AC Doesn't Cool

What to do when Room Air Conditioner Doesn’t Cool

If your room air conditioner doesn’t cool then you may need to clean it or recharge it with refrigerant. You can clean an air conditioner yourself by disassembling the unit yourself or you can call a professional. But before doing the job yourself you need to read the system manual and make sure you have the right skills and tools to do the job. Here is what you may need to do:

• 1) Unplug the unit and remove it very carefully from the window or the wall and place it somewhere outdoors where you can work on it.
• 2) Remove the grille and filter and unscrew the metal case while making sure that you do not damage the coil’s fins.
• 3) Wash out the filter or replace it with a new filter.
• 4) Clean the inside coil’s fins by using a vacuum with a soft brush attachment
• 5) From the fan side, spray water back through the fins. You will have to protect the wiring and motor with plastic.
• 6) Clean the unit up with a rag and allow the system to dry completely.
• 7) You can also lubricate the motor as per the “Repair and Care” manual’s instructions.
• 8) Then reassemble and reinstall the unit.
  

If that does not do the work then clean the evaporator and condenser coils. If it still doesn’t works then you may have to call some professional or call the company’s customer care.

Crash Course in geothermal heat pumps!

Found a website with some great information on geothermal energy! A lot of helpful graphs and visual aids. Just a snippet below, but you can view the full website at http://www.fossilfreedom.com/geothermal.html

"Studies show that approximately 70 percent of the energy used in a geothermal ground contact heat exchange heating and cooling system is renewable energy from the ground. The remainder is clean, electrical energy which is employed to concentrate heat and transport it from one location to another. In winter, the ground soaks up solar energy and provides a barrier to cold air. In summer, the ground heats up more slowly than the outside air.

Ground contact geothermal systems do the work that ordinarily requires two appliances, a furnace and an air conditioner. They can be located indoors because there's no need to exchange heat with the outdoor air. They're so quiet homeowners don't even realize they're on. They are also compact. Typically, they are up to six times less expensive to operate since they are far more efficient then any fossil fuel based system."

TAMPA - As those high summer temps continue, so do the high electric bills. So how would you like to cut your air conditioning bills in half? One Bay Area company says it can help you do it by tapping into the earth. It's called a geo-thermal AC system, and it could bring savings of thousands of dollars a year.

Geothermal Put Simply

While temperatures above ground change a lot from day to day and season to season, temperatures in the upper 10 feet of the Earth's surface hold nearly constant between 50 and 60 degrees Fahrenheit. For most areas, this means that soil temperatures are usually warmer than the air in winter and cooler than the air in summer. Geothermal heat pumps use the Earth's constant temperatures to heat and cool buildings. They transfer heat from the ground (or water) into buildings in winter and reverse the process in the summer.

According to the U.S. Environmental Protection Agency (EPA), geothermal heat pumps are the most energy-efficient, environmentally clean, and cost-effective systems for temperature control. Although, most homes still use traditional furnaces and air conditioners, geothermal heat pumps are becoming more popular. In recent years, the U.S. Department of Energy along with the EPA have partnered with industry to promote the use of geothermal heat pumps.
