How important is it to breathe clean air in your home? (As seen on Sonoran Living Live)

February 24th, 2015

Our owner, Andrew John, was recently featured on the TV show, Sonoran Living Live, where he spoke about keeping the air in your home clean.

Did you know the air in your home can be dirtier than the air outside? It’s true and we have a solution.

The whole home air purifier is the solution to cleaning the air in your home.

We don’t always see what’s in the air. Dust, pollen, smoke, pet dander, odors, bacteria, and viruses are in our homes making us feel sick and our homes smell not-so-fresh. Pets, garbage, and cooking odors are among the top smells our customers want eliminated from their homes.

Getting dust, pollen, dirt, and other contaminants out of the air is especially important if you or members of your family have chronic allergies and asthma.

How many air purifiers do I need in my home?

You need as many purifiers as you have A/C units for your home.

How often does the air purifier run?

Ideally, the air purifier runs when the central fan is running in your home. We recommend the air purifier run 24 hours a day, just like the one at Andrew’s house.

How does it work?

There is a catalyst and a light that help kill bacteria and viruses, and they also clean the odors caused by pets and cooking.

How Duct Sealing can Improve Your Quality of Life

February 20th, 2015

When a heating or air conditioning system develops a problem, you usually notice it right away.

Weird sounds start coming from the unit, efficiency decreases, something starts smoking or icing over, etc. etc. Unfortunately, that isn’t the case with ducts. Duct issues are silent, subtle, and often go completely unnoticed by the homeowner. That doesn’t make them trivial, however. Let’s take a look at one of the biggest problems that ducts are afflicted with, and how duct sealing can solve it.

Duct Leaks

Ductwork is really susceptible to leaks, and the sad fact of the matter is there isn’t much to be done to prevent them. Most ducts are installed poorly, leaving gaps between the sections. Even properly installed ducts can work themselves loose through normal operation, expanding and contracting over time. In humid environments, there’s the added problem of moisture causing corrosion and opening holes in the ducts. To make matters worse, even small duct leaks can really add up.

The US Department of Energy has estimated that the average home heating system loses as much as 30% of its output to leaks in the ductwork. Nearly a third of your heating or air conditioning output could be wasted before it gets to its destination, and you very likely wouldn’t even realize that it’s happening.

Duct Sealing

In an effort to address the massive issue that duct leaks present, duct sealing has become a common service. Basically, duct sealing consists of finding and closing any leaks that are present to improve energy efficiency. The HVAC technician conducting the service uses a number of specialized tools to address any possible kind of duct leak. While some homeowners may attempt to seal their own ducts, they often lack the materials and expertise to do the job properly. Duct sealing can also improve your air quality by preventing moisture from entering your ducts and causing mold growth. You should have your ducts sealed at least once every two years, in order to prevent wasted energy.

If you haven’t had your ducts sealed in a while, call Johns Refrigeration. We provide ductwork sealing services throughout Chandler, AZ.

Do you qualify for money-saving SRP rebates?

February 18th, 2015

When you Just Call John’s, you know you’re calling a team that has your best interests in mind. Not only do we want your home a comfortable temperature, we want it to be as energy efficient as possible. That’s why we’ve partnered with SRP as certified technicians in their energy upgrade SRP rebates program.

What is an energy audit?

Our technicians are certified to perform energy audits and make recommendations for energy upgrades that are covered under the SRP rebates on energy upgrades. We will talk to you about your energy efficiency concerns, including:

  • Cold/warm air coming into the home through doors and windows that aren’t properly sealed
  • Insulation that is missing or not properly installed
  • Temperature variance of 2-5 degrees in different rooms of the home

We will then inspect and test your home, including ductwork, attic, crawl space, air conditioning and heating unit, insulation, appliances, and lighting to determine inefficiencies and identify areas where you could be saving money on electricity.

Energy inefficiencies include:

  • Use of lightbulbs that are not energy efficient
  • Non-Energy Star appliances
  • Older HVAC units (these are less energy efficient; see new SEER requirements)
  • Improperly sealed ductwork, windows, and doors
  • Negative pressure and/or lack of fresh air

After the energy audit, our technicians make recommendations for changes to your home. Some of these upgrades may be covered by SRP Energy Upgrade Offers:

  • Air Sealing Rebate – When air isn’t travelling efficiently through the system, the air in your home can contain dust, pollen, and other contaminants that are unwanted, especially if you have allergies or asthma.
  • Insulation Rebate – Not only should your home be well insulated, the installation should be properly installed and free of gaps, voids, and compressions.
  • Duct-Sealing Rebate – As much as 20% of the air in the duct system could be lost through leaks if ducts aren’t sized and sealed properly. That means the system is working harder to keep your home a comfortable temperature. The result? Your utility bill is higher than it would be if the ducts were properly sized and sealed.
  • High Efficiency System Rebate – If you’re tired of maintenance on your unit or your unit is tired of working, it could be time to invest in a high efficiency unit. The investment is worth the cost, especially if you get a rebate AND save money on utility bills.
  • Shade Screen Discount – One of the most affordable ways to keep summer sun from heating your home is to have shade screens installed.

If you’re ready to learn how you can save money while making your home more energy efficient, Just Call John’s for an energy audit today!

Lupercalia: The Origin of St. Valentine’s Day

February 14th, 2015

Many people may think of Valentine’s Day as a holiday essentially created by card and gift companies, but the truth is that the holiday has long-standing roots going back to the Roman Empire. The name “Lupercalia” has its origins in the word “lupus”, which means wolf, and the reason for this is that according to Roman pagan religion, the she-wolf Lupa nursed the two orphaned infants Romulus and Remus, the founders of Rome.

The Festival

The Festival of Lupercalia spanned two days each February, from February 13th to 15th. The festival was about fertility and was led by Luperci priests, known as “brothers of the wolf”. The festival was serious with intention (fertility) but was executed as quite a romp for both the priests and citizens of Rome. The process was this: two male goats and a dog were sacrificed at the beginning of the festival by the priests; two young Luperci were then anointed with the blood from the animals, and the hides of the animals were cut into straps. As food and drink flowed, the male priests would run around the city wearing nothing but thongs made from the animal skins, and they also carried a strap from one of the sacrificed animals. The strap was used to strike the palms of Roman women waiting for the priests in the city, as it was believed that being hit with the strap could help with infertility issues and a safe, healthy labor for women who were pregnant.

The Transition to St. Valentine’s Day

The Christian influence of the holiday came around the 5th century. The Roman Empire was still strong, but Christianity was rapidly taking hold throughout the world. It is believed that to try and remove the paganism from the holiday, the deaths of two men, supposedly both named Valentine, were added into the mix. During the 3rd and 4th centuries, a law created by Claudius II forbade young men eligible for military service to marry, because Rome wanted a strong army. The two men named Valentine were priests, and married young couples in secret. Both were found out and executed on February 14th, although in separate years. The Church made Valentine a saint (they chose one), and Lupercalia became St. Valentine’s Day.

Here’s wishing you and your loved ones a Happy Valentine’s Day!

Is Arizona Air Quality Getting any Better?

February 10th, 2015

When it comes to Arizona air quality, the Environmental Protection Agency (EPA) has deemed it improved and within federal standards. The changes were focused in Maricopa County, where about 80% of the state’s population resides. Focus is now moving to Pinal and Yuma counties, where there is still a need to improve air quality.

What happens when air quality is poor?

At John’s Refrigeration, we talk a lot about indoor air quality, but the air outside is just as important. Breathing conditions, including asthma and allergies, are worse when air quality is low. You sneeze more. Your chest feels heavier and you may be getting winded when you’re exercising outside. These are all signs of poor air quality.

What was done to improve Arizona air quality?

Eric Massey, Air Quality Division Director at the Arizona Department of Environmental Quality, said the number one reason improvement happened was partnership of local, state, and national stakeholders, including the EPA. They came together to offer “common solutions to common air quality problems.” [Source]

What were the challenges?

The biggest challenges to improving Arizona air quality were:

  • Best practices that work in other parts of the country weren’t going to work here due to funding and climate.
  • Cost of improvements and compliance monitoring was limited.

For example, in many places, watering the dust is a way to keep air quality at an acceptable level. In Arizona, we don’t have enough water to do this, so officials had to look at other solutions.

Another example is that Arizona doesn’t have funding for the number of air quality inspectors that we need. By creating solutions that were acceptable across a variety of industries and government entities, we created an organically compliant system. Each agency had a stake in improving – and continuing to improve – air quality. That means less inspectors are needed.

What can we do to maintain this level of air quality?

Over the winter, we hear about no-burn days being in effect. These are days designated by the Arizona Department of Environmental Quality and Maricopa Air Quality Department as days when wood-burning fireplaces, chimineas, and other wood burning sources are not to be used. Burning on these days traps particulate matter that aggravates breathing problems and puts young children and the elderly at greater risk.

Complying with no-burn days is a way to directly help your neighbors breathe easier, as well as help the county and state maintain a healthy level of air quality.

Improving air quality in AZ is a team effort of agencies, businesses, and neighbors who have a collective mission to keep air quality at safe and healthy levels.

How Professionals Perform Air Duct Sealing

February 9th, 2015

The wind blowing through your hair can be a great feeling when in a car, but not so much when it’s happening because of faulty ductwork in your home.

The average duct system has a lifespan of about 30 years, but that doesn’t mean it remains in pristine shape the entire time. Ductwork can corrode, become damaged or disconnect at the joints, and all this can add up to serious air loss inside your home. So what can you do to reduce or even eliminate the effects of faulty ductwork? Call Johns Refrigeration and schedule an appointment for duct sealing in your Phoenix home.

What Is Duct Sealing?

First, let’s tell you what duct sealing isn’t: putting a piece of duct tape on your ductwork. Even though it may have the word “duct” in its name, duct tape is not effective for repairing faulty ductwork. What is effective is professional duct sealing. The process for professional duct sealing starts with a full inspection of your duct system so that the technician can assess the areas of damage. Once he/she determines what needs sealing, mastic, a fibrous adhesive, will be applied to the holes and cracks.

A piece of fiberglass or foil tape is placed on top of the mastic, and then the technician moves on to the next problem area so that the mastic can harden into a seal. For sectional disconnections, the technician will apply mastic to both ends of the ductwork, put the ends together and wrap them with metal binding, and then secure the metal binding with sheet metal nails; the mastic will harden and form a seal between the sections.

Benefits of Duct Sealing

  • Increased energy efficiency – air loss from faulty ductwork can account for up to 30% of your home’s total air loss. By sealing the faulty areas, you can regain and even increase the energy efficiency of your HVAC system.
  • Better indoor air quality – not only does air escape from faulty ductwork, contaminants, excess moisture, pollutants and excess dirt and dust do, too. Sealing the problem areas can put an end to these problems and greatly improve your indoor air quality.
  • Better comfort – when your ducts are properly sealed, the correct volume of air is delivered to your living spaces.

If you have faulty ductwork in your Phoenix home, call the experts who can seal your ductwork as needed: Johns Refrigeration.

Heat Pump vs. A Furnace: Which Is Better?

February 3rd, 2015

The answer to the question of “is this heating system better than that one?” and all its variants is always dependent on your individual circumstances.

There is no one objectively perfect heating system, and all of them have to be weighed on their ability to meet your individual needs. With that in mind, let’s take a look at a couple of the most popular heating types: heat pumps and furnaces. We’ll outline the pros and cons of each, in an attempt to help you pick the one that benefits you the best.

Furnaces

Furnaces are the most popular kind of heating systems in the country. They are popular for a number of reasons, including relative cost and availability. Furnaces can come in multiple different types, including natural gas and electric. This makes them able to thrive in pretty much any kind of climate. The most common type of furnace is natural gas burning, mostly because of the high heat output compared to the amount burned.

Though the furnace is the most common type of heating system, it still has its drawbacks. For one thing, furnaces are not the most energy efficient heating systems on the market. For another, they produce several varieties of toxic combustion gases during operation. All modern furnaces are equipped to safely dispose of these combustion gases, but there is always the risk of a malfunction.

Heat Pumps

Heat pumps are fairly new to the market of home heating systems, and are unique in their heating method. Instead of burning fuel, they siphon thermal energy from one area and send it to another. Usually, the heat is harvested from the outside air and then sent inside. Heat pumps are extremely energy efficient, owing to this method of utilizing preexisting heat to warm the home. They are also safer than furnaces, as they don’t produce any combustion gases.

The heat pump’s primary drawback is its vulnerability to extremely cold weather. In areas where the temperature frequently drops below zero degrees Fahrenheit, the heat pump can struggle to get enough thermal energy out of the air to provide adequate heat. If you live in a warmer area, however, that isn’t a problem.

If you still aren’t sure which one would fit your needs the best, call Johns Refrigeration. We provide heating installation services throughout Phoenix.

What are the benefits of whole home humidifiers?

February 3rd, 2015

We have quite a few customers from cooler parts of the nation who look at us funny when we suggest they have whole home humidifiers installed. They wonder why we would want to add humidity to their home; after all, they moved here for the dry, almost-perfect heat. We don’t disagree that the weather in the Gilbert area is close to perfect, but it’s too dry, especially for those of us who may have allergies and asthma.

If you’ve lived where it’s cold in the winter, you know how bad indoor air quality can get. The same is true here in the summer. Our homes are sealed to prevent heat, dust, pollen, and contaminants from coming in, but the air itself is stagnant. Poor indoor air quality can cause breathing problems if not regulated properly. One of the best solutions is to install a whole home humidifier, which will keep humidity levels at a comfortable level.

Benefits of Whole Home Humidifiers

Just as portable humidifiers add moisture to the air, that’s how whole home humidifiers work. The moisture makes harsh, dry summer air easier to breathe and…

  • Creates an environment where viruses are less likely to thrive (Moisture scares them away. They love the dry heat.)
  • Decreases static electricity
  • Prevents dry hair and itchy skin
  • Less likely to suffer dry mucous membranes, which make you more susceptible to colds and respiratory illnesses
  • Less damage to wood floors and furniture
  • Increased energy efficiency

With a regulated level of moisture, it means you don’t need to set your thermostat higher or lower for the same level of comfort. We estimate this can save you as much as 5% on electric bills, while also creating a healthy, comfortable environment for you and your family.

Don’t Wait for a Breakdown Before Scheduling Heating Repair

January 28th, 2015

You listen to that strange sound as your heating system happens, but the heat still turns on – so the system is still ok, right?

Maybe not, and you probably don’t want to wait for a full breakdown on a cold January day to find out. It can be very tempting to refrain from calling for heating repair in Gilbert when your heater is still working, but allowing it to run with a potential problem is a risk. Here are some of the signs it may be time to call an expert from Johns Refrigeration for heating repair help:

Odors

No matter what type of system you have, if you smell an odd odor, it most likely points to a developing problem. Odors to be concerned about would be burning smells, the smell of fuel such as natural gas or oil or burning plastic are all items to be taken seriously. As soon as you smell anything strange coming from your heater, it’s time to call for assistance.

Sounds

There are normal operational sounds for your heater, such as a whoosh at start-up or a click as the thermostat turns on and off. But sounds like buzzing, screeching, ticking or booming are not normal sounds. Should you hear sounds like this, call an expert for repair.

Low Heat

There are a lot of reasons that your system may not produce the amount of heating that you need. Depending on the type of system you have, low heat can be caused by air flow problems, refrigerant leaks, air lock or just plain damage somewhere. Low heat is a strong indication that your system isn’t working at the level it should be, so it’s best to call for a specialist.

More Damage to Your System

Waiting for your system to completely breakdown can cause even more problems as you wait. Problems tend to grow and spread, and if you wait long enough for repair, you may even incur some damage to your system.

If you are seeing or hearing any of the signs of heating problems, call Johns Refrigeration and schedule an appointment for heating repair in Gilbert.

Air Filters and Your Home

January 27th, 2015

John’s Refrigeration is changing the way you think about HVAC and your home. The system to heat and cool your home is really not about the unit outside – or as we like to call it, the box. The system includes the ductwork and air filter, which, when not properly sized and sealed, can cause dust, pollen, and other contaminants to enter your home, making the unit less efficient and you less comfortable.

How do air filters work?

The air that flows through your home goes through a filter before it enters the HVAC system, making it important to have the right size and kind of air filter. When the filter is clogged, the air in your home filters through those contaminants as well, blowing the dust and dirt back into your home.

 

A filter is important, not just to protect you from contaminants in the home, but to also protect your air conditioning and heating unit from damage. The Environmental Protection Agency (EPA) reports changing your home’s air filter as the most important part of maintaining your home and making the HVAC system efficient.

Sizing Air Filters and Ductwork

Filters that aren’t sized properly, including the newest on the market, can actually make your system less efficient by blocking airflow. This causes the entire system to work harder and use more energy. That translates into a higher utility bill for you.

The same holds true when ductwork isn’t sized and sealed properly. Your home breathes just like you do. When it’s not operating efficiently, it’s like it’s having an asthma attack; working harder for the same output.

The role of filtration is to protect the coil, not filter air around the house. In some cases, the solution for an asthmatic system is to use a basic (cheap) blue air filter that keeps the airflow at an efficient rate. Other solutions include having the ductwork evaluated to make sure it is sized and sealed properly so that dust and other contaminants are not entering the home.

Our team wants your home to be energy efficient and for you to feel comfortable. If you’re concerned about the efficiency of your home or aren’t as comfortable as you’d like it to be, Just Call John’s.
