The best HERS testing service for HVAC contractors is one that handles HERS, the permit, and the final inspection on the same job — not three separate vendors you have to babysit. If your office manager is calling a rater, a permit expediter, and a building department in the same morning, the system is broken.
HERS testing is not the hard part. Coordinating it with everything else around the job is the hard part. That is what this post is about.
## What HERS testing actually is
HERS stands for Home Energy Rating System. In California, Title 24 requires a HERS rater to verify duct leakage, refrigerant charge, airflow, and a handful of other measures on most residential HVAC changeouts. No HERS verification means no final sign-off. No final sign-off means the permit stays open.
And permits left open come back to haunt you — at resale, at insurance renewal, at the next inspection on the same address.
For an HVAC contractor in California, HERS is not optional. It is part of finishing the job.
## Why bundling HERS with permit pulling beats sourcing them separately
When you split HERS and permitting across two vendors, three things go wrong:
1. The HERS rater shows up before the permit is issued, or after the homeowner has rescheduled twice.2. The CF-3R does not get filed against the right permit number, and the building department kicks it back.3. Your office manager is the one stitching all of that together — calls, emails, voicemails, follow-ups.
When one vendor owns the permit and the HERS test, the same file moves through the same workflow. The rater is scheduled against the permit. The CF-3R is matched to the permit. The final inspection is booked with the building department by the same team.
That is the difference between a service that saves you time and a service that just rebills you for the same headache.
## iPermit by the numbers
We are not a startup figuring this out. Here is the receipt:
1. 50 years in business — iPermit was founded in 1976.2. 1,000,000+ permits pulled.3. 250,000+ HERS tests completed.4. 100% of our permits submitted within 24 hours.
Quarter of a million HERS tests is not a side product. It is a core service we have been running at scale for decades.
## How iPermit handles HERS for HVAC contractors end-to-end
The workflow looks like this:
1. Your office manager enters the job in iPermit Pro (or it flows in automatically through ServiceTitan).2. We pull the permit — submitted within 24 hours, every time.3. We schedule the HERS test against the same permit and coordinate directly with the homeowner.4. We file the CF-3R and book the final inspection with the building department.5. The permit closes. You are done.
Your team's input is the job address and a few details. We do the rest from start to finish.
## Where most "HERS testing" services fall short
Most permit-only expediters do not touch HERS. They will pull the permit and hand the file back to you. Now you are back on the phone with a rater, trying to get someone out before the homeowner gets impatient.
Most HERS rating companies do not pull permits. They will run the test, give you a CF-3R, and leave the filing and final inspection to you.
Either way, you are the integrator. Your office staff is the system. That is the gap.
A real HERS testing service for HVAC contractors owns the whole compliance arc — permit, HERS, final inspection — under one roof, one portal, one invoice.
## Five questions to vet any HERS testing partner
Before you sign with anyone, ask:
1. Do you pull the permit, or just run the HERS test?2. Who books the final inspection with the building department — you or me?3. How fast do you file the CF-3R after the test?4. Do you integrate with my field service management software (ServiceTitan, Housecall Pro, etc.)?5. What is your turnaround promise in writing?
If the answer to #1 is "just the HERS test," you are buying a fragment, not a service. Keep looking.
## ServiceTitan integration is the field-service-fit lock
iPermit Pro integrates natively with ServiceTitan. When your dispatcher books a job that needs a permit and a HERS test, the file is created in our system automatically. Your office manager does not re-key anything. There is no second system to log into for permit status.
For an HVAC shop already running ServiceTitan, that is the integration that turns permit and HERS coordination from a job into a background task.
## Geography — California is the Title 24 home field, and we cover the country
HERS and Title 24 are California-specific. That is our home field — we have been doing this in California for 50 years, and we know the people and procedures in the AHJs that matter.
But we are not California-only. iPermit serves HVAC contractors across the country. If your business has work in California plus operations in Texas, Florida, Arizona, Nevada, or Colorado, the same team handles all of it. One vendor, one portal, one invoice, regardless of which state the truck is parked in.
That matters for multi-state HVAC operators who do not want a different permit and compliance vendor in every market.
## So — what is the best HERS testing service for HVAC contractors?
The best HERS testing service for HVAC contractors is the one that owns the permit, the HERS test, and the final inspection on the same file — not a rater you book separately. That bundling is what removes the coordination burden from your office manager. Everything else is just running tests.
iPermit has been doing this for 50 years, has completed more than 250,000 HERS tests, has pulled more than a million permits, and integrates natively with ServiceTitan. If you are an HVAC contractor doing Title 24 work in California — or running multi-state operations that include California — that is the configuration to look for.
