Installing A New Air Conditioner For Next Season? Use These Terms To Boost ROI

You’re hardly alone if you equate the prospect of installing a new air conditioner to learning a foreign language. Compressor? Condenser? What’s the difference?

The solution? Educate yourself to understand the basics of how an air conditioner works. No one expects you to become a certified HVAC expert at the end of the process. But the knowledge you gain will help make you an informed – and confident – consumer. It also might mitigate the stress of making this major financial investment.

So take notes, if doing so will help you understand how an air conditioner’s key components work together to bring cool air to your home:

  • The network of tubes through which refrigerant flows is called the coil.
  • The “heart” of any central A/C unit is the compressor; it sends the coolant from the indoor evaporator coil along to the outdoor condensing unit and then back to the evaporator.
  • The coil that triggers the refrigerant gas to emit heat to its surroundings and become a liquid is called the condenser.
  • The coil that allows the refrigerant to absorb heat, causing the refrigerant to boil and turn into a low-temperature vapor, is known as the evaporator. 
  • The expansion device releases the pressure created by the compressor, which causes the temperature to plummet and the coolant to become a vapor/liquid mixture.This is called a TXV – thermal expansion valve – typically found in equipment with higher SEER numbers.
  • The plenum is essentially an air compartment that forms part of the system for channeling cooled air.
  • The coolant (also called the “refrigerant”) circulates through the air conditioner — at turns absorbing, transporting and releasing heat.

These well-calibrated machines have undergone many changes in the last 20 years, and the U.S. Department of Energy has led the charge with its line of Energy Star-qualified products. Quieter and infinitely more energy-efficient than their clunky predecessors, and those that only meet the government’s minimum efficiency standard, today’s A/Cs can save you a significant amount of money on your cooling costs.

Combine your newfound knowledge about installing a new air conditioner with the expertise of Apollo Home Electrical, Heating, Cooling & Plumbing. When it comes to learning the foreign language of A/Cs, let us be your interpreter, and we’ll guide you to the best choice for your greater Cincinnati area home.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
