How much should I charge for an AC service call?

Calculate your fully loaded cost per tech-hour (wages, burden, vehicle, overhead) and multiply by your target margin and average call duration including drive time. Most residential HVAC contractors land between $120 and $175 for a diagnostic fee. If your loaded cost per hour is $110 and you want 20% net margin on a 1-hour average call, your floor price is roughly $138. Round up, not down. Pricing below your loaded cost loses money regardless of volume.

What does an AC diagnostic fee include?

A diagnostic or service call fee covers the trip to the property and the first 30 minutes of troubleshooting to identify the problem. It does not include parts, refrigerant, or extended labor for the repair itself. Most contractors quote the repair separately once the diagnosis is complete. Some waive the diagnostic fee if the customer approves the repair, but this reduces effective labor recovery on small-ticket jobs and should be evaluated against your actual margins.

Why do AC service calls cost more on weekends?

Weekend and after-hours calls require overtime pay for technicians (1.5x under FLSA), which increases your labor cost by 40–50% after burden. You're also reducing the tech's availability for the next workday and typically running less efficient routing. The standard industry practice is a 1.5x multiplier on evenings and weekends and 2x on holidays. A $120 weekday diagnostic becomes $180 on a Saturday evening. The premium reflects real cost increases, not arbitrary markups.

Should I waive the AC diagnostic fee if the customer approves the repair?

Only if the repair invoice has enough margin to absorb it. On a $600+ blower motor replacement, waiving a $125 diagnostic barely dents your margin. On a $180 capacitor swap, waiving the same fee cuts your effective labor recovery by nearly 70%. Run the math on your five most common repairs. If waiving the diagnostic drops net profit below 15% on any of them, either stop waiving it for those repairs or raise the repair price to compensate.

What is the average cost of common AC repairs beyond the service call fee?

Capacitor replacement runs $150–$300 total. Contactor replacement is $125–$250. Refrigerant recharges cost $40–$175 per pound of R-410A, with most systems needing 2–4 pounds. Blower motor swaps range from $350–$800. Compressor replacements are $1,200–$2,800. These totals include parts at typical contractor markup (40–65%) plus labor billed at $95–$175/hour depending on market. Control board replacements fall in the $250–$650 range.

AC Service Call Cost: What Contractors Actually Charge

What a Typical AC Service Call Costs

The average AC service call runs a homeowner $89–$175 for a diagnostic visit, with most contractors landing around $120 for the trip charge and first 30 minutes on site. That number comes from aggregated data across home services platforms and aligns with what ACCA member companies report in their benchmarking surveys.

That fee covers driving to the property, diagnosing the problem, and quoting the repair. It does not cover parts or extended labor time. When you factor in the actual repair, total invoices look more like this:

Capacitor replacement: $150–$300
Contactor replacement: $125–$250
Refrigerant recharge (R-410A, per pound): $40–$175 per pound, with most systems needing 2–4 pounds
Blower motor replacement: $350–$800
Compressor replacement: $1,200–$2,800
Control board replacement: $250–$650

These ranges reflect parts at contractor cost plus standard markup (typically 40–65% on parts) and labor billed at $95–$175/hour depending on the market. A contractor in Phoenix or Miami commands different rates than one in rural Iowa, but the spread above captures the middle 80% of the country.

Why Your Service Call Fee Probably Doesn't Cover Your Costs

Most HVAC contractors set their diagnostic fee based on what competitors charge rather than what their trucks actually cost to roll. That's a mistake. Your loaded cost per truck roll includes fuel, insurance, vehicle depreciation, technician wages and burden, tools and test equipment, uniforms, phone, dispatch software, and the opportunity cost of that tech not being on a revenue-generating install.

Run the math on a typical service van:

Tech wages + burden (taxes, workers' comp, benefits): A journeyman HVAC tech earning $28/hour costs you roughly $38–$42/hour fully loaded. The Bureau of Labor Statistics reports the median HVAC mechanic wage at $25.90/hour (May 2023), but experienced techs in metro markets earn $28–$38/hour before burden.
Vehicle cost: The average service van costs $650–$900/month in payment, insurance, fuel, and maintenance. Over 22 working days, that's $30–$41/day.
Overhead allocation: Rent, dispatch, admin staff, software, marketing. For a 3–5 truck shop, this commonly adds $15–$25 per billable hour.

Add it up: if a tech completes 5 calls per day and works 8 billable hours, your cost per hour likely falls between $85 and $135 before you earn a single dollar of profit. A $89 service call fee for a 45-minute visit (including drive time) doesn't just leave no margin; it loses money. This is one of the core reasons contractors lose money on jobs without realizing it until quarterly financials land.

The fix is straightforward: calculate your true cost per hour, decide on your target net margin (15–20% is healthy for residential HVAC service, according to ACCA's operational benchmarking), and set your service call fee accordingly. If your loaded cost per hour is $110 and you want 20% net, you need to bill $138/hour at minimum. A 30-minute diagnostic plus 20 minutes of drive time is roughly 0.83 hours, so your floor service call fee is about $115. Most contractors should be at $125–$150.

After-Hours, Weekend, and Holiday Rates

Emergency and after-hours AC calls carry a premium for a reason. You're paying overtime wages (1.5x under FLSA), burning more fuel, and reducing your tech's recovery time for the next day's schedule. Standard multipliers in the industry:

After-hours (evenings/weekends): 1.5x the standard rate. A $120 diagnostic becomes $180.
Holidays: 2x the standard rate. That same call is $240.
Emergency/same-day priority: $25–$75 flat surcharge on top of the normal service call fee, even during business hours.

Some contractors waive the diagnostic fee if the customer approves the repair. This can make sense for customer acquisition in competitive markets, but it's a margin decision, not a marketing decision. If you waive a $125 diagnostic on a $180 capacitor swap, your effective labor recovery on that job drops sharply. Know your numbers before you offer that concession.

Regional Pricing Differences

Geography moves AC service call pricing by 30–50%. According to BLS occupational data and IBISWorld's HVAC industry report, the highest-cost markets for HVAC service labor are the Northeast corridor (New York, Boston, northern New Jersey), the San Francisco Bay Area, and Southern California. The lowest-cost markets are the rural Southeast and parts of the Midwest.

Typical diagnostic/trip charge ranges by region:

Northeast metro (NYC, Boston, Philly): $135–$195
West Coast metro (LA, SF, Seattle): $125–$175
Sun Belt metro (Phoenix, Dallas, Atlanta, Miami): $99–$150
Midwest and rural South: $75–$120

These differences mostly track with cost of living and prevailing wages. A tech in Phoenix earning $24/hour has a different loaded cost than one in Boston at $36/hour. The mistake is pricing your calls based on a national average rather than your local cost structure. Two contractors in the same ZIP code can have legitimately different rates if their overhead structures differ.

If you're quoting jobs in the field and syncing back to QuickBooks, make sure your item list reflects your actual regional rates, not a template you downloaded three years ago. Using QuickBooks on the job site makes this easier because your techs pull from the same price list, and you can update it once instead of chasing paper.

How to Set Your AC Service Call Price for Profit

Start from costs, not from competitors. Here's the sequence that works:

Calculate your fully loaded cost per tech-hour. Include wages, burden, vehicle, overhead allocation. Most 3–8 truck HVAC shops land between $85 and $135/hour.
Determine your target net margin. The average HVAC profit margin for service work runs 10–25% net, with well-run companies hitting 18–22%. Pick your number.
Estimate average time per service call. Include drive time. For most residential markets, this is 0.75–1.25 hours per call including travel.
Multiply cost × (1 + target margin) × average time. If your cost is $110/hour, your margin target is 20%, and average call time is 1 hour: $110 × 1.25 = $137.50. Round to $139 or $145.
Benchmark against your market. If your calculated price is wildly above local competitors, your overhead may be too high or your route density too low. Fix the cost structure rather than cutting the price.

Track actual job profit on every service call for at least 90 days. Compare invoiced revenue against time and materials per ticket. If you see consistent slippage between quoted and actual, you either have a quoting problem or a scope creep problem. Either way, you can't fix what you don't measure.

Getting Paid on Service Calls Without Chasing

Residential AC service calls should be collected on site, period. There's no good reason to extend Net 30 on a $250 capacitor swap for a homeowner. Commercial and property management accounts are different, but even there, keeping days outstanding below 14 protects cash flow.

For residential, collect payment before the tech leaves. Mobile invoicing tools let you generate the invoice on site, accept card payment, and sync to QuickBooks in one step. If your process still involves the tech writing up a ticket, driving back to the shop, having the office create an invoice, and mailing it, you're adding 7–14 days of float and 30–45 minutes of admin labor per call. That admin cost alone can eat 3–5% of the ticket value on a small service call.

For commercial accounts, set clear payment terms upfront. Net 15 is reasonable for service work. Net 30 is the norm but costs you real money in carrying costs. If you're not sure how to structure this, review your contract invoice payment terms and tighten anything over Net 30.

The contractors who consistently collect fast share two habits: they invoice before leaving the job site, and they follow up automatically within 48 hours on any open balance. Manual follow-up doesn't scale past 2–3 trucks.

Stop Guessing at Whether Service Calls Make Money

Most HVAC contractors know their service call fee. Fewer know whether it's actually profitable after accounting for drive time, callbacks, and parts cost. The gap between gross revenue and net profit on service work is where small shops bleed out over years.
