can breathing freon from a leak in indoor ac coils cause health issues? in a condo, have an outside ac unit with 'air handler' in my laundry room, with coils I assume freon runs thru from outside (they get cold). Had the fan motor replaced and the tech had to add a pound of freon, commented could be a leak in the "inside coils" and may need to add more freon in a couple of years. Didn't think anything of it at the time, but have allergies, and my congestion is worse now the ac is back on than during the 3 weeks when I had the windows open with fans, and that doesn't make sense. Wondered if I'm breathing freon, and that could be the issue?Technician says there is a leak in the evaporator coils indoors. Air is pushed through the cooling coils and into the living space of the home. We breath that r-410a coolant. The manufactured evaporator coil is 2 years old. We have spent over $1400 repairing low coolant problems without replacing the evaporator coils. We now see that is the problem that needs replacing.

Here is a link to an MSDS for it - you can read for yourself on the toxicity and side effects. Basically, has not been found to be toxic or cancer causing, but breathing it can cause a number of effects as is says under the Inhalation item, and when it contacts heated surfaces like a furnace or water heater flame is can for acids. It also carries a lubricant with it in the air conditioning system (commonly mineral oil) and vaporized oils are known to be a significant respiratory hazard, both chemically and because the aerosolized oil coats the lungs causing edema and gradual suffocation.

/_Uploads/dbsAtt...======However, if leaking a pound every yesar or few, unlikely to have a noticeable effect unless you are breathing right at the leak point. I would say more likely, the respiratory effects are from inadequate filtration of dust and lint that is being recirulated in your home, or from mildew/mold growth on the evaporator coils. That is a common source of respiratory issues, as is forced air ventilation in general because it tends to pull inand recirculate more allergens from outside and inside than direct electric or steam/hot water radiator or baseboard systems. No it can not hurt you at all. The only way refrigerent can harm you is by inhaling it directly into the lungs, which can cause frostbite and kill you. The only thing its hurting is your wallet and the ozone layer.The only way its harmful is by burning the freon directly with a flame. A furnace is not hot enough to burn leaking freon. Phosgene gas is produced when freon is burned. It will turn a yellow torch flame green during that process which I have seen many times before.

If you breath in the fumes from the green flames "Phosgene gas" it can kill you instantly. Phosgene gas is also found in Mustard Gas which has been used as a chemical weapon since WW1.There is no way for a homeowner to come in contact with Phosgene gas unless the furnace or house is on fire and you are standing at or above the evap. coil at the very second the coil begins to melt releasing the gas. If you are not there right at that second trying to inhale the stuff it just gets burned up by the rest of the fire/flames.Freon is 100% safe to homeowners. Source: 15 yrs exp.

Oil leakage observed at AC coolant line at bonnet -- too cold to run unit Need a home inspection in Hawaii? listing of Hawaii certified home inspectors. Re: Oil leakage observed at AC coolant line at bonnet -- too cold to run unit Frank I would like to help you get your terminology going in the right direction I don't understand what you are calling a bonnet in the pic I see the suction and liquid refrigerant lines entering and exiting the A-coil plenum box. And to answer your question yes if there is refrigerant oil dripping from the line set which also means that refrigerant is also leaking from the system and the unit would not function properly. The remaining refrigerant if any would be required to be pumped down and retained in the exterior condensing unit. The leak on the suction line repaired, a vacuum pulled on the line set and the A-coil and the system re-charged with refrigerant.

In Oklahoma that would be approximately $350.00 repair job. Ca about $650, If a NY engineer repaired the leak cost would be about $850.00 Try a little more explanation with clients. We were unable to inspect the cooling system due to the cool 50 degree outside air temperature (industry standards state operating an A/C unit below 60 degrees can potentially　damage　a compressor). We also noted the unit was approximately 23-24 Years old +/-. Units like this typically have a normal life-span of 8-15 years. We also noted an oil like substance on the freon lines (possible sign of past or present freon leakage). We recommend having a licensed and competent HVAC contractor service the unit, leak check coils, check freon levels, and the proper operation of the unit prior to close.
