About HVAC Installation & Repair in Rockville
HVAC work covers heating, ventilation, and air conditioning — from furnace and AC replacement to ductwork modification and zoning systems. Regular maintenance extends equipment life, but most units need replacement every 15–20 years.
Typical costs: A new central AC unit installed runs $3,500–$7,500. Furnace replacement is similar. A complete HVAC system (furnace + AC + ductwork) can be $10,000–$20,000+ depending on home size and equipment efficiency rating.
Common projects include:
- Central AC replacement
- Furnace or boiler replacement
- Ductwork installation or modification
- Mini-split / ductless system installation
- Thermostat upgrade and zoning
HVAC replacements and new installations typically require mechanical permits. Equipment changes that affect gas lines or electrical circuits may need additional permits.
Frequently Asked Questions
- How much does hvac installation & repair cost in Rockville?
- Costs depend heavily on system type and home size. A straightforward AC swap on an existing system runs $3,500–$7,500. Switching from forced air to a mini-split system, or adding ductwork, increases cost significantly. Always get 2–3 quotes.
- How do I find a reliable hvac installation & repair contractor in Rockville?
- HVAC contractors should be licensed and insured. Ask about their experience with your specific system type (forced air, boiler, heat pump, mini-split). Get load calculations — a good contractor sizes the system to your home, not just matches what you had before.
- Do I need a permit for hvac installation & repair in Rockville?
- Most HVAC installations and replacements require a mechanical permit and inspection. Your contractor should pull the permit — if they suggest skipping it, that's a red flag.
