Oil and propane delivery, heating, AC, and water heaters from one local team.
Darien is a coastal Fairfield County town squeezed between Norwalk and Stamford, framed by Long Island Sound and the Five Mile River. Tokeneke, Noroton, and Long Neck Point are the waterfront neighborhoods; the Boston Post Road and Post Road / Tokeneke Road corridor carries most commercial life.
It's a Metro-North commuter town with two stations (Darien and Noroton Heights), a celebrated school system, and a lot of historic colonial housing stock — much of it still on heating oil delivered by independent CT companies like Levco.
Levco trucks have served Darien for 46+ years.

“I recently booked Levco for seasonal service and cleaning of my two AC units. The tech arrived promptly and did an excellent job. Levco is always professional and courteous, and so easy to work with.”
Connecticut's heating season generally runs October through April, and the phones light up twice: at the first hard freeze and again during the January cold snaps. Booking a tune-up in late summer or early fall gets the work done before that rush, when scheduling is easy. Cooling equipment is best looked at in spring, ahead of the first humid stretch.
Our trucks run out of Trumbull, CT, so this town sits on an established Fairfield County route rather than a one-off trip. Automatic delivery pairs your home's usage history with daily temperatures — and, on propane tanks, a wireless monitor reporting the real level — to schedule a fill before the tank draws down. That's how every Levco propane account runs, and it's what we recommend for oil too.
Wooded and coastal Fairfield County neighborhoods lose power to nor'easters, summer thunderstorms and hurricane remnants. Oil and propane heating systems still need electricity to run, so a standby generator — usually fueled by propane — is what keeps heat, water and refrigeration going through an outage. Heading into storm season with a full tank matters more than the size of the tank, because roads and driveways can stay impassable for a day or more.
Repair usually wins when the system is under roughly 15 years old, has been maintained, and the fix is a small fraction of replacement cost. Replacement usually wins when the equipment is past its expected life, needs something major like a heat exchanger, or has failed in consecutive seasons. Our technicians will tell you honestly which side of that line you're on, and the call is yours to make.
Much of Fairfield County's housing stock went up before central air, so older homes often run oil or propane boilers with cast-iron radiators or baseboard, while newer builds and additions lean on warm-air furnaces with ducted AC. Homes with no ductwork are often cooled — and sometimes supplementally heated — with ductless mini-splits added room by room. We service and replace existing central AC and install and service mini-splits, along with heating equipment, water heaters, and pool heaters. For generators installed by another contractor, we can run the propane line and supply the fuel.
Three come up again and again: skipping the annual tune-up and only calling once the system quits; letting a tank run to the bottom, which pulls sediment into the burner and turns a delivery into a restart visit; and pressing the burner reset button over and over, which floods the chamber. Filters are the fourth — a clogged one chokes airflow, trips the high-limit switch, and looks exactly like a broken furnace.
