Doing HVAC work right matters, and we'll help you get it right, whether you're a homeowner dealing with a broken furnace in February or a property manager keeping a commercial building comfortable year-round. Tempco Heating & Air Conditioning has been the go-to heating and cooling contractor in West Allis since 1969, and in 57 years of working across Milwaukee County, we've handled just about every HVAC situation there is. From AC repair and seasonal tune-ups to full system installation and emergency no-heat calls, we cover the full range of residential and commercial heating and cooling work. We pick up the phone and take care of it. You'll have clear communication from the first call to the final test, and you'll always know what's happening with your system before we do anything. Dependable service. Honest rates. Local HVAC know-how.
Not every HVAC company works the same way, and the difference usually shows up in the details. We started in 1969 as a small local operation, and we've spent more than five decades learning the homes, the buildings, and the seasonal demands of this part of Wisconsin. Milwaukee County winters are hard on heating systems, and the summers, while shorter, can get warm and humid enough to make a working air conditioner feel like a necessity. We understand that rhythm because we've been working in it for generations.
Our work is performed by qualified HVAC technicians who know residential and commercial systems inside and out. We serve single-family homeowners, landlords managing rental properties, small business owners, and property managers who need a contractor they can count on to show up and get it right. No-pressure estimates, priced up front, so there are no surprises when the job is done. We'll handle the system so you don't have to.
Good HVAC work isn't complicated, it's just done right, and that starts with having the experience to handle whatever a customer needs. We're a full-service heating and cooling contractor, which means we work on the whole system, not just one piece of it.
Here's what we handle:
This is everyday work for everyday customers. We're not a specialty shop that handles one type of system or one season. Whether you need a quick repair, a full replacement, or a seasonal checkup before the cold arrives, we're the call to make. We make the repair and leave the home tidy.
Dealing with an AC that can't cool? Wisconsin summers don't last forever, but when the heat and humidity settle in, a failed air conditioner makes the house genuinely uncomfortable. We handle the full range of cooling work, from diagnosing an AC that's blowing warm air to replacing an aging central air system that's past its useful life.
Common calls we get include AC units that won't turn on, systems that run but can't keep up with the heat, uneven temperatures from room to room, and refrigerant leak concerns. We also handle seasonal AC tune-ups before summer arrives, so the system is ready when you need it. If you're replacing an older unit, we'll help you choose the right size and configuration for your home or building. Prompt response, even for last-minute comfort calls, is how we operate. Call for a quote and we'll get someone out to take a look. Call today and we'll get the temperature back where it belongs.
The quality of an HVAC repair or installation comes down to the people doing the work. Our technicians have hands-on experience across a wide range of heating and cooling systems, from older cast-iron boilers in historic West Allis homes to modern variable-speed heat pumps and high-efficiency furnaces. They know how to read a system, diagnose the real problem, and fix it correctly the first time.
We don't send out whoever is available. The technicians who show up at your door understand the equipment they're working on and take the job seriously. That experience matters whether the call is a minor repair on a warm afternoon or an emergency no-heat situation at midnight in January.
Choosing the right HVAC fix is easier than it sounds when you're working with someone who knows the equipment. A furnace that stops working in the middle of a Milwaukee County cold snap isn't just uncomfortable, it can become a safety concern quickly. We respond to no-heat calls and get the system diagnosed and running as fast as possible.
We handle furnace repairs, furnace inspections, annual tune-ups, and full furnace replacements when the old system has reached the end of its life. If you're replacing an aging furnace, it's also a good time to look at whether a heat pump makes sense for your home. Cold-climate heat pumps have improved significantly, and for the right property, they can handle Wisconsin winters efficiently alongside or instead of a gas furnace. We'll walk you through the options and help you make the right call for your situation and budget.
Many of the homes in West Allis were built before central ductwork was standard, and adding full duct systems to an older home isn't always practical or cost-effective. Mini-split and ductless systems are a clean solution for those situations. They deliver targeted heating and cooling to specific rooms or zones without requiring ductwork throughout the house.
We install ductless systems for room additions, finished basements, garages, and older homes where a traditional central system doesn't fit the layout. Qualified HVAC technicians handle the sizing and installation, which matters because an undersized or poorly placed unit won't perform the way it should. If you've been living with a room that's always too hot in summer or too cold in winter, a mini-split is often the most practical fix.
Leaking or damaged ductwork is one of the most common causes of uneven temperatures and higher energy bills. If some rooms in your home are never quite comfortable, the ducts are worth inspecting. We handle duct sealing, duct repair, and full ductwork replacement where the existing system is too far gone to fix. Getting the duct system right makes the whole HVAC system perform better.
A thermostat that isn't working correctly can make a perfectly good HVAC system feel unreliable. We install programmable and smart thermostats that give you real control over your home's temperature schedule. It's a straightforward upgrade that pays off in comfort and, over time, in lower energy use.
Milwaukee County winters mean the house stays closed up for months at a time, and indoor air quality can suffer as a result. We install whole-home air filtration systems, air purifiers, and whole-home humidifiers that address the dry indoor air that comes with running a heating system through a long Wisconsin winter. If the air in your home feels stale, dry, or irritating, there are practical solutions that work with your existing HVAC system.
A February no-heat call in West Allis is a real emergency, not an inconvenience. When the furnace goes out overnight or the AC fails during a summer heat stretch, waiting days for a technician isn't an option. We offer emergency HVAC service because we know the local climate and what it means when a system goes down at the wrong time.
We respond to no-heat and no-cool calls, systems that won't turn on, and HVAC equipment that shuts down without warning. Same-day service options are available, and we'll get a qualified technician to your home or building as quickly as we can. Simple booking. Clear pricing. Reliable, lasting comfort.
Property managers and business owners have different needs than a typical homeowner, and we understand that. A commercial HVAC problem affects employees, tenants, customers, and operations, so the response has to be fast and the repair has to hold. With 57 years of experience working across Milwaukee County, we've built the kind of track record that commercial clients can rely on.
We handle commercial AC repair, commercial heating repair, rooftop unit service, and ongoing HVAC maintenance for offices, retail spaces, multi-unit properties, and small industrial buildings. Scheduling regular service for a commercial system keeps it running efficiently and helps catch problems before they turn into expensive failures. We work with property managers who need a dependable contractor on call and business owners who need the system handled without disruption to their day.
We're based in West Allis and serve customers throughout Milwaukee County and the communities that surround it. Our service area includes Milwaukee, Wauwatosa, Greenfield, Brookfield, New Berlin, Hales Corners, Greendale, and West Milwaukee, along with the neighborhoods and properties in between. If you're in the area and need heating or cooling work done, we're a local call away.
We have been locally owned and operating in West Allis since 1969, which puts us at more than 57 years of continuous service in this community. That kind of history means we know the neighborhoods, the housing stock, and the seasonal demands of this part of Wisconsin. When you call, you reach someone with real roots here.
Yes. We are locally owned and based in West Allis. When you call, you reach someone who is personally accountable for the work and who knows this area firsthand. We pick up the phone and take care of it.
We have been working in West Allis and the surrounding Milwaukee County communities for over five decades, so yes, we know the neighborhoods and the kinds of homes in them. Older West Allis homes often have specific ductwork configurations, older equipment, and heating systems that require experience to diagnose correctly. That local familiarity makes a real difference on the job.
Milwaukee County winters are long and demanding on heating systems, and the forced-air furnaces that heat most homes in the area also dry out indoor air significantly over a long heating season. We have spent decades working on the equipment that handles those conditions, and we understand what tends to fail, when it tends to fail, and how to address it correctly.
If something is not right after we leave, call us and we will come back to look at it. We stand behind the work we do, and we do not consider a job finished until the customer is satisfied. Prompt response, even for last-minute comfort calls, applies to callbacks as much as it does to new service calls.
Our technicians arrive with the tools and common parts needed to handle most repairs on the first visit. We take care of the work area and leave the home tidy when the job is done. That is a basic standard we hold ourselves to on every call.
We respect your time and work to arrive within the scheduled window. If something changes and we are running behind, we communicate that rather than leaving you waiting without an update. Reliable, consistent service is something we take seriously.
No. We provide no-pressure estimates, priced up front, so you know what the work costs before we start. Parts and labor are explained clearly, and if anything changes during the job, we discuss it with you before proceeding. There are no surprises on the final invoice.
When you're ready to get your heating or cooling system looked at, Tempco Heating & Air Conditioning is the call to make. We work with homeowners, landlords, and commercial clients across the West Allis area, and we handle everything from a quick repair to a full system replacement. No-pressure estimates, priced up front, so you know what you're getting into before the work begins.
Call (414) 451-9289 to request an estimate, schedule a service call, or ask about a repair. We're available for emergencies around the clock, and we offer same-day scheduling options when your situation can't wait. Whether it's a furnace that stopped working or an AC that needs attention before summer, we're ready to help.
From a quick AC repair to a full furnace replacement, we handle the complete range of heating and cooling work for West Allis homes, rental properties, and commercial spaces.

How do I know if I should repair my furnace or replace it?
We look at the age of the equipment, the cost of the repair, and how reliably it has been running. A furnace that is fifteen or more years old and facing a costly repair is often a better candidate for replacement than another round of fixes. We walk through the numbers with you honestly so you can make a decision that makes sense for your budget and your home.
What are the signs that my AC or furnace needs attention now?
Weak airflow from the vents, warm air coming out of a running air conditioner, the system turning on and off in short cycles, or unusual noises like banging, rattling, or squealing are all signals that something is wrong. Any of those symptoms means the system needs a diagnosis before the problem gets more serious. Call us and we will get a technician scheduled.
How often should I schedule a maintenance tune-up?
Once a year for each system is the standard recommendation. A furnace tune-up in the fall before heating season and an AC tune-up in the spring before cooling season keeps both systems running at their best and catches small issues before they turn into expensive repairs.
Same-Day and Emergency Availability
When your heat goes out in a Wisconsin winter or your AC quits during a summer heat stretch, we respond the same day. We take calls every day of the week and prioritize urgent no-heat and no-cool situations.
What does a seasonal tune-up actually include?
We inspect and clean key components, check refrigerant levels, test the controls and safety switches, and flag anything that looks like it could cause a problem down the road. The goal is to confirm the system is ready for the season ahead and to give you an honest picture of its condition.
Why is one room in my home always hotter or colder than the rest?
Uneven temperatures are usually caused by duct leaks, an undersized or poorly balanced duct system, or a zoning issue. In some cases, a dirty filter or a struggling blower motor is restricting airflow to certain parts of the house. We diagnose the root cause rather than guessing, and we explain what we find before recommending a fix.
Can I try to fix an HVAC problem myself before calling a technician?
Checking your thermostat settings, replacing a dirty filter, and making sure the system has power are all reasonable first steps. Beyond that, HVAC equipment involves refrigerant, electrical components, and heat exchangers that are best left to a qualified technician. Attempting a repair without the right training and tools can make the problem worse or create a safety issue.
Transparent Upfront Pricing
We give you a clear estimate before any work begins, and we communicate openly if anything changes during the job. You will never be surprised by the final number.
Do I need to be home when the technician comes out?
Someone should be present to let the technician in and to hear the findings and recommendations at the end of the visit. If that is not possible, let us know when you schedule and we will work out the best arrangement for your situation.
How does pricing work, and will I know the cost before work starts?
We provide no-pressure estimates, priced up front, so you know what the work costs before we begin. If something unexpected comes up during the job, we talk with you about it before moving forward. There are no surprises when the job is complete.
Experienced With Older and Newer Systems
We have been doing this work in the West Allis area since 1969, which means we have seen a wide range of equipment, from older systems that have been running for decades to the latest cold-climate heat pumps and smart controls.
What causes a system to short-cycle, and is it a serious problem?
Short-cycling, where the system turns on and off repeatedly without completing a full heating or cooling cycle, is usually a sign of an underlying issue. Common causes include a dirty filter restricting airflow, a refrigerant problem, an oversized system, or a failing component like a pressure switch or thermostat. It puts extra wear on the equipment, so it is worth getting diagnosed sooner rather than later.
What is involved in upgrading to a smart thermostat?
We install the new thermostat, connect it to your existing system wiring, configure the settings, and confirm it is communicating correctly with your heating and cooling equipment. If you want zoning controls or have a more complex system, we handle that as well. The whole process is usually straightforward and completed in a single visit.
How can I improve the air quality and humidity in my home?
A whole-home air filtration or purification system installed on your existing HVAC equipment reduces dust, allergens, and airborne particles throughout the house. A whole-home humidifier addresses the dry-air problem that comes with running forced-air heat through a long Wisconsin winter. We can walk you through both options and what installation involves.
