Protect Your Heat Pump with Regular Maintenance

Wednesday, January 22nd, 2014

Here in Mesa AZ, heating systems often include heat pumps, which use the same principles as air conditioning systems to both heat and cool your home depending on the weather. Heat pumps work best in climates with warm winters, making the deserts of Arizona an ideal place to use them. As with any appliance, routine maintenance and upkeep can make a big difference in its ability to function effectively. If you’ve just installed such a system, you should know how to protect your heat pump with regular maintenance.

Maintenance isn’t quite the same thing as repair. It’s basically a tune-up session, in which the technician cleans all the interior components, recharges refrigerant, tightens loose fittings and runs the heat pump for 15 minutes or so to look for any larger issues in need of repair.

This serves two very important functions. Firstly, it allows you to get an early jump on any lingering issues that might get worse as time goes on. That helps lower your repair bills by addressing a small problem instead of a big one. It also gives you the luxury of scheduling a repair at your leisure, instead of rushing to fix a problem as quickly as possible because the heat pump has broken down unexpectedly.

Secondly, it improves the overall functioning of your heat pump: allowing it to run more efficiently. By cleaning off the dirt, tightening the screws and similar maintenance issues, it reduces friction on moving parts and keeps components from rattling in their housings. It also stops things like air leaks, and keeps refrigerant gas at optimum levels. All of that means that the heat pump won’t waste any energy, which means you’ll save on your monthly bills.

If you want to protect your heat pump with regular maintenance, the Mesa, AZ heating systems technicians at John’s Refrigeration is here to help. We operate in Mesa, heating systems are a part of our service plan, and we can provide reliable maintenance to keep your heat pump running at its peak. Pick up the phone and give us a call today. You’ll be glad that you did!

Save with SRP’s Duct Test and Repair Rebate

Monday, January 20th, 2014

Does your home have rooms that are too hot in the summer or too cold in the winter? The culprit may be leaky ducts. SRP’s Duct Test and Repair rebate helps you identify where in your home energy may be escaping. 

Approximately 20% of the air that moves through the duct system in many homes is lost because of improper installation. If ductwork becomes loose after time or is jarred during construction or remodeling, leaks can also easily occur, allowing heated or cooled air to escape into your home’s attic, where temperatures can exceed 140 degrees during our fierce, desert summers.

Loose ducts can pull in dusty air from the attic or even from outside, which ends up being the air you breathe inside your home. The ductwork in a home is like the veins of the body, moving the air (blood) throughout the home. Repairing any leaky ducts ensures the air inside your home stays safe and healthy, keeping your family healthy, as well.

An average of 50% of your annual energy bill is spent on running your heating/cooling system. SRP’s current offer gives homeowners up to $75.00 based on the cost of duct testing and up to $175.00 based on the cost of duct repairs. For example, if you were to have a minimum of $400.00 in repairs and testing done, you would qualify for a $250.00 rebate from SRP. The rebate does take 6-8 weeks to receive, but we file all the paperwork for you. John’s offers duct sealing services year round, but using SRP’s rebate can save you money now, so it’s a great time to have your ducts checked out!

John’s is one of the few contractors who hold the required BPI certification to qualify you for the SRP Duct Test and Repair rebate program. Test and all repairs must be completed by April 30, 2014, so call us today at 480-718-1172 to schedule your appointment or to find out if you qualify for the SRP rebate.

Reasons to Schedule an Energy Audit

Tuesday, January 14th, 2014

If you are concerned about the high costs of energy in your home, then you should consider scheduling an energy audit from professionals. An energy audit is a thorough examination of your home to locate places where you are losing energy. Audit technicians inspect your home’s HVAC system, ductwork, insulation, attics, and energy-generating appliances, and then run tests to find leaks and energy inefficiencies. At the conclusion of the audit, your technicians will present you with a detailed report and recommendation for upgrading the various systems in your home to achieve better energy efficiency.

Johns Refrigeration is a Home Performance contractor with the U.S. government’s Energy Star program: our technicians specialize in helping homeowners achieve better whole-home energy efficiency. We can help you improve the efficiency of your cooling and heating system in Mesa, AZ with our services.

Here’s why you should schedule an energy audit

  • Reduce your bills: This is the primary reason people need to have an energy audit. It will result in lowering your power usage and save you money. An energy audit will provide you a detailed report that will show you what steps to take to have a more energy-efficient home. According to the U.S. Department of Energy, you can save around 16% (after accounting for expenses on improvements) each year using the knowledge from your energy audit.
  • Have a more comfortable home: Hand-in-hand with saving energy is improving your comfort level. Energy audits locate where your home is losing heat and what sealing needs to be done: improved insulation, radiant barriers, window films, etc. Not only will this reduce the strain on your HVAC system, but it will make you more comfortable as well.
  • Find repair issues: During an audit, the technicians may discover problems in your home that have remained hidden until then. Perhaps your heater has a malfunction that is making it work inefficiently, or the venting is poor. This will also lead to improved home safety, since it will protect you from possible carbon monoxide leaks and locate radon.

Schedule an energy audit today

It’s often a bit frightening to people to learn about what might be wrong with their home. But the benefits of an energy audit are too great for you to put it off. The recommended upgrades will provide you long-term savings, and you’ll know you’re doing your part for general energy conservation.

Audits require highly trained specialists, which is why you should contact Johns Refrigeration. Energy audits are one of our specialties. Our experts will help you find a path toward better energy-efficiency with your heating and cooling in Mesa, AZ.

Healthcare for your A/C has never been cheaper!

Tuesday, January 14th, 2014

When the temperature inside your home isn’t what you want it to be, you should be able to adjust the thermostat and feel more comfortable within minutes. The last thing you want to happen is to adjust that thermostat and have nothing happen (a “sick” a/c). No one wants to be too hot or too cold, especially here in Mesa.


At John’s, we understand the need to keep your a/c and heating system healthy and in top working order at all times. That is why we created our Peak Performance Club. With an annual maintenance membership, you get peace of mind in the health of your a/c and heating system. Here is what it includes:

Two (2) 51-Point Inspections (up to $259 value) –to identify anything that could shorten the life of the system, cause an excessively high utility bill or compromise your family’s safety.

Clean Indoor and Outdoor Coils ($190 value)* – to maintain proper airflow and prevent harm to compressor valves. To provide maximum cooling to compressor to extend its life and clear debris to allow for proper drainage to prevent rust.

Clear Condensate ($125 value) – To prevent costly water damage and the potential for mold formation.

These services provide a great starting point for keeping your system healthy and in excellent working order. But there are even more benefits to joining the Peak Performance Club! These benefits include:

Priority Service: You receive service first and ahead of non–club members.

Extended Equipment Life: Prolong the amount of time your heating and cooling equipment can continue to operate at peak levels.

Improved Efficiency, Safety and Savings: With periodic operational checks and performance tests, your HVAC system can perform safely and efficiently without demanding more energy. This means you save more money because your heating and cooling equipment is able to work with the greatest efficiency.

Discounts and Extended Warranty on Repairs: In the event your equipment requires repair, you receive special savings on our normal pricing. Plus, the best repair warranty in the industry: three years for Peak Performance Club Members (standard for non–club members is two years)

No Service Fees with Repairs–On–Demand Service: In the event your system requires a repair that you move forward with, the service fee is on us.

Easy Scheduling: You don’t need to remember to call us. We will contact you by e–mail, postcard, or phone letting you know when it’s time to schedule your next inspection.

Proof and Documentation: If you sell your home in the future, you will have proven documentation that your heating and cooling system has received proper maintenance and is in good working condition. Plus, your membership is 100% transferable.

You will have confidence that every time you adjust the thermostat, things will work the way they are supposed to.

What are the Benefits of an Energy Audit?

Friday, January 10th, 2014

An energy audit is a means of gauging the efficiency and heating/cooling retention ability of your home. A trained inspector arrives and analyses your home using a combination of expertise and equipment such as infrared cameras to spot potential shortcomings in your home’s energy retention, and to make suggestions on ways to correct those shortcomings.  Here in Mesa, heating repair services often offer energy audits, helping households respond to our desert climate with sensible energy solutions. What are the benefits of an energy audit? A few general answers can be found below.

  • It can help you plan for an HVAC upgrade. If you’re looking to install a new HVAC system or make new additions to an existing unit, an energy audit is an excellent way to begin your plans. It can tell you places that need improvement and spots that require attention, which can help you prioritize your options and perhaps decide on the type of HVAC system is right for you.
  • It can save you money. You may notice that your energy bills are going up every month, but have no idea how or why that is happening. An energy audit allows you to pinpoint the source of the problem and correct it with confidence, knowing that it will lower the cost of your monthly bills in the bargain.
  • It can improve energy efficiency. By acting on the findings of an energy audit, you can improve your home’s ability to retain a set temperature, reducing overall costs and improving its resale value in the bargain. Hat can save you a great deal of money over time: enough to offset the cost of the audit itself in some cases.

In Mesa, heating repair and energy audit services are provided by John’s Refrigeration. Our Mesa, AZ heating repair technicians know what the benefits of an energy audit are, and can provide a thorough analysis of your heating and cooling needs. If you’re looking to change your existing HVAC system, or just want some ideas on how to improve your home’s energy efficiency, give us a call today. Our staff of trained professionals is standing by to help!

Know the Defrost Cycle on Your Heat Pump

Friday, December 27th, 2013

Now that it’s cold in the evenings and especially the early mornings, many of us are turning on the heat. While Phoenix is known for its stifling desert heat, freezing temperatures are not unheard of. If you do not have gas in your home you most likely have a heat pump heating system. When is gets really cold our heat pumps are designed to go into a defrost cycle. Understanding your heat pump’s defrost cycle will help you know when something is wrong or if it’s running properly. After all, we don’t want to worry about being able to warm those feet before they hit the ground running in the morning.


Because of the colder temperatures outside, the outdoor coil on your heat pump is cold which can cause frost to form on the coil, which then blocks air movement through it. In order to remove the frost, the heat pump first detects the buildup of ice on the outdoor coil, then it essentially puts itself into cooling to make the outdoor coil hot and defrost the ice.

When the heat pump detects the ice has melted, it terminates the defrost mode and starts to heat normally. A heat pump running in defrost cycle will have a few tell-tale signs.  The fan may blow cold air into your home instead of warm. Other signs your heat pump may be in defrost cycle include the fact that the outside unit is humming, but the fan outside is not running. There may also be steam or smoke outside and water is around the unit or on the roof.

If you witness any of these symptoms, simply leave the unit on and let it run for 15-20 minutes. The unit must run in order to complete the defrost cycle. If the symptoms persist after the unit has run for 15-20 minutes, call John’s and we will send out one of our N.A.T.E. Certified Service Consultants to help. We pride ourselves on being your year-round indoor comfort providers.

How Your Thermostat Affects Your Heating

Wednesday, December 18th, 2013

Your heating system (and your air conditioning system too, for that matter) is usually controlled by a thermostat: the little control panel on your wall that helps you regulate the temperature in your home. Thermostats largely employ digital technology, which can let you program specific times for it to turn on and off (among other things). Because your thermostat allows you to control your heat, it can wreak havoc when problems arise with it. Here’s how your thermostat affects your heating.

A thermostat uses a bi-laminated metal strip (a strip composed of two different types of metal) to detect the changes in temperature in the room. Metal expands and contracts with temperature changes, and the two types of metal expand and contract at different rates which can be measured to determine the right omen to turn on the heat. The strip itself is coiled; a temperature adjustment lever sits in the center and a mercury switch sits on the end. When the coil winds to a certain level determined by the lever, it tips the switch and starts the heating process. When the strip unwinds to a certain level, it trips the level back and halts the heating process.

Many thermostats also use a heat anticipator, which shuts the heater off just before the proper temperature is reached. This helps the thermostat be more accurate, since the anticipator allows the remaining hot air in your ducts to reach its location without going over the assigned temperature.

Needless to say, if one of these components is faulty, the entire heating system can be affected. If the thermostat misreads the temperature, it will turn the heater on and off at inappropriate times, while damage to the switch or lever will prevent the heat from turning on or off at all. The bad news is that the thermostat usually needs to be replaced in such circumstances. The good news is that a trained technician can do so fairly quickly, without a lot of fuss and bother. Johns Refrigeration can advise you on how your thermostat affects your heating, and perform repairs or replace the unit with courtesy and professionalism.

How Do I Know If I Need To Replace My Current Heater?

Tuesday, December 10th, 2013

Here in Mesa AZ, heating installation and heating repair primarily hit us in the winter, when desert temperatures drop and air conditioning units get shuttered for the season. Similarly, it can be hard to tell when you need to replace your existing furnace or boiler with a new one. There are subtle (and some not so subtle) signs that can alert you to the issue if you look for them. “How do I know if I need to replace my current heater?” you ask. A few of the most common signs are outlined below.

  • Your existing heater is old. His isn’t a make-or-break proposition, especially if you’ve given your heater lots of care and maintenance over the years. A well-kept heater can last for months or even years after its “expiration date.” However, if you spot some of the other signs on this list and your heater is more than 10 years old, you should probably think about replacement.
  • Higher bills. This can include bother more extensive repair bills and a higher cost of operation from month to month. As heaters get older, the wear and tear means a lack of efficiency. Replacing your heater with a new one – preferably one with a high AFUE (Annual Fuel Utilization Efficiency) rating can save you a great deal of money on these costs.
  • Recurring problems. Recurring issues such as a lack of overall heat and low air flow could signal a heater that is ready to be replaced. If you’re looking at problems that don’t seem to go away, no matter how many times a service technician inspects the heater, replacement may be the best way to save you time and aggravation.

If you’re asking “How do I know if I need to replace my current heater?” then the Mesa heating installation experts at John’s Refrigeration can help. We work in Mesa, AZ, heating installation is one of our specialties, and we can discuss your replacement options with you if your existing heater is no longer doing the job.

Peak Performance Evaluation Home Energy Audit

Wednesday, November 13th, 2013

John’s Refrigeration Heating and Cooling takes a holistic, whole house approach toward optimizing how your home, duct system, A/C system, and insulation work together. We offer a Peak Performance Home Evaluation–a home energy audit–which assesses the whole house as a system, not just the A/C unit and ductwork. This energy audit is designed to provide you with the best solutions to lower utility bills and improve your home environment, including temperature comfort, indoor air quality, and safety.


After John’s has conducted this test on your home, you will have specific recommendations for improving your central air conditioning system efficiency. Ensuring that you have the right size system will help you to enjoy reduced energy bills. We’ll also make sure you have the proper insulation, effective air flow, and no leaks in your ducts – or anywhere else – that could allow cool or warm air to escape into the spaces in your home that don’t need it.

We perform a Duct Efficiency Test where we compare air in vs. air out.  This tells us whether there is duct leakage, how much air the HVAC unit is delivering, and if your home has the proper duct size. We also test the leakage rate of your duct work. If more than 20% of the air moving through the system is leaking into spaces you do not want heated or cooled, we’ll seal them. Then we insulate your ducts to protect them from excessive heat and cold. John’s is authorized by both SRP and APS for duct testing and repair, which means that our customers may quality for rebates which will save you even more money.

The Peak Performance Home Evaluation home energy audit will also tell us where we can install dampers to make sure some rooms aren’t warmer or cooler than others. By optimizing the air flow throughout your air conditioning system with these actions, you are likely to see lower utility bills and be more comfortable in your home.

We’re confident you’ll choose John’s for the best in year-round indoor comfort.

Programmable Thermostats

Tuesday, November 5th, 2013

Most people choose a programmable thermostat over a traditional thermostat to help manage energy costs. These devices save money by helping to cool or heat the home when rates are off-peak or when no one is home. Now there are thermostats that can even be accessed through an app, which means you can manage the temperature of your home right from your cell phone or tablet!


A programmable thermostat is designed to adjust the temperature in your home according to a series of programmed settings that take effect at different times of the day. For example, during the summer, this device may be set to allow the temperature in the house to rise during the workday when no one is home. It may then be set to turn on the air conditioning before you get home, allowing the house to be cool upon your arrival. The reduced cooling required during the day also means you’re saving energy during the peak outdoor temperatures and money when energy costs are highest. According to the Department of Energy, “You can save as much as 10% a year on heating and cooling by simply turning your thermostat back 3-5°F for 8 hours a day from its normal setting.”

During the winter, the programmable thermostat may be set to a cooler temperature while the house is unoccupied during the day and at night after everyone has gone to bed. Just as in the summer with the cooling of the house, the programmable thermostat can be set to raise the temperature prior to your coming home in the evening or waking up in the morning.

The pre-programmed settings that come with this type of thermostat are intended to deliver energy and utility savings without sacrificing comfort. Depending on your family’s schedule, you can notice significant savings in a short period of time by merely adjusting those settings appropriately for your lifestyle. Think of a programmable thermostat as the energy command center of your home; it’s like the brain that tells your HVAC unit how and when to pump air through its ducts.

Using a programmable thermostat in your home is one of the easiest and least expensive ways you can save energy and money. The key to saving is in establishing appropriate settings that automatically reduce heating and cooling in your home when you don’t need as much. Maximize the efficiency of your heating and cooling system by installing this money saving device or allow John’s Refrigeration to install one for you. If John’s installs a programmable thermostat for you, we will program it for you based on your schedule.
