HVAC, Plumbing & Electric Services in Wauwatosa, WI

At ABC HVAC, Plumbing & Electric Services we understand that every system in your home works together.

When your heating fails on a January morning, your water heater starts leaking, or a circuit breaker keeps tripping, you need one reliable team that can handle it all. ABC Plumbing, Sewer, Heating, Cooling, and Electric is pleased to serve Wauwatosa homeowners, from the historic homes in Washington Highlands to newer properties in East Tosa. Our state-licensed technicians deliver same-day HVAC, plumbing, and electrical repairs with upfront pricing, so you'll see the total cost before we start any work.

Rapid HVAC, Plumbing, and Electrical Repair in Wauwatosa

We dispatch teams 24/7 for emergency calls across all three trades. Our service trucks carry diagnostic equipment and common replacement parts for brands installed throughout the Greater Milwaukee area, allowing us to complete most AC repairs that homes in Wauwatosa, WI, need on the first visit.

Air Conditioner and Heat Pump Repair

Wisconsin's humid summers strain cooling systems. We diagnose refrigerant leaks using EPA-certified leak-detection equipment, test capacitors and contactors with calibrated meters, and stock OEM parts for Carrier, Trane, Lennox, and Rheem systems commonly found in Wauwatosa homes built between the 1920s and the present day.

Furnace and Boiler Repair

Wauwatosa's older housing stock includes many cast-iron boilers and forced-air furnaces installed before 2000. We carry replacement igniters, flame sensors, and circulator pumps for these systems. Every no-heat call includes a carbon monoxide safety test using calibrated detectors. We'll install a new CO alarm if yours has expired or is missing.

Plumbing Emergencies and Water Heater Repair

Homes near Underwood Creek face higher water tables, which can stress sump pumps and basement plumbing. Before our team arrives, locate your main water shutoff (typically near the front foundation wall or basement meter). We'll repair or replace failed water heaters, clear drain blockages with professional augers, and pressure-test repairs before leaving.

Electrical Troubleshooting and Breaker Panel Issues

Many Wauwatosa homes still have 60-amp or 100-amp electrical panels insufficient for modern loads. Our emergency electrical services that Wauwatosa residents call for include tripped-breaker diagnosis, GFCI outlet replacement, and identification of aluminum wiring, common in homes built during the 1960s and 70s. We perform all electrical repair work in accordance with the current NEC code.

Installation and Replacement Services for Total Home Comfort

When equipment reaches the end of its 15-20 year lifespan, we provide written estimates that itemize equipment, labor, permits, and disposal fees. You'll receive manufacturer model numbers and efficiency ratings before approving any work.

Energy Efficient HVAC and Ductless Mini Splits

We perform Manual J load calculations to properly size replacement systems—oversized units cycle too frequently and undersized systems can't maintain comfort during temperature extremes. High-efficiency heat pumps with SEER2 ratings of 16+ and HSPF2 ratings of 8.5+ qualify for Focus on Energy rebates up to $2,200. We submit rebate paperwork on your behalf after installation.

Water Heaters, Sump Pumps, and Plumbing Replacements

Tank water heaters typically last 10-12 years; tankless units can reach 20 years with annual descaling. We install both types with thermal expansion tanks where required by code. Sump pump replacements include battery backup systems recommended for Wauwatosa's spring flooding patterns.

What Makes ABC the Trusted Choice for Wauwatosa Homeowners

ABC holds master licenses in plumbing (Wisconsin), HVAC (EPA 608 Universal certification), and electrical work.

Proven Guarantees on Parts, Labor, and Workmanship

New installations include a one-year labor warranty covering our workmanship. Manufacturer parts warranties range from 5-10 years, depending on equipment registered within 60 days of installation. We provide warranty claim assistance throughout the coverage period.

Licensed Technicians Across All Trades

Every technician carries state licensing, undergoes annual background checks, and completes 16 hours of continuing education yearly. Coordinating heating, plumbing, and electrical work through one company means unified code compliance and simplified permit coordination.
