When your furnace or heat pump won’t keep up on a chilly coastal night, a few safe checks can save time, and sometimes fix the issue. Below are five quick steps Wilmington homeowners can try, plus the red-flag symptoms that mean it’s time to call a professional. If you need help now, our Heating Repair team services Wilmington, Carolina Beach, Kure Beach, Southport, and Bald Head Island.
Wilmington-area homes often rely on heat pumps, which can behave a little differently than a traditional furnace, especially during damp, chilly weather. If you’re not sure what system you have, no worries: these checks still apply.
5 safe homeowner checks
1) Thermostat & mode
Make sure your thermostat is set to Heat (not Cool) and the fan is on Auto, not On. Double-check your schedule—sometimes a programmed setback or Eco setting can make it feel like the system isn’t working when it’s just running less.
2) Filter
A dirty filter restricts airflow and can cause weak heat, uneven temps, or even icing (on heat pumps). If it looks dusty or gray, replace it. Most homes do best changing filters every 30–90 days depending on pets, allergies, and usage.
3) Power
Check the breaker for the air handler/furnace and (if you have a heat pump) the breaker for the outdoor unit. Also confirm the outdoor disconnect is on. If a breaker trips again after resetting once, stop there. Repeated trips can signal an electrical issue that needs a pro.
4) Vents/returns
Walk the house and make sure supply vents are open and not blocked by rugs, furniture, or curtains. Find your main return grille and clear it too—starving the system for airflow can make the heat feel weak and strain components.
5) Outdoor unit (heat pumps)
Clear leaves, pine straw, and windblown sand from around the outdoor unit and keep 18–24 inches of space for airflow. If you see light frost, that can be normal. But if it’s turning into thick ice or the unit is encased, it’s time to call for service.
When to call for heating repair service
If any of these are happening, skip troubleshooting and contact a technician:
- Breaker trips, burning/electrical smells, or loud metal-on-metal noises
- Solid ice on the outdoor unit after ~1 hour of run time, or constant defrosting
- The system runs non-stop with little/no heat, or rooms won’t warm up
- Repeated short cycles or error codes on the thermostat
These symptoms can point to control issues, failing motors, electrical faults, refrigerant problems, or airflow restrictions. The sooner you address them, the less likely you’ll face a bigger repair.

Common fixes our techs handle
When heating problems pop up, the cause is often a small component that’s worn out, dirty, or out of spec. Phillips Air Care technicians commonly repair or replace:
- Capacitors and contactors (common “no-start” culprits on heat pumps)
- Pressure/temperature sensors that trigger shutdowns or poor performance
- Inducer and blower motors that affect airflow and safe operation
- Flame sensors/ignition systems on gas furnaces (a frequent no-heat cause)
- Control boards and wiring issues behind cycling, error codes, and intermittent heat
- Airflow issues like dirty coils, blocked returns, duct problems, and clogged filters
We service all brands and back repairs with clear pricing and straightforward options—so you can choose the best path for your comfort and budget.
