Furnace Installation in Tumwater, WA 98512

“In November 2018 I had Pacific Air install an electric furnace in my old manufactured home. It was my 1st experience with this type of purchase—-needless to say I had a lot to learn! I got 4 quotes and have no quarrels with any of the companies that I did not choose. Pacific Air impressed me from start to finish! Pacific Air explained to me the whole process to a much deeper degree than the other companies. Data was collected on my home and entered into a program that determines the proper furnace for my home. I was invited to side by side with the teck and watch the process; all the while every detail was being explained to me. Then the document was printed out for me to keep. I was soooo impressed! The teck talked to me about my old furnace and educated me on my new one. I had three furnaces to pick from –different price ranges. All explained to me with no hurry on the tecks part. I asked lots of questions and received good answers. Since this is a new experience I did do research on my own too. I choose a furnace and not the cheapest. The furnace was installed and the inspector passed the install. I give Pacific Air 5 stars plus! While I have no quarrels with the other companies; SOME tecks entered my home took some quick data and wanted to leave (were there 5 minutes or less). I had to ask them to sit down for I had questions. Guess Pacific Air just really spoiled me!!!!!! Anyone who reads this, just remember its always good to get several quotes, for you will see how different companies handle their business. I almost picked another company, was impressed, but realized I had only their quote! Mary”

How Does Your Central Air Conditioner Cool Your Home?

April 17, 2019

Aside from the professionals, like ours at Pacific Air Heating & Air Conditioning, who really thinks about air conditioners and their components? Air conditioners keep your Olympia, WA, home or business cool and comfy when the outside temperatures are high, and that’s all you really need to know, right?

Well, air conditioners do so much more than just cool, like dehumidify your home or business and help keep your inside air cleaner. Understanding a bit of its basic components and how they work can help you identify a problem or malfunction when it occurs.

Air Conditioner Overview

As already mentioned, your air conditioner does more than just cool. It dehumidifies by reducing the volume of humid air, thereby taking a portion of its moisture. That’s the reason for pans and drains with air conditioners. Your air conditioner also aids in cleaning the air by removing allergen and debris particles from the airflow where they attach to the filter. 

But the largest purpose of your air conditioner is to remove the heat from your inside air and cool it, providing the maximum indoor comfort. Looking at this side of your air conditioner, most conventional central air conditioners have a hot side, which is located outside, and a cool side, located inside. Since these air conditioners have both outdoor and indoor components, many times you’ll see your air conditioner referred to as a split-system air conditioner.

In the very basest of explanations, here’s how your air conditioner works:

  1. Air conditioners transfer heat to the outside, extracting it from the inside air.
  2. The compressed gas refrigerant in the system (you probably know DuPont’s Freon® refrigerant) absorbs the excess heat before it’s pumped through the piping in a closed system to an outside coil.
  3. A fan blows air over the hot coil, transferring the absorbed heat in the refrigerant to the outdoor air.
  4. Since the inside heat has been removed, the indoor air is now cool. As a result, the refrigerant is re-cooled and condensed here, then sent back to circulate through the system to begin the process again.

There are many complex and smaller transactions throughout your air conditioning system, but this gives you an overview on how your system works.

Air Conditioner Components

An air conditioner is made up of many components, but the major parts doing the heavy lifting of moving the air indoors and outdoors are the evaporator, condenser, expansion valve, and compressor. Keep in mind they’re each either located outside (the hot side) or inside (the cool side).

  • Evaporator
  • The evaporator is located on the cool side. Its main function is to receive the liquid refrigerant. It’s paired with a fan blowing air over the chilled coils into your home. After it receives the liquid refrigerant, it converts it to gas through a drop in pressure.

  • Condenser
  • The condenser is located on the hot side. Its main function is to facilitate heat transfer. Resembling a car’s radiator in looks, it actually works the opposite of the evaporator by converting the evaporated refrigerant back into a liquid. This process is called a heat transfer, working on the principle that heat will always move from a warmer to a cooler substance.

  • Expansion valve
  • The expansion valve is located between the evaporator and condenser coils. Its main function is to regulate the refrigerant flow into the evaporator. It removes pressure from the liquid refrigerant allowing the conversion into gas to occur in the evaporator.

  • Compressor
  • The compressor is located on the hot side. Its main function is to pressurize refrigerant. The compressor is a large electric pump re-pressurizing the refrigerant gas to convert it back into liquid. It assists the condenser, while the expansion valve assists the evaporator.
