Tip & How-To about Heating & Cooling

How to substanjully lower your air conditioning bill in 10 minutes

This tip will not only drastically lower your A/C electric bill it will increase the life of your system. This is 75% of what you pay an A/C tech. to do when you have them out for your annual service. I have over 25 yrs. in the H.V.A.C. industry and this is an insider secret!! #1turn off the system at the thermostat. #2 go out to the condensing unit on the outside. #3 (important) unplug the power disconnect hanging on the wall next to the unit, lift the lid on the small grey box and pull out the the fuses. set them aside. #4 get a water hose and a good spray nozzel and start from the top of the coils and work your way down. The more pressure the better, you should be able to see the water coming through to the inside of the coils when you look through the top. Take your time and really blow that dirt out, you'll really be suprised how dirty they are!! #5 let unit drain for about 15 min. then plug power disconnect back in and enjoy. EXTRA TIP.. I find prespraying with simple green really makes a big differance.

I have a Troy Built GVC 160 (2600 psi) pressure washer. I used yesterday afternoon without problem. Today, I can get it started, but it conks out immediately as soon as I engage the wand. I'd appreciate any help you can provide.


Make sure that the engine is set to full power. Lower the pressure to the unit with the pressure adjust knob as much as possible. Check the nozzle to make sure that no debris has entered and is lodged at the tip of the wand. Start the engine with the spray gun handle in the open /on position allowing water to flow thru. Allow the engine to run for a while to warm-up. Increase the pressure a small amount at a time to reach the desired pressure. To increase the life of the unit, do not use the machine at max. pressure setting. Adjust to about 75% of rated capacity and increase only for stubborn debris then reduce. Good luck

I have never used central ac before - how do I set it? If it is on 75 will that cool the house? If I want it cooler, do I put it lower? like 65?


As to your question 'will 75 cool the house?' The answer is 'yes' - if the outside temperature is low enough. Typically speaking you can expect your central AC to cool a properly insulated house to a down to a temperature of about 20-25 degrees lower than the outside temperature. For example - if the outside temp is 95 degrees. You could expect to get your house down to 70-75 degrees. If the outside temp is 110 degrees then you could only expect to get the house to 85 or 90 degrees.

So .. as you can see - your 'inside' temp will be directly affected by the 'outside' temperature.

As to the operation of central air; it is very simple.

I would suggest that you not pay 'too much attention' to what you have the thermostat set on. A comfortable temperature - is a personal thing - so - I would set it somewhere - say 72 and see how I (and others in the house) was handling that setting.

If you want it 'cooler' just 'notch' it down a degree or two - if you need it a little warmer - turn it up a degree or two. Do this "fine adjusting" till you have the temperature setting you are comfortable with.

Usually the more you can leave your thermostat alone the better off you will be from a comfort position and an electrical useage standpoint. Obviously, the higher you have your thermostat set the 'less' it will cost you on your electric bill.

How high you set the temperature is a balance you have to come to based on how comfortable you want to be - matched with how much you want to hold down the electric bill.

hope this helps

Yes. The use of dimmers can reduce the use of electricity and, thereby, save money and help conserve the environment. Dimmer use can also increase the life of the lamps (light bulbs) being controlled.
