Local Questions, Straight Answers
Anything different about installs in the Asheville area specifically?
Three things bite newcomers: elevation (a spec that works downtown fails at 4,000 ft — check heat pump capacity tables against real design temps), propane prevalence outside the gas grid (carry conversion kits), and vented crawlspaces that condense on everything all summer (R8 duct, sealed drains, float switches). Local experience is mostly knowing those three.
Do heat pumps up here need snow stands?
Above the valley floor, yes — mount the outdoor unit high enough that defrost meltwater and drifted snow don't refreeze into the base pan. Wall brackets or a proper stand beat a pad in any spot that holds snow. It's a cheap line item that prevents February coil damage.
Does crawlspace encapsulation change the HVAC spec?
Meaningfully. A sealed, conditioned crawl pulls duct into the envelope — condensation risk drops, R-requirements ease, and the system may need a small supply into the crawl per code. If the encapsulation crew got there before you, re-look at the duct plan instead of copying the old one.
Propane furnace runs weak at a mountain cabin — altitude thing?
Could be. Gas appliances derate with altitude — manufacturers spec it, commonly around 4% per 1,000 ft above a threshold — and some equipment wants a high-altitude kit or pressure adjustment. A 4,500-ft cabin isn't Denver, but it's not sea level either. Check the manual's altitude section before condemning the unit.
