Home Air Conditioning Informative - How To Check Your Home Air Conditioner And Save Money
We are in the middle of summer so now is the time to check your air conditioners performance. Anybody can do it and it costs only a few dollars. Here's how: Go to any dollar store or hardware store and purchase 2 cheap glass thermometers. Tape 1 on the air conditioner unit's air return grill (where the filter is) tape the other thermometer on the farthest air duct register (vent). Turn your temperature down to 70 so it will run longer. After 1 hour, and while the air is running check each thermometer.
There should not be more than 20 degrees difference between the two. If not your good, if so you might need more freon and/or need to have the coils cleaned. Always ask the technician to clean your coils when they come (you will know if they did or not because the smell of the cleaning spray will come out of the vents). I recently had my coils cleaned and the tech threw down a 2 inch think blanket from the roof, I thought it was a filter. It was actually on my coils blocking the airflow and was a "filter" made of compacted dust and who knows what.
After removing the blockage and cleaning the coils, the air coming out of the vents increased dramatically and the house cooled down much quicker and the AC unit ran less. Give it a try.
