Comprehensive Home Services
A comfortable home has multiple systems working together, including heating, cooling and plumbing. Instead of coordinating multiple contractors, keep Anton’s on speed dial for a full range of repairs, maintenance and installations.
Heating Services
Our technicians are experts in keeping your home warm during Illinois winters, servicing boilers, furnaces and geothermal systems. We can solve problems from unevenly heated homes to furnaces blowing cold air. If you’re concerned about energy efficiency, we can install a programmable thermostat to give you better control over your home’s indoor temperature.
Cooling Services
Did your AC motor stop working, or is your air conditioner leaking refrigerant? Our team can get your cooling system running again, whether you have a traditional central air conditioning system or a modern ductless one. Don’t forget to book an annual spring maintenance tune-up and ensure your AC is cleaned, inspected and ready for our humid Midwest summers.
Indoor Air Quality
The air you breathe affects your comfort and health. Anton’s provides advanced indoor air quality assessments and air purification solutions to remove pollen, mold, pet dander and dust. We also offer comprehensive air duct cleaning and sealing to reduce airborne particles. To manage moisture in your home, we can install and service dehumidifiers and humidifiers.
Plumbing Services
Our team handles routine repairs, maintenance and installation for sump pumps, tank and tankless water heaters, gas lines and kitchen and bathroom plumbing. Emergency services are available for burst pipes, water heater failure and other urgent issues.
Some problems may not need emergency repair but affect your comfort. Anton’s technicians can help if you notice low water pressure in parts of your home or a lack of hot water in the winter. If you’re tired of cleaning limescale stains, we can install a softener to reduce mineral content in hard water. We can also recommend a filtration system to reduce chlorine, heavy metals and other contaminants to enhance water taste and quality.
Drain Services
Slow, clogged drains can cause standing water, unpleasant smells and backups. Anton’s offers a full range of drain, rooter, sewer line and water line services. We clean, clear and repair drains to ensure water and waste flow normally.
Competitive Pricing
Maintaining your home shouldn’t be financially stressful. Anton’s provides clear, transparent pricing so you understand the work and cost before anything begins. You won’t pay more than you’re quoted, and we stand by our repairs.
