Local context for Rockville

  • Avent Contracting LLC is one of 54 businesses we list for ac services in Rockville (76 HVAC businesses in total).

Buying a new AC or heat pump in Virginia

  • Virginia is in the DOE Southeast region: new central air conditioners installed since January 1, 2023 must meet at least 14.3 SEER2 (13.8 SEER2 for systems 45,000 BTU/h and larger). Heat pumps must meet 14.3 SEER2 and 7.5 HSPF2 nationwide.
  • Since 2025, new systems are built for lower-impact refrigerants such as R-454B or R-32. Ask which refrigerant a quoted system uses and for its AHRI certificate number, which confirms the matched system’s rated efficiency.

    We have no insurance details on file. Ask for a certificate of general liability and workers' compensation coverage before anyone works in your home.

  • Ask who pulls the permit

    Replacing an AC, furnace, heat pump or water heater usually needs a local permit and inspection. A licensed contractor normally pulls it — ask that the permit is included in the written quote.

  • Ask for local references

    We do not have review data for this business yet. Ask for two or three recent customers near you.

  • Virginia homeowner protection

    Virginia's Contractor Transaction Recovery Fund can compensate homeowners for certain losses caused by a contractor — but only if the contractor held a valid DPOR license when the contract was signed.
