Sizing HVAC Systems: Why Bigger Is Not Always Better

This is an update to one of our most popular and helpful blog posts. Here’s the original: New York HVAC Systems: 8 Reasons Bigger Is Not Always Better

hvac sizing

One of the worst mistakes you can make when purchasing new HVAC equipment is choosing a unit that’s the wrong size for the space. Especially if the old unit was not providing adequate heating or air cooling, you may be tempted to go with a more powerful unit thinking it will provide more comfortable conditions.

It won’t. When it comes to sizing HVAC systems, especially air conditioners, bigger is not necessarily better. What you want is a unit with exactly the right capacity and system design to meet the needs of the space.

8 reasons to avoid over-sizing HVAC systems

Here are 8 reasons why over-sizing HVAC systems is the wrong choice for your heating and air conditioning needs:

1. The unit cycles on and off frequently.

This is called short cycling, and it’s a common symptom of an oversized furnace or air conditioner. It means your system is working much harder, using more fuel, and providing less comfortable conditions. Properly sizing HVAC systems solves this problem.

2. More breakdowns.

With the wrong HVAC sizing, your unit turns on and off so many times throughout the day that it creates a lot of wear and tear on the equipment’s parts. Any good NYC HVAC service company will tell you that as a result, you’ll have parts failing sooner than expected and increased commercial air conditioning repair or furnace repair bills. Not to mention the inconvenience and possible business interruption due to a broken heating or air conditioning system.

3. Reduced equipment life span.

All that cycling is hard on your HVAC system. If you’ve purchased a unit with an expected life span of 15 to 20 years, that unit may fail in as little as 10 years. That’s an important reason why correctly sizing HVAC systems is critical.

4. Higher utility bills.

Incorrectly sizing HVAC systems wastes energy since the equipment uses the most energy when it starts up. Because it’s starting up more times throughout the day, and has a higher capacity to begin with, you will see a spike in your energy usage.

5. Inconsistent temperatures.

The short cycling creates drafty, inconsistent heating and cooling, and you could also experience hot and cold zones throughout your space.

6. Humidity problems and poor indoor air quality.

Here’s another reason correctly sizing HVAC systems is essential. Air conditioners that are oversized don’t run long enough to remove the moisture from the air. This results in too much humidity, which can cause a host of problems ranging from furniture and computer damage to the growth and spread of bacteria, viruses and dangerous mold.

7. Noisy conditions.

That powerful unit cycling on and off all day at full blast makes a lot of noise that can interrupt your business. If you’re running a restaurant, retail location or health facility, it can even drive away customers.

8. Higher cost to purchase, operate and maintain.

Why would you pay more for something that’s going to cost you more to use and provide less comfortable conditions? This is a case where you don’t necessarily get what you pay for. Shelling out more for a higher capacity unit doesn’t get you more comfort. Properly sizing your HVAC systems gives you exactly what you need.

Sometimes less is more when it comes to sizing HVAC systems

In some cases, you may actually need a unit with a smaller capacity than you had previously. That’s because many buildings in NYC have HVAC equipment that was installed by a builder without adequate HVAC expertise. Sometimes builders make the same mistake as home and business owners, and choose a larger unit than is required. Also, when buildings are renovated there are often design and energy efficiency improvements made that decrease the capacity required for heating and cooling.

How the pros determine the correct HVAC sizing for your needs

It takes experience and the right tools to accurately determine the correct capacity for your space. To calculate the correct sizing for HVAC systems, certified commercial HVAC companies will perform a Manual J load analysis.

This service takes many factors into account, including the square footage of your space, design elements, energy-efficiency features, building occupancy patterns and how the space is used. Most quality HVAC service providers use a software tool to do this calculation.

Don’t make the rookie mistake of buying heating or cooling equipment with a higher capacity than you need. If you’re being advised to do so by an installer, get a second opinion before you waste your money.

Are you getting bad advice about HVAC sizing?

If you’re doubtful about the advice you’re getting from your current HVAC service provider, you may be thinking about switching but worried about terminating the relationship. There’s no good reason to stay with a provider that’s no longer serving your needs correctly. To learn more about how to make a smooth transition, take a look at our helpful guide to Contract Confidence: Transitioning to a New HVAC Service Provider.

HVAC Service Contracts: Controlling Time, Quality & Cost

HVAC service contracts and the project management triangle

hvac service contracts
If you’re having difficulty comparing widely differing options when evaluating HVAC service contracts, it may be helpful to use the project management triangle as a guide.

Are you familiar with the project management triangle? It’s a model that describes the relationship between three opposing constraints that impact work: time, quality and cost. It means that your choices in one area impact what you get in terms of the others. For example, if you decide you need the lowest price for a commercial HVAC service contract, that choice impacts what you get in terms of quality and/or timeframe.

hvac service contracts: choosing time, quality & cost

The rule of thumb you’ll often hear with regard to time, quality and cost is that you can choose any two, but the contractor controls the third one. When it comes to HVAC service contracts, we find that this rule breaks down: getting the best quality for the lowest cost is not a realistic option, no matter how much time you throw into the equation. However, understanding the relationship between these three constraints for HVAC service contracts is a useful exercise for focusing your priorities and clarifying what you’re getting for your money.

Modern Air Conditioning Options for Older Homes & Buildings

When you’re renovating an older building for modern living (especially one in an urban setting like NYC), adding modern conveniences can be a challenge. Air conditioning is a prime example.

Older buildings often don’t have the space to install the ductwork needed for traditional systems. Also, electrical systems may be sufficient to handle the load of today’s AC equipment. While upgrading the electric can be expensive, finding the space for air conditioning equipment is more of a problem. Doing it wrong can often mean damaging original plaster, floors and woodwork. Even in the best case, installing traditional equipment usually means giving up closet space or lowering ceilings to make room for equipment.

That’s why it’s smart to consider alternative air conditioning systems for older homes, as well as small businesses renovating older buildings. In New York City, historic brownstone townhouses are frequently renovated for both uses. Here we will discuss the problems with older solutions, and introduce 3 more modern air conditioning options for older homes that you may not know about.

HVAC Retrofit: Dos & Don’ts for Historic Buildings Conservation

New York is a historic city, settled by the Dutch in the 1600’s. There are actually quite a few structures dating back to the mid-17th century. As a result, we have many unique and beautiful historic buildings mixed in with the glass and concrete high-rises throughout the city. Many of those older buildings are protected by law and must be renovated according to strict rules for historic buildings conservation. That impacts an HVAC retrofit or replacement that’s typically needed to restore a historic space to a condition that works for a business or even a luxury residence.

Here at Arista, we have been working on historic building renovations for decades (no, not since the 1600’s but we’ve been at this for a long time!). So we’ve learned a thing or two about the unique requirements of historic spaces for HVAC.

Last week, we shared the first article in a two-part series about some of the issues you need to address with an HVAC retrofit or replacement for historic buildings. In part 1, we began with a list of 9 DOs when installing HVAC solutions in a historic space.

In case you missed it: HVAC Solutions: DOs and DON’Ts for Historic Building Preservation

Today, we’ll reveal the all-important HVAC DON’Ts for historic buildings conservation in part 2.

HVAC retrofit or replacement: DON’Ts for historic buildings conservation

1. DON’T install a new system unless you need to
Even when you’re making structural fixes or cosmetic changes to meet the needs of a new commercial tenant, it’s possible that the existing HVAC system, or components of it, can be salvaged for the sake of historic buildings preservation. That’s especially true of the heating system. For example, you may be able to keep the old radiators and replace the old boiler with a new one. Or, consider an HVAC retrofit to add AC to parts of the building not cooled by an existing system.

There are some situations where a repair or an HVAC retrofit may be a viable option for historic buildings conservation. There’s one caveat to be aware of, though: think carefully about keeping AC systems that use the old R-22 refrigerant. That refrigerant is currently being phased out due to the environmental impacts, and getting R-22 is becoming more difficult and expensive every day. That means you may need to consider a replacement system that uses one of the newer refrigerants.

 

2. DON’T forget to consider modern HVAC options for historic buildings conservation
If an HVAC retrofit will not meet your needs, don’t assume you have to replace an older system with the same type of older system! There are newer HVAC technologies that have significant benefits for historic buildings.

A variable refrigerant flow (or VRF) system is one such option. For one thing, these system don’t typically require ductwork, which can be a boon when you’re trying not to damage existing walls, ceilings and building structures. Also, the system consists of multiple air handlers which are smaller and take up less space.

What’s more, these new systems are extremely quiet, energy efficient and customizable for zoned operation.

3. DON’T cut through exterior walls
In many buildings, it’s standard practice to cut holes through exterior walls to install what’s called “through the wall” HVAC units. This is usually forbidden by building regulations for historic buildings conservation. That means an HVAC retrofit to add a small unit onto an existing system might not be an option.

In some cases, you’ll have to get creative using existing penetrations through exterior walls, and consider ductless systems.

4. DON’T alter historic architecture
Just like you have to be creative to avoid cutting through the exterior, it takes some expertise to find solutions that avoid altering architecture in a historic buildings conservation project.

Here are some of the things you should avoid doing whenever possible: avoid dropping ceilings, covering window openings, masking historic features or altering spaces to make room for HVAC equipment. If you are creative, there is usually a way to do it without destroying original architecture.

We could tell you so many stories to illustrate that point! Take a look at this previous blog to see what we mean: Residential HVAC Services: Innovation Improves Cooling in NYC Luxury Homes.
5. DON’T make condensing units or vents an eyesore
Aesthetics is a primary concern for historic buildings conservation. That includes both the interior and exterior of the space. Whether you are completely replacing the HVAC systems or only doing an HVAC retrofit, placement of equipment is extremely important.

That means, don’t put condensing (outdoor) AC units on a visible part of the roof. Don’t add vent pipes that ruin the asthetics of the roof line. If you must put a condenser in a visible area outside, at least use some creativity to hide the unit.

6. DON’T introduce moisture that can damage older structures
An HVAC retrofit or replacement, done as part of a historic buildings conservation project, requires the expertise of trained HVAC professionals. Be sure you choose a company that is experienced with older buildings, because if you’re not careful with the installation you could end up with condensation damaging the historic building structure.
Water leaks can stain walls and ceilings, and uncontrolled humidity can damage woodwork and expensive finishes.

7. DON’T skip regular preventative maintenance!
As we stressed in our part 1 article, investing in HVAC preventative maintenance is a smart move for any business, but it’s a must for those located in historic buildings. Not only are the consequences higher when something breaks (see the previously cited article about water leaks!) but the costs for repairs can be higher because it’s harder to access equipment and ventilation systems without harming building finishes.

Imagine the repair costs and building damage that you could face if a blocked drain causes a slow water leak that spreads mold through the walls before anyone notices?

That’s just one reason that our last DON’T may be the most important of all.

Owner’s Guide to Restaurant HVAC & Refrigeration Service

Like most business owners, you’re probably not an HVAC expert. Yet your restaurant HVAC is a mission critical system that your business can’t operate without. All year round, you depend on your heating and air conditioning system to keep your dining room comfortable for your customers, so they keep returning to your restaurant again and again.

Make Restaurant Comfort a Priority (It is for diners!)

Here’s one fact you probably already know: the success of your restaurant is about much more than the food. Restaurant comfort is a big issue for diners, and a prime reason they will choose to frequent your establishment, or not.

Yet (as you probably realize since you’re reading this blog!) getting restaurant comfort right it not as easy as it seems.

Just think about your own experience. It’s probably something like this: your patrons are constantly complaining about being too hot or too cold, or being bothered by drafts from your AC blowing directly on their food. And making it too loud to carry on a conversation. At the same time, your kitchen is sweltering to the point that people are ready to pass out from the heat. Even worse, you might have kitchen odors migrating to the dining room. That’s not a pleasant experience for your diners, either.

We’ve heard lots of stories like this from the many New York City restaurants we have serviced over the years. Certainly you’ve experienced your staff fiddling with the thermostat in a desperate attempt to improve your restaurant comfort. It’s even worse when you catch your customers doing that!

Facilities HVAC Replacement Strategy for the New Year

Maintaining of a large corporate property portfolio is a complex job. Take your HVAC for example: keeping hundreds or even thousands of HVAC units running is mission critical. Yet FM is responsible for more than just upkeep of all these units. Increasingly, you are tasked with:

  • Keeping the environment comfortable for employees and customers
  • Reducing business downtime due to emergency repairs or equipment failures
  • Reducing energy consumption and cost
  • Switching to more environmentally-friendly refrigerants as required by federal mandate

As equipment ages, it becomes more inefficient. As a result, it’s increasingly likely to break down, provide inconsistent comfort, and drive up energy costs. That’s why meeting the objectives above requires having a plan for proactive HVAC replacement as units reach a certain level of inefficiency.

But what about a mess you can’t see that’s lurking inside your air conditioning system? That kind of grime can do more than make a poor impression; it can lead to health problems. That’s just one reason why HVAC system cleaning is so important.

Case in point: in 2015, New York City was affected by health scare known as Legionnaires’ disease. This dangerous sickness was reported in certain large buildings and offices, and was eventually linked back to contaminated HVAC water cooling towers. Since then, legislation has been introduced to keep water cooling towers clean and prevent further infections.

  • Little to no air coming from your air conditioning registers. This is when you begin to realize something is wrong.
  • Your AC system blows warm air. Now you KNOW something is wrong!

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

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

icon_comm_kitchen2xWhen 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.

Let’s explore the reasons why a make up air unit is so essential for restaurant kitchens.

Why is Make Up Air Important for Restaurants?

Depending on the type of cooking you are doing, you might even have more than one exhaust system in your kitchen: one for heat & grease generating cooking appliances (like fryers, grills, and cooktops) and another for steam-generating appliances (such as dishwashing equipment and baking ovens).

Restaurant kitchen exhaust systems are often very powerful, removing thousands of cubic feet of air per minute. When air is removed from your kitchen, it needs to be replaced with fresh air. Without that replacement air, you wind up with all sorts of unpleasant and even dangerous conditions, which we’ll get to in a minute. The problem is compounded in newer buildings constructed to be air-tight, which prevents the natural flow of outside air into the space.
