3 Tips to Fix Pressure Balance Problems in Heating and Cooling

June 14th, 2013

Heating and Cooling Air Balance is a Tightrope Walk

Pressure balancing is probably the least understood, yet one of the most important, services provided by heating and cooling companies. Bottom line, it’s all about achieving the right balance of negative and positive air pressure. Too much of either can create problems. A neutral system is ideal and what is ultimately needed for the healthiest air inside a home. Neutral will also result in lower utility bills since conditioned air is not escaping through cracks and crevices and outside air isn’t making its way indoors. A neutral to slightly positive air pressurization will provide the most comfortable atmosphere and prevent outdoor contaminants from entering the home.

An energy audit can determine if your home has positive or negative air pressure, what’s causing it, and how the home can be brought to neutral. Audits should be done by honest, certified technicians who work at established heating and cooling companies.

Negative air

The condition in which too much air is drawn into your home and not enough allowed to pass through is called negative pressure. This means that unfiltered and unhealthy air has a welcome mat waiting for it. Outside air contains many pollutants and, especially here in the desert of Arizona, dust has a way of infiltrating even the cleanest of houses. All that outside air being sucked into your home because of a negative pressure system can lead to asthma and allergy problems and other health risks caused by dust, mold, carbon monoxide, and other airborne contaminants.

Some of these issues can be addressed by simply sealing windows and doors with weather stripping and caulking, especially if the home is older, though any leaks in ductwork should always be repaired before adding more insulation.

Positive air

When conditioned air is allowed to escape through windows, doors, into your attic, and beyond, this is called positive air pressure. All the warm or cool air your system just worked so hard to create goes right out of the house when there’s positive air pressure. Just as in a home that has negative pressure, weather stripping, caulking, and proper insulation are important requirements towards reaching neutral air pressurization. Beyond that, installing baffles, vents, transfer grilles and ducts, or return ducts, or closing existing ones, may be the answer, depending on each room’s pressure issue.

Monsoon Season in Arizona

June 13th, 2013

Arizona’s official monsoon is June 15th through September 30th. These storms range from minor dust storms to intense thunderstorms. The monsoon usually starts with heavy winds, which can turn into a wall of dust hundreds of feet high moving across the Valley. These dust storms, called haboobs, are often accompanied by thunder and lightning and sometimes lead to heavy downpours. It’s the only season during which Arizonans don’t use the phrase “it’s a dry heat”.

The Arizona Division of Public Health Services describes AZ heat as “more than a nuisance – it is lethal.” And the severity of annual monsoons affects our roadways – including driving visibility and flash flooding – as well as air quality. A 10,000 foot-tall wall of dust, 30 or more miles wide can do a lot of damage, especially to a home’s HVAC system.

Since a home’s air conditioning system filters the outside air, the dust storms that are part and parcel of a monsoon can strain your unit, making it work harder and less efficiently. Because the a/c unit may run longer than normal due to the higher humidity, homeowners may need to lower the thermostat setting in order to keep comfortable. 77 degrees in a 50% humid home does not feel good. Cleaning the unit’s condensate drain will also help keep your HVAC system clean and clear out any debris, which makes the unit more efficient.

Because the electricity often goes out during the monsoon, it’s best to turn your air conditioning unit off so there’s not a huge power draw when the electricity comes back on. In fact, investing in surge protection is also a wise move, considering you’re a/c is the biggest power draw in your home.

Although you should call John’s Refrigeration Heating and Cooling if you have issues with your a/c unit during the monsoon, after all the dust has settled, make an appointment with us and our certified technicians will check your home’s HVAC, including duct work and air quality, to ensure your family is breathing fresh air. After all, we are your indoor comfort specialists.

Quality Home Comfort Award to John’s Refrigeration

June 4th, 2013


John’s Refrigeration of Mesa AZ was recently named one of Contracting Business.com magazine’s 2013 Quality Home Comfort Award winners.

Their project is a system renovation and retrofit in the 4,000 sq. ft. home of Bill and Aimee Edwards of Scottsdale, AZ. The Edwards suffered from a lack of comfort in their home and were looking for someone who could provide a cost-effective solution. By listening to their customer and doing a thorough investigation of their home and mechanical system, the team at John’s was able to discover that the homeowners had uneven temperatures throughout their house, high utility bills, and a significant dust problem. They also discovered that the Edwards’ home suffered from major duct leakage, not enough return air, and a lot of duct routing problems.

By paying attention to the details, working to correct the problems in a cost-effective manner, and then testing their work and properly commissioning the system, Johns’ Refrigeration was able to solve the issues and create a much more comfortable and healthy indoor environment for the Edwards family.

The Quality Home Comfort Awards is a program the Contracting Business.com magazine launched in 1991 to recognize quality in professional residential HVAC contracting. Since that time, more than 100 outstanding HVAC projects have been recognized. Winning projects, like the John’s Refrigeration effort, will be featured in the July, 2013 edition of ContractingBusiness.com magazine and posted online.

John’s Refrigeration Has the Cure for Your Home’s Illness: Indoor Air Pollution

June 3rd, 2013

The Environmental Protection Agency (EPA) has named indoor air pollution as one of the top 5 environmental risks to public health. They also report that indoor air can be up to one hundred times more polluted than outside air. These pollutants, combined with the Valley’s excessively dry air, make you more vulnerable to harmful viruses and respiratory ailments.

Since your home’s HVAC system helps control the environment (temperature, humidity, air flow, and air filtering) where you and your family spend so much of your time, having a clean and efficient system results in cleaner air within that home. Filtering pollutants keeps you and your family healthier, which also reduces healthcare costs. With an efficient filtration system in place and a well-maintained unit, your family are less likely to be exposed to the airborne pollutants that irritate asthma, allergies, and which even contribute to fatigue.

To contribute to the health of the home’s occupants and ensure efficient HVAC (heating, ventilation and air conditioning) system operation, it’s important to perform routine maintenance. Think of it like preventative medical care, but for your house. After all, you wouldn’t wait more than a year to have your teeth cleaned.

John’s Refrigeration offers an Advanced Oxidation Air Purifier for your house. The oxidants this unit creates circulate around your home, along with the treated air, and neutralize microbials at the source. This means your home will stay cleaner, smell fresher, and be healthier for you and your family. This whole-house air cleaner filters through our state-of-the-art system every time your system runs, reducing allergies and removing odor, bacteria, mold, and viruses.

John’s also recommends using electrostatic filters, which have filtration media made from unique polyurethane and polypropylene blends. Unlike fiberglass and pleated air filters, electrostatic air filters tend to hold onto particles so well that they will remain in the filter from the time they’re caught until the time they’re flushed out. Also unlike fiberglass and pleated filters, electrostatic filters are reusable and are cleaned by simply removing the filter from the vent and vacuuming off the dusty side with the hose attachment on a vacuum cleaner. If dirt and dust remain after vacuuming, the filter can be flushed out with a hose and left to air dry. So, not only are these filters more economical because you don’t have to keep buying a new one every month, they’re also better for the environment: both inside your home as well as by not contributing to landfills.

John’s Refrigeration Heating and Cooling will install an electrostatic filter or Advanced Oxidation Air Purifier, making you breathe easier and feel healthier, all the way around.

What is HVAC?

May 28th, 2013

Literally speaking, HVAC is an acronym for Heating, Ventilation, and Air Conditioning. But what exactly does that mean?

Most people associate a Central Air Conditioning System with HVAC. This is a system in which air is treated at a central location in a home or other building and distributed to and from rooms by one or more fans and a series of ducts.

The heating part of an HVAC system usually refers to the way air, water, or steam is heated using a boiler, furnace, or heat pump to distribute air – via ductwork – throughout the space. Ventilating is the process of removing or changing air in a space to create a different temperature or to reduce or remove moisture, odors, smoke, dust, or even airborne bacteria within a space by bringing air in from the outside to replace inside air. Air conditioning is simply the removal of heat from a space.


The largest component of your home’s HVAC system is the outdoor unit (a condenser) and an indoor unit (an evaporator coil). Another main component of an HVAC system is the ductwork.HVAC systems help control the environment (temperature, humidity, air flow, and air filtering) and keep occupants comfortable by regulating the temperature and air flow by using air distribution to deliver and remove air from different spaces. These systems are also important to the health of the occupants, because a well regulated and maintained system will keep a home free from mold and other harmful pollutants.

Because the HVAC system in your home uses more energy and drains more energy dollars than any other system in your home, it’s important that it’s sized correctly. Otherwise, the result will be an inefficient system that will not only cost more money in the long run, but won’t cool or heat a space properly. The efficiency of HVAC systems is rated by a Seasonal Energy Efficiency Ratio (SEER), typically ranging from 13 to 23, with the highest numbers indicating the most efficient units that offer the most energy savings year after year.


After one of John’s Refrigeration Heating and Cooling NATE certified technicians reviews your HVAC system, we’ll diagnose the problem, explain what needs to be done, and make sure you understand your options.

We’ll also present you with a guaranteed price before starting any work so there are no surprises later on. Equally important, our trucks are stocked with hundreds of parts, allowing us to complete most repairs during that initial visit to your home, which means a faster return to full indoor comfort. What’s more, we back all of our repairs, parts, and labor with a two year warranty.

John’s HVAC installation, repair, and maintenance services will make you feel comfortable, all the way around.
