HVAC Repair & Replacement in Rockville, MD: what local homeowners should know

Rockville has 1950s–1960s Twinbrook ramblers and split-levels, 1970s colonials and 2000s-era planned communities like King Farm and Fallsgrove. That mix means Rockville HVAC calls range from replacing aging gas furnaces and central AC to adding heat pumps or ductless mini-splits where older homes lack ductwork. Ask contractors for a load calculation rather than sizing by the old unit.

Before you hire in Rockville

License: Maryland HVACR contractors are licensed by the State Board of HVACR Contractors (Maryland Department of Labor); ask for the license number.
Permits: residential permits for Rockville addresses are issued by the City of Rockville Inspection Services (inside city limits) or Montgomery County DPS (outside the city). Ask each company whether your job needs one and who pulls it.
Local rules: King Farm, Fallsgrove and many townhome communities have HOA design rules.
Compare in writing: get at least two written quotes for the same scope, with warranty terms, cleanup and payment schedule spelled out.

Common questions

Repair or replace? Systems over about 15 years old with a major failure are often better replaced, but get a repair quote too. Ask about utility rebates and federal tax credits for heat pumps.
