Is the AC Compressor Repairable?

1. What is an AC Compressor?

An air conditioning compressor is a significant element of an air cooling cycle. It is a device that converts power into energy while removing present heat from the air and thereby circulating the newly produced energy around in the atmosphere. In simple words, it is nothing but a machine that changes the climate from hot to cold in a closed space, making summer seem like winter. 

However, there are various types of AC compressors available in today’s market, namely :

  • Reciprocating air conditioning compressor
  • Scroll air conditioning compressor
  • Screw the air conditioning compressor
  • Rotary air conditioning compressor
  • Centrifugal air conditioning compressor

2. How Does an AC Compressor Function?

The compressor plays a very effective role in the cycle. The process begins by pulling the heat out of the air present in the space, cooling it through an evaporator called coils and releasing the transformed cool air into the surrounding. There is a liquid known as a refrigerant that absorbs heat and converts it into a form of gas. The gas again becomes liquid transported out of the condenser. The compressor then ensures the movement of the refrigerant between the evaporator and condenser. So, if there is no air conditioning compressor, expect no cooling effect, as simple as that. 

3. What Can Cause Damage to an AC Compressor?

There is more than one reason for a possible occurrence of an air conditioner failure, and they vary widely from each other. The most common causes are the ones listed below: 

1. Electrical error
2. Excess refrigerant
3. Suction line blockage
4. Insufficient cooling
5. Overheating
6. Refrigerant leaks
7. Age

Another major factor that causes this failure is trying to solve the problem by oneself or contacting an ineligible person to save bucks temporarily. This worsens the condition, so try to be mindful of the current decision keeping future outcomes in mind. 

4. Is it Possible to Get an AC Compressor Repaired?

A damaged air conditioner compressor is undoubtedly a technical issue that may be complex and expensive. However, it surely is repairable provided it is detected and corrected by a certified HVAC professional as early as possible. The easiest way to prevent such mishaps is to expose them to routine maintenance regularly. Commit to a continuous routine follow-up to ensure no future failure of the air conditioner compressor, saving unnecessary expenditure on buying a new one.

How to Remove Foul Smell From Your Air Conditioner

A well-functioning air conditioner should neither create a racket nor emit a smell. If you experience any air conditioner smells, it is clear that something is not right. A smell could signal minor damage or a more serious one that needs to be addressed immediately. 

Let’s look at some of the familiar smells you may get from your AC and how to get rid of them. 


Accumulation of dust on the filters can become mold due to moisture. Mold can also clog up your condensate drain line and cause your air conditioner to smell musty.

How to Clean

  1. Use a soft brush to dust the insides of the unit.
  2. Clean the vent and duct with a mild cleaning solution.
  3. Wipe out all the water from the unit.
  4. Let it dry for a couple of hours before use.

Dead Animals

When your AC is not in use for a long time, rodents or reptiles may get into it and eventually die inside it. Dead animals can be the cause of a stench in your AC.

How to Clean:

  1. Remove the outcast and wear latex gloves to remove the dead animal.
  2. Spray a foaming coil cleaner on the air conditioner’s coil.
  3. Leave it for 10-15 minutes to loosen any dirt.
  4. Rinse the coil until all the dirt is removed.
  5. Let the coil dry completely before replacing the outer case.

Cigarette Smoke

If you regularly smoke indoors with your AC on, your AC will eventually smell stale cigarettes when turned on.

How to Eliminate: 

  1. Change your AC filters every 60 days.
  2. Smoking outdoors is a better way to deal with this smell.


If there is a block or rupture in your sewer vent pipe, this could cause your AC to smell like raw sewage and could be hazardous to your health.

How to Eliminate:

  1. Call in a plumber to repair your drainage system.
  2. If the smell persists, contact an HVAC technician immediately.

Rotten Eggs

If your AC smells of rotten eggs or sulfur, there could be a gas leak gas making its way into your ventilation. This is a serious problem.

How to Handle:

  1. Turn off your gas supply immediately.
  2. Open all windows and doors to let out the gas.
  3. Contact your gas company immediately to rectify the problem. 

Oil or Burning Plastic

An oily smell indicates an oil leak or malfunctioning of your unit’s oil burner. A burnt smell could mean that some component of your AC is overheating.

How to Remove 

In both scenarios, it’s best to call an expert in HVAC services to check your AC unit thoroughly. Regular maintenance of your AC will take care of such problems. 


While attending to minor issues with your air conditioner by yourself may seem convenient, we would not recommend it unless you have prior experience.

What AC Maintenance Programs Can Do For You?

JS Corcoran Heating & Air Conditioning in Maryland provides you with the best and most reliable air conditioning services. As we move forward, here are some reasons for what an AC maintenance program can do for you.

Energy Conservation

As the age of your AC increases, the performance decreases over the years. A poorly-functioning AC pulls in a lot of electrical energy and causes a high cost of electricity. AC maintenance takes place at a scheduled interval and hence enhances the regularity of the service. If you want to save money and avoid future repairs, it is the right time for you to sign in for an AC maintenance program.

Better Air Quality

Your air conditioner is responsible for more than just cooling the air. A healthy HVAC system ensures better air quality indoors and provides comfort on summer days. A maintenance program can regulate the AC services and ensure the AC is not dirty.

AC services like tune-ups involve cleaning the filters and the condenser coils to ensure no air is stuck inside. Dirty filters can spread pollutants and toxins in the air that cause illness and discomfort.

Fewer Repairs and Long Lifespan

As the age of your HVAC system increases, the wear and tear also becomes frequent. It results in repair work from time to time. But if your AC unit is maintained regularly, such wear and tears decrease. You will also be able to save a lot of money by doing this and prolonging the life of your air conditioner. If you are looking for an AC servicing nearby, call us for better guidance from the experts.

Increased Resale Value

When your HVAC unit becomes more than a decade old, you might want it replaced. But what if the resale value of your AC is extremely minimal? To guarantee this doesn’t happen, you must get regular maintenance for your AC. AC maintenance program includes regular servicing so that the performance of your AC is maintained and stable throughout the years.

Avoiding Risks

Since your HVAC unit has been in use for many years, it is possible for some malfunctioning parts. There can be leakages and broken parts in your AC that need to be addressed. When you get regular maintenance, a professional technician can help you learn more about the faulty parts.

Holes in the condenser can leak the refrigerant out of the AC and go to the electric pole. It can be dangerous as the refrigerant has strong chemicals that can harm your health. Thus book an appointment for a maintenance program.

Maintain Your Warranty Period

If your HVAC unit is still under the warranty period, signing up for a maintenance program will work best for you. It is better to get regular services for your AC before the warranty period finishes. All the services are free of cost during the warranty period, and hence you should make most of it!

5 Ways Most AC Companies Cut Corners On Installation

Summers are comfortable when you are with family and friends at home with your air conditioning unit on. Many people consider installing an AC if they don’t have one already. However, you want to ensure that your HVAC technician does not miss important things during installation.

An unprofessional installation can lead to various problems in the future, such as increased utility bills, reduced airflow, and frequent repairs. It is important to contact professionals regarding AC installation and AC service near me.

Five Shortcuts Most AC Companies Apply:

  1. The Ductwork for Each Room is Not Properly Sized

    When installing new ductwork, remind your AC installer to calculate the air volume needed for each room. Also, there are instances when the company doesn’t know how to calculate it. Instead, they will replace the old one with the new one of the same size.

    An experienced technician will precisely calculate and provide you with the proper size ductwork. Thus, ensuring the efficiency and longevity of your AC unit.

  2. Safety Systems Not Installed

    Companies often fail to install a safety system that helps you protect from blockage of backed water. A little water dripping from the condensate system is normal, but a significant amount is a sign of concern.

  3. A System With The Too-Small Air Return

    Another big shortcut most companies take is not calculating how big your system’s Air Return needs are. A correctly sized air return maintains adequate airflow throughout your home. An expert in AC installation calculates exact measurements to meet your house’s needs.

  4. Not Replacing the ‘Line Set’

    A line set is referred to as the refrigerant pipes or freon pipes. These lines often run in places that are difficult to access, making them a challenge to replace. So, most companies do not replace them. They know that most homeowners won’t even notice they weren’t replaced.

  5. Failing to Install Plenum Sheet Metal Transitions for Ductwork

    The plenum is a box through which cooled air is pushed into the ductwork. If you are connecting a new plenum to existing ductwork, the transition from the plenum to the ductwork must be created with sheet metal, and this must be done by the professionals, to avoid any mishaps.

    The problem is that many companies have technicians who don’t know exactly what they are doing when working with sheet metal. If the fabricating is not done precisely, too much of your cooled air will escape before entering your home.

    AC installation is cumbersome work. At JS Corcoran Heating & Air, we understand that you trust us with your home and cooling unit, and it is a matter we do not take lightly. Our HVAC professionals are skilled, trained, competent, and experienced in dealing with HVAC brands.

    We aim to provide our customers 100% satisfaction and work 24 hours to fulfill your demands. Do not risk paying for a brand new ac unit only to get stuck with your old one. Contact us today for air conditioner contractors in Severna Park.

What Are The 10 Most Common Furnace Problems

Surviving the freezing winter season in Severna Park is intolerable without an effective heating system to cool down your home. So, if your furnace unit is demanding frequent repairs, it is better to call experts for an HVAC tune-up in Severna Park to avoid any significant breakdowns.

Some Common Furnace Issues That Many Homeowners Face

Below are some of the most prevalent issues your furnace might face over time.

  • Dirty or Clogged Air Filters

A clogged or dirty air filter is a prevalent cause of furnace breakdown. So to avoid this issue, it is prudent to get the air filters changed every three months or as per the manufacturer’s instructions.

  • Thermostat Issues

One easy solution is to ensure that your furnace thermostat (which controls the temperature in your house) remains turned on and that the inside is clean and set to the right temperature. If the problem persists, it could indicate something more severe.

  • Refrigerant Leaks

When the furnace’s refrigerant leaks, the machine will stop working adequately, causing temperature changes. Since the degree of the leak affects the cost of repair, it is better to have it inspected out once a year by competent HVAC contractors in Severna Park.

  • Drainage

Like the furnace air filters, usually, the drain line also gets clogged with trash, dust, and lint. The drain pan will fill up if it becomes obstructed, and water will pour out, potentially causing damage to the heating system or whatever remains situated near the pan.

  • Breakers or Fuses

One of the initial points a heating and cooling expert looks for when a furnace breaks down is the breaker. Breakers and fuses guard the compressor or the engine of your furnace from overheating.

  • Capacitors

The engines that drive the compressor and furnace fans won’t operate without capacitors. The beginning capacitor sends a single jolt to initiate the motor, while the run capacitor transmits a series of jolts to keep it running. So if any one of these elements burns out, the furnace unit will not function properly.

  • Compressor

The compressor applies power to the refrigerant for better heat exchange and drives it through the coils. So when the compressor fails, the furnace will not heat your home.

  • Evaporator Coils

With a series of air ducts, evaporator coils gather cold air and return it to the house as warm air. However, when these coils break down, your furnace will malfunction.

  • Condenser Coils

As the compressor and condenser coils remain situated outside, they can become dirty due to the weather. So it is better to clean them regularly with a hose or call experts for routine servicing.

  • Worn Contractor

The blower motor, compressor, and condenser fan motor have contactors in a furnace. They join the compressor and motors to an electrical source, which switches them on. When the contactor turns and pits, it becomes challenging for the electric current to trigger the engines.

How To Fix Your Heater Like A Pro

When you own a heating system, it is good to have some basic knowledge about its working. Like many others in this time DIY projects have become very popular. Hence, if you want to troubleshoot your heater, we have got you covered.

Here is a list of a few steps you can take to help you solve the general heater problems without needing professional assistance. But if, even after following the given steps, the problem with your heater continues, then be sure to contact furnace inspection, Severna Park.

Check If the Thermostat is Working

Well, it may sound like an extremely basic thing, but in many cases, the thermostat is the reason why your heater is not working. If a battery powers your thermostat, it is possible that the reason behind your thermostat not responding; is a dead battery. You can replace the old battery with a new one, and your problem will be solved.

Check Your Thermostat Settings

Your heater may not be working because someone might have accidentally changed the thermostat settings, or a glitch in the thermostat might have reset it. So, it is better to look at your thermostat settings and make sure it has been set to HEAT before picking up the phone and calling a professional.

Change The Filter

A dirty air filter is the root cause of many problems with HVAC systems. And thus, you need to change or clean it regularly. When dust and dirt have clogged the filters, your furnace becomes less efficient, and the heat exchanger shuts off quickly and overheats. However, it is not a difficult task to change the air filters. You can easily do it yourself. Your owner’s manual is also there to guide you in any confusion.

Check The Gas Valve

If you have a gas-powered furnace and your heater is not working, first, check the gas valve. And if you find the lever perpendicular to the gas pipe, it means that the valve is closed. And to open the gas valve, you will need to turn the lever and it parallel to the gas pipe. It will allow the gas to flow into the furnace.

Check The Circuit Breakers

Whether you have a gas-based heating system or an oil-based heating system, it will need electricity for operating. So if your heater is not working, check the circuit breaker panel of your home and check for any tripped circuit breakers, and if you find one, reset it.

Check The Exhaust Vents

The leaves or debris may have blocked your intake or exhaust vents, or if you live in heavy snowfall areas, ice may have clogged your pipes. Then removing and clearing all the leaves, debris and snow might help your heater retain its initial heating ability.

Why Your Furnace Is Not Lighting Up?

The ‘click’ sound that a furnace makes when it switches on is satisfying for furnace owners. But all the satisfaction goes down the drain when your furnace does not generate heat, and the house remains dead cold. Now, what can you do?

A malfunctioning furnace is extremely common. You can contact any of the leading HVAC contractors in Severna Park to fix your furnace. If you want to check your furnace yourself, here are some troubleshooting tips that you can checklist before contacting a professional for help:


Your thermostat decides what the house temperature should be. It instructs the furnace of the right temperature, and the house warms. However, if your thermostat does not detect the desired temperature, your home will either remain cold or become scorching hot.

Both situations are problematic for you. There are two solutions to this issue. First, check your current thermostat regularly for its batteries and wirings, and contact your technician accordingly. Second, if you do not have the time to give your current thermostat, install a smart thermostat that will understand your temperature requirements after a few days and control the furnace accordingly.


The breaker supplies the main power to the furnace. Sometimes, the breaker trips due to voltage differences. The tripping of the breaker protects the furnace from damage due to excessive current flow.

Go to the circuit and check the breaker. If it has tripped, you will have to replace it with a new one. Ensure to buy the right size breaker or ask your technician for furnace repair in Severna Park.


Check the furnace switch if the breaker is functioning well, yet the furnace does not light up. The switch should be near the furnace and easy to locate. Ensure that the switch has no breaks or tears on it.

Air filters

Air filters are an extremely important part of the furnace. Filters ensure that the indoor air is free from allergens, bacteria, viruses, dirt, dust, and pet hair. Moreover, air filters create a smooth airflow path from the system to the house and vice versa.

If the air filters are dirty and clogged, the indoor air quality will significantly fall. Also, the system will have to work harder to push the air into the home due to blocked paths. If you do not clean your air filters regularly, they may force the system to break down due to excessive working.

Flame Sensor

As the name suggests, the flame sensor senses the flame and helps in lighting up the furnace. If the flame sensor is faulty or dirty, it will not function properly and cause the whole system to suffer. All you need to do is clean the flame sensor and put it back in its place.

These troubleshooting tips should be enough to help you fix your furnace. But if the problem persists, you should contact an HVAC company for a furnace check-up near me. J. S. Corcoran has helped thousands of families fix their furnaces and other appliances with different problems.

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.
