How to Determine What Size HVAC Unit You Need

  • By Admin .
  • 14 Feb, 2017

When it comes time to buy a new heating or air conditioning unit for your home, one thing most people probably won’t know is what size unit they need. Choosing the right size HVAC unit for your home is very important in order to maintain a comfortable, even temperature throughout the home while ensuring you aren’t wasting money on cooling and heating costs.

If your heating and air conditioning unit is too small, it won’t be very effective in creating your ideal indoor temperature. It will also work harder than a larger unit, which means it will be running more often than needed, all the while using excessive amounts of energy. A unit that is too large will cost more to run as well as leave the air with excess humidity.

When you’re choosing a contractor to replace your air conditioning or furnace, make sure to ask them about unit design and sizing. How they approach the task is as important as their technical acumen, as there are many factors to take into consideration when properly sizing a new HVAC system or unit.

Determining the Square Footage of Your Home

Knowing the square footage for each room is important for proper central air conditioning system sizing. The easiest way to accurately determine the square footage is to review your property tax statement or contact your county auditor’s office. If this information isn’t accessible you or your contractor will need to measure each room using the following steps.

In order to measure the square footage of each room for room heating and cooling units, or to add them together for a central unit, you will need a tape measure.

Anyone who has worked in an office environment knows how chilly the workspace can get for, seemingly, no reason at all. Blasting the air conditioning is often regarded as just another standard trait of an office building that its employees have to endure. You don’t have to let your office’s air conditioning zeal stamp out your ability to concentrate and be productive, though! Boost your motivation and accuracy at work by ensuring you have all the tools you need to keep warm at your desk.

Why Does My Office Cubicle Feel More Like an Ice Cube-icle?

Offices are, more often than not, utterly freezing most days. Although tracking down the nearest thermostat may seem like a great idea, many companies may be particularly picky about their employees fiddling with their air conditioning. The tendency toward arctic temperatures is actually due to real building regulations, though that doesn’t necessarily mean this particular practice is still relevant in this day and age.

The reason most offices blast their AC all year long is because of building regulations from the 1960s and 70s. These recommended a chilly office temperature to offset the warmth of a full business suit because men still made up the bulk of the workforce at the time.

Because these outrageously dated regulations don’t work for today’s workforce, various studies have been conducted to pinpoint the most comfortable and productive temperature for the 21st-century office environment. Cornell University’s study found that accuracy improved and motivation increased when the temperature was raised to 68 to 77 degrees.1

So, why do offices continue to stick to their 40-year-old regulations if they know they don’t work? Upper management in companies is typically filled with people who either worked during the 60s and 70s or were taught by those who did. They’ve adhered to certain rules for decades and see little point in changing. In short, old habits die hard.

Great Ways to Keep Warm at Work

Even if your company’s management refuses to turn the dial on their air conditioning, staying warm in a freezing office is easier than you may think. If you find it’s difficult to focus due to the cold, it may be time to take a brisk stroll around the building or to the break room. Any amount of movement can increase your heart rate and pump blood to the chilly areas of your body, such as your fingers and toes. For extra warmth when you’re seated, you can bring in a sweater or scarf to keep at your desk when the cold is too much.

Some employees may raise the bar even more by keeping heated slippers or fingerless gloves at their desk. Though you may be unable to walk around the office in house slippers all day, snuggling up at your desk is a great way to feel warmer when you have to remain still.

Cozy Up During the Work Day with AirCon Service Company

Your home’s temperature is even more important if your office feels like the North Pole. You rely on it to provide comfort when you’re free of the freezing grip of the workplace. Houston residents can maintain the perfect temperature all year round with maintenance and upgrade services from the air conditioning experts at AirCon Service Company.

Your home air conditioning system uses a lot of energy, especially during the summer. To try and save money on their cooling bills, some people close the registers and vents in unoccupied rooms. The assumption is that doing so decreases the amount of cold air allocated to rooms where it’s not needed, allowing the air conditioning system to work less. While the logic might seem sound, it’s actually incorrect. Closing you system’s air vents does not save you money. In the long run, it can actually lead to safety issues and costly repairs.

How AC Systems Work

Your heating, ventilation and air conditioning (HVAC) system is powered by an electric motor that blows air through the system. It pulls air from the house through return ducts and then pushes it back into the house via the vents. Each system is designed with a motor capable of blowing air against a maximum level of pressure. Excessive pressure forces the motor to adjust its power and output in order to maintain proper air flow.

When a homeowner closes the vents that blow air into the home, it’s forced back into the system. This puts additional pressure on the blowing motor. Over time, this building pressure can cause a number of problems for your home and HVAC system.

High-Pressure Risks

Air that backs up into the HVAC system’s motor isn’t content to just hang out until it’s blown into another room. The more vents you close, the higher the pressure builds. An electric motor will be forced to use more energy to control the flow of air. Once the pressure becomes too great, cool air will start leaking out of the duct system wherever it can. Most home ductwork isn’t perfectly sealed. The air escapes through small cracks in the ductwork, blowing into your attic or other spaces within the home, wasting energy that was intended to cool your living spaces.

A buildup of cold air can actually permanently damage your HVAC system. Cold air is created when uncooled air passes over cooling coils, which bring down the temperature. Too much cold air in one place can actually freeze the coils, causing the system to shut down.

With the hot summer months just around the corner, now is the perfect time to make sure your home’s air conditioning system is working properly and efficiently. Any issues detected by a certified technician should be fixed as soon as possible, but when is it better to have your system completely replaced instead of repaired? Here are some important factors you should consider before paying to fix your current home air conditioning system.

Age of the Current System

Even if your home’s air conditioning seems to be running perfectly, most systems have a somewhat limited lifespan. Manufacturers recommend you replace your AC system every 10 to 12 years. Once it starts to hit that age, you can expect more frequent and costly repairs in your future. Investing in a newer air conditioning unit may allow you to save time and money by eliminating the need for future repairs. Modern systems are designed to last longer but also contain newer, better cooling technology. By replacing old cooling equipment you’ll be able to take advantage of new features and energy savings.

Frequency of Repairs

New air conditioning systems might be better designed and constructed, but systems of all ages run the risk of breaking down. While repairing your AC unit can increase its longevity, at some point it, might be a smarter and more financially-conscious decision to cut your losses. Consumer Reports recommends, as a general rule of thumb, that you should completely replace any product when repairing it would cost more than half the price of a brand new version.

Overall Efficiency

Old air conditioning systems can be kept in perfect working order right up until they’ve served their 10 to 12 years. Constant maintenance and repairs could keep a unit running at full-strength for its entire lifespan or longer. However, newer replacement systems are inherently more efficient. Increases in efficiency mean your air conditioning uses less energy to cool the same amount of space, saving you money on utility bills for the entire life of the system. Some states even offer federal tax credits to homeowners who invest in high-efficiency systems, making them even more cost-effective.

Environmental Impact

If you’re concerned about your home’s energy expenditure and carbon footprint, a complete system replacement is likely the best option. The average heating and cooling systems uses up to 50 percent of your home’s total energy costs. Replacing your current model with an ENERGY STAR® qualified unit could help increase your energy efficiency and drastically decrease your monthly utility bills. A simple repair of an older system wouldn’t be able to provide the same return.

With Houston’s infamous heat and humidity, it’s no surprise that most people prefer to spend their time indoors. Although it may seem more comfortable, the air inside your home might actually be worse for you than the air outside. The same humidity that drives you indoors can compromise your home’s health and comfort, encouraging the growth of mold and mildew that further diminish your indoor air quality. Here are a few methods to help you manage indoor humidity and ensure your air stays clean and sanitized.

Dangers of Excess Moisture

All air, whether inside or out, naturally contains some water vapor. Warm air can hold more water than cold air so as the temperature rises, so does the chance of humidity. Very moist air can make people feel chilled in cold weather while also being the cause of “stickiness” in hot weather.

In addition to affecting your comfort, overly damp air can negatively impact your health. High moisture is directly related to an increase in the growth of mold and bacteria, which then release spores into the air. These spores reduce your indoor air quality and can cause respiratory problems such as asthma attacks.

Simple Steps You Can Take

Some of the easiest ways to decrease indoor humidity are by properly ventilating your home and stopping the accumulation of moisture at its source. By opening windows on opposite sides of the house, you encourage passive airflow that will prevent moisture from settling inside. An effective air conditioning system will have the same result.

Household activities such as cooking, washing and even breathing are the biggest sources of indoor moisture. Always be sure to use your hood fan or bathroom exhaust fan to prevent the buildup of water while preparing food, bathing or showering. If you still notice high levels of moisture, consider investing in a small dehumidifier for problematic rooms.

In certain climates, such as Houston, fighting indoor humidity often feels like a losing battle, even if you follow all the best practices outlined above. Purchasing separate dehumidification systems isn’t the only option thanks to companies like Lennox who have developed technology such as the Humiditrol® dehumidification system. You can now order the latest high-efficiency, high-SEER rating equipment with this dehumidification technology built in so you can enjoy exceptional heating and cooling performance with the added benefit of optimal humidity control options.

Reducing Air Pollution

For the most effective humidity and air quality control, you’ll need professional help. An air quality technician can help reduce indoor humidity by adjusting your heating, ventilation and air conditioning system, but also has access to more heavy-duty options for keeping your air clean.

Professionals can install whole-house air filtration systems to remove particulate matter, such as mold and mildew spores, with HEPA quality filters. Germicidal ultraviolet lamps can also be installed in your home’s air ducts to kill bacteria and other contaminants on contact, ensuring the harmful particulates stay out of your home and lungs.

Another cutting-edge option is the Air Scrubber Plus® with ActivePure™ technology, which utilizes technology originally developed in coordination with NASA to develop a system for recycling and cleaning air in the International Space Station. The Air Scrubber makes your home safer and more livable, and can even make your routine cleaning duties easier thanks to its ability to “scrub” the air circulating through your HVAC system with a specially designed germicidal UV light. The technology can remove all types of indoor air pollutants, including cigarette smoke, bacteria, pet and cooking odors, mold, pollen and more.
