This offers a platform for business to publish their own reviews and individuals to hastily post reviews without the business in question's ability to expertly deal with the issue. Furthermore, no business would offer a negative referral; just those that are exceptionally positive. None of these are ideal dynamics for consumers seeking entirely unbiased reviews and referrals.

Frequently Asked Questions:

Why Does My Air Conditioning Keep Freezing?
I Have A 3Ton Air Conditioner With A 5 Bed Room House. I Have With 6 Air Vents. Everytime I Put It Below 75Degrees It Freezes Up How Come. Last Time Someone Came Out About 3Months Ago They Put Free-On And Said It Was Already Full. So What Else Could Be Causing This To Happen. I Keep Getting The Run Around People Not Really Knowing Whats Causing The Problem. I Have A Wood Roof And The Air Ducks Are In The Addict. Its Averages 90+Degrees Where Im At During The Day.

For a 3 ton system, your indoor blower should be moving approximately 1200 cubic feet per minute across the evaporator coil (indoor coil). As long as you have sufficient air moving the number of vents is immaterial. The most likely cause of the freezing is a dirty air filter. The dirty air filter reduces the amount of air that can move through the system. That results in less heat reaching the coil and the pressure remaining too low. The boiling point of the refrigerant will then be lower as well. If the boiling point is below the freezing point of water, then humidity in the air will freeze on the coil. Another possibility is a restriction in the system reducing the flow of refrigerant to the evaporator. A partially plugged liquid line filter drier can produce that situation. If you can feel a temperature difference on the liquid line filter drier's inlet and outlet, then it is becoming plugged and will need to be replaced. Moisture in the refrigerant system can also cause this condition. If moisture has been introduced, it will freeze in the metering device and restrict the flow. A kinked liquid line can also produce the low flow condition. That can happen if someone has inadvertently stepped on the refrigerant lines. Either a reduced amount of air across the coil or a restricted flow rate for the refrigerant can be responsible. There are ways to determine how much air is moving and whether the charge is correct, but it will take a qualified hvac service technician to check them. I'm afraid you'll have to find a better technician. Any technician that automatically decides you're low on refrigerant isn't taking the time to properly diagnose the situation. Ask for a well experienced technician or for the service manager to come out and check your system out. Hope this helps

Which Is Better For Air Conditions-- Fuji Or Panasonic?

I like Fuji(apples, and water lol)

I work for fry's electronics and Panasonic was the brand that never came back. They only came back because it got to cold.

Fuji prices are about the same as panasonic's but the energy rating was higher on the Fuji's so they will be alittle more costly to use.

Why In Certain Conditions De-Icing Systems Will Not Be Right Thing To Do And One Has To Refer To Anti-Icing?

Generally speaking there are two main systems used to prevent/remove ice from aircraft wing leading edges.

1.- Anti-icing - Uses bleed air extracted from the engines. The bleed air is ducted from the engine through the wing anti ice valves into piccolo tubes that run in the wing leading edges. The hot air heats the leading edge preventing ice from forming. Hence the term 'anti-ice'

2.- De-icing - Uses a mechanical device (usually inflatable rubber boots) on the leading edge of the wings to break off the ice AFTER it forms on the wing. Hence the term 'de-ice'.

De-icing systems are usually used on smaller aircraft that have a limited supply of bleed air. Smaller business jets, turboprops and some reciprocating engine aircraft usually have de-icing systems.
The bigger jets that have sufficient bleed air to literally blow it away use anti-ice systems.

So in summary the main condition in which you would use de-icing is if you have a limited supply of bleed air from the engines.

Car Air Conditioning?
I Am Told That The Air Conditioning In My '92 Subaru Legacy Works But It Needs To Be ' Hooked Up'. How/Where Do I Do That? Help Plz. Thanks!

It sounds like it doesn't work. Who would "unhook" a working air conditioner? Have it tested at an auto a/c shop, it may need just a belt, it may need a recharge, it may need all kinds of things. It likely has R-12, which can no longer be purchased from anybody except a licenced fitter in possession of recycled freon. It is expensive. You could be looking at a retrofit for R-134. In any case, do not fart around with it yourself.

Which Is Cheaper On Electricity?
My Boyfriend And I Just Bought Our First Home, Prior To This We Have Been Living In Apartments, And The Most Recent One Had A Problem With The Electric Company, So Every Single Month We Only Paid $8.11. (The Meter Reader Apparently Read The Wrong Meter Every Month, We Called Customer Service Many Times About It Because We Didn't Want To Get Hit With Back Pay Later On Down The Road, And Every Time They Said It Was Right.) So At The End Of This Month Is When We Get Our First Taste Of Real Electric Usage In A Home. The Person We Bought It From Said The Maximum She Had Ever Paid Was About $160 In A Month. We Have Been Trying To Save On Power By Cutting Off All Lights When We're Not Home, Even When We Are Home In The Day Time I Just Open The Curtains, We Minimize Tv Watching, We've Even Been Unplugging The Computer When We're Not On It And Unplugging The Microwave And Other Things To Cut Down On Hidden Electricity Usage. My Question Is This...Is It More Cost Effective To Have Air Conditioner Running Or To Use The Ceiling Fans? It's Cool Enough With The Ceiling Fans On, So I've Just Been Running Those But I Wanted To Know If It Saved On Electricity Or Not. Thanks! Any Other Electricity Saving Tips Would Be Appreciated As Well.

Air conditioning unit is the most expensive electrical appliance in the house.. followed by electric dryer, then your hot water heater and then the condenser on your refrigerator and/or freezer. Turning off the A/C and using a fan will save you considerably. Hang clothes outside and/or remove clothes from dyer early and let finsh in closet or outdoors. Limiting the amount of items in your fridge/freezer and the number of times you open and/or close your fridge will save units used. Cut shower times in half. Wash clothes in cold water. Hang clothes outside (if using electric dryer). TVs, Computers, Clocks, Cordless Phones use minimal electricity.
