Most Triangle heating systems fail on the first genuinely cold night of the year, and almost none of them fail without warning. Boer Brothers Heating & Cooling has serviced heating systems across Chapel Hill, Durham, Cary, Carrboro, and Apex since 2007, and the pattern barely changes. Here’s when to schedule, what a real inspection covers, and which parts of it matter most for the equipment most Triangle homes actually run.
When should you schedule heating maintenance in the Triangle?
Schedule it in September or early October, before the first cold snap and before you’ve run the heat. The reason is specific to our climate: Triangle fall weather swings between 70s in the afternoon and 40s overnight, so systems here start cycling weeks before anyone consciously turns the heat on. By the time you notice the heat is running, it has already been working for a month.
The second reason is availability. The week the temperature first drops below freezing is the week every HVAC company in the Triangle takes emergency calls, and a tune-up competes with people who have no heat at all. Booking in the shoulder season also means we find a failing igniter or a weak capacitor while it’s a scheduled repair instead of an after-hours one. If your heat has already stopped, start with what to check when your heat stops working.
Does a heat pump need more maintenance than a furnace?
Yes. A heat pump accumulates roughly twice the annual runtime of a furnace, because the same equipment cools your house all summer. A gas furnace sits idle from April to October; a heat pump gets no off-season. That single difference drives most of what we find on fall inspections here.
Not sure which one you have? Look at the outdoor unit. If it runs in both summer and winter, it’s a heat pump.
Three consequences of that runtime:
- Dirt carries over. The coil that struggled through August humidity is the same coil that has to pull heat out of cold air in January, and nobody cleans it between seasons.
- Refrigerant charge shows up differently. A slightly low charge is easy to miss in cooling season and obvious in heating season, usually as auxiliary heat running when it shouldn’t. That’s the most expensive symptom we see on a Triangle power bill.
- Defrost controls only get tested in winter. The defrost cycle sits unused for six months. When it fails, the outdoor unit ices over and the system falls back to electric resistance heat, which costs several times more to run.
If your bill jumps in December and the house still feels cold, the problem usually isn’t the thermostat. It’s one of these three, and all three are cheaper to find in October.
What does a heating tune-up actually include?
Boer Brothers runs a 40+ point inspection built to each manufacturer’s specifications, not a generic checklist. The visit covers the mechanical, electrical, and airflow sides of the system rather than just swapping a filter.
| Area | What we check | What it prevents |
|---|---|---|
| Electrical | Connections tightened, capacitors and contactors tested, amp draw measured | The most common no-start call in January |
| Heating operation | Ignition sequence, temperature rise, refrigerant charge, auxiliary heat staging | High bills and a system that runs constantly without warming the house |
| Heat pump specific | Defrost cycle, reversing valve operation, outdoor coil condition | An iced outdoor unit and a winter of backup electric heat |
| Airflow | Filter, blower wheel, ductwork inspection, static pressure | Cold rooms, short cycling, premature blower failure |
| Safety (gas equipment) | Heat exchanger, venting, flame sensor, gas pressure | Carbon monoxide exposure and combustion problems |
| Drainage | Condensate pump treatment, drains cleared | Water damage and shutdowns on a heat pump running in cooling mode |
One row is worth pointing at. Ductwork inspection catches the problem homeowners most often blame on the equipment: if one bedroom is always cold, the system is usually fine and the duct serving that room is not.
What safety checks matter if you heat with gas?
Combustion equipment gets checks a heat pump doesn’t need, which is why we don’t recommend skipping a professional visit on gas or oil. We inspect the heat exchanger, the venting, and the ignition system on every gas furnace we service. A cracked heat exchanger can let combustion gases into the air your family breathes, and it isn’t something you can see or smell from the hallway.
The CDC is direct about this: have your heating system, water heater, and any other fuel-burning appliance serviced by a qualified technician every year. More than 400 Americans die each year from unintentional carbon monoxide poisoning unrelated to fires, and more than 100,000 end up in an emergency department.
Two points from the CDC’s detector guidance go further than the advice most people have heard. Install CO alarms near every sleeping area, not simply one per floor. And replace the alarm itself every five years, or per the manufacturer’s instructions, because a detector with a working battery isn’t necessarily a working detector.
The CDC also notes that CO symptoms are often described as flu-like, which is why it gets missed in the season when everyone has a cold. If your family feels better after leaving the house and worse after coming home, get out and call. Don’t wait for the tune-up.
What you can do yourself this fall
None of this replaces the safety and refrigerant work above, but it reduces how hard the system has to run, and it costs nothing.
- Clear leaves and yard debris from around the outdoor unit. Heat pumps need airflow across that coil all winter, and fall is when it gets buried.
- Seal gaps around doors and windows and replace worn weather stripping. Highest-return hour you can spend on a Triangle home in October.
- Replace the filter, then check it monthly once the heat is running rather than on a set schedule.
- Test your CO and smoke detectors when the clocks change, and check the manufacture date on the CO units while you’re there.
- Keep supply vents and the indoor unit clear. Furniture over a return is a surprisingly common cause of “the system is too small.” While you’re there, standing water or torn duct insulation is worth a call.
What does Boer’s Maintenance Club include?
Boer Brothers runs a Maintenance Club for homeowners who’d rather not track any of this, starting as low as $16.50 per month with a yearly agreement. It covers the full inspection above on a schedule, plus the benefits that matter when something does go wrong.
- 40+ inspection points per manufacturer specifications
- 10% discount on part repairs and system enhancements
- 30-day Boer Brothers Guarantee, which covers return trip and diagnostic fees
- Preseason scheduling, so you get the appointment before the rush
- Condensate pump treatment, drains cleared, and ductwork inspection included
Preseason scheduling is the benefit members actually use. It’s the difference between picking your appointment in September and taking what’s left in January.
“Boer Brothers does an excellent job! I have a maintenance program with them and it works out very well and very inexpensive. The guys that come out are trained and very professional. I highly recommend.”

Frequently Asked Questions
How often does a heat pump need maintenance in the Triangle?
Twice a year, once before cooling season and once before heating season. Boer Brothers recommends this for heat pumps specifically because the same equipment runs in both seasons, roughly doubling annual runtime compared to a furnace and air conditioner pair. A gas furnace paired with a separate air conditioner can usually run on one annual visit per system.
Do I need my heating serviced before winter?
Yes, and the reason depends on what you have. On gas or oil, it’s a safety question, which is why the CDC puts annual professional service on its carbon monoxide prevention list. On a heat pump it’s a cost question: a failing defrost board or a low refrigerant charge shows up on the power bill every month of the winter.
Is a heating tune-up the same as a maintenance plan?
No. A tune-up is a single visit. Boer Brothers’ Maintenance Club is an ongoing agreement that includes the scheduled visits plus repair discounts, preseason scheduling, and coverage of return trip and diagnostic fees. If you only ever plan to have the system looked at once, a tune-up is the right purchase.
My heat is blowing cool air. Is that a problem?
Not necessarily, if you have a heat pump. Carrier puts normal heat pump supply air at 90 to 100 degrees, cooler than furnace air, so it can feel cool against your skin while still heating the house correctly. It’s a problem if the house isn’t reaching the set temperature, if auxiliary heat runs constantly, or if the outdoor unit is covered in ice.
Do I still need maintenance on a new system?
Yes, and most manufacturers require documented annual maintenance to keep the equipment warranty valid. Skipping it on a system under warranty is the one case where maintenance can cost you more than it saves. We provide the documentation on every visit.
What happens if I skip a season?
Usually nothing visible, which is why people skip a second one. The cost shows up as reduced efficiency on the monthly bill and as shorter equipment life, and eventually as a failure on the coldest night of the year, when emergency rates apply and parts availability is at its worst.
