Talking to Your HVAC Technician

If you have ever listened to an HVAC professional, then you know that they may sound like they are talking a completely different language. The truth is that many of these terms are not that hard to understand and if you know these then you will know what a person is saying to you when it comes to your heating and cooling system. So let us get started with the most basic of terms and that is what the term HVAC stands for. This stands for Heating Ventilation and Air Conditioning. This is a term that will refer to all things that are related to this subject.


The next term is Thermostat. This is the thing that you will adjust on a regular basis to make the room cooler or hotter. This is what you use to set the temperature that you want the room to remain at. These can go out and as such will lead to your system not working right and you need to call a repairman on a number of occasions. Today, there are many different kinds of thermostats. You can get digital, programmable, and even smart thermostats. Go through the different options with your technician to make sure you have the perfect thermostat for your home and need.


The unit refers to the system that you have installed. This encompasses all aspects of the heating and cooling system and when these are not working properly, this can lead to a lot more serious issues.
