Know the housing stock
Built around a 75-acre private lake since 1955
Loch Lomond began in 1955 when the Arthur T. McIntosh Company dammed the southern branch of Bull Creek to create its 75-acre private lake, and the surrounding subdivision grew to more than 600 single-family homes. The first wave were compact 1,200-square-foot U.S. Steel homes; Briar Construction followed in the 1960s with the larger split-levels and raised ranches most residents live in today (median year built: 1962).
That midcentury housing stock shapes the mechanical work here: original ductwork sized for smaller equipment, additions that outgrew the first furnace, finished lower levels in raised ranches that run cold, and lake-adjacent lots where a failed sump pump is not a hypothetical. Every homeowner also belongs to the Loch Lomond Property Owners Association, which manages the lake, beaches, and dam.
What we fix most in Loch Lomond
Split-level hot-and-cold floors
The 1960s Briar split-levels heat unevenly by design: half-flights of stairs, single thermostats, and ducts that favor the main level. Zoning, duct balancing, or a ductless head in the lower level usually fixes what a bigger furnace cannot.
Lakeside water tables and sump pumps
Homes near the shoreline and the Bull Creek drainage sit on a shallow, wet water table. We test sump pumps, add battery backups, and correct discharge lines before spring melt, not after the lower level floods.
Original equipment past its era
Many Loch Lomond systems are second- or third-generation replacements squeezed into closets sized in 1962. We measure, load-calculate, and quote flat-rate so the new system actually fits the house, not just the closet.

Services we bring to Loch Lomond
Loch Lomond questions we hear most
Do you actually service Loch Lomond, or just greater Mundelein?
Both. Our office is in Mundelein, so Loch Lomond is home turf. Techs are dispatched from minutes away, which matters at 6 a.m. in January.
My split-level's lower floor is always cold. Is that fixable?
Yes. It is the most common comfort complaint in the neighborhood. Depending on the house, we balance or reroute ductwork, add a zone, or install a small ductless head in the lower level. We will give you options with exact flat-rate prices before any work starts.
Can you replace a water heater or sump pump in an original U.S. Steel home?
Yes. The compact utility spaces in the 1950s homes are familiar territory, and we stock equipment sized for them. Battery-backup sump systems are a smart add for lake-adjacent lots.
Are there rebates for upgrading my furnace or AC in Loch Lomond?
Yes. Mundelein homes are in ComEd electric territory and most are Nicor Gas customers, so 2026 rebates cover qualifying heat pumps (up to $2,000 ducted / $1,000 ductless via ComEd), high-efficiency furnaces ($150 to $225), and boilers ($350) via Nicor Gas. We confirm exact eligibility on your written quote.
Do I need HOA approval for HVAC work?
The Loch Lomond Property Owners Association governs the lake and common areas rather than interior mechanicals. Exterior work like a new condenser pad or mini-split line set is typically fine, but we place equipment thoughtfully and can help with any paperwork your street requires.
