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


Crash Course in geothermal heat pumps...
"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.

Cost of Geothermal Heat Pump

Utilizing free energy from the earth beneath your feet, it is undeniable that geothermal is environmentally friendly and responsible. Geothermal heating and cooling uses the relatively constant temperature of the earth to heat and cool homes and businesses with 40% to 70% less energy than conventional systems. It also has the added benefit of providing free domestic hot water during the summer season and reduced cost for domestic hot water during the winter. All of these benefits sound good on top of "going green" but it all comes down to one final question. How much will this cost? Is geothermal "green" in both an investment perspective as well as an environment perspective?

Installation for geothermal heat pumps does have a high upfront cost. There are a lot of variables--where you live, the ground to be drilled, the square foot of the house--and though everyone agrees about its high initial expense, exactly “how much” remains vague at best. A good general idea for cost would be twice the price of a regular heat pump system with air conditioning. A geothermal heat pump costs about $2,500 per ton of capacity, with the typically sized house needing a three-ton unit and putting the cost at roughly $7,500. Installation can bump the costs up to $10,000 or more depending on depth of pipes, type of equipment, and soil conditions.

On the flip side, the geothermal heat pumps offer high efficiency and low operating cost. Savings on the electric bill are immediate and considerable. According to the EPA, geothermal heat pumps can save homeowners 30 to 70 percent on heating and 20 to 50 percent on cooling costs over conventional systems. Average consensus is that it will take about 5-10 years to see a return in the investment but that utilizing geothermal energy could prove a good financial decision for the long-term homeowner. To encourage the switch to a renewable energy source, some utility companies and agencies may pay a rebate and energy Star-rated ground-source heat pumps may qualify for federal tax credit.

In the end, geothermal heat pumps are durable and require little maintenance. They have fewer mechanical problems and the underground piping used is often guaranteed to last 25 to 50 years. Quiet to operate and pollution free, geothermal heat pumps are an underused technology with a huge potential in the long run. Despite the debate on costs and the tough initial decision, figures indicate that 95% of heat pump owners would recommend a similar system to their friends or family.
