Common Repair Issues with Commercial HVAC

Friday, February 27th, 2015

A broken commercial HVAC system may be cause for alarm during very hot or especially cold weather. If business must be put on hold due to uncomfortable conditions for clientele and employees, you may end up losing a lot of money. Keep your unit from breaking down in the middle of a busy day by scheduling repairs at the first sign of trouble.

When you receive complaints about the HVAC system in your building in Tempe, call Johns Refrigeration as soon as possible. We can address any of the following problems or aid in solving any issue that comes your way.

  • Poor heating or cooling: A commercial heating and AC system is made up of a lot of complex components. While all of these components are necessary in maintaining ideal conditions, there’s also a lot that can go wrong. When one part is not working properly, it may have an impact on several other components within the unit. If you notice that your property does not seem to reach the temperature on the thermostat–even by just one or two degrees–call a technician now so you won’t have to deal with more costly repairs later on.
  • High energy bills: Chances are, you’re never thrilled about your office’s utility bills when they cross your desk. But if you’re worried about your commercial unit, don’t just simply make an automatic payment without paying attention to the cost. Check to make sure there are no major differences from month to month, or from year to year in the same season. A spike in costs could indicate trouble.
  • Loud noises: Sometimes, strange noises from the HVAC unit mean that repairs are urgent. Other times, it could just indicate a loose panel or screw is clanking around, disrupting the work environment. Regular maintenance can help prevent even the smallest of problems from disturbing your property.

Maintenance involves cleaning, adjusting, and inspecting the unit, a job that a trained technician is best qualified for. Call Johns Refrigeration today for maintenance or any repairs you may need for yourcommercial HVAC system in Tempe.

What Are My Heating Options in Tempe?

Thursday, January 15th, 2015

There is a huge amount of heating options available to homeowners today, so many that it can easily be overwhelming.

  • Do you want a combustion heater or a heat pump?
  • If combustion, what fuel do you want it to burn?
  • If heat pump, do you want a central unit or a ductless system?
  • If you aren’t sure about any of those questions, don’t worry.

We’ve got a short summary below of some of your heating options in Tempe.


Furnaces are the most popular kind of heating system in the country. They’re relatively cheap, versatile, and put out a lot of heat relative to the amount of fuel burned. Most furnaces operate on natural gas, which is piped in by the city. In areas where natural gas is not an option, however, electric and even wood burning furnaces are still an option. Furnaces are a great option for those who want a sturdy heating system that can last a long time.

Heat Pumps

A heat pump does not burn fuel to create heat, like furnaces do. Instead, it evaporates and condenses refrigerant to move heat from one area to another. This makes it extremely energy efficient, because it’s moving preexisting heat from outside into the home instead of creating it. It’s also safer, as it doesn’t have any toxic byproducts of its operation like furnaces do from burning natural gas. Heat pumps are a good choice for people who want to save money and live in more temperate climates.

Ductless Mini-Split Systems

A ductless mini-split is just like a heat pump, but built to only heat one room instead of the whole house. Why would this ever be desirable? Well, for one thing it avoids losing heat to leaks in the ductwork, something that a lot of forced air systems suffer from. For another, it offers the added ability to set a different temperature in each room with a ductless system. Ductless systems fit the needs of those who want a finer level of control over the climate in their home.

If you’re in the market for a new heating system, call Johns Refrigeration. We provide heating installation services throughout Tempe.

How to Reduce Strain on Your Air Conditioner During a Heat Wave

Friday, July 18th, 2014

“Heat wave” is a relative term in the Valley of the Sun. Standard summer days in Tempe count as roasting heat waves for most other parts of the country. So what we might call a “heat wave” mean that it isextremely hot. Either way, we have numerous days that will place enormous stress on the cooling systems in our home, and this pressure will cause them to wear down faster, leading to repairs and a shortened service life.

But there are ways to take some of the strain off your AC during the worst of the heat. Although you will depend on your air conditioning in Tempe, AZ to help you through most of the summer, you can relive the work stress placed on it through a few basic steps and some professional assistance from an experienced AC company like Johns Refrigeration.

Here’s our advice for keeping a healthier cooling system during the days of the Anvil of the Sun.

Have Regular Maintenance from a Professional

You should have a maintenance visit from an HVAC technician annually, no matter the weather. The best time to have maintenance done is in spring, but it is never too late to schedule it during the summer. Without maintenance, your air conditioner will start to run with additional stress. This will not only raise your power bills, but will cause the air conditioner to overwork. You risk a serious breakdown during the summer each time you go without a maintenance visit that year.

Maintain a Steady, Comfortable Thermostat Settings

Thermostat control is something people rarely do well during a heat wave: they crank the thermostat down to the lowest possible setting (usually 50°F) to combat the higher temperature. However, the thermostat is not a throttle: it will not producer higher levels of cooling when set lower, it will only remain on longer to try to reach the lower temperature. This puts enormous stress on the system, and it will result in a temperature that is too low for comfort. Instead of dropping down to the lowest setting possible, set you the thermostat at around 72°F, which is comfortable for most people, and keep it there. The AC will work less and you won’t sacrifice comfort.

Reduce Extra Sources of Heat

Watch for places in your home that produce additional heat that contributes to the high outdoor temperatures. Draw the blinds over windows that face the sun. Turn off all unnecessary lights. Avoid using appliances such as washing machines, dishwashers, laundry machines during the hottest parts of the day. Keep doors and windows closed. If you have an attic, make sure that it is properly insulated, since it will become incredibly hot from sun exposure and this heat will seep down into the rest of the house.

To get started with easing the stress on your air conditioning in Tempe, AZ, call Johns Refrigeration and sign up for our Peak Performance Club. We offer two 51-point inspections each year (the second is for your heater) and many other membership benefits.

How to Tell It’s Time to Upgrade My Air Conditioning

Monday, June 23rd, 2014

Few appliances have more importance for a home in Tempe than a powerful and effective air conditioner. We can experience warm temperatures even during the winter, and the summers soar above 110°F regularly. If your air conditioning system in Tempe, AZ has started to approach to the end of its service life, you need to know the signs so you can arrange for a replacement before the system either becomes too expensive to operate or it breaks down permanently during one of the hottest stretches of the summer.

Here are a few signs of impending air conditioner replacement that our team at Johns Refrigeration would like to share with you. We are here to help with a professional opinion if you are unsure if it’s time to install a new AC. If you are ready for a new cooling system, we will use our more than 40 years of experience to help you find the right replacement and install it so it will provide you with many years of cool summers (and winters, springs, falls, etc.).

Watch For These Warnings That You Need To Upgrade Your AC

  • Excessive age: The manufacturer of your air conditioner set an estimated lifespan for the system. Although it’s possible to exceed this number with the proper maintenance care, you should still give serious consideration to replacing the unit if it has gone a few years past this. The chance of the system starting to decline and waste money increases with each year past this estimate—it’s safer to get ahead of these problems.
  • Extremely noisy operation: An AC that makes constant clanging, grinding, and groaning sounds has probably aged past the point where it can efficiently do its job; the components are too worn down to work well. A single unusual noise can mean a problem a targeted repair can fix. But with an older system, constant sounds are a sign of an impending breakdown… unless you replace the system first.
  • Elevated utility bills (with no relief in sight): When your electrical bills start to rise while the AC regularly operates, than the system has probably permanently lost its efficiency. If maintenance and repairs do nothing to stop the rise of electrical costs, than the air conditioner is no longer worth keeping, and it’s time to arrange for a new installation.

Call for the AC Professionals

Making the choice to replace a cooling system is a large one, but in many cases it’s the most economical and cautious one. Call Johns Refrigeration for help making this choice, as well as for the expert installation for your new air conditioning in Tempe, AZ if that ends up as the best decision for your comfort and your budget.

How Much Does Efficiency Matter with New Air Conditioners?

Friday, May 23rd, 2014

“Energy-efficiency” is one of the key phrases heard when it comes to modern appliances. We live in an era in which people want the devices they use on a daily basis to work well without putting an undue drain on energy resources. Technological progress has increasingly pushed to reduce the amount of power that machines need to work effectively, and today we have many choices for high efficiency systems for our home.

Like air conditioners.

The efficiency of an air conditioner is easy to discover: it’s listed as SEER, “seasonal energy efficiency rating,” a measure calculated from the ratio of the cooling power of an AC (in BTUs, British Thermal Units) to the energy consumed (in watt-hours) averaged over a season. The higher the SEER, the more efficiently it converts electrical power into cooling.

When you are looking for new air conditioning in Tempe, AZ, you will need to consider SEER as well as other factors. Johns Refrigeration can help you make the ideal choice for your home, and we will install your new system so it works its best for you. Contact us today to set up an appointment or request an estimate.

Efficiency is important for your energy budget

The most important information that SEER tells you is how it will save you money over a season of cooling. A system with more than 14.5 SEER qualifies for the ENERGY STAR label from the U.S. EPA and is considered an excellent choice for saving money. The higher the number, the more you can expect to save during a season.

Efficiency is important for service life

If an air conditioner has high efficiency, then it puts less pressure on its components in order to run. This means it will last longer on average than comparable systems with lower SEER. When you invest in a high SEER air conditioning system, you are making a long-term commitment to energy savings.

Efficiency in not important for cooling power

This is where people sometimes make a mistake: just because a unit has high SEER doesn’t mean it is automatically the best choice. Aside from high SEER air conditioners costing more, they may not actually provide enough cooling for a home. Energy-efficiency only measures the ratio of cooling power to energy consumed; a system can very efficiently make use of power, and yet still not produce the amount of cooling needed to evenly condition a house. You must balance SEER with other factors in your home so that you have the perfect air conditioning in Tempe, AZ that cools you down and saves money.

Let the NATE-certified technicians at Johns Refrigeration handle your air conditioning installation. We will make sure that we put in a system with the best balance of SEER and other important factors.
