Frequently Asked Questions
How much does a new HVAC system cost in Maryland in 2025?
On average, Maryland homeowners spend between $6,000 and $12,000 for a standard replacement. High-efficiency heat pumps or multi-zone systems for larger homes (2,500+ sq ft) can range from $13,000 to $18,000 before rebates.
Is a permit required for HVAC replacement in Maryland?
Yes. Most Maryland counties (including Baltimore, Montgomery, and Howard) require a mechanical permit for any new installation or unit replacement. This ensures the system complies with the International Mechanical Code (IMC) and includes a safety inspection.
What is a Manual J calculation and why do I need it?
It is a professional method to determine the exact heating and cooling load of your home. Maryland building departments often require a summary of these calculations for permit approval to prevent oversized systems that fail to dehumidify properly.
Are heat pumps effective in Maryland's cold winters?
Modern 'Cold Climate' heat pumps are highly effective in Maryland, maintaining efficiency even when temperatures drop below 10°F. Many Maryland utilities offer higher incentives for these specific models to encourage electrification.
