Boiler Repair and Replacement

Boilers heat through hot water or steam and remain common in older Somerset and Union County housing stock. Trouble usually announces itself as low system pressure, water pooling near the unit, banging or kettling from mineral buildup, uneven heat between zones, or a zone valve that has stopped responding.

Because a boiler is a hydronic system, the diagnostic path is nothing like forced-air work. A technician who approaches it as if it were a furnace will generally miss the cause.

Gas Furnace Repair and Installation

Gas furnaces are the most common heating system in Central New Jersey homes, and most failures trace back to a short list of components: the ignitor, the flame sensor, the blower motor, the limit switch, or the heat exchanger.

The heat exchanger is the one that matters most. A cracked exchanger can allow combustion gases into the living space, and it is a replacement decision rather than a repair. Installing a new furnace also means confirming the correct size for the house instead of matching whatever was there before, because an oversized furnace short-cycles and an undersized one never catches up on the coldest nights.

Heat Emergency Service, 24 Hours a Day

When your heat fails on a cold winter night, it is not just an inconvenience; it is an emergency. The house cools faster than most people expect, pipes are exposed to freezing, and no family should be waiting until Monday morning in a cold home.

Fast Lane Plumbing & HVAC answers heating calls 24 hours a day, seven days a week, 365 days a year. No-heat calls are triaged on the phone so the technician arrives already carrying the parts the symptoms point toward, which is often the difference between a same-visit repair and a return trip.

Water Heaters and Tankless Combination Systems

Hot water and space heating overlap more than most homeowners realize, and on combination systems they run off the same appliance. We service and replace tank water heaters, tankless units, and tankless combi systems that handle both domestic hot water and hydronic heat.

Recent installations include Bradford White and AO Smith units with the code upgrades that accompany them, including new ball valves, gas cocks, and bonding wire.

Heating System Maintenance and Efficiency Upgrades

Most heating failures give warning before they become emergencies. Annual maintenance catches the worn ignitor, the drifting gas pressure, and the filter that has been starving the blower since spring.

Replacing an aging system is also an efficiency decision. A newer, correctly sized heating system runs less to hold the same temperature, and the reduction in monthly fuel use offsets part of the replacement cost over the life of the equipment. How much depends entirely on what is being replaced and how the house is built, which is a conversation worth having before you buy rather than after.

We handle heating and cooling for the same properties, so the spring AC maintenance and the fall heating check happen with one call to a company that already knows the equipment. We also install whole-home humidifiers, including Aprilaire units, which matter more during a dry New Jersey heating season than most homeowners expect.

 Equipment Brands and Warranties

We are not tied to a single manufacturer. The recommendation starts with the house, the fuel type, the venting, and the budget, and equipment gets matched to that rather than working backward from one brand’s catalog. Homeowners who want a specific make can usually have it.

Warranties are available on boilers, gas furnaces, water heaters, and other equipment we install, so the product itself is covered. Ask for the specific terms on the unit being quoted, because coverage varies by manufacturer and by model.

Heating Service Areas Across Central New Jersey

Our home base is Somerville, NJ 08876, and the fastest response goes to Somerville and the surrounding Somerset County towns. We also take heating work across Union, Hunterdon, Middlesex, and Morris counties.

If you are outside the areas we serve, call and ask. Availability depends on the day and the nature of the job, and an emergency no-heat call is handled differently from a planned replacement.

Heating Repair Questions We Get Asked 

What is the difference between a boiler and a furnace?

A furnace heats air and pushes it through ducts to vents in each room. A boiler heats water and circulates it through pipes to radiators, baseboard, or in-floor tubing. Furnaces are forced-air systems and share ductwork with central air conditioning. Boilers are hydronic and use no ducts at all. The difference matters for repair because the two fail in entirely different ways, and it matters for replacement because converting from one to the other is a far larger project than swapping like for like.

Should I repair my heating system or replace it?

Two factors usually decide it: the age of the system and the cost of the repair relative to what the unit is still worth. A system past fifteen years needing a major component is a different calculation from a five-year-old furnace with a failed ignitor. When a system is beyond repair, we handle the replacement, and we will tell you which situation you are in before you spend money on a repair that will not hold.

How quickly can someone get here for a no-heat call?

Heating calls are answered 24 hours a day, seven days a week, 365 days a year, and emergency no-heat calls are prioritized ahead of scheduled work. Call (908) 300-8183 and we will tell you what the timing actually looks like.

Do you work on every brand of heating equipment?

We service a wide range of makes and models across boilers, gas furnaces, and water heaters. If you know the brand and model number, have it ready when you call. It lets us bring the likely parts on the first visit.
