How Much Does HVAC Repair Cost?

How Much Does the Average HVAC Repair Cost?

How much you’ll pay for an HVAC repair depends on the system (furnace, AC, radiator, boiler), what failed (sensor vs. compressor), ease of access, and whether parts are in stock. Diagnosis fees are typically credited toward the repair.

Heater Repair Costs

Below are typical ranges. The final price depends on the part, access, and brand.

• Furnace: Expect to pay $150 to $900 for common repairs like igniters, flame sensors, control boards, blower motors, and limit switches.
• Radiator: You’ll pay around $150 to $700 for fixes like air bleeding, valve replacement, and leak repair. Electric radiators are usually on the lower end.
• Boiler: Costs typically average $200 to $1,800 for common repairs: circulator pumps, expansion tanks, zone valves, and control boards.

Heater Tune Up Cost

A seasonal heater tune up typically runs from $90 to $200. Expect safety checks, cleaning, filter review, and performance testing.

Home AC Repair Costs

Whether you have central air, a ductless system, or room units, costs vary by part and refrigerant type.

• Central AC: $200 to $1,500
• Ductless Mini Split: $200 to $1,600
• Evaporative Cooler: $100 to $400
• Portable or Window Unit: $80 to $300 (We typically recommend replacement for window and portable AC units as it’s more cost-effective.)

Use this when comparing quotes or searching for ac service cost in your area.

AC Tune Up Cost

A standard AC tune up generally costs $90 to $200, including coil rinse, electrical checks, refrigerant performance check, and thermostat calibration.

HVAC Repair Cost Per Hour

Most HVAC companies charge $75 to $150 per hour for labor, with a $75 to $150 diagnostic fee that may be applied to the repair. After-hours rates can add $50 to $150.

HVAC Repair Cost Per Square Foot

Repairs are not usually priced by size, but for budgeting, older homes commonly average $0.25 to $0.60 per square foot per year for routine maintenance and minor fixes.

HVAC Yearly Maintenance Cost

A single maintenance visit is usually $90 to $200. A maintenance plan covering two seasonal visits often runs from $180 to $450 per year, sometimes with priority service and parts discounts.

What Is the Most Expensive Part of an HVAC System?

Compressors, coils, blower motors, and control boards tend to cost the most. See the table below for a breakdown of HVAC repair costs by part.

*Older refrigerants or extensive leaks can raise costs.

Factors Influencing HVAC Repair Cost

• Season and Response Time: Peak-season and emergency calls cost more.
• System Age and Brand: Older or premium systems may have pricier parts.
• Accessibility: Attics, crawl spaces, or roof units add labor time.
• Part Availability: Special-order components increase time and cost.
• Maintenance History: Dirty coils and clogged filters strain parts and drive failures.
• Electrical or Venting Issues: Code updates or safety fixes can add work.

Repair or Replace: What Is the $5000 Rule for HVAC?

The “$5,000 rule” is a quick check to help you decide whether to repair or replace your HVAC system:

• Multiply your system’s age by the quoted repair cost.
• If the number is over 5,000, replacement often makes more sense from a cost and reliability standpoint.
• If it is under 5,000, a repair may be the better value — especially if the system is well-maintained and parts are still supported.

Example: A 12-year-old AC with a $600 repair → 12 × 600 = 7,200. That points toward considering replacement, particularly if the system uses an older refrigerant, has rising bills, or needs frequent service.
