Our Services
HVAC Installation, Maintenance & Repair in Libertyville
Heating & Furnace
Furnaces, boilers, and heating repairs across Libertyville. Boiler work is its own skill set, and a lot of companies would rather sell you a conversion than service what you have. If your radiators are working well, we'll tell you that.
Air Conditioning
Repairs, replacements, and spring tune-ups. If your home was built without ductwork, cooling it doesn't have to mean tearing up ceilings — ask us about ductless and high-velocity options.
Water Heaters
Gas, electric, and tankless. In older homes, a water heater replacement is often the moment you find out the venting no longer meets code. We'll flag that before it becomes a surprise.
Indoor Air Quality
Older houses breathe differently than new ones. Dry winter air, uneven humidity, and dust from decades-old ductwork all have fixes.
Commercial HVAC
Storefronts along Milwaukee Avenue, offices, and light industrial space. We service and install commercial systems throughout the area.
Emergency Service
Breakdowns don't wait for business hours. Call us any time.

What we see in Libertyville homes
Boilers and radiators
A good cast-iron boiler can run for decades, and plenty of Libertyville homes still have one doing honest work. The question is usually whether it's worth maintaining or whether efficiency losses have caught up with it. Those systems need someone who knows hydronic heat — bleeding air from radiators, checking expansion tanks, diagnosing circulator pumps — not someone whose first instinct is to quote a full forced-air conversion. We'll walk you through both paths and what each actually costs.
Cooling a house with no ductwork
If your home predates central air, you have real options beyond window units. Ductless mini-splits handle room-by-room cooling without any duct runs. High-velocity systems use small flexible tubing that fits through existing wall cavities, which is often the better choice in a house where you don't want visible indoor units. Both are more involved than a standard AC swap, and both are worth understanding before you commit.
Second floors that never cool down
Common in older two-stories, and it's usually not a broken air conditioner. More often it's ductwork that was added later and undersized, insufficient return air upstairs, or an attic that's radiating heat down through the ceiling all afternoon. The fix depends on which it is, and figuring that out is worth more than a bigger unit.
Mature trees
Libertyville's tree canopy is one of the nicest things about the village and one of the hardest things on outdoor equipment. Leaves and seed debris pack into condenser coils, and a unit tucked into heavy shade against a fence may not be getting the airflow it needs. Keep two feet of clearance on all sides, and expect to rinse the coil more often than a homeowner on an open lot would.
Two different replacement scenarios
In the newer subdivisions, the systems installed with the house are now in the 20-to-25-year range and reaching end of life more or less together. That's a planning conversation — better to schedule a replacement in the fall than handle a failure in February. In the older homes, the question is usually whether to keep restoring what's there or modernize, and the honest answer depends on the condition of what you have.
