How can You tell when You Need a New Heating Installation?

Monday, March 30th, 2015

After going to all the trouble of selecting and installing a new heating system, no homeowner can be blamed for wanting that system to last as long as possible.

With proper care and maintenance, you can probably get your heater to last a couple of decades or more. No matter how well you take care of it, however, it will eventually reach the end of its life. When that happens, you should be able to recognize the signs. Read on to find out how you can tell when you need a new heating installation.

Repair Costs

Every heating system is going to need repairs at some point during its life. However, you really shouldn’t have to get your heater repaired more than once every year or two. That tends to change once your heating system gets past a certain age, though. As a heating system gets older, the parts that make it up begin to wear out. As each part wears out at a slightly different rate, you can end up with this cascade of part failures that results in your heating system needing repair every few months. If this happens, it’s a pretty good indication that you need an entirely new system.

Cost of Heating Goes Up

You’re going to experience slight fluctuations in your heating bill from month to month as your demand changes. If your heating bills start rising consistently, however, then you may have a problem with your heating system. That same wear and tear that can cause cascade failures in the system also causes the system as a whole to operate less efficiently. As efficiency goes down, the system has to stay operating for longer and longer to achieve the same results. This is why the cost of your heating will go up with an older system.


The general rule with heating systems is that if your heater is older than 15 years, it is time to think about replacing it. Even if the heating system itself is working fine, there are likely much more efficient heating systems on the market that could save you money. If your heating system is younger than 15 years, then you could probably squeeze a few more years out of it before it needs replacing.

If you think you need a new heating system, call Johns Refrigeration. We provide heating installation throughout Gilbert.

Consider a Humidifier to Help with Allergies

Thursday, March 12th, 2015

How Can Humidifiers Help Your Allergies?

Do you suffer from allergies living in Arizona? You’re not alone. The heat and lack of humidity causes dry sinuses and skin, pressure, pain, and bloody noses. Humidifiers can help and here’s how:

What’s humidity?

It’s the amount of moisture in the air. When it rains and the air feels “sticky” or heavy, you’re feeling humidity and it’s needed to keep sinuses moist and functioning in a healthy way. When the air is too dry, you’re more susceptible to getting sick, having bloody noses, and feeling sinus pressure. Using a humidifier, even just one used at night, can help you feel relief from these symptoms.

Types of Humidifiers:

  • Steam vaporizers like the ones you may use when you or your children are sick boil the water into a cold or warm vapor. Vaporizers keep sinuses moist throughout the night to prevent bloody noses and coughing.
  • Impellar humidifiers rotate disks, flinging water into a cool fog.
  • Ultrasonic humidifiers use frequency vibration to create droplets of cool water.
  • Wick systems use a fabric wick to draw water from the reservoir while a fan blows the vapor into the air. These self-regulate depending on the amount of humidity in the air.
  • Whole Home Humidifiers are built into a home’s HVAC unit, keeping humidity at equal levels throughout the home at all times of the day and throughout the year.

In addition to humidifiers, we recommend the following to decrease allergens found in your home:

  • Pollen can aggravate allergies. If you spend a lot of time outside, we recommend taking your clothes off right when you enter the home, rather than tracking pollen, dust, and other contaminants through the house.
  • Take off your shoes at the door. Leaving shoes at the door when you enter means less allergens are brought from the outside and spread throughout your home.
  • Less carpet, more wood and tile flooring. While you might like the soft, warm carpet under your feet, it’s one of the worst things to have in your home, especially if you have allergies or asthma, because it holds dirt, dust, pet dander, and other allergens.

Just Call John’s at 480-718-1172 to learn how we can help you decrease allergens and increase humidity in your home with humidifiers.

Airborne Contaminants and What to Do About Them

Tuesday, March 10th, 2015

As you sit here reading this, you are likely inhaling millions of microscopic particulates. Most of these are harmless, and those that can cause harm are often not in high enough concentrations to be a threat. Under certain conditions, however, these airborne contaminants can lower your quality of life. Let’s take a closer look at what these airborne contaminants are, what they can do to you, and how to get rid of them.

Airborne Contaminants

You’re probably already aware of a few of these contaminants, especially if you have allergies. Dust and pollen are quite common in homes, and cause allergy attacks in many people. Those aren’t the only lung irritants floating around, however. Dust mites, insect dander, pet dander, and mold spores are common as well. All of these can inflame sinuses, as well as cause sneezing and coughing fits. The other contaminants are, unfortunately, even worse.

Viruses and bacteria are present in many homes, as well. The common cold and flu viruses are both communicable through the air, and are the most common illnesses contracted this way. Oftentimes, the airborne germs in your home are too few to penetrate your body’s natural defenses. There are a few exceptions, however. If someone else in your home becomes sick with one of these, the number of viral or bacterial cells in the air will definitely rise. Low humidity in your home can also lower your body’s defenses by drying out the mucus membranes in your sinuses. This makes infection more likely. So, what can be done about these airborne contaminants?

Duct Sealing

The ducts in your home are often a haven for germs and other contaminants, due to their dark and out-of-the-way qualities. These contaminants tend to enter the ducts through leaks and other gaps, then build up in the ducts until a forced air system is turned on. At that point they are circulated throughout the house to infect people.

Duct sealing finds and closes any leaks in the ductwork, preventing contaminants from entering the ducts in large numbers. Duct sealing can also include the application of antiseptic to the inside of the ducts, to kill any harmful germs that may already be present.

If you haven’t had your ducts sealed in a while, call Johns Refrigeration. We provide duct sealing throughout the Scottsdale area.

How Professionals Perform Air Duct Sealing

Monday, 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?

Tuesday, 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 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.

Don’t Wait for a Breakdown Before Scheduling Heating Repair

Wednesday, 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:


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.


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.
