Fixing My New Refrigerator

Nearly four years ago, I purchased the refrigerator of my dreams. The spacious, sleek, and stainless steel refrigerator contained built-in ice and water dispensers on one of its doors. Besides having two doors, this stylish appliance also contained two pull-out drawers. The first drawer kept fruits and vegetables crisp and fresh. The second drawer functioned as the freezer. Unfortunately, the freezer began accumulating excess frost soon after I purchased the refrigerator. I immediately called a technician about the problem. This individual quickly came to my home and diagnosed my problem. After a small repair, my freezer worked correctly. On this blog, I hope you will discover the importance of solving problems with your kitchen appliances quickly. Enjoy!

What Can Cause Your Home's Air Conditioner To Only Blow Warm Air?

Having an air conditioner that blows only warm air can be an aggravating problem. Knowing what causes the problem and what you can do about it may help you fix and maintain your unit through the summer.

What can cause your home's air conditioner to only blow hot air?

Your home's air conditioner may blow warm air for many reasons. Some of the most common reasons that air conditioners stop blowing cold air include:

  • Clogged air filter. The air filter for your HVAC system cleans the air before it reaches your home's air conditioner unit. If the air filter becomes badly clogged, air from the return air duct cannot reach your air conditioner, which can negatively impact the entire air conditioning process.
  • Blown circuit or loss of power. The part of your air conditioner that cools the air (the condenser) is separate from the part of your HVAC system that blows the air through your home. If the condenser loses power, the blower may still be functioning, which would cause warm air to blow through your home's vents.
  • Frozen coils. The coils for your home's air conditioner can actually freeze if they're worked too hard. When this happens, this sheet of ice would prevent your air conditioner from doing its job.
  • Lack of refrigerant. Refrigerant is the chemical inside your air conditioner's condenser coils that allows the A/C unit to cool down the home. Lack of refrigerant indicates there is a leak in your air conditioner.

How can you fix the problem your air conditioner is experiencing?

You can fix your air conditioner by systematically attempting to repair every possible problem that could be going wrong with your A/C. Follow this process:

  1. Check the power to the unit. Your home's central air conditioner probably has a dedicated circuit from which it draws power. Check your breaker box or your fuse box for a blown circuit, and restore the circuit if it's blown.
  2. Check and replace your air conditioner's air filter. The air filter is located in a slot between the return air duct and the blower. Remove the filter and check it for dirt. If it is dirty, replace it.
  3. Check for ice. Inspect all the parts of the air conditioner for visible ice. If you find ice on your unit, turn it off and allow it to thaw for 24 hours.
  4. Call an HVAC repair professional. If your air conditioner is leaking refrigerant, only an HVAC repair person will be able to fix the problem. If your trouble shooting doesn't fix the problem, contact an HVAC repair person for help.
