When something stops working, the first question is always whether the equipment can be fixed or whether it has to go. That answer depends on what the diagnostic turns up, how far along the equipment is, and whether the cost of the repair makes sense against what a replacement would run. We work through that on the call and again on site, so you have the information before anything is scheduled.
We handle the full range of heating and cooling work for homes and rental properties in Lisbon.
Whether a furnace has stopped producing heat, an AC is running but not doing its job, or a system is simply past the point where repair makes sense, call (414) 451-9289 and we will talk through what the situation calls for.
We cover Lisbon and the surrounding area, open every day from 6:30 AM to 11:00 PM.
A furnace that won't fire, a system that runs but blows cold air, a heat exchanger that has seen too many seasons: these are the calls that come in most often during a Waukesha County winter. The diagnostic covers ignition components, heat exchanger condition, burner performance, and airflow through the system. Each of those tells a different part of the story. When repair is the right call, we complete it. When the equipment is at the end of its useful life, we walk through replacement options before anything is scheduled.
Modern cold-climate heat pumps are rated to operate efficiently well below freezing, which makes them a practical fit for this region rather than a seasonal compromise. They handle both heating and cooling from a single system, and installation involves a load calculation for the home, equipment selection matched to what the local temperature range actually demands, and integration with existing ductwork or a ductless configuration where the home does not have ducts. State and utility incentive programs in Wisconsin have made the upgrade more accessible, and the interest from homeowners here reflects that.
A room that the existing ductwork never properly reached, a garage that needs to be conditioned, a finished basement that runs warmer or colder than the rest of the house: these are the situations where a ductless mini-split makes sense. Installation does not require tearing into existing duct runs. The indoor head mounts on the wall or ceiling, refrigerant lines run through a small penetration to the outdoor unit, and the system handles heating and cooling independently of whatever the central equipment is doing.
An AC that will not start at all is a different problem from one that starts but underperforms. The diagnostic looks at the capacitor, the contactor, the thermostat signal, and the refrigerant charge before any parts are quoted. A refrigerant leak, for example, shows up as a system that runs but cannot reach temperature, while a failed capacitor stops the compressor or the fan before the system gets going at all. Getting the diagnosis right is what the visit is for.
A fall furnace tune-up and a spring AC check catch wear before it becomes a failure. In a region where heating carries the load for the better part of the year, skipping the fall check means the first cold night is the first real test of the season. A maintenance visit covers cleaning, inspection of key components, and confirmation that the thermostat is communicating correctly with the system before the technician leaves.
When the equipment is old enough that repair costs are climbing toward what a replacement would run, or when the same components keep failing season after season, replacement is the practical answer. We size the new system to the home, not to what was there before, because an undersized or oversized unit creates its own problems. Central air installation, furnace replacement, and heat pump installation all fall here.
Forced-air heating pulls moisture out of the indoor air, and in a long regional heating season that adds up. Dry air is uncomfortable, and it puts stress on wood floors, trim, and furniture. A whole-home humidifier integrates with the furnace and duct system, conditioning air throughout the house rather than treating a single room. Installation connects to the supply plenum and return air, and a humidistat keeps the output calibrated to what the home actually needs.
The rate is confirmed on the call before anything is scheduled. Ask what the visit covers, what the diagnostic fee is, and what the job is likely to involve, and you get a straight answer. There are no commitments before you have that information.
What moves a quote is the situation on site. The fault that turns up during the diagnostic, what has to be reached to fix it, and whether the repair is straightforward or whether the equipment needs to come out entirely all affect the final scope. If the technician finds something during the visit that changes what the job involves, the updated scope and price are confirmed with you before any additional work goes ahead.
We'll confirm the repair with you before it goes ahead.
A high-efficiency rating on a piece of equipment is a number measured under controlled conditions. What a property actually sees depends on factors the rating does not account for: duct leakage, insulation, the age of the home's envelope, and how well the equipment was sized for the space it is conditioning. An oversized furnace short-cycles and wears components faster than one matched to the load. An undersized AC runs constantly and still cannot keep up on the hottest days.
Energy-efficiency upgrades make the most difference when the whole system is considered, not just the unit. Duct sealing, thermostat and smart-control installation, and correct sizing at replacement all contribute to what the equipment actually delivers once it is running in the home. A system that is tuned and properly matched to the space will outperform a higher-rated unit dropped into a leaky duct system without adjustment.
System tuned. Airflow balanced. Home comfortable.
Filtration and humidity are separate problems with separate solutions, and both affect how a home actually feels to live in.
On the filtration side, a higher-efficiency filter or a whole-house air purifier that integrates with the existing system addresses dust, allergens, and particulates throughout the house rather than in one room. The right choice depends on the system's airflow capacity, because a filter that restricts airflow too much creates its own performance problems.
On the humidity side, the heating season in this region is long, and forced-air heat runs for months. A whole-home humidifier set to the right level keeps the indoor environment comfortable and protects the materials in the home. The thermostat or humidistat controls the output, so the system responds to conditions rather than running at a fixed rate.
If a previous repair did not solve the problem, or if you want a second opinion before committing to a replacement, call us. We take over work started by someone else regularly, and the approach is the same as any other diagnostic: we assess what the system is doing, check what was done before, and give you a clear picture of where things stand.
We also handle situations where a property has had ongoing issues that were addressed piecemeal rather than properly diagnosed. Sometimes the same component keeps failing because the underlying cause was never found. A thorough diagnostic on the system as a whole is often what resolves a pattern of recurring problems.
One call gets the whole thing moving.
Short-notice work is available depending on what the schedule allows when you call. For a property with no heat in the middle of winter, that call moves to the front of the conversation. Emergency calls are taken every day from 6:30 AM to 11:00 PM, and availability is confirmed when you reach us.
For rental properties and tenants who cannot be without heat or cooling, we work around the situation on the call. If a tenant needs to be present for access, that gets coordinated before the visit is scheduled. For commercial properties that have to stay open, the scope and timing are discussed up front so the visit does not disrupt operations more than necessary.
We're one phone call from getting your comfort right.
We cover Lisbon and the surrounding communities in Waukesha County. Sussex, Merton, Lannon, Pewaukee, and Richfield are all within our area, and if you are not sure whether your address is covered, call and ask. Most of the time the answer is yes.
Coverage across this area means the same work, the same pricing process, and the same approach to the diagnostic whether the call comes from a Lisbon home or a property in any of the neighboring towns. Built for homeowners. Ready for property managers. Ready for your system. If you would rather read than call, the list of HVAC services we handle has the detail.
Yes. A complete diagnostic or maintenance visit covers both the indoor unit and the outdoor unit, because the two work as a system and a problem in one often shows up as a symptom in the other. Checking only one side of the system can lead to a misdiagnosis.
In some cases, yes. Whether a temporary measure is practical depends on the component that has failed and the type of system. We discuss what is possible on the call and confirm any temporary arrangement before the visit is closed.
Yes. Older forced-air systems with standing pilot furnaces, non-programmable thermostats, or original ductwork from decades back are common in homes this size and age, and we diagnose and repair them the same way we would any other system. If the equipment is at the point where parts are hard to source or the repair cost no longer makes sense, we will say so and walk through what replacement would involve.
Yes. We service ductless and mini-split systems regardless of who installed them. The make and model are helpful to have when you call so we can prepare for the visit, but the diagnostic starts from what the system is doing.
When you call, we scope the situation on the call with you, confirm the rate, and coordinate access with whoever needs to be present at the property. If the tenant is the point of contact for the visit, that gets established before anything is scheduled. Property managers and landlords across Waukesha County use us for both reactive repair calls and planned maintenance, and the process is the same either way.
If the system is running but behaving abnormally, such as making unusual noises, producing no output, or cycling erratically, switching it off until the technician arrives prevents further wear on components that may already be stressed. If it is running normally but underperforming, leaving it on is generally fine. Describe the situation when you call and we will advise.
Whatever the equipment is doing, or not doing, we will come out and look at it.
