All services · 24 in 4 groups
Every heating and cooling service we offer in Northbrook
24 services in four groups, from a furnace that won't light to a restaurant's make-up air unit.
Heating: furnaces, boilers and heat pumps
A furnace that won't light, a boiler losing pressure, a unit that short-cycles. Diagnosis comes first, and replacement only if the unit is genuinely done.
Furnace and heater repair
Ignition, flame sensors, inducer motors and limit switches, found and fixed on the first visit where the part is on the van.
Boiler service
Hot-water and steam boilers in vintage two-flats and converted lofts: pressure, circulators, zone valves, venting.
Furnace installation and replacement
Sized to the unit, not the brochure. In a high-rise, routed around building rules on venting and access.
Heater maintenance
An autumn tune-up before the first cold snap: burners, heat exchanger check, filters, safeties.
Heat pumps
Repair and installation, including cold-climate units for townhomes moving off gas.
Hybrid heating systems
A heat pump paired with a gas furnace, switching over on the coldest days.
HVAC maintenance plans
Scheduled heating and cooling visits for buildings that want them on the calendar.

Why Chicago homeowners keep calling the same family
★★★★★Susan NusbaumGoogle review, 2025I called City & Suburban Heating to have my furnaces cleaned. They told me that Rob was going out of town for a week. I asked he could come before he left, and he came two days after my call. I had forgotten to buy a furnace filter for one of the furnaces, but luckily he had it in his truck. He is very reliable and does a great job.
Read moreTwo-furnace cleaning ★★★★★Lena HallgrimsdottirGoogle review, 2026Highly recommend this service. Responsive, reliable, and reasonable pricing. Twice in the past few years, Rob has fixed our aging furnace but this frigid Friday night it kicked the bucket for good. Saturday morning the guys were at our house putting up a new one. Excellent customer service, punctuality, and clear explanations. C&S Heating look for solutions to fix vs selling you unnecessary spare parts.
Read moreFurnace replacement ★★★★★Jaeyoon LeeGoogle review, 2025Very quick response and was clear on the issue and solution! Rob came out to our place to assess the issue on our furnace and fixed it within a same day! He was transparent on the status of the furnace and provided the solution of the issue im having right away. Definitely found a local business who I can rely on that will come back for sure!
Read moreSame-day furnace repair ★★★★★Todd FeitlGoogle review, 2026Great experience. I called them for my second opinion. Fast, friendly and efficient service. I was told my unit is near end of life but the prices I was quoted are great and they will definitely be hearing from me again when it's time. Use this company. Update: had my ac, furnace, and water heater replaced yesterday. Not sure I could be happier.

The process · 6 steps
What happens when you call
From the first call to a warm apartment, in six steps
01/ 06
01 You call, Rob listens
Tell us the make of the furnace or condenser and what it's doing. A good description often narrows it down on the phone.
02 Pick a time
We're available 24/7. If your building has rules on access, like elevator or work hours, tell us and we book around them.
03 On-site diagnosis
The technician finds the actual fault: ignition, pressure, refrigerant, airflow or controls.
04 Honest price, repair first
You hear the price before any work. If the unit has years left, we say so and repair it.
05 We fix it
Repairs done on the spot where the part is on the van. Installs are scheduled and quoted separately.
06 Good to go
The system is tested through a full cycle before we leave, and you know what to watch for.

Scope & price · 6 factors
The same repair costs differently in a 1960s house, a townhome and an office
We don't publish a price book, and we're not going to invent one here. What we can show you is what moves the number.
How we price
- The person who diagnoses is the person who quotes.
- You hear the price before any work starts.
- No flat-rate price book, no commissioned adviser.
- Where the unit has years left, the quote is for a repair.
"What does a new furnace cost?"
$6,807Chicago median
Median reported value of 81 central-furnace replacement permits in Chicago over 24 months. That's the whole project's construction value, not a quote. Yours depends on the factors below.
Factor · why it changes the work
- 01
Two systems, two floors
Larger Northbrook houses can run a furnace and AC for each floor, so a repair starts with finding which system has failed.
- 02
Heat pumps in newer homes
Newer houses and townhomes may run heat pumps, which heat and cool. The repair depends on which half has failed.
- 03
Townhome associations
In townhome and condo associations, the rules on outdoor units and access shape when and how the work is done.
- 04
Basement or attic units
Furnaces sit in basements, but some newer houses put a second unit in the attic, which changes the access.
- 05
Stores and offices
Shops on Lake Cook Rd and offices on Sanders Rd run rooftop units, so roof access and business hours set the work.
- 06
Repair or replace
The biggest swing of all. Where the unit has years left, we say so.

Where we fit, honestly
City & Suburban is a family-owned Chicago company. In Northbrook we're the right call for condo, house, loft and restaurant heating and cooling: repairs, boilers, furnaces, central air and make-up air. Tower central plants and new-build mechanical systems are for the big mechanical contractors, and we'll tell you so.

The permit record, honestly · Northbrook
Why there's no permit chart for Northbrook
Northbrook is outside Chicago, so the City's permit file stops at its border. Here is what we can honestly say about permits there.
Northbrook HVAC permits
The Village of Northbrook issues its own building permits and doesn't publish them as open data, so there's no count to chart for Northbrook.
The honest context
0Permits on record for City & Suburban. We said we'd be honest.
1,539Firms that pull HVAC permits citywide, across 4,888 permits in 24 months.
Outside Chicago, each suburb sets its own permit rules, mostly for installs and replacements. Either way, a permit file measures construction, not service. So when a company waves a permit count at you, ask how much of their work is repair.
FAQs · 5 questions
Northbrook HVAC, answered
Didn't find your question?
Call (773) 238-3838Since 1952Family owned, licensed, NATE-certified
01Is the furnace in my 1960s house worth repairing, or does it need replacing?
Often it's worth repairing. We diagnose first, and where the furnace has years left, we say so. Replacement is quoted only when the repair stops making sense.
02Do you come out to Northbrook from Chicago?
Yes. Northbrook is on our service area list, about 16 miles north-west of the shop at 1225 N Cleaver St, and Rob runs the calls from there.
03Can you service both systems in a two-zone house?
Yes. Furnace and air conditioning repair and maintenance are on our list of services. Tell us which floor isn't heating or cooling, and we start there.
04Does HVAC work in Northbrook need a permit?
It depends on the job. The Village of Northbrook takes mechanical permit applications for heating and cooling work, mostly installs and replacements. Ask whoever quotes an install who pulls the permit.
05What are your hours?
Our working hours are 24/7. Call (773) 238-3838.
Your next step
No heat, no cooling, or just a question?
Have the make of your furnace or condenser to hand, and tell us what it's doing. If the house has two systems, tell us which floor has the problem.
