Why Does a Heat Pump Freeze Up: What to Do?

If you have a heat pump installed at your home, you most probably know how environment-friendly, cost-effective, and multi-purpose machinery it is. Not only does it keep you warm during winters, but it can cool your homes too if the temperature goes high.

It is normal to see a thin layer of ice on your heat pump, but things get unusual if more than one layer of ice. That is when you know you need to do some troubleshooting.

But Why Exactly Does a Heat Pump Freeze Up?

This happens because, during winters, the outer coil of the heat pump lowers its temperature below the outside temperature so that it can supply heat. Hence, during the operating cycle, the refrigerant gas condenses and freezes.

Here are a few reasons as to why your heat pump can have a significant freezing issue:-

  • Clogged Filters And Blowers

Small dust and smoke particles can settle down and clog filters and blowers, which leads to insufficient air supply, because of which moisture may freeze on the coil.

  • Faulty Mechanical Component

Any heat pump component can be defective due to excessive use or low maintenance. These components may include-

  • Coils
  • Blades
  • Compressor
  • Condenser
  • Evaporator
  • Broken or leaking valves

  • Low refrigerant levels

With low refrigerant levels, the heat pump loses its ability to cool or heat the system. This may be an installation problem or a case of a system leak.

  • Fan Blades

The fan blades may be blocked due to dirt or particulate deposition, and if the heat pump is operated with still fan blades, it may cause severe damage to the compressor or other essential components of the pump.

  • Malfunctioning Blower

The blower’s job is to circulate air throughout the house, but a blown blower cannot fulfill this requirement. Once found faulty, the blower has to be replaced.

  • Dirty AC Coils

If the coils are dirty, it takes them more time to draw heat from the outside air; this leads to condensation and the pump’s freezing up.

What Should You Do?

  • If you notice a stack of ice on your pump, don’t neglect it. Try to identify the underlying issue.
  • Call a technician. If you cannot identify the problem, better call a technician and resolve your issue. You can contact HVAC contractors, Severna Park, to book technicians for emergencies.
  • Try repairing it yourself if you have ever worked with heat pumps before. But in case you have not, then contact heat pump services, Severna Park.
  • In case of faulty mechanical parts, leaking vents, and corroded coils, contact your retailer for replacement.
  • Prevention is better than cure. You can prepare for such a situation beforehand by calling an HVAC professional and getting your pump checked for any of the above-mentioned technical problems.

If your heat pump is freezing up and you are looking for any heat pump repairing servicesJS Corcoran Heating & Air Conditioning is here to resolve all your issues. You can also contact us at 443-250-9917.

9 Signs That Your Furnace is Dying

With everything going on in the world right now your furnace may be the last thing on your mind. However, it’s critical to keep your furnace in good working order, so you don’t have to worry about it later. But how will you know when something isn’t working?

Here are some obvious indications that your furnace isn’t working properly and needs to be repaired or replaced permanently:

  • The Cost of Heating is Rapidly Rising

It’s possible that the furnace is exhibiting signs of wear and tear and isn’t operating as well as it once did. A blocked filter makes a furnace work harder to draw air through it. Therefore cleaning filters regularly will minimize furnace run time and make it more cost-effective. Try the furnace repair, Severna Park.

  • Changes in Pilot Flame Color

The pilot light should be a deep blue color when your furnace works properly. If your furnace’s pilot light turns yellow, it signifies there isn’t enough air in the system, resulting in incomplete combustion. So be cautious and take all necessary precautions if the pilot flame changes shape or color.

  • Strange Noises

If your furnace starts making screeching noises, especially metal scraping metal, something is probably loose and needs to be fixed right once. Ignoring these sounds may result in more costly repairs in the future.

  • Dry or Dusty Air

If you notice more dust, dander, soot, rust, or filth accumulating in your home while your furnace is running, it’s time to replace or repair your system. Your furnace could be to blame if you’ve noticed your home’s air is arid.

  • Increased Health-Related Issues

Furnaces emit a lot of carbon monoxide, which is dangerous to your health. One of the most common sources of this hazardous gas is your furnace. While a well-tuned furnace will not cause this issue, a faulty furnace may.

  • Soot

When you use your furnace to generate heat, it burns fuel, particularly natural gas, and there are residues left over when the process is completed. Carbon, the principal element in black soot, is one of the combustion byproducts sent up the heat exchanger and out of the house. One of the symptoms that your furnace is failing is the presence of soot.

  • High Furnace Age

Do you believe your furnace will last indefinitely? If your furnace is more than 15 years old, you should consider furnace replacement choices. The problem with heating systems surviving longer is that their efficiency is often reduced after 20 years, even if they still operate.

  • Inconsistent Heating

Do you notice hot and cold patches as you move through your house? Your furnace is most likely the source of the problem. As your furnace gets older, it may become more difficult to distribute heat uniformly throughout your home, resulting in a more uncomfortable environment and higher energy bills, so search for a furnace check-up near me.

When any of the following indicators appear, respond quickly and take the necessary safeguards before it’s too late. JS Corcoran Heating & Air Conditioning is here to help you. Feel free to contact us at (443) 250-9917.

Important Benefits Of Furnace Cleaning

It’s important to keep up with furnace cleaning during the heating season if you want to keep your home warm. The parts inside your blower compartment are vulnerable to dust and dirt, which can weaken the entire system and cause safety issues.

At the very least, knowing how to change the system’s air filter will go a long way towards keeping it clean. When it’s frequently running, check it once a month. Replace it with a filter that’s right for your system and the exact size the manufacturer recommends, so you don’t have to clean your furnace as often between expert maintenance appointments.

Based on your skill level and comfort with mechanical systems, you might be able to clean parts of the furnace components yourself before and throughout the heating season. If you’re not comfortable working around the furnace or can’t get to its key sections, Corcoran Heating and Air will assist you with a full system cleaning and tune-up. Book an appointment with us for an HVAC tune-up in Severna Park today.

This blog will go over all of the advantages of having a furnace cleaned so that you can be warm and worry-free this winter.

  • Lower Utility Bills

You’re probably aware that clogged ducting reduces HVAC efficiency and increases utility bills. Clean ductwork, on the other hand, can reduce utility bills and maximize efficiency. That’s why it’s critical to have your home’s ducts cleaned every two years. If you keep up with a regular air duct cleaning plan, your ducts will remain free of hazardous particles that might bog down your system.

  • Increased Security

Safety is always the top priority when it comes to your family and home. Cleaning and adjusting the burner assembly, cleaning the ignition assembly, cleaning or changing air filters, inspecting the heat exchanger, and testing safety controls are all important to ensure security. You can heat your home without worrying about any safety hazards if you conduct a thorough inspection and cleaning.

  • Improved efficiency

The furnace needs to work harder when dirt covers the blower motor, switches, heat exchanger, and ignition system. A clogged filter would limit the amount of air passing through the heat exchanger, causing your furnace to run in longer cycles. Since dirt insulates the heat exchanger, a vital and expensive component of furnaces, the air blowing over won’t absorb as much heat, extending the time it operates.

  • Extended lifespan

Although furnaces are designed to produce heat, unclean parts such as the blower motor and fan, electrical switches and controls, and the heat exchanger accelerate the aging process.

  • Repairs Are Less Frequent

Cleaning, lubrication, and inspection of your furnace ensure that it operates at full efficiency, resulting in fewer malfunctions or difficulties. Because of this, your furnace will need lesser repairs.

What Are The Consequences Of Not Maintaining Your HVAC System?

A good HVAC maintenance plan can keep your equipment functioning smoothly, require fewer furnace repairs in Severna Park, increase its reliability, and extend its life. When you don’t have a maintenance plan, the following things can happen:

Blocked Condenser

One of the most important components of your HVAC system is the condenser. It’s in charge of de superheating, condensing, and sub cooling to ensure that the air in your home is at the proper temperature. When a condenser is clogged, the heat transfer that normally occurs is prevented, and the temperature of the condenser rises. Your HVAC system will run inefficiently when this happens, and your condenser may burn out if not addressed.

Leaks

Several frequent circumstances like the drain hole being clogged or blocked, the condenser pump malfunctioning, the seals on your unit aren’t tight, or your hose being clogged or blocked might cause leaks in an HVAC unit.

Power Malfunctions

A proper furnace maintenance plan will help you ensure that your HVAC equipment can power up and power down properly. If it can’t, you’ll be frustrated when your home is excessively hot or cold, and you can’t set the thermostat because your unit isn’t running properly.

Dirty Blower

Your HVAC system’s blower is in charge of circulating warm or cool air throughout your home. A blower will fail if it gets dirty enough, and once it fails, it’s an indication that additional issues are on the way. Many HVAC professionals will urge you to replace your complete HVAC system if this happens.

Improperly Functioning Thermostat

Your HVAC unit may not turn on or off when it’s meant to if your thermostat isn’t working properly. This is not only bad for the unit, but it is also detrimental to you and your family’s comfort.

Dirty Coils

The evaporator coil on your interior HVAC unit functions similarly to a radiator to ensure that the air moving through your duct is suitably heated or cooled. A filthy evaporator coil can limit airflow, lowering the efficiency of your unit significantly. Mold and mildew can grow in the dirt, causing poor indoor air quality.

The condenser coil on your exterior HVAC unit is responsible for removing the hot air supplied to it during the summer. The more clean the coil is, the better it can manage the hot air. If your condenser coil is unclean, your unit’s efficiency may suffer, resulting in higher energy bills and a shorter lifespan.

Dirty Filter

A properly cleaned air filter will provide you with high-quality indoor air that will not only prevent illness but will also minimize its duration. When your air filter is dirty, airborne particles aren’t screened; instead, they enter your home through your ductwork and are inhaled by you and your family.

If you’re looking for a furnace check-up near me, you’re at the right place! At Corcoran Heating and Air, we’re always telling our customers how important HVAC maintenance is. Book your furnace repair in Severna Park with us and get your HVAC maintenance plan from our expert HVAC technicians.

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

If the situation persists, you may have to look for a furnace check-up near me. J.S. Corcoran Heating and Air conditioning specialize in all kinds of furnace services such as repair, maintenance, and installation. Call today at (443)-250-9917 and get quality service for your Goodman furnace.

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.

Solution

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.

Solution

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.

Solution

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.

Solution

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.

Solution

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.

If your filter is doing fine, look for the main AC unit itself. Clean the surroundings of your air conditioning unit. Remove all the leaves, sticks, dirt, or debris. Do keep in mind that debris can damage your system. Clean all of it to keep your air conditioner healthy.

Weird noise is also a sign of a problem. Strange and loud sounds simply mean you have to contact your air conditioner contractor in Severna Park right away to get rid of the sounds and repair your AC.

If your air conditioner is switching on and off frequently, it means you have to hire an HVAC contractor to make sure that your air conditioner runs correctly. Turning on and off means your air conditioner unit is insufficient and needs proper care. You have to keep your air conditioner maintained to avoid such problems.

If the unit is shutting off, check your fuse box for a blown a fuse. If it busted, you have to contact your HVAC contractor. If the climate is the reason for the blown fuse, it’s understandable, but if not, then you have to take care of this situation carefully and immediately.

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.

Summer is the season when everybody is relying on an air conditioner. If you have any questions regarding your AC unit, size, or anything for that matter, You should contact your HVAC contractor and schedule a meeting.
