When Should I Schedule Heating Maintenance?

October 3rd, 2014

Regular heating maintenance is incredibly important for extending the life of your heating unit. There are some times, however, when maintenance is even more beneficial than normal. Let’s take a look at some of the times when you receive the best benefits from heating maintenance.

Preventative Fall Maintenance

The best time to conduct maintenance on any system is right before it is going to be used heavily or over a prolonged period of time. In the case of heating, this means having it serviced during the fall. Most people run their heating system every single day during the winter months, which definitely qualifies as heavy usage. If you time your maintenance to occur just before winter, you can be confident that your heating system is in top condition when you need it most.

You may be tempted to wait until the start of winter itself to get your maintenance done. The reason we do not recommend that is because winter is when heating systems will start breaking down. All the preventable issues that could have been fixed in the fall will cause breakdowns. This will cause a spike in HVAC repair calls. It will generally be far less convenient to secure a service call during the winter. If your heating system breaks down, you could wait several days for a technician while having no heat in your home.

Strange Circumstances

If your heating unit starts making strange noises on startup, turns on and off too frequently, or you notice cold spots in your home, call a professional right away! Small quirks may seem innocuous, but if ignored they could develop into some big problems. You don’t want to leave an obvious malfunction alone until your yearly scheduled maintenance. Fix it right away so you don’t have to deal with your heating unit breaking down.

If you haven’t scheduled your fall maintenance yet, or you are having problems with your heating system, call Johns Refrigeration. We conduct heating maintenance throughout the entire Mesa, AZ area. Don’t wait for your heating unit to break down. Call us today.

Become Part of the John’s Refrigeration Team!

October 2nd, 2014

As a locally owned and operated family business, the team at John’s Refrigeration is always looking for ways to give back to the community and attract talented employees. Our own Andrew John recently appeared on 90.7/92.7 Pulse Radio to talk about his involvement with East Valley Institute of Technology (EVIT) as a member of the HVAC Advisory Committee.

John’s Refrigeration is celebrating 44 years in business. We like to say we’re born in the desert and are built to last. According to Andrew, he has been part of the business since he was old enough to climb a ladder. While that’s not far from the truth, his days in HVAC started as a student at EVIT when it was called Mesa Vo-Tech. Since that time, he has mentored and hired students to work for John’s Refrigeration.

What is it like being a technician for John’s Refrigeration?

Andrew and the team at John’s operate in an ethical and honest manner with all employees and customers: “We pay our employees to be efficient and to do the right thing.”

In other words, you can rest assured you’re not being upsold when you work with our team. Technicians are paid well for providing high quality customer care and staying up to date on training and education. For these reasons, John’s Refrigeration is a great employment opportunity for HVAC professionals.

Our goal is to give our technicians the education and training they need to provide provable solutions to our customers, including:

  • Helping the system operate more efficiently and economically
  • Providing a comfortable and safe environment for you and your family
  • Making the system last a long time

We believe in being comprehensive. While the customer may want all of the solutions today, we want to make sure they have all the information about their HVAC system.

A word about service calls.

While we wish we could provide free service calls, we do have to cover the cost of sending a technician to your house. In cases where the problem may have been misdiagnosed, we do offer a free diagnostic. We will tell you when we get to the point where we understand the problem. While we try to be comprehensive, we understand you may not want to pay for a service call, so we stop our work, providing you with the free diagnostic and estimate.

Why choose the HVAC industry?

There are always jobs in this industry. Andrew says you don’t have to worry about being laid off and can plan ahead for you and your family. Jobs start at $12-15 per hour based on experience and John’s Refrigeration offers opportunity to grow professionally and financially.

Why is Andrew John part of the HVAC Advisory Committee at EVIT?

He believes EVIT does a great job providing kids with a real world education. From this foundation, John’s Refrigeration can help them grow and learn in the HVAC industry. For more information about EVIT and John’s Refrigeration, visit www.justcalljohns.com.

 

The Benefits of Going Ductless

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?

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. I think we can agree that air conditioning is a much needed part of the summer here in Arizona. You might take the cool indoors for granted…until it breaks…and then you might wonder: how does air conditioning work? Continue Reading

Improper Voltage and Air Conditioning Repair

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

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.

Will a new air conditioner improve indoor air quality?

September 11th, 2014

When you ask an Arizona resident what makes them least satisfied, some might say traffic. Others will say all of the chain stores and restaurants. Most of the people we ask tell us they are least satisfied with indoor air quality. This is due in part to the quality of outdoor air, but not completely. Continue Reading

Ways to Reduce the Strain on Your Air Conditioner

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.

If you want to schedule air conditioning maintenance in Mesa, AZ, or if you have any concerns about air conditioning, call Johns Refrigeration today!

Sounds That Can Mean It’s Time for Air Conditioning Repair

September 5th, 2014

One of the easiest ways to tell that it’s time to call an expert for air conditioning repairs is if you hear unusual sounds from your air conditioner. You’re used to the sounds of the compressor starting outside and the familiar humming noise indoors, but anything strange can signal trouble. Don’t ignore the warning signs of a failing system. Even a small repair can cause big problems for other parts of your air conditioner.

Here Are Some Troubling Sounds to Listen for That Indicate It’s Time to Repair Your Air Conditioner

  • Hissing: A hissing noise may indicate a refrigerant leak. Refrigerant is a chemical blend that continuously cycles through your system whenever it is turned on. Refrigerant actually absorbs the heat from your home, which is how the air is cooled. And while the heat dissipates outdoors, the refrigerant will not—unless there is a leak. Without refrigerant, your home may never reach the desired temperature, and other important components of your system may suffer as well.
  • Banging/Clanking: A loud banging or clanking noise can have many different sources. A loose, bent, or otherwise damaged fan blade from the indoor or outdoor fan may bang against the inside of the unit, causing wear and tear to your system and inhibiting the airflow that is necessary for heat exchange. The banging noise may also indicate compressor damage, which requires the immediate attention of an air conditioning technician.
  • Buzzing: A buzzing sound often indicates an electrical problem, such as a problem with the wiring, the motors, or a capacitor. A loose contactor may affect the capacitor, so that the motors in your system do not receive enough electricity to operate properly. You should not attempt to diagnose or fix an electrical issue on your own.

While this list can give you a good indication of what a noise may mean in your air conditioning system, you should allow a professional to pinpoint the problem. Do you need air conditioning repair service in Mesa? The experts at Johns Refrigeration are trained to recognize repair needs and find the source of the problem to get your air conditioner running like normal. Give us a call today!
