10​ ​Key​ ​Features​ ​of​ ​HVAC​ ​Systems It's​ ​probably​ ​not​ ​news​ ​to​ ​you​ ​that,​ ​while​ ​the​ ​first​ ​considerations​ ​when​ ​buying​ ​a​ ​new home​ ​are​ ​usually​ ​the​ ​plumbing​ ​fixtures,​ ​cabinets,​ ​countertops​ ​or​ ​floor​ ​treatments,​ ​the heating​ ​and​ ​cooling​ ​system​ ​is​ ​often​ ​the​ ​feature​ ​with​ ​which​ ​most​ ​people​ ​are​ ​dissatisfied after​ ​they've​ ​lived​ ​in​ ​the​ ​home​ ​for​ ​a​ ​while. The​ ​following​ ​is​ ​a​ ​checklist​ ​of​ ​the​ ​most​ ​important​ ​features​ ​of​ ​an​ ​HVAC​ ​system​ ​for​ ​a​ ​new home.​ ​If​ ​it​ ​saves​ ​you​ ​even​ ​one​ ​callback,​ ​it's​ ​be​ ​worth​ ​the​ ​time​ ​to​ ​read​ ​it​ ​and​ ​remember its​ ​points:

1. The​ ​design​ ​and​ ​type​ ​of​ ​ductwork.​​ ​If​ ​the​ ​ducts​ ​aren’t​ ​sized​ ​and​ ​balanced properly,​ ​the​ ​home​ ​will​ ​never​ ​be​ ​comfortable.​ ​Externally​ ​insulated​ ​round​ ​ducts are​ ​the​ ​most​ ​efficient;​ ​long​ ​runs​ ​of​ ​flexible​ ​duct​ ​are​ ​the​ ​worst. 2. The​ ​refrigerant.​​ ​Federal​ ​law​ ​requires​ ​R-22​ ​to​ ​be​ ​phased​ ​out​ ​in​ ​2015;​ ​what​ ​little that​ ​remains​ ​available​ ​for​ ​servicing​ ​after​ ​that​ ​will​ ​be​ ​very​ ​expensive.​ ​I recommend​ ​systems​ ​that​ ​use​ ​the​ ​environmentally​ ​friendly​ ​R-410A. 3. Balance​ ​dampers​ ​in​ ​the​ ​ductwork.​​ ​The​ ​worst​ ​and​ ​noisiest​ ​place​ ​to​ ​adjust the​ ​amount​ ​of​ ​heating​ ​and​ ​cooling​ ​coming​ ​into​ ​a​ ​room​ ​is​ ​at​ ​the​ ​diffuser​ ​grille. Balance​ ​dampers​ ​should​ ​be​ ​installed​ ​some​ ​distance​ ​from​ ​the​ ​diffusers​ ​and​ ​be balanced​ ​by​ ​a​ ​qualified​ ​technician​ ​with​ ​the​ ​proper​ ​tools. 4. Location​ ​of​ ​the​ ​indoor​ ​unit.​​ ​Attic-mounted​ ​furnaces​ ​will​ ​eventually​ ​leak​ ​and cause​ ​ceiling​ ​damage,​ ​unless​ ​you​ ​take​ ​special​ ​design​ ​precautions,​ ​such​ ​as​ ​a secondary​ ​condensate​ ​pan​ ​and​ ​drain​ ​line​ ​to​ ​the​ ​exterior.​ ​Furnaces​ ​mounted​ ​in closets​ ​at​ ​floor​ ​level​ ​are​ ​less​ ​prone​ ​to​ ​cause​ ​leaks​ ​and​ ​water​ ​damage,​ ​and​ ​they​ ​are much​ ​easier​ ​to​ ​service. 5. Location​ ​of​ ​the​ ​outdoor​ ​unit.​​ ​The​ ​worst​ ​places​ ​to​ ​locate​ ​outdoor (condensing)​ ​units​ ​are​ ​where​ ​they​ ​can​ ​be​ ​seen​ ​and​ ​heard,​ ​such​ ​as​ ​outside​ ​a bedroom​ ​window;​ ​where​ ​they​ ​can​ ​be​ ​easily​ ​damaged;​ ​or​ ​under​ ​the​ ​edge​ ​of​ ​an unguttered​ ​roof. 6. Efficiency.​​ ​As​ ​of​ ​January​ ​2006,​ ​the​ ​minimum​ ​allowable​ ​efficiency​ ​for​ ​new​ ​air conditioners​ ​will​ ​be​ ​13-SEER.​ ​(The​ ​minimum​ ​limit​ ​in​ ​2005​ ​is​ ​10-SEER.)​ ​Think​ ​of it​ ​as​ ​miles​ ​per​ ​gallon:​ ​the​ ​higher​ ​the​ ​SEER,​ ​the​ ​lower​ ​the​ ​utility​ ​bill.​ ​In​ ​fact,​ ​some air​ ​conditioners​ ​(those​ ​rated​ ​close​ ​to​ ​20-SEER)​ ​can​ ​cost​ ​half​ ​as​ ​much​ ​to​ ​run​ ​as those​ ​with​ ​the​ ​current​ ​minimum​ ​limits.

7. A​ ​filter​ ​dryer.​​ ​Installing​ ​a​ ​filter-dryer​ ​in​ ​an​ ​air-conditioner​ ​liquid​ ​line​ ​(the smaller​ ​one)​ ​always​ ​extends​ ​the​ ​compressor​ ​life​ ​by​ ​removing​ ​damaging​ ​moisture and​ ​any​ ​grit. 8. The​ ​condenser​ ​(outside)​ ​coil​ ​type.​​ ​Coils​ ​that​ ​are​ ​made​ ​of​ ​a​ ​single​ ​metal (such​ ​as​ ​aluminum​ ​coil​ ​and​ ​aluminum​ ​fins​ ​or​ ​a​ ​copper​ ​coil​ ​and​ ​copper​ ​fins)​ ​last longer​ ​and​ ​hold​ ​their​ ​efficiency​ ​better.​ ​This​ ​becomes​ ​especially​ ​critical​ ​in​ ​mildly corrosive​ ​environments;​ ​specially​ ​coated​ ​coils​ ​should​ ​be​ ​used​ ​where​ ​salt​ ​spray​ ​is encountered.

9. Return-air​ ​considerations.​​ ​Remember​ ​that​ ​in​ ​order​ ​for​ ​conditioned​ ​air​ ​to enter​ ​a​ ​room,​ ​an​ ​equal​ ​amount​ ​of​ ​air​ ​must​ ​be​ ​able​ ​to​ ​leave​ ​the​ ​room.​ ​Otherwise, there'd​ ​be​ ​no​ ​space​ ​for​ ​the​ ​conditioned​ ​air​ ​to​ ​occupy.​ ​The​ ​ideal​ ​condition​ ​here​ ​is for​ ​each​ ​room​ ​to​ ​have​ ​an​ ​entering-air​ ​diffuser​ ​and​ ​a​ ​return-air​ ​diffuser.​ ​However,

this​ ​extra​ ​expense​ ​can​ ​be​ ​eliminated​ ​if​ ​you​ ​add​ ​transfer​ ​grilles​ ​or​ ​jump​ ​ducts sized​ ​at​ ​300-400​ ​fpm. 10. Air-filter​ ​location.​​ ​Air​ ​filters​ ​should​ ​be​ ​located​ ​where​ ​they​ ​are​ ​easy​ ​for​ ​the homeowner​ ​to​ ​reach.​ ​Since​ ​the​ ​filters​ ​should​ ​be​ ​replaced​ ​about​ ​every​ ​three​ ​to four​ ​months,​ ​the​ ​homeowner​ ​should​ ​be​ ​able​ ​to​ ​find​ ​the​ ​location​ ​and​ ​replace​ ​the filter​ ​with​ ​minimum​ ​effort​ ​and​ ​searching.
