Expert Heating & Cooling Solutions for Green Bay

Comfort in Green Bay shouldn't depend on the season. Wausau HVAC keeps local homes and businesses at the right temperature year-round with responsive, experienced heating and cooling service, from same-day AC repair to right-sized system replacements. We've worked in nearly every neighborhood in the area, which means we've seen how these systems fail locally and we arrive prepared, with the common failure parts already on board. Call (920) 516-9397 and we'll get the fix started.

Heating and Air Conditioning Service Across Green Bay

Whether you own a single-family home, a rental property, or a commercial space in town, we have the expertise and equipment to handle the full range of heating and cooling work. Our technicians bring years of hands-on experience with central air conditioners, gas and electric furnaces, heat pumps, and ductless mini-splits throughout the area, and we pay close attention to the climate patterns, housing stock, and local code requirements that shape how systems perform in this area.

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 instead of a rule of thumb, so you get even temperatures and reasonable utility bills instead of a unit that short-cycles itself to an early death. Seasonal maintenance visits clean coils, verify refrigerant charge, test safety controls, and check static pressure, still the most reliable way to extend equipment life.

Commercial work is a big part of what we do too. We service rooftop units, split systems, and ventilation equipment for restaurant kitchens, shops, offices, and multi-unit properties, knowing that a day without cooling costs the business. To keep that downtime short, we carry common parts on every truck, diagnose fast, and schedule larger jobs around your operating hours whenever possible.

Fast HVAC Response in Green Bay

Call us about a problem and a real person answers, not a phone tree. Most calls get scheduled the same day or the next, and urgent calls, an AC that quits in a heat wave or a furnace that fails on a bitter night, jump to the top of the schedule. Scheduling stays flexible so nobody is stuck waiting for a callback.

The emergency calls we run tend to follow a pattern. On the cooling side, it's warm air from the vents, an outdoor unit that hums without starting, or an evaporator coil frozen solid. On the heating side, it's a furnace that lights and then shuts down. Year-round, it's breakers that trip whenever the system starts, clogged condensate drains backing water into the furnace cabinet, and thermostats that have quit. Because our trucks carry capacitors, contactors, igniters, flame sensors, universal control boards, and fittings, most of these get fixed on the first trip, with the price agreed before any work begins.

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 strain the compressor. If a furnace is short-cycling or you smell something burning, shut it down at the switch and call (920) 516-9397. A few minutes of caution can prevent a much larger repair.

Getting More Years From Your HVAC System in Green Bay

The best way to avoid a mid-season breakdown is routine maintenance. We recommend that homeowners replace filters every one to three months, keep vegetation trimmed two feet back from the outdoor condenser, rinse the condenser coil each spring, and have a professional tune-up twice a year, cooling in spring and heating in fall, so small problems get caught while they're still inexpensive.

Age matters too. Most central air conditioners run 12 to 15 years, furnaces 15 to 20, and heat pumps 10 to 15 with regular service. If your system is past that window and starting to struggle, such as climbing utility bills, rooms that never quite reach temperature, or a service call every season, a planned replacement is almost always cheaper and far less stressful than an emergency one in the middle of a cold snap.

Small problems rarely stay small for long. Take a weak capacitor: replacing it is a quick, inexpensive repair, but if it's ignored for a season, it can burn out the compressor, and suddenly a minor fix has become a full system replacement. That's why we ask homeowners to keep our number in their phone and call at the first hint of trouble. Catching it early saves time and money and spares you a miserable night.

Common HVAC Problems in Green Bay

Ask any homeowner around here what HVAC trouble looks like and the answers sound familiar: the upstairs that never cools, the furnace that woke everyone up with a loud bang at 2am, the system that runs all day but never satisfies the thermostat. Behind those stories are predictable culprits: worn capacitors and contactors, low refrigerant charge, undersized returns, and years of skipped maintenance. Our technicians see these problems weekly and carry the parts to fix most of them on the first trip.

Why Green Bay Residents Choose Us

Wausau HVAC treats this community like our own backyard, because it is. We show up when we say we will, we diagnose before we quote, and we put real numbers on both repair and replacement so you can decide with facts instead of pressure. Our technicians are experienced across every major brand, our trucks carry the parts that actually fail, and our work is checked in every mode before we go. That's why neighbors here pass our number around.

Your HVAC Questions Answered

It comes down to age and which part failed. Under about 10 years, most component failures are worth fixing. Past 15 years, or any time a compressor or heat exchanger fails, replacement is usually the smarter money, especially given how much more efficient new equipment is. We give you both numbers straight and let you make the call. We'd rather earn your trust than sell you a system before you need one.
It depends on what's wrong. Repairs usually come in between $150 and $650, based on the part that failed and the type of system. A complete system replacement generally costs around $5,000 to $12,000 installed, depending on size and efficiency rating. Before any work starts, you'll get a clear quote based on the diagnostic, and that price holds.
For a lot of homes, yes. Ductless mini-splits work especially well in room additions, garages, sunrooms, and older homes that never had ducts. The process starts with sizing each zone for the real load of that room, followed by thoughtful placement of the indoor and outdoor units and a clean install of the line set, condensate drainage, and electrical connections. If central equipment is the better choice for your layout, we'll tell you.
Fast. We cover the whole area with same-day appointments for most calls, and no-heat and no-AC calls get top priority. Our trucks are stocked with the most frequently needed parts, including capacitors, contactors, igniters, and motors, so the majority of repairs are diagnosed and completed in a single visit. Call (920) 516-9397 and we'll give you an honest arrival window.
All major brands, including Carrier, Trane, Lennox, Rheem, Goodman, and York, plus ductless systems from Mitsubishi, Fujitsu, and LG. Our technicians carry universal parts that fit most units and can source brand-specific components quickly when a repair calls for them.
We do offer twice-a-year maintenance across the area. The spring visit focuses on cooling: coil cleaning, a refrigerant charge check, capacitor testing, and airflow readings. The fall visit covers heating: cleaning the burners, checking combustion, and testing every safety control. Staying on that schedule adds years to your equipment, helps prevent breakdowns during the worst weather of the year, and usually pays for itself in energy savings.
First, rule out the easy stuff. Confirm the thermostat is in cooling mode and the batteries aren't dead, swap the filter if it's dirty, and check the breakers for the indoor and outdoor units. Ice on the copper lines or an outdoor unit that hums without running means it's time to shut the system off, since running it can damage the compressor. Call us at (920) 516-9397 and we'll send a technician your way without delay.
Both. Most visits begin as a repair, and our technicians work on air conditioners, furnaces, heat pumps, and ductless mini-splits from every major brand. When repair no longer makes sense, we manage the whole replacement, from the load calculation and hauling off the old unit to installation and testing in every mode. Whichever way it goes, you'll see clear pricing for each option before you decide.
