Barrington winters are demanding, and the large estate homes and multi-zone heating systems common in this Cook and Lake County community require a repair team that understands both complex configurations and older equipment. When a furnace fails mid-winter in Barrington, the consequences spread across a home quickly. Leith Heating and Cooling arrives prepared for exactly that scenario.
We diagnose correctly the first time, give you a firm price before any work starts, and back the repair with a full guarantee.

We find the root cause and fix it — not just the symptom that brought us there.
A furnace failure in a Barrington home in January or February is a genuine emergency. Large homes lose heat fast, and family members, pets, and pipes are all at risk when temperatures drop inside overnight. Leith Heating and Cooling prioritizes emergency calls throughout Cook and Lake counties with technicians ready to respond.
We carry components for the most common furnace failures and resolve most emergency calls in a single visit. Call us the moment your system stops working — every hour matters in a cold house.

If you are wondering whether your furnace shows signs of trouble — noises, short-cycling, uneven heat — those are all things we investigate as part of every diagnostic visit.
A homeowner in Barrington called us in early February after her furnace had been shutting off on its own every hour or so. Our technician found a cracked heat exchanger triggering a safety limit switch — a serious issue that should never be ignored. He explained the risk clearly, provided options, and had the exchanger replaced the same day. The home was heating reliably again before temperatures dropped that night.
Barrington homeowners choose Leith because we combine certification with the kind of honesty and accountability a local family business is built on. Here is what we deliver:

Leith Heating and Cooling provides furnace repair throughout Barrington and the surrounding Cook and Lake County communities. We regularly serve Inverness, South Barrington, Deer Park, Lake Zurich, Hoffman Estates, Palatine, and North Barrington. Whether you are in an established estate neighborhood or a newer development near the village center, our team can reach you quickly.
Banging sounds on startup can indicate delayed ignition, a dirty burner, or duct expansion issues. Persistent or loud banging should not be ignored. We recommend having a technician inspect the system before continuing to operate it.
Annual maintenance in fall is the standard recommendation. A pre-season tune-up catches failing components before the first hard freeze and keeps your system running safely and efficiently through the coldest months.
