Frequently asked
Is $3,250 a fair price for AC condenser (outdoor unit) replacement in Maryland?
Yes. $3,250 is right around what most homeowners in Maryland pay. Anything from $660 to $7,590 is inside the normal range for an HVAC company; above $7,590 it is worth getting a second quote.
Why do quotes for the same job vary so much?
Tonnage and efficiency rating (SEER2); higher efficiency costs more up front. Compatibility with the existing indoor coil; a mismatch may force a full-system replacement. Company overhead matters too: a large company with trucks, dispatchers and a warranty department charges more than a one-person shop, and both can be honest prices.
When should I get a second quote?
Any time a quote lands above $7,590, or when the contractor cannot break it into parts, labor and fees. Ask for the itemized version, ask what would change the price, and confirm licensing and insurance. You can also paste the quote into the free QuoteJury checker for an instant second opinion.
