How to Get More HVAC Customers

Make maintenance agreements your customer engine

Grow from the customers you already have before you pay for new ones. A maintenance agreement books you into the same homes every year, ahead of the busy seasons, and those visits are where repair work, referrals and replacement jobs come from.

ENERGY STAR recommends annual pre-season check-ups by a contractor, with the cooling system checked in spring and the heating system in fall ¹. A home with both fits a two-visit agreement, which gives you two scheduled conversations a year with every member. Those visits pay off in three ways:

• The first call when something breaks. A member with no heat has your sticker on the furnace and a reason to call you before searching.
• A replacement list built in advance. You see each system's condition twice a year, so you know which ones are near the end before the owner starts shopping.
• Work before the rush. Tune-ups fill spring and fall, ahead of the summer and winter peaks, which keeps techs busy and paid in the quieter months.

That's why a member is worth more than a single service ticket; customer lifetime value shows how to put a number on it. To set the agreement price and perks, see how to price HVAC jobs.

Write the checklist into the agreement

Customers renew what they can see. ENERGY STAR's checklist for a typical check-up includes ¹:

• Check thermostat settings.
• Tighten electrical connections and measure voltage and current on motors.
• Lubricate moving parts.
• Inspect the condensate drain.
• Cooling: clean the evaporator and condenser coils.
• Heating: check gas or oil connections, gas pressure, burner combustion and the heat exchanger.

Treat ENERGY STAR's full checklist as your minimum and print your version in the agreement. ENERGY STAR's reasons double as plain-language explanations when you report findings: dirty coils make the system run longer, raising energy costs and shortening equipment life; a plugged condensate drain can cause water damage and affect indoor humidity; and faulty electrical connections can cause unsafe operation and shorten the life of major components ¹. A photo of the dirty coil next to that sentence explains the repair better than a sales pitch.

Record the equipment on every visit

Every tune-up should update the customer's file: make, model and serial number from the data plate, refrigerant type, approximate age, what you found and what you recommended. That file is your future replacement pipeline. When an aging system needs a major repair, you can show the owner its history instead of guessing.

Note the refrigerant on every unit. U.S. production and import of R-22 (HCFC-22) ended on January 1, 2020. Existing R-22 systems can keep running on reclaimed and previously produced refrigerant, but EPA cautions that price and availability may change ². When an R-22 system needs a refrigerant-related repair, quote the repair and a replacement side by side and let the owner choose.

Example: Suppose you have 300 members with both heating and cooling: 300 visits in spring and 300 in fall. If one tech completes 6 tune-ups a day, each season takes 50 tech-days. Fit the spring visits into 8 weeks (40 workdays) and you need 1.25 techs doing nothing but tune-ups. Run this math before you sell more agreements, and start booking early enough to finish before the first heat wave.

Run tune-up campaigns before the rush

Timing is the campaign. ENERGY STAR tells homeowners to have the cooling system checked in spring and the heating system in fall because contractors get busy once summer and winter arrive, and suggests planning check-ups around the spring and fall clock changes ¹. That gives you two natural send dates a year and a message customers may already have heard from a neutral source.

Work your list in this order:

1. Members. Book every agreement customer before you open the calendar to anyone else.
2. Past customers without an agreement. Anyone you've repaired or installed for is a warm lead. The tune-up gets you back in the house, and the visit is your chance to offer the agreement.
3. New customers. Your website, Google profile and referral partners fill the remaining slots.

Match the message to the season. In spring, sell the cooling check before the first hot week: coils, condensate drain, electrical connections. In fall, lead with safety and reliability. ENERGY STAR notes that improperly operating gas or oil connections are a fire hazard and can contribute to health problems, which is why the heating check-up covers connections, gas pressure, burner combustion and the heat exchanger ¹. Promise what the visit includes, not energy savings you can't back up.

The HVAC seasonal playbook covers the rest of the year: staffing, inventory and what to focus on each month.

Set up your Google Business Profile as a service-area business

Most HVAC work happens at the customer's home, which makes you a service-area business in Google's terms. Google says that if you don't serve customers at your business address, you should remove it from your profile; its example is a plumber who runs the business from a home address ³. The same applies to an HVAC shop run from a house or a yard customers never visit: clear the address and set a service area instead.

You can list up to 20 service areas by city, postal code or other area, and Google says the overall area shouldn't extend more than about 2 hours of driving time from where your business is based ³. Treat that as a ceiling, not a target. Draw the area around the places you can reach on a no-heat call the same day; a sprawling area fills July with drive time and leaves customers waiting.

While you're in the profile:

• Choose categories and write a description that say heating and cooling plainly, in the words people search: AC repair, furnace repair, heat pump installation, tune-ups.
• Keep hours accurate. If you show emergency or after-hours availability, someone has to answer those calls.
• Ask for reviews at the moments HVAC work creates: a tune-up that caught a problem early, a system brought back on a hot night. Follow the rules in how to get more reviews legally before you ask.

Decide whether Local Services Ads pay for themselves

Local Services Ads are Google's ads for local service businesses. Before you budget for them, know three things.

The badge has a new name. Since October 20, 2025, Google has used a single Google Verified badge in place of the older Google Guaranteed, Google Screened and License Verified by Google labels ⁴. The money-back guarantee tied to the old Google Guarantee badge has been discontinued ^{4 5}. If your website, truck wrap or estimate template still says "Google Guaranteed," update it, and don't tell customers Google will reimburse them for your work.

Screening covers your whole field team. Every business has to pass Google's screening and verification, which varies by category and location and can include background, business registration, insurance and license checks, plus minimum review requirements. Where your category and location require background checks, they cover all owners and every employee, independent contractor or other worker who will perform core services for the customer. Where a category requires insurance, you submit a certificate of insurance, with the minimum amount set by category and location. Google verifies state-level licenses where it can, and you must confirm that you hold any required county or city licenses and that every technician is appropriately licensed ^{6 7}. In practice, start a new tech's background check on their first day so you can send them to ad leads as soon as they're ready.

The buying model is moving. Google's help center now describes a transition of Local Services Ads to Performance Max campaigns with pay-per-lead goals ⁸, so expect setup screens and options that differ from older tutorials.

Whatever the screens look like, you're paying for leads, so judge the channel by cost per booked job, not cost per lead.

Example: Say you spend $1,500 in a month and get 30 leads, so each lead costs $50. Your office books 12 of them and your techs turn 10 into paying jobs. Your cost per new customer is $1,500 ÷ 10 = $150. If those jobs average $250 in gross profit and a few of the customers join your maintenance agreement, the ads are paying their way. If most leads never answer a callback, they aren't, however cheap each lead looks.

Tag every lead with its source so you can compare that number across ads, your Google profile, referral partners and repeat customers. Customer acquisition cost walks through the calculation.

Build referral partners who send repeat work

Property managers and real estate agents both send HVAC work again and again, but each needs something different from you.

Property managers

A property manager responsible for dozens of units can become a steady source of work, as long as you make their job easier:

• Speed on no-heat and no-cool calls. Tenants call the manager, the manager calls you, and your response time becomes their reputation.
• A pre-approved repair limit. Agree on a dollar amount your tech can approve on the spot and a process for anything above it, so a unit isn't left down while you wait on a callback.
• Records per unit. Photos, a short written finding and an invoice that names the property and unit, so the manager can bill the owner without calling you.
• One agreement for the portfolio. Scheduled filter changes and tune-ups for every unit, timed around move-outs where possible, turn a stream of emergencies into planned work.

Real estate agents

Home sales create HVAC work at three points: before listing, when a seller wants no surprises; during the buyer's inspection, when the furnace or AC gets flagged and everyone is on a deadline; and after closing, when new owners know nothing about the system's history. Agents need a contractor who can get out within the inspection window, write a clear report with photos and the system's age and condition, and price both the repair and the replacement. Keep your findings neutral. An agent keeps calling the contractor whose reports hold up for both sides of the deal.

New owners you meet this way make strong agreement prospects: they may not have an HVAC company yet, and they don't know the system's history. Offer the agreement at the first visit.

Be ready when heat waves and cold snaps hit

Heat waves and cold snaps bring calls from people who have never used you, including customers whose usual company is booked and people who never had one. The company that answers gets the job and a shot at keeping the customer.

• Answer every call. During a cold snap, a missed call goes to the next company on the list. Set up overflow answering or an on-call rotation before the season, not during it.
• Triage by risk. Ask whether anyone in the home is elderly, an infant or medically fragile, and move those calls up. For any report of a gas smell, follow your gas utility's emergency guidance before scheduling anything.
• Try the easy checks by phone. Walking a caller through the thermostat setting and the breaker panel sometimes solves the problem. You lose a ticket and earn a customer with a reason to call you first next time.
• Give honest arrival windows. A realistic window and a text when it changes beat a promise you can't keep.
• Protect member priority. If your agreement promises priority service, hold capacity each day for members so the promise means something.
• Stock from history. Pull last summer's and last winter's parts usage and load trucks with what you replaced most.

When the rush ends, follow up with every emergency customer: a thank-you, a review request and an offer to join your agreement before the next season. That's how a one-time emergency becomes a member.

Follow up on every replacement quote

Replacement quotes are among the largest tickets you write, so treat each open one as unfinished work until the customer says yes or no. HVAC replacements come in two kinds, and each needs a different follow-up:

In each follow-up, answer the questions people think of after you leave: why you sized the system the way you did, what the efficiency difference between options means for them, what the warranty covers and how long installation takes. Lay the options out so they're easy to compare; how to write an HVAC estimate covers the format. If you mention a utility rebate or tax credit, confirm it on the program's own site first and present it as conditional on the customer qualifying.

For the cadence and what to say at each touch, use how to follow up on quotes. Whatever you track quotes in, from a spreadsheet to chat-first field service software like Redline, every open replacement quote needs a next follow-up date and a person responsible for it. A planned replacement that stalls in the fall can come back to life in spring, when the old system has to carry the house through the heat again.

Track what each channel brings in

Review these numbers monthly and move time and money toward the channels that produce members and replacement jobs, not just calls.
