To understand the working of an HVAC system, you must first understand how each part contributes to your house’s heating, ventilation, and air conditioning.

Furnace – The component utilizes natural gas or oil to heat the surrounding air. The furnace also entails a heat exchanger, the primary constituent responsible for heating the air to the right temperature. You will typically find a furnace at a remote place in a residential or commercial establishment, including the attic, basement, or a specially designed closet space.

Air Conditioner – You might know what an air conditioner does, but how does it achieve the result is a mystery we will unravel right now. The air conditioner utilizes the air outside. The air further passes through the compressor unit, which contains coolant, the liquid responsible for dropping the air’s temperature. You can call for HVAC repair services San Antonio if your air conditioning unit is showing signs of malfunctioning. As the hot air rises into your room, the AC unit inducts it and throws out dense, cold air into your home or workplace environment.

Thermostat – Consider the thermostat the mastermind behind everything that goes on in operation. With the help of a thermostat, you can turn it off and on, control the temperature settings, and operate the features that your HVAC system might exclusively entail.

How do modern thermostats work?

Modern thermostats work a tiny bit differently than conventional systems. It is because the contact is not exposed to the elements. Modern thermostats hold the contacts behind the glass for protection, resulting in uncoiling once the temperature drops. The contractors further use a series of magnets and a steel bar to close the circuit when the temperature drops below the prescribed setting. Similarly, it works oppositely when it needs to turn off the furnace. Modern thermostats are far more superior than their conventional counterparts. Apart from this, they also reflect durability since a glass veil protects the electrical contacts.
