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

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.

 

What does being a family heating and cooling business mean to you?

June 17th, 2014

Being a family heating and cooling business means more than just running a business with family members. Simply stated, being a family business means we care about our community and customers as if they were our own friends and family.

At John’s Refrigeration, we are dedicated to providing local customer service. When you call our office during business hours, you will speak directly with a member of our local office. Working with you, they will help get your questions answered and problems solved.

Choose Local When You Can

The ENERGY STAR Program and What It Means for Your AC

June 16th, 2014

You are probably familiar with the ENERGY STAR logo: a white star on a blue background next to the cursive word “energy.” You see it on many types of appliances, from computer monitors to refrigerators… and also on air conditioners. With this label appearing on so many different devices, you may wonder what it has to tell you about your air conditioner. We’ll explain.

For all your concerns and questions regarding air conditioning in Scottsdale, you have a reliable source: Johns Refrigeration. Since 1970 we have served the Valley of the Sun with quality air conditioning and heating services. Trust to our knowledge to keep your AC running year after year.

The U.S. ENERGY STAR Program

The ENERGY STAR label (always written in all-caps) indicates that an appliance meets the requirements of the ENERGY STAR program. The U.S. Environmental Protection Agency initiated this program in the 1990s as a way to help consumers and businesses save money through energy conservation and to help protect the environment.

The ENERGY STAR program sets out requirements for appliances that will make them more energy-efficient and lower their polluting abilities. The program is voluntary: any company can decide if they want to submit their products to the program for qualification.

Each type of appliance has a different set of requirements to meet in order to receive the ENERGY STAR certification. In the case of an air conditioner, a system must have at least 14.5 SEER (seasonal energy efficiency rating) and 12 EER (energy efficiency rating) and contain specific features that consumers demand. The technology used to achieve the high efficiency ratings must not be proprietary: energy-saving performance of this type must be available to all companies.

Do you have an air conditioner with the ENERGY STAR label of approval on it? If you don’t know, check on it right now. For an older air conditioner, it’s possible that it doesn’t meet the program requirements. If your AC isn’t ENERGY STAR approved, you should consider installing a replacement unit that is. Even an older ENERGY STAR-approved air conditioner might not have the efficiency of newer systems (the program’s requirements have changed of the years).

If you want new installation of an ENERGY STAR air conditioning unit in Scottsdale, AZ, contact the experienced team at Johns Refrigeration. We can help you find the ideal energy-saving AC to cool down your home and save you money.

Air Conditioning Repair in Gilbert AZ: Heat wave problems that could have been prevented

June 12th, 2014

With temperatures already reaching over 110, a/c units in need of repair are starting to strain to cool our homes. If there’s another heat wave like we had during 2013, things could get even worse. Before you need to call John’s Refrigeration Heating and Cooling for your air conditioning repairs in Gilbert, AZ this summer, consider preventive maintenance so that you and your family are cool all summer long.

 

In the Southwestern United States in late June/early July last year, seven people died in the Arizona desert from dehydration and exhaustion due to the intense heat when temperatures hit 120°. In fact, it was so hot here that tigers at the Phoenix zoo were served frozen fish treats and butterflies were found collapsed on the pavement due to the high temperatures. Mesquite trees even close their leaves to protect themselves during extended periods of extreme heat, though mesquites are native to the desert.

Keeping you’re a/c unit maintained means you won’t have to worry about it shutting down when temperatures rise to uncomfortable levels. Although it’s great to have a reliable HVAC company like John’s to call when you need a/c repairs or even a new unit, it would be even better if you didn’t need to call them at all and could just not even worry about problems like your air conditioning not working.

If you are not fond of frozen fish treats and you prefer not to collapse on burning pavement, perhaps you should think about calling John’s Refrigeration to make sure your HVAC unit is running at maximum efficiency. Even our name sounds refreshing with temperatures this high.

How to Set Your Air Conditioner During Summer Vacation

June 10th, 2014

Now that temperatures in Mesa, AZ are reaching 110° and higher, some homeowners might be thinking about vacationing in cooler climates…like Alaska. If your family is planning a trip away, or maybe even just a couple of long weekends to escape the desert heat, you might want to think about investing in aprogrammable thermostat.

Using a programmable thermostat in your home is one of the easiest and least expensive actions you can take to save energy and money. A programmable thermostat is designed to adjust the temperature in your home according to the way you use your home. You can set it to cool your home (or warm it in the winter) while you are actually in it – like when you come home at the end of a work day.

You wouldn’t want to turn your air conditioning completely off in the summer, but setting the temperature on your thermostat as high as 85° while you’re away will save both energy and money. Why 85° ? Because many items such as plants, wood floors, furniture, and candles can be ruined at higher temperatures. Your utility bills won’t have to keep rising with the temperatures, especially if you’re not at home.

The purpose of a vacation is to relax and not allow everyday worries to stress us out. Keeping energy costs under control can reduce stress levels the same way that using a programmable thermostat can reduce your utility bills.

There are many ways to save energy and money during the heat of the summer and John’s is available to help you out.

Why Low Refrigerant is a Problem in Your Air Conditioner

June 9th, 2014

Your air conditioner relies on refrigerant to do its job: cycling through various valves and coils, and cooling your air in the process. Refrigerant varies by type and needs to be applied in a set amount unique to your specific model of air conditioner in order to function the way it should. When those levels drop – such as when a leak springs up in the system – it can severely affect your system’s performance. The good news is that services that handle air conditioning in Phoenix usually have a lot of experience in sealing leaks and recharging refrigerant levels.

Here’s A Brief Outline on Why Low Refrigerant Is a Problem in Your Air Conditioner

In simplest terms, the lowered refrigerant levels mean that inadequate amount of refrigerant enter the evaporator coils to complete the cooling process. As a result, frost and ice will form on the surface of the coils, which creates three specific problems:

  1. The ice represents lost cooling potential, stuck inside the air conditioner instead of being blown into your home. The more ice you see, the more cool temperatures are being lost instead of going where they need to.
  2. The ice forms an insulating layer between the coolant inside the coils and the air that needs to get cooled. The more it goes on, the harder the system has to work to cool the air, and the more energy it will use in the process.
  3. Melting. When the ice melts, it could damage other sensitive components in the system. Most AC units have a condensate pan to catch condensation from the coils, but the presence of excess ice could cause an overflow, which is a significant problem.

If you understand why low refrigerant is a problem in your air conditioner, you also understand that you need a pro to fix it. Simply scraping the ice off won’t work (and may damage the coils in the process). Here at John’s Refrigeration, we handle all kinds of problems related to air conditioning in Phoenix, and we know how to properly treat low refrigerant levels. Pick up the phone and give us a call today. You’ll be glad you did!

Tips for Air Conditioning Savings

June 6th, 2014

FUN FACT: The amount of energy the United States uses every year to power our air conditioners is about the same amount of energy consumed by the entire continent of Africa.

With record temperatures approaching in the Valley of the Sun, most people are running their air conditioning units morning, noon, and night. This is the time of year when our utility bills rise higher than the mercury in thermometers. There are ways where air conditioning savings can be incorporated into your busy lifestyle, though, saving you both money and energy.

Here are ten things you can do now to start saving:

  1. Don’t allow the sun’s rays to make it into your home. Keep your windows covered with curtains that block out the heat so the interior of your home stays cool.
  2. Set your thermostat as high as comfortably possible. The smaller the difference between the indoor and outdoor temperatures, the lower your utility bill will be.
  3. Avoid setting your thermostat at an abnormally lower setting when you turn on you’re a/c, as it won’t cool your home any faster and could cause mechanical problems with your HVAC unit.
  4. Turn your ceiling fans on only in rooms where people are present, which creates a wind chill effect, and enjoy up to 4° cooler temps in those spaces. Ceiling fans should be turning counter-clockwise during the hotter months.
  5. Install efficient lighting, like CFLs or LEDs, which run cooler than traditional incandescent light bulbs.
  6. Caulk around windows and use weather stripping around doors to prevent hot air from entering your home.
  7. Turn the temperature of your water heater to 120°, which also helps you avoid being scalded.
  8. Line dry clothes instead of using the dryer after washing them to avoid heating up your home.
  9. Replace a/c filters monthly to optimize efficiency and keep your home cool through the extreme heat of our desert summers.
  10. Have your ductwork checked for leaks, which can account for 25% of cooling costs.

Scheduling regular maintenance for your cooling equipment will also keep your air conditioning system running optimally. John’s can help you keep comfortable all year long by examining your ductwork and checking your whole house for air balancing issues (if you have certain rooms which are warmer or cooler than others). Just Call John’s for all your HVAC needs.

How to Prepare for a New Air Conditioner

June 5th, 2014

If you are planning to have new air conditioning system installation in Mesa, AZ, you won’t have to worry about doing too much work—provided that you’ve hired a professional and experienced heating and cooling company to take care of the actual installation. You need professionals to do this work so that it goes smoothly and leaves you with a system that works properly and problem-free for many years.

There are some steps you can take to prepare for the new AC that will help you receive the most from it. These tasks also require work from professionals, but if you call Johns Refrigeration, we can handle all of them… no need for other contractors! Best of all, we have more than 40 years of experience with installation, so you’ll know that you’re receiving quality work.

Make sure the new AC is properly sized

“Sizing” is the process of finding out how powerful an AC is necessary for a space without wasting energy or short-cycling. An AC that is too large is as much a problem as one that is too small. Experts will perform a heat load calculation to determine how much heat enters a home and how much the appliances and lights inside generate. Once the specialists have determined the heat load, they will know the ideal size air conditioner to install.

Have an energy audit performed

An energy audit determines places where your home is wasting energy. It analyzes the energy-efficiency of the whole house and pinpoints places where energy is lost. The audit will locate the spots where heat enters and escapes, and using this information, the auditors can tell you how you can bolster the insulation. Better insulation means an AC that will need to work less. An audit will help you achieve greater savings with your future air conditioner.

Schedule any necessary duct repairs

An energy audit will also locate spots where there are leaks in your home’s ventilation system. Leaky vents are a major enemy of air conditioners, since they reduce air pressure, cut into airflow, bring heat into the shafts, and can lead to contamination infiltrating the cabinet. Sealing up the duct breaks will make certain that your new air conditioner works at its best.

You can entrust all these tasks to Johns Refrigeration. We will take care of sizing the new AC as a standard part of the installation, and we handle performing audits and duct sealing and repair. Once your air conditioning installation in Chandler, AZ is finished, you can always rely on us for excellent repairs and the necessary maintenance that will keep your new cooling system running for many years.

June 3rd, 2014

School is out for the summer, which means mom and dad are trying to find ways to entertain the kids while staying cool. The Gilbert and Mesa areas bring many opportunities to do just that. From trampoline parks to discounted movies, museums, and aquariums, there’s no shortage of things to do this summer.

 

  1. One of the best places to stay cool in the summer is the movie theater. The Dickinson Free Summer Movie Series is happening in Mesa and Goodyear in June and July on select dates.

  5. For indoor games and rides, check out Amazing Jakes in Mesa.
  6. If bowling and laser tag are more your style, take the kids to FlipSide in Gilbert. They call themselves “the awesomestbowling alley & family entertainment center” and will not disappoint.
  7. And when the kids (or you) are going a bit stir crazy, check out the jump parks Jumpstreet or Xtreme Air in Chandler for a hopping good time.
