West Allis HVAC Company handles the full range of residential and commercial heating and cooling work in West Allis and across Milwaukee County.

Call (414) 451-9289 for a quote. We are open every day from 6:30 AM to 11:00 PM.
Some homes need a full system replacement. Others just need a tune-up.
The scope of what we handle covers everything between those two ends. AC repair and service when the system stops cooling. Heating repair when the furnace goes quiet. Heat pump service for systems that handle both seasons. Full HVAC system installation and replacement when the equipment has run its course. Ductwork repair and sealing when airflow problems are pointing that way. Thermostat and smart-control installation when the controls are not keeping up with the schedule. Indoor air quality work when what is in the air matters as much as the temperature. Seasonal maintenance before the heating or cooling season gets underway.
We handle residential calls and commercial work across the area, and every job gets code-compliant HVAC work on every job, whether it is a single-unit repair or a full building installation.
Give us a call and we will take care of it.
When you call about an HVAC repair or installation, the price is confirmed before anything gets scheduled. Ask what the visit covers, what the rate is for the service call, and what the job is likely to involve, and you get a straight answer. There are no commitments before you have the information you need.
Getting the diagnosis right is what the visit is for. The technician who comes out assesses the system, works through the symptoms, and confirms what the job covers before any repair goes ahead. For an AC that is not cooling, that means checking refrigerant charge, the condenser, and the evaporator coil before parts are quoted. For a heating system, it means checking heat exchanger condition, ignition components, and airflow before a recommendation is made. The thermostat is confirmed as communicating before sign-off, so the system is not just running when the technician leaves, it is responding correctly to the controls.
We'll confirm the repair with you before it goes ahead.
Dealing with a furnace that won't keep up or an AC that can't cool?
A no-heat call in January in Milwaukee County is not something that waits until Monday. A furnace blowing cold air, a furnace short cycling, a heat pump that has stopped producing heat, a boiler that has gone offline, an AC that is running but not cooling the house down: these are the calls that need to move quickly.
Call (414) 451-9289 and the person who picks up knows the trade, can scope the situation on the phone, and gets the right help moving.
We take emergency calls every day from 6:30 AM to 11:00 PM. One number. One call. One HVAC tech at your door.
Call (414) 451-9289 when the system goes down.
Your home deserves heating and cooling that runs right, and in this part of Wisconsin, that means being ready for both extremes. West Allis winters bring sustained sub-freezing temperatures and heavy snow, and a heating system that is not reliable is a real problem. Summers are shorter but humid, and a cooling system that cannot handle the load makes the season uncomfortable fast. The services below reflect what West Allis homes and buildings actually need most.
A gas forced-air furnace is the standard heating setup in most West Allis homes, and when it stops working in the middle of winter, the call is urgent. Furnace repair work covers ignition system diagnosis, heat exchanger inspection, blower motor performance, and airflow through the supply and return. When a furnace is at the end of its service life, replacement involves sizing the new unit to the home, confirming the flue and venting arrangement, and making sure the system is set up to run efficiently from the start. Ductwork is checked when the symptoms point that way, because a duct problem that goes unaddressed will show up again in the next heating season.
Modern variable-speed cold-climate heat pumps are rated to operate in temperatures well below freezing, some down to roughly -15 degrees Fahrenheit, which makes them a practical option for Milwaukee County homes that previously depended entirely on gas heat. They move heat rather than generate it, which changes the energy profile of the home, and state and utility incentive programs in Wisconsin have made the upgrade more accessible. Installation involves equipment sizing for the home's load, refrigerant line set routing, indoor air handler placement, and connection to existing ductwork or a ductless configuration depending on what the home requires.
Forced-air heating and long Wisconsin winters are a combination that pulls moisture out of the indoor air. Low humidity causes dry skin, static, and discomfort, and it can affect wood floors, furniture, and trim over time. A whole-home humidifier integrates directly with the furnace and duct system, adding moisture to the air as it circulates through the home. Installation involves selecting a bypass or fan-powered unit based on the system configuration, connecting to the supply plenum and return air, and setting the humidistat to maintain a consistent indoor humidity level through the heating season.
We know schedules shift, so we keep your booking flexible, and the range of work we handle means one call covers most of what a home or building needs on the heating and cooling side.
Beyond the featured services above, here is what we handle:
We're one phone call from getting your comfort right.
West Allis is the center of our service area, and we work across Milwaukee County and the communities around it. Homeowners and property managers in Wauwatosa, Greenfield, and Hales Corners call us for the same heating and cooling work we do throughout the area. We also serve Greendale, New Berlin, and Brookfield to the west, and Cudahy and the south side of Milwaukee when the job is there.
If you are not sure whether your address falls within the area, call and ask. Most of the time the answer is yes.
One call gets the whole thing moving.
We serve West Allis as our primary city and cover the surrounding Milwaukee County area, including Wauwatosa, West Milwaukee, Greenfield, Greendale, Hales Corners, New Berlin, Brookfield, and Milwaukee.
If you are not sure whether your address falls within the area, call (414) 451-9289 and we will confirm it quickly. Most of the time the answer is yes.
It helps to know the make and model of your equipment before you call, along with a description of what the system is doing or not doing. If the system has error codes showing on the thermostat or control board, note those down. The more detail you can give on the call, the more accurately we can scope the visit and give you a rate before anything is scheduled.
Short-notice work is available depending on the schedule, and emergency calls are taken when you reach us. When you call, we confirm what is available and get the visit scheduled from there. We do not promise a specific arrival window on this page, because availability depends on what is already on the schedule when you call.
The rate and scope are confirmed on the call before anything is scheduled. If the technician finds something during the diagnostic that changes what the job involves, we confirm the updated scope and price with you before any additional work goes ahead. Nothing moves forward without your sign-off on what has been agreed.
Someone should be available to provide access to the equipment, whether that is the indoor unit, the furnace, or the outdoor condenser. If you cannot be home, arrangements can be discussed on the call. Property managers coordinating access for a tenant unit can work through the same process.
Clearing a path to the furnace or air handler and removing anything stored directly around the outdoor condenser helps the visit go faster. The technician who comes out needs to reach all sides of the equipment to complete the diagnostic or the service. If access is limited, let us know on the call and we can advise on what to clear.
Yes. We handle heating and cooling calls for rental properties and multi-unit buildings across Milwaukee County, including both reactive repair calls and planned maintenance.
Property managers can call (414) 451-9289 to discuss how the work is scoped and priced, and we confirm the rate before any visit is scheduled.
Fast turnaround on tenant no-heat and no-cool calls is part of what we do.
If the diagnostic uncovers a problem that is larger than what the symptoms suggested on the call, the scope may expand. Parts that need to be ordered, additional ductwork issues found during the visit, or a system that turns out to need replacement rather than repair can all affect the final cost. We confirm any change in scope with you before the work proceeds, so there is no ambiguity about what you are agreeing to.
When repair costs are climbing toward a significant fraction of what a replacement system would cost, or when the same components are failing repeatedly, replacement is worth discussing. Age matters too: a furnace or AC that is well past its expected service life and losing efficiency is costing more to run each season. Call us and describe what has been happening, and we will walk through the options so you can decide what makes sense.
An inspection is the right starting point when the system is still running but showing signs of trouble, such as uneven temperatures, unusual sounds, or higher energy bills. If the inspection finds that the core components are worn beyond practical repair, replacement becomes the conversation. We scope the situation on the call and confirm what the visit will cover before anyone comes out.
What is covered after the initial visit depends on what was agreed on the call. Ask about follow-up coverage when you book, and we will give you a straight answer on what the rate includes. We confirm the repair with you before it goes ahead, and any follow-up need is handled the same way: scoped and priced before the visit is scheduled.

West Allis HVAC Company handles the full range of heating and cooling work for homes and commercial properties across West Allis and Milwaukee County. The table below lays out what each service covers, who it fits best, and a practical note to help you decide what to schedule. Call us with any questions and we will scope the job on the call before anything is booked.
| Service | What It Covers | Common Needs | Helpful Details |
|---|---|---|---|
| Seasonal Maintenance & Tune-Ups |
| Homeowners who want to catch small issues before a no-heat or no-cool call | Fall is the right time to tune the furnace before the heating season. Spring is the right time to check the AC before the first hot stretch arrives. |
| Heating Repair & Service |
| Any home or rental property that has lost heat or is heating unevenly | Forced-air gas heat is the dominant system type in West Allis, and most common failure points are diagnosable in a single visit. |
| Emergency HVAC Service |
| Any situation where the home has lost heating or cooling and cannot wait | We take emergency calls every day from 6:30 AM to 11:00 PM. Short-notice work is available. Call us and we will scope the situation on the call. |
| Thermostat Installation & Smart Controls |
| Homeowners upgrading controls or troubleshooting a system that behaves erratically | A thermostat that is not reading the system correctly can cause problems that look like equipment failures. We check it as part of every diagnostic. |
| AC Repair & Service |
| Homeowners with an AC that won't cool or keeps cycling off | A diagnostic visit checks the system before parts are quoted, so you know what you are dealing with before any work begins. |
| HVAC System Installation & ReplacementMost Popular |
| Homeowners replacing aging equipment or upgrading to a higher-efficiency system | Equipment is sized for the home before installation begins. The thermostat is confirmed as communicating before sign-off so the whole system is verified. |
| Furnace Repair & Replacement |
| West Allis homeowners facing a furnace that won't heat or a system nearing the end of its useful life | When repair cost climbs relative to what a new furnace would cost, replacement is worth discussing. We walk through the options before anything is scheduled. |
| Indoor Air Quality & Air Filtration |
| Households dealing with dust, allergens, dry air, or air circulation concerns | System-level filtration treats air throughout the house rather than one room. Whole-home humidifiers tie into the ductwork and run on a humidistat calibrated to what the home needs. |
| Heat Pump Repair & Service |
| Homes with a heat pump that has stopped heating or cooling | Heat pump diagnostics differ from a standard furnace or AC call. The reversing valve and defrost behavior both factor into what the system is doing. |
| Boiler & Hydronic Heating Service |
| Homes with hot-water baseboard or radiant floor heating | Boiler calls require a different diagnostic approach than forced-air systems. Zone valve behavior and circulator pump condition both affect whether heat reaches every room. |
| Ductwork Repair & Sealing |
| Homes with uneven temperatures, dusty registers, or rising energy bills | Ductwork is checked when the symptoms point that way. A refrigerant charge or coil cleaning only solves part of the problem if conditioned air is leaking into unconditioned space. |
| Cold-Climate Heat Pump Installation |
| Homeowners looking to add high-efficiency heating and cooling in a single system | Modern cold-climate heat pumps are rated to operate efficiently at temperatures as low as roughly -15 degrees Fahrenheit, making them a practical fit for Wisconsin winters. |
