How Your Air Conditioning Components Work

No matter the size or efficiency rating every AC unit consists of the same essential components:

  • CONDENSER — The outdoor portion of your AC unit and heat pump that releases and collects heat, depending on the setting and time of year.
  • COMPRESSOR — Part of the condenser, the compressor pumps refrigerant throughout your system to cool your home.
  • EVAPORATOR COILS — These coils are either attached to your furnace or inside the air handler, absorbing heat from the air inside your home.
  • REFRIGERANT — The chemical used to produce a cooling effect on airflow throughout your home.
  • DUCTWORK — Made of either metal or synthetic material, the ducts transport air throughout your home.

During proper operation, warm air flows over the refrigerant in the coils. This process causes the refrigerant to turn into gas, which travels through the compressor and applies pressure to increase the temperature of the gas significantly.

Coils located within the condenser draw wasted heat from this process and send it out of the system — cooling the refrigerant back into a liquid and chilling the air. Then, the cool air travels through your ductwork and your home.

Life Expectancy of an Air Conditioning Unit

One of the most frequently asked questions customers ask is, “how long will this last?” And we always reply that it completely depends on a few factors.

On average, a full central HVAC system can last anywhere between 10 to 25 years. Your usage, the type of equipment and maintenance affect the ultimate life expectancy. Most importantly, proper maintenance plays a huge role in prolonging the life of your air conditioner.

Several factors may reduce the lifespan of your air conditioning unit, including:

  • Poor maintenance practices
  • Poor quality or defective components
  • Over- or under-sizing the system for the residence or property
  • Improper installation
  • Improper usage, such as heating or cooling with windows and doors open
  • Unusually high usage

The Need for Preventative Maintenance

At Homesense, we strongly believe in prevention. While your system still functions properly, we recommend that you commit to regular maintenance to prolong the life of your HVAC system. Three key maintenance checks to add to your calendar include:

  • Change your filter regularly (every 1-3 months).
  • Keep your outside unit clean and clear from debris.
  • Schedule professional maintenance checks at least twice a year.

Possible Causes of a Broken Air Conditioner

Over the years, we have seen many reasons for air conditioning systems to break down or operate poorly. Here are some of the primary issues that cause malfunctions for air conditioners:

Old Filter

Outdated air filters easily become clogged and restrict airflow throughout your entire unit, which decreases the system’s ability to cool the air inside your home. We highly recommend you clean or change your air filters at least four times a year (use the seasons as a reminder), or even better, once a month.

Low Refrigerant

Your air conditioner uses refrigerant to remove heat and humidity from the air in your home. Your system can sometimes develop leaks in the refrigerant lines, meaning insufficient refrigerant circulates through the system to properly cool the air.

There are also some potential warning signs that indicate you may be leaking R22 or R410A refrigerant. For example, your A/C may blow lukewarm or hot air. You may hear a hiss or bubbling noise coming from a leak in your refrigerant line. Additionally, your refrigerant line may have ice on it.

To test for leaks and diagnose the problem, there are three leak tests to consider:

  1. Electronic Leak Detector Test.
  2. Nitrogen Leak Detector Test and Bubble Test.
  3. Dye Test.

Unfortunately, fixing a low refrigerant problem does not equate to just replacing the refrigerant. To fully remedy the issue, a home air conditioner repair technician needs to find the leaks and repair the holes in the lines — often a time-consuming process with multiple leaks.

Blown Capacitor

The capacitor stores energy and enables currents to pass through so your system can turn on and off when desired. Without a properly functioning capacitor, your entire HVAC unit cannot turn on. Capacitor failure can be a more common issue and usually be fixed for under $300.

Compressor Failure

When dust, grime and dirt build up on your condenser coil, the air conditioner cannot expel enough heat from the system. Consequently, it forces your system to constantly run in an effort to cool your space.

Many times, it overheats your compressor and causes it ultimately to fail. A compressor failure often leads to a recommendation to replace. The compressor is probably the biggest and most expensive part in your air conditioner or heat pump, and the repair is labor intensive.

Blocked Airflow

There are several reasons why your air conditioner may experience blocked airflow.

  • LEAKY AIR DUCTS — This is the most common cause of bad airflow. It allows air to escape and your HVAC unit works less efficiently.
  • CLOGGED AIR CONDITIONER COIL — Dust builds up on your air conditioner coil, which reduces the amount of airflow your furnace distributes.
  • DIRTY FAN BLOWER — When dust builds up on the fan blower it reduces its efficiency, preventing proper air distribution throughout your home.
  • BROKEN AIR DUCTS — Disconnected or crushed air ducts also cause bad airflow because air cannot properly circulate throughout your home.
  • INCORRECTLY-SIZED HEATING AND COOLING SYSTEM — The size of your air conditioning system should be determined prior to installation. If the system is undersized or oversized, you may experience airflow issues, as well as short cycling and strain on your equipment.

Frozen Air Conditioning

Your evaporator coil, located inside the blower cabinet, may freeze and prevent your air conditioner from working properly. This coil sucks hot air from inside your home and moves it outside. If your refrigerant levels are low, the evaporator coil cannot gather enough hot air to cool your house. Over time, moisture collects around the coil and freezes, preventing refrigerant from flowing freely throughout your system.

Sadly, homeowners cannot do much to repair a frozen air conditioning unit. We strongly recommend turning your AC unit off, and calling an HVAC professional to remedy the problem.

How To Do Your Own Home Air Conditioning Service – DIY Tips

Not all issues with your air conditioner require a service technician to come out to your home for an inspection, especially if you do not need emergency service.

Things to Check on Your Air Conditioner Before you Call a Pro

We suggest checking the following to see if you can make any of your own home AC repair:

  • BREAKER OR FUSE — If your AC does not turn on at all, it could mean that you have blown a circuit breaker or fuse. First, make sure your AC is receiving power from your electrical panel. Second, reset the circuit breaker. Third, replace your fuse.
  • THERMOSTAT SETTING — You may experience issues with an improperly set or faulty thermostat. Check the settings to make sure the thermostat reads “cool” when you want the A/C turned on, instead of “off” or “heat.”
  • CONDENSATION SENSOR — There’s a sensor on your condensation tray that will turn your A/C unit off when there is an overflow of water being collected. Check this tray to see if it is full, and if so, empty it and see if your unit turns back on.
  • BLOWER DOOR ON AIR HANDLER — Check your air handler to make sure the blower door is securely closed. Otherwise, your A/C unit will not turn on.
  • BLOCKED CONDENSER — Check to see if your condenser is blocked by weeds, grass or other airborne debris. If it is, remove the blockage and clean the condenser.
  • CHANGE FILTER — Pull out your air filter to see if it needs to be replaced. We strongly recommend cleaning or changing your filters at least four times a year (when the seasons change) or, better yet, once a month.
  • REGISTER DAMPERS — If your A/C is turned on but not cooling the air, check your register dampers on the vents in each room to make sure they are set to the open position.

How to Stay Cool While Waiting for Home Air Conditioning Repair Services

If, after checking all these items, your system still needs repairs, here are several ways you can stay cool while waiting for an HVAC technician to arrive at your home:

  • COVER WINDOWS — Close your curtains, turn down the blinds and pull down your shades. Keeping heat from the sun out during this time is the easiest way to keep your house as cool as possible. Once the sun goes down, open your windows and let the warm air out and cool night air inside your house.
  • CHANGE CEILING FAN ROTATION — Make sure your ceiling fan rotates counterclockwise during warmer months. This particular rotation pulls warm air up toward the ceiling. Most fans should have a switch on the side that allows you to reverse the blade direction.
  • TURN LIGHTS OFF — Keep as many lights off as possible during the day. If you need lights on, keep in mind that LED and CFL light bulbs generate the least amount of heat, while incandescent bulbs create the most.
  • COOK DIFFERENTLY — While waiting on home air conditioning repair services to be made, reconsider using your stove or oven as they generate a large amount of heat in your home. Consider eating leftovers or preparing salads or picking up prepared foods from the grocery store.
  • INVEST IN DEHUMIDIFIERHumidity levels are high in Indiana, and a dehumidifier will keep the air inside your home dry. Investing in a dehumidifier can be particularly important in the rooms where your family spends the most amount of time, increasing comfort levels without increasing air conditioning.
  • SLEEP SMARTER AND BETTER — Choose cotton sheets and wear cotton pajamas. Also, take a cold shower or dip your feet into cold water before going to bed, and unplug electronics to reduce the total heat circulating throughout your room.

The Home Air Conditioning Replacement Process

If it is time for your air conditioning system to be replaced, here are some tips when shopping for a new unit.

Comparing A/C vs Heat Pump

While a heat pump looks exactly like an outdoor A/C condenser, the difference lies in the fact that both heating and cooling occur within the heat pump. On the other hand, an A/C condenser works with a split system, where cooling happens within the outdoor unit and heating takes place within the indoor furnace.

When to Replace Both A/C and Furnace

In some situations, it can make the most sense for you as a homeowner to replace both your air conditioner and furnace at the same time, but not always. Here are few tips on when and when it may not be in your best interest to replace your entire HVAC system:

3 Reasons to Not Consider:

  1. Your furnace is less than 10 years old and has no issues.
  2. You don’t have the money to responsibly replace it now, or you have other large financial priorities at the moment.
  3. You are planning on moving within the next year.

4 Reasons to Consider:

  1. Your furnace is more than 10 years old and has had some issues.
  2. Resources are available to replace them both now.
  3. Your home has a downflow furnace, which means your existing furnace has to be completely removed in order to replace your air conditioner.
  4. You want a high-efficiency air conditioner, in which case you are required to also replace your furnace with a high-efficiency option.

How to Shop for the Best Air Conditioning Repair Services Provider

Shopping for a new air conditioning system can be a foreign process. After all, it is not something you face on a regular basis — hopefully, at least. To help, here are five steps to help you get started in researching your Indianapolis HVAC service providers:

  1. RESEARCH CUSTOMER REVIEWS — Go online and see what other people are saying about the HVAC companies you’re exploring. Check out Google and Yelp reviews to read customer reviews and better understand how consumers make decisions about their particular unit and technician.
  2. REQUIRE MULTIPLE OPTIONS IN ESTIMATE — Ask the HVAC professional you’re working with for multiple options within your estimate. Try to get at least three options included. You only shop for a new HVAC system maybe once a decade, so you want to fully understand the scope of market values and the cost-benefit analysis of all the different options.
  3. ENSURE UNIT RIGHT-SIZE FOR HOME — You want to make sure your unit is properly sized to the space you are heating and cooling. Technically speaking, this is called a heat load calculation, which determines the right amount of British Thermal Units (BTU), or output of your air conditioner per square footage.
  4. ASK FOR QUALIFICATIONS ON INSTALL TECHNICIAN — Don’t be shy about asking the HVAC company for the specific qualifications of the technician who will be installing your unit.
  5. TAKE TIME TO MAKE BEST DECISION — Purchasing a new HVAC system is a big decision, so take your time and don’t feel rushed. Do plenty of research, read reviews from other customers, and know your technician. One night of uncomfortable temperatures will be worth a lifetime of making the right choice.

Standard vs High-Efficiency Units

When deciding between a standard vs. high-efficiency air conditioning unit, it’s important to understand the similarities and differences.

Similarly, both units effectively cool your home and offer similar life expectancy with good maintenance practices. Additionally, both use gas and electric power sources and work well with smartphone thermostat options.

Conversely, high-efficiency units include higher seasonal energy efficiency ratio (SEER) ratings, meaning more air gets cooled for less energy (and money) — usually provide payback within 3-6 years of your purchase. More specifically, the variable speed blower and dual heat exchangers use less electricity and gas, respectively, to increase home interior comfort, and the unit’s advanced control board also allows for predictive alerts to homeowners and HVAC companies when issues arise within the system.

So how do you know which one to choose? Here are three questions to consider when deciding between a standard vs. high-efficiency unit:

  1. How many days will you be using A/C?
  2. What is your current electric bill during these months?
  3. How long do you plan to own your home?
