We have typical builder-type of AC units on our Summerlin (Las Vegas) home. I've been told by a reliable source that they are around 9.0 SEER. Our summer electrical bills are in the low $700 range per month, or about $500 for AC after factoring out the pool pumps and domestic consumption. The two units are in their 6th summer.
An HVAC contractor tells me that we can save substantial power dollars by switching out the outside units and the inside coils to Rheem 13 or 14 SEER units. He said that RHEEM is probably the most "basic" of the newer systems, still uses R22 for lower head pressures and has more generic low tech parts than other systems. He said that it was what he put in his own home. The difference between the 13 and
14 SEER units is the air handler, which he said he might or might not be able to use until he does a static air test on it to see if the blower and ducts are sufficient.I guess my first question is whether RHEEM is decent, basic equipment. If not, what brand is recommended?
The contractor also looked at the diffusers in our ceiling and told me that I should change them out with ones that offered low restriction. He said I should do this myself. Is this correct to get a more efficient system?
Nobody.
