One annual heating tune-up prevents mid-winter breakdowns, keeps your family safe from carbon monoxide, and extends your furnace's life. All Seasons has been maintaining Long Island heating systems since 1968 — our 21-point inspection covers safety and performance.
Most mid-winter furnace breakdowns on Long Island are preventable. A single annual tune-up protects your family, your equipment, and your wallet.
A cracked heat exchanger — invisible to the naked eye — can leak CO into your home. Our annual inspection includes a full combustion safety check and CO test on every visit. This alone makes the tune-up worth it.
The majority of furnace failures have early warning signs a trained tech will catch during a tune-up — before they become a no-heat emergency at 2am in January.
A dirty burner, clogged filter, or restricted airflow makes your furnace work harder and burn more fuel. A clean, calibrated system runs at peak efficiency — reducing your gas or oil bill every month of the heating season.
A maintained furnace lasts 18–20 years. A neglected one may fail at 12–14. Annual tune-ups protect your investment and push back the cost of replacement by years.
Every All Seasons heating maintenance visit is a thorough, documented inspection — not a quick glance and a filter swap. Here's exactly what our certified technicians check on every Long Island tune-up visit.
Carbon Monoxide Safety: A cracked heat exchanger can leak odorless, colorless CO into your living space. Our annual tune-up includes a full combustion safety check and CO test — included on every visit, at no extra charge.
All Seasons offers maintenance agreements for Long Island homeowners who want year-round peace of mind. A maintenance plan covers both your heating and cooling systems — we reach out to you at the right time of year, every year, so you never have to remember to call.

Between annual professional tune-ups, here's what Long Island homeowners can do each season to keep their heating system running safely and efficiently.
"All Seasons has tuned up my furnace every fall for 12 years. They've caught a cracked heat exchanger once and a failing igniter another year — both before the season started. My furnace is 17 years old and still running perfectly. Worth every penny."
"I have a maintenance plan with All Seasons — they call me every fall, show up on time, do a thorough inspection, and leave a written report. Haven't had a single no-heat call in 8 years. The peace of mind going into winter is priceless."
"The tech noticed elevated CO readings during my oil furnace tune-up. Turned out there was a small crack in the heat exchanger. Caught it before it became a serious problem for my family. All Seasons quite literally kept us safe."
