Considering HVAC or AC replacement in Calverton, Maryland? The cost typically ranges from $6,500 to $14,000 for a complete system replacement. This variation stems from several factors, including the size of your home, the efficiency rating of the new system (SEER2 for AC and HSPF for heat pumps), the complexity of the installation, and whether you choose to upgrade ductwork. Before you proceed, take a look at our complete Maryland Heating & Cooling guide to understand state regulations and best practices.
Material Prices
While this table displays common HVAC material costs, the biggest expense is the HVAC system (furnace, heat pump, AC unit) itself. Ductwork, refrigerant lines, and other components also contribute to the overall price.
| Material/Component | Average Price (Installed) | Notes |
|---|---|---|
| High-Efficiency Heat Pump (3-Ton) | $4,500 – $8,000 | Ideal for Maryland’s 4-season climate |
| Central Air Conditioner (3-Ton, 16 SEER2) | $3,500 – $6,000 | Consider higher SEER2 for better efficiency. |
| Gas Furnace (80% AFUE) | $2,500 – $4,500 | Common for homes with existing gas lines. |
| Ductwork Replacement (per vent) | $200 – $500 | Essential for optimal system performance. |
| Whole-House Dehumidifier | $1,500 – $3,000 | Highly recommended to combat Chesapeake humidity |
Local Factors
In Calverton, which falls under Montgomery County, you’ll need to secure the necessary permits for HVAC replacement. Contact the Montgomery County Department of Permitting Services to understand specific requirements and fees. Expect to pay between $100 and $500 for permits, depending on the scope of the work. Installation labor rates in the DC-Baltimore corridor are generally higher than the national average, typically ranging from $75 to $150 per hour. When selecting a contractor, ALWAYS verify their Master’s license with the Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors (DLLR). Using an unlicensed contractor is a significant risk.
Weather Impact
Calverton’s humid subtropical climate presents unique challenges for HVAC systems. The hot, humid summers demand powerful and efficient cooling, while the cold, snowy winters necessitate reliable heating. High-efficiency heat pumps are an excellent choice, providing both heating and cooling efficiently. Given the high humidity levels associated with the Chesapeake Bay, consider a variable-speed unit and potentially a whole-house dehumidifier to prevent mold growth and improve indoor air quality. Don’t forget to explore “EmPOWER Maryland” programs for rebates on qualifying high-efficiency SEER2 units, which can significantly reduce your upfront costs. Also, ensure your new system includes advanced air filtration (MERV 13 or higher) to combat urban pollution and seasonal allergens common in the area.

FAQ
- How long does HVAC or AC replacement typically take?
Most residential HVAC replacements can be completed in 1-3 days, depending on the complexity of the installation and whether ductwork modifications are needed. - What SEER2 rating should I look for in a new AC unit?
In Maryland, aim for a SEER2 rating of 16 or higher to maximize energy efficiency and potentially qualify for rebates. - Should I replace my furnace and AC at the same time?
If both your furnace and AC are nearing the end of their lifespan (15-20 years), it’s often more cost-effective to replace them simultaneously. This also ensures optimal system compatibility and performance.
