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!

 

Why do I need a ductless pump in Chandler, AZ?

Wednesday, December 30th, 2015

Ductless heat pumps are a great alternative for homes not configured for duct heating systems. These systems don’t use ducts; they are wall-mounted units that provide your home with heating and cooling. These units can be easily replaced, whereas a duct system may be in frequent need of repair. Each unit is connected to an outdoor condensing unit through electrical lines and refrigerant. Our technicians are certified and have the expertise installing ductless heat pumps in Chandler, AZ and throughout the east valley.

Ductless heat pump systems make sense for Arizona homes, because the winter’s mild desert climate does not demand running a heating system as much as those living in colder states. These units save money by only heating specific areas in the home. This type of system can help save up to 50% on electric heating or cooling costs, which is important when our summers can easily tip cooling costs into the $300 range. These systems are becoming more popular with Arizona homeowners due to the numerous benefits:

  • There’s a reduction in energy loss compared to regular duct heating, where some air gets lost in the vents. This doesn’t happen with ductless heating/cooling.
  • With zone control, you can adjust each unit individually to be at the temperature you’d like, saving on electricity bills.
  • Ductless heat pumps are more efficient (even as they age) than duct heating.

Ready to purchase a ductless heat pump, but not sure which size will work for your home? Don’t worry, John’s Refrigeration will assess your property, as well as talk to you about the way you use your home, and help you find the best solution to keep your home at the perfect temperature, be it summer or winter!

Don’t get left in the cold! How to keep your heater in top shape

Wednesday, December 16th, 2015

 

With average low temperatures of around 39° predicted for the month of December in outlying Valley areas, you really don’t want to get left out in the cold! It is essential to keep your heater in top working condition, otherwise you could be looking at the need for a heat pump repair this winter. To prevent needing heat pump repair in Queen Creek AZ, as well as in Gilbert and Tempe, we suggest following this checklist throughout the year to keep your heater in operational shape. Following these steps will help avoid unnecessary worry and stress to you and your heating unit:

  1. Schedule regular maintenance calls

With John’s, you can join the club and save big with our maintenance program. As a member, you are given priority and will receive service ahead of non-members. Our Peak Performance Club extends the life of your equipment and guarantees savings in the long run.

  1. Change filters regularly

It goes without saying, but this simple tasks is often overlooked. If your system is cycling for longer periods of time in the summer and/or winter, make sure to keep track on your calendar every time you change out the filter.

  1. Invest in a programmable thermostat

This will allow you greater control over your air conditioning and heating system. If you are more technically inclined, you may want to look into a Wi-Fi enabled thermostat. These gadgets are the future in home automation and help you set a schedule that works for you and your home.

  1. Clear debris from the outdoor unit

This prevents a buildup of twigs and leaves, and dust from blocking the outdoor unit. It also stops unwanted pests from using these areas as breeding grounds.

  1. Ask for advice

All our staff are certified professionals and happy to advise you on getting the most out of your heating system. Our technicians are extremely knowledgeable, so the next time they stop by for a maintenance checkup, don’t be afraid to ask them any questions or have them address your concerns.

If you are noticing any strange noises and/or smells or the system is lagging, you may want to consider scheduling a service request sooner rather than later. We are your specialists for heat pump repair in Queen Creek, AZ and Valley wide.

How long should my heat pump run?

Wednesday, December 9th, 2015

 

Winter is officially here! The shorter days and longer nights mean our heat pump is probably getting as much use as it did during the summer, especially with the current cold spell we’ve been experiencing in Mesa, AZ. A lot of our customers frequently ask us, “How long should my heat pump run?”

The run time is determined by two things: (1) the set point and (2) the type of thermostat that you have in your home.

The set point

In the summer months, the unit will typically run more and when we have extreme temperatures, it may not even cycle off. We usually size our units to keep the temperature at 75° when it’s 108° outside. As long as the set point remains in place, the unit should operate efficiently.

The type of thermostat

Older thermostats used a temperature gap of 2°, which meant if the thermostat was set to 76°, it would turn on at 78° and off at 74°. The newer thermostats use just a .5° gap and tend to cycle more often than the older models.

If you are traveling this winter, we advise you to keep your heat pump on while you are away. Many homeowners are surprised to learn that you don’t save on utility bills when powering off the system, as the heat pump will need to work twice as hard when you turn it back on. This can be more costly and cause a strain on your HVAC unit. Instead, we recommend a set point of between 3 and 5 degrees higher than normal when you are heading out of town.

If you are also thinking about replacing your thermostat, consider looking into a Wi-Fi enabled option. This will maximize the amount of control you have on your heating system and it’s a cost effective way to save on energy while ensuring your home is at a comfortable, controlled temperature.

If you are unsure about the efficiency of your heat pump, give John’s Refrigeration a call. We’d be happy to answer your questions.

Why Your Heat Pump Won’t Switch Over

Monday, December 7th, 2015

Heat pumps make a lot of sense in Mesa, AZ: able to provide reliable air conditioning in the summer, then switching over to heating mode on those few occasions when the weather starts to get chilly. It saves money and makes the ability to heat your home a lot easier than using an entirely separate system. But what happens when your heat pump won’t switch over from cooling to heating mode? We get calls like that a lot this time of year, when temperatures start to dip, and if you spot the problem, we can be there in a flash to fix it. Here are a few possible reasons why your heat pump won’t switch over. (more…)

Heat Pump vs Furnace: What’s the Difference?

Wednesday, November 18th, 2015

 

In many cases, the decision to install a heat pump or a furnace is largely dependent on whether your house uses natural gas or electricity to heat the home. Although there are a variety of furnace models on the market that offer electric, gas, and propane options. Don’t just huddle under a blanket, stay warm with a heat pump or a furnace.

The furnace is one of the most common heating systems found in homes throughout the U.S. because of its reliability, efficiency, and durability. While the East Valley gets its share of cool days and nights during the winter months when the furnace will be operating, much of the country experiences a more seasonal climate. When it comes to deciding to install a furnace in your home, a number of factors come into play, including local utilities; is your neighborhood within the parameters of a gas line/service area? Other factors include the actual building structure of your home and how it’s configured. It’s important to know the differences and what each system offers so you can ask the right questions in order to help with a smooth installation.

At John’s, our technicians are certified and able to answer your questions every step of the way. We’ll make the initial calculations to help find the right size furnace to effectively heat your home. Once we have established what model to install in your home, we will begin the process. Then, 60 days after an installation is complete, we return for an inspection, as promised in our guarantee.

Heat pumps do an excellent job in more temperate climates, as they provide both heating and cooling in one convenient systemHeat pumps are one of the most efficient HVAC systems on the market, making them an attractive option to many homeowners looking to reduce energy usage and costs. A heat pump uses electricity to heat and cool your home and they are typically found in many homes in Arizona.

Installing or replacing a heat pump in your home is not a small decision. You will live with it for many years, so you want to be certain that it provides an efficient way to heat and cool your home. One of the most common causes of heat pump issues is poor installation. There are many different components involved to ensure the system runs like clockwork. At John’s, we go the extra mile and take a whole-house approach to make sure your heat pump operates efficiently with the ductwork and structure of your home.

It is our responsibility to provide 100 percent customer satisfaction and we proudly carry an A+ rating from the Better Business Bureau, so you know you’re in good hands when you call on John’s. We also offer a money-back guarantee on new installations and replacements. If you aren’t happy with the performance of the system we installed – or the service within the first year – you can call us to remove the unit free of charge.

If you still have questions about the differences of both the furnace and heat pump, contact John’s; we’re here 25 hours a day, 8 days a week and are happy to address any of your heating concerns.

My Heat Pump is Smoking: What Do I Do?

Thursday, November 5th, 2015

 

If you think your heat pump is smoking, it’s probably not! Though it may appear that your heat pump is smoking, what you’re probably seeing is just steam.

To calm your fears that a house fire may be brewing, it helps to familiarize yourself with the “nuts and bolts” of the system. To start, knowing how the equipment works can help you rest easy and won’t have you jumping to call in the local fire department, unless it’s a real emergency!

My Heat Pump is Smoking Steaming

A heat pump defrosts much like your refrigerator. Condensation and cold air can cause the outer casing to develop a thin layer of frost. Fortunately, the heat pump has a defrost feature to keep frost from building up and creating larger problems.

During the defrost cycle, the heat pump warms up to melt off frost, which is then released as steam.Once the cycle is complete, the steam will clear and your heat pump will look normal.

Your heat pump shouldn’t need to defrost very often (especially in a mild Arizona winter). If you’re seeing the heat pump steam often, it might mean something more serious. To be sure, call John’s to schedule a heating inspection.Your heat pump works hard year round, heating and cooling your home. To keep your system working at its best, be sure to:

  • Check and change your air filters monthly. Dirty filters make your system work harder, causing extra wear and tear.
  • Have regular preventative maintenance done by a professional to fix small problems before they become big.

When you take the time to conduct basic care and schedule professional maintenance checks, your heat pump will run more efficiently and you can prevent more costly repairs.

If you have any questions or concerns regarding your heat pump, call John’s to learn more.

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

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.

Why Consider a Heat Pump?

Friday, January 16th, 2015

You may or may not have heard of a heat pump, a relatively new kind of heating system that’s gaining popularity across the country. Even if you have heard of it, you may not know how it works or why it’s worth choosing over a more traditional system. For those of you who are curious about the benefits of a heat pump, you’ve come to the right place. Read on to find out how a heat pump actually works, and what kinds of benefits it can provide.

What is a Heat Pump?

A heat pump is a non-combustion based system. That is, it does not burn fuel in order to create heat. Instead, a heat pump moves preexisting heat from a space that doesn’t need it to a space that does. It does this by utilizing two different parts of the system, an indoor unit and an outdoor unit. The outdoor unit is installed outside, while the indoor unit is installed inside, as you may have guessed. The two units are connected to each other by power and refrigerant lines.

When the heat is turned on, the outdoor unit evaporates refrigerant using a coil inside its casing. The gaseous refrigerant acts as a heat sink, pulling thermal energy from the surrounding air and into the coil. The thermal energy is then carried down the refrigerant line and into the indoor unit. There, the refrigerant gas is condensed back into a liquid state. This releases the thermal energy to warm the air before circulation.

Benefits

There are multiple benefits to installing a heat pump in your home. The first is that a heat pump system is much more energy efficient than combustion systems. It only has to use electricity to operate, and garners the entirety of its heat from the surrounding environment.

The second benefit of a heat pump is that it can actually act as both an air conditioner and heater. It does this by simply reversing the flow of refrigerant through the system, taking heat from the house and releasing it outside. This saves you the space and expense of installing an entirely new system.

If you’d like to know more about heat pumps, call Johns Refrigeration. We provide heating installation throughout the Phoenix area.
