Get straightforward answers about your HVAC system.
Hear back the same day you reach out, with no callback runaround.
Trust a tech who has worked through the same issue many times.
Hiring an HVAC contractor often feels like rolling dice. One company quotes high and stops returning calls the day after the install, another sends a different tech every visit, and a third blames the equipment when something fails on warranty. None of that is what you signed up for.
Mazzacone Plumbing & Heating has been working in Hawthorne and the surrounding Mount Pleasant hamlets for more than six decades, with a licensed crew that explains the work in plain language and stays reachable when something needs attention.
The neighbors who hired us a decade ago still hire us now, and that is the only review that matters in this business.
Furnaces typically give homeowners a clear warning before they fail, but those warnings are easy to miss. Strange noises during ignition, uneven heat between rooms, a pilot that needs relighting too often, or a gas bill that climbs sharply year over year all point to a system that needs replacing.
Mazzacone Plumbing & Heating replaces old furnaces across Hawthorne with high-efficiency, sealed-combustion units that cut fuel bills, run quieter, and vent through PVC instead of leaning on an aging chimney.
Every replacement starts with a full review of your gas line sizing, return air paths, and combustion air supply before any new equipment gets ordered. We confirm everything is in working order after the install wraps up.
From a stuck thermostat to a full system swap, we cover it.
Most AC failures trace to a few parts that are easy to spot once a tech is at the unit. Capacitors, contactors, refrigerant leaks, and clogged condensate lines top the list. We diagnose in one visit and price the repair before any work begins.
Plenty of Hawthorne homes have a finished attic or back room the central system never reaches. Mini splits solve that with a single outdoor unit feeding multiple zones. We design the layout and hide line sets cleanly.
Finishing a furnace replacement in a single day is the standard when planning is solid. We handle gas line sizing, venting changes, and chimney liners up front, then install equipment that vents through PVC and hits ratings the old unit never could.
A furnace that won’t fire on a cold night is not a problem that fixes itself. Our techs handle ignition, gas valve, blower motor, and control board faults the same week you call. Pricing is flat-rate and given up front.
Skipping yearly maintenance is the easiest way to void a manufacturer warranty without realizing it. Our visits include combustion analysis, coil cleaning, refrigerant charge verification, and electrical inspection.
Replacing an old mercury or basic digital thermostat with a Wi-Fi or learning model gives you remote control, smart scheduling, and visibility into how the system runs. We confirm wiring, install the new unit, and pair it with your equipment.
The path from your first message to a working system, in three steps.
Reach us by phone or the request form on the site. We schedule the visit within a day or two and confirm the time with you ahead.
A licensed tech walks the home, takes measurements, and provides you with an estimate to repair or replace your HVAC system.
Crews show up on time the day of install, lay down protection, complete the work to code, and walk you through the new system.
These issues come up most often in Hawthorne homes, regardless of equipment age, fuel type, or how long since the last service visit.
Hawthorne grew around an 1880s railroad stop, and the historic Railroad Station still stands on the National Register. Most homes nearby date back to the postwar build-out, with newer subdivisions along Bradhurst Avenue.
The older stock often runs on equipment that was never sized for today’s standards, which is where most of our AC replacement, furnace replacement, and mini split work comes from.
Hawthorne homeowners come back because we answer the phone, give straight pricing, and stand behind the work, year after year.
Outside of Hawthorne, we cover HVAC work in nearby Westchester cities, villages, and hamlets.
