What if I have more than one HVAC system?

Each system gets its own measured evaluation and its own Home Comfort Report. The first system is $249, and each additional system evaluated the same visit is $149, since we are already on site.

Why pay for an evaluation when other companies come out at no charge?

Because a no-cost visit is a sales appointment. The technician's hour gets paid for by whatever you buy at the end of it. Charging for the diagnostic keeps the recommendation independent of the sale, the same way your doctor and your mechanic charge for diagnosis.

What if nothing turns out to be wrong?

Then the Home Comfort Report says so, with the measurements to prove it. That is worth knowing before someone else talks you into a repair you don't need.

I already paid the $99 service call. Does it count toward the evaluation?

In full. The $99 credits toward the $249, so you pay the difference rather than both. That's true whether you upgrade on the spot or book the evaluation later.

I've already been told I need a new system. Is an evaluation still worth it?

It is a measured second opinion before you spend thousands of dollars. We measure what your current system is actually doing and tell you whether replacement is warranted, with the numbers to back it up.

SystemIQ Evaluation

$249

The SystemIQ Evaluation. Find out what your AC is actually doing.

A 1–2 hour, instrument-based assessment of how your system actually performs, total airflow measured with a TrueFlow grid, ending in a Home Comfort Report you keep. A paid evaluation that measures what's wrong instead of guessing at it.

What the evaluation buys

Everything you walk away with.

Total system airflow, measured with a TrueFlow grid. This is the work that sets the price, and almost nobody else does it
Static pressure profile, the sixty-second reading most companies never take
Refrigerant charge verified against measured superheat and subcooling, in cooling season when the readings mean something
Combustion analysis and carbon monoxide readings on gas equipment, in heating season when the furnace is doing its real work
Temperature splits that show what the equipment is actually delivering
Your Home Comfort Report, with every reading in plain language, a prioritized plan, and what each fix should cost

A replacement system runs $8,000 to $15,000. This is the measured data that decision should be based on.

The credit: Started with the $99 service call? It credits toward the $249 in full. You pay the difference, never for the same visit twice.

What's included

We spend an hour or two with your system and your house, and we measure the things that determine comfort and efficiency: static pressure, total system airflow, temperature split, refrigerant charge in cooling season, and combustion on gas equipment in heating season. We test what the season lets us test honestly, and the report says exactly what was measured.

Nothing here is a checklist of filters and a sticker on the unit. Every number is recorded, and every number means something for how your home feels and what it costs to run.

Static pressure, the measurement most companies skip

Static pressure is the blood pressure of your AC system. Equipment is designed to run against a specific resistance, usually about 0.50″ wc on a residential air handler. When the reading comes in higher, the duct system is fighting the equipment. Airflow drops, efficiency goes with it, and the compressor runs hot. It takes sixty seconds to measure and most technicians never do it.

If your house feels uneven or your bills are climbing, this single reading often explains why.

Airflow, refrigerant, and combustion

The TrueFlow grid measures how much air your system is actually moving, which is frequently nothing like what the equipment was built to deliver. In cooling season, manifold gauges and measured superheat and subcooling tell us whether the refrigerant charge is right; a charge reading taken in cold weather isn't one worth paying for. In heating season on gas equipment, a combustion analyzer reads efficiency and the safety numbers, carbon monoxide included, that nobody should be eyeballing.

Why pay for a diagnostic at all?

Fair question. Most companies will come look at your system at no charge, but be clear about what that visit is. It is a sales appointment. The technician's hour gets paid for either way, and on a no-cost visit it gets paid for by whatever you buy at the end of it. The recommendation has a quota standing behind it.

Your doctor charges for the exam. Your mechanic charges for the diagnostic hour. That isn't greed. It is what keeps the diagnosis independent of the sale. The SystemIQ Evaluation works the same way. You are paying for measurement and a written answer, and the answer is yours whether you hire us for the work or not.

And if your system is simply broken, you don't have to start here. The $99 service call diagnoses the problem you called about, and if the answer points to a bigger question, the $99 credits toward this evaluation.

Your Home Comfort Report

You finish the evaluation with the Home Comfort Report. It has every measurement we took, written in plain language, what those readings mean for how your house feels and what it costs to run, and what is worth doing about it in priority order with real costs. There is no pressure and no upsell. The report is yours whether you hire us for the work or not.

Who should book one

Homeowners with rooms that never feel right, bills that keep climbing, a system that short-cycles, or a house that stays humid in summer. Anyone considering a repair-or-replace decision who wants real data first. And anyone who has been told to replace a system and wants a measured second opinion before spending thousands of dollars.
