Serving Lemont, IL
HVAC Services Lemont, IL
Heating and cooling repair, new system installation and 24/7 emergency service for Lemont homes – from historic downtown houses to newer hillside subdivisions.
Heating and Cooling Help for Every Lemont Home
Homeowners searching for reliable HVAC services in Lemont face a mix few suburbs can match. Lemont grew up as a quarry and canal town along the I&M Canal and the Des Plaines River, so older homes near the historic downtown sit just a few minutes from newer subdivisions built on the hills and bluffs above the valley.
New Comfort Heating and Cooling provides full HVAC services Lemont IL residents depend on – furnace repair and replacement, AC repair and installation, maintenance and 24/7 emergency service. We are based in Justice, close enough that Lemont is part of our regular southwest suburban route.
HVAC Services Lemont Families Rely On
Furnace Repair & Replacement
Older Lemont homes may have furnaces tucked into tight, low basements, while newer houses often run high-efficiency units with PVC venting. We handle Lemont furnace repair on every brand and recommend replacement only when it truly makes sense.
AC Repair & Installation
Humid summer air settles in the river valley, and a struggling air conditioner leaves the whole house sticky. We take care of Lemont AC repair – from failed capacitors to refrigerant leaks – and install correctly sized new systems.
24/7 Emergency HVAC
Heating problems rarely wait for business hours. If your furnace quits overnight in January or the AC fails during a July heat wave, call us 24/7. We get a technician to your Lemont home as quickly as possible.
Seasonal Tune-Ups
Regular maintenance keeps older equipment running safely and newer equipment running efficiently. We inspect furnaces in the fall and clean and test air conditioners in the spring, before Lemont weather puts them to work.
Why Lemont Homeowners Call New Comfort
Lemont is not a flat, grid-street suburb. Homes step up and down the hillsides, basements may be fully underground on one side and walk-out on the other, and some streets near downtown have houses more than a century old. Each of those details changes how heat and air move through a house.
We have worked across the southwest suburbs since 2013 and service all major brands. Our technicians take time to understand how your home is laid out before recommending a repair, a duct change or new equipment.
You get straightforward answers, the price before the work begins and no pressure to replace something that can be fixed. Free estimates and financing options are available on new systems.

HVAC Services Lemont Homes Need, Old Town to New Subdivisions
Historic homes near downtown. Houses near Main Street and the canal were often built before forced air existed. Some still heat with boilers and radiators; others had ductwork added decades later through closets and chases. Lemont HVAC work in these homes takes patience – limited space, plaster walls and stone foundations all shape the plan for a new furnace or central air.
Mid-century and 1970s-1990s neighborhoods. Ranches, raised ranches and two-stories from these decades usually have ductwork sized for heating first. Adding or upgrading central air without checking the ducts can leave upstairs rooms warm and the system loud. We test airflow before recommending equipment.
Newer hillside subdivisions. Many newer Lemont homes have walk-out basements, vaulted ceilings and large window walls facing the valley. These open layouts gain heat quickly in summer and lose it fast in winter. Two-stage equipment, zoning and proper return placement make a big difference in comfort.
Common Lemont Furnace Repair & AC Repair Problems
Furnace Locks Out on Windy Nights
Homes on exposed hilltops take the full force of winter wind. Drifting snow can block low PVC vent pipes, and a weak inducer motor or failing pressure switch tends to show up on the coldest, windiest nights. Clear the pipes after storms, and if the problem keeps coming back, schedule Lemont furnace repair so we can check the venting and pressure switch.
Cold Rooms Over a Walk-Out Basement
In homes built into a slope, the rooms above a walk-out lower level often run colder than the rest of the house – a very common Lemont HVAC complaint. The cause is usually duct design, not a weak furnace. Sealing and balancing the ducts, or adding a return, often solves it without new equipment.
Sticky Air Even With the AC On
Humidity from the river valley and canal corridor means an air conditioner has to remove a lot of moisture. An oversized unit cools quickly but shuts off before drying the air, leaving rooms clammy. Low refrigerant or a dirty coil does the same. Proper sizing and a tune-up prevent many Lemont AC repair calls.
Outdoor Unit Buried in Leaves and Seeds
Lemont has plenty of mature trees, especially on older streets and wooded lots. Leaves, seeds and cottonwood fluff collect on the condenser coil and choke airflow. Keep two feet of clearance around the unit, and call for Lemont AC repair if it hums but the fan will not spin.
Heating for Garages, Workshops and Outbuildings in Lemont
With larger lots on the edges of town and plenty of older outbuildings, many Lemont properties have detached garages, workshops or pole buildings that need heat in winter. A ceiling-hung gas unit heater, like the one in this photo, keeps a work space usable without tying into the house system.
Proper installation matters: clearances to combustibles, correct venting, a dedicated gas line and a thermostat placed away from drafts. We size the heater for the space and explain how to keep it running safely. A quick inspection each fall – burner, heat exchanger, flue and gas connections – helps a shop heater last for many winters and keeps carbon monoxide risk low.
Whether it is a home furnace or a shop heater, good indoor air matters too. The U.S. EPA has a helpful overview of indoor air quality basics, including carbon monoxide safety for fuel-burning equipment.
A Simple Year-Round Checklist for Lemont Homeowners
Every 1-3 months: look at the furnace filter and swap it when it turns gray. Older homes with stone foundations and dusty basements can load a filter faster than you might expect, and a clogged filter is a leading cause of Lemont furnace repair and frozen-coil calls.
Spring: rake leaves and seed pods away from the outdoor unit, trim back shrubs, and run the AC on the first warm day to make sure it cools. A spring tune-up costs far less than an emergency Lemont AC repair in the middle of July.
Fall: schedule a furnace inspection, test carbon monoxide alarms, and clean or replace the humidifier pad. If you have a garage or shop heater, have it checked at the same visit.
Winter: keep vent pipes and the outdoor unit clear of drifted snow, especially on hillside lots where wind piles it against the house. If anything seems off, our team is a phone call away for Lemont HVAC help around the clock.
What to Expect From a Lemont HVAC Service Visit
When you call (708) 717-9995, we ask a few quick questions about what is happening and set a time that works for you. For no-heat or no-cooling emergencies, we dispatch as soon as possible, day or night. Tell us about anything unusual you have noticed, such as a burning smell, water near the furnace or a breaker that keeps tripping.
Every visit starts with testing, not guessing. The technician diagnoses the problem, explains it in plain language and gives you the price before any work starts. Many repairs – igniters, flame sensors, capacitors, contactors, blower motors – are completed on the first trip. To see the other towns we cover, visit our areas we serve page.
If your equipment is near the end of its life, we will say so honestly and lay out repair versus replacement side by side. Our post on the most common HVAC system failures explains which problems are worth watching for between visits.
Repair or Replace? Straight Answers for Lemont Homeowners
The right choice depends on the age of the system, the cost of the repair, how often it has failed and how comfortable your home is. A 9-year-old furnace with a bad igniter is an easy repair. A 20-year-old furnace with a cracked heat exchanger needs to be replaced for safety.
Older air conditioners that use R-22 refrigerant are a common turning point. That refrigerant is no longer produced, so a major leak often makes replacement the better value. For a deeper look, read our guide to what to consider before AC replacement.
Either way, you receive a clear written price, free estimates on new equipment and financing options if you need them. That is the standard we hold for every job, and it is what HVAC services Lemont homeowners deserve.
