New LG Mini Split—Cools but does not heat?
Title mostly says it. Had a knucklehead contractor that installed this for me, and doesn’t seem to know what he was doing. One sob story after another, and now he has completely ghosted me, and so have limited information about what was and wasn’t done. I haven’t installed on myself, but am fairly handy and wondering if any ideas for troubleshooting before I call an HVAC company out. Hoping the brain trust has some ideas for me. Definitely learned my lesson.
Description of issue: New install LG 2 ton unit. Cooling works, but maybe not as well as I would have guessed. Temperature was about 20 degrees below garage (garage 65 here where we live.) The heat does not work at all—tried to turn it on and the unit never blew. The lines appear to have frozen when the heat setting was turned on, and the compressor was not engaging. This makes me think maybe a Freon leak when it was installed? Maybe the 4 way valve failed, but doesn’t seem super likely out of the box?
Any ideas of things to check for? If other problems are visible, please let me know so I can get a list together of what should be fixed. Be as mean as you want, I honestly think it would have looked better if I had just done it myself from the start but oh well lol.
