I'm a home inspector with some HVAC experience. Inspected a new house with what appears to have mis-matched condensor and evaporator coils. Concensor is Model # 13ACD-036-230-01 Evaporator is Model # C33-43C-2F-2. Looks like I might have a 3 ton mixed with a 3.5 ton? Can you tell me if this is a problem?
Thanks Inspector Vern
I did not look it up, however it is common to match a condenser with a half ton larger evaporator. There ought to be a code that the refrigerant control type (I.E., TXV or fixed orifice & number of the orifice, etc.) be listed where it is in plain view.

It's common to mismatch a coil for better humdity removal. I've heard it both ways, some folks say to use a larger coil for greater surface area. Ohters say to use a smaller coil cause it will get colder.
Both "great taste" and "less filling" camps are trying to reduce humidity. In any case, it should run great, if the suction line is beer can cold.
Ah yes, beer can cold. The hack standard, which is the one thing you're good at.
What kind of HVAC experience do you have?
hi chris, using sweatback as a gauge is completely irresponsible as a tech, and is doing a gross disservice to your customer. theres no faster way to flood a compressor than using sweatback.
Ha! In some parts of the country, liability insurance has gone thru the roof for the home inspection industry. I hear some states require licensing, liability insurance, workers comp etc
udarrell may indeed be correct, but you said it's a new house, which could mean 13 seer, which means ARI matched systems.
A smart home inspector who knew he was out of his element would probably defer to a local hvac professional for his opinion.
How leaky is the duct system? You did do a pressure test on it didnt you? If not, you better advise your client of a potential 25-35% duct loss, resulting in higher operational costs.
I wonder, do your customers get what they pay for?
Soooooooooooo, you're an inspector who doesnt know your job and you came in here to get a final answer so you can harass some poor homeowner/builder? Do your freakin job and call the manufacturer or look it up online. Preferably get it in writing. You have no idea who you are getting an answer from in here. Especially me. I might tell you its wrong and you need a 10 ton evap coil to get the proper match. Then on the other hand, you might get Stormy who tells you you need to add a water heater and a lock to get the proper match. Now go do your homework the right way. Bubba
Beer can cold is one of the jokes that's been on this usenet list for many years. Seemed like a good time to include it in one of my emails. As you say, there are other charging methods which are much more accurate.
My experience is limited, hence the request for opinions from the gallery. I obtained a universal CFC certificate and a journeyman license in 1996. Worked as a service tech for a local Train contractor for a little over
18months. Discovered the HVAC industry had shot itself in the foot by under bidding each other, forcing the use of unskilled labor and shoddy work. Net result was HVAC labor/knowledge was less valuable than other fields intelligent enough to control there market. " Electricians, Plumbers, Communications"I left the field in pursuit of a more gratifying carrier. As a licensed home inspector I am hired by the customer as a "Generalist" and by a visual inspection, report on any systems or components that do not function as intended or adversely affects the habitability of the dwelling; or warrants further investigation by a specialist or requires subsequent observation. Note visual, not technically exhaustive, inspection. It would not be responsible of me to require a specialist without justification. "None of you work for free".
When there is any question, I feel responsible to research all available resources and render a decision on the action my client should take. While this forum was not the only source I used for my decision, it did have thoughtful moments, and I would like to thank those of you who were willing to help. I discarded information I felt came from the unfounded arrogance of a hill ape named "Bubba" who's referral business has provided ample time to monitor and respond to any and all post.
Nothing is FREE. Matching indoor and outdoor coils will provide the system with the most efficient balance. Any deviation will starve or flood the evaporator and reduce efficiency. The fact that a lot of contractors are doing this "right or wrong" has restrained me from recommending further investigation by a specialist at an additional expense to my client.
Right-on, gofish. You hit the nail squarely on the head. There are a lot of systems that have numerous energy wasting problems that are never remedied.

That would be a definite maybe
Too bad this "hill ape" knows the answer and you and your more gratifying career are completely and "udderly" clueless. Two VERY quick ways to find out if you have matching coil/system. Too bad you aren't a "hill ape". Maybe then you would have a f****ng clue how to do it and not have to come in here to ask. By the way, a home inspector is about one step below a "yard ape". Bubba
Hats off!! Bubba scores two points!! You go Bubba!!! :))
