HVAC Terms Every Homeowner Should Know

Posted by
Ed Miller on Wed, Jan 15, 2014

  • HVAC: an all-encompassing term for your heating, ventilating, and air conditioning system
  • Thermostat: the main control system for your HVAC. In order to control the temperature in your home, thermostat utilizes sensors and relays to turn your HVAC system on and off.
  • SEER: Season Energy Efficiency Ratio. This term represents the measure of efficiency, either seasonal or annual, for your central air conditioner or heat pump. This measurement is determined from the varying temperature that occurs throughout each season, along with the average BTUs your air conditioner uses to cool your home during the cooling season. HVAC units with a higher SEER rating are considered more energy efficient. Most units manufactured in the U.S. must have a SEER of 13.
  • BTU: British thermal units per hour, which is the standard classification for HVAC units. It is used to determine the amount of energy required to cool or heat one pound of water by one degree. For example, 12,000 BTUs is equal to cooling one ton of cooling.
  • MERV: another common efficiency measurement, MERV stands for minimum efficiency reporting value. Most commonly, this measurement is used to rate air filter efficiency. A filter rated higher on the MERV scale will be better able to trap particles and keep them from getting into the air in your home. This higher rating also can translate into lower energy costs over the long run.
  • Split system: This is the most common type of heating and cooling system found in homes. It combines both an air conditioner (outdoor unit) and an indoor unit (air handler). A split system must always be paired correctly to ensure it runs efficiently. If you should require HVAC repair in Jacksonville, FL, be sure to have your technician check to see if your split system is paired up correctly.
  • Condenser fan: a fan that circulates air over an air-cooled condenser, which is located in the outdoor component of your HVAC system.
  • Condenser coil: This is also known as the outdoor coil and is a series of coils filled with refrigerant. As the refrigerant moves through the coil it is turned from gas into liquid to help cool your home and remove hot air.
  • Evaporator coil: This is also known as the indoor coil, and is a series of tubes filled with refrigerant. As warm air blows through these tubes, the heat and moisture are removed from that air as the liquid refrigerant turns from liquid to gas.
  • Refrigerant: This is a chemical used in HVAC units and refrigerators to move heat in and out of an indoor space. As the liquid heats up, it evaporates as it absorbs the heat.

Customer Reviews

This was an exceptional experience! We woke up to our A/C on but not cooling (it was 6am and already 81 in the house). The person who set up our appointment was very nice, able to get us seen same-day, and let us know of some options to help save us money.

-Christy Cormier

The service from Sam and Chris was excellent! They were very knowledgeable and professional. They were able to answer all of my questions and completed all of my electrical issues. I will definitely use them again for future jobs. Thank you!

-Adrienne Beal

From the get go I could tell that the Snyder employees were truly professionals and didn’t push to make sales like other companies I’ve talked to my whole life. They took the time to explain so that I could make a decision. The installers and later the duct cleaners were very respectful during their work here. Thank you.

-Mike Daniels

Snyder Heating and AC is dependable, always on time and techs have always been courteous and knowledgeable. Emanuel was a great addition to the company. He was friendly and knew what he was doing. Thank you for great service.

-Linda Ackley

Snyder came in and did a total overhaul of our duct system. They had a great knowledge of what to do to make our home so comfortable! The technicians were all so professional and took great care of us! We’re so thankful for their expertise. Great and easy communication with the call center. We will definitely use them again!

-Crystal Hill

Snyder provided an amazing experience from start to finish. Most of us dread getting estimates with pressuring salespeople. Erik was a great guy, explained all my options and didn’t try to pressure me to act quickly! Justin followed up with my husband and I to offer further assistance in our decision. Again, no pressure, just helped with our follow up questions.

-Michele Bauer

Very prompt, professional, courteous, and cleaned up after repair. Had water line break in my front yard and no pressure. Very pleased and would highly recommend Snyder for all your plumbing, and AC needs. Thank you for making a rough morning get better with ease and professionalism.

Snyder was easy to get in contact with and had availability the next day. Clint came out and needed some parts so had to reschedule us for the next day for installation. He did a great job converting our old 3 knob shower to one. Looks great! Professional and courteous. 100% recommend this company, especially Clint.
