Causes of Low Air Flow in Your Furnace

Friday, February 28th, 2014

Furnaces are “forced-air” systems: they distribute the heat created in the furnace’s cabinet through ductwork using an air handler. Your furnace’s burners, gas jets, heating elements, and heat exchangers can work perfectly—but without proper airflow, the heat they generate will not reach you. When you discover low airflow coming from your house’s vents, it points toward a possibly serious problem with the furnace.

There are a number of potential causes for a drop in furnace airflow. The list below will give you some diagnostic help discovering what may be causing the problem. However, you will often need experts in heating repair in Gilbert, AZ to learn the reason for the low airflow—and you’ll almost certainly need these professionals to fix the trouble. You can call the skilled technicians at Goettl Good Guys Air Conditioning any time of the day or night for the help you need.

3 Possible Causes of Reduced Airflow From a Furnace

  1. Clogged air filter: The air filter installed in the furnace’s intake prevents debris from entering the cabinet. It needs to be changed once a month during the height of the heating season, or else the filter will become clogged with dust and dirt and begin to choke off the airflow into the furnace. (A clogged filter can cause other trouble as well, so make sure you have it changed on schedule.)
  2. Breaks in the ductwork: The sealed ductwork maintains the pressure of the air as it travels from the furnace to the vents. If breaks or gaps appear in the ducts, they will cause the air to escape and air pressure to drop. This will also allow an infiltration of dust into the ducts and a loss of heat. If you notice a musty odor along with the reduced airflow, then duct breaks are a probable cause. You will need professional duct repair and sealing.
  3. Broken air handler: The air handler of the furnace contains the blower and motors that send the air through the furnace for heat exchange and then into the ventilation system. Damaged or broken motors, bent fan blades, cracked fan belts, and electrical faults can all contribute to an air handler than can’t work at its regular level. The components will need repairs, or the whole air handler may require replacement.

Furnaces Need Professional Repairs

Changing the air filter is something you can take care of on your own, but for any other issues with airflow, you should call professionals to look into the problem and find the best way to remedy it. If changing the filter doesn’t restore your airflow, get on the phone and call Goettl Good Guys Air Conditioning for excellent heating repair in Gilbert, AZ.

How Do Air Cleaners Work?

Wednesday, February 19th, 2014

Low indoor air quality poses a major health threat in the U.S. today, especially since Americans spend approximately 85% of their time indoors. One of the best solutions for improved indoor air quality is to ventilate a house with open windows and doors for a few hours. However, this is not always an option, especially in a city like Scottsdale, which often experiences blistering hot days. Letting this much heat enter your home also puts tremendous strain on your AC.

However, there are methods to improve your indoor air quality with upgrades to your HVAC system. At Goettl Good Guys Air Conditioning, we recommend our customers look into installing air cleaners into their ductwork. These devices filter the air passing from your air conditioner (and heater) to remove the contaminants that may enter it, such as dirt, dust, pollen, dander, bacteria, and residue from construction. There are two main types of air cleaners, and we’ll go over how they work. Call Goettl Good Guys Air Conditioning for more information about air cleaners in Scottsdale, AZ.

Mechanical Filters

The basic air cleaner catches particles in a filter. The most common type of filter is the HEPA filter, which is composed of a mat of randomly arranged fibers, usually made of fiberglass strands between 0.5 and 2.0 microns. These filters do not work like strainers however, where some particles are stopped while others are allowed to flow through. The HEPA filters instead catch even smaller particles, down to 0.3 microns, through a process where particles that pass within one radius of a fiber will adhere to it. Although HEPA filters can stop most physical particles from passing through, they are not effective at stopping gas and odor molecules.

Electronic Filters

The next level up from mechanical filters are the electronic filters, which can catch particles down to 0.1 microns and can affect smoke, gas, and even bacteria that would otherwise escape a mechanical filter. Electronic filters work through static charges. The fibers of an electronic filter generate a strong static charge as air passes through them. This positively charges the particles in the air, and when those particles pass through a layer in the filter with negatively charged fibers, they are drawn toward them and trapped.

Find The Right Filter

Which type of filter should you have installed? It depends on the sort of contaminants in your home (and there’s certainly nothing preventing you from having both installed). Call in an indoor air quality specialist from Goettl Good Guys Air Conditioning to see what sort of air cleaners will provide the most benefit for your home, and then rely on our team to properly install them. Make us your choice for improving your indoor air quality in Scottsdale, AZ with air cleaners.

The Original Valentine’s Day Greeting Cards

Friday, February 14th, 2014

It’s hard to imagine Valentine’s Day without the traditional greeting cards, whether accompanying a gift of flowers and candy, or sent between children in a school room. For commercial greeting card companies, February 14th is as important to them as the December holidays, Easter, and Mother’s Day.

Valentine’s Day as a celebration of romantic love predates printed greeting cards by a few centuries. In fact, the reason that sending romantic greeting cards became popular was because of the most un-romantic thing you can imagine: a reduction in postage rates.

In 1765, Parliament authorized the creation of “Penny Posts” that used a uniform rate of one old penny per letter throughout Great Britain and Ireland. Printers took advantage of the ease with which people could send letters to each other on Valentine’s Day by crafting cards with love poems on them. Many of these verses were collected in 1797 in the book The Young Man’s Valentine Writer, which was a resource for the lover with a romantic soul but not the most confident poetry style.

By the mid-19th-century, the Valentine’s Day greeting card was flourishing across England. Although people still followed a tradition of creating handmade Valentine’s Day cards from lace, ribbons, and flowers, commercially produced cards now overtook them. In 1835, the English post office mailed 60,000 valentines. As production expenses dropped, the English card manufacturers branched out creatively with humorous and sometimes vulgar cards… many of which we would find startlingly familiar in the 21st century. One of the common jokes on these cards was to design them to look like marriage certificates or court summons.

Across the Atlantic, the United States was slower to embrace the popular British custom. It wasn’t until 1847 that a U.S. printer mass-produced greeting cards for Valentine’s Day. Only two years later, American journalists noted how rapidly people in the country had embraced the tradition, turning into a fad that has never died down. The woman who printed the first U.S. Valentine’s Day card, Esther Howland, is today recognized by the Greeting Card Association with the annual “Esther Howland Award for a Greeting Card Visionary.”

The greeting card industry certainly has reason to thank Ms. Howland. Her idea of going into business printing romantic greeting cards, which came to her after she received a traditional English valentine when she was 19 years old, now sells 190 million cards in the U.S. every year. That number doesn’t include the smaller exchange cards used in elementary school classrooms, which would swell the number to 1 billion. (Who receives the most Valentine’s Day cards each year? Teachers!)

Whether you send out Valentine’s Day cards—handmade, store-bought, digital—or not, we at Goettl Good Guys Air Conditioning hope you have a happy February 14th.

Why Heat Pumps Work so Well in Tempe

Wednesday, February 5th, 2014

Heat pumps serve as both heaters and air conditioners combined into a single unit, and can appear either as centralized systems or broken into individual units are part of a ductless mini-split system. They make a popular alternative to more traditional forms of heating such as forced-air furnaces, and because of the way they function, heat pumps in Tempe just make a whole lot of sense. The reasons why have to do with our particular climate, as well as a few related factors. Here’s why heat pumps work so well in Tempe.

The principle behind heat pumps is the same as the principle behind air conditioning. Refrigerant gas moves through a closed loop system that first reduces it to a liquid state (which bleeds heat into the nearby air), then returns it to a gaseous state (which pulls heat from the surrounding air). Regular air conditioners simply vent the hot air and make use of the cold air, but heat pumps allow you to make use of both. It’s an efficient system because it doesn’t actually need to create any heat or coldness itself. It merely facilitates a heat exchange from the shifting states of the refrigerant. That means it uses much less energy than traditional forms of heating, which saves you a great deal of money on monthly costs.

There’s just one catch. When temperatures drop below 40 degrees Fahrenheit, heat pumps lose a lot of their efficiency. Back East, that usually means combining heat pumps with a smaller furnace to create a hybrid heating system. Luckily, Arizona residents only rarely experience temperatures that low, which means that stand-alone heat pumps remain efficient and cost effective throughout the year.

In the end, that’s really the name of the game: providing adequate heat and comfort levels at the lowest possible cost. Our desert heat keeps winters very mild (and summers scorching), which is why heat pumps work so well in Tempe. Goettl Good Guys Air Conditioning can install and repair heat pumps and provide other heating services in Tempe with your complete satisfaction in mind at all times.
