Indoor Air Quality Testing and Your HVAC

August 15th, 2013

Have you heard of indoor air quality testing? The EPA ranks indoor air pollution the fourth largest environmental threat to our country. And, according to a study by the Commonwealth of Massachusetts, indoor air contaminants are responsible for half of all illnesses.

In approximately 500 indoor air quality investigations in the last decade, the National Institute for Occupational Safety and Health (NIOSH) found that the largest source of indoor air quality problems, at 52%, is inadequate ventilation.

Heating and cooling issues, mold, secondhand smoke, volatile organic compounds (VOCs are often found in paints and common cleansers), viruses, pollen, animal dander, water leaks, and particles from dust mites and cockroaches, can cause indoor air quality problems and trigger health concerns.

 

Poor indoor air quality can cause or contribute to the development of infections, lung cancer, and asthma. It can also cause headaches; eye, nose, throat, and respiratory irritation, coughing, difficulty concentrating, sensitivity to odors, muscle pain, and fatigue.

The American Lung Association recommends source control as the first line of defense against indoor air pollution. Appropriate ventilation with clean, fresh air can also reduce levels of indoor air pollutants. Newer, more energy-efficient homes don’t always breathe properly and are sometimes more polluted than older homes, so there are different concerns to consider depending on the age of your home.

A clean HVAC system is crucial to your family’s health and air quality. John’s Refrigeration Heating and Cooling tests your home and the duct system to identify areas where the contaminants are getting in and will recommend actions you can take to keep the air inside your house as safe as possible.

We can determine how clean or dirty the air inside your home is and offer suggestions on how to improve its quality. We can install an electrostatic air filter, an Advanced Oxidation Air Purifier, or either aHumidification or De-humidification System. You will breathe easier once John’s identifies the air quality problems inside your home and resolves them.

Air Conditioning Appreciation Week

August 12th, 2013

 

In honor of Air Conditioning Appreciation Week (which should be a public holiday in Mesa, AZ!) John’s Refrigeration Heating and Cooling would like to point out a few cool facts about air conditioning and why we should be grateful for a/c:

  • The first air conditioner was invented by Willis Carrier for a publishing company in 1902 in order to keep temperature and humidity low so that the paper did not expand and contract. A/C also helped ink to dry faster and smudge free.
  • The term “air conditioning” came from a North Carolina textile manufacturer in 1906 because the technology actually improved the quality and condition of the cloth being made in his plant.
  • During the Depression, movie theatres were one of the few buildings that had air conditioning, making them the coolest places in town. People would flock to theatres just so they could enjoy the cooled air. This is why movie studios started releasing their most lavish productions in the summer, creating the tradition of the summer blockbuster.
  • Before air conditioning, many businesses and industries used to slow down or even stop during the summer because the buildings were just too hot, affecting production. American workers used to get a month-long vacation in August due to these breaks and some European businesses continue this practice.
  • Air conditioning actually helps us live longer, since the cool, controllable environments in laboratories and hospitals have allowed us to create medicines that conquer malaria, inhibit bacteria, and advance developments in surgery.

Have John’s service your system at the beginning and end of each cooling season to ensure efficiency because if you treat your air conditioning unit well, it will continue to give you comfort. We want your family to be cool and comfortable all summer long and our Indoor Comfort Specialists will take the heat out of your summer.

Reasons to Renovate a Duct System: Heating and Air Conditioning Repair

August 9th, 2013

The efficiency of the HVAC system of your home is dependent on many factors including the duct system. A properly sized and sealed duct system eliminates dust and contaminants as well as hot air from being brought into your home through the air conditioning system. Air conditioning repair isn’t just about the A/C unit. The team at John’s Refrigeration can help you cut as much as 20% from your heating and cooling related energy costs by testing and repairing the duct system of your home.

Did you know?

  • As little as 70% of the work the HVAC unit does actually ends up in your home. This is due in large part to the duct system being inefficient.
  • As much as 20% of the air that moves through the duct system is lost due to leaks or improper installation.
  • Our high quality and experienced home comfort specialists are authorized by SRP and APS for duct testing and repair.
  • You may be eligible for SRP and APS rebates for duct testing and repair services.

 

 

Your home may have ducts that are not properly installed if you experience:

  • Extremely high energy bills during the hottest or coldest months
  • Rooms that are stuffy or difficult to keep cool or warm
  • Excessive dust and unpleasant odors

What creates the inefficiency? The duct system is basically like the veins in your body. It carries the air from inside, through the HVAC system and back into your home. If the ducts are not sized properly, or the wrong filter is used, it creates high pressure in the HVAC system similar to high blood pressure in your body when your veins aren’t functioning properly. This makes the HVAC system work harder costing you more money.

Renovating the duct system helps the system run efficiently costing you less money.

Typically HVAC units are placed in the attic of the home. The system pulls air from the house, through the system and back into the home. In the summer the air pushed back into the home is cool and in the winter is warm. An efficient HVAC system will take all the air from the home and return the equal amount of air back into the home and will maintain a season-appropriate temperature

A proper duct system is sized, sealed and insulated properly. Having the duct system sized wrong can create high blood pressure in the system. Many times the duct system is sized wrong but it still working because of leaks. This is why we pay attention to both the sizing and the sealing of the system.

At John’s Refrigeration we want to create a healthy and efficient home environment for you and your family. Contact us today to learn more about testing and repairing the duct system of your home and applying for rebates from APS or SRP.

John’s Refrigeration of Mesa, AZ Wins Quality Home Comfort Award

August 2nd, 2013

Annual award recognizes excellence in residential heating and cooling projects

 

Keeping homeowners in and around Mesa is what the team at John’s Refrigeration does best, and has been doing since 1970, when Chris John started the company. The company recently received national attention, when it was recognized with a Quality Home Comfort Award from ContractingBusiness.commagazine, a leading, national HVAC industry publication.

The Quality Home Comfort Award is given to residential heating, ventilation, and air conditioning contractors based on details and photographs of comfort system installation projects provided to the magazine’s editors, based in Cleveland, OH.

The winning project was completed at the home of Bill and Aimee Edwards. The Edwards family was unhappy with uneven temperatures throughout the home, high utility bills, and dust problems.

“Even though they were new to the home, they noticed these issues right away,” says Andrew John, owner of John’s Refrigeration, who runs the company with his brother, Stephen John.

The team also discovered other comfort problems, such as duct leakage, low return air levels, and major pathways from the attic in the return air plenums. Providing the homeowners with superior energy efficiency was a top priority for the team at John’s Refrigeration.

“Every part of this project paid attention to efficiency,” Andrew John says. “Sealing the attic paths, sealing the duct system, installing proper plenums and dampers, and adding more return air.”  He adds that the Edwards were easily spending 20 to 30% more on utility bills just from the fact that almost all of the unit’s return air was coming from the hot attic.

The team installed two high-efficiency Lennox units and a Lennox iComfort touch screen thermostat. Additionally, dampers were installed on all of the supply ducts running off of the units so that the system could be fine-tuned over time according to the homeowners’ comfort needs.

Tips for the Right Thermostat for Heating and Cooling Your Home

August 2nd, 2013

If you’re a do it yourself homeowner, you may have bought and installed your own thermostat for heating and cooling. Did you know? Thermostats you purchase at the big box stores are not the same quality and grade we use for our customers.

As an HVAC contractor we are able to purchase contractor grade thermostats that generally have a five year warranty and are higher quality. This isn’t to say the box store thermostat you bought isn’t good for your home. There are plenty of great options.

 

Here are tips for selection and installation of the right thermostat for your home:

  1. Type of HVAC System: The type of thermostat depends on the type of system you have at your home. The most common are heat pump or gas heat. Some thermostats are universal so it important to check the box before purchasing.
  2. Programmable: Most people choose a programmable thermostat to help manage energy costs. Cool the home when rates are off-peak to save money. There are now thermostats that can be accessed through an app. You can turn the fan on and off and manage the temperature of your home right from your cell phone!
  3. Installation: This may surprise you – We recommend* not looking at the installation instructions for wiring. Simply take a picture of the old thermostat and install the new one the same way. Remember to turn off the air handler before beginning uninstall and re-install.

*If the new thermostat has a C terminal and the old one did not, you need to call us for assistance. Please turn off the breaker to the air handler. If the unit is on the roof, please turn off the entire unit before starting any installation and especially of the old thermostat had a C terminal.

At John’s Refrigeration we want you to feel comfortable breathing clean air in your home. Should you have questions about your HVAC unit or the thermostat installation, please do not hesitate to give us a call!

HVAC Systems are Less Efficient than You Think

July 30th, 2013

At John’s Refrigeration we pride ourselves on outstanding customer service, in addition to heating and air conditioning service. Whether you’re selecting a new air filter or a new HVAC system, we are here to guide you through the process. When it comes to selecting a new HVAC unit, we want our customers to choose a product that is best for them, their home and family.

The reality is that HVAC systems are less efficient than you think.

What is a SEER Rating? The SEER Rating is the Seasonal Energy Efficiency Ratio. It is the rating of the HVAC unit cooling output during a typical summer divided by the total electric energy output during that same time. The higher the SEER rating is, the more efficient the unit.

Homeowners often use a SEER rating as a benchmark for selecting a new unit. The problem with using this as a benchmark is in understanding how the SEER rating is derived.

A SEER rating is derived in a laboratory setting with a steady temperature of 85 degrees with perfectly installed ductwork including proper duct sizing and no leaks.

This is great except there are no homes with this type of environment. The average operating efficiency is 63% of the rated capacity due in large part to improperly sized ductwork and poor system installations.

 

What can be done to make the HVAC system more efficient? As we discuss in Reasons to Renovate a Duct System, the duct system is key to energy efficiency within the home. As much as 20% of the air that moves through the duct system is lost to leaks and improper installation.

At John’s Refrigeration we understand the value of an efficient HVAC system and can help you create an efficient and clean home environment.

Air Conditioner Filters: How to Choose an Air Filter for Your Home

July 26th, 2013

The dry, dusty Arizona climate makes it especially important to change the air conditioner filters in your home. Indoor air filtration is your first line of defense in achieving good health but is often overlooked. You’ve seen the air filter commercials on television; what the manufacturers don’t tell you is how restrictive some of these filters can be. Restricting air flow makes the system work harder which in turn increases your electric bill.

Resistance and Efficiency: Select a filter that is low resistance and high efficiency. If the filter you use is “sucked” into the space, you are using a filter that has too high a resistance. You’re actually making the system work harder; it’s like it is breathing through a small tube or having an asthma attack – the system has to work hard to cool your home. Less resistance is like breathing without asthma – it is smooth and efficient.

What size do you need? Not all homes or HVAC systems are the same. The proper size filter will help reduce the dust, dirt and other allergens that enter your home through the system. The technicians at John’s Refrigeration can verify whether your current filter is the proper size for the current system and filter selection.

Has your system been serviced recently? At John’s Refrigeration we offer preventative maintenancepackages to help keep your system running efficiently even through the heat of the Arizona summer. We check the HVAC system of your home or business annually making recommendations as we walk through our complete assessment. Regular maintenance means catching issues before they become major repairs.

What is a MERV Rating for an air filter? MERV Ratings measure the ability of an air conditioning filter to remove dust from the air as it passes through the filter. The higher the rating the more particles removed before they reach the air in your home. Ratings range from 1-16. The most common particles are pet dander, dust, smog, viruses, smoke, spores, pollen, bacteria and environmental contaminants such as pesticides. A rating of 5-8 is good for a residence; a rating of 9-12 is better for a residence. Our technicians can verify whether the current filter is the proper size for the current system and filter selection.

Changing the filter: Whichever air filter you choose for your home, it is important to change them regularly, perhaps once a month especially during the high-use, dry, dusty summer. Not cleaning or replacing the air filters causes the system to work harder. The results can be higher utility bills and repair costs.

At John’s Refrigeration, we want you to feel comfortable breathing clean air in your home or business. We recommend the Air Care electrostatic filters Silver Series which are low resistance and 84% efficient.

Ways to Stay Cool in Phoenix

July 24th, 2013

With temperatures still above 100°, the metro Phoenix area continues to experience extreme heat. We’ve all heard the mantra to drink more water, draw the curtains in your home to keep out the sun, and to limit the amount of time spent outdoors in order to not become overwhelmed by the desert heat. But there are other ways to stay cool in Phoenix, too.

 

  • Something as simple as eating smaller meals, or grazing, instead of eating three large meals a day can help keep you cool. The body has to work to digest what we eat, which heats us up. 
  • Placing a bed sheet in a baggie in the freezer an hour or so before bedtime and then sleeping under or on it can help cool your body temperature down, too.
  • Filling a hot water bottle with ice instead and keeping it near your feet while you sleep also helps.
  • Submerging your feet and/or arms into cool or cold water almost instantly cools our core body temperature. Even the occasional ice cube placed on the wrists offers quick relief.

Years ago, before air conditioning became as commonplace as it is now, people placed bowls of ice in front of fans and the air moving across the ice would cool down a small room or anyone who sat in front of it. Hanging a wet sheet in front of a fan – taking care the sheet doesn’t get pulled into the fan’s blades – also works to cool down an area. These tips would be great to use outdoors on a porch during the hot summer months.

The Center for Disease Control and Prevention states “Air-conditioning is the number one protective factor against heat-related illness and death.” Making sure your a/c is running correctly is what John’s Refrigeration Heating and Cooling does. As your home comfort partner, John’s has Certified Service Consultants ready to help keep you and your family cool and safe. But we’ll still remind you to drink water, too.
