When your furnace stops working on a cold Illinois night or a pipe bursts in your basement, you need a local team with the training and tools to fix it right. ABC Plumbing, Sewer, Heating, Cooling, and Electric has served Union, IL homeowners for over 70 years with licensed technicians who provide upfront pricing, same-day service when possible, and warranties on both parts and labor.

What We Offer for Union Homeowners

ABC employs Illinois-licensed professionals for all three trades: HVAC, plumbing, and electrical. Each technician passes background checks and receives ongoing factory training to service the equipment in your home. We arrive in fully stocked trucks, allowing us to complete most repairs in a single visit. Our satisfaction guarantee covers workmanship, and we provide written estimates before starting any project, including routine maintenance.

Full HVAC, Plumbing, and Electrical Coverage

You won't need multiple contractors for different home systems. Our technicians diagnose heating, cooling, water, drainage, and electrical issues accurately because they work with these systems daily. We service equipment from major manufacturers, including Carrier, Lennox, Trane, Rheem, Bradford White, and others. All installations meet current Illinois building codes and manufacturer specifications.

Serving Union with Fast Response

Our dispatch system prioritizes emergency calls, and we maintain 24/7 availability for no-heat, no-cooling, sewage backup, and electrical safety issues. Because we've served McHenry County communities for decades, our team knows the common challenges in Union homes—from older electrical panels that need upgrading to frozen pipes during harsh winters.

Heating and Air Services

ABC installs, repairs, and maintains forced-air furnaces, boilers, heat pumps, and central air conditioning systems. We perform load calculations to size replacement equipment correctly and explain efficiency ratings (SEER, AFUE, HSPF) in plain language so you understand your options.

AC Repair and Installation

We repair refrigerant leaks, compressor failures, capacitor issues, and airflow problems in existing systems. For replacements, we review your home's insulation, ductwork condition, and square footage to recommend appropriately sized units. High-efficiency models qualify for utility rebates in some cases.

Furnace and Boiler Solutions

Our technicians test gas pressure, inspect heat exchangers for cracks, and verify carbon monoxide levels during every furnace service. We repair ignition systems, blower motors, and control boards. For boiler systems, we check pressure, temperature controls, and circulator pumps.

Indoor Air Quality Options

We install whole-home air purifiers, HEPA filtration, UV lights, humidifiers, and dehumidifiers integrated with your HVAC system. These additions help with allergies, dry air in winter, and excess humidity in summer.

Plumbing Solutions for Every Need

ABC handles water heater replacements, sewer line repairs, drain cleaning, repiping, fixture installations, and leak detection. We use video camera inspections to locate blockages and assess pipe condition before recommending repairs.

Drain and Sewer Line Services

Our motorized drain augers clear kitchen, bathroom, and main line clogs. For recurring issues, camera inspection identifies root intrusion, bellied pipes, or deteriorating cast iron. We perform trenchless repairs when conditions allow, reducing yard disruption.

Water Heaters and Fixture Upgrades

We install gas and electric tank water heaters (40–80 gallon capacity) and tankless units sized for your household's demand. Most water heater replacements are completed the same day. We also replace toilets, faucets, sinks, and garbage disposals.

Electrical Services to Keep You Safe

Our licensed electricians handle service panel upgrades, circuit additions, outlet installations, whole-house surge protection, and generator hookups. Every electrical project receives a permit when required and passes inspection.

Circuit Breakers and Panel Upgrades

Homes built before 1990 often need panel upgrades to support modern appliances. We replace outdated 100-amp panels with 200-amp service, add AFCI and GFCI protection, and label all circuits clearly.

Backup Generators and Wiring

We size and install automatic standby generators from 7kW to 22kW based on your household's power needs. Installation includes transfer switch setup, gas line connection (for natural gas units), and final inspection.

Flexible Financing and Specials

ABC works with approved lenders to offer payment plans for equipment replacements and major repairs. We also run seasonal promotions on maintenance agreements and equipment installations. Ask your technician about current offers during your service call.
