Frequently asked
I’ve been providing reliable residential HVAC service in the Chicago area since 2005, which means I’ve been working with central split-system AC and furnace combos for over 21 years. That’s a lot of experience installing, repairing, and maintaining these systems in homes across Illinois.
Yes, I provide a dedicated 24/7 emergency line for urgent no-heat/no-cool situations. While my normal business hours are Monday through Friday from 7am to 5pm, I understand that when your system fails in the middle of winter or sweltering summer heat, you need help right away. You can call the emergency line anytime for immediate service.
I focus exclusively on residential central split-system air conditioning units and furnaces. My work includes servicing condenser pad service dollies, furnace filter and coil service carts, duct static-pressure gauges, capacitor and contactor test meters — all tools that help me properly diagnose and fix issues in these specific systems.
I recommend having your central split-system AC and furnace serviced at least twice a year—once before the cooling season begins, and once before winter arrives. Regular maintenance ensures your system runs efficiently, helps prevent costly breakdowns, and extends the life of your equipment.
