Tip & How-To about Heating & Cooling

Window air conditioner blows warm

There are a number of things that cause a window air conditioner to blow warm air. None of them good. A faulty thermostat. A small leak which requires repair and recharge of refrigerant. A bad compressor. A bad capacitor. The list goes on.

As an air conditioning mechanic, I earn a good wage. Add cost of a vehicle, auto insurance, gasoline, cost of inventory, the person that answers the phone at the office, liability insurance, unemployment insurance, workman's compensation insurance, payroll taxes, taxes on inventory, my accountant's fees, my attorney's fees the donations to the local little league teams, cost to purchase and maintain my large number of highly specialized tools and instruments .... My hourly rate, depending on what part of the country I'm in, is at least $75.00. Add $25 to $75 for the most basic of parts. Your repair is going to run at least $100.00.

Unless your window airconditioner is a very large, commercial unit, it will be much less expensive and quicker for you to go to Walmart, Kmart, Target or the Big Box store of your choice and get another one.

AIR DOES NOT WORK DO I JUST NEED FREEON


If the air conditioner blow warm air,

1. Open the hood and check the fan belt first, sometime the fan belt broke caused the compressor stop to work, if the fan belt is good, check the compressor see if the center part turns, if turns, that means the compressor is o.k.

2. If both work fine, check the air conditioner small window see if there is bubble, if you see some bubbles in the small round window, that’s means your air conditioner lack
R-22 Freon.

3. before you fill up the Freon, check the leaking, if leaks, fix it and then fill up the Freon, the best way is to ask some professional auto air conditioner repair shop to help you.


Hope this can help you.
