When the air conditioning quits or the furnace won't light, you need a technician who finds the real problem and fixes it the same day.
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. Pricing is upfront, and we'll tell you honestly whether a repair is worth it on an older unit.
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. Every visit includes a safety check of the burners and venting, and you'll know the price before we start.
Most failures start small and give you clues first. Below are the warning signs local homeowners run into most, and any one of them is reason enough to call us for a closer look.
Low refrigerant, a failed compressor start, or a dirty condenser can all masquerade as the same symptom. Real diagnosis beats parts-swapping every time.
AC repairIf the blower runs but the air never warms, or the unit clicks without lighting, the failure is diagnosable in minutes with the right tools.
Furnace repairEnergy bills creeping up while comfort drops means the system is working harder than it should, dirty coils, clogged filters, or failing motors are the usual suspects.
Maintenance & tune-upsA system past 12 to 15 years that needs a repair every season is telling you something. We'll give you the honest math on repair versus replacement.
System replacementYour ducts move the same air thousands of times a day. Years of dust, dander, and construction debris ride along until they're cleaned out.
Air duct cleaningWe size and mount mini-splits cleanly, proper line sets, condensate handling, and a tidy exterior finish, so they work as good as they look.
Mini-split installationWhen the heat is out in January, hours matter. Our local technicians roll out same-day with stocked trucks, ready to repair on the spot.
We don't cut corners. Our team is experienced, background-checked, and fluent in every major brand, from a 20-year-old gas furnace to the newest inverter-driven heat pump.
Plenty of companies sell a new system the moment yours hiccups. We diagnose first, explain what actually failed, and only recommend replacement when the math genuinely favors it.
Installations get the full treatment, real load calculation, correct line sets, sealed and balanced ductwork connections, and a complete commissioning test before we leave.
For over a decade, West Allis HVAC has been the go-to team for HVAC service in this part of WI. Our hometown technicians know the specific conditions that affect systems in this area, from the age of local housing stock and its ductwork quirks to coastal air that corrodes condenser coils.
Our team doesn't just swap parts and leave. We know the failure patterns, duct issues, and code details common to properties around here. This local knowledge means we catch problems other companies miss and keep your home comfortable.

A house with no AC in a heat wave gets dangerous, not just uncomfortable. Here's what our team does from your first call to restore your comfort fast.
Our team answers your call promptly, gathers key details, cooling or heating, running or dead, any error codes on the thermostat, and books your visit, often same-day. We'll walk you through switching the system off if it's iced over or short-cycling in the meantime.
Often within hours, our fully equipped technician is on-site with everything needed to diagnose and begin the repair in your home or business.
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 offer spring and fall tune-up plans, so you never have to think about it, to clean coils and test components before they cost you a compressor. Staying ahead of the problem lasts years longer and runs cheaper every month.
"Years of dust, pet hair, and who knows what else came out of our ducts. After the cleaning, rooms that never got air finally do, and my wife's morning allergies have all but disappeared. They showed us before-and-after photos of everything they pulled out."
"The furnace quit at 11 pm with the temperature dropping fast and a newborn in the house. They answered right away and talked me through checking the thermostat and breaker, then had a technician out first thing. Heat was back before noon. Absolute pros."
"We put a ductless mini-split in the bonus room over the garage that no vent had ever reached. They measured and calculated instead of eyeballing it, and the install was clean and quick. That room is finally usable year-round."
We do more than patch the symptom. We give you lasting comfort. Every visit is backed by experienced technicians, quality parts, and a focus on fixing the cause.
Real experience is a requirement, not a bonus. It means every technician reads refrigerant and electrical faults correctly, works clean and safe, and explains the work in plain language at a level most companies don't reach.
Effective doesn't have to mean oversold. We size systems honestly and install them to code with quality fittings and clean workmanship, so you get reliable comfort with minimal disruption to your household.
Our team believes in keeping systems alive with inexpensive seasonal care. If you want years more from your current equipment, our spring and fall maintenance visits handle the checks that actually extend equipment life. No surprises, no hidden fees. This focus on longevity is why so many homeowners recommend us.
