what features accessories add ons extras i need hvac systemHVAC systems are a central aspect of your environment—controlling air flow, temperature, air purity, and the overall quality of the air you breathe.

To make the most of your HVAC system, there are a few accessories that are critical, and others that—while luxurious—are not necessary.

This article pinpoints the accessories and features required to keep your HVAC system running smoothly, as well as some of the more indulgent features that just make life a little easier.

Crucial HVAC Accessories


Dirty Air FilterOne of the main purposes of an HVAC system is the circulation of high quality air.

To keep your air fresh, clean, and void of contaminants, your HVAC pushes the air through a series of filters. Different systems require different types and sizes of filters, but the logic behind it is all the same.

Regular replacement of your filters is key to maintaining top notch air quality. An overused air filter builds up dust and dirt, clogs your system, and blocks airflow—making your system work harder and your energy bill go up.

The US Department of Energy recommends changing your air filters every month or two during high use seasons.

Basic Thermostat

Thermostats serve as your control panel and are your point of access to the heart and veins of your system. Without one, your HVAC system would either sit dormant forever, or be forever running at a constant pace.

A thermostat with basic options allows you to control the rate of airflow and the temperature of your air.

With a basic thermostat you have to press a button every time you need to turn your unit on or off, but it gets the job done. Other, more advanced thermostats exist to help save you hassle and money on electrical bills.

Supplemental HVAC Accessories

Programmable Thermostat

There is a deep range of programmable thermostats available on the market. They can be as simple as letting you set a temperature for a certain time of the day, or as complex as allowing you to map out the entire week’s airflow schedule.

Programmable thermostats save you money by turning on and off automatically according to a schedule you set, meaning they aren’t left on while you are away.

However, to really take advantage of any energy savings you need to be smart in how you schedule your airflow. Automated schedules turn on units even on mild days just because they’re programmed to.


Humidifying FeatureDepending on where you live, some people might consider a humidifier or dehumidifier an essential part of their HVAC system.

Dry climates use humidifiers to make the air a little more comfortable and breathable. More humid climates use dehumidifiers to suck moisture out of the air for comfort and as a means to control mold.

While these accessories may be necessary in some climates, they are often supplemental features used on and off to add comfort, and are not critical to the overall functioning of your HVAC system.

If you don’t want to install this part on your HVAC system, you can also purchase stand-alone humidifiers and dehumidifiers for single room solutions.

Multistage HVAC System

HVAC systems can be either one or two stage. A one-stage system is your basic configuration, allowing you to turn on and off your unit without controlling the rate of the airflow.

Two-stage (or multistage) systems work like a dimmer on a light switch. They have a high and a low setting so your unit can feed air to you quickly or slowly—depending on what you require.

While a single-stage system will get the job done, multistage systems are more efficient and distribute air more evenly across your space. It’s not necessary to have multiple airflow settings, but it can end up saving you money.

Unnecessary (But Still Fun) HVAC Accessories

Smart Thermostat FeatureSmart Thermostat

What makes a thermostat smart? They are a step above programmable thermostats, building upon those features with the ability to learn your behavior and produce real-time energy consumption data.

They even have sensors that can test humidity levels, or see if anyone is home and make its own adjustments.

These thermostats typically have a sleek, modern design, and cost several hundred dollars.

If you are installing a new HVAC system, or if you’re just looking for some upgrades, it’s always a good idea to consult with experts.
