There is a simple way to decide whether a fall tune-up saves money, and it’s simple as doing the math. Put two columns on a page. In the first, write what an October visit costs and what it includes. In the second, write what a Triangle winter tends to cost a heating system that skipped it. This post fills in both columns, item by item, so the comparison is yours to make. For the safety and readiness side of the fall visit, our post on getting your furnace ready for fall covers it.
What goes into October
An October maintenance visit is one appointment on a mild day, and it includes cleaning the indoor and outdoor coils, measuring the refrigerant charge with gauges, testing the auxiliary heat strips and the defrost control on a heat pump, cleaning the burners and inspecting the heat exchanger on a gas or oil furnace, testing the capacitor and motors under load, tightening the electrical connections, clearing the condensate drain, measuring airflow, and calibrating the thermostat. The readings are recorded and reviewed with you. That is the whole column, and for members of the VIP Club the visit is part of the plan rather than a separate charge.
Understanding the costs once January arrives
Most Durham homes heat with a heat pump, and a heat pump’s winter cost has two parts. On the mild days that make up most of a Triangle winter, it moves heat from the outdoor air at modest cost. On the nights that drop into the 20s, which come from November into March here, it switches on electric auxiliary heat strips that draw several times the power, and those nights account for a large part of the season’s cost. A system with a dirty outdoor coil pulls heat from the air poorly and leans on the strips sooner. A system low on refrigerant leans on them more. A dirty filter restricts airflow so the house takes longer to reach the set point. Each of those adds hours at strip rates, and the October visit removes all three. The test is January’s bill against last year’s for similar weather, and homeowners who have a neglected system tuned for the first time often see the difference on the first full month.
Counting the strips that failed last year
The auxiliary heat strips are the part of a heat pump that runs least and fails most quietly. A strip that burned out last February has sat unnoticed through spring, summer, and fall, and it announces itself on the first night in the 20s, when the house will not get above 60. That is a repair call on a cold night, often at after-hours rates, for a part that would have shown up on a technician’s meter in October as a simple test. The defrost control behaves the same way, and when it fails, lets the outdoor coil ice over and strains the compressor every cold morning.
Recognizing the repairs that turned expensive
A tired capacitor in October is an inexpensive part. Left alone, it starts the motors harder every cycle, and by February it has taken the blower motor or the compressor with it. A loose connection in October is a tightening. Left alone, it heats, corrodes, and burns a terminal. A cracked heat exchanger on a gas or oil furnace, which the October inspection is designed to find, is a safety matter first and a furnace replacement second, and it is far better found in October than discovered by a carbon monoxide detector in January. Every one of these is a line in the second column that the first column erases.
The warranty that was not honored
Most equipment manufacturers require documented professional maintenance to honor a parts warranty, and the compressor warranty in particular. A compressor that fails in year six of a ten-year warranty is a covered repair with a folder of tune-up receipts and a denied claim without one. That single line can be larger than every other line in the second column combined.
The replacement that came early
The largest line is the one no bill shows. A heat pump in the Triangle that receives its spring and fall visits tends to reach 12 to 15 years; a neglected one often gives out between 9 and 11. The difference is several years of the most expensive purchase a homeowner makes for the house, deferred, and the mechanism is plain: a compressor that runs at its design temperature on clean coils, starts on a healthy capacitor, and draws through tight connections wears more slowly than one that does not.
Reading the two columns
The first column is one visit. The second is a higher bill every month of the heating season, a cold-night repair call, a repair that grew, a warranty that may not apply, and a replacement years early. Not every line in the second column happens every winter, and that is the point: any one of them costs more than the first column, and a heating system that skips the fall visit year after year eventually collects several. The habits that keep the first column working through the season are ordinary: a filter every one to three months, a thermostat set and left rather than moved, and vents kept open.
