Furnace Repair in Randolph, NJ

Numerous parts make up your home’s furnace, and many can wear out or break without you noticing. Unfortunately, the root cause of your broken furnace may not be obvious at first glance. The Comfort Specialists furnace repair team has experience working with many furnace makes and models, so we can quickly diagnose and repair the problem and restore heat to your home.

Reasons Your Furnace Isn’t Working

Your furnace system may need repairing for many reasons, but the following are the most common problem areas we fix for Randolph homeowners.

Button

Malfunctioning Thermostat

The thermostat starts and stops your furnace system based on your home’s temperature. However, perhaps your furnace system starts but never actually stops, regardless of your home’s room temperature. If so, adjust your furnace system’s fan setting to automatic.

If your furnace system continues to run constantly, you may have a malfunctioning thermostat.
Clogged Air Filters and Vents

Sometimes, dirt and dust build up in your furnace system’s air filters and vents and prevent adequate amounts of air from flowing throughout your home. We suggest changing your furnace system’s air filters and vents at least once every three months to prevent this from happening.
Flickering or Yellow Pilot Light

Your furnace system’s pilot light is supposed to burn as a steady flame and remain constant in color (i.e., blue). If your furnace system’s pilot light is flickering or changing colors (i.e., from blue to yellow), then your furnace system is likely producing excessive amounts of carbon monoxide, which is toxic to breathe. If you notice this, do not hesitate to contact us at Comfort Specialists immediately.

Faulty Heat Exchanger

Your furnace system’s heat exchanger keeps your air and heat flowing separately from combustion byproducts.

If your heat exchanger is cracked or damaged, your home’s air may become contaminated with toxic combustion byproducts. We suggest calling in an HVAC professional to check your heat exchanger and, if needed, replace it to ensure safe air in your home.
Broken Blower Belt

Your furnace system’s blower motor and blower belt turn a fan to circulate heated air throughout your home. Because it is frequently in motion, your blower belt may break down or fray along its edges or even break apart altogether.

Once your furnace system’s blower belt breaks, there is no way for the blower motor to activate the blower fan, which leaves your home’s heated air idle and, thus, your home unheated.
Damaged Limit Switch

Your furnace’s limit switch is the device responsible for activating your furnace system’s blower components when the temperature drops below a certain temperature. This process allows your furnace to match the room temperature it produces with the room temperature you prefer.

However, if your furnace fan continues to run regardless of your home’s room temperature, your furnace may have a limit switch issue that needs to be addressed as soon as possible.

Damaged Ball Bearings

Your furnace system’s ball bearings help reduce friction within your furnace system to ensure that all parts work together seamlessly. Over time, these ball bearings are exposed to wear and tear and eventually break down, causing your furnace system to perform poorly and perhaps even overheat.

If you hear a humming, grinding, or rattling noise coming from your furnace system, chances are you need to replace your furnace system’s ball bearings.

Signs It’s Time to Call for Randolph Heater Repair

In addition to your furnace system needing repair, your heater may also need repair. Consider the following situations that mean it’s time to call Comfort Specialists for heater repair service in Randolph.

Irregular Noises

In addition to hearing a humming, grinding, or rattling noise coming from your furnace system due to worn-out ball bearings, you may also hear a banging, shrieking, or rumbling noise coming from your furnace system. This may be due to a gas explosion, blower belt breakdown, or some other internal furnace system issue.
Short Cycling

Short cycling occurs when your furnace system cuts on or shuts off without reaching specified temperature levels. This may be the result of your furnace system having a limit switch issue, malfunctioning thermostat, broken heat exchanger, or something else. If your heater doesn’t stay on, give us a call at Comfort Specialists, and we’ll send a technician to investigate the issue as soon as possible.

High Electricity Bill
Has your electricity bill increased significantly from one month to the next? Significant increases to your electricity bill when your usage stays the same may be the result of your furnace system experiencing heater-specific issues, such as:
- Gas or air leaks
- Clogged or dirty air vents or filters
- Faulty internal components (e.g., broken blower belt, worn-out ball bearings, faulty limit switch)
Low Heating Output

Your home may have areas that are more or less insulated than others. This results in temperatures in some areas of your home being consistently lower than temperatures in other areas. In response, your furnace system typically distributes heat unevenly throughout your home, leaving your home with an overall lower heating output.

What to Expect During Heater Servicing in Randolph

We strongly suggest scheduling regular heater maintenance to avoid expensive heater or furnace repair down the line. Specifically, consider the following, and for more FAQs regarding heating repair, give our experienced team a call.

Thermostat Calibration

Thermostat calibration aligns your designated temperature setting with your home’s actual room temperature. This process is as simple as obtaining a room temperature reading separately from the reading provided by your furnace system’s thermostat.

You can expect some minor differences in room temperature readings. Still, differences in room temperatures beyond + / - 3 degrees indicate it’s time to recalibrate your thermostat.

Airway Examination

Airway examination involves:

Checking your furnace system’s ventilation ducts

Finding and removing any obstructions causing airflow disturbances

Replacing dirty or broken parts

Combustion Analysis

Combustion analysis refers to testing your furnace system’s heat exchanger to confirm everything is working as expected. Our trained and certified technicians conduct this test using industry-approved tools called combustion analyzers.
