An HVAC breakdown is never fun, especially when you are unsure of what your evaporator coil is and why it should be fixed. Whether you’re a new or existing homeowner, many of these terms are quite beneficial to know. So if you are in need of an HVAC repair or in the market for a new one, here are the top terms you’ll want to know:

Thermostat: This is your primary source of controlling your indoor temperature. Usually located on your wall, some are a simple dial that you can choose your temperature, while modern day ones are programmable allowing you to adjust temperatures throughout the day. Wifi options are also available now, enabling you to set the temperature with just a click of your phone.

Filter: This is the part of your air conditioner that is responsible for your air quality. It’s a screen like part that helps trap particles so that they aren’t blowing through your home. Filter options vary, and some are even known to filter out allergens.

MERV rating: Your Merv or (Minimum Efficiency Reporting Value) is used to determine the effectiveness of your air filters. Your filters have tiny holes that allow air to pass through but blocks out harmful particles. The higher the rating, the more particles that are removed and the higher the air quality is.

BTU (British Thermal Unit):  This one is pretty important when it comes to new construction. BTU measures the size of the space that a unit will be able to cool. So if you are in the market to buy a new HVAC unit, you’ll want to check the systems BTU.

SEER (Seasonal Energy Efficiency Ratio): This term will come in handy if you are in the market for a new AC; the SEER rating is the measure of the efficiency of your central air. The rating is determined based on your average seasonal temperature, and the BTU’s (British Thermal Units Hour). The higher the rating means, the more energy-efficient the unit is.  

Air Handle: This is the part of your air conditioner that forces airs through the ducts and is located in your home. 

Evaporator Coil: This is the part of your HVAC system that is responsible for absorbing the and removing the heat in your home. It is found inside the air handler or attached to your furnace.
