HVAC Repair, Installation, And Maintenance For Wisconsin Weather

Wisconsin's temperature swings from sub-zero January nights to humid 90-degree summers, putting serious stress on heating and cooling equipment. Our HVAC technicians service all residential systems: natural gas and propane furnaces, hot water and steam boilers, central air conditioners, ductless mini-splits, and dual-fuel heat pumps.

Many West Allis homes were built between 1920 and 1960 with original cast-iron radiators or gravity furnaces. We specialize in retrofitting these older homes with modern high-efficiency equipment while preserving existing ductwork when possible. For furnaces and boilers over 15 years old, we'll test efficiency, check for carbon monoxide leaks, and provide honest repair-versus-replace guidance based on your equipment's condition and your budget.

Our seasonal tune-ups catch problems before they cause breakdowns. Each maintenance visit includes a safety inspection, burner cleaning, heat exchanger examination, blower motor testing, and thermostat calibration. We check refrigerant levels on AC systems and test electrical connections on all equipment.

Plumbing Services That Protect Your Home's Value

West Allis homes built before 1960 often have galvanized steel supply pipes that corrode from the inside, reducing water pressure and causing rusty water. We perform whole-home repiping with PEX or copper when corrosion is widespread, or targeted repairs for isolated problems.

Our plumbing services cover water heater repair and replacement, main line and fixture drain cleaning, sump pump installation with battery backup, sewer camera inspections, and emergency leak repairs. We use video inspection to diagnose sewer line problems without excavation, and recommend trenchless pipe lining when tree roots or bellied sections cause recurring backups.

Keep Basements Dry Year-Round

Spring snowmelt and summer storms overwhelm older sump pumps. We install 1/2 HP or 3/4 HP pumps based on your basement size and water table depth, with battery backup systems that activate during power outages. Warning signs of pump failure include constant cycling, loud grinding noises, and visible rust on the motor housing.

Safe, Code-Compliant Electrical Upgrades And Repairs

Many West Allis homes still operate on 60-amp or 100-amp service panels installed in the 1950s and 1960s. These outdated panels can't safely handle modern loads from central air conditioning, electric vehicle chargers, and multiple kitchen appliances running simultaneously. Our licensed electricians upgrade service panels to 200-amp capacity, install new circuit breakers, and handle all permit applications and city inspections.

We troubleshoot recurring problems like flickering lights (often caused by loose neutral connections), tripped breakers (indicating overloaded circuits), and warm outlets (a sign of poor wire connections or aluminum wiring). For homes with aluminum wiring installed in the 1960s and 1970s, we install COPALUM connectors at all switches and outlets to prevent fire hazards.

Every technician holds current state licenses in their trade, carries liability insurance, and completes background checks before joining our team. We provide written quotes before starting work, with line-item pricing that shows parts, labor, and any applicable fees.
