AC, furnace, or heat pump: repair or replace?
Estimates and published rules of thumb only. Repair ranges come from HomeAdvisor (heat pump rules from Angi) and replacement bands from Angi and HomeAdvisor. They are not bids from this site.
Got a repair quote on an older AC, furnace, or heat pump? This checks it against the repair-versus-replace rules of thumb HomeAdvisor publishes (Angi's, for heat pumps), using cited repair ranges and the cited replacement bands from our HVAC estimator. It shows each rule on its own. It is not a verdict and not a bid; a licensed technician who has seen your system should make the call.
No published NoVA-specific installed-cost data. Ranges are national (or Washington, DC where noted). They are estimates, not bids from this site.
Safety first: if you smell gas or a carbon monoxide alarm sounds, leave the home and call your gas utility's emergency line or 911 from outside. Do not wait on a cost comparison.
