Somerset County, MD Insulation Payback
Somerset County attic insulation, by the numbers
Somerset County sits in IECC climate zone 4 (Mixed-Humid) — heating load in winter and cooling load in summer, both worth taking seriously here. For a currently uninsulated attic, DOE and ENERGY STAR recommend building up to R-60. Going from R-2 to the recommended R-60 costs roughly $3,480 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 2.7 years at an estimated $1,276/year saved. Topping up the attic pays for itself fast here.
Heating vs. cooling in Somerset County
Split it out and it's roughly $1,058 a year on the heating side, $218 on cooling. By estimated insulation savings, Somerset County lands in the 37th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Somerset County comes in 628th by savings. Maryland averages $1,395/year across the counties tracked here; Somerset County comes in 9% lower.
Somerset County's actual weather, not a national average
NOAA's WALLOPS ISLAND FLIGHT FAC, VA US station, 23.2 miles from Somerset County, supplies the 3,957 HDD and 1,358 CDD this estimate runs on. That combined heating-and-cooling load ranks Somerset County 2054th nationally by total degree days — the 35th percentile. One local detail the R-value alone won't tell you: Somerset County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
The smaller top-up scenario
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $186/year saved — roughly 12.2 years to break even. Call this borderline rather than a clear win.
Getting it done in Somerset County
Actual quotes will vary by attic access, existing debris, and whether the job needs air sealing first. Treat the $3,480 figure above as a planning number for Somerset County, not a bid - contractors typically charge a $600 minimum regardless of job size.
Where these figures come from
Somerset County's R-60 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-60 is the target here specifically.
