Facebook ads for HVAC companies in San Diego have to deal with a strange fact: half the county barely needs air conditioning and the other half cannot live without it. Someone in Ocean Beach runs a fan in August; someone in El Cajon runs the AC from May through October and pays SDG&E for the privilege. Your Meta campaigns should be split along that line before anything else, and this guide walks through how.
Coastal versus inland is the whole strategy
Draw a rough line along the 805 and the 15. West of it, HVAC demand is about heat pumps, mini-splits for ADUs and additions, indoor air quality, and replacing an old furnace that only runs in January. East of it, demand is about AC replacement, high-efficiency systems that cut a $500 summer bill, duct work in older tracts, and emergency repair in a heat wave. Build two campaigns:
Inland ad sets: El Cajon, Santee, Lakeside, La Mesa, Spring Valley, Escondido, San Marcos, Vista, Poway, Rancho Bernardo, Ramona, Eastlake, Otay Ranch. Homeowners 30 and up, creative focused on AC, bills, and heat.
Coastal and central ad sets: La Jolla, Pacific Beach, Point Loma, North Park, Carmel Valley, Encinitas, Carlsbad. Creative focused on heat pumps, mini-splits, ADUs, air quality, and quiet systems.
Heat pumps and the ADU boom
California is pushing electrification hard, rebates for heat pumps come and go, and San Diego is building ADUs faster than almost anywhere. Every ADU needs a mini-split or a small heat pump system and the owner is usually a first-time landlord who has no idea who to call. A Meta ad that says "building an ADU in Clairemont or North Park? Here is what a mini-split costs installed" hits a real, underserved audience. Target homeowners with home-improvement interests in the neighborhoods with the most ADU permits: Clairemont, North Park, City Heights, Encanto, Chula Vista, La Mesa, Escondido.
Seasonal timing for this county
- April and May: pre-summer tune-up offers. Cheap to run, good for building a maintenance-plan list.
- June Gloom: coastal demand is dead; inland is warming up. Shift budget east.
- August through October: the real heat, including Santa Ana events. Inland replacement and repair demand peaks. This is when Meta retargeting of your website visitors pays off most.
- November and December: furnace and heat pump season, mostly inland and in the older coastal housing stock. Smaller than summer but less competitive.
- January through March: quiet. Good time for financing offers and indoor air quality messaging.
Creative that works
HVAC is a category where a plain video of your tech explaining something honest beats any produced ad. "This is a 22-year-old condenser in a Santee backyard. Here is why the electric bill is $400." A real bill comparison after an efficiency upgrade, with the customer's permission. A photo of a mini-split in a finished ADU. An offer with a real number: tune-up price, replacement starting price, financing terms. Do not run generic stock photos of a smiling technician; every competitor already does and nobody believes them. Mention the actual neighborhood in the text; "serving Rancho Bernardo, Poway, and 4S Ranch" gets more clicks than "serving San Diego."
Offers and the maintenance plan
The best long-term use of Meta for HVAC is building a maintenance plan base. A $99-a-year plan with priority service during heat waves, promoted to inland homeowners in April, is a cheap lead to acquire and turns into a replacement customer in three years. Lead form campaigns for tune-ups typically run $15 to $50 per lead in San Diego. Replacement and heat pump lead campaigns run higher, roughly $50 to $150 per lead, with quality varying a lot based on your qualifying questions. Retargeting website visitors from your Google campaigns is the cheapest source in the account and should always be running.
Budget and what to expect
A single-market HVAC company should plan on $1,000 to $3,000 a month on Meta alongside a Google Search campaign that handles the emergency traffic. Meta leads are softer than search leads: more questions, more "just looking," more no-shows. Fast follow-up (minutes, not hours) is the difference between a good campaign and a bad one, and your dispatcher matters as much as your ads.

Management and fair fees
For $1,000 to $3,000 in monthly Meta spend, a fair management fee is $500 to $1,200, more if it is bundled with Google Search management and creative production. The manager should be shifting budget between inland and coastal ad sets with the weather, not running a static campaign.

Facebook ads for HVAC companies in San Diego come down to knowing which side of the 15 your customer lives on and what month it is. Split the campaigns, follow the heat, and build the maintenance list while it is cheap.
