Cost to repair window AC unit

Window air conditioner repair costs $60 to $250 on average. Replacement parts cost $10 to $150, while the labor to fix a window AC costs $50 to $150 per hour. Replacing a broken window air conditioner that needs several parts as repair service typically costs more than a new unit.

Window AC unit recharge costs

Window AC freon recharge costs $75 to $240. While DIY recharge kits are available for purchase, it is better to call a professional. Since AC units only need a recharge when there is a leak, adding freon without repairing the leak is not a long-term fix.

Window AC repair parts & labor prices

Replacement parts for window units cost $5 to $250, and labor adds $50 to $150 per hour, on average. Only the simplest repairs to replace the least costly parts make sense. If the AC needs more extensive repairs or multiple parts, it is best to replace the entire unit instead.

Window AC repair parts prices

Factors that affect the cost of window AC repair include:

• Labor cost – DIY and handyman repairs are cheaper while hiring an HVAC professional is more costly.

• Part cost – Replacing a single, inexpensive part to repair a window unit extends the life of the air conditioner. Replacing multiple or expensive parts is not cost-effective.

• Machine age – Consider replacing rather than repairing an older AC unit since new units offer better cooling, more energy-efficiency, and upgraded features like Wi-Fi connectivity.

• Component availability – Some older units have parts that are no longer manufactured.

• Other repairs – Window AC unit repairs often lead to other repairs including:

  • Window frame repair costs $150 to $600 on average.

  • Window replacement costs $400 to $650 per vinyl window or $700 to $1,000 per wood window.

  • Window glass replacement costs $50 to $200 for a single pane and $200 to $600 for a double pane window.

Window AC repair labor costs

Hiring a handyman costs $50 to $80 per hour plus the cost of materials to repair a window AC unit. HVAC repair service costs $75 to $150 per hour but finding a technician may be difficult as most consider window units not worth their time to repair.

Many HVAC professionals recommend upgrading to a wall-mounted unit for better cooling with no unsightly components protruding from the window. A ductless mini-split AC costs $2,000 to $6,000 for a single-zone system or $3,200 to $10,500 for a 3-zone system installed.

Window AC maintenance costs

To keep the Window AC running at maximum efficiency, perform these simple DIY tasks throughout the year:

• Clean air filters monthly.

• Replace air filters every 3 months.

• Clean the drain pan and coils annually.

• Cover or remove the unit for winter storage.

While window AC maintenance is an easy DIY project, central HVAC systems require professional maintenance. AC tune-up service costs $70 to $200, and routine annual maintenance costs $120 to $360.

Window AC repair vs. replacement cost

A new window AC installation costs $300 to $1,100 for the unit and labor, compared to $60 to $250 for repair. Replace the entire unit if the repair estimate is more than 50% of the cost for a new window air conditioner.

Replacement is recommended if the unit breaks often, smells bad, sounds odd, or is more than 8 years old. Upgrading to a more energy-efficient system saves money on utility bills, and newer units offer features like remote controls or Wi-Fi connectivity.

Frequently asked questions

Who fixes window AC units?

A skilled DIYer, handyman, or HVAC technician fixes window AC units, depending on the repair. Simple DIY repairs include cleaning filters, coils, or replacing the curtain frame. Call a professional for more complex tasks like replacing the compressor, motor, or fixing a refrigerant leak.

Why is my window AC not cooling?

A dirty air filter is the most common reason a window AC is not cooling. Clean or replace the filters often to remove the dust and dirt blocking the passage of cool air.

Can you fix a window air conditioner?

You can fix a window AC, but major repairs often cost as much as a replacement. Minor repairs and maintenance do not require an HVAC specialist. Often, just cleaning the coils and replacing the filter yourself fixes the problem.

Can you recharge a window air conditioner?

You can recharge a window air conditioner, but some states require certification to handle the toxic refrigerant. A window AC unit only needs a recharge if there is a refrigerant leak. Signs the unit has a leak include:

• The air conditioner runs constantly but doesn’t cool the air.

• Vents are blowing warm air

• Utility bills are higher than normal

• A buildup of ice on the unit

Is it worth fixing a window air conditioner?

It is worth fixing a window air conditioner if the repair involves cleaning or replacing the filter or another inexpensive part. It is not worth fixing the unit if multiple parts like motors or control boards need replacement as the repair cost will exceed the price of a new window AC.

How long do window air conditioners last?

A window AC unit lasts 8 to 10 years or more if properly sized and maintained. A unit that leaks air or is too small for the space works harder and fails sooner. Clean the filter monthly to prolong the unit's lifespan.

Getting quotes from window air conditioner repair services

Before you hire a handyman or AC repair company for window AC repair service, be sure to:

• Look for a handyperson or HVAC contractor that has been in business for 5+ years.

• Browse their reviews on HomeGuide or Google.

• Get at least three estimates featuring comparable equipment.

• Avoid selecting the lowest quote as quality may suffer.

• Get a detailed estimate, contract, and warranty in writing before the work begins.

• Never pay in full upfront. Follow a payment plan, and only make the final payment when fully satisfied.

Questions to ask

• What experience do you have with repairing window AC units?

• Does your estimate include both labor and replacement parts?

• Will you provide a list of references with contact information?

• May I have a copy of your insurance policy for my records?

• Do you guarantee your work or offer an extended warranty?
