HVAC FAQs for Rockville Homeowners
Should I repair or replace the ductwork in my older Rockville home?
Many 1950s-1970s Rockville homes have original ductwork that’s leaking 20-30% of conditioned air. We can test your ducts for leakage and recommend either sealing (for minor leaks) or targeted replacement (for severely degraded sections). In most cases, duct sealing provides dramatic improvement at a fraction of full replacement cost.
