Cold, dry air infiltrates through gaps around windows, doors, electrical outlets, and duct connections. On the Western Slope, large temperature swings make these leaks more noticeable and costly.

Weatherstrip doors and windows. Caulk gaps around frames and penetrations. Seal accessible duct joints with mastic or foil tape (not ordinary duct tape). Check the attic hatch and any penetrations into unconditioned spaces.

Improved sealing keeps heated air inside, reduces drafts, and allows your furnace to cycle less often. Combined with proper insulation levels recommended for Climate Zone 5B, sealing delivers noticeable comfort and lower bills.

Cooley’s Heating, Cooling & Plumbing can evaluate duct sealing and overall system efficiency for homes in Delta, Montrose, and Mesa counties.

Key Takeaways

• Seal gaps around windows, doors, and ducts.
• Use proper materials for lasting results.
• Better sealing improves comfort in our cold, dry winters.
