What do HVAC accessories do?

Your new HVAC system needs support. Heating and cooling accessories are important to consider as you budget your investment in a new home comfort system. HVAC Accessories promise to not only allow your system to perform better, but also provide added comfort and convenience to you.

From smart thermostats that allow optimal temperature control straight from your phone to humidifiers, dehumidifiers, and air purifiers to clean up your air, all of the accessories below are part of your home comfort team.

What are the most important HVAC accessories?


Your thermostat maintains the temperature set forth by you in your home. Whether you are heating or cooling your space, begin by telling your thermostat what you want to feel and it will communicate those operatives to the rest of your HVAC system.


Air filters, as the name suggests, will filter particles, debris, and unseen allergens and dust out of the air that is being pushed into your home for your family to breathe. It is important to clean and/or switch out your filter frequently and use the best quality filters to ensure the health and safety of your loved ones – or your employees – within your home or business. To do so, look at the MERV (Minimum Efficiency Reporting Value) of the filter you plan to buy. This rating will help you understand – on a scale of 1 to 13 – just how efficient your potential filter will be in collecting particles. We recommend finding a filter with a MERV score of 6+.

Note: The higher your MERV rating, the less airflow your HVAC system will produce – as the filter will require the system to work harder to produce and move air. We advise finding a balance between the efficiency of the filter and the cost required to operate the system while using a high-efficiency filter.

Air Purifiers

Working against air pollutants such as smog, mold, and other mites and particles, your air purifier – a component built in to your system – will ensure the best-case scenario for air quality inside of your home or office. This HVAC element uses fan technology to suck air in, filtering it for better cleanliness and clarity and KILLING bacteria before pushing clean air out through your vents for you to breathe.


Humidification, like air purification, works as a component to your complete home comfort system.  Your humidifier will work to maintain the ideal level of humidity within your home. Optimal humidity is not only a factor for your home or office comfort, but also your well-being and, in certain cases, the condition of the structure and the objects within the structure.

Humidifiers work to add moisture to a room and boost the humidity in a dry environment. Contrarily, your air conditioner will work as a dehumidifier, drawing moisture out of the air in a space that is too damp and restore comfort and wellness. Together, they are the perfect pairing and ensure that your home is always at optimum comfort.

Humidity in the air helps to prevent dry skin and hair, damage to furniture, discomfort during periods of sickness where bloody noses and cracked lips are common, etc. Dehumidification via your AC will fight against mildew and mold spores as well as damage to wood or other materials that are susceptible to moisture rot.

CO Alarms

Not unlike a smoke detector, a CO detector or CO alarm detects carbon monoxide, also known as CO (standing for Carbon & Oxygen). Because over 20,000 people are sent to the emergency room annually in the United States because of Carbon Monoxide poisoning, CO has been referred to as the ‘silent killer.’

Carbon Monoxide doesn’t have a taste, an odor, or a visual appearance of any kind, so without a detector your family is at risk. Ovens, cars, lawn mowers, and many other home appliances emit Carbon Monoxide. If a malfunction or misuse occurs, the levels of CO can become toxic, if not deadly.

In 2016, most states require a CO detector in every home. They’re affordable and simple to install. Most importantly, they better ensure the safety of your family.

Don’t forget to ask your local HVAC dealer about the accessories right for your family.
