Unlicensed HVAC Contractors Produce Messy Arizona Air Conditioning Consequences
Hiring an unlicensed HVAC contractor may seem a great method for reducing the costs of Mesa AC services or Mesa AC installation. But seeking services and skills from a bonded, insured and licensed Arizona AC Company provides better long-term solutions to your home heating and cooling requirements.
In this article, the techs from American Cooling and Heating provide Arizona residents a few tips on how to avoid the messy results of unlicensed HVAC contractors.
Phoenix Air Conditioning When Summer Takes A Break
Phoenix air conditioning and heat pumps bring home cooling during the summer and home heating during the winter. Yet the excessively warm nature of Arizona temperatures may cause a bit of lapse in winter AC maintenance planning. After all, summer reports from azcentral typically deal with record-breaking highs. For example: On Sunday June 19, 2016 temperatures in Flagstaff, Phoenix, Tucson and Yuma set various heat records. It was a day when Phoenix came in at 118 degrees while Yuma temperatures punched a record setting 120 degrees (1).
The need for severe winter weather air conditioning preservation is not foreign to regional Phoenix AZ.
Perhaps you remember the Phoenix freeze warnings during the December of 2015 NM blizzard (2). Local residents were cautioned to wrap pipes, protect weather sensitive plants, and take special care of outdoor pets. As to 2017, January should hang mostly in the mid forties, but may experience several drops to mid thirties. The following list reveals some of the recorded 2015 low:
- Flagstaff – 16 degrees
- Prescott – 17 degrees
- Mesa – 34 degrees
- AND Phoenix – 39 degrees.
In this article, American Cooling and Heating offers a how to on heat pump and Phoenix air conditioning preservation during severe winter weather.
Phoenix HVAC Preservation Tips – Dealing With Cold, Heat, Rain and Wind
Poorly maintained air conditioning systems are subject to unnecessary points of failure. Although crafted to withstand even extreme weather changes and conditions, HVAC systems perform better when homeowners follow basic air conditioning preservation practices. The following tips lead to increased longevity in both heat pumps and air conditioners.
1) AC Preservation – Avoid Covering Your System
Someone may consider a cover a sensible component of efficient Phoenix air conditioning preservation. This would be error. HVAC systems are designed to weather rain, snow and wind. Here are three reason covering an outdoor condensing system may actually damage the unit – even on a unit with a temporary disconnect from power:
- HVAC & Accumulated Moisture… No cover will effectively keep moisture out of external air conditioning components. Evaporation draws water up from the ground. Humidity in the air penetrates any break in the seal of the cover. The splash of raindrops promotes moisture accumulation within the confines of the cover.
- HVAC & Rodent Control… By nature, heat pumps and air condensing units are designed to deter rodents from finding sufficient cover for nesting. Don’t void this purpose by offering rats a nice, warm, cozy external HVAC system.
- HVAC & Effective System Airflow… Air conditioning systems function by effective movement of air. A cover can hinder the system to the point of critical breakdown. An even minor obstruction to AC airflow can increase accumulation of mildew and mold.
2) AC Preservation – Powering Down When The Power Goes Down
Bad weather sometimes causes a local outage of power. Problems during repair of the lines can cause multiple power surges to enter your home. If severe weather causes your household power to go out, you might consider tripping the main HVAC fuses until after the problem is fully resolved.
3) AC Preservation – Batting Down For High Winds
Just as installing a cover can damage the exterior components of your heat pump or air conditioning condensing unit, so can wind blown debris. Be prepared for high winds. Keep yard furniture, toys and brush secured, stored, or effectively distant from your HVAC system.

Maintaining A Comfortable Home Against High Temperature Arizona Summers
Home cooling in Arizona means installing air conditioning equipment that is capable of dealing with sequential months wherein the average temperature exceeds 90-plus degrees. In fact, Phoenix regional homes endure a season wherein heat increase rises well above 100-degrees for up to four consecutive months. It’s the kind of circumstances that make summer comfort almost as important as survival in below zero winter temperatures.
With each passing year it seems Arizona residents are pressed into even more days of unprecedented high heat index numbers. So even though Trane HVAC and other HVAC manufacturers continue to introduce better energy-efficient heat pumps and air conditioners, the cost of staying cool keeps rising. More hours of equipment operation means greater costs for comfort. The following tips show how to reduce the load on your Arizona air conditioning system.
Home Cooling, Reducing Heat In Your Home by Reducing Solar Heat Gain
People enjoy sunshine – even when the associated heat gain prompts increased energy consumption by home air conditioning systems. Weather that enables a wonderful day at the water park also forces higher cooling bills for the homestead. Longer hours of sunshine produce greater accumulation of solar heat gain. In the Arizona summer when the sun is higher in the sky, daylight hours increase and the associated heat gain accumulates even more. So keep the heat out. Here’s how:
- Install Sunscreens – Perhaps budget conditions forbid installation of window awnings. Take a look at sunscreens as an alternative solution. Crafted from wood panels or louvered slats, sunscreens fit over windows in a manner similar to shutters.
- Install Window Awnings – Whether crafted from rigid or flexible materials, window awnings reduce the heat that transmits through the windows of Phoenix houses. Even windows facing South or North can benefit from installed window awnings.
- Overhangs – If a home is already completed, this suggestion doesn’t apply to the circumstance. However, for Arizona homeowners in the process of building, or perhaps doing some major remodeling, crafting wide overhangs will help shield windows and doors from the blistering Phoenix regional summer sunshine.
- Plant Trees – If planted at a proper distance from the home, trees offer shade and reduced inside heat gain. But some cons exist: Even quick growing trees take many years to reach a height that provides full benefits. Also, if planted too near a home, the roots of the trees can end up causing issues with the foundation.
Home Cooling, Keeping the Heat Out and Reducing Indoors Heat
Stopping solar heat-gain involves external solutions. The second line of defense involves controlling heat gain from within the home. This means reducing indoor heat as well as keeping heat out.
Keeping Heat Out Improves Home Cooling Efficiency…
- Adequate Home Insulation – To keep a cool home, install sufficient and effective insulation in the walls, the attic, and the crawlspace.
- Managed Air Flow – Close the windows and doors. Latch them. Proper home cooling demands a tightly sealed home.
- Leak Prevention – Find the gaps around the doors, windows, vents and electrical outlets. Seal them.
Reducing Indoors Heat Assures More Efficient Home Cooling…
- Scheduled Applications – Appliances emit heat, some more so than others. Use a timer to schedule the dishwasher so that it only runs during the late evening hours. Plan clothes drying for late night TV time.
- Remember the “Off” Switch – From lights to televisions, stop burning electricity on devices not in use. Even small appliances resulted in accumulated heat spots.
- Ventilate – When bathing in hot water, use exhaust fans. Likewise when cooking on the range or even when running the dishwasher.
Home Cooling, Choose the Right Air Conditioning System
Home air conditioning systems strip heat from the inside air. This means more cool for you. But not all systems function with the same efficiency. Every Arizona home is different, and requires a precise cooling configuration of equipment and installation.
Ducted forced-air systems are the most common method of controlled home cooling. However, many components define the effectiveness of the installed A/C unit. Product selection based upon SEER ratings may seem simple and straightforward, yet the path to energy-efficient home comfort is often clouded by an assortment of additional calculations and considerations.

Air Conditioning Efficiency Compared To Other Forms of Energy Hungry Technology
They keep asking the question: How can we improve air conditioning efficiency? Yet one must really wonder if these wonder appliances designed to improve the human lifestyle are actually any less efficient than other forms of current technology.
To answer that, let’s take a look at recent reports posted in the pages of Scientific American. Accordingly, the United States expends more energy on heating and cooling than most any nation worldwide, averaging roughly 185 billion kilowatt-hours yearly (1). And it’s not all due to changes evoked by global warming or even by the current 20-percent growth rate of worldwide sales in air conditioning equipment. Face it: We live in an age when both businesses and homes expect year-around comfort. It means employees work more efficiently. Families rest more fully. In fact, throughout the industry of factories and care centers, HVAC equipment is often used to improve resident and worker safety concerns.
Yet to reap the benefits of modern air conditioning efficiency, we burn more fossil fuels than ever before in the history of man. Sometimes the HVAC is used for heat and sometimes the A/C is for cooling. We do so with the full knowledge that air conditioning bears with it a long-term price in energy consumption. However, according to the 2013 deputy director of ARPA-E, air-conditioning is “inherently inefficient.”
But what does this mean, this term “inherently inefficient?” By what comparison is the statement driven?
According to the deputy director, “It’s (air conditioning) everywhere and it’s (HVACR equipment) a huge energy sink.”
The imposed impression tends to define A/C equipment as though some great villain is loosed among us. But what is the measuring stick? Is it a comparison of comfort-to-cost versus necessity-to-cost? Or is the comparison merely applying performance and function to cost for usage? Furthermore unless the efficiency measurements that define the distinction between necessity and comfort meet criteria that are suitable to the homeowner or the business in question such measures are without value.
Average Energy Consumption For A Home Air Conditioning System
According to a recent article in Forbes, your home’s central heating furnace in off or standby mode uses roughly half as much energy per year as does a notebook computer in off or standby mode (2). That’s 300 Watts versus 600 Watts. Consider some typically monthly kWh usage in home appliances items functional under normal use cycles*:
- Refrigerator … 30-200 kWh/month
- Dehumidifier … 80-160 kWh/month
- Water Heater … Averages 400 kWh/month
- 2.5 HP Swimming Pool Pump … 350-450 kWh/month
- Central Air … 300-900 kWh/month
- Heat Pump … 600-1,800 kWh/month (heating and cooling.)
Most appliances do not run 24/7. However, items such as hair dryers, curling irons, and vacuum cleaners typically consume more energy per hour of usage than do modern refrigerators. Energy consumption must be measured in balance with the service performed. Without defining a scale for cost-versus-achieved-benefit, it seems senseless to isolate any single technology as though that technology is less efficient than some other form of technology. After all, in spite of government efforts to regulate and force improved transportation-related efficiency, automobiles can readily be defined as an unnecessary comfort that is in many ways “inherently inefficient.”
New Heating and Cooling Technologies and the Primary Focus Of Use
Clearly current technology in air conditioning efficiency has not reached maximum capacity. Conventional systems continue to use refrigerants in the core cooling process. For cooling, heat is absorbed and then expelled into the outside world. For heating with a heat pump, the process is reversed. And in either event, the HVAC process demands use of electrically powered compressors, fans and pump systems. Efficient air conditioning doesn’t necessary mean that consumers will receive a create decrease in the cost of operation. To rightly measure this process, we must always balance cost to effectiveness.
One new concept in heating and cooling involves replacing the typical super-powered fluids and gases with some form of solid material. By using materials such as bismuth telluride and other applicable solids as a means of absorbing heat, both refrigerators and other air conditioning equipment can be manufactured without use of so many moving components. This not only reduces the electrical demands, but it also reduces the possibilities of equipment breakdown.
One strange point mentioned during many of the discussions concerning new cooling technology always seems to involve not so much the concept of cost as it does the concept of “necessity.” And it seems often to be a “necessity” that is also directly linked to comfort. Certainly the greater measure of HVACR research seems focused on life-saving applications wherein refrigeration of medical supplies, food and more come to the surface as the front-runners. However there is also much concern about providing efficient dehumidifiers and air conditioning for American military personal stationed in extreme overseas hotspots. And lastly, but not necessary least important is the question of how the U.S. as a nation and how the world as a whole is going to efficiently adapt to a future of increasingly extreme heat waves?
Whether addressed as a “comfort” item or as a “necessity” item, we need air conditioning efficiency that includes cost-effective pricing, long-term energy efficiency, and effective performance. If air conditioning equipment is as declared by the 2013 deputy director of ARPA-E “inherently inefficient”, so too are our cars, buses and hot water heaters. HVAC technology is no less efficient than many other forms of modern technology. As to purpose performed versus the cost, for me A/C rates among the most valuable current pieces of home improvement equipment.

The Value Of Air Conditioning Your Attic
In a recent report concerning home air conditioning efficiency, the U.S. Department of Energy challenged the wisdom of locating HVAC systems in an unconditioned attic (1). So what brings about this challenge to conventional A/C handling methods? Why would anyone want to air condition a space that is not used for personal comfort? If typical U.S. housing construction involves placing the A/C air-handling unit in unconditioned attic space, what benefits can be achieved by flipping the coin?
Well, live and learn.
According to Energy.Gov, placing components of your home HVAC system within the non-vented control of an unconditioned attic can actually increase heating and cooling-related energy consumption by as much as 10%. Several reasons promote this concept. However air loss due to A/C duct leakage may be the major factor. Current research evidences that duct air leakage often exceeds twenty percent of the regulated airflow. And that, my friend, results in a significant and controllable loss of energy.
The evidence is in: Placing your indoor home HVAC components within a non-vented insulated and conditioned attic or crawlspace can provide a substantial reduction in energy expenditure. Although the attic may not be used as home living space, capturing and retaining the loss air flow results in improved home heating and cooling energy performance. However, fully sealing the attic tends to defy traditional house building codes. And we all know that things that defy tradition trigger an automated human resistance to change. So after years of being directed to construct your home with installed attic ventilation, why should we accept this notion of change?
New Understanding of Air Conditioning Efficiency
Perhaps you are unaware of current construction changes as they relate to the air conditioning industry. However thanks to Building America, since 2006 the practice of constructing vent-free fully insulated attics has been an accepted home construction building code. For over twenty years, the U.S. DOE has sponsored the Building America program as a focus for helping study and promote innovation in residential building construction. The introduction of non-vented attics is just one more successful endeavor. The primary purposes of Building America include promotion of:
- More affordable energy
- Greater product reliability
- Enhance product performance
- AND Better home comfort.
Along with other various energy-focused products and home design, Building American partners with world-class HVAC industry and HVAC research leaders to raise the standards in home air conditioning and A/C product performance.
Air Conditioning Efficiency Enhanced By Non-Vented Well-Insulated Attics
Ventilation enables moisture as well as warm air to escape from an attic. When attic-installed A/C equipment is not involved in the equation, vented attics with a well-sealed and insulated ceiling decks prove to be very efficient for helping reduce the cost of home air conditioning. However, if HVAC equipment, including air conditioning ductwork, is installed in the vented attic of an Arizona home, the energy consumption of that home may actually increase.
Yet conditions to exist. If your Arizona air conditioning is installed in a home not purposefully constructed for a non-vented attic, updating to new standards can be costly and difficult. For example: standard home roof structures often include slopes that are inadequate for installing attic-wide top plate installation. Furthermore, the typical home attic includes installed flues, hatches, water piping, electrical wiring, and various difficult-to-work-with knee walls and ceilings. Unless your attic can be completely sealed, some measure of air leakage is unavoidable. The result: an increase demand on your heating and cooling system.
Funds spend to increase Arizona air conditioning efficiency may actually increase your problems. It humid air from your living quarters escapes into a non-vented and conditioned attic space, condensation and moisture against the cold roof sheathing may become a potential calamity of accumulated mold and mildew. On the other side of the scale, if inside warm air seeps into a sealed and conditioned home attic it can heat the roof deck and result in an increased winter risk of ice dams.
In conventional vented attics, installed HVAC components are routinely exposed to the current external temperature extremes – extremes that may well increase due to additional complications related to home attics. Insulating and effectively sealing along the roof line of your home can provide better:
- Energy efficiency and savings
- Increased moisture resistance
- Reduced risk of wood rot and mold
- A more secure storage space
- And better wind resistance as well as increased fire and rain protection for your entire roof.
