How Cold Email Filled This Shop's Pipeline

The Cold Email Approach

Most HVAC owners hate cold email. They imagine spammy messages that get deleted instantly. But when done right, cold email is one of the cheapest ways to fill your pipeline — especially for commercial and new-construction work.

A shop in San Antonio with 5 techs wanted to break into the property management segment. Apartments, offices, and retail spaces need regular HVAC service. But getting past the gatekeeper is hard.

How They Used CoolerDesk to Support Cold Email

They didn't use the chatbot for the cold outreach itself. Instead, they used their CoolerDesk site as the landing page for every cold email campaign.

Here's the flow:

1. Send a cold email to property managers in San Antonio

2. The email links to a specific landing page on their CoolerDesk site — not their homepage

3. The landing page is customized for commercial clients: maintenance plans, multi-unit pricing, response time SLAs

4. The chatbot on that page is tuned for commercial inquiries — it asks about square footage, number of units, and current HVAC vendor

5. Qualified leads are routed to the owner's SMS

The Numbers

Over 90 days, they sent 4 cold email campaigns to 340 property managers and facility directors.

| Metric | Value |

|---|---|

| Emails sent | 340 (4 campaigns) |

| Open rate | 38% |

| Click-through rate | 11% |

| Chat conversations started | 37 |

| Qualified commercial leads | 18 |

| Contracts signed (first 90 days) | 4 |

| Monthly recurring revenue from contracts | $3,200 |

What Made the Landing Page Work

The chatbot played a critical role in qualifying leads before the owner ever got involved:

• It answered the basic questions — service area, licensing, insurance requirements
• It collected property details — number of units, current HVAC vendor, contract renewal date
• It booked discovery calls — the owner only talked to prospects who were pre-qualified
• It followed up automatically — if someone left mid-conversation, the bot sent a follow-up email with a summary and the owner's direct number

The Cost Breakdown

• Cold email tool: $49/month
• CoolerDesk Pro plan: $99/month
• Landing page setup: 2 hours of owner's time
• Total monthly cost: $148
• Monthly recurring revenue from commercial contracts: $3,200 (and growing)

The commercial maintenance contracts have a 90% retention rate. Once you're in a building, you rarely get replaced unless you mess up.

The Owner's Perspective

> "Cold email alone wouldn't have worked. Nobody fills out a 'contact us' form from a cold email. But clicking a link and chatting with a bot? That's low friction. The bot did the qualifying work that I used to do on the phone."

The Takeaway

Cold email + chatbot landing page is a powerful combination for commercial HVAC growth. The email gets their attention. The bot closes the loop. The owner only talks to serious prospects.
