What is HVAC? HVAC stands for “Heating, Ventilation and Air Conditioning.” Sounds pretty simple right? Well, it can actually be a lot more complicated than you might think. What many people don’t realize is that HVAC systems include not only heating and air conditioning but also ventilation. In this article we will define the term “HVAC” by discussing each of these three components individually so that you know what they are and how they work together to keep your home comfortable all year round!

What is AC And What Does It Do

AC, or air conditioning, is the process of removing heat from a space. HVAC systems will cool an entire building when it becomes too hot outside and also provide warmth in cooler months! AC works by blowing cold air over your skin and lowering the temperature to around 68-72 degrees Fahrenheit. This can be done using specialized cooling coils that are cooled with liquid refrigerant under high pressure (called “chilling” coils). The refrigerant then turns into a gas which evaporates some of its water content (called “condensation”) as it flows through these coils due to lower atmospheric pressure found inside buildings versus outdoors. In other words, one coil takes energy out while another absorbs energy back in; so together they balance out the efficiency needed.

What Is Heating And How Does It Work

Heating uses the same principle, except this time you’re using hot air to reduce your skin temperature. The warmer coils are cooled with a gas called “natural gas.” This is also the type of heating which produces heat on demand when needed and blows it out through an electric fan (called “forced-air” or sometimes just convective).

During the winter, your furnace starts taking the brute of the work. . It’s usually a gas or oil burning machine that will have its own fan and heat exchanger. Inside of it, you’ll find a natural-gas (or oil) burner with an electric ignition system which heats up the metal coils inside to as much as 2500 degrees Fahrenheit. These hot coils are cooled by high pressure air from an “air handler” unit outside your house. This is where things start getting clever…

The size of your home’s HVAC system

Determining the size of your HVAC system is quite simple. All you have to do is follow the instructions for solving this math problem: Total square footage of your home X 0.08 = size in tons (or BTU’s) If you have a house that is 1200 sq ft, then it will need 120 tons or 10000 BTUs to cool and heat properly throughout the year. For every 1000 sq feet over the initial figure, add 12 tons/BTUs per hour to estimate how many more are needed during peak seasons. For example if your house is 1400 sq ft., then it would take 132-144 tons or 11000 – 13400 BTU’s respectively.

Common Problems With HVAC Systems: 

– Leaks. Air conditioning units need to be properly sealed and insulated in order for the system to work efficiently. When it is not, cold air may escape through any openings or cracks that exist around your home which will make your unit have to work harder than necessary.

– Dirty filters. The filter of an HVAC system should be changed every month and inspected regularly as well since dirt can clog up a cooling coil or restrict airflow into the compressor causing costly repairs down the line….

– Blowing air. If the air coming out of your vents is not blowing at a decent temperature, it may be because there’s an issue with one or more components in the HVAC system that needs to get fixed as soon as possible….

– Dirty coils. The evaporator coil inside your unit can accumulate dirt and other particles which will have a negative effect on its ability to cool down your home effectively.

– Poor insulation. Insulation plays an important role in protecting yourself from rising energy costs by reducing heat loss during winter months when you need the most heating…..

Service Your AC Annually 

Servicing your AC system annually is an important part of making sure it runs efficiently and lasts. The AC system should be serviced by a professional every year to check for dirty coils, clean ducts, and other potential issues that may arise during the time between annual visits. Servicing your HVAC unit on a regular basis will help identify any problems before they can become costly repairs down the line. There are many reasons why you should get your air conditioner serviced at least once in a 12-month period–the most obvious being safety due to potentially lethal gas leaks in refrigerant lines.  Because there are so many components involved with this highly technical device, routine servicing will also save customers money over time because it lowers the risk of failure with the systems.

A/C Maintenance Tips 

When it comes to your HVAC maintenance, there are a number of things you can do that will save money. Here are six tips that any homeowner can use:  -Clean or replace the filter at least monthly -Use an ice cube tray and water to find where cold air leaks originate from in your house -Have ducts cleaned every 12 months by professionals (and check for dirty coils) -Replace old thermostats with new programmable ones because they control temperature more efficiently but still allow homeowners some input if desired -Turn down heat when no one is home to avoid using energy unnecessarily while nobody’s around The bottom line is this–if these steps seem like too much work for you then get someone else who knows what they are doing.
