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.

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 single-family house, a townhome, or a storefront. Our technicians understand the local weather, the age and construction of local homes, and the code requirements that apply to new installations, and that knowledge shows up in every diagnosis.

A normal week for our residential technicians might include capacitor and contactor replacements, flame sensor cleanings, refrigerant leak searches, blower motor swaps, plus the occasional full system replacement or ductless addition. When we do replace equipment, we size it with a room-by-room load calculation rather than matching the old unit. Right-sized equipment holds even temperatures, keeps utility bills reasonable, and avoids the short-cycling that kills compressors early. Beyond repairs and replacements, we offer seasonal tune-ups that clean coils, confirm the refrigerant charge, test the safety switches, and measure static pressure, the most effective single step for longer equipment life.

Local businesses receive the same care. A hot dining room or a freezing office drives customers and staff away, so our commercial technicians focus on getting to the cause quickly and keep common parts on board for rooftop units, split systems, and ventilation equipment. Property managers, restaurant owners, and retailers can ask us to schedule work around their business hours whenever possible.

When Your System Fails in Green Bay

Call us with a problem and a real person picks up, not a phone tree. Most calls are scheduled within a day, and true emergencies, a dead air conditioner during a heat wave or a furnace that fails on a freezing night, jump to the top of the schedule. We keep the process simple so nobody is left waiting for a callback.

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 ignites and shuts off, a breaker that keeps tripping, an evaporator coil that has frozen, a condensate drain backed up into the furnace cabinet, or a thermostat that has quit. Nearly all of these trace back to a part we already carry: capacitors, contactors, igniters, flame sensors, universal control boards, and common fittings. You'll see the price up front, and that's the price you pay.

If your AC has iced over, the best 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, turn it off at the service switch and call (262) 401-5105. A few minutes of caution can head off a much larger repair.

Keeping Your Green Bay HVAC System Running Longer

Many mid-season breakdowns trace back to maintenance that never happened, and the habits that prevent them are simple. Swap your filter every one to three months, keep plants and shrubs at least two feet from the outdoor condenser, and hose off the condenser coil every spring. Then book a professional tune-up twice a year, one for cooling and one for heating, so our technicians can catch small problems while they're still cheap to fix.

How old is your system? That number says a lot about what comes next. Most well-maintained air conditioners make it to 12 to 15 years, furnaces 15 to 20, and heat pumps 10 to 15. If your system is past that point and also shows rising bills, rooms that never quite reach temperature, or frequent repairs, it's usually due for a planned replacement, which is almost always cheaper and easier on everyone than a rushed emergency install when the first heat wave hits.

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 miserable nights.

Typical Heating & Cooling Issues in Green Bay

Ask any homeowner around here what HVAC trouble looks like and you'll hear the same stories: 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: failing blower motors, low refrigerant charge, undersized returns, and years of skipped maintenance. Our technicians run into these problems every week and carry the parts to fix most of them in a single visit.

HVAC FAQ for Local Residents

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. Keeping up with both visits adds years to your equipment, helps prevent breakdowns in the middle of a heat wave or cold snap, and usually pays for itself in energy savings.
Most calls are scheduled the same day, and an emergency with no heat or no AC gets priority over routine work. When you call at (262) 401-5105, we'll give you a straight arrival window, and since the technician shows up with capacitors, contactors, igniters, and motors already on board, the job usually wraps up in one trip.
In many cases, yes. Ductless mini-splits work especially well in additions, converted garages, sunrooms, and older homes that were built without ducts. The process begins with sizing each zone to the actual room, followed by thoughtful placement of the indoor and outdoor units and a proper install of the line set, condensate drainage, and electrical connections. If central equipment would be the better fit for your home, we'll tell you.
Start with the simple checks: make sure the thermostat is set to cool with working batteries, look at the filter to see if it's clogged, and look for a tripped breaker on both the indoor and outdoor units. If everything looks normal and the outdoor unit is humming without starting, or you see ice on the copper lines, shut the system off before the compressor is damaged. Then call (262) 401-5105 and we'll dispatch a technician to your home right away.
It depends on two things: the system's age and what actually broke. Equipment younger than about 10 years is usually worth repairing. Once it's past 15 years, or if the compressor or heat exchanger goes, a new system is usually the better use of your money, particularly with the efficiency improvements of modern equipment. Our technicians will price both options honestly and let you choose.
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. If a system can't be saved, we manage the full 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 anything happens.
Every quote comes before any work starts, so you know the price up front. For a rough idea, typical repairs cost $150 to $650 depending on the part and system, and complete new systems run roughly $5,000 to $12,000 installed depending on size and efficiency. Your exact price comes from an on-site diagnostic at your home, and the price you approve is the price you pay, no surprises added later.
We work on nearly every brand installed in local homes, including Carrier, Trane, Lennox, Rheem, Goodman, and York, along with ductless equipment from Mitsubishi, Fujitsu, and LG. The universal parts on our trucks fit most units, and when a repair needs a brand-specific component, we can source it quickly.
