Honest Pricing, Explained Before We Start
Nobody likes calling for HVAC help and wondering if they’re about to get upsold. We keep it simple: you always know the price before any work starts, and the person quoting your job is a working technician, not a commissioned salesperson. We’ve priced our work this way from our Morgan Hill shop since 2009.
This is how the money actually works, start to finish.
The $110 Diagnostic, and Why It’s Fair
When something’s broken, a licensed technician comes to your home, tests the system, and finds the real fault. That visit is a flat $110, and it buys you a genuine diagnosis plus a written price for the fix. Move forward with the repair and that fee goes toward the work, and on larger jobs we waive it entirely. What you never get is a guess over the phone or a mystery number on the invoice.
Replacement Quotes Are Always Free
Thinking about a new system? The estimate’s free and there’s no obligation. A working installer walks your home, measures, photographs the space, and shows you exactly where the equipment, line set, and ductwork will go. The plan you’re shown is the plan you get.
What Repairs and Installs Typically Run
Every home and every fault is different, so we give you real numbers only after we see the system. As a rough guide, a typical repair runs about $761, and most land between $223 and $2,899. A common fix like a failed capacitor or contactor sits at the low end, while a compressor or a coil costs more. Full replacements vary with the equipment you choose and your home’s setup. Financing through Wisetack is available on qualifying work, and we’ll point you to any heat-pump rebates you qualify for before you spend a dime.
Repair or Replace? How to Tell
If your system’s under about ten years old and the fix is a few hundred dollars, repairing it almost always wins. Once it’s older, breaking down every summer, and the repairs start climbing into four figures, the math flips. A monthly payment on a new, efficient system often costs less than the breakdown treadmill on the old one, especially with rebates in play. We’ll tell you honestly which side of that line you’re on, and we’ve walked away from plenty of replacement sales when a cheap part was the smarter call. See financing if spreading the cost would help, or a maintenance plan to keep the system you have running longer.
The Value of Doing It Right
We’d rather pay a technician overtime to finish a job correctly than rush it and earn a callback. That’s why our reviewers so often mention fair pricing and no pressure in the same breath.

How Our Pricing Works
Diagnostic visit
A licensed technician comes out, finds the actual fault, and gives you a written price before any work begins. The fee covers the diagnosis, and it goes toward the repair when you move forward.
New-system estimate
Estimates on replacements and new installs are always free, with no obligation, and the person who quotes the job is a working installer, not a commissioned salesperson.
Maintenance plan
Two tune-ups a year, priority scheduling, member discounts on repairs and parts, and filter changes during your visits.
What Does HVAC Work Actually Cost in the South Bay?
These come straight from our own job records, parts and labor included. The first number is what a typical job costs. The range is where most jobs land. Your system and your home move it up or down, which is why you always get a written price before we start.
Service call
Most land between $110 and $284. That covers the $110 diagnostic plus the small fixes we can handle on the spot.
Repair
Most land between $223 and $2,899. It depends on the part, and you see the price in writing before we touch anything.
Tune-up
A one-off maintenance visit usually runs $129 to $324. On the plan, a whole year of visits costs less than that.
New system
Most installs land between $1,683 and $10,392, before rebates. The estimate is free, and we size it to your house.
What those numbers mean for you
- A year on our maintenance plan costs about 76% less than one typical repair.
- The plan’s two visits cost about 54% less than booking two tune-ups on your own.
- A typical repair costs about 85% less than replacing the whole system, so we’ll always tell you when a repair still makes sense.
- The $110 diagnostic is about a seventh of a typical repair, and it goes toward the fix when you go ahead.
Frequently Asked Questions
How much is a service call or diagnostic fee?
Our diagnostic fee is $110. It covers sending a licensed technician to find the actual problem and give you a written, upfront price, and it goes toward the repair when you approve the work. Estimates on new systems and replacements are always free.
Why do you charge for a repair diagnosis but not a replacement quote?
A replacement quote is a sales visit where we measure and design a new system, so it’s free. A repair diagnosis is skilled troubleshooting to find a specific fault, which is the work you’re paying a trained technician to do.
Will I know the price before work starts?
Yes, always. After the diagnosis you get an upfront price in writing, and nothing moves forward until you approve it. We never guess over the phone or add surprises to the invoice.
How much do repairs and new systems usually cost?
From our own job records, a typical repair runs about $761, and most land between $223 and $2,899 with parts and labor. A full system replacement typically runs about $4,951, with most between $1,683 and $10,392. We still won’t quote your job over the phone. You get a written price after we see the system.
Do you offer financing?
Yes. Modern Air offers financing through Wisetack so you can spread the cost of a new system or a major repair into monthly payments. Checking your options is a soft credit check that won’t affect your score.
