Green Bay HVAC Repair, Installation & Maintenance
Comfort in Green Bay shouldn't depend on the season. Eau Claire HVAC keeps local homes and businesses at the right temperature year-round with responsive, experienced heating and cooling service, from quick furnace repairs to properly sized new systems. Our technicians know the housing stock here, which means we've seen how these systems fail locally and we arrive prepared, with capacitors, contactors, igniters, and motors already on the truck. Call (534) 231-2225 and we'll get the fix started.

Heating and Air Conditioning Service Across Green Bay
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 doesn't matter whether the building is a starter home, a townhome, or a storefront. Our techs understand the local weather, the age and construction of local homes, and the code requirements that apply to new installations, which pays off in the quality of every repair.
Most homeowners we meet need one of three things: a repair, a replacement, or regular maintenance. Repairs are usually quick: a burned contactor, a dirty flame sensor, a refrigerant leak, or a seized blower motor. Replacements get a proper load calculation, not a guess based on the old unit's tonnage, which keeps temperatures even and stops the new equipment from short-cycling its way to an early failure. Maintenance visits include coil cleaning, a refrigerant charge check, safety control testing, and a static pressure reading, which does more than anything else to extend the life of your system.
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. Our commercial team understands 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 possible.
When Your System Fails in Green Bay
Heating and cooling failures rarely wait for a convenient day, which is why we offer fast, flexible scheduling for most situations. When you call, you'll speak with a real person who will get a technician headed to your property quickly. Our typical arrival window in the area is typically within a day for urgent calls, and a dead AC in a heat wave or a furnace out on a freezing night is exactly the kind of call we move to the front of the line.
The emergency calls we answer tend to follow a pattern. On the cooling side, it's an AC blowing warm air, an outdoor unit that hums without starting, or an evaporator coil iced over. On the heating side, it's a furnace that ignites and drops out. And any time of year, it's breakers that trip every cycle, clogged condensate drains overflowing into the furnace cabinet, and thermostats that have quit. Because our trucks are stocked with capacitors, contactors, igniters, flame sensors, universal control boards, and fittings, most of these get fixed on the first trip, at a price you approve before we start.
Two situations call for a quick step from you before our technician gets there. The first is an iced-over air conditioner: turn the system off at the thermostat and set the fan to "on" so the moving air thaws the coil, because running it frozen can overflow the drain pan and hurt the compressor. The second is a furnace that short-cycles or gives off a burning smell. Shut it down at the switch and give us a call. That small step can prevent a much larger repair.
How Green Bay Homeowners Can Extend HVAC Life
Many mid-season breakdowns start with maintenance that never happened, and the habits that prevent them are easy. Change your filter every one to three months, clear vegetation at least two feet from the outdoor condenser, and hose off the condenser coil every spring. Then book a professional tune-up each spring and fall, 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 tells you a lot. With regular service, most air conditioners make it to 12 to 15 years, furnaces 15 to 20, and heat pumps 10 to 15. If your system is beyond that range and is also showing rising bills, uneven temperatures, or repeated repairs, it's usually due for a planned replacement, which is almost always cheaper and easier on everyone than an emergency replacement when the first heat wave hits.
The earlier you report a comfort problem, the cheaper it usually is. A weak capacitor costs little to replace, yet that same capacitor, ignored for a season, can ruin the compressor and force a full system replacement. Save our number on your phone today so you can reach us fast the moment something sounds or feels wrong in your home. Early intervention saves time, money, and sleepless nights.
Typical Heating & Cooling Issues in Green Bay
Ask any homeowner around here what HVAC trouble looks like and the answers sound familiar: the AC that quit during the hottest week of the year, 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.
Trusted Local Service
Living and working here gives us firsthand knowledge of what local homes need to stay comfortable. From capacitors that quit in a heat wave to igniters that fail on the first cold night, our technicians know what to look for and how to fix it.

Choosing an HVAC company comes down to trust, and trust has to be earned. Eau Claire HVAC earns it by fixing what's fixable instead of replacing what isn't, by sizing replacements with real load calculations instead of guesswork, and by standing behind every repair after the truck pulls away. Same-day service is available for most calls, and every visit ends with the system tested and your questions answered.
