Licensed Plumbing, Heating & Air Conditioning Services Throughout Long Island
Smyth Plumbing, Inc provides residential plumbing, heating, air conditioning, remodeling, and specialty plumbing services, along with commercial repair solutions, throughout Oyster Bay and Long Island. As a licensed and insured company, we handle everything from routine repairs to complete system installations, giving you access to comprehensive property services through a single trusted provider.
You work directly with experienced technicians who understand how different systems interact within your property. Whether you're dealing with a plumbing issue that affects your heating system or planning a bathroom remodel that requires new fixture installation and gas line work, our team coordinates across specialties to ensure everything functions correctly together.
Our service range includes plumbing repairs, drain cleaning and sewer services, water heater installation and repair, fixture upgrades, heating system repair and installation, radiant and hydronic heating, air conditioning services, bathroom and kitchen remodeling, new construction plumbing and HVAC, gas piping, and preventative maintenance. Each service area involves specialized knowledge—water heater sizing differs for radiant heating systems versus standard use, drain layouts affect remodeling plans, and HVAC equipment selection depends on your property's specific heating and cooling load.
When you contact us, you'll receive transparent explanations of what work is needed, why it's necessary, and what options exist for addressing the issue. We provide written estimates before starting any project, so you understand all costs upfront.

Emergency Services Available 24/7 for Urgent Repairs
Plumbing and HVAC emergencies don't follow business hours. We accept emergency calls after hours, providing 24/7 availability for urgent residential and commercial repair needs. Whether you're facing a burst pipe, heating system failure on a cold night, or air conditioning breakdown during summer heat, you can reach our team when you need immediate assistance.
Long Island's aging plumbing infrastructure, seasonal weather changes, and diverse home styles create varied service demands throughout the year. Older properties may have galvanized pipes prone to corrosion, while newer construction presents different considerations for system integration and code compliance. Our technicians work across this range of property types and challenges.
We serve homeowners and businesses throughout Syosset, Huntington, Oyster Bay, Woodbury, Muttontown, Brookville, and Upper Brookville. This coverage area gives us familiarity with local building characteristics, municipal codes, and seasonal patterns that affect plumbing and HVAC systems across different Long Island communities.
What you experience working with Smyth Plumbing, Inc is access to multiple specialties without coordinating between different contractors. If your bathroom remodel requires moving plumbing lines, upgrading fixtures, installing radiant floor heating, and ensuring proper ventilation, we handle all these components as integrated work rather than separate projects. This approach eliminates gaps in responsibility and ensures systems work together as designed.

Our new construction plumbing and HVAC services bring this same coordination to building projects, where proper system design and installation from the start prevents problems later. For existing properties, our preventative maintenance programs help identify developing issues before they become emergencies, extending equipment life and reducing unexpected repair costs.
