HVAC lead list calculator
For heating and cooling companies that call or text tune-up reminders, maintenance-plan renewals and old quotes: estimate how much of a list is reachable, and what the dead numbers cost your team on every campaign. Every rate is editable; nothing is stored.
Why HVAC customer lists go bad
- Customers serviced years ago stay in the system while they change numbers or sell the house.
- Web form and ad leads can carry a fake or mistyped number from someone who only wanted a price.
- Numbers taken over the phone or written on a paper invoice are easy to get one digit wrong when typed in later.
- Purchased or shared lead lists can include numbers that were already dead when you received them.
How to get your real numbers
- Pull a random sample of 500 to 1,000 numbers from your tune-up, maintenance-plan or old-quote list.
- Validate it against live carrier data with TrueSearch for Business.
- Enter the dead, landline and VoIP percentages you get back above.
- Repeat per list (past customers, open quotes, bought leads) to see which one holds the most bad numbers.
Read about phone list cleaning, check allowed hours with the calling hours checker, remove repeats with the duplicate lead remover, or check single numbers with the carrier lookup.

Are the default rates typical for HVAC customer lists?
No. They are editable placeholders, not industry statistics. Bad-number rates depend on where the records came from and how old they are. Validate a sample of your own list and enter what you find.
Can I clean an export from our HVAC service software?
Yes, if it exports to CSV or Excel. Upload the file to TrueSearch for Business and download it back with each number marked valid or dead, with its line type (mobile, landline, VoIP or toll-free) and carrier.
Do landlines matter on a homeowner list?
Yes, in a different way for calls and texts. A home landline can still be the right number for a phone call, so do not delete it just for being a landline. Standard landlines cannot receive SMS, so they should come out of a text reminder send.
Should I re-check the list before each tune-up season?
It helps. Numbers change over time, so customers you last serviced years ago will usually have more dead numbers than last month's service calls. Re-checking before a spring or fall campaign shows you how many are still reachable.
Does a valid result mean the customer agreed to be called or texted?
No. Validation checks the phone number, not consent. A customer who booked a repair once has not necessarily agreed to marketing calls or texts later, and purchased leads carry their own consent questions. Confirm your program with counsel.
Does this check consent or Do Not Call lists?
No. The calculator only estimates reachability, and a validation check covers validity, line type and carrier. It does not verify consent or check a number against Do Not Call or litigator lists. Keep your own opt-out records and use the official National Do Not Call Registry (donotcall.gov) where it applies.
This guide is general information, not legal advice. TrueSearch for Business checks validity, line type and carrier from licensed telecom data. It does not check the National Do Not Call Registry, state DNC lists or the FCC Reassigned Numbers Database. Not a consumer reporting agency; not for FCRA purposes.
