Your HVAC system is capable of controlling indoor temperatures, but it can only do so much. The air quality and level of moisture inside your home or office is something your HVAC alone cannot solve. You should consider adding more features to your HVAC system to address such air quality issues.

DN HVAC Services offers a selection of accessories and components designed to improve the functionality of your HVAC systems. We can add these optional systems as part of a new installation procedure or as a retrofit or upgrade to an existing HVAC. The accessories we offer include:


Thermostats are the perfect choice for those looking to make efficient use of their HVAC systems. Programmable thermostats can be set to automatically balance the amount of forced air an HVAC provides to any given space, based on temperatures and/or time of day. You can save a considerable amount on your energy costs if you have a reliable thermostat installed for your HVAC.

Carbon Monoxide Detectors

These safety features are a must-have for furnace owners, especially for those who are particularly safety-conscious. Carbon monoxide is a virtually untraceable gas that is colorless, has no discernable scent, and is tasteless—it is also highly poisonous, and is most often released by leaking furnaces. These detectors can warn you of a carbon monoxide leak, even if you cannot perceive one, allowing you, your household, or your co-workers to take decisive action before tragedy strikes.

Air Filters

Any system that uses and/or produces air needs a filter to keep things clean and clear. HVACs are sure to take in their fair share of dust, pollen, and other airborne debris during their useful life. To prevent these particulates from contaminating the air and causing health problems, you will need to occasionally replace your old filters for new ones every now and then.

Humidifiers and Dehumidifiers

There is more to the quality of indoor air than just particulates and temperature—there is also the matter of humidity. Too much water vapor in the air can encourage the growth of molds and fungus, create muggy conditions when paired with hot temperatures, and can make breathing difficult for some. Too little, and the risk of you contracting infections or colds increases—your eyes and skin could dry out from this. To prevent both situations, humidifiers can be used to increase the humidity of a space, while dehumidifiers can lower humidity (and even eliminate nasty odors).
