If you have owned your home for a long time, its systems have aged alongside you, and the arithmetic sneaks up. The heat pump that was new when the kids were in middle school is fifteen. The water heater you replaced after the 2014 ice storm is past ten. The generator that got you through Helene has run more hours than you realize. None has failed, which is why nobody has looked closely. This post covers the inspections that tell you where each major system stands, what each one finds, and how to use the results to plan repairs and replacements on your schedule rather than the equipment’s.
Start by finding the ages
Before scheduling anything, read the labels! The outdoor heating and cooling unit has a nameplate with a manufacture date or a serial number that encodes one. The water heater’s label does the same. A standby generator’s controller shows its total run hours and often its install date. Note each next to its typical lifespan: 12 to 15 years for a heat pump or air conditioner in Columbia’s long cooling season, 15 to 20 for a gas furnace, 8 to 12 for a tank water heater, about 20 for a tankless unit, and 20 to 30 for a standby generator with regular service. Anything near the top of its range belongs on the list below.
The heating and cooling evaluation
A full evaluation of an older system goes beyond a tune-up. The technician measures refrigerant pressures and temperatures to confirm the charge and the compressor’s condition, tests the capacitor and motors under load, measures airflow and static pressure to judge the ductwork, and on gas equipment inspects the heat exchanger for the cracks that come with age and can leak carbon monoxide. The result is how much life the system has left and what keeping it running costs versus replacing it. In a home that has kept up with maintenance, that picture usually shows a system aging well. In one that has not, the replacement decision is often closer than assumed, and October is a far better month to learn that than July.
The plumbing assessment
Plumbing ages quietly, and a home lived in for decades has supply lines, valves, and drains that were installed once and not looked at since. A plumbing assessment measures water pressure at the main and the fixtures, identifies the pipe material and its condition where it is visible, tests every shutoff valve, checks each drain’s flow, and inspects the crawl space for moisture and uninsulated pipe. For homes built between the late 1970s and mid 1990s, the assessment specifically looks for polybutylene supply pipe, a gray plastic that fails with age and that many insurers will not cover. Where the drains have a history of clogs, a camera inspection of the sewer line shows root intrusion, cracks, and separated joints before the line fails.
The water heater check
The water heater fails without warning and does the most damage when it does, especially in the many Columbia homes where it sits above finished space. An inspection checks the age, flushes sediment, tests the temperature and pressure relief valve, checks the anode rod that protects the tank from corrosion, and looks for the moisture at the base that means the tank has begun to fail. For a heater past ten years, the useful outcome is a plain answer on whether to replace it now or within a year or two, and a comparison of a new tank against a tankless water heater for a household whose hot water needs have changed.
The generator checkup
A standby generator a decade or more old has a battery on its third or fourth replacement, a transfer switch with thousands of operations behind it, and an engine that has run through several long outages. A generator checkup reads the fault history, tests the battery under load, checks fuel pressure, changes the oil and filters, inspects the enclosure for corrosion and pests, and runs the unit under a full load during generator service, which is the only way to know it will carry the house. For an aging generator, the technician can also tell you whether the unit is still sized for the home, since a heat pump replaced along the way may draw more than the generator was installed to handle.
The ductwork and air quality review
Ductwork ages too, and in Columbia most of it runs through attics that reach 130 degrees in summer and crawl spaces that stay damp. Over decades, joints separate, insulation slides off, and the ducts accumulate dust and, where moisture reaches them, growth. A duct review measures how much conditioned air is being lost, inspects the runs by camera, and tells you whether cleaning, sealing, or air duct replacement makes sense. It also looks at the crawl space, since a damp crawl space is behind most indoor air problems in a Midlands home, and a dehumidifier or sump pump at the source does more than any filter upstairs.
Turning the results into a plan
The point of inspecting everything at once is the plan. With each system’s age and condition written down, you can see which replacement comes first, which repairs buy meaningful time, and how much to set aside each year. Some homeowners use the results to schedule a replacement for a mild month when prices can be compared. Others learn that a system they worried about has years left. Either way, the decisions get made with numbers rather than in an emergency, which for a home you intend to stay in is worth a few appointments.
Schedule the inspections
2nd Wind Heating & Air Conditioning has served greater Columbia since 1985. If your systems are approaching the ages above, schedule an inspection online or through the 24/7 chat on our website. The technician will document each system on video, give you a written summary of its condition and remaining life, and lay out the options with prices.
