Keeping replacement estimates coming in through the slow season.

Every HVAC company has shoulder seasons, when the weather is mild and the phone goes quiet. Your crews, your trucks and your payroll don’t take that time off. The companies that stay steady through it don’t wait for the phone to ring. Here are five things to do about it, starting with the cheapest.

1. Go back to the estimates you already ran

Your unsold estimates from the last twelve months are the warmest list you have. These homeowners already let you into their home and already know their system is on borrowed time. Many didn’t say no; they said “not yet.”

Call them. Ask how the system has been running and whether anything has changed. Keep it short and helpful, not pushy. Some of them are now ready, and they’d rather buy from the company that already came out than start over.

2. Call maintenance customers with aging systems

Your maintenance list tells you who has an older system and when it was last serviced. A friendly call to check in, before the season turns, puts you first in line when they decide to replace instead of repair again.

3. Ask every install customer for a review and a referral

The best time to ask is right after the install, while the house is comfortable and the crew made a good impression. A review helps the next homeowner choose you. A referral to a neighbor with the same age of home is often the warmest lead you’ll get all month.

4. Answer new leads in minutes, not hours

When fewer people are calling, every inquiry matters more. A homeowner who fills in a form usually contacts more than one company, and the first one to call back has the best shot at the estimate. Make a fast callback the rule, not something that happens when someone has a free moment.

5. Don’t go dark on advertising

It’s tempting to cut marketing the moment things slow down. But the homeowners who still need a new system don’t stop needing one. Keep showing up where they look, and make sure every lead gets a call and a clear next step.
