3 Free HVAC Estimate Templates (2026) | Pricing + Markup Guide

HVAC estimates can make or break your HVAC contracting business. Price too high and the homeowner goes with your competitor. Price too low and you eat the cost of that extra line set, the duct modification you did not plan for, or the crane rental to get the unit on the roof.

The HVAC industry is also dealing with major changes right now. The shift from R-410A to R-454B refrigerant, new SEER2 efficiency standards, and rising equipment costs mean your old estimates are already outdated. If your template still has 2024 equipment pricing, every estimate you send is wrong.

These three templates cover the most common HVAC jobs: a residential system replacement, a new construction install, and a service/repair call. Each includes realistic 2026 equipment costs, labor hours, and markup formulas you can adjust for your market.

TL;DR: A residential HVAC system replacement runs $8,000 to $15,000 installed in 2026. New construction installs for a 2,400 sq ft home land around $16,000 to $20,000. Service and repair calls should average $500 to $900. Target 40 to 50% gross margin on replacements and 55 to 65% on service calls. Download our three free templates below with every line item broken out, then adjust equipment pricing from your distributor and plug in your local labor rates.

Tips for This Template

• Always include the Manual J load calculation as a line item. It shows the homeowner you sized the system properly and protects you if they question the equipment size.
• R-454B refrigerant is now the standard for new equipment in 2026. It is mildly flammable (A2L classification), so make sure your techs are trained and your estimate accounts for any safety requirements.
• Offer good-better-best options. Price a 14 SEER2, 16 SEER2, and 18+ SEER2 system. Most homeowners pick the middle option, which is exactly what you want.
• Include the WiFi thermostat. It costs you $175 but adds $300+ in perceived value and gives the homeowner a feature they will show off to friends.

Tips for This Template

• New construction HVAC requires Manual J (load calculation) and Manual D (duct design). Include both in your estimate. The GC expects you to design the system, not just install it.
• Airflow balancing at startup is critical. Do not skip this step. Rooms with unbalanced airflow lead to comfort complaints and callbacks.
• Coordinate with the framing and insulation crews using construction scheduling tools. Your ductwork needs to be installed before insulation, and your equipment location needs to be framed correctly.
• Include a note about attic access requirements. The air handler needs a platform, a working light, and a service clearance that meets code.

Labor Subtotal

Other Costs

Item	Quantity	Unit	Unit Cost	Total
Trip/service charge	1	each	$89.00	$89.00
Other Subtotal				$89.00

Summary

	Amount
Parts	$40.00
Labor	$360.00
Other Costs	$89.00
Direct Cost Subtotal	$489.00
Overhead (15%)	$73.35
Profit (25%)	$140.59
Total Estimate	$702.94

Tips for This Template

• Service calls should carry your highest profit margins (20-30%). The homeowner is paying for your diagnostic skill, fast response, and the convenience of a stocked truck.
• Always test the full system after a repair, not just the failed component. A bad capacitor often damages the contactor over time, and vice versa. Replacing both when one fails is smart preventive maintenance.
• Offer a maintenance agreement during every service call. Automated client reminders make follow-up easy. A customer who just spent $700 on an emergency repair is the most receptive audience for a $150/year maintenance plan.
• Take before-and-after photos of the condenser coil cleaning with photo management tools. Customers love seeing the difference, and it justifies the labor charge.

Adjusting These Templates for Your Business

Know Your Equipment Costs

Equipment is the largest line item in most HVAC estimates. Build relationships with 2-3 distributors and compare pricing. Volume discounts can save you 5-15% on equipment, which goes straight to your bottom line.

Calculate Your True Labor Cost

Use job costing tools to track your true labor burden. HVAC technician wages plus workers comp, insurance, payroll taxes, and benefits add up fast. If your lead tech makes $32/hour, the true cost is probably $44-50/hour once you add everything. Your billing rate needs to cover that cost plus overhead and profit.

Offer Good-Better-Best

Present three options on every replacement estimate. The “good” option is the minimum code-compliant system. The “better” option is what you recommend. The “best” option is the premium system with all the features. Most customers pick the middle, and some surprise you by going premium. You never sell the top option if you never present it.

Move to Digital Estimates

HVAC customers compare 2-3 bids before deciding. The contractor who sends a professional, itemized estimate first often wins the job. Projul’s estimating tools let you build and send HVAC estimates from your truck right after the site visit. No going back to the office. No delays. Schedule a demo to see how it works.

How to Estimate an HVAC Job Step by Step

Whether you are pricing a system replacement or a full new construction install, follow this process to build accurate HVAC estimates every time.

Step 1: Schedule and Complete the Site Visit

Never price HVAC work without walking the property first. During the visit, document the existing equipment (brand, model, age, refrigerant type), measure the space, check ductwork condition, inspect electrical panels, and note access challenges like tight attics or rooftop units. Take photos of everything. A 30-minute site visit saves hours of rework later.

Step 2: Run a Load Calculation

Use Manual J software like Wrightsoft or CoolCalc to size the system correctly. Input square footage, insulation values, window areas, climate zone, and orientation. The load calculation tells you the exact tonnage and BTU output the home or building needs. Include this as a line item on your estimate so the customer sees you did the math.

Step 3: Select Equipment and Get Distributor Pricing

Based on the load calculation, pick equipment that fits the job. Call your distributor for current pricing. Equipment costs shift throughout the year, so never rely on last month’s price sheet. Build your estimate with at least two options (good and better) so the customer has a choice.

Step 4: Estimate Labor Hours

Break labor into specific tasks: removal, equipment setting, duct connections, electrical, line set, vacuum and charge, startup, and cleanup. Assign hours and rates for each. Be honest about how long each task takes with your crew. Underestimating labor is the fastest way to lose money on HVAC jobs.

Step 5: Add Materials, Permits, and Other Costs

List every material: line sets, refrigerant, condensate drains, pads, disconnects, transitions, and miscellaneous hardware. Add permit fees, disposal costs for old equipment, and warranty registration. Missing a $200 permit or $75 haul-off fee adds up across dozens of jobs per year.

Step 6: Apply Overhead and Profit Markup

Add your overhead percentage (typically 12-18%) to cover office rent, insurance, trucks, software, and admin staff. Then add your profit margin. For replacements, target 12-18% net profit. For service calls, target 20-30%. If your numbers look tight, check your labor rates and overhead allocation before cutting profit.

Step 7: Review, Send, and Follow Up

Double-check every line item before sending. Use estimating software to send professional estimates from your phone right after the site visit. The first contractor to send a clean, detailed estimate wins the job more often than not. Follow up within 48 hours if you have not heard back.

Residential vs Commercial HVAC Estimates

Residential and commercial HVAC work require different estimating approaches. Here is what changes when you move from houses to commercial buildings.

Scope and Complexity

Residential systems are straightforward: one or two zones, a single air handler, and a condenser. Commercial systems involve rooftop units (RTUs), split systems across multiple zones, VAV boxes, building automation controls, and exhaust systems. Commercial estimates need more line items and more detailed scope descriptions.

Equipment Costs

Commercial HVAC equipment costs significantly more. A 10-ton commercial rooftop unit runs $8,000 to $15,000 for the equipment alone, compared to $3,000 to $5,000 for a residential condenser. Commercial estimates also include controls, thermostats for each zone, and integration with building management systems.

Labor and Crew Size

Residential replacements usually need a two-person crew for one day. Commercial installs may require 4-6 technicians over multiple days or weeks. Crane rentals for rooftop work, scissor lifts for high ceilings, and specialized rigging all add labor and equipment costs that do not exist on residential jobs.

Bidding Process

Homeowners compare 2-3 bids and decide within a week. Commercial projects go through formal bid processes with general contractors, architects, and building owners. You may need to provide bonds, insurance certificates, and detailed project schedules alongside your estimate. Project management tools help you track commercial bids and deadlines without dropping the ball.

Profit Margins

Commercial HVAC margins are typically lower per dollar (8-12% net) but the total dollar amount is higher. A $200,000 commercial job at 10% profit nets $20,000. A $12,000 residential replacement at 15% nets $1,800. Many HVAC contractors do both to balance cash flow and profitability.

---

HVAC Equipment Markup: What to Charge and Why

Equipment markup is where a lot of HVAC contractors either leave money on the table or price themselves out of jobs. Here is how to think about it.

Standard Equipment Markup Ranges

For residential replacements, most profitable HVAC companies mark up equipment 40 to 65% over their distributor cost. If you pay $3,200 for a heat pump from your distributor, you are billing the customer $4,480 to $5,280 for that unit. The rest of the estimate (labor, materials, overhead, profit) gets added on top.

For commercial equipment, markups are typically lower (25 to 40%) because the dollar amounts are higher. A $12,000 rooftop unit at 30% markup adds $3,600 in gross profit from that single line item.

For service parts, mark up 100 to 300%. A $18 capacitor billed at $55 to $75 is standard across the industry. The customer is paying for the fact that you had the right part on your truck and the knowledge to install it in 15 minutes.

Do Not Show Your Cost

Never put your distributor cost on the estimate. Show the customer the total price per line item. If they ask for a cost breakdown, you provide equipment, labor, materials, and overhead categories. You do not owe anyone a look at your supply house invoice.

Volume Discounts Matter

If you are installing 8 to 10 systems per month from one distributor, negotiate better pricing. A 5% volume discount on equipment across 100 installs per year puts an extra $25,000 to $40,000 in your pocket. Track your purchase volume with budgeting tools so you have real numbers when you negotiate.

Seasonal Pricing Strategies for HVAC Contractors

HVAC demand swings hard with the seasons, and your pricing should reflect that. Contractors who charge the same price in January as they do in July are leaving money on the table during peak season and sitting idle during slow months.

Peak Season (June to August)

This is when the phone rings off the hook. Emergency AC failures, system replacements that cannot wait, and homeowners who finally pull the trigger after sweating through the first heat wave. During peak season:

• Your schedule is full 2 to 3 weeks out. Charge accordingly.
• Raise your labor rates 10 to 15% or reduce discounts. Demand supports it.
• Prioritize replacement jobs over repairs. A $12,000 system swap is a better use of your crew’s time than a $500 capacitor replacement.
• Use scheduling software to maximize crew utilization. Every gap in your schedule during July costs you $500 to $1,000 in lost revenue.

Shoulder Season (March to May, September to November)

These months are when smart contractors build their backlog. Homeowners are thinking about HVAC but are not desperate yet. Offer incentives to pull work forward:

• Maintenance agreement sign-ups with a free inspection
• “Beat the heat” early replacement pricing (5 to 8% off if they schedule before June)
• Financing promotions with lower rates or deferred payments

Track every lead that comes in during shoulder season with a CRM. A homeowner who calls in April for a quote but does not buy is your hottest prospect in June when their AC dies.

Off Season (December to February)

Unless you also do heating work, winter is slow for AC contractors. Use this time to:

• Market furnace tune-ups and heating system inspections
• Train your team on new equipment and refrigerant handling (R-454B certification if they do not have it)
• Build maintenance contract revenue to smooth out cash flow (see section below)
• Offer your lowest replacement pricing to fill the schedule

---

Maintenance Contract Pricing for HVAC Contractors

Maintenance agreements are the most underrated revenue stream in HVAC. They create predictable monthly income, keep your techs busy during slow periods, and give you first crack at replacement sales when systems fail.

What to Include in a Residential Maintenance Plan

A standard residential HVAC maintenance agreement includes two visits per year (one for cooling, one for heating). Each visit covers:

• Filter replacement (standard 1” filter, or charge extra for 4” media filters)
• Condenser coil cleaning
• Evaporator coil inspection
• Refrigerant pressure check
• Electrical connection tightening
• Thermostat calibration
• Condensate drain flush
• Safety control testing

How to Price Maintenance Contracts

Most HVAC contractors price residential maintenance agreements between $150 and $300 per year for a single system. Here is how to figure out if that works for you:

Your cost per visit: 1 hour of tech time ($45 to $55 fully burdened) plus a truck roll ($30 to $40 in fuel, wear, and overhead) plus a filter ($5 to $15). Total: roughly $80 to $110 per visit, or $160 to $220 per year for two visits.

Your price: $180 to $250 per year covers your costs and puts 15 to 30% in your pocket from the maintenance alone. But the real money is in the upsell. A tech who finds a cracked heat exchanger during a fall tune-up just created a $10,000 replacement opportunity with a customer who already trusts you.

Add Priority Scheduling and Discounts

Sweeten the deal for maintenance customers by offering priority scheduling during peak season and 10 to 15% off repairs. These perks cost you almost nothing but dramatically increase sign-up rates. Use time tracking to measure how long maintenance visits actually take so you can tighten your pricing over time.

Selling Maintenance on Every Service Call

Every service repair customer should hear about your maintenance plan before you leave the property. A homeowner who just paid $700 for an emergency repair is the easiest maintenance sale you will ever make. “For $199 a year, we come out twice to make sure this does not happen again.” Track your conversion rates in your CRM and coach techs who are not selling.

Build and send maintenance proposals from your phone with Projul’s mobile app so you can close the deal on the spot instead of sending a follow-up email that gets ignored.

Common Mistakes That Cost HVAC Contractors Money on Estimates

Not doing a load calculation. Guessing equipment size by square footage leads to oversized or undersized systems. Both cost you money in callbacks and unhappy customers. A $150 Manual J calculation protects a $12,000 installation.

Using old equipment pricing. HVAC equipment prices increased 15-25% between 2023 and 2026 due to new efficiency standards and refrigerant transitions. If your template has old prices, every estimate is wrong.

Forgetting duct modifications. New equipment rarely drops into the exact same footprint as the old unit. Plenum transitions, duct resizing, and return air modifications add $200-800 to most replacement jobs. Price them or eat the cost.

Not including the permit. HVAC replacement permits cost $150-350 in most cities. Some contractors skip the permit to save the customer money (and win the bid), but that creates liability, warranty, and resale problems.

Underpricing service calls. Your service truck costs $400-600 per day in fuel, insurance, maintenance, and inventory. If your service calls do not average $500+ in revenue, the truck is losing money.

---

What Every HVAC Estimate Needs Beyond the Numbers

• Equipment specifications. Brand, model, tonnage, SEER2 rating, and refrigerant type. Do not just write “3-ton AC.”
• Load calculation reference. Note the Manual J results or attach the calculation.
• Scope of work. Write a clear scope of work. “Remove existing 3-ton Carrier system. Install new Trane XR16 heat pump and air handler. Reuse existing ductwork with plenum modifications. New thermostat, line set, and electrical connections.”
• Timeline. “Equipment replacement: 1 day. Start within 1 week of signed contract.”
• Warranty details. Equipment manufacturer warranty (5-10 years), your labor warranty (1-2 years), and what is required to maintain both (annual maintenance).
• Payment terms. “50% deposit at scheduling, 50% due at completion and successful startup.” Use invoicing software to collect payments faster.
• Exclusions. “Does not include ductwork replacement, attic insulation, electrical panel upgrades, or smart home integration.”
• Rebates and incentives. List any utility rebates or tax credits the homeowner qualifies for with a heat pump. This can be a deciding factor.
