Good point. Mom's is having that same issue in her current kitchen and hallways, which we converted to CFL's a year or two ago. My kitchen is the same. Will definitely get fully sealed cans in mom's new house (even though LEDs don't have that issue with not hitting full brightness immediately).Our place was built in late 1999, and has insulation contact rated cans from that era with blown-in insulation in the ceiling space covering the cans. Since we went to CFL bulbs in the kitchen, the warm up time before they hit full brightness in the winter is significantly noticeable. So in spite of having attic insulation, there is still enough cold air reaching the CFL's to affect their performance when first switched on.
I bet her energy bill will be cut at least in half compared to her current 3600 sq. ft. built in 1986.
Btw, this is the heat pump we're going with: (same as Trane XL15i)
Gold XI Heat Pump - Heat Pumps - Heritage® 15 Heat Pump -American Standard Air Heating and Air Conditioning
And the air handler: (same as Trane Hyperion XL)
Platinum XV Air Handler - Air Handlers - 4TEE Variable-Speed Air Handler - American Standard Air Heating and Air Conditioning
And air filtration unit:
Whole Home Air Filtration | Get AccuClean Air Filtration System | American Standard
The reason we're going with the American Standard branding is that the builder has access to that model line, but not the Trane one. Go figure.
Also, I picked the XL15i as opposed to the XL16i (2 stage heat pump) after doing a lot of reading over on the hvac-talk forum. They rate the Trane's in the following order: XL20i, XL15i, XL15, XL16i. While the XL16i is dual stage, the first stage uses between 70-80% of the energy of the 2nd stage. You have to step up to the XL20i, which has 2 compressors, to realize stage 1 only using 50% of the energy of stage 2.
Given that the size of the units in mom's house are 2.5ton / 30,000 BTU and rated at 16.5 SEER, the roi just wasn't there to step up to the XL20i @ 20 SEER. The air handler will have 2 stage back-up heat (5kw + 5kw).
I'm going to pick up a wifi thermostat to control the system. Looking at the 2nd generation Nest and others. I need to make sure it will work correctly with the variable speed blower in the air handler.
