New A/C Units

Air Conditioning – New & Replacement Units

Living here in the Arizona desert, our homes air conditioning systems go through some of the most rigorous work cycles throughout the country. Replacing your air conditioner unit is inevitable. When that time comes, Precision Air & Heating will provide you with the most comprehensive estimate for replacing your A/C unit.

Comprehensive Estimates

Why you need a comprehensive estimate

Before the era of tightly constructed energy efficient homes, it was common to install furnaces and air conditioners that provided substantially more than the necessary capacity in order to compensate for a homes vast inefficiencies. Over the years, many people here in Arizona have since upgraded to windows that are more efficient, caulking, weather-stripping, and better insulation for their homes. Unfortunately, what most homeowners do not realize is that simply swapping out their old A/C system for a new A/C unit the same size might be the worst thing they can do. In addition, newer A/C units do not have the same BTU ratings as systems even 10 years old, creating an even more complex technical puzzle. Therefore, simply going by the nameplate specifications from the old A/C unit could likely result in either an over-sized or even undersized new A/C unit. A system  that has been incorrectly sized will run inefficiently and cost homeowners thousands from purchase price to poor performance.

What goes into a comprehensive estimate?

To solve this complex puzzle of sizing the correct A/C unit for your home, every Precision Air & Heating customer receives a complete, No Charge New A/C Unit Estimate. No gimmicks, no hidden tricks, just a comprehensive evaluation that takes all the guesswork out of selecting a new heating and cooling system.

Common Questions

What do good central air units have in common?

The best central air units are reliable, efficient and quiet.  Today’s new central air units can cool more with less electricity and refrigerant than in days past due to massive technological improvements.  Still, even the top central air units require regular maintenance and cleaning to have a long, fruitful life.

What is R22 and how does the EPA phase out affect my AC?

There has been a lot of talk within the heating and cooling industry about the impending phase out of R22 and what that means to our customers. Information that is both factual and also misleading.

So let’s start with the basics. What is R22?
Hydrochlorofluorocarbon, is a colorless gas better known as HCFC-22 or R-22. R22 is the main ingredient used in air conditioning units for over the past 4 decades. Unfortunately, a byproduct of R22 when leaked into the atmosphere is a noticeable depletion in the Ozone Layer. There more detail on this by visiting the EPA’s Montreal Protocol. So, in 1992, The EPA began a phase-out of this ingredient due to these ozone depleting properties.

The original phase out of this mandate slated for a 90% reduction in R22 consumption by the year 2015 and a 99.5% near elimination of all R22 production by 2020. However, the EPA recognized that the industry was not on track to meet these mandates. So, in January of 2012, the EPA moved ahead deadlines by decreasing the overall allowable production levels of R22 by an additional 45%. Hence, the cost of refrigerant is now nearly double of what it once was.

At Precision Air we are not only in the business of serving our Customers but also leading the way within our industry. So, here is what WE are advising to be proactive with this situation.

As a home owner you have two options:
Option 1 is to attempt to maintain your existing system as long as you can without dangerous leaks. You can accomplish this with regular annual maintenance of your unit including a complete AC Tune Tune-Up.

Option 2 is to upgrade to new compatible equipment. While Option 2 will be the most recommended solution, it can be misleading. Most contractors will tell you that you need to upgrade to a new higher efficiency (non R22) AC unit. Actually there is a third option that may make sense for some home owners. There are some newer EPA approved Refrigerants like Dupont’s ICEION MO-99 being manufactured that will run in older R22 units. The cost of this refrigerant will be high and the performance could be substandard compared to the old R22 refrigerant. Please be advised that most of these replacement refrigerants including MO-99, may not yet be approved by manufacturers, and if mixed with your current systems R-22, it might and quite possibly will void your manufacturer warranty.

If upgrading to new unit is recommended, the good news is that many of these newer units actually cost less to purchase plus use significantly less energy then the older R22 systems.
So when your ready to consider repair or replacement of your old R22 AC unit, call Precision Air and Heating. All our technicians are NATE certified, the highest Certification available in the industry. Only a NATE certified technicians will be able to provide the most accurate diagnosis for your situation.

Why should I replace my existing heating or air conditioning system?

Heating and air conditioning systems get old, just like people, and eventually fail.  If you elect to replace your unit before it suddenly comes to a halt, you’ll have more control over the timing of replacement and type of furnace or air conditioner installed.  You’ll know it’s time to start thinking about a new unit when your current unit reaches about seven years of age, begins costing more to run than in years previous, or suddenly needs frequent repairs.

In the long run, you’ll be way ahead of the game  if you choose to replace your unit before it totally collapses.  Not only will you save a bundle because of the efficiency of a newer unit, you’ll also avoid costly repairs on your old unit.

How can I be sure my unit is the right size?

The best way to ensure that you have the correct sized air conditioner installed is to have an HVAC professional accurately measure and perform a proper new unit evaluation of your entire home .  There are a number of variables that go into calculations that determine how much tonnage any given home requires, including how much shade the outdoor unit will receive.

It’s important to buy a properly sized air conditioning unit. (This is one of those cases where bigger isn’t always better.)  An undersized unit may run all the time and still not completely cool your home.  On the other hand, an over sized unit will tend to short cycle, running in limited bursts that cool your home, but don’t remove excess humidity.  Short cycling is expensive, since the majority of an air conditioner’s energy is used during startup.

Which air conditioners are energy efficient?

All modern air conditioners are more energy efficient than older units—as much a 60 percent more efficient than similar units that were built just 10 years ago. However, some units are more efficient than others, and the more efficient your unit, the more cooling you’ll get out of the same amount of electricity.

You can compare new air conditioning units by their Seasonal Energy Efficiency Rating (SEER).  Higher numbers mean more efficiency.  Today’s typical low-end unit is a SEER 13, but units are available that exceed SEER 20.  By 2015, certain regions of the United States will be upgraded to a SEER 14 standard, meaning that SEER 13 units will not be be purchasable in these areas.  You’ll have to balance your desire for energy efficiency with your budget to determine what best makes sense for your home.

How long can I expect a new system to last?

Good air conditioners can last as long as 15 years if they’re properly maintained, but average air conditioners are expected to develop problems after seven to ten years if they’re neglected. Our Precision Plus AC Units come with a lifetime unit replacement warranty, the best in the industry. In order to maintain your AC unit and its warranty, it is important to perform yearly maintenance. If you want to get the most out of your new system, be sure to check your air filters monthly and replace them as needed, keep your outdoor unit clean and free of debris, and shade the unit during the hottest parts of the day. By performing a little easy maintenance, you can greatly extend the life of your air conditioner and keep it working at its best.

Why can’t I find the correct size air filter at my local home improvement store?

Some filter sizes are less common than others due to differences in manufacturing and material quality.  If you can’t find your filter at your local home improvement store, contact us and we can order the filter direct from the manufacturer.  You may discover that the filter that came with your unit is reusable, requiring you to only wash it gently once a month rather than replace it.  Reusable filters can be just as good at pulling dust and pollutants out of the air as disposable filters and are rated using the same scale.  For the best results, invest in an electrostatic washable air filter.  Premium brands like BoAir will offer a lifetime warranty making it an even more compelling option.
