Air Handler mismatch with compressor I have a situation where the air handler is 5 ton and the compressor is 3.5 ton (both 2009 models) The HVAC guy says that this was done in order to meet the SEER requirements or something to that effect..... Does this make sense? Can the system be really more efficient under this scenario? Thanks for you input! Need a home inspection in Nevada? listing of Nevada certified home inspectors.

Re: Air Handler mismatch with compressorThis is how you obtain a higher SEER rating. The air handler will be oversized to meet the SEER rating. rooftop ac unit troubleshootingAnd yes it will be more efficient.air conditioning units for vw transporter Why did you not believe the AC contractor?cost of freon for ac units Originally Posted by rmurphy1 I smell smoke when you say ahu does that mean refrigerant coil or blower or both. Standard protocol worst case is to never mismatch more than 1/2 ton over or under between the compressor and the refrigerant coil The CFM of the blower is also calculated to match As the Master HVAC Mechanic (retired) states - Protocols are such that the mismatch shouldn't be more than 1/2 ton...

Why didn't I believe the HVAC contractor? Because I have known them to be wrong and the above stated protocols have been in our toolbox. I haven't disagreed with the man, I am merely finding out if what he is saying is correct. If the systems are so much more efficient this way - Why aren't all systems installed in such a manner? I am NOT an HVAC professional. I am trying to improve my knowledge base here. Is it not right to call out the mismatch and refer it to a professional? Sure if you want to use engineering formulas like this oneThe polynomial equation that shall be used to represent the tabular data is a third degree equation of ten coefficients in the form of: X = C1 +C2 � (S) + C3 � D +C4 � (S2 ) + C5 � (S�D) + C6 � (D2 ) + C7 � (S3 ) + C8 � (D�S2 ) +C9 � (S�D2 ) + C10 � (D3 C = Equation coefficient, represents compressor performance S = Suction dew point temperature, F [C] D = Discharge dew point temperature, F [C]

Originally Posted by wsiegel Back in the late 70's and early 80's that's how Coleman was achieving their high SEER rating. They were selling them as a package deal. We installed a lot of 3 ton condensing units matched with 5 ton A coils plus a liquid line shut off solenoid valve and an indoor blower time delay relay in those days. I had one in my own house until 3 or 4 years ago. As I recall the SEER was 12.4 or so then. Of course you can't (shouldn't) go the other way and use a smaller A coil. Originally Posted by sparksnmore We installed a lot of 3 ton condensing units matched with 5 ton A coils What was the sweat line on the coil I have a hard time believing that a 3 ton condensing unit can hold enough liquid in its condenser to prevent a 5 ton coil from being starved. I was taught in two different A/C schools that you never over size the A-coil by more than 1/2 ton. To be honest I have never seen a MFG increase the size of the indoor coil to achieve a higher Seer rating but I am not a mechanical Engineer either.

My observation has always been to increase the size of the outdoor condenser on the high seer units. Carrier was very famous for this when seer rating became a issue. They increased the size of the outdoor condenser X3 over a standard 12 seer unit, and had this little compressor wrapped in a blanket could barely see it. BTW Trane also did the same thing monster condensing unit same size coil Air Handlers and coils Installing the correct air handler and evaporator coil is essential for getting the highest level of comfort from your central air conditioning or heat pump system. Make sure that your system is performing to its optimum level with our air handlers and evaporator coils.
