Last February, when the polar vortex hit Portage Park, we got 47 calls in one night. Families woke up to cold houses and broken furnaces. One lady on Laramie Ave had her pipes freeze because her boiler quit at 2am. We sent our guy Mike out there in the middle of the blizzard. He got her heat back on before the sun came up.
That's what we do. Bernie's has been fixing HVAC systems in Chicago since 1992. When your furnace breaks or your AC dies on the hottest day of summer, we show up. No runaround, no sales pitch. Just honest work.
Based Near Portage Park, Built for Chicago HVAC Work
Our shop is at 3704 N Cicero Ave, right by Portage Park and minutes from Jefferson Park, Irving Park, and Belmont Cragin. That Northwest Side base matters: we know the bungalows, two-flats, tight basements, old duct runs, steam boilers, and parking headaches that make Chicago HVAC work different.
When we head outside the neighborhood, we use the same routes Chicago homeowners use every day. A Naperville service call usually means working west from Cicero through the expressways toward I-88, while closer calls run through Milwaukee, Lawrence, Irving Park, or Cicero depending on traffic. That route context matters because it reflects real service coverage from our local base, not a generic list of cities copied onto a page.
Your Local Chicago HVAC Contractor for Heating, Cooling, and Everything In Between
Most folks don't think about their furnace until it stops working. Then they're scrambling to find someone who'll pick up the phone at 9pm on a Saturday. We get it. That's why Bernie built this company around repair-first HVAC service - Chicago needed contractors who actually answer when you call and don't try to sell you stuff you don't need.
Heating Contractor
Chicago winters ain't no joke. When it's 10 below and your furnace starts making weird noises, you need someone who knows what they're doing. We work on all kinds of heating systems - gas furnaces, boilers, heat pumps, you name it. Been doing it since before most of these big companies even existed.
The thing about furnace repair is, sometimes it really does just need a lower-cost part. That's not how we roll. If it can be fixed, we'll fix it. If it's really dead, we'll show you why before we talk about replacing it.
We install a lot of high-efficiency furnaces around Portage Park and Irving Park. The new ones are way better than what people had 20 years ago. They use less gas, heat better, and they're quieter. Most installs take us one day, maybe two if we're redoing ductwork. And we clean up after ourselves - your basement won't look like a construction site when we leave.
Air Conditioning Contractor
Summer in Chicago can be brutal. When your AC quits working and it's 95 degrees with 80% humidity, you need it fixed fast. We do emergency AC repair all over the city. Most times we can get someone out same day, sometimes within a couple hours if you're local.
A lot of AC problems are simple - low refrigerant, dirty coils, bad capacitor. We carry parts on the truck so we can fix it right there. No waiting around for days while we order stuff. And if your system is old and on its last legs, we'll be straight with you.new one would save you money on your electric bill.
We've been installing central air conditioning systems in Chicago for decades. Two-flats, bungalows, bigger houses - we've done them all. The key is sizing it right and making sure your ductwork can handle it. Too many contractors just slap in whatever and call it good. That's how you end up with hot spots and high bills.
Furnace Repair Service
When your furnace breaks in the middle of winter, you don't want a sales guy showing up trying to sell you a new system. You want a mechanic who can figure out what's wrong and get your heat back on. That's what we send - actual technicians who've been fixing furnaces for years.
Common stuff we see: bad igniters, cracked heat exchangers, blower motor issues, thermostat problems. Sometimes it's just a clogged filter that nobody changed for two years. We'll diagnose it, tell you what it costs to fix, and let you decide. No pressure, no BS. If we say you need it, you actually need it.
We do 24/7 emergency furnace repair because we know heating emergencies don't wait for business hours. Call us at 3am, we'll answer. And if you're a regular customer, no overtime charges. You're already stressed about your furnace - we're not gonna gouge you on top of that.
Air Duct Cleaning Service
Your ducts get dirty. Dust, pet hair, construction debris if you did any remodeling - it all ends up in there. Then your furnace or AC blows it around your house every time it runs. Not great for allergies or air quality.
We use a big truck-mounted vacuum system for duct cleaning. It's way more powerful than those little portable units some guys use. We go through your whole system - supply ducts, return ducts, the furnace itself. Takes a few hours but you'll notice the difference. Less dust on your furniture, better airflow, and your HVAC system doesn't have to work as hard.
A lot of places in Belmont Cragin and Albany Park have old ductwork with leaks and gaps. While we're in there cleaning, we'll check for that stuff too. Sealing up leaky ducts can cut your heating and cooling bills by 20-30%. That's real money every month.
Commercial HVAC
We do commercial work too - restaurants, retail shops, small office buildings. Commercial systems are different from residential. They run harder, longer hours, and when they break it costs you money every minute they're down.
Restaurants are tricky. You've got kitchen exhaust, makeup air, dining room AC that needs to keep running even when it's packed. We work with a bunch of places around the Northwest Side. The key is preventive maintenance - catching problems before they turn into emergencies during your busy season.
For retail and offices, we can set up maintenance agreements so we come out regularly and keep everything running smooth. It's cheaper than emergency repairs and your system lasts longer. Plus we're familiar with your setup so if something does break, we already know your building and can fix it faster.
Why Chicago HVAC is Different
Chicago weather beats the hell out of HVAC systems. We go from 10 below in January to 95 and humid in July. That's a huge swing. Your furnace and AC work harder here than they would in most other places. That's why regular maintenance matters - you're asking a lot from these systems.
The other thing about Chicago is the housing stock. Lots of old buildings, lots of bungalows and two-flats with weird layouts and basements that weren't really designed for modern HVAC. We've been working in these houses for 30 years. We know how to run ductwork in tight spaces and deal with old radiator systems that someone converted to forced air back in the 70s.
And parking. We know the neighborhoods - where we can park the van, what streets to avoid during rush hour, which alleys are too narrow for our truck. Sounds small but it means we show up on time and don't waste your time circling the block looking for a spot.
