5 CAUSES OF FROZEN HVAC COILS

News flash, it is Summer, it is HOT! The last thing you would expect to see is ice on the coils of your HVAC system.

Below are a few potential causes for frozen coils on your HVAC system:

  1. Dirty air filters may cause frozen coils

Your HVAC needs clean airflow throughout the system to function properly. Dirty filters can obstruct air from getting in and out of your system. If the air does not circulate around the coils, the coils get too cold, and lead to ice accumulation on the coil.

  1. Broken fans can decrease airflow and cause coils to freeze

Even if your filters are clean, it will not help unless the fan is pushing air through the system.

If your fan has a broken motor, or dirty blades, this can cause a decrease in airflow that could lead to frozen coils.

  1. Condensate line issues

Condensate lines are the part of your HVAC system that drains away the excess moisture from humidity. This moisture, condensed into water, travels through condensate lines to drain. Lines that are clogged, broken, or do not have the proper pitch, can freeze resulting in ice accumulation. A common place for obstruction happens near the evaporator coil, which is the coldest part of the HVAC.

  1. Malfunctioning thermostats

Your thermostat works with your HVAC by regularly checking the temperature and controlling the amount of conditioned air your building needs to stay at the desired temperature.

If the thermostat is malfunctioning or does not read the correct temperature in the space, it could cause the unit to run longer than needed. Left unchecked, an overworked HVAC unit could develop frozen HVAC coils.

  1. Refrigerant leaks are a common cause for frozen coils

Refrigerant is the chemical that runs through your HVAC coil, it regulates the temperature by absorbing heat inside of the space. When refrigerant leaks, it will affect the cooling process of your HVAC system, which causes condensation on the coil to freeze.

BUILDING AUTOMATION SYSTEMS (BAS) -THE BENEFITS

The benefits of Building Automation Systems (BAS), sometimes referred to as Building Control Systems (Controls), vary, but the reasons usually fall into three main categories:

  1. They save building owners money
  2. They allow building occupants to feel more comfortable and be more productive
  3. They reduce a building’s environmental impact

SAVING MONEY

A Building Automation System can reduce the utility bills for building owners. A more energy efficient building simply costs less to run.

Estimated energy savings from simply monitoring occupancy range from 10-30%, which, based on the size of your building, can create significant savings on utilities each month.

Typically, building owners or facility managers find that the money a BAS saves them can over time offset the installation and implementation of the system itself.

Also, optimizing the operation of the equipment for your facility can extend the life of the equipment, meaning reduced replacement and maintenance costs.

 COMFORT AND PRODUCTIVITY

Efficient control over the building’s internal environment can create a healthier and more pleasant work environment. Furthermore, studies have shown that improved ventilation and air quality can have a direct impact on productivity and a business’s bottom line.

 ENVIRONMENTALLY FRIENDLY

By reducing energy consumption, a BAS can reduce the output of greenhouse gases and improve the building’s indoor air quality, the latter of which ties back into bottom line concerns about occupant productivity.

AVOID FROZEN PIPES IN YOUR COMMERCIAL FACILITY

AVOID FROZEN PIPES IN YOUR COMMERCIAL FACILITY

 

For many building owners and facility managers, frozen pipes can be one of the most significant problems that occur during the cold months.

 

Items that can contribute to frozen pipes:

  • PIPES THAT ARE NOT WELL INSULATED. Insulated pipes keep the warmth in and the cold out. If pipes are not insulated, it is much more likely that the water inside them will freeze.
  • PIPES LOCATED IN NON-CLIMATE CONTROLLED AREAS OF YOUR FACILITY. Commercial buildings may have areas that are not climate controlled or have poor heat distribution.  These areas include basements, exterior walls, or more remote spaces.
  • PIPES FREEZE BECAUSE THERE IS NO WATER CIRCULATION. Water supply lines and drainage pipes can be sensitive to freezing temperatures. These lines/pipes often have water sitting stationary for long periods of time.

 

TIPS TO HELP PREVENT PIPES FROM FREEZING IN YOUR FACILITY

  • INSULATE THE PIPES. Use pre-formed pipe sheaths or wrap the pipes with standard blanket-style insulation.
  • INSULATE THE BUILDING. It is also a good idea to insulate areas that are likely to get cold. Increased insulation can also make your building more energy efficient.
  • USE HEAT TAPES. Heat tapes are lengths of wire with embedded heating elements that warm up to heat pipes.  These can be wrapped around your pipes to prevent freezing.
  • SEAL AIR LEAKS. Make sure to seal any cracks, holes and gaps that allow cold air to blow in on pipes.

ARE MY PIPES HAUNTED?

Squeaking, creaking, vibrating, and banging pipes can make you feel like you are living with ghosts or goblins. However, more than likely…… it is nothing supernatural, but just sounds that could be explained by issues in your water pipes.

 

CREAKING AND TICKING SOUNDS

“Creaking” sounds can be caused by hot water traveling through copper pipes. The hot water causes the pipes to expand causing them to rub against any surface surrounding them.

Once copper pipes begin to cool off, they start to contract and may cause a ticking or creaking sound. A possible resolution to the “Creaking” & “Ticking” noises could be an adjustment to your water temperature or wrapping the pipes to lower or eliminate the sounds.

 

POPPING SOUNDS

Mineral buildup in your water pipes can cause “Popping” sounds. The buildup creates a rough coating on the inside of the pipes, which results in the forming of air bubbles that burst and pop when the water heats up. The source of these “Popping” sounds may be your water heater. A Commercial Plumber will know how to flush your water heater to reduce sediment or can install a new water heater if needed.

 

VIBRATIONS, BANGING, AND CLANGING SOUNDS

A common and easily manageable issue that can contribute to many of the sounds and vibrations in your systems water pipes is water pressure. Loosely attached water pipes sometimes vibrate due to the pressure of traveling water. Pipes that vibrate against solid objects can produce a loud vibrating or knocking sounds.

A sudden banging or clanging throughout your water pipes could be caused by a closed valve that suddenly halts the flow of running water causing a hydraulic shock wave to travel through the pipe until it hits a solid obstacle with a loud bang! A Commercial Plumber could help to solve the issue.

SIGNS OF AN A/C WATER LEAK

Have you found a puddle of water in the mechanical room or notice a wet spot on the ceiling tile?  If so, something is wrong.  Likely, you’re A/C has a leak!  What do you do now??!!

First, don’t hit the panic button!  There are several possible causes for an A/C to leak water and many of them are not a difficult and expensive repair.

However, it is important to act quickly, because a leaking A/C can cause major damage to walls, ceilings, floors, furniture, and could lead to major repairs or equipment replacement.  Proper Preventative Maintenance provided by your trusted Commercial HVAC Service provider can help prevent most of the issues listed below.

 

COMMON REASONS WHY AN A/C MAY LEAK WATER

  1. FROZEN COILS – Probably the most common reason an A/C leaks water. Locate your indoor air handler and look at the evaporator coils. If you see a block of ice, turn the unit off immediately and call your Commercial HVAC professional for a service call.

 

  1. DIRTY COILS – When regular maintenance is neglected, it is common to find dust, grime, and dirt on the A/C coils. The dust, grime, and dirt buildup can impede the flow of water to the drain pan.

 

  1. DAMAGED INSULATION – Insulation on your coils are designed to keep the accumulated condensation flowing down the coil. However, when the insulation gets damaged with cracks or holes, water can drip directly from the coil instead of flowing to the drain pan as it should.

 

  1. DISCONNECTED DRAIN LINE – This problem usually stems from a poor installation. If you’re A/C’s drain line wasn’t attached correctly, it can become disconnected and lead to an A/C water leak.

 

  1. CLOGGED DRAIN LINE OR TRAP – Here is another issue due to lack of maintenance. The condensation collected by your air conditioner carried dust and debris into the drain line and drain pan. This causes the drain line to clog and results in the water to backing up and overflowing/leaking.

Where Is Your Water Pressure?

There is nothing more frustrating than going to wash your hands and you can’t rinse the soap off due to low water pressure.

Sometimes the low water pressure issue isn’t just located at the faucet, it is affecting the entire facility.  When your facility is impacted; it can slow work, create an unsanitary environment, or even cause a total shutdown.   A Water Leak Detection test completed by one of our professional Plumbers may be the answer!

 REASONS THAT LOW WATER PRESSURE MAY EXIST:

  • It’s not you, it’s them…. Is the issue on the City’s (Water Providers) side? Commercial lines are subject to clogs, corrosion, leaks, damage, and other malfunctions that will affect your water pressure. Leak Detection will help to determine if the problem is on your side of the water meter or on the City’s (Water Providers) side of the water meter.
  • You may have a leak! Obviously, leak detection can locate the leak and a professional plumber will provide a solution to the problem to prevent further damage and restore the water pressure to your system.
  • Your pipes are corroded. Pipes don’t last forever. As old, galvanized steel pipes wear out, they develop leaks.  Leaks can contribute to a loss in water pressure.  A qualified plumber will upgrade your plumbing system, if necessary.
  • Your pressure regulator is on the brink. Your pressure regulator is a control valve that regulates the flow of water through your plumbing system.  When it fails, either the water pressure is too high, possibly damaging pipes, or the water pressure will drop dramatically.
  • Your water heater is broken. If you experience low water pressure when using hot water only, there is a good chance that the water heater is the problem. A professional plumber will know if it’s time to replace the water heater.

HOT AS A FIRECRACKER

HOT AS A FIRECRACKER!! DON’T BE A DUD ON HVAC MAINTENANCE

The dog days of summer are in force! Is your air conditioning system ready for the challenge?  HVAC system maintenance helps keep your system running reliably and efficiently.  Your HVAC system maintenance is crucial for a comfortable and smooth summer.

HVAC preventative maintenance is more important this year than in past years due to many office closures for much of 2020.  During these office closures, many HVAC systems were not properly maintained.

Consider this: if you had a car that sat in the garage all winter, would you feel comfortable taking it on a long trip without getting it checked out first? If you did, you may be risking a breakdown or a major headache. By running your HVAC system without preventive maintenance, you are taking the same risk.

HVAC MAINTENANCE: GET READY FOR THE HEAT!

Here is why an HVAC preventive maintenance is critical for both your system and your bottom line:

  • The typical life of an air conditioning system is about 15 years, but dirty, neglected systems deteriorate much faster. Regular cleaning and care prevent breakdowns and premature failure of equipment.
  • Accumulating debris in drains and condensation lines can lead to water leaks and system failures. Water leaks can also cause additional damage to surrounding structures and health problems for employees.
  • The demand for appointments in peak season can mean long waits in sweltering temperatures if your equipment fails. HVAC preventive maintenance helps prevent repair issues that cause business interruption and lost revenue.  Ask about our Preferred Service!
  • Dirty vents and air filters, clogged condensate lines, leaking vents and poor drainage all decrease the performance of your air conditioning system. These issues can cause your HVAC system to work harder and use more energy to keep your building cool.  Preventive maintenance helps your HVAC system run efficiently and reduces energy consumption.

TRUST THE EXPERTS FOR HVAC MAINTENANCE

Some business owners try to save money by doing maintenance “in-house”.  Yes, you can change air filters on your own, but most of the tasks on a maintenance service are best left to a professional.

Just like the old car in the garage, you can probably change the windshield wipers blades, but you will be safer and save more money in the long run if you have an experienced mechanic take care of the engine.

HVAC systems are complicated systems with many moving parts, refrigerant, and electrical components.  They require a certified technician to resolve issues and clean all the components.  Build a long lasting relationship with your HVAC provider. It will be beneficial to you!

HVAC Cleaning is a MUST! Here Comes the GERMS!!

There is no question that air quality is vital to our health, especially for people with underlying health conditions. As cities grow and as we move back into our offices, air quality will be an ongoing challenge.

 

HVAC cleaning and maintenance is essential for air quality especially for commercial spaces that were closed due to the pandemic.

Here are some reasons to take advantage of HVAC cleaning and maintenance:

AIR POLLUTION DOES NOT STAY OUTDOORS:

 Although most cities in Alabama aren’t known for high air pollution, there is still plenty of “fine particle matter” floating around. That matter creates poor air quality inside our facilities. Dust and particles from boilers, construction activity, or outside air can find their way into your HVAC system. Filters that are not changed on a regular basis can restrict air flow and allow those particles to enter the air stream causing allergies to flare or upset other respiratory conditions.

 

THE OTHER “STUFF” IN THE AIR WE DON’T THINK ABOUT:

Besides particles and matter that get into your HVAC system, there is other “stuff” like bacteria, pet hair, and dust mites that build up over time, causing allergies and contributing to poor indoor air quality.

HVAC cleaning and maintenance can help control the other “stuff” and keeps your HVAC system operating effectively.

 

AIR CONDITIONING CLEANING SHOULD BE ROUTINE:

Your air conditioning system is an investment and works hard every day. It makes sense to keep it running well with a routine maintenance. Performed regularly, a routine maintenance will remove the contaminants that negatively impact your indoor air quality.

 

Make sure you have a positive relationship with a HVAC company! This will help eliminate the “germs” coming back as your employees return to the office.

A STICKY SITUATION!

HUMIDITY AND POOR AIR QUALITY

Humidity is a key component of air quality. Indoor air quality can drastically affect a person’s health, comfort, and the ability to function at their best while at home or at the workplace.

 

HUMIDITY AFFECT THE WORKPLACE

Workplaces with inadequate ventilation and poorly functioning air conditioning systems often suffer from high humidity. In spaces with a high relative humidity (over 50% to 60% based on temperature), the problems can get serious.

Poor indoor air quality caused by humid conditions can cause your employees to experience a wide variety of illnesses and symptoms:

  • Damp air results in musty smells, but can also cause symptoms ranging from stuffy sinuses, eye irritation, wheezing, skin irritation and/or dangerous lung infections.
  • Mold spores, dust mites and other allergens grow in high humidity and can adversely affect people with asthma
  • Warm temperatures combined with high humidity make people feel warmer and can lead to an increase in heat-related illnesses, including heat rash, muscle cramps, heat exhaustion and even heat stroke.
  • Bacteria and viruses that cause respiratory infections, including COVID-19, thrive and spread in humid conditions that are either high or very low.

Humidity can also cause damage to the building and its contents due to condensation.

 

PARTNER UP WITH YOUR HVAC PROFESSIONALS

The American Society of Heating Refrigeration and Air Conditioning (ASHRAE) recommends temperature ranges of 68° to 78 ° at 50% relative humidity for a comfortable and safe work environment. Improving air quality in your building means working hand-in-hand with qualified professionals who understands and can work on equipment that moves air. A correctly designed and properly maintained HVAC system keeps humidity at correct levels.
