When I moved into my first place, I couldn't believe how dirty everything was all the time. I found myself dusting and mopping continuously, only to deal with a fresh layer of grime later. After awhile, I realized that the problem was blowing straight out of my air ducts. My ventilation lines were so dirty that it was spreading grime through my house every single time the air clicked on. Fortunately, I called an HVAC contractor who was able to clean my vents to a gleaming shine. I know how big of a difference cleaning up your ventilation system can make, which is why I want to spread the word.
If you are having air conditioning installed in your home for the very first time, be aware that this is an appliance that you need to maintain over the years to keep it in good condition. That is why it helps to know some key terms related to central air conditioning that you'll run across that you may be unfamiliar with that will help you better understand purchasing a unit and its maintenance.
The only thing that you need to know about British thermal units (BTUs) is that it is the measurement of how much cold air an air conditioner can produce. Having a high BTU rating means that the unit is going to be stronger and use more electricity. It's recommended to hire an HVAC technician to measure your home's square footage, which will determine how big of a unit you need to have in your home. Units that are too small or too big can be inefficient, so bigger is not always better.
The unit located outside your home is known as the condenser, and it contains the condenser coil. This coil plays a key role in the operation of your air conditioner since it removes the heat found in the refrigerant lines and converts the gas into its liquid state.
Inside your home is the evaporator coil, which removes the heat from the air so that it is cold. It does this by converting the refrigerant from a liquid to a gas as it passes through the coil, which absorbs the heat as the air passes through the coil. The condenser coil and evaporator coil work together to help cool down the air in your home.
Every air conditioner will have a seasonal energy efficiency ratio (SEER), and as the name implies, this tells you how energy-efficient an air conditioner can be. Be aware that many states have minimum requirements for SEER ratings and that there is a theoretical maximum SEER rating at any given time based on how the technology of air conditioners have evolved over the years. Make sure you know what those upper and lower limits are so you can understand where your air conditioner ranks in that range.
Of course, selecting an air conditioner based on its SEER rating is something that a local HVAC technician can help you with. Reach out to one like Dale and Lee's Service Inc if you need help installing a brand new air conditioning system.
