How much does AC repair cost in Washington, DC?

What ConsumerAffairs lists for DC repairs

None of this is our pricing. It all comes from ConsumerAffairs' 2026 guide to HVAC companies in Washington, D.C., which gives a range for each of the common repairs in the District.

• $110 to $220 for the diagnostic visit
• $290 to $580 to replace a capacitor
• $290 to $655 for a contactor
• $365 to $1,015 for a condenser fan motor

The same page puts a whole new system in DC at $8,700 to $17,400. If your unit is old and the quote in front of you is for one of the big parts, hold it up against that number before you say yes.

Same symptom, very different bill

The call we hear most is warm air from the vents with the outdoor unit still humming. A failed capacitor can do that. So can a compressor on its way out. You can't tell the two apart from the thermostat, and we can't either until the gauges are on.

A bad capacitor or contactor is usually found and swapped in one visit. A refrigerant leak is longer work. The leak has to be found and fixed, the lines pulled into a vacuum and the system recharged to spec, and that labor comes on top of the part. If your unit still runs on R-22, the refill costs the most, because nobody makes it anymore.

Row houses take longer. Most District row houses built between the 1890s and the 1930s were heated with radiators and had no ducts, so the AC went in later, with an air handler in the attic or a closet and the condenser on the roof or out in the rear yard. Carrying gauges and parts up through a roof hatch adds time that a condenser on a ground pad never does.

How we handle the price on a District repair

When you book, we tell you the diagnostic fee on the phone, so the first number you hear isn't at your front door. The technician finds the failed part, shows it to you and explains why it went before money comes up. Then you get the repair price in writing, and nothing gets touched until you say yes to it.

If the unit is past about twelve years and the problem is the compressor or the coil, we write a replacement price next to the repair price so you can compare them. Repairs are booked for the next day with an arrival window. We answer the phone from 7:00 AM to 7:00 PM, every day of the week.

Members of our Biannual Tune-Up Plan, which runs $20 to $30 a month, get 10 percent off repairs. Our labor on a repair is warranted for 60 to 90 days, depending on the job, and the AC repair page covers what a visit includes.

Where these numbers come from

Every dollar figure on this page comes from one place, ConsumerAffairs, "Best HVAC Companies in Washington, D.C. of 2026" (2026). That page lists District ranges for the diagnostic fee, a capacitor, a contactor and a condenser fan motor, plus $110 to $650 for repairs overall and $8,700 to $17,400 for a full replacement. We copied them the way they're published and didn't round or blend them.

We also found an Angi page with a DC price for expansion valves. It priced one brand's part, and we don't publish brand prices, so it stayed out. The fee rule, the plan discount, the warranty and the way we price a repair come from our own records. None of the dollar ranges here comes from our invoices, and none of them is a quote for your house.
