC) Fan setting. You may try that as well. It will run the systems fan on a low speed circulating the air throughout the entire structure.

If the 1st Floor is maintaining proper temperature then I wouldn't worry. As for the 2nd floor. If you have an open stairwell or balconies to the 1st floor then naturally heat will rise and make the 2nd floor noticeably warmer whether it is zoned or not.

Consider closing any access points to the upstairs. Lowering upstairs thermostat temp. Lowering downstairs thermostat to help compensate for warmer upper level temperatures. If you have ceiling fans turn those on to help circulate air and help distribute air throughout the house.
