Central vs. Ductless Air Conditioning

There are quite a few kinds of air conditioners, but not all are equally suited to residential usage. Here is a comparison of two popular residential air conditioning solutions: central and ductless mini-split systems.

Central air conditioners are simple and effective. Central air conditioners extract heat from regular air and then distribute the resulting cool air throughout your home. Central air conditioning is often the best choice when you are looking to cool your entire home, but it does require a little extra maintenance. Not only do you need to keep the air conditioner in working order, but you also need to make sure that your ventilation isn't getting clogged up.

Ductless Mini-Split systems are similar in that they have a central cooling unit and outlets throughout your home. You can choose which rooms get cold air at any time. While a central system uses ventilation to move cold air, a ductless system has refrigeration lines that directly connect the refrigeration unit to the fan systems in each room. This cold air is then blown right into the room, somewhat like a cleaner swamp cooler.

So which option is better?

Central air conditioners require much less effort to install if you already have ventilation in place. They are also pretty good choices if you are planning on keeping all of your rooms equally cool.
Ductless systems are easier to install if you don't have ventilation already. They are efficient if you are only planning on cooling a few rooms since they allow you to save energy that would otherwise be spent on bringing down the temperature in the rest of your house.

How Big Does My Central Air Conditioner Need To Be?

In past blog articles, we shared that having an oversized central air conditioner can cause you a number of problems. These issues can include your house becoming too humid, increasing the operating cost, and creating a risk of breakdowns. So, this likely has you wondering what size air conditioner you actually need. Today's article hopes to explain what goes into determining the best size.

First off, it is important to understand that size really does matter. A unit that is too small will continuously run, will not be able to keep up on hottest days, and will ultimately increase your energy consumption. On the other hand, in addition to what was stated above, an air conditioner that is too big will cost more to run, will cycle on and off frequently, and will not provide consistent cooling. You may be tempted to look at your existing unit to determine the right size, that is very often an unreliable method.

In order to figure out the correct size unit, an air conditioning installer must calculate your home's heat load, which is essentially how fast your house heats up. Factors to consider is the home's overall volume, the exterior area exposed to direct sun, and the number and condition of your windows. Also considered are the age and overall condition of the house, the type of insulation in the walls and attic, and any existing ductwork. Even the type of roof you have has an impact.

When you know your home's heat load, you then know exactly how much cooling power you need. Regardless, this is not something that can be done by the average homeowner or some online calculator. Only a qualified and professional air conditioning installer knows what to look for and has the software to make a precise calculation. Installing a new air conditioning unit is just one of those home repair projects that a person cannot do on their own.

Common Air Conditioner Noises and What They Mean

On a hot day, the last thing you want when you turn on your air conditioner is for it to start making noises that remind you of a 747 heading down a runway or rocks being tossed around inside a steel drum. The following are a few of the most common air conditioner sounds that you might encounter and what they mean.

Screaming:
You turn on your AC and hear a high-pitched screaming or hissing sound similar to a tea kettle coming from the outside unit that stops within a few seconds. The air conditioner may also cycle on and off frequently. This is usually the result of high pressure building up in your system and causing the compressor to scream. You should immediately turn off your AC and call for service.

Knocking, Banging, or Clanging:


If you notice this sound when the outside unit is running but not when you set the thermostat to fan only, the most likely cause is an obstruction. The fan may be hitting a rock or stick or may have come loose from the mount causing it to wobble inside the cage. You should turn your air conditioner off and call for service.

Gurgling or Bubbling:


It may be hard to identify the source of the gurgling, but it is most likely the condensate drain line or a refrigerant leak. You probably will not make the problem worse by continuing to run your AC, but you should make sure that you have a proper trap for the condensate drain line. You should also call a professional to rule out a refrigerant leak.

Screeching:


A metal-on-metal screeching sound while the AC is running typically indicates that the fan motor bearings are worn and that the fan motor should be replaced. You should avoid running your AC if possible and call for service.

Squealing:


If there is an intermittent squealing coming from the inside unit, you may have a worn or misaligned fan belt. The sound may come and go as the belt expands and contracts with changes in heat and humidity. Your AC may continue to run for a while, but it is best to go ahead and call for service since the belt will eventually break and leave you sweltering in the heat.

Clicking:


If you hear a sound similar to a baseball card in the spokes of a bicycle tire, there is probably a small obstruction in the fan of the outdoor unit. You should remove the obstruction before continuing to run your AC. If the outside unit tries to turn on but only clicks, you may have an electrical problem involving the compressor, thermostat, or capacitor.

Any type of strange noise coming from your AC should be evaluated by a trained HVAC professional. J.R. Perkins Heating and Cooling has been serving homeowners in Scottsdale and the surrounding area since 1960.

Why Is My Central Air Conditioner Blowing Hot Air?


Is your central air conditioner blowing warm or hot air? When a customer asks these questions, they are understandably frustrated and aggravated. However, if you are experiencing this problem, there is no reason to sweat. While you may ultimately need a professional technician to inspect your air conditioning unit, there are some things you can do before making that call.

The fact is, there are many different reasons why an AC could blow warm or hot air. Regardless, the most common causes are simple. Today's article will walk you through some easy, do-it-yourself troubleshooting.

Causes of a Central AC Blowing Warm Air
1. Check Your Thermostat - believe it or not, having the thermostat set to "heat" is likely the most common reason for this issue. Also, with the fan switched to "on" means it will blow continuously, even when the AC unit is not cooling. So, the fix is simple. Switch the thermostat setting to "cool" and the fan to "auto."

2. Clean the Outside Unit - Bad weather can cause debris to build up around the air conditioning unit's components. These components require unrestricted airflow in order to draw the warm air from your home. Try sweeping away any visible debris and trim nearby hedges and any tall grass that could be getting in the way.

3. Check the Power - Your air condition unit is actually two parts. It is possible for the outside unit to lose power, but your inside unit to push warm air throughout your home. First, check your circuit breaker box to see if the breaker tripped. Next, find your "emergency shut off" switch, likely located on the home’s exterior wall. It can sometimes get accidentally switched off.

Today's article discussed some common causes for a central air conditioner blowing warm or hot air, and the easy do-it-yourself fixes. Nevertheless, if you still have a problem, it is time to call a professional air conditioning repair technician. You may have a refrigerant leak, damaged duct work, or another condition. Only a professional can properly diagnose and repair these problems.

What If I Need Air Conditioning Service Repair?

When your air conditioner goes out, it can be a disaster - especially in the summer in Scottsdale AZ. Getting your a/c back up and running again will become the number one priority. This does raise some very important questions:
  • Can I repair my air conditioner myself or do I need to hire someone?
  • If I do need to hire, should I hire a local contractor or a company professional?
  • Can our budget afford this? What kind of pricing will I be looking at?
  • How long will this take? Is it going to be anywhere between a day and a month?
  • Does the repair service come with a warranty? If it quits again in a month, will they come back out for free?
The answers to these questions can fluctuate, the main reason being the difference between having built-in heating and cooling for the home, or if your home is equipped with window unit air conditioners or portable ones. Typically, window units and portable air conditioners do not need to be repaired, simply replaced. The exception to this is if they are still under warranty and the manufacturer or business where they were purchased will repair them for free or a small fee.
With in-home cooling, whether you decide to hire locally or through a business, all of the above questions can be easily answered through their available website. If it does not list prices, area availability, time frames, warranty guarantees, and if there are any available promotions, there should at least be a contact number available to speak with someone in person about these questions. Any information you get through the website or through an individual, I would get a copy of in e-mail. This will ensure that if you end up speaking with someone else, you are still able to get the original terms you were quoted.

Solve Uneven Cooling With These Tricks

Uneven cooling is a common problem, especially in multi-story homes. Dirty filters, ductwork issues, or the age of your air conditioning system can all affect how well your AC cools the various parts of your home. If one part of your home feels like a sauna while another feels like Alaska, the following tips may provide a solution.

Check Your Vents:
Start by making sure that all vents and registers are free of dirt and debris and that they are not blocked by furniture or other items. If the second floor of your home is overly warm, you can partially close some of the first-floor vents. This will help direct more of the cool air to the second floor of your home.

Adjust the Fan Setting:
Most people keep the fan setting on their thermostat in the "auto" position. This means that the fan only runs and circulates air during the cooling cycle. Switching the fan to "on" allows it to continue to run even when the rest of the system cycles off, which can help even out the temperature throughout the house.

Check for Leaks:
Small holes, tears, and gaps in your ductwork can allow cool air to escape before it reaches its intended destination. Ductwork leaks also force your air conditioner to work harder, which can significantly shorten the lifespan of your system. An HVAC professional can inspect your ducts and make any necessary repairs.

Add Insulation:
Adding more insulation to your attic will help you get more out of your air conditioner by keeping the cool air in and the hot air out.

Upgrade Your AC:
Although it does require a larger financial investment, a new zone cooling system will give you the flexibility to independently control the temperature in various parts of your home. An HVAC professional can help you design a zoned system based on the size and layout of your home along with how you use the various spaces within the home. If your air conditioner is more than 10 years old, it is probably time to considering replacing it. Air conditioning technology has improved significantly over the past decade to provide greater comfort and energy efficiency.

What Are the Benefits of Using a Programmable Thermostat with my Air Conditioner?

The big benefit of a programmable thermostat, with your air conditioner, is that it will save you money and energy. Programmable thermostats are able to store settings for different times of the day, and different days of the week, so that you are not running your air conditioner full force when you are not home. For example, you could set a programmable thermostat so that your cooling system does not work very hard while you are at work or on vacation. As a result, you can potentially save up to 10 percent on your home cooling costs with just a 7 to 10 degree setting change for the 8 hours you are at work. How does that sound?

Before the advancement of microchip technology, the typical thermostat used a rather unsophisticated mechanical mercury switch. The switch tilted one way when the temperature was achieved, turning off the cooling system. When the house started to warm again, the switch tilted the other way, and the air conditioner turned back on. It was all very simple and very easy, but was a bit inaccurate and required manual setting. Microchip technology advanced thermostats, making them more accurate, user-friendly, and far more efficient.

However, while a basic programmable thermostat has many great features like a 7-day programmable schedule, holiday recognition, and diagnostic features, technology continues to advance. Today, you can install a smart thermostat. Smart technology is loosely described as everyday items and appliances with internet connectivity. Therefore, smart thermostats allow you to control your home's temperature using a smartphone, tablet, or computer. Moreover, smart thermostats have the power to learn your behaviors and preferences, and will begin to make automatic adjustments based on things like today's weather or if it detects you coming home early (via your smartphone's location).

Ultimately, whether you choose a programmable or smart thermostat, all are certified by the government to have features that will help you save energy. That said, with proper use, they will not only save you money, but they will also improve your comfort at home. Look for a thermostat with the ENERGY STAR logo on the package.
