3 Tips to Fresh Indoor Air Quality with Purification or Filtration

Monday, August 19th, 2013


According to the government’s Energy Star program, “Dirt and neglect are the top causes of heating and cooling system inefficiency and failure. To ensure efficient system operation, it’s important to perform routine maintenance.” The most frequent causes of poor airflow include inadequate return duct and return grille sizing, dirty filters and coils, closed registers, and high pressure loss duct designs and installations.

Ensuring these issues are addressed results in a higher efficiency system, a better heated/cooled home, and lower utility bills. More importantly, though, a clean and efficient system results in cleaner indoor air quality within a home. Filtering pollutants keeps you and your family healthier, which also reduces healthcare costs.



Fresh Air

By incorporating a fresh air component into your HVAC system, this will help ensure a steady supply of clean air while working to keep airborne pollutants out. With a fresh air system in place, a certified technician can check to see if an indoor air quality system might also work to your advantage.

Using the correct type of air filter helps keep your system running efficiently while also keeping the air in your home clean. Installing an electrostatic air filter that attracts and holds airborne particles like a magnet keeps the air inside your home fresher by reducing pollen, dust, and airborne pollutants. Since these filters are designed to be reusable, they save you money in the long run, as well. They are easily cleaned by either vacuuming or hosing off the dirt and are far more efficient than any other type of filter on the market.


Cleaning the Unit

Regularly cleaning an electrostatic air filter or changing a traditional, albeit less efficient, filter cuts down on repair costs and results in lower energy bills. But you should also check and inspect the condensate drain in your central air conditioner, furnace, and/or heat pump (when it’s in cooling mode). If the drain is plugged, it can cause water damage in the house, affect indoor humidity levels, and breed bacteria and mold. All of these issues add to air quality problems and will negatively affect your health.

The blower components should also be cleaned and adjusted in order to provide proper airflow through the system. Proper airflow over the indoor coil is necessary for efficient equipment operation and reliability. Maintaining a flow of clean air throughout the home is the optimal goal. With an efficient filtration system in place and a clean unit, your family will be less likely to be exposed to the airborne pollutants that irritate asthma and other respiratory ailments.

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

Friday, 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.

Tips for the Right Thermostat for Heating and Cooling Your Home

Friday, 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

Tuesday, 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.

Six DIY Energy Saving Tips for Homeowners

Monday, July 22nd, 2013

Making your home energy efficient is complicated business. From sealing and insulation to how we live in our home, there are many ways to lose energy efficiency. At Johns Refrigeration we offer a 51-point inspection of the HVAC system including the ductwork of the home. Our Peak Performance Home Evaluation includes air and pressure balancing or pressure checks, an option for incorporating a fresh air component to the system and more. As a homeowner, there also things you can do to make your home more efficient.

Did you know? As much as 80% of energy savings comes from 20% of needed repairs which is why we offer the following six DIY energy saving tips for homeowners:

  1. Sealing around wall or ceiling registers: By sealing the registers you are helping to eliminate dust, dirt, pollen, other contaminants and hot air from entering your home via the attic and air-conditioning system.
  2. Insulating and sealing the attic hatch is a forgotten task for many homeowners. It’s a place where air can be lost or drafts can occur decreasing the efficiency of the HVAC system and increasing energy costs to you.
  3. Install shade screens on the outside of the home. This actually has a greater return on investment (ROI) than replacing windows and doors, at least here in the Arizona desert. The shades prevent the sun from heating the home as much as its non-shaded counterparts. It will take less energy too cool it saving homeowners energy costs.
  4. Stop closing doors. Many homeowners are under the false assumption that closing doors helps save energy when the opposite is actually true. Ideally the entire home should be at a neutral pressure. Closing doors causes a positive or negative environment which causes cool air to escape or brings hot air and contaminants in from outside the home. Keeping the doors open helps keep pressure closer to neutral and your system working more efficiently saving you money.
  5. Programmable thermostats are a great way to regulate energy use and utility cost. Some even have the option of controlling the HVAC system right from your cell phone! Check out our article about selecting and installing the right thermostat for your home.
  6. Choosing the right air filter can not only make your home energy efficient, it will also lower your energy costs. 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 harder to cool your home. Less resistance is like breathing without asthma – it is smooth and efficient. We recommend the Aire Care filters which are low resistance and 84% efficient. Call us to learn more about these filters.
