Janesville homeowners, rental property owners, and commercial accounts across Rock County all deal with the same fundamental problem: heating and cooling systems that need to keep working through whatever the region throws at them. We handle the full range of HVAC repair, maintenance, and installation for Janesville and the surrounding communities. Whether the furnace stopped overnight, the AC is running but not cooling, or a system has reached the point where repair no longer makes sense, the call is where it starts. We are available every day from 8:00 AM to 8:30 PM.
Work in this area gets sized for the climate it actually runs in. That shapes every job we take on in Janesville, from a straightforward furnace tune-up to a full system replacement where the equipment has to be matched to a building that sees genuine winter cold and humid summer heat in the same twelve months.
Call (779) 259-3956 to get the work scheduled, or to ask what a visit covers before committing to anything.
When you call, the person who picks up knows the trade and can scope the job on the phone. You get the rate for the visit and what it covers before anything is booked. There is no obligation to schedule before you know what you are looking at.
For urgent situations, no heat and no cooling are handled as priority calls. A furnace that quits in the middle of a cold stretch is not a problem that can wait, and neither is a building where the cooling has gone down and tenants or customers are inside. We take short-notice work and answer calls every day from 8:00 AM to 8:30 PM. Ask what is available when you call and we will confirm it.
If the property has to stay occupied while the work is done, that gets factored in during the call. A business that cannot shut down for a day, a rental unit with a tenant in place, or a home where the heat cannot be off for more than a few hours: these are situations we work around, not obstacles to scheduling. The scope and the timing are settled before the technician arrives, not on the driveway.
The price for a service call is confirmed on the phone before anything is booked. What changes a quote from one job to the next is the nature of the work itself: what the fault turns out to be, how involved the repair is, whether the equipment has to come apart to reach the component that failed, and whether a repair is the right answer or whether replacement makes more sense given what the system is doing.
A diagnostic visit and a full system replacement are two different conversations with two different costs, and both of them start the same way: you call, we go through what the system is doing, and the rate for the visit is confirmed before we schedule. If the diagnostic turns up something that changes the scope, that conversation happens before any additional work is agreed.
Second opinions are welcome. If another contractor has already looked at the system and quoted a repair or a replacement, call and we will go through what a second diagnostic visit involves and what it costs. The goal is that you understand what the work covers before the technician arrives, not after.
A full system replacement is a larger job than a repair, and it is planned rather than same-day. The call covers the options, the equipment type, and how the new unit fits the existing setup, whether that is existing ductwork, a slab-mounted outdoor unit, or an air handler in a utility room. Sizing the equipment to the building matters more than most people expect. An undersized system runs constantly and still falls short. An oversized one short-cycles and wears out faster than it should.
When a furnace and AC are both at the end of their service life, replacing them together as a matched system is often the more practical path. The installation covers both units in a single visit rather than two separate jobs spread across seasons. For spaces without existing ductwork, a ductless mini-split handles both heating and cooling from a single outdoor unit without the need to run new duct runs through the building.
Before the installation visit, the equipment type and capacity are confirmed on the call. Compatibility with the existing electrical connections at the unit, the ductwork configuration, and the thermostat are all part of that conversation. Every installation is carried out to the manufacturer's specification, which is what determines how the system performs and how long it holds up. The scope, the equipment, and the price are all settled before anything is scheduled. The range of work covered is explained on the page covering our heating and cooling services.
Ductwork that leaks or was never properly sized for the building it serves shows up in ways that look like equipment problems. Rooms that never reach the set temperature, uneven heat or cooling from one end of the building to the other, energy bills that don't match the comfort level: these are the signs of a duct system that is working against the equipment rather than with it.
Duct repair and sealing does not require pulling the house apart. The process locates where the air loss is happening, seals the joints and connections that are letting conditioned air escape into unconditioned spaces, and confirms the result before the visit ends. Refrigerant, airflow and controls all checked before a verdict, which means ductwork gets examined as part of any diagnostic where the symptoms point toward an airflow problem.
For additions or rooms that were never connected to the main system, duct design and extension are handled as part of the installation conversation. The goal is a system that reaches every room it is supposed to reach, not one that was designed for a smaller floor plan and never updated.
The blower motor is what moves conditioned air through the ductwork and into the living space. When it starts to fail, the symptom is usually reduced airflow at the vents, a system that runs but doesn't seem to be doing much, or a motor that makes noise during operation. A service call covers the motor, the capacitor, and the belt or direct-drive assembly depending on the equipment type.
The compressor is the heart of the cooling side of any AC or heat pump system. A compressor that is drawing too much current, failing to build pressure, or cutting out on a high-pressure fault is not a problem that gets better on its own. Condenser coil issues, fan motor failures, and refrigerant circuit faults all fall within the same diagnostic visit, and the system gets checked through before any recommendation is made.
A burning smell at startup usually points to dust burning off after a long idle period, an overheating motor, or an electrical fault at the unit. A musty smell typically indicates biological growth somewhere in the system, most often on the evaporator coil or in the ductwork. Neither should be ignored. A service call identifies the source before anything else is done, because the fix depends entirely on what is causing it.
Boilers heat the living space through hot water circulated to radiators or radiant floor systems, and they are a different type of job from a forced-air furnace. Pressure faults, circulator pump failures, zone valve problems, and heat exchanger issues are all within scope. If the system is losing pressure, producing uneven heat across zones, or failing to fire, a diagnostic visit works through the boiler, the controls, and the distribution system to find the fault.
Joints that have separated, flex duct that has kinked or collapsed, and connections that were never properly sealed are the most common sources of duct air loss. A duct repair visit locates the problem areas, seals or replaces what needs attention, and confirms the result. Readings shared at the end of the visit give a clear picture of where the system stands before the technician leaves.
An addition that was built without extending the duct system properly is a room that will always be uncomfortable. Designing the duct extension involves calculating the load for the new space, sizing the supply and return runs correctly, and connecting them to the existing system in a way that does not rob airflow from the rest of the building. Where extending ductwork is not practical, a ductless mini-split handles the addition as a standalone zone without touching the existing system.
We serve Janesville and the surrounding communities throughout Rock County. That includes Milton, Hanover, Shopiere, Footville, and Fulton. If you are not sure whether your address falls within the service area, call and we will confirm it before anything is scheduled.
Residential calls and commercial accounts across the county are handled the same way: the job gets scoped on the call, the price is confirmed before the visit, and the work is done to the specification the equipment requires. We're ready to get your heating and cooling running again.
For most duct sealing work, the system needs to be off while the technician accesses and seals the connections. The duration depends on how much ductwork is being addressed. We will go through the expected scope on the call before the visit is booked so you know what to expect.
Sometimes. Whether a system can be kept going depends on what the diagnostic finds. If the fault is repairable and the repair cost makes sense against the remaining useful life, keeping the system running for another season is a reasonable choice. That conversation happens after the diagnostic, based on what the equipment actually needs.
The diagnostic visit is how we look at the system, and the price for that visit is confirmed before it is scheduled. You do not commit to a repair or a replacement before the visit happens. The scope and the cost of the diagnostic are settled on the call so you know what you are agreeing to before the technician arrives.
Homes in this part of Wisconsin typically run gas furnaces paired with central air conditioning, though heat pumps and ductless mini-splits are becoming more common, particularly in additions and renovations. We work on all of them, including boilers and hydronic systems. If you are not sure whether your equipment is within scope, describe it on the call and we will confirm it.
