There is no reliable single price for an AC repair: the cost depends on the fault, labor, equipment model, warranty, and parts required. Ask each HVAC contractor for the diagnostic charge, any after-hours surcharge, an itemized written estimate, whether the fee applies to the repair, and how parts and workmanship are covered. Compare like-for-like diagnoses before deciding.

Search the company name or contractor number using the Virginia DPOR License Lookup, then confirm that the record matches the business quoting your job and the relevant work classification. Ask for current insurance documentation. For work involving refrigerants, the EPA explains when Section 608 technician certification is required.

Consider the equipment's age, repair history, efficiency, condition, comfort problems, and the cost of the proposed repair relative to a properly sized replacement. The EPA recommends professional evaluation when equipment is more than ten years old or is not keeping the home comfortable; that is not a rule that every ten-year-old unit must be replaced. Request both options in writing when a major component fails.

Yes—heat pumps are part of the published offerings of the Arlington-based companies reviewed here. Ask about heating performance, ductwork, electrical capacity, thermostat controls, system sizing, equipment and labor warranties, and ongoing maintenance before signing a heat pump installation contract.

Availability differs by contractor. Air Master advertises 24/7 emergency service on its website, but individual appointment capacity and any after-hours fee must be confirmed by phone. Do not assume a contractor offers guaranteed same-day service simply because its website mentions urgent repairs.

Follow the equipment manufacturer’s maintenance schedule, check filters at the recommended intervals, and consider seasonal professional checks for heating and cooling systems. Filter needs vary with the home, occupants, pets, and system design. Keep outdoor equipment clear and avoid attempting refrigerant or electrical work yourself.

Request the exact equipment model and efficiency rating, load-calculation basis, permits when required, changes to ducts or electrical work, removal of old equipment, start-up testing, warranty terms, estimated timeline, payment schedule, and any financing costs. Confirm whether subcontractors will be used and who is responsible for follow-up service.
