HVAC Marketing Calendar: What to Promote Every Month of the Year

Published 2025-05-31 · 7 min read

HVAC is one of the most seasonal trades. Summer and winter are slammed. Spring and fall can be painfully slow. The key to staying booked year-round is promoting the right services at the right time. Here is your month-by-month marketing calendar.

January — New Year Tune-Up Promotions

Start the year with a heating tune-up promotion. Homeowners are using their furnaces daily and many skipped maintenance in the fall. Push: “New year, new furnace filter — schedule your winter tune-up.” Also promote: carbon monoxide safety checks, thermostat upgrades.

February — Indoor Air Quality

Homes have been sealed up all winter. Indoor air quality is at its worst. Promote: air purifiers, duct cleaning, UV light installations, and humidity control. This is a great month for educational content about how poor air quality affects health.

March — Spring AC Tune-Up Campaign (Launch Now)

This is your biggest marketing month. Launch your spring AC tune-up campaign now so you are booked solid by April. Increase Google Ads budget by 30%. Run Facebook Ads targeting homeowners: “Beat the rush — schedule your AC tune-up before the summer wait.” Early bird pricing works well here.

April — AC Season Ramp-Up

AC tune-ups should be filling your schedule. Continue pushing tune-up promotions. Start promoting: AC replacements (“Is your system over 10 years old? Now is the best time to replace before summer.”), ductless mini-splits, and smart thermostat installations.

May — Last Chance Before Summer

Urgency messaging works: “Last call for tune-ups before the summer heat.” Switch Google Ads to emergency and repair keywords as broken AC calls start increasing. Promote: AC repair, emergency service, and new installations for systems that failed during their first use of the season.

June through August — Peak Season

You are probably fully booked. Shift marketing focus from acquiring new customers to:

Collecting reviews from every completed job (you are doing 3 to 5x normal volume — capitalize on it)
Reduce ad spend slightly if you cannot handle more calls
Post project photos daily on social media (content stockpile for slower months)
Promote maintenance agreements to one-time customers

September — Fall Transition

AC calls slow down. Launch your fall heating tune-up campaign: “Get your furnace ready before the first cold snap.” Promote: heating tune-ups, furnace inspections, heat pump maintenance. This is also a great time to push AC replacements at end-of-season pricing.

October — Heating Season Launch

Increase ad spend for heating keywords. Promote: furnace tune-ups, heating repairs, boiler maintenance, fireplace inspections. Content idea: “5 signs your furnace might not make it through this winter.”

November — Emergency Prep

First cold spells hit. Emergency heating calls increase. Make sure your Google Ads target emergency keywords: “furnace not working,” “no heat emergency,” “heater repair.” Promote: maintenance agreements as holiday gifts for homeowners (“Give the gift of a warm home”).

December — Year-End and Planning

Slower month for most markets. Use this time to: plan next year’s marketing calendar, film video content for the year, update your website. Offer year-end specials on maintenance agreements: “Lock in 2025 pricing — sign up for our maintenance plan before January 1.”

Pro Tip: The single most effective HVAC marketing strategy: maintenance agreements. A customer on a maintenance plan is worth 5 to 10x more than a one-time customer over their lifetime. Every marketing effort should ultimately drive customers toward a maintenance agreement.
