HVAC Intake Forms: What to Capture Before Rolling a Truck

We’ve all been there. A call comes in — “my AC isn’t working” — and you send a tech out with a general idea of the problem. He shows up to find a 30-year-old R-22 package unit on a commercial roof with no ladder access, no disconnect in sight, and a customer who expects it fixed in an hour for fifty bucks. That visit was dead before it started.

The fix isn’t better technicians. It’s better information at the front desk. A well-built HVAC intake form turns a vague service request into an actionable job ticket. Your dispatcher knows what the tech is walking into. Your tech knows what to load on the truck. Your office knows what to quote. Here’s what that form needs to include — and why each section earns its space on the page.

Customer and property basics

This part seems obvious, but it’s where most callback problems actually start. You need more than a name and phone number. Capture the full service address (not just the billing address — they’re often different), gate or access codes, whether there’s a dog in the yard, and any parking restrictions. For commercial properties, note the property manager’s contact info separately from the tenant who placed the call. Plenty of commercial HVAC jobs stall because the tech can’t get roof access and nobody on site has the key.

Also capture whether this is a residential or commercial property. That distinction drives everything downstream — the equipment you’ll likely encounter, the pricing structure, and whether you need to coordinate around business hours or tenants. A “company (if applicable)” field handles the commercial cases cleanly without cluttering the form for homeowners.

If you handle electrical work as a combined HVAC/electrical shop, the property section of your intake form is basically the same across trades — the difference is what comes after it.

Equipment identification

This is where HVAC intake diverges sharply from other trades. A plumber doesn’t usually need to know what brand your water heater is before showing up. But an HVAC tech absolutely needs to know what equipment is on site, because the difference between a Carrier split system and a Mitsubishi ductless mini-split is the difference between two completely different skill sets, tool kits, and parts inventories.

System type and configuration

Your form should have checkboxes or a dropdown for the common configurations: central air (split system), package unit, heat pump, ductless mini-split, window units, and geothermal. For commercial properties, add rooftop units (RTUs) and VRF systems. Most homeowners won’t know the exact system type, but asking the question prompts them to look — and a photo of the outdoor unit (which your questionnaire can request) fills in the gaps.

Make, model, and serial number

The data plate on the outdoor unit tells you almost everything: manufacturer, model number, serial number, tonnage, refrigerant type, and manufacturing date. Train your front-desk staff to walk customers through finding it. The serial number alone lets you pull warranty status, factory bulletins, and known defect patterns before the truck ever leaves the shop.

Refrigerant type

This matters more than most customers realize. If the system runs R-22 (Freon), the customer needs to understand that refrigerant is no longer manufactured and costs have gone through the roof. A tech showing up to recharge an R-22 system without that conversation happening first is going to have a very awkward moment at the invoice. R-410A systems are the current standard for residential, but you’ll also encounter R-407C and R-134a on commercial equipment and older R-22 retrofits. Newer units are starting to ship with R-32 and R-454B as the industry moves toward lower-GWP refrigerants.

Capturing the refrigerant type on intake lets your dispatcher flag R-22 jobs for a cost conversation before the visit and ensure your tech has the right recovery equipment and gauges on the truck.

Tonnage and capacity

Residential systems typically range from 1.5 to 5 tons. Commercial goes much higher. The tonnage tells you whether the system is appropriately sized for the space (an undersized unit running nonstop in July is a different diagnosis than a correctly sized unit that suddenly stopped cooling). It also affects parts — a 2-ton condensing unit uses different components than a 5-ton unit, even from the same manufacturer.

Symptom description and service history

The “what’s wrong” section is the heart of the intake form. But “it’s not working” isn’t useful. Structure this section with specific prompts that pull out actionable details.

Current symptoms

Use a checkbox grid — check-all-that-apply format works well here. Common symptom categories for HVAC:

• Not cooling / not heating / weak airflow
• System runs but doesn’t reach set temperature
• Short cycling (turns on and off frequently)
• Strange noises (grinding, squealing, banging, buzzing)
• Water leak or ice buildup on indoor unit
• Unusual odors (burning, musty, chemical)
• Thermostat unresponsive or reading incorrectly
• High energy bills with no obvious cause
• System won’t turn on at all

Follow the checkboxes with an open text field for additional detail. A customer might not think to mention that the system works fine downstairs but not upstairs — unless you give them space to say it.

When did the problem start?

Timing is diagnostic gold. A system that stopped cooling on the first 95-degree day of summer is probably just overwhelmed or low on charge. A system that stopped heating the day after a power outage might have a tripped breaker or blown control board. Note whether the problem is constant, intermittent, or worsening over time.

Prior service and repairs

Ask when the system was last serviced, by whom, and what was done. If another company touched it recently, your tech needs to know that — both for diagnostic purposes and because warranty work may be in play. A field for the last filter change date is surprisingly useful: a clogged filter is the single most common cause of HVAC performance complaints, and knowing it hasn’t been changed in 14 months points your tech in the right direction immediately.

Thermostat and ductwork details

The thermostat is the brain of the system, and a surprising number of “HVAC problems” are actually thermostat problems. Capture what type is installed: manual, programmable, or smart (Nest, Ecobee, Honeywell Home, etc.). Smart thermostat issues often have a Wi-Fi or software component that changes the troubleshooting approach entirely. Note whether the customer has recently changed their thermostat — a DIY smart thermostat install with incorrect wiring is a regular source of service calls.

Ductwork condition matters too, particularly for airflow complaints. Ask about visible duct damage, disconnected runs in the attic or crawl space, and whether certain rooms have always been hotter or cooler than others. That last question distinguishes a system problem from a duct design problem, which is a completely different scope of work.

If your shop also handles plumbing work, you already know that the property details section is where most intake forms either save or waste your time. HVAC is the same — the more you know about the building before dispatch, the fewer surprises on site.

Warranty and maintenance agreement status

Warranty status changes the entire trajectory of a service call. Most residential HVAC manufacturers offer 5-year parts warranties standard, extendable to 10 years if the homeowner registered the unit within 60 to 90 days of installation. But here’s the catch: a huge number of customers never register, and they don’t know that. Your intake form should ask for the installation date (or approximate year) and whether the unit was registered with the manufacturer.

If your company installed the system, you should have this in your records already. If another company did, the warranty situation is murkier — labor warranty is almost always with the installer, not the manufacturer. Capturing this upfront prevents the uncomfortable conversation where your tech diagnoses a $1,200 compressor replacement and the customer says “but it’s still under warranty” — and it turns out the parts warranty expired because nobody registered it.

Also note whether the customer has a seasonal maintenance agreement with you or another company. Agreement customers often get priority scheduling and discounted rates, and your dispatcher needs to know that before quoting standard pricing.

Commercial vs. residential: when to use separate sections

Some shops run two entirely separate intake forms for commercial and residential. That’s fine if your volume justifies it. But a single form with a conditional commercial section works just as well for most operations. The key fields that only apply to commercial jobs:

• Building management company and contact
• Required insurance certificates (COI) before work can begin
• Roof access requirements (keys, hatches, ladder needs)
• Hours of operation and any restrictions on work times
• Number of units on the property (commercial buildings often have multiple RTUs)
• Building automation system (BAS) type, if applicable
• EPA 608 certification type needed (Type I, II, or Universal — your tech should carry Universal, but it’s worth confirming for the specific equipment)

The commercial section doesn’t need to be long, but missing any of these items can turn a routine commercial service call into a wasted trip.

Putting it all together

A complete HVAC intake form isn’t a bureaucratic exercise. It’s dispatch intelligence. Every field on the form should answer a question that, left unanswered, would cost you time or money on site. Equipment type tells your tech what to load. Refrigerant type prevents sticker-shock conversations. Symptom checkboxes give your tech a diagnostic head start. Access details prevent lockouts. Warranty status prevents billing disputes.

The best HVAC shops we’ve talked to treat the intake form as the first billable step of the service call — not paperwork to rush through. A front-desk person who spends five minutes getting thorough intake information saves the technician thirty minutes on site and eliminates the second truck roll that kills your margins.
