Most of the calls we answer come down to two things: a house that won't cool, or a house that won't heat. Here's how we handle both.
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. Every repair comes with an upfront quote and an honest opinion on repair versus replacement.
When the furnace clicks but never lights, lights and shuts off, or runs without warming the house, the cause is usually one component. We test the ignition, airflow, and safety controls to find it. 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.
HVAC trouble rarely announces itself politely. If you're seeing any of these problems, call us today for fast, professional help.
Warm air from the vents usually traces to a weak capacitor, a refrigerant leak, or a frozen coil, all fixable, and all diagnosable in one visit.
AC repairShort cycling wastes gas, stresses the heat exchanger, and never quite warms the house. We find the safety control tripping it and fix the cause.
Furnace repairThat slow decline in performance isn't age, it's neglect compounding. A proper clean-and-tune brings most systems back to spec in one visit.
Maintenance & tune-upsR-22 refrigerant, rust on the cabinet, a compressor on its second capacitor, these are signs the smart money is on replacement.
System replacementA 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 cleaningMini-splits deliver precise heating and cooling to a single zone, run whisper-quiet, and sip electricity compared to window units.
Mini-split installationAn HVAC system never fails at a convenient time. We schedule fast, show up on time, and arrive with the parts to finish the job.
The person at your door knows HVAC inside and out, from superheat readings to error codes, because we hire seasoned pros and keep them sharp on the methods that actually work.
If a $40 capacitor fixes it, that's what we'll tell you. We quote repair and replacement honestly, with real numbers, and let you choose, no scare tactics, no pressure.
We don't just swap the failed part. We check what killed it, airflow restriction, voltage, refrigerant charge, drainage, and correct that too, so the same failure doesn't repeat next season.
Year after year, Janesville HVAC has been the team local families call when the AC quits or the furnace goes cold. We've serviced systems in nearly every neighborhood around town, and that track record shapes how we approach each job, from the first diagnostic to the final test.
Our team doesn't just swap parts and leave. We check the airflow, the charge, and the electrical supply driving the failure common to properties around here. This local knowledge means faster diagnosis, fewer repeat visits, and systems that last.
One call connects you with a nearby technician who can size up the problem and get you a quote.
Our 4-step process is designed for accuracy, speed, and zero surprises on the invoice.
Call (920) 516-9404 and we'll get you a price quote, often within a day. A few quick questions, cooling or heating, what the system is doing, how old it is, and we'll book a time that works for you.
We inspect the whole system, not just the obvious symptom, and give you a straight answer: what failed, why, and what repair versus replacement really costs.
We complete the approved work on the spot whenever possible: quality parts, code-compliant connections, and no shortcuts hidden behind the air handler.
To keep your comfort reliable long-term, we can set up seasonal maintenance that cleans coils, checks the charge, and catches small issues before they strand you in the wrong season.

The first visit sets the tone. Here's how we respond when you call Janesville HVAC for emergency HVAC service.
When you call (920) 516-9404, you reach our local team directly. We listen to what's going on, note the details that matter, and get you on the books, often within hours, with quick guidance on what to do until we arrive.
Often within hours, our fully equipped technician is on-site with everything needed to handle the problem in your property.
The technician confirms exactly what failed and why, then fixes it on the spot, and if the system is beyond saving, walks you through right-sized replacement options with real numbers and a realistic timeline.
We don't disappear once the visit is done. We follow up to confirm everything is holding, and for systems in their later years we'll suggest the maintenance rhythm that keeps them reliable instead of surprising you.
"Our AC died on the hottest day of the year and a tech was out the same afternoon. He found a blown capacitor, swapped it from stock on the truck, and had cold air blowing before dinner. Fair price, no drama, and he checked the rest of the system while he was there."
"Another company quoted us a full system replacement. Janesville HVAC traced it to a failed blower motor and fixed it for a fraction of that quote. The tech said the rest of the system had years left in it. That kind of honesty is rare."
"From the estimate to the final walkthrough, the whole install was smooth and organized. The crew wore shoe covers, put down drop cloths, hauled off the old equipment, and the final bill matched the quote exactly. The new system is so quiet we barely notice it running. Highly recommend."
We treat your home the way we'd treat our own: thoroughly, honestly, and with an eye on the long term. Here's the standard you can count on from us every time.
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.
We size every replacement to your home's real heating and cooling load rather than defaulting to whatever's on the truck. Installations get done to code: sealed duct connections, correct line sets, proper condensate handling, clean electrical work. You get a system that performs for years, not just on day one.
A maintained system simply lasts longer, and we'd rather earn your trust than sell you a condenser early. Every maintenance visit is thorough and documented. For hard-working systems, a $40 capacitor caught early can save a $2,000 compressor. That's the Janesville HVAC way.
