What areas does CCC Mechanical serve?

CCC Mechanical serves Chicago and the northwest suburbs from 6097 N Northwest Hwy, Chicago, IL 60631, including Arlington Heights, Buffalo Grove, Elmwood Park, Melrose Park, Niles, Northbrook, Park Ridge, Norridge, Harwood Heights, Oak Park, Elmhurst, Lombard, Hinsdale, Oak Brook, Burr Ridge, Downers Grove and Westmont.

Do you give a price before starting the repair?

Yes. We diagnose the problem first, then give a firm price before any work begins, so you approve the cost up front. If a repair is not worth the money on an aging system we say so and price the replacement alongside it.

How often should I change my furnace filter?

Change a standard one-inch filter every one to three months, and a thicker four- or five-inch media filter every six to twelve months. A clogged filter is the most common cause of service calls we see: restricted airflow makes a furnace overheat and trip its high-limit switch, or freezes the AC evaporator coil.

What does the $95 A/C Clean and Check include?

A full pre-season AC tune-up: condenser coil cleaning, refrigerant charge verification, capacitor and contactor testing, condensate drain clearing, filter check and temperature split confirmation, with findings given in writing.

What is included free with a new HVAC installation?

Every complete furnace or AC installation includes a Honeywell T5 WiFi smart thermostat and an Aprilaire whole-home humidifier at no extra cost, professionally installed and configured. Applies to new installations only.

How long should a furnace last in Chicago?

A well-maintained gas furnace in the Chicago area typically lasts 15 to 20 years. Chicago's roughly six-month heating season puts far more run hours on a furnace than a milder climate, so skipped maintenance shortens that lifespan considerably.

Is CCC Mechanical licensed and insured?

Yes. CCC Mechanical LLC holds an Illinois HVAC license and carries active liability insurance, both verified by Google as part of the Google Guaranteed program, which also requires background checks on the business and its technicians.

HVAC Services in Chicago & the Northwest Suburbs

Furnace & Heating Repair

No heat, short cycling, a blower that won't start, an igniter that won't light, we diagnose gas furnaces, boilers, and heat pumps and quote the fix before we touch it. Chicago heating season runs six months; we treat no-heat calls as emergencies

Air Conditioning Repair & Installation

Warm air, weak airflow, leaking refrigerant, a condenser that won't start we fix it, and if the system is past saving we size and install the right replacement instead of the biggest one.

Furnace & AC Replacement

Right-sized, properly installed, correctly commissioned. We run a real load calculation instead of matching whatever was there before, so your new system actually hits its efficiency rating.

Indoor
Air Quality

Chicago homes trap dust, allergens, and humidity. We test your indoor air and fix what the test finds filtration, humidifiers, dehumidifiers, UV purification, ventilation, and duct sealing.

Preventative Maintenance

Two visits a year heating before winter, cooling before summer. Catches the small failures before they become the 2 a.m. no-heat call, and keeps your manufacturer warranty valid.

Commercial
HVAC

Rooftop units, light commercial installs, and scheduled maintenance for offices, retail, and small industrial buildings across Chicagoland. Service agreements built around your hours, not ours.

We clean the condenser coil, verify refrigerant charge, test the capacitor and contactor, clear the condensate drain, check the filter, and confirm your temperature split is where it should be — then tell you exactly what we found, in writing. Finding a weak capacitor in May costs $95. Finding it during the first 95° week costs you a compressor and a week of waiting.

Aprilaire Whole-Home Humidifier

Free With Install

Chicago winter air can drop indoor humidity below 20% — dry sinuses, static shocks, cracked trim, and separating hardwood floors. An Aprilaire whole-home humidifier ties into your ductwork and holds the whole house at a comfortable 35–45%. Free with every new HVAC installation, professionally installed and set up. Properly humidified air also feels warmer, so most homeowners run the thermostat lower.

01
We install Carrier, Bryant, York, Ducane, Honeywell and Aprilaire equipment, and we service every major furnace and air conditioning brand regardless of who installed it. Bryant is our most-installed residential line because it offers reliable equipment at a fair price. Carrier covers our premium efficiency work, including 96% AFUE two-stage furnaces and the WeatherMaker commercial rooftop line. York is chosen for durability and excellent Chicago-area parts availability, and Ducane offers value-focused equipment built on Lennox engineering. For controls we install Honeywell thermostats, and Aprilaire supplies our whole-home humidifiers, dehumidifiers and high-efficiency media filtration.
02
Yes. We diagnose the problem first, then give you a firm price for the repair before any work begins, so you approve the cost up front. We do not start work and hand you a surprise invoice afterward, and we do not pad the job with parts you do not need. If the honest answer is that a repair is not worth the money on an aging system, we will tell you that and price the replacement alongside it so you can compare the two. Call 630-827-9024 to book a diagnosis.
03
CCC Mechanical offers six core services: furnace and heating repair, air conditioning repair and installation, full furnace and AC replacement, indoor air quality work, preventative maintenance, and commercial HVAC. On the heating side we diagnose gas furnaces, boilers and heat pumps. On the cooling side we handle refrigerant leaks, weak airflow and condenser failures, and install replacements when a system is past saving. Indoor air quality covers testing plus filtration, humidifiers, dehumidifiers, UV purification, ventilation and duct sealing. Commercial work covers rooftop units, light commercial installs and scheduled maintenance for offices, retail and small industrial buildings.
04
Yes. A house with no heat in a Chicago winter is not a routine service request, and we prioritize no-heat calls accordingly. Beyond the discomfort, an unheated home risks frozen and burst pipes, which turns an HVAC repair into a plumbing and water damage claim. While you wait, keep interior doors open to help heat circulate, open the cabinet doors under sinks on exterior walls, and let a faucet drip if temperatures are well below freezing. Call 630-827-9024 and tell us it is a no-heat call so we can route it correctly.
