Professional Heating Tune-up in Morrisville, NC

Schedule your heating tune-up in September or October. That's the window. Early enough that HVAC companies aren't slammed with emergency calls yet, late enough that your system hasn't been sitting idle long enough to develop problems you won't know about until the first cold night.

In the Triangle, heating season runs roughly November through March. By mid-November, most HVAC companies — including ours — are booking out a week or more. If your system fails its first real test of the season, you're competing with every other homeowner whose furnace picked the same night to quit.

A tune-up in early fall is the opposite of that scenario. It's calm, scheduled, and thorough.

What Happens During a Heating Tune-Up

A heating tune-up isn't a quick once-over. Our techs spend 45-60 minutes going through your system component by component. The checklist differs depending on whether you have a heat pump or a gas furnace, because the two systems have very different failure points.

For Gas Furnaces (Natural Gas or Propane):

- Combustion analysis — we measure CO levels in the flue to confirm the burners are firing cleanly
- Heat exchanger inspection — cracks here are a carbon monoxide risk and the most serious thing we check for
- Igniter condition — we visually inspect for hairline cracks that predict failure
- Flame sensor cleaning — a dirty flame sensor causes the most common furnace nuisance shutdowns
- Gas pressure verification — too high wastes gas, too low causes incomplete combustion
- Blower motor amp draw — elevated amps mean the motor is working harder than it should
- Air filter replacement
- Thermostat calibration check
- Safety control testing — limit switches, pressure switches, rollout switches

For Heat Pumps:

- Refrigerant pressure check — low charge means your heat pump can't extract enough heat from outdoor air
- Reversing valve operation — confirms the system properly switches between heating and cooling
- Defrost cycle test — heat pumps need to defrost the outdoor coil in winter; a failed defrost board means ice buildup and no heat
- Auxiliary heat strip check — confirms backup electric heat is functional
- Outdoor coil cleaning — debris blocks airflow and reduces efficiency
- Indoor coil inspection
- Blower motor and capacitor test
- Thermostat calibration

Most Triangle homes built after 2000 use heat pumps as their primary heating system. Homes with gas furnaces are common too, especially in older Cary and Raleigh neighborhoods connected to Dominion Energy natural gas lines. If you're not sure what you have, look at your outdoor unit. If it runs in both summer and winter, it's a heat pump.

What a Tune-Up Catches Before It Becomes a Breakdown

Here are real examples from tune-ups our techs performed last fall in Apex and Cary:

A cracked hot surface igniter that hadn't fully broken yet. The homeowner's furnace was starting fine, but the crack meant it could fail any time. Replacement during the tune-up: about $150. Emergency replacement on a Saturday night in December: $300+ with the after-hours fee.

A heat pump with refrigerant charge 15% below spec. The system was heating, but it was running longer cycles and using more auxiliary heat than necessary. The homeowner's Duke Energy bill was running $30-40 higher per month without them knowing why.

A gas furnace with early signs of heat exchanger corrosion. Not cracked yet, not leaking CO yet, but trending in that direction. The homeowner was able to plan and budget for a furnace replacement in the spring instead of facing an emergency decision in February.

A blower motor drawing 2 amps above its rated capacity. Still running, but overheating on longer cycles. The capacitor was weak. A $15 capacitor swap during the tune-up prevented a $400-600 blower motor replacement later.

Why Fall Specifically

People ask why not just get the tune-up whenever, maybe in December after Thanksgiving. The reason is timing and access. In September and October, we can schedule same-day or next-day in most cases. Our techs aren't rushing between emergency calls, so your tune-up gets full attention. And if we do find something that needs repair, parts are readily available and there's no urgency premium.

By December, parts suppliers are running low on common items like igniters and control boards. Our schedule is packed with no-heat emergencies. A tune-up that turns into a repair can mean a longer wait for parts and a longer wait for the return visit.

Cost and Scheduling

Our heating tune-up is $49. That covers the full inspection for either system type. If we find a repair need, we'll quote it separately — you're never obligated to proceed. Same-day scheduling is available most days during September and October, with morning and afternoon windows.

We service Apex, Cary, Raleigh, Durham, Holly Springs, and Fuquay-Varina. As a veteran-owned company with 700+ five-star reviews, we've built our reputation on honest assessments. If your system is in good shape, we'll tell you exactly that. No invented problems, no scare tactics. Just a clean bill of health and peace of mind heading into winter.
