Keeping Homes Cool in Summer and Warm in Winter

When the air conditioning quits or the furnace won't light, you need a technician who finds the real problem and fixes it the same day.

AC Repair in Oshkosh

Most air conditioner breakdowns trace back to one failed part: a weak capacitor, a burned contactor, a seized fan motor, or a slow refrigerant leak. We diagnose it with gauges and meters, not guesswork. You get a clear price before any work starts, and if the system is old enough that replacement makes more sense, we'll show you both numbers.

  • AC running but blowing warm air
  • Outdoor unit humming but not starting
  • Ice on the refrigerant lines or indoor coil
  • Water leaking near the indoor unit
See how we handle AC repairs

Furnace Repair in Oshkosh

A furnace that won't light on a cold night can't wait until morning. Most no-heat calls come down to a dirty flame sensor, a failed igniter, or a blower motor, and our trucks carry the common parts to fix them on the spot. We also check for the problems that matter for safety, like a cracked heat exchanger, and give you an upfront price before any work begins.

  • Furnace clicks but never lights
  • Short cycling on and off
  • Cold air from the vents in heating mode
  • Loud banging, squealing, or grinding at startup

HVAC Problems We Solve

When Homeowners Should Call for Help

Most failures start small and give you clues first. Below are the warning signs local homeowners run into most, and any one of them is reason enough to call us for a closer look.

AC Blowing Warm Air

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 repair

Furnace Won't Stay On

If the blower runs but the air never warms, or the unit clicks without lighting, the failure is diagnosable in minutes with the right tools.

Furnace repair

Rising Bills, Weak Airflow

Energy bills creeping up while comfort drops means the system is working harder than it should, dirty coils, clogged filters, or failing motors are the usual suspects.

Maintenance & tune-ups

Old System, Repeat Repairs

We size replacements with a real load calculation, not a guess, so the new system delivers even temperatures and lower bills from day one.

System replacement

Dusty Air & Musty Smells

A musty smell at startup often means moisture in the ducts or a dirty evaporator coil, worth addressing before it becomes a bigger air-quality problem.

Air duct cleaning

Rooms That Never Get Comfortable

A garage office, a converted attic, or that one bedroom the ducts never reached, a ductless mini-split solves it without tearing open walls.

What Clients Say

Our Customers Speak for Themselves

★★★★★
Rated 4.8/5 · 150 reviews

"Our restaurant's rooftop unit failed on a Friday with a full weekend of reservations booked. Their team had us cooling again before the dinner rush. They clearly understood what downtime costs a Oshkosh business, and they came back the next week to fully service the second unit. Customer for life."

Marcus T.
Oshkosh, WI

"We put a ductless mini-split in the bonus room over the garage that was always freezing in winter and roasting in summer. They measured and calculated instead of eyeballing it, and the install was clean and quick. That room is finally usable year-round."

OA
Omar A.
Oshkosh, WI

"When our old furnace was on its last legs, they walked us through converting to a heat pump instead of just quoting a like-for-like swap. The first winter's bills were noticeably lower, and we got cooling out of the same equipment. Zero regrets on this one."

Our Commitment

Why Neighbors Keep Calling Us Back

Good HVAC service comes down to doing the small things right. These are the commitments that earn Oshkosh HVAC repeat customers and referrals year after year.

Experienced Technicians

We don't send a rookie with a gauge set and a hope. Each technician brings genuine field experience in diagnosis, safe gas and electrical work, and clean installation, the kind of depth that turns a service call into a lasting fix.

Right-Sized, Code-Compliant Work

Doing it right is built into how we install. We handle the refrigerant, gas, electrical, and airflow details precisely, pull permits where local code requires them, and commission the full system before we call it done, and we tell you what we did and why.

Maintenance That Pays for Itself

A maintained system simply lasts longer, and we'd rather earn your trust than sell you a condenser early. Every maintenance visit is built around your system's age and condition. For hard-working systems, a spring coil cleaning is the difference between year 10 and year 15. Period.

Quick Answers

Your Questions, Answered

Most air conditioner repairs in Oshkosh run between $150 and $650, depending on the part. Common fixes like capacitors, contactors, and fan motors sit at the lower end, while compressor and refrigerant work costs more. If the system is beyond economical repair, full replacement typically ranges from $5,000 to $12,000 installed depending on size and efficiency. We diagnose first and give you a clear, upfront quote before any work begins.
A good rule of thumb: if the system is under 10 years old and the fix is a component, capacitor, motor, igniter, sensor, repair usually makes sense. If the compressor or heat exchanger has failed, the unit is past 12 to 15 years old, or repairs are stacking up season after season, replacement is the smarter investment. Our technicians walk you through both numbers honestly so you can decide with real information.
We offer same-day and emergency HVAC service throughout the Oshkosh area. Our trucks carry the most common parts, capacitors, contactors, igniters, flame sensors, and universal motors, so the majority of repairs are completed in a single visit. Even full system replacements are usually scheduled within days, not weeks.
For many Oshkosh homes, yes. Modern heat pumps heat and cool from a single system, run far more efficiently than electric resistance heat, and current models perform well even in cold weather. They cost more upfront than a basic AC swap, which is why we run the numbers on your actual usage and utility rates before recommending one.
Yes. Our technicians work on all major residential and commercial brands and system types, central air conditioners, gas and electric furnaces, heat pumps, packaged units, and ductless mini-splits. We carry universal parts on the truck and can source brand-specific components quickly when needed.

Don't Wait for the Weather to Win.

The longer a struggling system limps along, the more it costs you. One call gets you same-day service and a clear quote from a team that knows Oshkosh.
