Heating & Cooling FAQs

What does HVAC stand for?

HVAC is your heating, ventilation, and air conditioning system. This term may be used to describe a furnace, heat pump, air conditioner, boiler, or ductless mini-split.

Do I need HVAC maintenance?

Maintaining your heating and cooling equipment is akin to getting an oil change for your car. You don’t have to schedule this service, but it will help the system run more efficiently, break down less often, and last longer.

What is a ductless mini-split?

A ductless unit is similar to a central heat pump, providing both heating and cooling from a single system. The difference is that ductless mini-splits feature wall-mounted indoor units, allowing them to deliver conditioned air to individual rooms with no ductwork required.

To learn more about heating, cooling, and ductless mini-splits, please call DNA HVAC at 706-289-0279.

Indoor Air Quality FAQs

How often should I replace my HVAC air filter?

Most filters should be replaced every one to three months, depending on usage, the type of filter you have, and your indoor air quality needs.

What are the best ways to improve indoor air quality?

In addition to adequate filtration, your other focuses should include ventilation, humidity control, and limiting indoor pollutants. For instance, always turn on the exhaust fan when showering or cooking, run a dehumidifier in the summer, and use low- or no-VOC paint and other products in your home.

How do UV germicidal lights work?

A specific range of UV light is effective at killing bacteria, viruses, and mold. By installing a germicidal lamp in your HVAC system, microorganisms are deactivated as the air circulates through the system for a cleaner home and healthier family.

Thermostats & Zoning FAQs

Can I really save with a programmable thermostat?

The key to energy savings is to program setback periods while you’re away or sleeping. Then, automatic recovery resumes a comfortable temperature before you return home or wake up. A setback of 10 degrees for at least eight hours a day can decrease your heating and cooling costs by up to 10%.

What is zoning?

Zoning utilizes multiple thermostats and dampers in the ductwork to independently control the temperature in different areas of your home. This makes every room more comfortable and increases the energy efficiency of your home.

Should I install a zoning system with programmable thermostats?

Multi-story homes stand to gain the most from a zoning system, especially if the house has large windows, recent additions, unused rooms, or a finished basement. Maximize the energy savings by installing a programmable thermostat in each zone.
