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 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…)

One smart way that home owners are finding for saving money is areversible air conditioner, which cools in the summer and heats in the winter with a heat pump. What is a heat pump? How does a heat pump work? The answers to these questions will help you decide whether a heat pump is right for your home.(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.

How Does a Heat Pump Provide Heat?

Friday, November 14th, 2014

Your current heating system is finally on the fritz. It may have served you well over the years, but if it’s frequently breaking down, does not perform as it once did, and/or costs a lot of money to run, a new system may actually be of benefit to you. New heating systems are built to be far more efficient than they were a decade or two ago, as the U.S. government repeatedly sets new standards for HVAC efficiency. And if you think you may need a new air conditioning system as well, then you may be in luck. One of the most efficient heating systems available on the market today is also extremely effective for cooling.

The term “heat pump” is deceptive as it may sound like this is primarily a heating system. However, this is untrue; “heat pump” simply refers to a type of system that moves heat from one area to another. An air-source heat pump, the most common type of heat pump used in homes today, is actually more closely linked to an air conditioner, as it contains nearly all of the components therein. So how does a heat pump also help with heating?

First, let’s take a look at how a heat pump works for cooling. It contains the same components as an air conditioning system. Most notably, there is an outdoor and an indoor fan, the outside compressor, a condenser coil, and an evaporator coil. Refrigerant runs through the inside and outside portions of the heat pump, starting at the compressor, where it’s pressurized and heated so that it can release heat during condensation at the outside coil. Refrigerant then moves inside, where it evaporates and absorbs heat from the air, only to release this heat outside and continue the cycle.

The one component that differentiates a heat pump from a standard air conditioner is the reversing valve. This allows refrigerant to flow in the opposite direction. Now, refrigerant absorbs heat as it evaporates outside and heat dissipates into your house at the inside coil as refrigerant condenses. So what makes this unit so efficient for heating? Simply put, it takes a lot more energy to create heat, as most heating systems do, than to move it from place to place. Therefore, a heat pump can save you a whole lot of money in the heating season.

How long should my A/C (heat pump) run before it turns off?

Thursday, June 19th, 2014

Many people in the Valley wonder if the amount of time their unit runs is right.  There are a few factors that affect this.  Typically we size a unit to keep the home 75° when its 108 outside.  What this means for run time is that when we start our season – or the days when it’s in the 80-90’s – the unit will cycle more frequently.  As the temperature increases, the unit will run more and when we have our extreme temps – 110° plus – the unit may not cycle off.  As long as the set point is kept, the unit should be operating properly.

 

The type of thermostat also affects run time.  Older stats used a temperature differential of 2°, meaning that if the stat is set on 78°, it will turn on at 80 and off at 76.  New stats use a .5° differential, so they will cycle more than the old ones.

It’s a myth that leaving the heat pump off while you’re away and then turning it back on once you return home uses less energy than leaving the system on when you are gone. Turning the unit off when you are not there allows the house to get too hot, so the unit will continue to run once you return home and turn it back on, which negates any savings and can strain your HVAC unit. A set point of 3-5 degrees higher than normal is sufficient when leaving the house for the day.

If you aren’t sure if your air conditioning unit is running correctly, Just Call John’s.

 

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!
