Say my A/C goes out.I call a servise tech..he says i need a new condesing unit.Would 13 seer affect the inside

Question

I mean the inside isnt broke....would that have to be replaced also??and what if i dont want to spend the EXTRA money for it to be replaced??......and he just replaces the outside unit...that would okay right?

errrr...service tech

errr condensing unit

Answer 1

no seer is the energy effeciency rating

a 13 will do the same job as a 10, but the 10 uses more juice

tons is tons, btu's is btu's

Answer 2

I felt I had to answer. Your outside unit can be replaced with a 13 SEER with no problem. SEER is an energy rating for the unit outside. These units 10, 12, 13 etc. use R-22 or R134A usually, ignore the R-12 answer. Your tech can replace the outside unit only if it matches the size of your inside coil (i.e 2 Ton, 3 Ton, 5 Ton unit) this is the size to keep all these refrigerants operating properly in the internal operations of things.
So, to answer your unit question, yes, the outside only would be permissible if the same ton size matches your coil; otherwise you will replace both. Your previous unit outside broke for a reason..usually moisture in the refrigerant does that, after the old refrigerants are evacuated have your tech put in a "line filter" while installing the new unit. It'll save you future headaches and keep the system's refrigerants clean of moisture.

If you have a separate unit for heating and cooling, you can replace one or the other, however if you have a heat pump, it is best to replace both.

I would suggest that you replace the AC coil and the feeder lines too, if the unit is very old, as they can be corroded.

If both your heating and AC units are old 10+ years, I would suggest you replace both, as there are efficiency gains Worth the cost.

I myself purchased a dual stage unit, that will heat at half of the total BTU if the temperature isn't too cold. For my money, I'd suggest you stay with a single stage.

Also, the government will only allow 14 SEER units to be manufactured now. I would put a 13 SEER on a rental because of price, but I put a 14 SEER on my house just last year.

They make 16 SEER units, but they are not a true 16 SEER unit. The efficiency comes from running only part of the coil when the temperature isn't as hot. The trouble is they cost considerably more for the efficiency gain.

Answer 4

The A-Coil needs to be matched to the Condenser in order to provide optimum performance.

Our benevolent federal government has made it impossible for us to make repairs to our existing systems. Much like the government outlawing toilets that use more than 1.6 gallons of water the government has gotten involved in our air conditioning too.

The new systems are much larger and use a different refrigerant than the old systems. Because the new refrigerant is less efficient they have to use larger system components.

Your old A-coil is designed for an R-12 system and probably for a lower seer or efficiency rating. The new products require that the refrigerant be cycled more to accommodate for it's lack of efficiency. As R-12 will be eventually banned altogether you will not be able to repair that system so you will be forced to replace it.

If your tech. tells you you will need a need a new A-Coil they probably know what they are talking about.

For this idiocy you can thank Al Gore and the other waco's that believe refrigerant is causing Global. warming.

The truth is the patent had run out on certain types pf refrigerant so the chemical industry paid huge sums of money to people like Al Gore to foster this ridiculous notion that refrigerant had some effect on climate.

The reason for the fraud was that in the 1970's, DuPont's patent for CFC was running out and not renewable. To prevent anyone else from producing the highly profitable CFC's, DuPont created the Montreal Protocol myth, which banned all CFC manufacture and use, and only allowed the future use of DuPont's newly patented HCFC replacement. This would again leave DuPont with a monopolistic control of the world supply of freon refrigerants.

The HCFC products are not as efficient as the original CFC products. But we are forced to use them anyway.
That is the real inconvenient truth!

Answer 5

Your equipment will not be compatible with each other, if you just replace the condensing unit. Bottom line you will need to replace both your Condensing Unit and Evaporator Coil. Make sure they replace the Drier on the system. Confirm your manufacturer and labor warranty with the contractor and change your air filter every 30 days.

Your going to have to spend the money on the repair. I don't believe that the service tech is trying to sale you something you don't need, you need it, that is what he's telling you. It's not extra money!!

Answer 6

I had that done a few years ago - replaced the outside unit but kept using the inside unit (over 20 years old). Didn't have any more problems. Sold the house after a year.

Answer 7

I propose, i'm no longer able to truly say lots different than it incredibly sucks. The IRS has to try this simply by fact in the event that they do no longer, they might get criticized and in all risk sued for discrimination applications. they must handle human beings as equals. That being suggested, the Yankees or Derek Jeter ought to cover the fees of that. I5 might purely be approximately $20,000 and to DJ/the Yankees, it particularly is not something. although, if every person catches a house run ball and is presented a team of stuff, be certain you contain on your demands that the gang will pay the taxes.

Answer 8

You shouldn't have to replace the inside part, just the affected part.
