Trusted Green Bay HVAC Service
When you need a dependable heating and cooling company in Green Bay, Sheboygan HVAC is the company to call. We've been keeping local homes and businesses comfortable year after year, earning repeat business one job at a time. Our technicians are local, not dispatched from across the state, which means shorter waits and a real understanding of the climate patterns, housing stock, and ductwork quirks that shape how HVAC systems here perform and fail.
From a single furnace that won't light to complete system replacements, ductless mini-split installations, and seasonal maintenance programs, our team takes on every type of residential and commercial heating and cooling need. We offer prompt service and give you upfront pricing before any work begins, no hidden fees, ever. Our trucks carry the parts that fail most, capacitors, contactors, igniters, flame sensors, blower motors, and thermostats, so most repairs are finished in a single visit.
Whether your air conditioner is blowing warm air, your furnace is clicking but never lighting, or you're simply planning ahead for a system past its prime, one call to (920) 516-9347 gets an experienced local technician headed your way with everything needed to diagnose the problem quickly.

Complete Heating & Cooling Services for Green Bay Properties
We service every type of heating and cooling equipment you'll find in local homes and businesses, from central air conditioners and gas furnaces to heat pumps and ductless mini-splits. It makes no difference whether the building is a starter home, a townhome, or a busy office. Our technicians understand the local weather, the age and construction of local homes, and the code requirements inspectors enforce, which pays off in the quality of every repair.
On the residential side, we take care of everything from quick fixes, like a weak capacitor, a pitted contactor, a dirty flame sensor, or a seized blower motor, to tracking down refrigerant leaks, complete system replacements, and ductless additions. Every new system we install is sized with a proper load calculation rather than guesswork, so you get even temperatures and reasonable utility bills instead of a unit that short-cycles itself to an early death. Our seasonal tune-ups clean coils, verify refrigerant charge, test safety controls, and check static pressure, still the most reliable way to extend equipment life.
For commercial property owners and managers nearby, we service the rooftop units, split systems, and makeup air and ventilation equipment that restaurants, shops, offices, and apartment buildings depend on. We understand that a hot dining room or a freezing office means lost business, so we prioritize fast diagnosis, carry common parts on the truck, and schedule work around your operating hours whenever we can.
When Your System Fails in Green Bay
If your heat or air quits, how quickly help shows up matters more than anything else. That's why we keep our schedule flexible across the area and answer every call with a live person. Emergency calls usually get a technician within a day, and we prioritize a failed furnace in a cold snap or a dead AC in the heat as top priority.
These are the problems that come up most when something breaks at home: an air conditioner blowing warm air, a condenser that hums but won't start, a furnace that lights for a few seconds and quits, a breaker that trips every time the system kicks on, an evaporator coil that has iced over, a condensate drain backed up into the furnace cabinet, or a thermostat that has gone blank. Nearly all of these come down to parts already on our trucks: capacitors, contactors, igniters, flame sensors, universal control boards, and standard fittings. You get the price before any work starts, with no surprises on the invoice.
If your AC has iced over, the most helpful thing you can do before we arrive is switch the system off at the thermostat and set the fan to "on" so the coil can thaw. Running it frozen can flood the drain pan and damage the compressor. If a furnace is short-cycling or you smell something burning, shut it down at the switch and call (920) 516-9347. A few minutes of caution can prevent a much larger repair.
How Green Bay Homeowners Can Extend HVAC Life
The best way to avoid a mid-season breakdown is routine maintenance. We recommend that homeowners replace filters every one to three months, keep shrubs and grass trimmed two feet back from the outdoor condenser, rinse the condenser coil each spring, and schedule a professional tune-up twice a year, cooling in spring and heating in fall, so small problems get caught while they're still inexpensive.
The age of your equipment matters just as much. With regular service, central air usually runs 12 to 15 years, a furnace 15 to 20, and a heat pump 10 to 15. Once a system passes that range and starts acting up, like rising energy bills, rooms that won't reach the setpoint, or one repair after another, it's smart to start planning a replacement. A planned replacement costs less and is far less stressful than an emergency swap during the worst heat wave of the year.
If comfort problems do show up, acting quickly keeps them small. A weak capacitor is a quick fix. The same capacitor left alone for a season can take the compressor with it and turn a minor repair into a full system replacement. It's smart to keep our number saved on your phone so you can reach us at the first sign of trouble. Early intervention saves time, money, and sleepless nights.
Comfort Challenges Green Bay Homeowners Face
HVAC systems in this area face a familiar set of enemies. Hard-running summers push compressors and capacitors to their limits, and humidity and airborne grit slowly foul outdoor condenser coils, cutting efficiency years before the equipment should show its age. Clogged filters quietly choke off airflow, freezing evaporator coils in summer and overheating furnace heat exchangers in winter, a slow kind of damage most homeowners never see coming.
We also see the full range of component failures in local homes: capacitors that leave the outdoor unit humming but not starting, contactors with pitted points, cracked igniters and dirty flame sensors that lock furnaces out on cold mornings, refrigerant leaks that turn into long lukewarm afternoons, and blower motors worn down by years of restricted airflow. The area's older housing stock adds its own layer, undersized returns, leaky or crushed ductwork, and additions that no duct run ever reached.
Every one of these problems is fixable, and most are much less expensive when caught early. If your system is doing anything unusual, new noises, weak airflow, rooms that won't hold temperature, bills creeping upward, a quick diagnostic visit from our team catches the small problem before it becomes an expensive one. Call (920) 516-9347 and we'll take a look.

Plenty of companies will sell you a new HVAC system. Sheboygan HVAC earns trust around here by fixing the ones that don't need replacing and being straight about the ones that do. We find the actual fault before we quote a dollar, explain your options in plain language with real numbers, and leave the decision to you. When replacement is the right call, we size the new system with a proper load calculation based on your home's real heating and cooling load, square footage, insulation, windows, and duct capacity, instead of defaulting to whatever's in the warehouse.
The workmanship holds up because we don't cut corners: correct refrigerant charge weighed in rather than guessed, sealed duct connections, proper condensate drainage, verified combustion and airflow on heating equipment, and clean electrical work that passes inspection without drama. We show up when we said we would, cover your floors, haul away the old equipment, and test the full system in every mode before we pack up. It's why so much of our local work comes from repeat customers and referrals, and why we back every job with a satisfaction guarantee.
