Indications Your Heater Needs Repair

When a heating system emits strange odors, intermittently cycles on and off, fails to heat your home, makes a loud racket, or will not turn on, it is time to call a reputable HVAC technician for repairs.

A gas-powered heater that emits a slight odor is often natural and normal. If you are utilizing a heater for the first time in a while, accumulated dirt and dust may be the source of the odor. However, if the odor lingers or worsens, it is advised to be watchful and contact an HVAC technician to inspect the unit. If strong odors do not dissipate over time, there may be a gas leak or anything burning inside the device.

When a heater is operating, the house should heat up rapidly and effectively. If the thermostat is turned all the way up and you are still shivering, there may be a leak in your ducting. This can develop in air ducts running through your crawl space or attic that are generally undetectable. Fortunately, our professionals know where to look and can properly insulate your ducts. We will not allow frigid drafts and electrical waste to ruin your winter!

Changing the temperature abruptly can damage your heating unit and thermostat. When a heater is repeatedly turned on and off, it works harder and consumes more power. Altering your thermostat too frequently can also hasten the deterioration of your heating system’s components, leading to costly repairs and replacements!

A heater should be simple to activate. If your unit has difficulty starting, it is time to troubleshoot the issue. This could be due to a dirty or malfunctioning pilot, an issue with the natural gas line, disconnected wiring, dead batteries, or a broken thermostat. Installing a thermostat in direct sunlight, near hot appliances, or near vents should be avoided. This may result in inaccurate temperature measurements.

Checking the pilot light is a straightforward and reliable method for detecting gas imbalances. A healthy pilot light should have a bluish hue, indicating that the ratio of gases is balanced. The presence of a yellow pilot light is cause for alarm. A yellow pilot light typically indicates an excess of carbon monoxide and/or a ventilation issue. Yellow pilot lights indicate potentially serious health problems and require immediate professional intervention.

When a heater makes regular noises, it is important to pay attention to the type of sound that is being produced. This may reveal the origin of your issue:


  • Belt or fan problems typically screech.
  • Loose components in an air pump or condenser can rattle.
  • Frequently, warped fan blades and broken motors scrape.
  • A decentered blower wheel may produce a thud.
  • A defective gas valve can produce an excessively loud rumbling.
  • Loose-fitting metal housing fasteners can produce rattling.
  • Compressors or fans with entrapped material can generate clanking sounds.
  • Sheet metal air ducts can pop due to air pressure
  • Frequently, broken air filters, blocked vents, and leaking ductwork hiss.
  • Frequent refrigerant leaks can be heard.

Identifying the source of HVAC sounds might be difficult at times. We are always accessible to help you identify the root cause of a problem and provide prompt

When a heater switches on and off erratically, it may be short cycling. The following are common causes of short cycling:


  • Vents that are unevenly distributed or occluded.
  • A malfunctioning thermostat
  • A clogged air filter that restricts airflow.
  • Condensation switch flaws
  • A corroded flame sensor
  • Inadequate heater maintenance will increase the likelihood of short-cycling problems. Therefore, it is essential to schedule routine maintenance.

Air ducts will gather dust, allergies, pollutants, and microorganisms over time. When you turn on your heater, hazardous particles will be blown throughout your home, creating respiratory issues, allergies, and asthma attacks. The accumulation of dirt, bacteria, pollen, mold spores, insect droppings, and pet dander over time need routine care of ductwork, similar to that of the surfaces in your home.

Dirty Air Filter

The air filter on your heater can greatly enhance air quality by preventing airborne pollutants and impurities from entering your heating system, air ducts, and home. Every one to three months, we recommend replacing your air filter. This will reduce your exposure to irritants and allergies and increase the energy efficiency of your heater.


Upgrade to a higher-quality air filter that may capture tiny particles, resulting in cleaner air. MERV is a grading system for high-quality filters (Minimum Efficiency Reporting Value). Consult with our HVAC consultants to determine which air filters are suitable for your system.

Natural gas, propane, and oil-fueled heaters are susceptible to carbon monoxide (CO) gas leakage. CO is odorless, non-colored, and possibly lethal. Other symptoms of carbon monoxide exposure include shortness of breath, vertigo, headaches, nausea, mental disorientation, vomiting, impaired muscular coordination, damage to the heart and brain, and loss of consciousness.

Installing a carbon monoxide detector as soon as possible is a sensible precaution to consider if you own a combustion heater. A carbon monoxide detector will sound an alarm in the presence of dangerous gases. If this alert sounds, immediately turn off the device, ventilate your home, and contact a professional.

A defective heating system can be expensive to repair. Leaky ducts, soiled filters, broken thermostats, and a host of other flaws can all contribute to high electricity bills. The longer a heater is used, the more likely it is that its efficiency has diminished. Call us if you observe your heater working overtime and your monthly utility bill steadily rising (particularly in the winter). By installing a state-of-the-art unit, a heat pump, or a better chimney exhaust flue, we can save you money over time.

Why Does Your Heater Stop Working Correctly?

There are numerous causes of heater malfunctions. Here are some frequent complications:

  • A dirty fan might result in equipment failure. Inadequate airflow across a heat exchange might cause it to overheat and fail.
  • Contaminated air filters might impede airflow and result in short cycling.
  • A filthy, grimy flame sensor can switch off your heater by failing to detect the flame.
  • Contaminated burners may have difficulty igniting.
  • Wiring and electrical problems can lead to malfunctions.

Frequently Asked Questions

There can be several things that can cause a heater to stop working in Philadelphia. One of the most common culprits is when an onboard thermostat fails, making it impossible for the heater to regulate the temperature in a room correctly.

Damaged electrical wiring could also be responsible, as too little electricity or too much can quickly cause a malfunctioning heater. Low refrigerant levels mean that not enough heat-carrying fluid circulates through the coils, and dirty filters prevent warm air from entering your home, reducing the heating output significantly.

Age also plays a factor – as furnaces get older, components naturally begin to wear down and break while elements can become faulty. In any case, it’s important to have your heating system inspected by an experienced HVAC technician if you notice signs of trouble or if your system has stopped working completely.

If you’re living in Philadelphia, and your heater isn’t working, it’s important to take action right away as temperatures can drop quickly. It’s best to call a trusted local heating specialist who knows the area and the equipment.

He or she will be able to identify the problem, provide a quote and work with you on getting it repaired as quickly as possible. If you’re looking for reliable specialists in the Philadelphia area, consider using an online review system or customer recommendation site to find companies with positive reviews from their customers.

This way, you’ll know that not only is the technician reputable but also knowledgeable about solving your heating issue.

If you live in Philadelphia and think your heater might be broken, there are a few simple ways to confirm. First, if your home isn’t feeling as warm as it typically does during the winter season, that’s one indication something could be wrong.

You can also check for any unusual sounds or smells coming from your unit, as well as checking for soot or debris near the heater vent, which would signal a problem. Finally, you should always check your thermostat to see if it looks like it is functioning correctly. If you discover that your heater is indeed broken, make sure to call a local technician who can provide quality repairs. That way you’ll stay comfortable and safe all winter long!

If your heat is running but not heating, it may be due to several causes. One common cause is a lack of airflow through the registers. Depending on your heating system, you may need filters that need to be replaced periodically or you may have a clogged air duct.


Another potential cause of your heater not functioning properly is a malfunctioning thermostat, in which case replacing the thermostat could be necessary. Finally, it could simply be that you have insufficient heat output from your furnace and would require service from a qualified technician to assess the issue and determine the most suitable repair solution for your system.
