The #1 Rule for Restaurant HVAC System Installation

restaurant hvac installation

If you own or manage a popular restaurant in New York City (or anywhere, really) you know that staying open is crucial to your bottom line. Not only do you lose money every hour that you’re closed, but your regular customers are forced to go elsewhere… and the last thing you want is for them to discover a new favorite. That’s why it’s a major decision to undertake a renovation or replacement of mission-critical systems (such as an HVAC system installation) that will force you to close your doors for any period of time.

AC Maintenance: The Cure For Springtime Allergies?

AC maintenance for allergies

Can AC maintenance help your allergy symptoms?

Most of us tend to think of allergies as caused primarily by pollen and pet dander. So why are people still suffering who live and work in the city, where pollen-producing plants and furry critters are in much shorter supply than in the suburbs?

The answer for many is poor indoor air quality (IAQ). AC maintenance can help reduce contaminants and allergens in indoor air and help you breathe easier.

Facilities HVAC Service: The One Way to Get Your Problems Solved

Facilities HVAC service

Getting reliable HVAC service for commercial facilities may seem like a double edged sword. It’s sometimes tricky (translation: expensive) to get everything right, but not spending the money to get it right can cost you even more in wasted energy, decreased productivity and even lost business.

Large corporate facilities are challenging to service because they have heating, cooling and ventilation requirements that can vary considerably throughout the space. For example, offices have different needs than computer rooms, conference rooms or storage spaces. Even areas that have the same function can have different needs depending on where they are in the building. In fact, the effectiveness of your HVAC system depends on many factors:

Dry Air, Indoor Air Quality & Your Health

Dry air, IAQ and health

We tend to think about high humidity as a problem that impacts both our health and our comfort. However, dry air (caused by low indoor humidity) can cause just as much discomfort as humid air. In fact, recent research suggests that prolonged exposure to excessively dry air can even cause elevated stress levels.

Dry air may also compound the impacts of other indoor air quality problems. Some studies have shown that dry air increases the negative effects of high levels of particulate matter and VOCs. 

It’s worth paying attention to the relative humidity levels of the air you breathe, especially since most buildings are not monitored or controlled for humidity levels that are too low. There isn’t even consensus on what constitutes air that’s too dry, but many experts recommend optimal humidity levels between 35 and 60 percent.

Here are some health symptoms you may experience as a result of dry air in your indoor environment, plus steps you can take to fix the problem and feel better.

Physical effects from dry air indoors

Respiratory symptoms and infections

Your respiratory system often bears the brunt of the impacts from dry air. The mucus membranes in your nose, sinus passages, and bronchial passages get dried out when fluids evaporate. That leaves them more susceptible to irritation and infection. 

When people spend a lot of time in excessively dry air, they are more likely to experience symptoms of asthma, bronchitis, sinusitis, and even nosebleeds. 

Dry air also increases your risk of respiratory infections such as colds, the flu, or even Covid-19. Experts say that viruses can survive longer in dry air, and also dehydrated mucus membranes decrease your body’s ability to fight off infection.


It’s not only your respiratory system that gets dehydrated with long exposure to air with low humidity. Your eyes, skin and throat also feel the effects:

Eye irritation. Dry indoor air can cause dehydration of the tear film that protects your eyes, leading to irritation, dry eyes, itching, problems with contact lenses, and increased susceptibility to other eye conditions.

Throat irritation. Dehydrated tissues in the throat can lead to difficulty swallowing, throat pain and inflammation, as well as hoarseness and thickened mucus in the throat.

Skin irritation. Loss of moisture in the skin can cause not only discomfort, but also skin rashes and infections, such as eczema.

Increased stress response & decreased sleep quality

Did you know that dry air and poor indoor air quality can increase your body’s stress response? A US GSA Wellbuilt for Wellbeing study found that office workers exposed to dry air (with relative humidity levels below 30 percent) experienced 25 percent higher stress levels, as measured by cardiac activity. (Workers in environments with too much humidity also showed higher stress levels, but the effects were less pronounced.) Other studies have found a correlation between exposure to dry air and production of higher levels of the stress hormone cortisol.

The Wellbuilt for Wellbeing study also revealed an indirect link between dry air and sleep quality, since the workers that experienced more cardiac stress also showed reduced quality of sleep.

How to combat dry air in summer and winter

Add moisture to the air in winter

In the winter, air gets dry indoors because of heating systems that pump warm, dry air into the space. It can be challenging to make up for the lost moisture. If your heating system can accommodate it, you may benefit from installing a central humidification system that monitors the amount of moisture in the air and maintains the optimal humidity level in your space.

When the air is uncomfortably dry, the humidifier adds moisture (water vapor) to the air circulating throughout your space via your HVAC system. The central air or central heating humidifier, which is connected to your furnace and HVAC ductwork and also hooked up to your plumbing system, produces humidity by using water and heat from your furnace.

Learn more: The Inside Scoop on the Central Air Humidifier

Keep your AC from removing too much moisture in summer

Air conditioners cool the air by removing humidity from the air. Which, ideally, should leave you with moderate and comfortable humidity levels in your space. 

However, if your air conditioner is oversized for your space, or it has problems that are causing it to run constantly, you can easily end up with dry air in your space even in summer.

If you suspect that’s the case, have your air conditioning system inspected and maintained by qualified HVAC experts. They may be able to make adjustments or repairs that can better control humidity levels, improve your comfort, and even improve your health.

HVAC Fan: Should You Keep It On 24/7?

Your thermostat has two settings that control the HVAC fan that circulates heated and/or air conditioned air throughout your space. You can set it to AUTO, which automatically turns the fan on when your AC or furnace is running. Or, you can set it to ON, which tells the system to keep the fan running all the time.

Which should you choose? Let’s take a look at the pros and cons of running the HVAC fan 24 hours a day, versus only when your heating or cooling system is operating.

Benefits of keeping the HVAC fan ON

More consistent temperatures with the HVAC fan on

When the HVAC fan runs constantly, it has a chance to keep moving heated and cooled air evenly throughout every area of your home or commercial space. That can help to eliminate hot or cold spots and improve comfort.

Running the HVAC fan can eliminate stuffy air & control odors

During spring and fall when temperatures are moderate, your heat or air conditioning may not be running very often, if at all. Especially in city buildings that are well sealed and may not have windows that open, the indoor air can get stuffy with a lack of air circulation. Running the HVAC fan can help keep the air feeling fresh, and also help to dissipate odors.

Improved air quality with constant filtration

When the HVAC fan runs all the time, more air is circulated through your HVAC filters (and air purification systems if you have them), which can help to reduce airborne contaminants. That can mean less allergens like pollen and dust, VOCs, pollution, and even mold and bacteria that cause illness.

One caveat to be aware of: the benefit you gain from filters depends a great deal on the type of filter your HVAC system has. Standard HVAC filters aren’t meant to trap particles as tiny as viruses, for example, or even some types of pollen. They are primarily meant to keep dust and debris out of your HVAC system. However, filters with a higher MERV rating can remove more types of particles, as long as your system can accommodate them.

If you have an air purification system installed in your HVAC ducts, you will benefit much more from keeping your HVAC fan running.

IAQ Alert: Is Your HVAC System Contaminated?

Less stress on the HVAC fan motor

It may surprise you to learn that running the HVAC fan all the time can actually extend the life of the fan. That can be true because it eliminates the stress of the motor frequently turning on and off every time your furnace or AC starts up or shuts down.

Downsides of using your HVAC fan all the time

Higher electricity costs

Running the HVAC fan 24/7 may use quite a bit more electricity than running it only when your HVAC system is operating. Depending on your space and your system, that could cause a noticeable jump in your electric bill.

More frequent filter changes needed

With air circulating through your space, your ducts and your HVAC filters, those filters are going to get clogged faster. You’ll need to check and change or clean your filters more frequently.

Here’s some help with how to do that: 

Fall Furnace Maintenance: How to Change Your Furnace’s Air Filter

Why and How to Change an AC Filter

Air temp from the registers when the HVAC system’s not running

When your furnace/air conditioner fan is running but the heating/cooling system is not, the temperature of the air coming from your registers may be warmer than you’d like in summer or cooler than you’d like in winter. That might not be a big problem unless you’re sitting right next to the register, but it’s something to keep in mind.

Less humidity control in summer

Not to get into the technical details, but suffice to say that the air conditioning fan blowing all the time can actually impede your air conditioner’s ability to control humidity in summer. If you notice that happening, you can decide to turn the fan back to AUTO until the problem is resolved.

So which HVAC fan control option should you choose? It depends on your situation and your priorities. 

Also, be aware that no matter which way you set your fan, there’s something else you can do to optimize your comfort and keep your system performing efficiently and effectively: get regular maintenance.

HVAC maintenance helps keep your systems performing well

Have your heating and cooling systems inspected, cleaned, and tuned up at least every year, and possibly more often depending on your system and its usage. The most cost-effective way to do that is with a yearly maintenance agreement that’s customized to your specific needs. It’s a small investment that pays off in big ways:

  • Your system stays in good condition, so you can prolong the life of your equipment.
  • Your equipment runs more efficiently, which reduces energy consumption.
  • Minor issues get fixed proactively, so they don’t turn into bigger, more expensive problems.
  • Maintenance helps to prevent system downtime that disrupts your home or business.

Is Too Much Humidity Hurting Your Health?

You may have read recent research that suggests raising indoor humidity levels may help to deactivate coronavirus particles. During the winter months when our spaces are closed up and heated, humidity levels can drop to extremely low levels (as low as 20 percent).

Unfortunately, the COVID-19 virus has been shown to thrive and remain viable for longer periods in these low-humidity conditions. (Controlling humidity is just one way HVAC can help in the fight to prevent COVID. Get our guide to HVAC Strategies for COVID to learn more.)

8 Reasons Restaurants Need a Make Up Air Unit For the Kitchen

What exactly is a make up air unit for a kitchen?

When you add a make up air unit for your kitchen, it adds replacement air for what’s being drawn out of the kitchen by your exhaust hoods.

What is make up air? Simply stated, a make up air unit pulls air in to your space from outdoors and conditions it to the indoor temperature, to replace air that’s pulled out by your kitchen exhaust equipment. Without it, you get back drafting, poor temperature control, negative air pressure and air quality problems. Poor ventilation can also contribute to the spread of disease.

The High Cost of Poor Workplace Temperature Control

woman affected by cold workplace temperature

According to IFMA research, an uncomfortable workplace temperature is the number one complaint of office workers about their workplace environment. Actually, it’s both number one and number two (people complain most about being too hot AND about being too cold).

This complaint is really not surprising when you consider that 40% of office buildings–especially here in New York City–have HVAC systems that are somewhere between 16 and 30 years old. During that time, building tenants have changed, usage of the space has changed, more employees are packed into the same amount of space, and there’s a lot more heat-generating technology in place. So many of these systems were never designed for the current conditions.

It’s important to realize that workplace temperature impacts more than your employees’ comfort. Here’s what you’re risking when you have HVAC equipment that’s failing to properly control the temperature in your workplace.

Air conditioner power consumption: how much are you using?

As anyone who has seen their electric bill skyrocket in the summer will know, your air conditioner power consumption can be a big, unpredictable cost. To try and understand your costs, you can start with your AC unit’s power rating (check the label on the condensing unit), which will tell you how much power it uses under perfect conditions. In real life, conditions are rarely as consistent as that.

There are many factors that affect how efficient your AC is and how much power it uses, including age and condition of the unit, the layout of your space, design of the air ducts, how air-tight the space is, and of course the weather. That’s why calculating your expenses is never an exact science.

Airflow issues are among the most common HVAC problems. If you suspect you have HVAC airflow problems, you’re probably experiencing one or more of the following symptoms:

  • Hot and cold spots throughout your space. This is often one of the first signs of HVAC airflow issues.
  • Pressure imbalance. Do you have doors slamming by themselves, strange whistling noises and drafty areas? These are symptoms of air pressure problems caused by poor airflow from HVAC systems.
  • No air coming out, weak air or low airflow from vents in your house or commercial space.The problem could be throughout the space, or you could have one AC vent not blowing air in one room. This is when you begin to realize something is wrong.
  • Your AC system blows warm air. Now you KNOW something is wrong!

If you ignore the problem for too long, the strain on your system can lead to compressor failure. The compressor is like the heart of your air conditioner, and when it goes, there’s a good chance you’ll need a new unit.
