Why are my upstairs bedrooms so much hotter?

Classic two-story problem: heat rises, attic ductwork leaks, and a single thermostat downstairs can't see the upstairs load. A pro can check duct balance, attic insulation, and whether zoning or a ductless unit makes sense.

Why is my heat pump blowing cold air in winter?

It may be in a defrost cycle (normal, brief), low on refrigerant, or running with a failed backup-heat element. If it blows cold for more than a few minutes, switch to emergency heat and have a pro diagnose it — running a struggling heat pump can spike your electric bill.

How often should I service my HVAC in Durham?

Twice a year is the norm here — a cooling tune-up in spring and a heating check in fall. Durham's long humid cooling season is brutal on AC components, and the winter freeze snaps expose any heating weakness, so skipping maintenance usually costs more than it saves.

Durham sits squarely in cooling country: summers are long, hot, and humid, and the air conditioner is the hardest-working appliance in most homes from late spring well into fall.

Spring severe weather adds its own risk: hail and high winds batter outdoor condensers, and a single storm can take an aging unit from limping to dead.

When heating or cooling trouble hits your Durham home — a furnace that won't fire on a freezing morning — AirFlow HVAC connects you with an independent local HVAC pro. Tell us what is happening and we will match you with a pro nearby, fast.

Homes here, and the HVAC problems they get

Local housing notes

Newer subdivisions with high-efficiency heat pumps — efficient, but only as reliable as their maintenance.
Historic-district homes with window units or mini-splits supplementing — or substituting for — central air.
Brick ranch homes on slabs or crawl spaces, many with original duct systems leaking into unconditioned space.

Common local HVAC issues

Frozen evaporator coils: restricted airflow plus long runtimes freeze coils solid, and the system blows warm until it thaws.
Uneven cooling: single systems serving two stories leave upstairs bedrooms hot while the main floor stays fine.
Freeze-snap furnace failures: ignitors, flame sensors, and cracked heat exchangers reveal themselves on the coldest nights.
Algae-clogged condensate drains: humid-season slime blocks drain lines, and overflow damages ceilings under attic air handlers.
Tobacco-mill lofts: converted warehouses with tall ceilings and single-pane steel windows — ductless zones and destratification fans beat one giant system.
Duke off-campus housing: rentals near campus cycle tenants every August — pre-lease HVAC checkups catch dead capacitors before the first heat wave.
Research-park dust: spring pine pollen plus construction dust double-team outdoor coils — a mid-spring rinse keeps efficiency up.

Durham FAQs

Almost always restricted airflow — a clogged filter, dirty coil, or blocked return — or low refrigerant. Turn the system off and let the ice melt completely, then have a pro find the underlying cause; running it frozen can damage the compressor.
