Whether it's a sudden breakdown or a planned efficiency upgrade, Green Bay HVAC has you covered with expert diagnosis, quality installs, and friendly, on-time service.
A broken AC or furnace doesn't wait, and neither should your service company. With technicians based around the Green Bay area, we provide fast, reliable service and hands-on care from experienced pros who know the climate and housing stock of our region.
Most of the calls we answer come down to two things: a house that won't cool, or a house that won't heat. Here's how we handle both.
When your AC hums but won't cool, blows warm air, or keeps tripping the breaker, the fix is usually a single worn component. We test the system, find it, and replace it, often the same day. Every repair comes with an upfront quote and an honest opinion on repair versus replacement.
Most furnace breakdowns come from a handful of parts: flame sensors, igniters, inducer motors, and control boards. We find the one that failed and fix it, usually in a single visit. Every visit includes a safety check of the burners and venting, and you'll know the price before we start.
We take on the full range of comfort problems, from failed capacitors and cracked heat exchangers to ductless installs and commercial rooftop units, with the hands-on experience the job calls for.
Warm air, frozen coils, or a unit that won't start, diagnosed and fixed right.

Call (920) 516-9298If something seems off with your comfort system, it usually comes down to one of these. Here are the problems we get called about most across Green Bay, and how we put a stop to each.
A system pushing warm air in summer is the call we run most. Our trucks carry capacitors, contactors, and motors to restore cooling same-day.
AC repairFrequent on-off cycling is the furnace protecting itself from a real problem. Ignoring it risks the heat exchanger, the most expensive part in the cabinet.
Furnace repairA system that runs constantly but never satisfies the thermostat is burning money. Seasonal maintenance restores the efficiency you paid for.
Maintenance & tune-upsR-22 refrigerant, rust on the cabinet, a compressor on its second capacitor, these are signs the smart money is on replacement.
System replacementYour ducts move the same air thousands of times a day. Years of dust, dander, and construction debris ride along until they're cleaned out.
Air duct cleaningWe size and mount mini-splits cleanly, proper line sets, condensate handling, and a tidy exterior finish, so they work as good as they look.
Mini-split installationA house at 90 degrees is an every-hour problem, so we treat it like one. Same-day appointments across Green Bay, with evenings and weekends available.
Every technician has years of hands-on HVAC experience across air conditioners, furnaces, heat pumps, and ductless systems, and trains continually on new models and refrigerants. Your home gets a specialist, not a generalist with a parts catalog.
If a $40 capacitor fixes it, that's what we'll tell you. We quote repair and replacement honestly, with real numbers, and let you choose, no scare tactics, no pressure.
A proper repair includes the details: static pressure check, capacitor test under load, combustion analysis on furnaces, and a clean condensate path that won't back up in August.
Year after year, Green Bay HVAC has been the team local families call when the AC quits or the furnace goes cold. We've serviced systems in nearly every neighborhood around town, and that track record shapes how we approach each job, from the first diagnostic to the final test.
Our team doesn't just swap parts and leave. We check the airflow, the charge, and the electrical supply driving the failure common to local homes and businesses. This local knowledge means faster diagnosis, fewer repeat visits, and systems that last.
Talk to someone who actually knows heating and cooling. Honest, no-pressure pricing over the phone.
We follow a proven, systematic approach to diagnose the problem, fix it right, and keep your home comfortable.
Ring (920) 516-9298 whenever it suits you. We'll talk through the symptoms, tell you if anything needs immediate attention, and lock in a visit time that fits your schedule.
We don't guess. The diagnostic covers the full system and turns into a straightforward recommendation with the cost spelled out up front.
Most repairs finish the same visit, our trucks carry the common parts. Replacements are installed to code with proper sizing, sealed connections, and clean workmanship.
We verify temperatures at the vents, check the charge, confirm the condensate drains clear, and walk you through what was done. Optional maintenance plans keep the system cleaned, inspected, and running efficiently for years.

There's no mystery to how we handle an urgent failure. Here's the step-by-step of what we do after a homeowner calls for fast help.
Our team answers your call promptly, gathers key details, cooling or heating, running or dead, any error codes on the thermostat, and books your visit, often same-day. We'll walk you through the quick checks worth trying first in the meantime.
Often within hours, our fully equipped technician is on-site with everything needed to diagnose and begin the repair in your property.
On the first appointment, we test the full system. Our technician checks the parts that fail most and explains what happened in plain language.
Seasonal maintenance runs on your schedule, so you never have to think about it, to clean coils and test components before they cost you a compressor. Staying ahead of the problem lasts years longer and runs cheaper every month.
"Years of dust, pet hair, and who knows what else came out of our ducts. After the cleaning, rooms that never got air finally do, and my wife's morning allergies have calmed way down. They showed us before-and-after photos of everything they pulled out."
"Our AC died on the hottest day of the year and a tech was out the same afternoon. He found a blown capacitor, swapped it from stock on the truck, and had cold air blowing in under an hour. Fair price, no drama, and he checked the rest of the system while he was there."
"Our restaurant's rooftop unit failed on a Friday with a full weekend of reservations booked. Their team got it running the same day. They clearly understood what downtime costs a Green Bay business, and they came back the next week to fully service the second unit. Customer for life."
We treat your home the way we'd treat our own: thoroughly, honestly, and with an eye on the long term. Here's the standard you can count on from us every time.
Hands-on experience is the real benchmark for HVAC work. Every technician on our team has years of field experience across air conditioners, furnaces, heat pumps, and ductless systems, ensuring your home is serviced according to proven best practices.
HVAC sizing is math, not guesswork, and we show ours. Our team calculates the right capacity for your home and installs it to local code, permits included where required.
We don't wait for failures to profit from them. Every maintenance visit is built around your system's age and condition. For hard-working systems, a $40 capacitor caught early can save a $2,000 compressor. Period.
