Get answers to common questions about hvac services in Rockville, Maryland.
In Rockville, the cost for a full HVAC system replacement typically ranges from $6,500 to $12,000+, depending on system size, efficiency rating, and home complexity. Maryland's moderate but humid summers and cold winters make high-efficiency (16+ SEER AC, 95+ AFUE furnace) systems a valuable investment for long-term comfort and energy savings. Always get itemized estimates from licensed local contractors that include removal of the old unit, new installation, and compliance with Montgomery County permitting requirements.
The optimal times are during the shoulder seasons—early spring (March-April) before AC demand peaks and early fall (September-October) before heating season. Scheduling during these periods ensures greater technician availability, often better pricing, and prevents emergency breakdowns during Rockville's July/August heatwaves or January cold snaps. This proactive timing is crucial for our climate's distinct seasonal shifts.
Yes, Montgomery County requires a permit for all HVAC system replacements and major modifications, which your contractor should obtain. Furthermore, Rockville homes may be subject to county noise ordinances affecting condenser placement. Crucially, all HVAC contractors must be licensed by the Maryland Department of Labor, and we recommend verifying their license and checking for membership with the Air Conditioning Contractors of America (ACCA) of Metro Washington, which serves our area.
Prioritize local, established companies with strong community reputations, verified Maryland master HVAC license, and proper insurance. Look for providers who perform Manual J load calculations for proper sizing—essential for Rockville's varied home ages and insulation levels. Check reviews on platforms like Nextdoor for hyper-local feedback and ask for references from homes in similar neighborhoods like King Farm or Twinbrook.
During extreme heat and humidity waves (common in July/August), it's normal for systems to run longer to maintain temperature and dehumidify. However, constant cycling without cooling effectively indicates a problem like low refrigerant, a dirty coil, or an undersized unit. Given our high summer dew points, proper dehumidification is key; a professional should assess if your system is correctly sized and functioning to handle our specific mid-Atlantic climate.
