What’s That Brown Cloud on the Horizon? How to Improve Your Indoor Air Quality

Wednesday, January 13th, 2016

 

Living in the desert, Arizona homes can experience higher levels of dust and other contaminants than homes in other climates. As a result, it’s important to consider your home’s indoor air quality and learn what you can do to ensure a healthy environment for your family.

Those who suffer from allergies can be especially susceptible to issues from poor air quality in the home. Other signs your home may have poor indoor air quality include:

  • Persistent headaches
  • Dizziness
  • Weakness or fatigue
  • Nausea

Many symptoms resulting from issues with indoor air quality appear similar to the flu and often go undiagnosed.

To help improve your indoor air quality, start by contacting John’s Refrigeration to learn about our air quality services. There are a number of simple steps to take to help insure healthier indoor air quality:

  • Check the duct system: Air contaminants like dust, pollen, and other environmental toxins can get into your home and circulate through dirty, leaky ducts. Getting ducts cleaned, checked for leaks, and repaired is a valuable first step for protecting the air you breathe.
  • Install an air filter: After checking and sealing the duct system, John’s can install our Fresh Air Filter System that will help continue to keep the home ventilated with clean air. Air filters catch pollutants before they enter the indoor air.
  • Beware of carbon monoxide: Carbon Monoxide is an odorless but poisonous gas that can come from your heater, furnace, fireplace, or other gas appliances and tools. Undetected, it can cause a number of health issues and can be fatal. When we conduct a heating repair service, we check for things like cracks in the heater, where carbon monoxide can leak.
  • Add a humidifier: Our dry climate leaves the indoor air lacking moisture, causing skin issues, potential respiratory problems, and increased dust. Adding a humidifier to the system can help alleviate these issues and allow homeowners to manage the humidity levels in the home.

To schedule an inspection to check on the quality of your indoor air, contact John’s Refrigeration at (480) 718-1172.

What is an energy audit?

Friday, January 8th, 2016

 

Are you seeing constant spikes in your electricity and/or heating bill? Have you ever questioned the efficiency of your heating system or the working order of your washer and dryer? If you’ve answered yes to both these questions, you should seriously think about having a professional conduct an energy audit in Gilbert AZ or wherever your home is located in the East Valley. The objective of an energy audit is to pinpoint places or parts of your home where you are losing energy.

At John’s Refrigeration, our energy audit process is both unique and comprehensive. The first part of our process is to schedule an appointment with the homeowner to talk about their concerns while asking questions about the home’s current energy efficiency.

After the initial meeting, the technician will inspect the entire property, including the ductwork, attic and/or crawlspace, the air conditioning and heating system, and the lighting and appliances.

Following the inspection, the technician will perform some tests to get reliable readings on the efficiency of the home. These tests show if the home has any energy leaks and helps determine if the home has positive or negative pressure.

Upon completion of the tests, we present the homeowner with our recommendations and provide a plan of action. A variety of issues can be the cause of inefficiencies in the home. Oftentimes we suggest an upgrade of appliances to Energy Star systems, but more times than not it tends to be a heating unitissue and that’s where we dig a little deeper.

John’s Five Step Home Efficiency Program

The box on the roof or exterior wall of your property has no function without proper ventilation; it’s just a box that blows hot or cold air, which is not efficient and offers little in the way of true comfort. If there are any gaps or repair work needed to the heating system, we have the experience and expertise to carry out the job through our five step process:

  1. Size and seal your duct system properly
  2. Fix pressure balance problems
  3. Fresh air & purification or filtration
  4. Balancing
  5. New HVAC equipment

For a full overview on our five step approach please take a look at this video.

Only by addressing all issues (i.e. steps one through five) can we truly help you live in a home that is safe, comfortable, and reliable – one that really works for you!

 

3 Signs of Late Summer Air Conditioning Problems

Monday, August 31st, 2015

We’re at the end of August here in Mesa, AZ. Kids will be heading back to school soon (if they haven’t already) and homeowners will be looking to start fall maintenance. But here in the desert, the hot weather doesn’t stop just because the calendar says it should, and while your air conditioner has already put in months of stalwart work, it’s going to have to keep it up for at least a few weeks more. That’s why it’s important for you to watch for the signs of late summer air conditioning problems. Now is the time when that heavy use may result in significant problems, but with diligence and careful checking, you can spot those problems before they cause any damage. Here are 3 that you should look for. (more…)

Why Can’t You Just Recharge Low Refrigerant Levels?

Monday, August 17th, 2015

Most people know that air conditioners run on refrigerant, a chemical combination that encompasses a number of specific names and formulas. The specific type and amount of gas depends on the make and model of your air conditioner, but all refrigerant has a few things in common: a relatively low vaporization point, an ease of shifting from liquid to gaseous form and back, and the ability to pull heat energy from the nearby air in the process. It’s what makes air conditioning possible, and has proven to be a revolutionary technology in hot cities like Mesa, AZ. (more…)

Air Ducts

Tuesday, July 14th, 2015

Our homes breathe, believe it or not. And our HVAC systems help control that process. How do air ducts figure into this equation, though?

Dirty air ducts cause the HVAC equipment to work harder and less efficiently. Having your ductwork inspected can mean you’ll have improvement in air quality and less dust inside your home. Clean air ducts help the entire HVAC system worked more efficiently. A full cleaning of the air ducts in your home can yield long-term energy savings, but hiring certified professionals to do the job is vital. In fact, a poor cleaning job is worse than no cleaning at all, as it can kick up harmful particles or even break portions of the HVAC system.

Air duct cleaning should involve a thorough cleaning of the air handler, registers, grilles, fans, motors, housings, and coils of the HVAC system, not just the ductwork. John’s NATE Certified technicians will also perform an inspection of the ductwork and let you know if there are any problems that need to be addressed.

If you’re not sure if you need to have your air ducts cleaned or inspected, here are some key questions to ask yourself:

  • Have you renovated your home in the past few years? Ducts should be sealed off during remodeling projects, so if they weren’t, dust and debris may have become lodged inside the ductwork. Or the air ducts could have been moved, causing them to leak airflow.
  • Could there be animals in your air ducts? There may be evidence of animal infestation or nesting in your air ducts or HVAC system, which can greatly affect the air quality in your home. Whether those animals are living in your ductwork or have died, they don’t belong there.
  • Do you see mold on your vents? If there is visible mold growth on your vents or inside the ductwork, the air quality in your home has been compromised and is likely affecting the respiratory health of everyone who breathes the air in your home.
  • Have you noticed pet hair, odors, or dust being released into the room through the vents? Once again, these are signs that your air ducts need to be inspected and possibly cleaned.
  • Does anyone in your family suffer from allergy or other respiratory-related illnesses? If so, you may want to consider having your air ducts cleaned to see if the HVAC system is the reason.

People often report using their air conditioner less in the summer after having their air ducts cleaned because of the improved airflow. That means less money paid to the utility company and more money in your wallet. Plus, your family will be more comfortable and breathe easier. Just Call John’s to see how we can help you with air duct inspections and cleaning.

Three Main Parts of a Cooling System

Thursday, June 18th, 2015

Three Main Parts of a Cooling System

When all the parts of your home’s HVAC system are functioning correctly, the system is more efficient, which uses less power, thereby saving you money on your utility bills. It’s important for homeowners to keep up with regular maintenance on their HVAC systems to keep them functioning optimally. Understanding the parts of the cooling system is important so you know how the whole system works. Here are the three main parts of a cooling system:

  1. The heat exchanger is located in the HVAC unit. Air is sucked into the heat exchanger and then is quickly heated and blown out through the ducts to be circulated through the house.
  2. The evaporator coils are activated every time cool air is needed. The cooled air is picked up by the furnace blower and forced along the ducts and out through the vents. Evaporator coils are connected to the HVAC system’s condensing unit.
  3. The condensing unit is installed outside the home and refrigerant gas is cooled through the exchange of heat with the air outside. Then, it’s compressed and condensed into liquid form and sent through a metal tube to the evaporator coil. Once the liquid reaches the coil, a series of small nozzles spray the liquid, lowering its pressure, causing it to turn back into gas. During the evaporation process, heat is absorbed, which causes a drop in temperature and supplies cold air that will be blown through the home.

Ductwork is important, too, since it carries warmed or cooled air throughout the house to all the rooms in your house, where it exits through vents. Loose ductwork can mean dirty air is being circulated through your home. There are many parts to your heating and cooling system that work together so that you are able to enjoy your home in the temperature you choose. Just Call John’s if you’d like us to take a look at your cooling system to see if it’s running as efficiently as possible.

3 Ways to Ease the Burden on Your Air Conditioner

Monday, June 15th, 2015

Our air conditioners do yeoman work here in Mesa, AZ: keeping our homes cool and comfortable even as the desert temperatures climb into the triple digits. All that work comes with an expectedly high cost, as your air conditioner takes on a big workload and your monthly utility bills spike accordingly. But it doesn’t have to be that way. Beyond common sense techniques to stay cool during the summer, such as hydrating and setting your thermostat a few degrees higher than you normally would, here are 3 ways to ease the burden on your air conditioner, saving you money and reducing the chances of a repair call in the future.(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.
