HVAC Sizing and Why it Matters

One of the advantages of working with an experienced air conditioning company is that you’re assured of the installation of a properly sized system. But why does this matter?

There are some misconceptions about how HVAC systems work. Some might think that bigger air conditioners will cool their homes faster, but this is not necessarily the case. It’s crucial to factor in specific household needs while on the hunt for the best air conditioner for your home. For any HVAC system to truly meet your needs, sizing must be taken into account.

Let’s look at HVAC sizing and why it’s so important.

What Is HVAC Sizing?

Heating and cooling loads determine how much an HVAC system needs to work to maintain comfortable temperatures. HVAC sizing involves a series of measurements geared at determining the right size unit for your home. It considers factors like:

• Local climate zone
• Square footage
• Ductwork
• Height of ceilings
• Number and style of windows
• Amount of insulation
• Orientation of the house
• Heat-generating appliances in a space
• Number of people living in a space

These factors are used in the Manual J Calculation to determine exactly how many BTUs (British Thermal Units) of energy are needed to cool or heat your home. An HVAC technician will then choose the size of a system based on its capacity to satisfy three factors – design load, extreme load, and part load.

Importance Of HVAC Sizing

So, what’s the problem with buying an HVAC unit that’s a bit too large?

Having a little extra power isn’t bad. Such systems can handle a little extra load on extreme temperature days. The problem is that a large unit will cool your house faster and because it short cycles it cannot lower indoor humidity or filter the air sufficiently. As a result, indoor air quality plummets and you’re left with a cold but humid home. There’s also the issue of energy consumption, which from an economic standpoint doesn’t bode well for your wallet. You’ll spend more for a unit that doesn’t get the job done quite as effectively, and there is also the potential of equipment damage caused by the short cycling.

If your HVAC unit is too small, the issues will be quite evident from the start. For one, it will not have the cooling or heating power to support your home’s needs. In the summers, it will hardly bring relief from the heat outside and your home and in the winter it maybe be just a little too cold. Heating or cooling a larger home also places undue strain on an improperly sized  HVAC system, stressing its components to their limits. As a result, you’ll experience frequent breakdowns requiring emergency heating repair. What’s more, you’ll likely face an early replacement.

On the flip side, an appropriately sized system means improved thermal comfort levels, improved HVAC energy efficiency as it will use far less energy to cool or heat your home, and reduced repairs. You don’t want to end up with a system that’s working too hard to deliver conditioned air as this will severely impact its lifespan. Work with an experienced air conditioning company to get it right from the get-go. Your HVAC system is one of the largest investments you will make for your home and it’s important to treat it as such.

HVAC Efficiency - What Does it Mean?

It seems that every summer is warmer than the last one. That extra, prolonged heat means you’re turning AC on earlier in the year and for a longer duration each day – costing you more money. You know you need an efficient HVAC system, but what does this mean? And why are there so many rating systems?

When shopping for a new HVAC unit, it may be worthwhile to learn more about HVAC efficiency and what the various efficiency ratings mean.

What Is An HVAC Efficiency Rating?

An efficiency rating measures how well your AC turns electrical energy into cold air. Energy consumption through heating and cooling represents a significant portion of energy utility costs for most households. A higher rating means lower operating costs.

Here are a few of the rating systems you should pay attention to

• Energy Efficiency Ratio (EER)

The EER is a measure of the cooling capacity of an air conditioning system to the amount of energy required to power it. Systems are tested at higher operating temperatures to evaluate their performance and take into account humidity removal.

EER is a great way to assess the efficiency of small systems like window units as it measures the actual operating efficiency of a unit on a day-to-day basis.

• Seasonal Energy Efficiency Ratio (SEER)

A SEER measures usage over time rating (seasonal)  Where EER is a snapshot of a unit’s efficiency in a moment of time. If you live in a region that experiences strong seasonal changes the SEER  is the rating you should look at. Again, the higher the rating, the better. It’s also the best rating to consider when installing central air conditioning.

• Energy Star

The Energy Star rating measures how efficient an HVAC model is compared to other systems of the same size. Products are rated between 1 and 6 stars, with a higher rating indicating higher efficiency.

• Heating Seasonal Performance Factor (HSPF)

Just as SEER and EER determine the cooling efficiency of an HVAC system, HSPF measures heating efficiency. It’s the ratio of total heating needed to the amount of electricity utilized by the heat pump. You’ll want to choose a system with a higher HSPF value if you’re looking to reduce energy costs.

• Minimum Efficiency Reporting Value (MERV)

Here’s a rating that measures how well an HVAC unit ventilates your home. The MERV rating is simply a measure of how efficiently a filter removes fine particles from the air going through it. That said, all air conditioners require periodic cleaning and filter replacement to function properly. Air conditioner maintenance is the best way to prolong the lifespan of your system and ensure it keeps working as designed throughout.

Wondering what type of filter you should be using? Contact your local heating and cooling contractor for expert advice.

How To Choose The Best HVAC System

HVAC efficiency is but one of the factors you must consider when buying an HVAC system. Other crucial factors include price, system capacity, thermostat compatibility, maintenance requirements and the installing company. Consult a reliable HVAC contractor to ensure the unit you choose is the best fit for your home.

Make Sure You Get Priority AC Service When it Matters the Most

Air conditioning units require regular maintenance to function effectively and efficiently throughout their years of service. After all, summers are only getting hotter.

With reputable air conditioner maintenance companies available, you cannot afford to hand over your unit to just anybody.

So, what do you look for in an HVAC repair technician?

1. Right Training And Tools

Always seek out experience and expertise when searching for ac maintenance contractors. Odds are a company that’s been in the business for years is better equipped to handle a variety of different challenges. On that note, check if their technicians have undergone the necessary training to work with an AC system like yours.

Some questions to consider when choosing ac contractors include:

• How long have they been in business?
• Are they subcontracting any part of their work?
• What continuing education or training have they had to keep up with changing technology?
• What kind of warranties do they offer on their work?

2. Emergency AC Repair Services

There are certain times of the year when heating or air conditioning is completely necessary. In these cases, you cannot compromise on 24-hour ac repair. The last thing you want is to push your family’s comfort and safety needs to the next business day.

A good air conditioner repair company will be on your premises in case of emergencies, ready to inspect or fix whatever’s wrong in no time.

3. Trustworthiness And Professionalism

Reputation is everything in the HVAC industry. You need an air conditioning service you can trust to do the job right, every time. There are several ways to check the reputation of an AC repair and maintenance company:

• Online reviews
• Testimonials and customer references
• Opinions of friends and family members

It’s one thing to have the necessary training, expertise, and experience. It’s quite another to be the type of professional who goes above and beyond to provide customers with stellar service. Make sure they provide up-front, straightforward pricing so that you can schedule the job with confidence.

4. Location

Emergency repair services won’t do you any good if the company is too far to ensure a rapid response. Remember, the closer they are, the faster and easier the repair experience will be.

Doing It Right The First Time, Every Time

As we roll into the summer, it’s important to have an AC company you can trust. With services ranging from complete installation to maintenance and repair on all major brands, you can rely on H & H Heating and Air Conditioning for all your air conditioner maintenance needs.

Why Ductless Mini-Splits Are A Good Choice For Homes In The Mainline

The Philadelphia Mainline is known for its stunning, historic homes. If you live in one of these beautiful older homes, you know that all of that beauty also comes with some challenges. One of those challenges is choosing HVAC equipment that works well with the homes’ more traditional structures while delivering efficient central heating and air conditioning.

Luckily, there’s a type of air conditioner that tends to work really well in older homes. Ductless mini-split systems consist of an interior, wall-mounted unit, and an outdoor compressor unit. They’re efficient, easy to install, and easy to maintain. Here’s why central heat and air installation technicians recommend ductless mini-splits for homes in the Mainline.

Ducts Aren’t Needed

Many of the older homes in the Mainline were built with no or really narrow wall cavities. Running ducts through these wall cavities is nearly impossible without some extensive remodeling. Ductless mini-split systems do not require ducts to function. The air is instead cooled by the compressor and blown directly into your home.

Multiple Air Handlers

Modern homes are usually designed with airflow in mind, but this was not a priority when historic Mainline homes were built. With more traditional HVAC systems, you therefore tend to get hot and cool spots. Mini-split systems address this challenge well. You can have multiple air handling units — one in each area or main wing of your home — which helps ensure your home cools evenly.

Affordable

Because mini-split heat pump installation is quite straightforward, having one of these systems installed tends to be affordable. You don’t have to pay for someone to widen your walls or install large, expansive ducts. Plus, as long as you have an HVAC tune-up regularly, your system should last many years, saving you money on repairs and replacements.

Historic Preservation

It would be a shame to ruin the authenticity of your Mainline home with a big, intrusive HVAC system. Ductless mini-split equipment is small, unobtrusive, and easy to hide. You’ll only have several air handlers on your interior walls. Sometimes, an installer can even mount these air handlers flush with the ceiling, making them even less obvious amidst your historic decor.

Security

Some Mainline homeowners rely on window units to cool their homes in the summer. These aren’t the most secure choice; they make it easier for someone to break in through the window. With ductless mini-split systems, you eliminate this risk.

Energy Efficiency

Historic homes weren’t typically built with energy efficiency in mind, which means the current owners of these homes can use all the energy savings they can get. Ductless mini-split systems waste less energy than traditional, ducted systems. There are fewer opportunities for air leaks.

If you own a historic home in the Mainline area, consider having a ductless mini-split system installed. These systems do a great job of keeping you cool in the summer without ruining your home’s authenticity. Most local heater repair companies work on them, and they’re becoming more popular by the day. If you’re looking for home HVAC repair, AC installation, and other HVAC services in Philadelphia, contact H & H Heating & Air Conditioning soon.

Everything You Need to Know About Heat Load Testing

Has your HVAC service technician recommended heat load testing for your home? They may have suggested this service if you were having problems with your heat pump, or if you’re thinking about having a new furnace installed. The idea of heat load testing may seem a little daunting at first, but once you understand what it is and how it benefits you, its purpose becomes clear.

What Is Heat Load Testing?

The simplest way to describe heat load testing is to say it’s a way of measuring how much energy it will take to maintain your indoor temperatures to a comfortable level. That amount of energy is called the heat load. Generally speaking, the heat load is larger for bigger homes and poorly insulated homes. The heat load is lower for smaller homes and well-insulated homes.

How Is Heat Load Testing Done?

To conduct heat load testing, your heating and cooling technician will come to visit your home in person. Once there, they will look over the space, canvassing for specific information.

They’ll note the number of windows in the home and what condition they’re in. They’ll note what direction the home faces, how much insulation is in the walls and attic, and how many people live in the home. They’ll also take the local climate into account. Once they have all the information they need, they will plug it into a series of formulas to calculate your home’s heat load.

How Is Heat Load Used?

Your home’s heat load basically tells your home HVAC repair and installation team what size HVAC unit you need. Based on your home’s heat load, they can recommend several models that will serve your needs appropriately.

It’s vital to have a properly sized equipment. If yours is too small, it won’t be able to cool your home effectively. It may run around the clock, driving up your energy bills without ever cooling you down. A system that’s too large is not a good choice, either. Bigger is not necessarily better in the world of HVAC. A too-large unit will shut on and off too quickly, which puts a lot of wear and tear on the appliance and can lead to premature failure.

How Can You Reduce Your Heat Load?

If your home’s heat load is really high and your system can’t keep up, you may be able to make some changes to reduce your heat load. Start by adding more insulation to your attic. Seal up any cracks and crevices around your windows and doors that may be letting indoor air escape. Hanging some insulating curtains over older windows can help, too.

If you think you may need a new unit, be sure to hire an HVAC company that does heat load calculations. Contact H & H Heating & Air Conditioning to schedule an appointment. We offer heat pump installation, and we also fix central heating systems and air conditioners.
