Question 1

What should I check myself before calling for winter HVAC prep?

Accepted Answer

Swap the air filter if it has been in place for 60–90 days or more, remove leaves and debris from around your outdoor unit, and switch your thermostat to heat mode to confirm the system kicks on.

Question 2

Do you check for carbon monoxide risk during winter prep?

Accepted Answer

We do. Our technicians inspect the heat exchanger for cracks and test combustion safety on every gas furnace. We also strongly recommend installing working CO detectors near all sleeping areas.

Question 3

Is winter HVAC prep the same as a furnace tune-up?

Accepted Answer

It encompasses the full furnace or heat pump tune-up and adds winter-specific checks: emergency heat mode testing, outdoor unit winterization, thermostat cold-season programming, and a ductwork spot-check.

Question 4

Why does my furnace smell like something is burning?

Accepted Answer

A burning smell when you first turn on the furnace for the season is usually just dust burning off the heat exchanger and burners — it should go away within an hour. If the burning smell persists or appears mid-season, it could indicate an overheating motor, a wiring issue, or a foreign object in the ductwork. A persistent electrical burning smell always warrants a service call.

Question 5

When should I schedule fall furnace maintenance?

Accepted Answer

Schedule your fall furnace tune-up in September or early October, before the first cold snap hits Asheville. Waiting until November means you're competing with every homeowner whose furnace just failed on the first cold night. Early fall scheduling gives you priority, ensures any needed repairs are done before you actually need heat, and often comes with off-season pricing.

Question 6

How do I winterize my furnace?

Accepted Answer

Replace the air filter, clear any items stored within 3 feet of the furnace, check that all vents and returns throughout the house are open and unblocked, test the thermostat by setting it 5 degrees above room temperature and confirming the furnace starts and heats, and make sure your CO detectors have fresh batteries. Then schedule your professional tune-up — that covers the internal components you can't safely inspect yourself.

Question 7

Why does my furnace smell when I turn it on for the first time in fall?

Accepted Answer

That's dust that has settled on the heat exchanger and burners over the summer months burning off. It's normal and should dissipate within 30–60 minutes. If the smell is strong, open a few windows briefly. If it smells like burning plastic, rubber, or chemicals — or if the smell doesn't clear within a couple hours — shut the furnace off and call for service, as that could indicate a wiring issue or foreign object in the system.

Question 8

Should I run my furnace before winter to make sure it works?

Accepted Answer

Absolutely — test your furnace in early October before you actually need it. Set the thermostat to heat, raise it above room temperature, and confirm the furnace starts, the burners ignite, and warm air comes from the vents. This gives you time to schedule a repair or tune-up before the heating season rush. Discovering a dead furnace on the first 25-degree night in December is a miserable experience we help people avoid every year.

Question 9

How do I prepare my HVAC system for winter in Asheville?

Accepted Answer

Start with a professional furnace tune-up in September or October. Replace the air filter, test the thermostat, check CO detectors, clear debris from around outdoor equipment, and insulate exposed ductwork in crawlspaces and attics. Asheville's mountain climate can drop into the teens and single digits in January and February, so your heating system needs to be ready for sustained cold.
