Half the house is comfortable. The other half is the job.
Horizon Gate works on heating, cooling and ventilation for houses and businesses on the north shore. Most of what we are called about is not a broken machine — it is a building where the air does not go where it should.
Heating, cooling, and the ducts in between
Gas and oil heating, boilers and radiators, central air and heat pumps, and the ductwork that decides whether any of it reaches the room you are standing in.
Heating
Gas and oil furnaces, boilers and radiators, and heat pumps. Serviced with a combustion analyser and a written result, diagnosed from the cheap end, and replaced only when the readings say so.
Cooling
Central air, heat pumps, ductless and window units in the houses that still use them. Charge measured rather than topped up, and sized from a calculation rather than from what came out.
Ducts & airflow
Static pressure, register-by-register airflow, leakage into attics and crawlspaces, and returns that were never big enough. This is where most comfort complaints actually live.
Ventilation
Bathroom and kitchen extract that actually terminates outside, extract for commercial kitchens and workshops, and the make-up air that has to replace what you throw away.
Zoning
Dampers, a second thermostat and a controller — where the building and the duct system can actually carry it. There is a whole page on this site about when it is and is not the answer.
Maintenance
Annual on houses, twice a year on premises, with readings recorded per unit so the file shows a trend rather than a stack of invoices.
“Should we zone the house?”
It is the most common question we are asked in Huntington, and in three cases out of four the honest answer is “possibly, but not yet”. In the fourth it is simply yes.
Six checks, in a different order for each complaint
Upstairs baking in August is a different problem from upstairs freezing in February, even though they sound like the same complaint and get sold the same solution. Tell the page what is actually wrong and it puts the six checks in the order that suits it — and puts zoning where it honestly belongs in that order.
Why it is not just a sales page
Zoning a house with leaking attic ducts and an undersized return produces an expensive system that still cannot keep the back bedroom warm, because the air was never getting there. Where that is the situation the page says so, in that order, before it mentions dampers.
Where two people genuinely want different temperatures in different parts of the house, zoning goes first — because nothing else solves it.
Houses and premises, both properly
Homes
Colonials, capes, ranches and split levels, plus the extensions and finished attics that were added to them — which is where most of the uneven-temperature work comes from. Oil and gas both, because this part of Suffolk County has plenty of each.
Businesses
Village shops, restaurants, professional suites, clinics and small industrial units. Rooftop and split systems, extract with make-up air, planned maintenance with a record per unit, and fit-out work coordinated with the trades that come before us.
What is not on this website
A price
A stuck damper and a failed compressor are not the same visit. You get a fixed figure on the phone once we know what is installed.
A response time
We will not promise two hours on the first cold night of the year when the whole village has lost heat.
A saving
“Cut your bills by a third” depends on your house, your habits and your fuel. Nobody can know it from a web page.
Asked often enough to answer here
Should I zone my house?
Sometimes, and it depends entirely on what is actually wrong. If two people want two different temperatures in different parts of the house, zoning is the only thing that solves it and it should go first. If the second floor bakes in August, zoning usually comes last — the ducts in the attic and the roof above them are beating the system before it gets there, and dividing the air you have does not create more of it. There is a page on this site that puts the six checks in the right order for each complaint.
Upstairs is freezing in winter. Is the furnace too small?
Probably not, and this one is worth thinking about: heat rises, so a second floor that is colder than the first in January is behaving oddly. That usually means something specific — a damper, a closed or crushed branch, or a return that cannot get air back — rather than a capacity problem. Those are the cheap checks and they have a good hit rate.
Do you work on oil?
Yes. Burner service, nozzles and electrodes, combustion testing, and oil furnaces and boilers. What we do not do is tank work — testing, removal, and anything to do with a leak are specialist jobs with their own regulations, and we will tell you to get a tank specialist rather than taking it on ourselves.
Should I close the vents in rooms I do not use?
Generally no. Closing supply registers raises the pressure across the whole duct system, which pushes more air out through the leaks and makes the blower work harder. On a modern high-efficiency furnace it can trip the limit switch. It rarely helps and it sometimes does harm.
Why is there no price list on the site?
Because the same description covers a two-hour job and a two-day one depending on the house. Adding a return in an open basement and adding one through a finished ceiling are not the same work. You get a fixed figure on the phone once we know what is there.
