HVAC emergency in Chicago? Call Bernie's Heating & A/C Service now! Same-day service available for all heating and cooling emergencies.
Last January this lady in Albany Park called at 3 AM. No heat, house at 52 degrees, 8 below outside. Furnace igniter was shot—could of been caught during a fall tune-up. Instead she paid emergency rates and froze half the night.
Annual furnace tune-ups catch problems before Chicago winter hits. We clean burners, test ignition, check for heat exchanger cracks (carbon monoxide saftey), and make sure your furnaces ready for polar vortex. This isnt a sales call—most furnaces just need cleaning and maybe a small part. $89 tune-up or included in our $179/year maintenance plan.
Were not gonna sugarcoat it—most furnaces dont explode if you skip maintenance. However, heres what does happen based on what we see in homes across Lincoln Square, Ravenswood, and Edgewater every winter:
Your furnace dies at 2 AM when its 5 below outside. Igniters crack, flame sensors get dirty, blower wheels seize up. Tune-ups catch these before there emergencys. We see this pattern every January in older Chicago bungalows.
Dust buildup on burners and blower wheels reduces efficiency 15-25%. That means your furnace burns more gas to produce the same heat. A $89 tune-up pays for itself in gas savings over the winter, especially in drafty old Chicago homes.
Cracked heat exchangers leak CO into your home. We check this during every tune-up. Found 3 cracked heat exchangers last fall in furnaces 15+ years old around Portage Park. This is serious—we dont mess around with CO safety.
No vague promises. Heres exactly what we do during the $89 tune-up. This is the same checklist weve used since 2008 for homes all over the north side:
Test gas pressure, flame pattern, and combustion efficiency. If somethings off, we catch it now instead of when your furnace dies mid-January.
Check for cracks that could leak carbon monoxide into your home. This is the big saftey check—we use cameras to see inside if needed.
Clean burners and flame sensor. Dirty sensors cause nuisance lockouts where your furnace randomly shuts off—super annoying at night.
Test igniter and check for cracks. Igniters fail alot in furnaces 7+ years old. We catch em when there starting to crack, not after they fail.
Pull and clean blower wheel if dirty. Dust buildup reduces airflow 15-25% and makes your furnace work way harder then it should. We see this in 60%+ of furnaces.
Check static pressure and airflow. Low airflow can crack your heat exchanger over time—thats a $3,000+ furnace replacement you want to avoid.
Test thermostat accuracy and wiring. If your thermostat says 72 but your house feels like 68, somethings off and we find it.
Replace standard filter (up to 16x25). If you got a custom size or fancy HEPA filter, bring your own or we can quote it.
Test limit switches, pressure switches, and rollout sensors. These shut your furnace down if somethings wrong—they need to work right.
You get a written report of what we found, what we fixed, and whats gonna need attention soon. No suprises—you know exactly whats going on with your furnace.
Most tune-ups take about an hour. If we find problems that need fixing, we explain what we found, quote the repair, and you decide if you want it done. Were hourly techs, not commission salespeople—we dont "find" problems to upsell you.
Chicago winters are brutal, and our housing stock is old. Heres what we run into constantly in neighborhoods like Irving Park, Jefferson Park, and North Center:
These homes have furnaces in crawl spaces or tiny basements. Limited airflow = dirty blower wheels and overheating. We see this pattern in bungalows all over Bridgeport, Portage Park, and Beverly. Tune-ups catch airflow problems before they crack your heat exchanger.
Tip: If your furnaces in a cramped space, annual cleaning is even more important cause dust buildup happens faster.
When temps hit -15 to -25 during polar vortex events, your furnace runs 18-20 hours per day. Weak igniters, dirty sensors, or low gas pressure will cause failures. Tune-ups catch these issues in September when you can fix em at your convience—not in January when everyones furnace dies at once.
Real data: During January 2024 polar vortex, we got 200+ no-heat calls per day. Wait times were 2-3 days for non-plan customers.
Chicago has tons of furnaces from 2005-2010 still running. Heat exchangers crack around year 15-20. We found 3 cracked heat exchangers last fall in older furnaces around Rogers Park and West Ridge. This is a carbon monoxide saftey issue—we red-tag these immediately.
If your furnaces 15+ years old, annual inspections arent optional—there a saftey requirement. We dont mess around with CO leaks.
Some old Chicago homes still have converted coal furnaces (rare, but there out there in neighborhoods like Old Town and Logan Square). These need extra attention cause the combustion chambers were designed for coal, not gas. We always do combustion analysis during tune-ups for these old systems.
If you got one of these relics, budget for replacement soon—parts are getting impossible to find.
Timing matters in Chicago. Schedule too late and your competing with everyone else for the same parts and techs. Heres when smart homeowners in Uptown, Lakeview, and Andersonville call us:
This is when we call our maintenance plan customers to schedule. Beat the rush.
Last November, folks in Garfield Ridge and Mount Greenwood waited 10+ days for parts cause igniters were backordered nationwide. Dont be that guy.
Schedule your furnace tune-up right after Labor Day. Your summers winding down, weathers still nice, and your furnaces sitting there ready to be serviced. This is what smart homeowners in Sauganash, Edison Park, and Norwood Park do every year—they call in early September and get first pick of appointment times.
Look, some HVAC companys use tune-ups as sales opportunities. They send a guy who "finds" expensive problems and pushes new furnace replacements on homeowners who dont need em.
Thats not how we work. Our techs are hourly employees, not commission salespeople. If we find a problem, well show you exactly whats wrong (photos if its hidden), explain what happens if you dont fix it, and quote the repair. You decide.
Most furnaces just need cleaning and maybe a small part like an igniter or flame sensor. Thats what we expect to find. If your furnaces 15+ years old and the heat exchangers cracked, were gonna tell you that too—but were not pushing sales, were explaining saftey issues.
Were in business since 2008 because we dont jerk people around. You get honest diagnostics, fair pricing, and no pressure. Thats it.
Heads up: We dont do scheduled tune-ups for downtown high-rises (Loop, River North, Streeterville, South Loop). Parking is impossible, elevators take forever, and building managment restrictions make routine service inefficient.
However, we DO respond to emergency no-heat calls downtown. If your furnace dies, well come fix it—we just dont schedule preventive tune-ups in high-rises.
For residential homes and small buildings downtown: Call us. We evaluate case-by-case. Most townhomes and walk-ups are fine—its the 30+ story towers that are problematic.
Once a year, ideally in September or October before heating season starts. This catches problems before they become midnight emergencys during a polar vortex. Plus, most manufacturers require annual maintenance to keep warrantys valid—check your paperwork.
Our standard furnace tune-up is $89. If you have both furnace and AC, our annual maintenance plan is $179/year (includes spring AC tune-up + fall furnace tune-up, plus priority scheduling during emergencys and 15% parts discount).
No. Were hourly techs, not commission salespeople. If we find a saftey issue like a cracked heat exchanger, well show you photos and explain why its dangerous. But were not doing high-pressure sales. Most furnaces just need cleaning and minor parts—thats what we expect to find.
We show you exactly whats wrong, explain what happens if you dont fix it, and quote the repair. You decide if you want it fixed. If you approve and we got the parts on the truck, we fix it same visit. If its a big job or we need to order parts, we schedule a follow-up. Your always in control.
You can, but heres the risk: Problems dont announce themselves. Igniters crack slowly over months. Flame sensors get dirty gradual. Heat exchangers develop tiny cracks that grow. By the time you notice somethings wrong, its an emergency at 2 AM when temps are below zero. Tune-ups catch these before they become crisis situations.
Dont wait for the first cold snap when everyones furnace fails at once. Get your tune-up scheduled now while parts are available and we got open appointment slots. $89 tune-up or included in our $179/year maintenance plan with priority scheduling.
Serving Chicago neighborhoods since 2008. No sales pressure. Honest diagnostics. Fair pricing.
