Is It a Good Idea to Cover Up Your Outdoor Air Conditioning Unit (compressor) with a Plastic Tarp fo

sure I would think it would protect the components in side

1. My central air conditioning unit isn't working. How can I get it to work?

You need to give much more detail to get a helpful answear to this question. Try to describe just what is going on and what you have or have not tried

2. what is the cause of bad smell on home air conditioning unit like split type?

The unit probably needs cleaned. The condensate drain pan can get some stuff growin in it and the coil probably needs cleaned. The whole system requires some routine maintenance. For more info, check out the ductless ac page at www. hvac-for-beginners. com.

3. What type of regular maintenance should I be doing on my central air conditioning unit?

Check/Clean/ Change filters or Electronic air cleaner, inspect blower motor wheel for cleanliness and alignment, check capacitors capacitance, check evap coil cleanliness and ability to transfer heat(delta tees), check filter driers inlet outlet temps, anything above 3 degrees is a restriction/moisture, condenser coil cleanliness and ability to transfer heat. 10 degree delta tees are acceptable. Generally not performing annual maintenance will also void manufacturers warranties or labor warranties. Two schools of thought on checking refrigerant levels are it should be checked annually to see if there is a leak that's formed or you should not because every time you gauge up you are removing charge from system. With new low loss hoses and ball valve hoses refrigerant loss is kept to a minimum so it's less of a concern. Then again if you just put a system in a year ago and you are just doing basic check-up, getting involved is not necessary. A good tech will be able to know when he/she should be gauging up based on the temperature readings they get while checking the indoor unit, after letting the system run for 15 min, which is usually done while performing the AHU maintenance

4. Outside residentual air conditioning unit has huge block of ice.... in 80 degree weather.?

Yes, turn the unit off until it has completely thawed out to prevent permanent damage. The coil inside the furnace unit is likely "frozen up" as well and could take several hours to completely thaw. Once thawed... the system may work until it starts to freeze up again, but likely wo not cool like it should until properly charged. Minimize use and closely monitor until repairman can take a look. Could be other things, but does sound like low freon in the system. A quick check with gages by a A/C pro will determine.

5. I WAS TOLD I NEED TO REPLACE MY COMPRESSOR UNIT ON MY WHOLE HOUSE AIR CONDITIONING UNIT BY YEARS END?

Hi, yes there is a phase out of R22 by the end of this year, but initially stop producing of virgin refrigerant, but you can still use recycled R22 up to 2015, but the european government are looking to bring this date forward. but this might not concern you as your unit might not be using R22, you need to find out what refrigerant your system is operating on and post it, all system now can be retrofitted using new more friendly refrigerants but all HCFC refrigerants are to be phased out within the next ten years but by this time arrives your A/C unit will be past it life expectancy. Your unit can probably be retrofitted to a different refrigerant and oil compatibility is no longer an issue as the old mith you cannot mix them is long gone as they now tell you to mix them in some retrofits. Just be careful as engineers will try and replace your unit because they will get a new install out of it and perhaps do not have the experience with the retrofitting process. Regards

6. What is better, an r22 Air conditioning unit or a r410?

when did the r410 come out about what year ??

7. where can i find info. on my air conditioning unit?

i dont know but thanks for hte two points just playing go to google duh

8. If I am replacing my central heat and air conditioning unit, is it cheaper to stay with the same brand...?

Unless you have a special situation, it wo not make a difference. They all hook up the same way. Check the efficiency rating vs cost. If your central unit is right outside a bedroom window, or above a living area, you want to find a quiet one. Get estimates from independent and branded companies.
