Air Conditioning Basics

The four main components to your air conditioner are:

Condenser: The condenser is the outside metal unit and where the gas from the compressor is condensed into a liquid. The gas entering the condenser is very hot. The temperature is then lowered, so the gas can convert back to a liquid.

Compressor: The compressor is inside the condenser. It circulates the pressurized refrigerant, to concentrate the heat, and changes the low pressure gas to high pressure.

Evaporator: The evaporator is the part of the system inside the home. In simple language, it absorbs the heat from your home.

Expansion Valve: The expansion valve controls the amount of refrigerant in your system.

All of these pieces are connected by a copper tube that handles refrigerant, creating a closed loop. Heat is collected in the evaporator, sent outside to the condenser. The heat is removed, and the cool air is recirculated back into your home.

AC Facts

An Air Conditioner Doesn’t Create Cool Air.
What happens in the AC process is actually the removal of heat from the air. Your AC uses a chemical called refrigerant to remove heat and transfer it outside. The warm air runs through the lines and coils in your unit and goes from liquid to gas and back again. During this process, the refrigerant removes the heat and transfers it elsewhere so that when the air comes out the other side, it is cool.

Your AC Will Remove Humidity.
Lower humidity helps the overall comfort level in your home by making you feel cooler, even if the temperature is the same.

Your Air Filter Needs To Be Checked And Replaced Every Three To Six Months.
(depending on the manufacturer’s recommendations)
A dirty air filter restricts your air flow, which reduces efficiency, costing you money, and over time can put stress on your unit and could cause a costly repair.

Maintenance, Maintenance, Maintenance.
Your air conditioner needs regular checkups to keep it running in tip-top shape. Having regular annual preventative maintenance will bring your system longer life and fewer breakdowns over all.

The Seasonal Energy Efficiency Ratio (SEER) measures air conditioning and heat pump cooling efficiency, which is calculated by the cooling output for a typical cooling season divided by the total electric energy input during the same time frame. A higher SEER rating means greater energy efficiency.

At MD Repair, we provide all the services you need to keep your AC running in top-notch shape. Call us at 816-690-7985 for repairs, maintenance, or new-system installation.

“Had Joe out to look at my ac units.
I expected a healthy bill with a rushed technician. It was the total opposite. Joe fixed the issue that ended up being a simple fix. He took the time to educate me on what I can do to help my ac run more efficient. Something no other company has done. He was friendly, knowledgeable, and not in a hurry like most.
Awesome service! Best I’ve had and I’m happy to say this is my go to HVAC company. I even called my mom and had her put MD Repair’s phone number on her fridge.
I’m so thankful there are honest people like Joe!”

“It all started with a quick and free estimate.
M.D. Repair installed new furnace and a.c. in half a day and did a fantastic job. They also built in a slot for the furnace filter so we do not have to take furnace cover off to change. They even checked our existing humidifier to make sure it worked with new system.
Thank you to everyone involved at M.D. Repair”

Air Conditioning Repair in Raymore, MO

Just wanted to take a moment to express my appreciation for M.D. Repair getting someone out to fix our AC so quickly.
Jacob was very professional, efficient, and thorough in checking out our AC and getting us back up and running. He was right on time and called when he was on his way so I wasn’t guessing all day. He even helped educate us on what to look for and how to properly maintain our hvac systems. Will definitely call back next time we need our heating/cooling systems checked.
