Gas Furnace Repair in Burlington County, NJ

When a gas furnace stops heating, starts cycling on and off, or begins making new noises, the first step is finding out why. Gibson Home Services repairs gas furnaces for homeowners across Burlington County. Owner Ken Gibson, an NJ Master HVACR contractor (License 19HC00370300), has run Gibson since 2009, and every repair starts with a diagnosis, not a sales pitch.

What are the signs your gas furnace needs repair?

The most common signs are no heat, a furnace that turns on and off too often, ignition that fails or keeps retrying, unusual noises, and a blower that runs but pushes cold air through the vents.

• No heat at all. The thermostat calls for heat but the furnace never starts, or it starts and shuts down before the house warms up.
• Short cycling. The furnace runs for a few minutes, stops, and starts again. This wears on parts and leaves rooms uneven.
• Ignition problems. You hear the furnace try to light more than once, or it attempts to start and then locks out.
• New or louder noises. Banging at startup, squealing, rattling or humming that was not there last season are worth having looked at.
• Cold air from the vents. The blower runs, but the air coming out is cool. The fan may be running without the burners lighting, or a safety control may be stopping the heating cycle.
• Rooms that never feel warm. A furnace that runs constantly while the house stays cool can point to an airflow or equipment problem.

What you can safely check yourself is limited: confirm the thermostat is set to heat and set above the room temperature, and check that its display is on and its batteries, if it uses them, are not dead. Please leave the furnace panels and cabinet closed. Anything beyond those simple checks is a job for a licensed contractor.

What should you do if you smell gas or a CO alarm sounds?

Treat either situation as a safety issue first and an HVAC issue second. Get out of the home, then call for help from outside.

If you smell gas or a rotten-egg odor, leave the home now, do not touch light switches, the thermostat or any controls, and call the gas utility or 911 from outside.

If a carbon monoxide alarm sounds, get everyone out of the home and call 911 from outside. Carbon monoxide is odorless.

Once the utility or fire department has made the home safe, call us to schedule a furnace diagnosis.

How does Gibson diagnose a furnace problem?

We diagnose first. Ken looks at how the furnace starts, runs and shuts down, finds the cause of the problem, and explains what he found before any repair work is authorized.

A furnace repair visit generally follows this order:

• Listen to you. When did the problem start? Does it happen every cycle or only some of the time? Has anything changed recently?
• Watch the system run. Many furnace faults only show up during a heating cycle, so we observe the sequence from the thermostat call to the blower shutting off.
• Find the cause. A symptom like short cycling can have more than one cause. We look for the actual fault rather than replacing parts until the problem goes away.
• Explain your options. You get a plain explanation of what we found and what we recommend, in terms that make sense without an HVAC background.

How does furnace repair pricing work?

Gibson uses flat-rate pricing for repairs. You see the price of the repair before any work is authorized, so there is no running clock and no surprise at the end.

The standard non-member service fee is $125. Comfort Club members pay a reduced service fee and receive a repair discount based on their plan level, so it is worth looking at the Comfort Club plans if you want ongoing care for your system. The right price depends on what the diagnosis finds, and you see it before any work starts.

What warranty comes with a furnace repair?

Gibson repairs carry a 90-day labor warranty. Replacement parts are covered by the manufacturer's part warranty, as provided by the manufacturer.

If something related to our work is not right after a repair, call us. Legitimate callbacks related to Gibson's work take priority on the schedule.

Which furnace brands does Gibson repair?

We repair all major brands of gas furnaces, subject to normal parts availability and serviceability. You do not need to own an Amana furnace for us to work on it.

Some older furnaces use parts that are no longer made or are hard to source. If that is the case with yours, we will tell you up front and explain what it means for the repair. You can read more about the equipment we install and service on our gas furnaces page.

Should you repair or replace your furnace?

Often, a repair is the right answer. We will tell you when your furnace is worth fixing, and we will tell you when it may not be. There is no single age or dollar figure that decides it for every home.

The decision usually depends on the furnace's age and repair history, the cost of the current repair, how well the system keeps the home comfortable, parts availability and how long you plan to stay in the house. If replacement does make sense, Ken can walk you through good, better and best options on a free replacement estimate. See furnace replacement for how that process works.

Can regular maintenance prevent furnace repairs?

Maintenance cannot prevent every breakdown, but a pre-season tune-up gives us a chance to spot wear and minor issues before the heating season puts the furnace to work.

Silver and Gold Comfort Club members receive two maintenance visits a year. Learn more on our furnace maintenance page.
