Local homesServicesWhere we workCostFAQ
Westbury has some of the oldest housing in our service area. Homes near the village center go back to the early 20th century, surrounded by post-war Capes and ranches. That range means everything from original steam systems to modern heat pumps.
Westbury Homes and Their Heating and Cooling
- Steam heat – older village homes often still run one-pipe steam radiators that need proper venting, pitch and water levels to heat quietly (see boilers & steam heat)
- Hot-water baseboard – common in post-war Westbury homes, often with original zone controls
- No ductwork – most older houses were never built for central air, so ductless mini-splits are the usual way to add cooling
- Oil-to-gas conversions – still common in older homes where gas service is available (see oil-to-gas conversion)

See HVAC installation cost for what drives the number – we give you a firm, written price after a walkthrough.
Westbury HVAC FAQ
Can you keep an old Westbury steam system running?
Usually, yes. Many steam problems – banging pipes, cold radiators, water-level issues – come from vents, pipe pitch and controls rather than the boiler itself. We fix what’s wrong and tell you honestly when replacement makes more sense.
How do I add air conditioning to a house with radiators?
Ductless mini-splits are the most common route – no ductwork required. You keep your radiators for heat, or add heat pump heating as well.
Should I switch my older Westbury home from oil to gas?
If National Grid gas is available on your street and your oil equipment is aging, it’s worth pricing. We’ll cover the tank, the utility process and new equipment in one quote.
