Just had a new system installed? Let’s make sure it was actually done right.
Passing a city inspection means the install is safe and legal. It doesn’t mean the airflow was ever measured, the ductwork was sealed and sized right, or the workmanship matches manufacturer spec. We check what the permit doesn’t — and since we don’t sell new systems, we have nothing to gain either way.
The numbers a permit doesn’t cover
Everything gets measured and written down — not eyeballed.
Airflow & static pressure
The actual CFM and static pressure your system is moving — the single biggest factor in comfort and equipment life.
Electrical & amp draws
Capacitors, contactors, and connections checked and measured, not just visually inspected.
Combustion safety (furnaces)
A CO safety test and a real look at venting and clearances — not just “it lights.”
Gas pressure
Verified against manufacturer spec on non-modulating furnaces. Fully modulating gas valves adjust electronically and can’t be manually checked the same way.
Ductwork & connections
Sealed properly at the plenum and takeoffs, sized right, and not choking the airflow you’re paying for.
Condensate & drain trap
Proper slope, a working trap, and no shortcuts that lead to a leak down the road.
Surge protection & overflow switch
Two cheap parts a lot of installers skip on new equipment. If they’re missing, we’ll tell you — and can add them.
Refrigerant charge check
Verified by the numbers, not a gauge — bring your owner’s manual and ask your installer exactly how much they charged, and we’ll confirm it against spec.
Code & manufacturer clearances
Permit compliance is the floor, not the ceiling — we check against what the manufacturer actually requires.
We have nothing to gain either way
Most companies that offer a “free online second opinion” sell new systems — which means their opinion comes with an incentive baked in. We don’t sell or install new furnaces, ACs, or heat pumps. We’re not evaluating your install so we can pitch you a different brand or talk you into a bigger system. We measure what’s there, write it down, and hand it to you.
If everything checks out, great — you get real numbers proving it. If something’s off, you’ll know exactly what and why, in writing — instead of just a bad feeling you can’t put into words. We can’t promise your installer will act on it (most workmanship warranties only run through their own process), but you won’t be guessing anymore.
- A written System Health ReportThe actual measured numbers, in plain English, that you keep.
- No new-system sales pitchWe don’t sell new systems, so there’s no incentive to talk you into a different one.
- Missing safety parts flaggedSurge protection and an overflow switch are cheap, and a lot of installers skip them. We’ll tell you if yours are missing and can add them.
- Straight answersIf it’s right, we’ll tell you. If it’s not, we’ll show you exactly what and why.
Post-install inspection questions
My new system already passed the city inspection — why would I need another one?
A permit inspection checks that the installation is safe and legal to sign off on — it does not verify the airflow was ever measured, the ductwork was sealed and sized right, or the system is actually running the way the manufacturer designed it to. Those are performance details, not code details, and they’re exactly what determine whether your system runs efficiently and lasts.
Do you sell new systems, or try to talk me into a replacement?
No. We don’t sell or install new systems, so a post-install inspection from us has zero incentive attached to it — we’re not trying to win the install, and we’re not trying to talk you into a different one. We just tell you what we measure.
What do you check during a post-install inspection?
Airflow and static pressure, electrical connections and amp draws, combustion safety and venting (furnaces), gas pressure where the equipment allows, ductwork connections, condensate drainage, whether surge protection and an overflow switch were installed, refrigerant charge documentation, and general workmanship against code and manufacturer clearances. You get the actual numbers in a System Health Report.
Can you verify my gas pressure?
Yes, if your furnace isn’t fully modulating — we’ll check it against manufacturer spec with a manometer. Fully modulating gas valves adjust electronically and can’t be manually verified the same way; we’ll let you know if that’s the case with your equipment.
Can you verify my refrigerant charge?
Not with a gauge — modern systems need an exact factory charge, and guessing at it in the field can do more harm than good. What we can do: if you have your owner’s manual and ask your installer exactly how much refrigerant they charged, we’ll verify that number against what the manufacturer specifies for your line set length.
Do you check for surge protection and an overflow switch?
Yes — these are two inexpensive parts that protect your new equipment, and we see them skipped on a lot of installs. If yours are missing, we’ll tell you, and we can add them.
If something wasn’t done right, will the installer fix it?
That’s between you and them, and we can’t promise they’ll act on findings from a company they didn’t hire — most installers only honor their workmanship warranty through their own process. What we can do is give you an honest, independent read on what’s actually there, in writing, so you’re not just taking someone’s word for it.
How much does a post-install inspection cost?
$160, flat and upfront. Want a full Manual J load calculation too? That’s a separate service, $240, and can be booked together.

Whether it was installed last week or last year, we’ll check it against the numbers that actually matter — no sales pitch attached.
