Which system is acting up?

Honest Numbers

Know what things cost before you call

Most contractors hide pricing. We publish the real Baltimore-metro market ranges for installation and replacement — then beat the confusion with one flat-rate quote on every job, repairs included.

Most Popular Upgrade

Heat Pump Installation

$6,500–$14,500Baltimore-metro market range, installed

Our take: flat-rate quote up front, and we file your EmPOWER rebate paperwork for you.

Cooling

Central AC Replacement

$4,100–$8,100Area average ≈ $6,100 installed

Our take: high-SEER2 systems sized to your home, so the efficiency you pay for actually reaches the room.

Heating

Furnace Replacement

$3,500–$8,000Furnace + AC combo avg ≈ $7,800

Our take: we’ll show the hybrid heat-pump math too — often cheaper to run and rebate-eligible.

Air & Ducts

Ductwork

$3,000–$8,000Full ductwork replacement; repairs far less

Our take: bad ductwork wastes 20–30% of your air. Fixing it is often the cheapest efficiency win in the house.

Market ranges reflect independent 2026 cost data for the Baltimore metro (Angi, HomeGuide, regional cost guides). Your exact price depends on home size, equipment tier, and site conditions — which is why every Green Comfort job starts with a free, no-pressure flat-rate quote.

Green Legacy Initiative

Where your service call actually goes

Through the Green Legacy Initiative, a designated share of revenue from the work we do supports conservation programs run by the Maryland Forestry Foundation, a 501(c)(3) working on forests and watersheds across the state.

We opened the partnership with a $2,050 donation in September 2026 and committed to ongoing support. It funds work here in Maryland rather than a generic offset purchased somewhere else.

Green Guardian Club members double the trees planted in their name.

Included with every membership, at no extra cost.

What the funding supports

  • Healthy Forests, Healthy Waters

    Reforestation on Maryland private land that keeps sediment and nutrient runoff out of the Chesapeake Bay watershed.

  • Natural Resources Careers Camp

    A week-long summer program introducing Maryland high-school students to forestry and natural-resource work.

  • Mel Noland Fellowship

    Fellowships for Maryland college and graduate students studying forestry and natural resources.

Partnership announced by the Maryland Forestry Foundation, September 9, 2026.
