Your Heating & Cooling Questions Answered by Outer Banks HVAC Experts:
What does HVAC stand for?
HVAC stands for Heating, Ventilation, and Air Conditioning. It refers to the systems used to regulate indoor temperature, humidity, and air quality in homes and businesses.
How often should I service my HVAC system?
We recommend servicing your HVAC system twice a year—once in the spring for cooling and once in the fall for heating. Regular maintenance extends system life, improves efficiency, and helps prevent costly breakdowns.

Air Conditioning FAQs
Why is my air conditioner running but not cooling my home?
This could be due to several issues including low refrigerant, dirty coils, clogged air filters, or a faulty thermostat. Our technicians can diagnose and repair AC issues quickly to restore your comfort.
When should I replace my air conditioner?
Most AC units last 10–15 years. If your system is aging, requires frequent repairs, or your energy bills are rising, it may be time to consider a high-efficiency replacement.

Heating FAQs
What type of heating system is best for the Outer Banks?
Heat pumps are ideal for the Outer Banks climate. They offer energy-efficient heating in the winter and cooling in the summer. For colder inland areas or larger homes, a dual-fuel system may be more effective.
Why is my furnace making a strange noise?
Unusual sounds like banging, screeching, or rattling can indicate mechanical problems, worn parts, or airflow issues. It’s best to have a professional inspect the system before it worsens.
HVAC System Care & Performance
How can I improve my indoor air quality?
Air quality can be improved with clean air filters, routine HVAC maintenance, and upgrades such as UV air purifiers or whole-home dehumidifiers—especially helpful in coastal areas like the OBX.

More HVAC Questions
How do I know if my HVAC system is still under warranty?
Check the label on the outside of your indoor or outdoor unit for the model number, serial number, and manufacture date. Most major brands let you look up warranty status online with the serial number, and many require the system to be registered within a set time after installation to get full parts coverage. If you’re not sure, AirHandlers OBX can help you check your coverage before any repair work begins.
Does it matter how loud my heating and cooling system is?
Yes. Outdoor units sit close to decks, bedrooms, and neighbors, which matters a lot on the Outer Banks where homes are close together and guests spend time outside. Look for the decibel (dB) rating when comparing systems: variable-speed heat pumps and ductless mini-splits are usually much quieter than older single-stage units. A noise that gets louder over time can also be an early sign that something needs service.
What temperature should I set my thermostat to?
For a good balance of comfort and energy savings, the U.S. Department of Energy suggests about 78°F in summer and 68°F in winter while you’re home, and adjusting a few degrees when you’re away or asleep. For vacation homes that sit empty, don’t shut the system off: keeping it running (and controlling humidity) helps prevent mold, musty odors, and moisture damage in our coastal climate.
How do I know if my A/C unit is the right size?
Bigger isn’t always better. An oversized unit cycles on and off too quickly and doesn’t remove enough humidity, which leaves the home feeling clammy. An undersized unit runs constantly and struggles on the hottest days. The right size depends on square footage, insulation, windows, sun exposure, and ductwork. We do a proper load calculation before recommending a replacement system.
How can I make my heating and cooling system last longer and run more efficiently?
- Schedule professional tune-ups twice a year (spring for cooling, fall for heating).
- Replace or clean air filters on schedule.
- Keep the outdoor unit clear of sand, plants, and debris, and rinse salt buildup off the coils.
- Seal and insulate leaky ductwork.
- Use a programmable or smart thermostat.
How can I get rid of odors in my home?
Lingering odors often come from high humidity, dirty coils or drain pans, or contaminated ductwork. Fixing the source comes first. After that, a whole-home dehumidifier, air purification system, or UV light can keep the air fresh, which is especially helpful for rental properties between guests.
