How to fix common HVAC issues in commercial buildings

A reliable HVAC system is essential for every business to ensure its employees are productive and customers are happy.

 

Tenants complain, customers leave and employees grumble when there isn't enough heating, ventilation, and air conditioning.

 

Commercial HVAC systems must also be energy-efficient HVAC Installation Long Island . This helps businesses maintain a healthy bottom line, and lessens environmental stress.

 

Any business looking to keep overhead costs down must consider cost.

 

According to energy.gov (a U.S. Environmental Protection Agency branch), "Space cooling accounts roughly 15% of electricity used commercially buildings -- second only lighting,"

 

There are big differences between commercial and home HVAC systems

 

Many people mistakenly believe that a commercial HVAC system can be a larger version of a residential one.

 

Commercial systems must cover a larger area than your average home and meet many different demands.

 

Think of a restaurant, a hospital or office building. Each one has a different HVAC requirement than the average residence.

 

Commercial HVAC systems require multiple thermostats, more wiring, and more powerful systems.

 

* There are more differences: 

 

Commercial spaces have higher roofs and receive much more foot traffic than residential homes. This is something the HVAC system must adapt to.

 

The bottom line: A commercial HVAC system may be more expensive than a residential one to meet business needs.

 

* Location is another difference.

 

While a residential HVAC system can be installed in a backyard, a commercial HVAC system works best when mounted on a roof. This allows for space savings, noise reduction, and maintenance efficiency. The business can continue uninterrupted even while technicians are at work.

 

7 problems with commercial HVAC

 

Maintenance is a common problem in commercial HVAC.

 

You can minimize or avoid them by checking your system regularly.

 

Filters should be replaced or cleaned regularly, for example. Filters can become clogged, which can lead to poor air quality and a sub-functional HVAC system.

 

1. Freezing of evaporator coils

 

Suspect No. 1 is often dirty air filters. 1. When your evaporator coils are frozen.

 

Next, check the refrigerant level to see if it's too low. This could be a sign of a leak in the refrigerant line.

 

2. Fuse blow

 

If blown fuse become common, don't just flip the breaker on and off. Blowing fuses could mean that your compressor or motor are no longer protected from overheating.

 

3. Blower is always running

 

If the blower is not turning on and the thermostat is set to "auto", you may have a stuck fan.

 

4. Thermostat problems

 

Most thermostat issues can be fixed quickly. The thermostats can be damaged or worn out, or they may be accidentally turned off or not set correctly.

 

5. Leakage in the compressor

 

A compressor that starts to run louder than usual could be a sign of a refrigerant problem.

 

6. Dirt on condenser coils

 

Condenser coils can reduce airflow in your business if they get dirty.

 

7. Inefficiency of burners

 

Heat exchangers can become clogged with rust particles, soot, and other debris, which reduces the burner's efficiency, and makes the system more difficult to use.

 

Maintenance savings

 

To ensure that small problems are quickly fixed, it is important to have maintenance checks done periodically by either the building's staff members or a professional contractor.

 

However, there are some issues that can lead to a commercial HVAC system failure. They can lead to costly and expensive cooling or heating problems if they are not addressed quickly.

 

Problems with the compressor

 

The compressor is often the most costly component of a system. It relies on other components to maintain heat, air-cooling, and ventilation in good order.

 

Low refrigerant can cause the compressor to slow down and overheat.

 

Call a certified technician whenever refrigerant is involved. Federal law requires that you have a license to handle refrigerant chemicals. This can cause toxicity, flammability, and asphyxiation.

 

Problems with snowballing

 

Small problems can quickly become big problems if they are ignored.

 

Dirty filters, dirty coils and other broken parts can all reduce a compressor's efficiency.

 

Overheating increases because dirt makes it harder for the compressor to work. Exercising too hard can reduce the unit's lifespan.

 

More HVAC problems and solutions

 

Each commercial HVAC troubleshooting guide suggests regular maintenance to clean and check parts.

 

Here are more suggestions

 

* Duct aging: As time passes, ducts can develop leaks or become dislodged from vibrations and rodents. Some of the treated air then escapes from the rooms it is intended to heat or cool.

 

The system will work harder to correct the damage if the ducts are damaged.

 

A pressure test can often determine if there is a problem.

 

* Noisy belts: The belts that serve the evaporator can vibrate loosely. This causes fan rotation to slow down. Commercial HVAC belts can make noise when they become loose, just like an automobile fan belt. They are easy to repair.

 

* Evaporator problems

 

Evaporator coils containing refrigerant help remove heat from buildings. These coils are extremely cold. The refrigerant absorbs the moisture and warm air, cooling the building and lowering the humidity.

 

However, refrigerant could leak from the coils and cause the building to not have enough cooling. Common signs include unusually high utility bills, frozen evaporator coils, icy refrigerant line noises, and unusually loud refrigerant lines.

 

Low airflow: A system that does not have enough airflow can freeze. This issue can cause damage to the compressor and you need to address it quickly.

 

Closing vents or dirty filters can cause low airflow. To maintain an even airflow, vents in unoccupied rooms should be left open. ).

 

Maintenance staff of a building or contractors should replace dirty filters and clean evaporator coils regularly to look for leaks.

 

Concerns of the air handler: The job of an air handler is to condition and circulate air.

 

Common problems with air handlers include dirt, a failure of the blower motor or a related piece or equipment or obstructions in condensation drain lines or reduced airflow.

 

If the blower motor is working fine, it could be the control board, capacitor, or relay that are the problem.

 

Puddles on the roof - Make roof checks part of your regular maintenance. Puddles of water can be caused by condensation from HVAC units.

 

A tool to save energy

 

The "economizer", an energy-saving device, is a new feature in modern air-handlers. Instead of running the air conditioner compressor, it cools the building with cool outdoor air.

 

Its usage is limited by the seasons, temperature, and humidity which are all measured by sensors.

 

The economizer is activated when the outside air reaches a comfortable temperature and the air conditioner turns off. The economizer uses less energy and cools the building, so you get some air conditioning for free!

 

Dirt can also hinder the economizer's ability to perform at its best. The economizer is part of an outside unit and should be cleaned regularly.

 

Commercial HVAC

 

The older commercial HVAC systems are no match for the newer, more technologically advanced systems. Commercial HVAC systems today are more efficient and less susceptible to failure.

 

An economic cost comparison might show that a new system is more affordable than an older commercial HVAC system.

 

Benefits:

 

* Increased energy efficiency which will lower utility bills

 

* Lower maintenance costs. The new system will be covered by warranty.

 

Planning is essential

 

There is no single commercial HVAC system that works for all. Therefore, it is important to plan installation and maintenance in detail.

 

When planning, you should take into account the intricate details of furnaces, compressors and furnaces as well as duct systems and refrigerants.

 

Ventilation has been a problem since the beginning. However, Covid-19 has raised awareness about air quality. Therefore, vents, airflow, and filtering deserve extra attention.

 

Poor indoor quality could be due to a common problem with the air handler - dirt, water, or rodents getting into a blower compartment.

 

Other important factors include the number of business needs and the power needed for a system's operation to work well.

 

Smart planning, correct installation, regular cleaning, and inspection can prevent most commercial HVAC problems.

 

Questions

 

Before installing commercial HVAC, planners must consider how the building will be used.

 

* Do you plan large open spaces or smaller spaces?

 

* The building will be used from 9-5 weekdays to 24/7.

 

* Are you a residential user?

 

* Does your product require special temperature and humidity control?

 

These issues all involve systems, equipment, drainage, and other factors. Commercial HVAC is a complex but vital component of a company’s success.

 

Another question is: Do you prefer ducted or ductless HVAC? Each system has its pros and cons.

 

The right size is important

 

Commercial HVAC systems should be selected based on their needs and not just size.

 

Planning will require studies to find the right fit. It won't work if the unit is too small. It will waste its time if it is too large.

 

Many commercial HVAC systems are too big, which can make them unproductive.

 

According to the Consortium of Energy Efficiency (CEE), at least 25% of rooftop HVAC units are too large, which can lead to increased energy costs and wear. Properly-sized equipment can dramatically reduce energy costs, increase the equipment's life, and reduce pollution.

 

Life expectancy of an unit

 

A commercial HVAC system should last between 15 and 20 years, according to budgeting.

 

This number will vary depending on how the installation is done and what maintenance is performed.

 

Commercial furnaces

 

According to most experts, a commercial furnace should last at least 18 years, depending on its components and how well they are maintained.

 

You should be aware of cracks and rust that can build up when the heat is turned on.

 

Another sign of poor aging is the furnace's uneven heating, which can cause it to heat unevenly.
