Work packages: what moves to the assistant and what stays with your team

An HVAC virtual assistant is a dedicated remote customer service rep and office coordinator for a heating and cooling contractor. You buy a seat, measured in hours, that answers and returns calls, books jobs onto the dispatch board, keeps customers informed, chases open quotes, renews maintenance agreements, sends invoices and asks happy customers for reviews. It works inside your own field service software, phone system and inbox. In many HVAC shops this work lands today on the owner or a technician between jobs.

Buy it by work package, not as "office help". Each package names the inputs, the output and the person who signs off, so the assistant knows where its job ends and a technician's or the owner's begins. Most buyers start with calls, booking and confirmations, then add the rest after the first month.

The call script boundary: say, route, never

An HVAC phone line carries a few calls where a wrong word matters: a caller who smells gas, a carbon monoxide alarm going off, an elderly customer without heat in a cold snap. The assistant is not a technician and must not act like one. Write the script before day one and put this table in the onboarding pack. The assistant owns the first two columns; the third never moves.

Review recorded calls against this table weekly for the first month. If the script has no answer for a call, the assistant takes a message and routes it; you then add the missing line to the script.

This file is a buying guide, not safety, technical or legal advice. Your own written script, approved by you, decides what callers hear.

A statement of work you can copy

Fill in the brackets and attach the result to the request and to the agreement. Each clause answers a question that otherwise comes up in week two.

Coverage models compared

A common setup for a small shop: the assistant covers the business day and the evening shoulder, and an answering service takes overnight calls with the same gas and CO script, passing them to the on-call technician. For the wider choice between a dedicated person and a managed team, see dedicated team vs staff augmentation. Contact-center providers are scored in the customer service outsourcing drawer.

Total cost of ownership: in-house CSR vs HVAC VA

Sources: US Bureau of Labor Statistics, Occupational Outlook Handbook, May 2025 median: customer service representatives $44,770 a year ($21.53 an hour); heating, air conditioning and refrigeration mechanics and installers $61,010 a year ($29.33 an hour); both checked on bls.gov 13 November 2026. Employer FICA rate from the IRS; BLS Employer Costs for Employee Compensation for the benefits share. VA rate = our recruiting partner's published HVAC admin rate, billed monthly in arrears for hours worked.

A part-time seat (80 hours a month) costs $520–$800 a month, or $6,240–$9,600 a year. The second comparison is the one many owners skip: the technician's time. BLS puts the median HVAC mechanic and installer at $29.33 an hour before payroll costs, and every hour a technician spends returning calls, sending invoices or chasing a quote from the van is an hour not billed to a customer. The same goes for the owner who books jobs at night. Count those hours in your own shop for one week, then price them against a seat at $6.50–$10.

Sizing the seat by season

HVAC demand swings with the weather, so size the seat from two weeks, not one: a normal shoulder-season week and a peak week from last summer or winter. Have the office note every item from the work packages above and the minutes each takes, then multiply out to a month. The example below is for a residential service company with six technicians; the inputs are illustrations, not benchmarks.

As a starting point: a two- or three-technician shop where the owner still answers the phone often begins at 80 hours a month on calls, booking and invoices; six or more technicians usually fill a full-time seat; a shop running a large agreement base or commercial accounts may need two. Ask the provider in writing how extra hours and a second seat are arranged before the season starts, not during the first heat wave.

The seasonal operating calendar

The seat earns most of its keep in the months between peaks, when there is time to fill the board ahead of the weather. Put this calendar into the onboarding pack and adjust the months to your climate.

Maintenance-agreement administration

Service agreements (an annual plan with scheduled tune-ups, usually with priority booking and member discounts) only pay off when visits actually happen and renewals actually go out. That is admin work, and it is the package most often left undone in a busy office. You set the plan's price, terms and discounts; the assistant runs these steps:

1. One list: every active agreement in your field service software, with start date, renewal date, visits due and the equipment covered.
2. Visits booked ahead: spring and autumn visits booked in the shoulder weeks, before members have to ask.
3. Renewal notices: sent on the window you choose (for example, 30–60 days before expiry), then a call or text if there is no answer.
4. Lapsed members: contacted once with the renewal offer you approved; do-not-call preferences honoured.
5. Monthly report: active agreements, renewals, lapses and visits completed against visits due.

Controls for prices, payments and customer data

The assistant will see home addresses, door codes in job notes, customer phone numbers and payment status. Agree these controls before access starts.

Outbound calls and texts for campaigns follow consent and do-not-call rules; check your process with counsel and keep opt-out flags current in your records.

Service levels and KPIs to put in writing

Measure for 30 days, then set targets from your own numbers. Each measure has a data source you already have.

Avoid one target that sounds good and works badly: "close rate on quotes". The assistant controls how fast and how often a quote is followed up, not the price or the customer's budget. Measure the follow-up and report the close rate to the owner as information.

Vendor questionnaire: thirteen questions

People

1. Does the assistant work only for my company?
2. What phone, call center, field service or HVAC office experience will candidates have, and in which software?
3. Are candidates tested on a recorded mock call (a no-cooling booking, a gas smell caller handled from a script) before I meet them?
4. Do I interview and choose?

Price and terms

5. What is the hourly rate for this role, and what moves it up the range?
6. How are extra peak-season hours or a second seat arranged and billed?
7. Are there recruitment or setup fees? Is there an advance payment, and is it refundable?
8. What is the trial period, the notice period and the replacement policy?

Data and authority

9. Will the assistant work only in my systems, under a named login?
10. Does the provider confirm in writing that the assistant gives no technical or safety advice and quotes only from my price book?

Continuity

11. What is the backup for internet and power outages during my working hours?
12. How is cover arranged during the assistant's leave and public holidays, especially in peak months?
13. If the assistant leaves, how fast is a replacement shortlisted, and who trains them?

Our outsourcing contract checklist covers the clauses behind these answers.

Scope by business type

The same title covers different seats. Place your company in one of these boxes before you request candidates: it decides which packages come first and how many hours you need.

Software the seat works in

Candidates can be matched to the platforms you run. Name them in the request; the provider can put a task in your own system or a demo account into the test.

Product names show tools candidates can be matched to, not endorsements.

Acceptance test before you choose

General customer service skills don't carry over to HVAC without the context. Ask for a short work sample from each shortlisted candidate, built on your own script and software:

• Booking call: a role-played no-cooling call; capture the details, apply your priority rules and book the slot.
• Script call: a caller who smells gas; the right answer is your script, word for word, then the alert to the on-call contact.
• Price question: a caller who wants a replacement price by phone; the right answer is the diagnostic fee and a visit, not a number.
• Board: rearrange a day after a technician calls in sick, following your zone and priority rules.
• Follow-up: a text and a short email to a customer with an open replacement quote, in your tone.

Score each task on accuracy, phone manner and judgment, and listen for one thing above all: does the candidate stop at the script's edge?

Onboarding plan: 30, 60, 90 days

1. Week 1, access and the script: named logins with the agreed permissions; the call script, price book and priority rules read and role-played; shadowing on live calls; booking under supervision.
2. Weeks 2–4, calls and the board: the assistant owns the line during the shift; confirmations and arrival windows running; end-of-day note every day; the owner or dispatcher reviews call recordings, first daily, then sampled weekly.
3. Day 30 review: baseline numbers for the service levels; the seat size checked against the tally; script gaps added.
4. Days 31–60, money and follow-up: invoicing and collections, quote follow-up, review requests.
5. Days 61–90, full scope: agreement administration and the next seasonal campaign, warranty and permit admin, records clean-up; targets written into the agreement from the baseline.

Risk register

Exit and handover

All work stays in your field service software, phone system and inbox, so nothing has to be handed back. At the end of an engagement, ask for a final handover note (open quotes, unpaid invoices, agreement visits due, callbacks promised), remove access the same day and change any shared passwords.

Requesting candidates

Requests sent through this site go to our recruiting partner, a managed VA agency:

1. Send the scope: technician count, service area, software, phone setup, the work packages and hours, using the statement of work above if it helps.
2. Review the shortlist: candidates with customer service, field service or HVAC office experience, screened and tested, usually in about 2 business days.
3. Interview and choose: nothing is paid before you choose; billing is monthly in arrears for hours worked; an assistant who isn't a fit is replaced at no extra cost.

The trade-offs: an agency costs more per hour than a freelancer you recruit yourself, in exchange for screening and replacement; the first month needs the owner's or dispatcher's review time; after the 30-day trial a notice period applies.
