Interpreting Solid Red Light On Furnace

If your oil furnace is not turning on, you could notice a solid red light on the burner unit. hen this red light, also known as a lockout light, glows, it means that a safety system on your furnace has forced a close down due to finding a problem or recognizing a malfunction.

Reasons For Solid Red Light Appearing

The lack of a flame when the burner is on is the most typical cause of a furnace shutdown, but there are numerous additional possibilities, or it could merely be a fluke. If your furnace has a visual display that shows a fault code, you may quickly examine the fault code to determine the cause of the issue. Look into the furnace manual to understand the meaning of the fault code.

If you do not have a digital display, there are a few things you should look into before pressing the reset button or calling for repair –

  • If There is Oil in The Tank

If no oil reaches the furnace, it will not fire, resulting in furnace suspension. Check the oil gauge to ensure you have enough oil, and if you don’t, call for delivery. Consider signing up for automatic delivery to avoid this from occurring anymore. You won’t be worrying about forgetting to fill your tank this way.

  • Check if The Oil Valve is Open

A shut oil valve stops oil from reaching the burner and thus hinders it from firing. The furnace will close down if no flame is detected. Open the valve if it’s closed.

  • Press The Reset Button

Usually, the reset button and the red light are the same buttons, although this is not always the case. If they aren’t, the reset button is generally nearby. Press and release the reset button to check if the furnace will ignite.

If it does, and it only happened once, it was most likely a fluke. However, if your oil furnace continues to shut off, DO NOT REPEATEDLY PRESS THE RESET BUTTON. Contact a professional HVAC contractor immediately because this is a symptom of a more grave condition.

  • Regular Furnace Maintenance

The automated shutdown of your furnace is a security measure devised to protect you and your furnace from further harm caused by the problem that made it close down in the first place. Many of the reasons for a breakdown, such as a clogged filter or a malfunctioning fuel pump, can be prevented if your oil furnace is tuned up once a year. Your HVAC tune-up contractor will ensure that all parts are clean and working correctly, providing you with a sense of safety during the heating season.

How Do You Reset A Goodman Furnace?

We often hear a renowned brand name when it comes to household furnaces, yes – it’s the Goodman Furnaces. With exceptional quality and affordability, Goodman furnaces are leading the home heating industry. Moreover, it also offers premier warranties such as replacing the entire furnace as the case may be. Ensuring a smooth operation, Goodman furnaces have safety measures such as primary limit switch, rollout limit switch, and lockout mode.
Some of these safety features reset automatically while some require manual operation. No one wants to shiver in the biting cold as the furnace stops working. Hence, we hastily tend to call for a furnace repair in Severna Park. Well, the good news is, it is a matter of a few minutes to reset your Goodman furnace.

Primary Limit Switch

Located on the partition panel, the primary limit switch will monitor the temperature of the heat exchanger. The limit switch will kick into action when the system detects overheating of the furnace. However, the primary limit switch is programmed to reset on its own. In case it doesn’t do so, you can always search for a furnace check-up near me and get the necessary help.

Rollout limit switch

This safety switch monitors the burner flame and is located on the burner assembly. When the flame is not properly drawn into the heat exchanger, the rollout limit switch gets activated. Unlike the primary limit switch, this has to be reset manually for the furnace to resume operations. Here is how you can reset the Goodman furnace rollout limit switch:
Step 1
Before performing any resets, always ensure that the furnace is not receiving any electrical supply. For this, flip the circuit breaker switch to the ‘off’ position and proceed further.

Step 2
Remove the access panel of the furnace so that you can access the internal components. This can either be done by lifting the panel sides or by removing screws from the panel. This differs as per different models of the Goodman furnace.

Step 3
Inside the burner assembly, look for the rollout limit switch. Hold the red reset button for a few seconds and release it. Turn on the circuit breaker switch and check if the problem has been solved. Otherwise, you may need to call a furnace repair in Severna Park.

Resetting The Lockout Mode

If unable to ignite within 3 attempts for a single heat call, the Goodman furnace goes into a lockout mode. Unless reset manually, the furnace will not attempt to run again. The furnace will reset by:

  • Automatic reset by the integrated module after 1 hour of lockout
  • Cut off the power supply for 30 seconds or more
  • Lower thermostat for a brief period and return to previous settings

5 Most Common AC Problems And Their Solutions

Air conditioning problems are common, but few people have the specific knowledge to figure out why.

With regular servicing, any potential problems can be detected early, saving you the expense of a later repair.

These Are The Most Common Issues And Their Solutions :

1. Filter problems

A clogged filter can reduce airflow, reducing the unit’s ability to chill air effectively and efficiently.

Some filters need to be changed monthly, while others need to change three times per year.


Your air filter should be thoroughly cleaned by rinsing it in warm water after removing the dirt.

If the problem continues, invest in a new filter for your system.

2. Sensor issues

ACs have a thermostat sensor that measures the temperature coming from the evaporator coil.

A malfunctioning thermostat could result in a rapid increase in the temperature of your home, increasing your energy bill.

Unstable sensors, on the other hand, can cause the machine to cycle and behave abnormally.


Replacement is required if the problem persists. Instead of buying a new thermostat, it’s better to invest in a smart one.

It will make it easier to program your AC and help you save a lot of money by avoiding unnecessary expenditures.

3. Refrigerant leakage

Corrosion of the indoor coil, factory defects in the unit, and improper installation can all lead to refrigerant leaks.

AC with low refrigerants cannot produce much cool air. Besides, adding more refrigerant to a leaking AC also cannot fix the problem.


Early detection can help you save thousands of dollars in repairs or replacements of your system and keep your home cool.

If there are any leaks in the system, a technician should fix them. Your refrigerant coil should be replaced if there are several serious leaks.

4. Fuse or breaker problems

Alternating fuses in the fuse box is not only inconvenient, but it can also be a sign of a more significant problem with your cooling system.

A problem with the electrical system, the power source, or the circuit that supplies your AC is most likely to cause it to trip a breaker.


Breakers and fuses are designed to trip or blow when too much power is transmitted through a line, and it would be risky to try and fix it at home.

It’s essential to hire professionals like AC contractors Severna Park for electrical issues with your HVAC system.

5. Compressor malfunction

Electrical problems caused due to cracks and holes in the suction lines of your air conditioning system can permanently damage the compressor and other components of your AC

If your system has too much or too little oil lubricant, it will not function properly, making way for contaminants such as moisture and bird droppings to enter the air conditioning system.


To keep your AC compressor safe, you must have it regularly serviced by a licensed HVAC professional.

If you are looking for an AC service near me in Severna Park to save money on AC repair, we can help. You can call us at 443-250-9917.

7 Things You Need To Know About Managing Your Air Conditioning

Managing your air conditioning has a very different set of priorities than the responsibilities associated with home care, like cooking and furnace maintenance.

Your home air conditioner keeps the home cool by blowing cool air into your home and removing the heat out of that air. The air conditioner is solely dependent on the efficiency of system units.

If your air conditioner fails to cool the room and you experience humidity and constant temperature change, it’s time to hire a professional to check the issue.

Note These Seven Tips Before Things Get Even More Crowded:

  • Air Conditioner Filters:

One of the crucial components of an air conditioner is air filters. They maintain the indoor air quality by trapping dust and dirt particles from the air onto the filter.

The timely cleaning of air filters prevents clogging with particles that affect indoor air quality. Dirty filters obstruct airflow and decrease a system’s performance significantly.

While if you clean the air filter regularly, an AC will consume approximately 5-15% less energy to cool the room.

  • AC Coils:

There are two coils in an air conditioner: evaporator coil and condenser coil. The air filter prevents the evaporator filter from dust particles.

Even though you clean the air filter, the evaporator coil will still attract some dirt during the cooling process. Eventually, the evaporator coil’s efficiency is reduced and is not able to absorb heat.

To avoid this situation, make sure to clean the evaporator coils annually.

If the outdoor environment is dusty, you will notice dirt on the outdoor condenser coil very often. Maintain the area around the condenser coil by removing debris and trimming foliage for sufficient airflow.

  • Condensate drains:

It’s essential to clean the drain line to prevent the clogging of water into the pan. You can maintain the drain line by passing a stiff wire through the drain channels.

You can also pour a dash of vinegar to clean the drain line. If you are not aware of the cleaning of drain channels, hire a professional to help you resolve the clogged condensate drain.

Connect with our team today for any HVAC issues if you are still looking for ac service near me.

  • Coil Fins:

The evaporator and condenser coils get bent easily, which blocks airflow through the coil fins. A tool called “fin comb” helps fins retain their original state and maintains efficiency.

  • Window Seals:

During the start of winter, check the seal between the air conditioner and the window frame. It must be in contact with the unit’s metal case.

Excess moisture can damage this seal, allowing cool air to leave your house.

  • A final touch for winters:

During winters, homeowners usually forget about the air conditioners. It is essential to cover the air conditioner or, you can remove and store it.

It protects the unit from snowy weather and the accumulation of debris.

Also, check your thermostat. It’s a remote that gives you the power to control your air conditioning unit. Reduce the temperature to check if the AC unit is working correctly. If not, then there is an issue with your motor or compressor.

4 Signs It’s Time To Replace Your AC Unit

One of the most challenging decisions you’ll have to make as a homeowner regarding your air conditioner is deciding when to replace your old system with a new unit. Although purchasing a new air conditioner is an expensive investment, so are the costs of maintaining and operating an outdated, inadequate unit.

Air conditioners, like old cars, show signs of wear and tear before they fail. By observing the condition of your older air conditioner, you can begin planning for the purchase of a new unit even before you need it. Only qualified HVAC technicians can tell whether a broken air conditioner requires new thermostat batteries or a more substantial repair.

If you require a new air conditioning system or maintenance service for the existing one from a reliable HVAC company, you can look for a technician by Googling “AC service near me.”

Signs That Your Air Conditioner Needs Replacement

Modern air conditioners can last up to 15 years, so you must select the appropriate unit for your home’s cooling needs. However, if your older air conditioner breaks down on a 100-degree day, you may not have much choice. Here are some signs that will help you know your AC system needs a replacement:

  • Air Conditioner Unit Older Than 10-Years

A well-maintained air conditioner should last between 10 and 12 years. However, if you require costly repairs and your air conditioner is more than 10-years old, replacing it may be a more cost-effective option. It is especially true when you consider the progressions in air conditioner system efficiency over the last decade.

  • Frequent Breakdowns

Several prevalent air conditioner problems arise due to a lack of maintenance, and having your unit serviced will help deter them. However, recurrent breakdowns necessitate regular repairs, and the cost of those repairs can quickly mount.

At some point, it may be more cost-effective to buy a new unit rather than invest in costly repairs, especially if your warranty has expired. If you want professional assistance for the issues regarding your AC system, look for an AC replacement in Severna Park, MD.

  • Surged Electricity Bills

Increased energy bills may imply that your air conditioner is not functioning correctly or is losing efficiency. Electricity bills commonly begin to rise as an air conditioner ages, so the two aspects may be related.

Receiving a large energy bill once or twice is not cause for concern. However, if your energy bills keep rising, you may need to start looking for a new air conditioner.

  • Utilization Of R-22 Freon In The System

R-22 Freon or HCFC-22 is an expensive refrigerant that you can use for your AC system, especially if it is more than 10-years old.

Choosing A Good HVAC Contractor: A Beginner’s Guide

It might be difficult to choose the correct heating, ventilation, and air conditioning (HVAC) provider when seeking air conditioner contractors in Severna Park. Everyone wants to work with a contractor they can depend on. Has your air conditioning system been working for ten years? That implies you may have to replace it in the coming years.

As a result, we have compiled a list of pointers to assist you in selecting the best HVAC air conditioner contractors in Severna Park for your needs. Here are five things to think about while you look for a new job.

Expertise and Licensing

  • Your HVAC system is likely the most expensive piece of equipment in your house, so you have to be sure that whoever works on it has received the necessary training. Contractors in the HVAC business must be properly licensed; to receive a license, a contractor must have five years of experience in the sector before applying. A firm should be able to carry a minimum amount of bonding and insurance in addition to the license. Homeowners’ insurance protects them in the event of an accident or injury.

Inspection of The House

  • If you need an HVAC system installed, possible contractors should do a full house assessment to find the best heating and cooling option. The square footage of the house, the R-value of the insulation, and the number of windows, and which direction they face are all factors to consider. Leaks, loose parts, and insulation should all be checked by contractors. Accordingly, the inspector will suggest you the right AC replacement in Severna Park.

Letters of Recommendation

  • Request and follow up on references and recommendations. Inquire about whether works were finished on schedule and budget. Inquire about the company’s cleanliness and respect for the property of the homeowner. A professional HVAC expert will also be proud of his or her firm, with well-maintained trucks and the business name prominently displayed like air conditioner contractors in Severna Park.

Discounts and Promotions

  • As an HVAC system is an important investment, look for rebates on energy-efficient equipment or inquire about offers with your dealer. Installing energy-efficient equipment might earn you a refund from utility providers.

What Happens If Ac Is Not Serviced?

In these times of hot temperatures, it is essential to keep your air conditioning system sorted out beforehand, so you are not uncomfortable in the heat.

Many times, when your air conditioner breaks down, you are perplexed about the reason. It happens when you fail to maintain your air conditioner regularly or often. Ac’s are an essential asset in every urban household nowadays, yet most homeowners fail to maintain their health. It is generally advisable to schedule regular appointments for AC services near them to ensure prompt maintenance.

If  You Do Not Have Your Air Conditioner Serviced And Maintained Regularly, the Following Scenarios May Occur:

  • Polluted in-House Airflow

Ac’s are prone to accumulate dirt, dust, pollen, and other particles in the environment over time, which can significantly impact the quality of airflow in the home. It can also cause dangerous infections such as legionnaire’s disease, which is frequently spread when contaminated water droplets are dispersed throughout the air conditioning system. Bad air quality can affect the health of the residents and can increase hospital bills. For routine maintenance, always contact AC service near you for rapid service.

  • Increase Utility Bill

When air conditioners are not serviced for a long period, their parts begin to wear out. They begin to consume more energy, which may lead to an increase in monthly costs. You must understand that air conditioners are devices that will degrade over time. If servicing is neglected for a long time, an AC can break down, which will only increase the cost of maintenance. It must be serviced regularly to perform properly.

  • Low Cooling Effect

If air conditioners are not serviced regularly, the refrigerants installed in them may suffer. Ac’s are unable to chill the space even when the temperature is kept low. Defects in the chilling effect can be caused by a variety of factors, including coolant leakage or a low refrigerant level. To avoid low cooling effects, it is usually advisable to seek Ac services near you.

  • Costly Replacement Parts

If you discover a problem with their air conditioners, you must contact an Ac service near you as soon as possible to avoid delays. If your air conditioner is not serviced regularly, original parts may be damaged, causing a costly replacement. Loss of original parts can result not only in increased expenses but many times it may become impossible to find a new original replacement.
