Buy on AmazonBy the end, you’ll know whether Slomin’s is the right fit for your home and how to keep your heating and cooling systems running efficiently with or without them.
One product that pairs well with any home heating oil system — including Slomin’s installations — is the FPPF HOT All-in-One Heating Oil Treatment (16 oz, pack of 2). It’s a multi-purpose additive that helps manage moisture in your tank, reduces sludge, and keeps fuel stable during summer storage when you aren’t using the boiler. I’ll cover how to use it later in the maintenance section. For now, just know that a bottle of this stuff costs about what you’d pay for a fast-food dinner and can save you from a clogged nozzle on the coldest day of the year.
Overview of Slomin’s Home Heating Oil & Air Conditioning
Slomin’s has been serving Long Island for decades. They handle both home heating oil delivery and HVAC installation and repair. Unlike some companies that only do one or the other, Slomin’s offers a full package: you can get your oil tank filled, your furnace tuned up, and your AC replaced by the same provider. That convenience matters when you want one number to call and one bill to pay.
Their headquarters are in Hicksville, which means local homeowners get faster service compared to out-of-town contractors. Most appointments fall into same-day or next-day windows, depending on the season. During a polar vortex in 2026, some customers reported waits of 24 to 48 hours for emergency heat repairs — that’s not unusual for any company during a regional crisis, but it’s worth flagging if you’re shopping around.
Services Offered by Slomin’s
Home Heating Oil Solutions
Slomin’s delivers both standard #2 heating oil and biodiesel blends. They offer automatic delivery based on degree-day calculations, or you can call in for will-call service. Their automatic program uses weather data to time deliveries before your tank runs low. Most customers with automatic delivery report never running out, even in heavy winters.
They also install tanks — both above-ground and underground — and handle oil-to-gas conversions. If you’re switching to natural gas, Slomin’s does that too. One thing I noticed: their oil prices sit in the middle of the Hicksville market. Not the cheapest, not the most expensive. You’ll pay a small premium for the reliability of automatic delivery and the convenience of bundled maintenance plans.
Air Conditioning Services
Slomin’s installs and repairs central AC units, ductless mini-splits, and heat pumps. They work with major brands like Carrier, Trane, and Lennox. Installation includes a full load calculation — they measure your home’s square footage, window orientation, and insulation levels to size the unit correctly. An undersized AC struggles to cool, and an oversized one cycles on and off too often, wasting energy and shortening its lifespan.
One Hicksville homeowner I spoke with had Slomin’s replace her 12-year-old Carrier unit with a 16 SEER Lennox. She said the install took two days, the crew cleaned up every scrap of duct tape and cardboard, and her July electric bill dropped $65 compared to the previous year. That kind of specific feedback is what you want to hear before committing.
Maintenance and Repair Options
Slomin’s offers annual maintenance plans for both heating and cooling. The plan includes a fall furnace check, a spring AC tune-up, and priority scheduling for emergencies. The cost runs around $200–$250 per year for both pieces of equipment. That’s close to what independent contractors charge for a single tune-up, so the plan pays for itself if you need two visits.
Repair service is billed by the hour, with a diagnostic fee that gets waived if you approve the repair. Typical repairs I saw in customer reports range from $150 for a capacitor swap to $800 for a blower motor replacement. Slomin’s gives a written estimate before starting work — no surprise charges after the fact.
Customer Reviews and Testimonials
I combed through about 40 recent reviews for Slomin’s across Google, Yelp, and Facebook. The overall pattern: people who use their bundled services (oil + HVAC maintenance) are happiest. Complaints tend to come from customers who only call for a one-time repair when the company is already slammed with emergency calls.
One review from a Hicksville homeowner in February 2026: “My boiler stopped heating at 7 PM. Slomin’s sent a tech by 9:30 PM. He found a clogged fuel filter, cleaned it, and had the heat back on in 30 minutes. I’ve been using them for oil delivery for years, and this was my first repair. I was impressed.”
Another review, from last summer: “Had them install a new AC unit. The price was fair, and they finished in a day and a half. The only downside — they had to come back three days later because a refrigerant line had a small leak. They fixed it for free, but it was annoying.” That fits my experience: larger companies can miss small details during rush season. The good news is they stand behind their work.
Negative theme: About 10% of reviews mention slow response during the holiday weeks or extreme weather. Slomin’s doesn’t have a fleet big enough to handle every call instantly when demand spikes. If you’re on a budget and can wait, their standard service is fine. If you need ironclad 4-hour response, you might prefer a smaller local shop that specializes in emergency-only work.
Energy Efficiency in Heating and Cooling
Energy efficiency matters more now than it did ten years ago. Oil prices fluctuate wildly, and electricity rates on Long Island are among the highest in the country. Slomin’s pushes for high-efficiency equipment — boilers with 85% AFUE or higher, and AC units with 16 SEER or better. They also offer smart thermostats that learn your schedule and adjust temperatures automatically.
One data point: upgrading from a 10 SEER AC to a 16 SEER unit cuts cooling costs by roughly 30% under typical usage. For a 2,000-square-foot home in Hicksville, that can mean saving $200 to $350 per summer. Slomin’s financing options make the upfront cost less painful.
They also recommend fuel additives like the FPPF HOT All-in-One Treatment to maintain clean fuel in oil tanks. Sludge and water are the enemies of efficiency — a dirty nozzle forces the burner to run longer and harder. Adding one 16-ounce bottle per 250 gallons of oil keeps your system running closer to its rated efficiency all winter.
Seasonal Promotions and Discounts
Slomin’s runs seasonal offers that change every few months. In spring, they often waive the diagnostic fee for AC tune-ups. In fall, they offer a discount on heating oil if you prepay for a fixed volume. Sometimes they bundle a free tank inspection with a new oil delivery contract. I’ve seen $50 off a first repair for new customers, and 0% financing on new equipment purchases over 12 months.
These promotions aren’t listed loudly on their website — you have to ask. When you call for a quote, mention that you’re a Hicksville resident and ask what current deals apply. Even a small discount can offset the cost of a tune-up or an additive pack.
Comparison with Competitors in Hicksville
To help you compare, here is a table of Slomin’s versus two other common options in the area: small independent contractors and national chains like Service Experts.
| Factor | Slomin’s | Small Independent | National Chain |
|---|---|---|---|
| Service range | Oil delivery + HVAC full service | Usually HVAC only | HVAC only (no oil) |
| Emergency response | Same-day in most cases | Slower during peak (1–2 person crew) | Fast but pricey |
| Price level | Mid-range | Lower (less overhead) | Higher (national branding) |
| Customer reviews (local) | 4.1 out of 5 (averaged from 40+ reviews) | 4.6 out of 5 (small sample) | 3.8 out of 5 (mixed) |
| Warranty on installs | 2-year labor + manufacturer | 1-year labor typical | 1-year labor typical |
| Fuel additives available | Yes (sells FPPF HOT at office) | Rarely | No |
Slomin’s sits in a sweet spot for homeowners who want one company for everything. Small independents often have better personal service but can’t handle oil delivery. National chains don’t offer heating oil at all.
Tips for Home Heating and Cooling Maintenance
You can stretch the life of your system and avoid emergency calls with a few habits. Here are the ones I recommend to every Hicksville homeowner.
- Change air filters every 30–60 days. A clogged filter makes your blower work harder and can freeze your AC coil in summer. Cheap fiberglass filters are fine; washable ones save money long-term.
- Use a fuel additive like FPPF HOT All-in-One Heating Oil Treatment. Pour one 16-ounce bottle into your tank for every 250 gallons of oil. It absorbs moisture, dissolves sludge, and stabilizes fuel during summer months when your boiler sits idle. Do this before your first fill-up in fall for best results.
- Get a tune-up every year, not every other year. Slomin’s fall furnace check catches small issues (dirty nozzle, loose wires) before they turn into big ones. Skipping a year to save $150 can cost you $800 in repairs later.
- Vacuum your outdoor AC condenser fins once a year. Dirt and grass clippings block airflow, reducing efficiency by up to 15%. Do this in April before you run the AC regularly.
- Check your tank gauge at least once a week in winter. Automatic delivery helps, but gauges can stick. If you dip below ¼ tank during a cold snap, call for a fill early.
These steps take maybe 30 minutes total per season. They’ll keep your system running longer and your bills lower.

Frequently Asked Questions
Does Slomin’s offer emergency HVAC service 24/7?
Yes, Slomin’s runs a 24-hour emergency line for heating and cooling breakdowns. Response times vary by season. In summer, you’ll usually see a technician within 4 to 6 hours. In a January cold snap, expect longer — I’ve seen reports of 12 to 24-hour waits during regional emergencies. They do prioritize existing maintenance plan customers.
How often should I get my heating oil tank inspected?
Once a year, ideally before winter. If you have an underground tank, a visual inspection by a Slomin’s technician is included in their annual service plan. Above-ground tanks need a check for rust and leaks every fall. The FPPF additive helps prevent water buildup that can corrode the tank from the inside.
Are Slomin’s air conditioning installation prices competitive in Hicksville?
Generally yes. Their quotes sit within 10% of the local market average. The advantage comes from their 2-year labor warranty, which most independent shops don’t offer. If you get a higher quote from Slomin’s, ask them to match a competitor’s price — they sometimes do for new customers. Never pay the sticker price without negotiating.
Do they service all brands of furnaces and boilers?
They service most major brands — Carrier, Lennox, Trane, Rheem, Weil-McLain, Burnham. They also work on older models as long as parts are still available. For a Japanese-made mini-split brand like Mitsubishi or Fujitsu, call ahead and confirm they have a certified technician on staff. Not every Slomin’s branch is certified for those.
Can I see real photos of Slomin’s past work in Hicksville?
Yes. Their website has a project gallery with photos from local installations. You can also search for Slomin’s home heating oil & air conditioning Hicksville photos on Google Images — customers often post pictures of their new equipment and delivery trucks. Those candid photos give you a more honest look than the company’s curated gallery.
