Six decades of installs across the Hudson Valley back every system we put in, with a licensed crew behind every job.
Stop worrying about whether the system will start when you need it.
Get a straight answer on what is wrong without the technical jargon.
Avoid repeat visits when the diagnosis is right on the first try.
Patching the same HVAC problem two summers in a row is the kind of thing that steadily eats away at your bank account and patience. A capacitor here, a coil cleaning there, a refrigerant top-off the next year, and the system still struggles when the weather turns.
Once equipment is over 15 years old, repair costs start to outweigh its value. Mazzacone Plumbing & Heating has spent more than six decades replacing dated equipment in Westchester homes with installs that hold up through humid Augusts and freezing Januaries.
Our licensed crew sizes equipment to your home, pulls the New Castle permits when needed, runs combustion and airflow checks at startup, and stays available after the install closes out. The phone gets answered by Robert Mazzacone directly so you’re always in good hands.
Most Millwood homeowners do not start the summer thinking about a new air conditioner. The decision usually comes after the existing system runs all day on a Saturday in July without bringing the temperature down, or after the third refrigerant top-off in two years stops holding.
Once a central AC system reaches 15 years old, it’s often not worth repairing. Every project we install starts with a load calculation that accounts for square footage, insulation, window exposure, and ductwork.
We match the new condenser and coil as a system, set a fresh pad, and verify charge and airflow at startup. Older homes near the Briarcliff Manor border and newer condo developments off Route 100 each call for different sizing.
Replacements, repairs, and seasonal service across town.
A no-cool call usually traces to one of a handful of common parts: a capacitor, a contactor, a low charge, or a clogged coil. Our techs work through the system, pinpoint the failure on the first visit, and price the repair before tools come out.
Older Millwood homes without ductwork often pick mini splits instead of tearing through plaster to add ducts. We design single and multi-zone systems with cold-climate inverters, and run line sets along clean trim lines.
Furnace replacement done properly is more than a box swap. We review venting, gas line sizing, return air, and combustion air, then install sealed-combustion equipment that vents through PVC and runs quieter than what came out of the home.
January is the worst possible time to wait three days for a heating tech. Our licensed crew responds within the same week, runs a full diagnosis on ignition and gas valve components, and gives flat-rate pricing on the fix up front.
Maintenance keeps your equipment under warranty and catches small failures before they grow into emergency calls. Visits include combustion analysis, coil cleaning, refrigerant checks, electrical inspection, and a written report on file.
Upgrading from a basic thermostat to a Wi-Fi or learning model brings remote control, smart scheduling, and clear visibility into how your system runs. We confirm wiring, install the new unit, and pair it so the features get used.
Here is how a Mazzacone HVAC project moves from start through to finish.
Call our office or send in the request form, and our team will get back to you the same day to discuss what’s going on with your HVAC system.
A technician walks the home with you, runs a full diagnosis on site, and follows up with a written estimate the same day.
On install day the crew shows up on time, lays floor protection, and tests the new system under load before walking you through it.
These come up most often in Millwood homes, from older construction near the Briarcliff border to condo developments off Route 100.
Millwood took its current name in the 1880s when the railroad station opened on what had been the Sarlesville hamlet. Sarles’ Tavern still anchors the area, and the streets around it sit minutes from the Chappaqua Metro-North stop.
Mazzacone Plumbing & Heating covers cooling diagnostics, mini-split installs, furnace swaps, and seasonal tune-ups across town.
Homeowners come back because the same family-run team that did the work years ago is still here. Larger projects route through the New Castle Building Division on South Greeley Avenue.
Beyond Tarrytown, we cover HVAC work in nearby Westchester cities, villages, and hamlets year-round.
