not sure but think I may have been taken advantage of(or thought they did)

[Guest guest]

Talked to one person and they said they never heard of To Much Freeon

in heat pump. Wondering if I was set up for it to be too High and need

more later cuz too low. Yikes. Anybody know abount Freeon sp??

amounts? I know it can be low but too High??? Now I'm wondering

about the other things he did. He was only here to install my water

filter to the whole house. I'm not going to let him intall the water

filter system or anything else.

Rhonda,

I agree fully with your decision that if you aren't sure, don't do

it. Get better information that you can understand and trust. THEN

you can make better choices.

As for freon, it won't be too much or too little Quantity, but

pressure. Is the pressure too low or too high? The rest is beyond my

expertise but I suggest you get another opinion from an A/C

contractor. Also, they don't use Freon anymore but another chemical

that I can't remember. I'll find out these details.

In the meantime, anybody know the answers?

I REMEMBER MY BROTHER PUTTING SOME IN MY AC SYSTEM IN MY CAR. IT ONLY

HOLDS SO MUCH. I HAD A TINY LEAK SO AFTER AWHILE IT QUIT COOLING

AGAIN. BUT AS I UNSTAND YOU CAN ONLY FILL SO MUCH AND IT WONT TAKE

ANY MORE. I'VE NEVER HEARD OF IT BEING TO HIGH EITHER.

Rhonda,

I checked with an expert I know and he said a unit can be what he

called " overcharged. " However, this is usually a misdiagnosis for

dirty cooling coils - which I doubt in your case because the unit is

so new - and is also a frequent scare technique.

He may be right but the way you describe his recommendations he

sounds " sales happy. " I'd get a second opinion before spending any

money.

Rhonda,

The appropriate methodology for determining proper refrigerant charge

in this type of unitary HVAC equipment is by measuring superheat (non

TXV), subcooling (TXV) systems or by weighing in the refrigerant

charge. In addition, equipment that is not properly evacuated and

dehydrated below 500 microns before charging with refrigerant can

perform poorly even if the charge installed is reasonably accurate.

This is because non condensables will be present in the refrigerant

oil. This is particulary a concern on todays high efficiency R-410A

systems because of the POE oil that is used. Whether R-12, R-22, R-

410A, R-134A, R-502, etc. the equipment can indeed be overcharged,

undercharged or of course properly charged each will impact

performance. Each will also indicate a variety of different conditions

each of which can be confused with others if the condition of the

refrigerant is unknown. This is why untrained people should not touch

refrigerant based systems. I would suggest that you try to find a North

American Technician Excellence (NATE) Certified Professional who has

Heat Pump Service credentials. You can visit www.natex.org to search.

You should also ask them if they or their company is an active member

of the Air Conditioning Contractors of America and if they are members

of the Refrigeration Service Engineers Society. If not at least one or

more of these I would keep looking until you find someone who is.

Expect to pay more for the services of these professionals, but you

will get a quality service. I can assist you in finding someone if you

need assistance, please feel free to contact me off line.

Also, to service units with refrigerant such as R-22 or R-410A which

are commonly used in residential unitary equipment one must hold a Type

II or Universal Certification under 40 CFR Section 608. If someone was

blowing off a charge then that is a violation of the Clean Air Act. It

is more likely what you viewed (if a brief release) was a deminimis

release from disconnecting the hoses. If it was a sustained released

and intentional then that is a problem.

One other comment worth making regarding filtration, each manufacturer

has a fan curve associated with their equipment that needs to be

checked and followed. Please do not assume the new equipment can handle

the higher MERV filtration available. Filtration added to the system

needs to be considered in addition to ductwork, (wet) coils, heat

exchangers, etc. to determine if adequate air flow can be obtained and

the equipment can still perform within its prescribed temperature

limits for both heating and cooling as well as within the prescribed

motor performance ratings.

There is so much more to HVAC and it takes someone with appropriate

knowledge and expertise to do the work correctly today. The equipment

is more sophisticated, pressures and temperatures are more critical and

in many cases less forgiving and with the focus on energy and

environmental conditions such as it is we should be taking every

opportunity to fix not only HVAC equipment but the building it is

installed in to prevent other unintended consequences that can be

impacted by improperly installed or serviced HVAC.

Good luck.
