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.

3 Tips to Fix Pressure Balance Problems in Heating and Cooling

Tuesday, January 13th, 2015

Did you know…the air in your home can be a negative, positive, or neutral pressure? It’s true and it’s one of the least understood – and most important – issues in heating and cooling. Ideally you want a neutral system, but finding the balance of negative and positive pressure can be challenging and can create different zones of heat and cold throughout your home.


Whether it’s positive or negative, too much pressure is not good for your home. Neutral air is the most energy efficient because it means there is no air escaping through cracks or unsealed ductwork and outside air isn’t entering the home. The best pressure in your home is neutral to slightly positive as it is also the most comfortable while preventing dust, pollen, and other contaminants from entering the home.

What’s negative pressure?

When too much air is drawn into your home, it creates a condition known as negative pressure. Dust, pollen, and environmental contaminants enter your home and can cause allergies, asthma, and health risks associated with dust, mold, and carbon monoxide. Some of these issues can be resolved by properly sizing and sealing ductwork, and installing weather stripping on doors and windows.

What’s positive pressure?

When conditioned air within your home is escaping through windows, doors, and cracks into the attic and elsewhere, positive pressure is created in your home. The system just heated or cooled the air and that conditioned air is flowing right out the door – literally. It costs you in increased utility bills.

An energy audit will determine if your home has a positive or negative air pressure, as well as the cause(s), and solution(s) to get your home to neutral pressure.

Just Call John’s to schedule an energy audit and learn about the pressure in your home today.

3 Tips to Size and Seal Your Duct System Properly

Thursday, October 23rd, 2014

While the actual HVAC unit is important to keeping your home comfortable during the hottest and coldest months of the year, the duct system plays a key role in keeping you comfortable and healthy. If it isn’t sized properly, it can cause dust and contaminants to enter your home, hot air to be brought into your home through the A/C system, and increased energy bills.

Do you need to size and seal your duct system properly?

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.

Test the System. The team at John’s Refrigeration can evaluate and renovate the duct system of your home, solving these problems:

  1. Size Matters. Your home breathes just as we breathe. When the ducts are too small for the HVAC system that is installed, it causes the air to be constricted and the system to work harder to heat and cool your home. We will examine every part of the duct system for leaks, blockages, and poor design.

TIP: Use the proper size air filter for your system and change the filter as directed; typically once a month. Improperly sized or dirty filters constrict the flow of air as much as an improperly sized duct system.

  1. Air Quality Matters. The key to healthy indoor air quality is having a certain amount of fresh air in the home. We can test indoor air quality and fix issues you may have, including helping fresh air flow properly through the system and into individual rooms.
  2. Hole-y Matters. In the typical home, about 20% of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. Leaks cause the system to work inefficiently, costing you in utility bills. We can repair the leaks and fix breaks and get your money back in your pocket.

The team at John’s Refrigeration can size and seal your duct system properly, keeping air flowing, contaminants and dust outside the home, and you comfortable. Schedule an appointment today!

The Benefits of Going Ductless

Monday, September 29th, 2014

If your home does not have any ducts currently installed, or if you’ve recently added a new room extension onto your ducted home, it can be difficult to find the best way to keep cool. Fans cannot actually cool a home, and portable air conditioners just don’t do the trick. Adding on ducts can be very difficult in some structures, and it takes up a lot of time and energy. But if you ask any HVAC expert about the best way to cool an entire house or room without installing ducts, they’re likely to tell you about ductless cooling.

Ductless air conditioning involves the installation of an outdoor and indoor unit, much like central air conditioners. But while central air conditioning uses a fan to distribute air through the ducts, ductless systems instead contain all of the indoor components in an air handler mounted high on the wall or ceiling. These air handlers blow cool air directly into the room, which is why most homes require multiple air handlers. However, one outdoor condenser unit can usually accommodate up to 4 indoor air handlers.

Here’s why this may be the best option for you:

  • Comfort: A ductless unit provides even cooling throughout the entire home without the need for ductwork installation. Ductless units are generally just as powerful as central AC systems. In fact, many ducted systems cannot perform as well due to leaks that commonly occur in the ducts. With a ductless unit, you won’t have to worry about air leaks, which means greater comfort and energy savings.
  • More Control: When you use ductless air conditioning to cool your entire home, you get the added benefit of zone control. Each air handler has its own thermostat, which means that you get to choose to set the temperature in any zone of the house separately from the other areas.
  • Energy Savings: Central air conditioners risk the problem of standby energy loss due to leaky ducts. Often, homeowners are paying extra to cool unoccupied spaces such as the attic or crawlspace. Ductless units eliminate this potential energy loss, and usually have very high efficiency ratings.

To schedule the installation of ductless air conditioning in Mesa, AZ, call on the experts at Johns Refrigeration today!

How does air conditioning work?

Thursday, September 25th, 2014

At John’s Refrigeration, we spend a lot of time learning how to keep our customers comfortable at home, especially during the extreme summer temperatures.

You might take the cool indoors for granted…until it breaks…and then you might wonder: how does air conditioning work? (more…)

Improper Voltage and Air Conditioning Repair

Friday, September 19th, 2014

Your air conditioner needs a good amount of electricity to operate – this is why it likely has its own circuit breaker in your electrical box. Problems with voltage can affect your whole system, because the system itself and various parts and components all need a specific amount of electricity in order to operate properly. Working with electricity requires training and expertise, so it is not advisable to try and repair electrical problems with your AC on your own. Instead, call the people you can trust for air conditioning repair in Mesa, AZ: John’s Refrigeration.

How Problems with Improper Voltage Can Occur

There are a few ways improper voltage can occur in your system:

  • Faulty wiring – it’s not unusual for the wiring in your system to fray or corrode with use. When wires breakdown, their connection can become faulty, which can result in uneven electrical flow.
  • Failing capacitors – your air conditioner runs on alternating current (AC). This kind of current comes in varying voltages, so in order to smooth out the voltages and deliver an even flow of electricity to the motors in your system, start and run capacitors are used. Start capacitors store electricity and provide the boost of energy (torque) the motors need to start; the run capacitor smooths out the electrical current and flows it to the motors at 1.5 times its normal current. If the capacitors malfunction or fail, the voltage regulation can be interrupted.
  • Issues with the breaker – as we mentioned above, your air conditioner most likely has its own breaker in your electrical box to help manage the amount of electricity it draws. Sometimes the breaker can be faulty and cause the circuit to trip (turn off). A breaker can also be too small to handle the electrical load needed by your AC, which can also cause it to trip. In either case, the voltage isn’t being handled correctly, and the breaker will most likely need replacing.

As tempting as it may be, it is never a good idea to try and repair your air conditioner’s electrical problems on your own; you can put yourself and your system at risk. John’s Refrigeration is here to help with all your air conditioning repair needs in Mesa, AZ, and we are available 24 hours a day, 7 days a week. Having electrical problems? Call us today!

3 Common Heat Pump Repairs

Friday, September 12th, 2014

Heat pumps are ingenious devices, providing both heating and cooling to your home. But like any other heating and/or cooling device, your heat pump will need repair at some point. Our cooling season is much longer than other parts of the country, so it’s not an option to be without AC. This is why it’s important to make air conditioning repairs quickly, and with a company you can trust – like John’s Refrigeration.

Common Heat Pump Repairs

There are some common heat pump repairs that our technicians see with relative frequency:

  • Reversing valve gets stuck – the reversing valve on your heat pump is the component that allows it to switch between heating and cooling. However, this switch can get stuck in a single mode (cooling or heating) or in between. Sometimes repairs can fix problem, but many times the valve will need replacement.
  • Bad solenoid – each reversing valve has a low-voltage electrical component called a solenoid, which helps move the heat pump setting from one position to the other. The solenoid has two wires that can fray, corrode or disconnect, causing the solenoid to malfunction. Solenoids can be replaced, so typically you don’t need to replace the entire valve when experiencing a solenoid issue.
  • Refrigerant leaks – refrigerant leaks can occur in multiple areas of your heat pump system; however, if there is a refrigerant leak inside your reversing valve, the valve will need replacement. Refrigerant leaks can be challenging to locate, and certification is required when handling refrigerant, so it’s important to call a professional for any kind of refrigerant leak issue with your heat pump.

Maintenance Helps Prevent Repairs

Maintenance is a great weapon when it comes to preventing repairs with your heat pump. Why? Your heat pump is thoroughly inspected, including the electrical components, refrigerant levels, the reversing valve, the heat pump controls and the air filter. Components will be adjusted, cleaned and lubricated as needed, allowing your heat pump to run optimally.

Heat pumps can offer your home both heating and cooling, and they can last a long time – but not without proper care. If your heat pump is giving you problems, call the people you can trust for air conditioning repair service in Mesa: John’s Refrigeration.

Ways to Reduce the Strain on Your Air Conditioner

Friday, September 5th, 2014

If you’ve ever had to schedule air conditioning repair for a broken down AC on a hot day, it’s probably an experience you don’t want to repeat. Our air conditioners run for long periods of time here in Mesa, AZ, so it’s not surprising that they may need repairs from time to time. But isn’t there something you can do to prevent problems from occurring in the first place? Here are some of the ways to reduce the strain on your AC, thus decreasing repairs and lowering your energy bills.

Clean Your Air Filters

One of the best ways to keep your air conditioner working its best is by cleaning the air filter about once a month. The air filter is responsible for helping with the indoor air quality by filtering pollutants before they reach your home. But if it becomes too clogged, your AC struggles to work properly, and components may freeze.

Visually Inspect Your Unit

Keep an eye out for anything that may put some extra strain on your air conditioner. Clear any debris away from the outside unit and make sure the vents indoors are not blocked. Listen for unusual noises, and keep an eye out for ice on the coil, thermostat trouble, or high energy bills. Call a technician at the first sign of problems.

Program Your Thermostat

Instead of keeping your air conditioner running all day, use the programmable thermostat to set your AC to a comfortable temperature while you are home and a higher temperature while you’re away. You can even set your unit to adjust to your preferences 30 minutes before you come home, so you’re greeted by a cool house. If you do not already own a programmable thermostat, call an air conditioning technician for installation.

Schedule Regular Maintenance

Just as you should regularly service your car, your air conditioner needs regular attention as well. When you call for air conditioning maintenance, a technician will inspect and clean various components of your system. This is useful because dirty coils often lead to repairs and inefficiency, as do other issues found during maintenance, such as a clogged condensate drain.
